    Plasma-treated water (PTW), i.e. distilled water (DW) exposed to low-temperature atmospheric pressure helium plasma, exhibited strong bactericidal activity against Escherichia coli in suspension even within a few minutes of preparation. This effect was enhanced under acidic conditions. The bactericidal activity of PTW was attenuated according to first-order kinetics and the half-life was highly temperature dependent. The electron spin resonance (ESR) signal of an adduct of the superoxide anion radical (O-2(-center dot)) was detected in an aqueous solution using a spin-trapping reagent mixed with PTW, and adding superoxide dismutase to the PTW resulted in a loss of the bactericidal activity and weakening of the ESR adduct signal of O-2(-center dot) in the spin-trapping. These results suggest that O-2(-center dot) plays an important role in imparting bactericidal activity to PTW. Moreover, molecular nitrogen was required both in the ambient gas and in the DW used to prepare the PTW. We, therefore, suggest that the reactive molecule in PTW with bactericidal effects is not a free reactive oxygen species but nitrogen atom(s)containing molecules that release O-2(-center dot), such as peroxynitrous acid (ONOOH) or peroxynitric acid (O2NOOH). Considering the activation energy for degradation of these species, we conclude that peroxynitric acid stored in PTW induces the bactericidal effect.

    The biological flux and lifetime of methanol in anoxic marine sediments are largely unknown. We herein reported, for the first time, quantitative methanol removal rates in subsurface sediments. Anaerobic incubation experiments with radiotracers showed high rates of microbial methanol consumption. Notably, methanol oxidation to CO2 surpassed methanol assimilation and methanogenesis from CO2/H-2 and methanol. Nevertheless, a significant decrease in methanol was not observed after the incubation, and this was attributed to the microbial production of methanol in parallel with its consumption. These results suggest that microbial reactions play an important role in the sources and sinks of methanol in subseafloor sediments.

    Ion-exchange chromatographic analysis of peroxynitric acid (O2NOOH) was performed by combining an acidic eluate with an UV-vis detector and immersing the separation column in an ice-water bath. The decomposition behavior of peroxynitric acid in the solution was also studied using this system. The fraction for the peroxynitric acid peak was collected. Ion-exchange chromatographic analysis of this fraction, after standing at room temperature for 24h, showed that the decomposition products were mainly nitrate ions with a very small amount of nitrous acid. The peroxynitric acid peak area correlated perfectly with the total amount of decomposition products. The ion-exchange chromatographic isolation allowed us to evaluate the molar extinction coefficient of peroxynitric acid precisely in a wider wavelength range than previous reports. The value decreases monotonically from 1729 +/- 26 M-1 cm(-1) at 200 nm to 12.0 +/- 0.5 M-1 cm(-1) at 290 nm. (C) 2015 Elsevier B.V. All rights reserved.

    The formation mechanisms of gamma-ray-induced carboxyl (HOCO) and methyl radicals in CO2 + methane mixed gas hydrates, which are inclusion compounds of H2O, CO2, and methane, were investigated. The HOCO and methyl radicals were observed in CO2 + methane mixed gas hydrates by electron spin resonance (ESR) at 120 K after irradiation at 77 K. The amounts of the HOCO and methyl radicals induced in the mixed hydrates are much higher than those in pure CO2 and methane hydrates. Both radicals are synergistically formed in the mixed hydrates by efficient reactions between the guest molecules (CO2 and methane) and the active species (electron, proton, and hydroxyl radical) induced from H2O.

    Clathrate hydrates preserve active species more stably than the other icy materials and investigation of the behavior of the active species elucidates the physicochemical properties of clathrate hydrates like guestguest interaction. Color of the tert-butylamine clathrate hydrate changes to blue after gamma irradiation and is bleachable with visible light. The electron spin resonance (ESR) spectrum at 120 K mainly consists of a triplet signal of the C-centered radical NH2C(CH3)(2)CH2 center dot together with a single signal at g = 2.0008. The latter signal disappears after light exposure. These results indicate that both the blue color and the single ESR signal are derived from trapped electrons in the hydrate. They thermally decay around 140160 K by the first-order reaction, and the activation energy is 27 kJ/mol. Since tert-butylamine molecules can capture protons due to the high proton affinity, electrons may remain in the hydrate without reacting with protons, making the hydrate blue after gamma irradiation. The long-lived trapped electrons in the tert-butylamine hydrate have an advantage to investigate those in icy materials because tert-butylamine hydrate is nonionic and has a tetra-coordinated host water network like crystalline ice without any substitution for water molecules.

    The carboxyl (HOCO) radical, which is an important species in atmospheric chemistry and combustion, is an intermediate in the reaction: CO + OH -> CO2 + H and serves as a hydrogen donor to the reaction partners. The cis-HOCO radical, one of the ground-state HOCO radicals, is supposed to be decomposed into CO2 and the hydrogen atom by a tunneling effect. In order to prove the hypothesis, we performed electron spin resonance (ESR) measurements to investigate the decay mechanisms of the ground-state HOCO and DOCO radicals in gamma-ray-irradiated CO2 hydrates, which may hold the radicals stably. The ground-state HOCO and DOCO radicals decayed according to a second-order decay model and transformed into formic acid and CO2. The ratio of the decay rate constants of HOCO and DOCO radicals shows a good agreement with that in the kinetic isotope effect for the hydrogen and deuterium abstraction reactions. These results indicate that they react with another HOCO radical in the adjacent hydrate cage without the tunneling effect. This implies that the ground-state HOCO radicals are not decomposed by the tunneling effect but are decayed through reactions with some atoms, molecules, and/or radicals even in the gas phase. In addition, the hydrogen-atom hopping through the temporary hydrogen bonds between the HOCO radical and CO2 results in a seeming diffusion of the HOCO radicals in the CO2 hydrate; this would be an important concept for the studies of the radical diffusions and the supply of hydrogen atoms in gas, liquid, and solid phases.

    Radiation-induced free radicals in hydrated magnesium sulfate, which are thought to be present on the surface of Europa, one of the Jovian moons, have been studied by electron spin resonance (ESR). ESR signals of both atomic hydrogen (H center dot) at g = 2.0023 and sulfite radical (SO3-center dot) at g = 2.0029 are observed in epsomite (MgSO4 center dot 7H(2)O) and in quenched samples of magnesium sulfate solutions, after gamma-ray irradiation at 77 K. Atomic hydrogen disappears at temperatures above 90 K. The sulfite radical starts to decay above 190 K in the quenched sample of 10% magnesium sulfate solution, whereas in epsomite, it is stable even at 260 K. The sulfite radical accumulates at low ambient temperatures, and is a promising candidate for estimating the age of hydrated magnesium sulfate, especially in extraterrestrial environments.

    Electron spin resonance (ESR) spectra of butyl radicals induced with gamma-ray irradiation in the simple isobutane (2-methylpropane) hydrate (prepared with deuterated water) were investigated. Isothermal annealing results of the gamma-ray-irradiated isobutane hydrate reveal that the isobutyl radical in a large cage withdraws a hydrogen atom from the isobutane molecule through shared hexagonal-faces of adjacent large cages. During this "hydrogen picking" process, the isobutyl radical is apparently transformed into a tert-butyl radical, while the sum of isobutyl and tert-butyl radicals remains constant. The apparent transformation from isobutyl to tert-butyl radicals is an irreversible first-order reaction and the activation energy was estimated to be 35 +/- 3 kJ/mol, which was in agreement with the activation energy (39 +/- 5 kJ/mol) of hydrogen picking in the gamma-ray-irradiated propane hydrate with deuterated water.

    To understand plasma-induced chemical processing in liquids, we investigated the formation of free radicals in aqueous solution exposed to different types of non-contact atmospheric-pressure helium plasma using the spin-trapping technique. Both hydroxyl radical (OH center dot) and superoxide anion radical (O-2(-)center dot) adducts were observed when neutral oxygen gas was additionally supplied to the plasma. In particular, O-2(-)center dot can be dominantly induced in the solution via oxygen flow into the afterglow gas of helium plasma. This type of plasma treatment can potentially be used in medical applications to control infectious diseases, because the O-2(-)center dot is crucial for sterilization of liquids via atmospheric-pressure plasma.

    To investigate the molecular interaction between guest species inside of the small and large cages of methane + propane mixed gas hydrates, thermal stabilities of the methyl radical (possibly induced in small cages) and the normal propyl and isopropyl radicals (induced in large cages) were investigated by means of electron spin resonance measurements. The increase of the total amount of the normal propyl and isopropyl radicals reveals that the methyl radical in the small cage withdraws one hydrogen atom from the propane molecule enclathrated in the adjacent large cage of the structure-H hydrate. A guest species in a hydrate cage has the ability to interact closely with the other one in the adjacent cages. The clathrate hydrate may be utilized as a possible nanoscale reaction field.

    The molecular orientation and dynamics of the organic stable radicals such as 2,2,6,6-tetramethyl-1-piperidinyl-1-oxyl (TEMPO) or 4-hydroxy-TEMPO (TEMPOL) included in the one-dimensional (1-D) organic nanochannels of 2,4,6-tris-4-(chlorophenoxy)-1,3,5-triazine (CLPOT) were investigated by examining the inclusion compounds (ICs) diluted by the co-inclusion of non-radicals using ESR spectroscopy. Spectral simulation showed that the axial rotation of TEMPO or TEMPOL molecules is excited in the nanochannels with activation energies of 8 and 7?kJ?mol-1, respectively. The rotation axis was estimated to be tilted towards the principal x direction in the axis system of the g-tensor of the respective radicals. This is quite different from that for similar ICs in the nanochannels of tris(o-phenylenedioxy)cyclotriphosphazene (TPP), in which the radicals are axially rotating around the principal axis y of the g-tensor. The difference is attributed to the larger nanospace of the CLPOT nanochannels. Copyright (C) 2012 John Wiley & Sons, Ltd.

A frequency doubled Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser (532 nm) is used as the lidar light source, and the Raman signals at similar to 1273 and similar to 1380 cm(-1) from CO2 dissolved in water were detected. In lidar application, CO2 dissolved in water was identified in glass bottles 20 m away by using the CO2 Raman band at similar to 1380 cm(-1). (C) 2011 The Japan Society of Applied Physics

  • In-situ Raman Observation on Aqueous Solution around Tetra-n-Butyl Ammonium Bromide Semi-Clathrate Hydrate

    To confirm the hydrate-like structures in tetra-n-butyl ammonium bromide (hereafter, TBAB) aqueous solution with tetragonal TBAB hydrates, the TBAB hydrate crystal and its stoichiometric aqueous solution at equilibrium state and during dissociation process have been investigated by means of in-situ Raman micro-spectroscopic observation. At equilibrium state and during dissociation process, the conformations of TBAB changed drastically around the surface between hydrate and aqueous phase, and the hydrate-like conformations did not appear in aqueous phase near the crystal. On the other hand, a broad signal in aqueous phase gradually changed during hydrate dissociation and then it converged after about 45 minutes. This implies the existence of residual that exhibits relatively slow structural relaxation in aqueous phase.

  • In-situ ESR Observation of Free Radicals in Gas Hydrates under High Pressure

    Methyl radical in gamma-irradiated methane hydrate with heavy water (D2O) has been investigated by electron spin resonance (ESR) using the sample tube designed for in-situ high-pressure measurements. Methyl radical, hydrogen atom, and deuterium atom were observed at 77 K. Hydroxyl radical (OH) was not detected and it is concordant with the previous results on gamma-irradiated methane hydrate with H2O. Although small signals of both hydrogen and deuterium atoms were found at 120 K, only methyl radicals remained at 210 K. The decay of the methyl radical was relatively slow under the pressurization with methane. The decay mechanism of the methyl radical partially depends on thermodynamic stability of methane hydrate.

    It has been established that East Asian summer monsoon intensity varies with Dansgaard-Oeschger cycles, suggesting a connection between the climates of East Asia and the North Atlantic on a millennial timescale. However, the dynamics of such a connection are still unsolved. Here we demonstrate that temporal changes in the provenance of aeolian dust in Japan Sea sediments, which we interpret to reflect changes in the westerly jet path over East Asia, exhibit variations in harmony with Dansgaard-Oeschger cycles. The dominance of dust with a Mongolian Gobi provenance during stadials suggests a westerly jet axis located to the south of the Himalaya-Tibetan Plateau throughout most of the year, whereas the co-dominance of dust from both the Taklimakan Desert and the Mongolian Gobi during interstadials suggests that the westerly jet axis jumped to the north of the Tibetan Plateau at latest in summer. As the shift of the westerly jet axis to the north of the Tibetan Plateau is closely related to the onset of the East Asian summer monsoon, changes of the westerly jet path apparently critically affect the teleconnection between the climates of Asia and North Atlantic on a millennial timescale.

    Electron spin resonance (ESR) study on gamma-irradiated synthetic ethylene hydrate was performed to investigate induced radicals and their thermal stability. ESR spectra of induced 3-butenyl radical (center dot CH2C2H3=CH2, g = 2.0039 +/- 0.0005, A(alpha) =2.2 +/- 0.1 mT and A(beta) =3.0 0.1 mT) and induced ethyl radical (center dot C2H5, g = 2.0044 +/- 0.0005, A(alpha) = 2.2 +/- 0.1 mT and A(beta) = 2.7 0.1 mT) were observed in irradiated ethylene hydrate. The decay of the 3-butenyl radicals was observed above 200 K with the activation energy of 51.9 +/- 4.4 kJ/mol. The obvious decay of ethyl radicals starts above 240 K that is close to the dissociation temperature of ethylene hydrate at atmospheric Pressure. The activation energy of the ethyl radical decay is estimated as 63.4 +/- 8.2 kJ/mol and nearly equal to the enthalpy change of ethylene hydrate into liquid water and gaseous ethylene. It is Suggested that the decay of ethyl radicals Would be caused by the hydrate dissociation and that ethylene hydrate dissociates into water (supercooled) and ethylene at 240-265 K.

    Electron spin resonance (ESR) studies have been performed to investigate radicals induced in ethane hydrate irradiated by gamma-rays at 77 K. Two ESR spectra are observed and identified as the induced ethyl radical (g = 2.0031 +/- 10.0005, A(alpha perpendicular to) = 2.2 +/- 0.1 mT, A(alpha parallel to) = 2.5 +/- 0.1 mT, A(beta) = 2.7 +/- 0.1 mT) and induced atomic hydrogen (g = 2.0026 +/- 0.0005, A = 50.5 +/- 0.1 mT). From the results of ESR analysis and gas mass spectroscopy, it is concluded that the ethyl radical decays into butane by dimerization in the first-order reaction in the temperature region of 250-265 K. The activation energy of the decay reaction is 73.1 +/- 16.3 kJ/mol, which is near the dissociation enthalpy change of ethane hydrate to liquid water and gaseous ethane. This finding implies that ethane hydrate does not dissociate into ice but supercooled water in the present temperature region, similar to the dissociation of methane hydrate in our previous study.

    The stability of methyl radicals formed in synthetic methane hydrate by gamma-ray irradiation at 77 K was studied at 200-273 K and 10 MPa. The methyl radicals decayed under these conditions, despite the stability of methane hydrate, and changed into other molecules that could not be detected by electron spin resonance (ESR). Decay products were investigated by gas cell infrared (IR) spectroscopy by measuring the decomposed gas from the gamma-irradiated methane hydrate. Only ethane molecules were detected from the irradiated sample, while these were absent in an unirradiated sample. The molar ratio of ethane to methane (C2H6/CH4) was 12 +/- 1 ppm, which did not contradict with that of methyl radical to methane (CH3./CH4) in the literature. Hence, most of the methyl radicals generated by irradiation were supposed to be transformed to ethane in methane hydrate.

    The thermal stability of gamma-ray-induced methyl radicals in methane hydrate was studied using the ESR method at atmospheric pressure and 210-260 K. The methyl radical decay proceeded with the second-order reaction, and ethane molecules were generated from the dimerization process. The methyl radical decay proceeds by two different temperature-dependent processes, that is, the respective activation energies of these processes are 20.0 +/- 1.6 kJ/mol for the lower temperature region of 210-230 K and 54.8 +/- 5.7 kJ/mol for the higher temperature region of 235-260 K. The former agrees well with the enthalpy change of methane hydrate dissociation into ice and gaseous methane, while the latter agrees well with the enthalpy change into liquid water and gaseous methane. The present findings reveal that methane hydrates dissociate into liquid (supercooled) water and gaseous methane in the temperature range of 235-260 K.

    Antarctic ice and rime ice after T-irradiation at 77 K were studied by electron spin resonance (ESR). The signal of nitrogen dioxide (NO2) was detected in both ices. The NO2 in the Antarctic ice, in particular, may be created from NO3- by reactions associated with intrinsic OH radicals. The detection limit of NO2 in solid samples was estimated to be similar to0.02 ppm with ESR. The analysis using ESR, in natural ice has a potential to trace environmental NO2. (C) 2004 Elsevier Ltd.

    Natural methane hydrate under deep ocean floor in Ocean Drilling Program (ODP) Leg 164 was studied by electron spin resonance (ESR) after gamma-ray irradiation. The methyl radical (g = 2.0024 +/- 0.0005, A = 2.3 +/- 0.1 mT) as well as an unidentified signal was observed. Although the parameters and the thermal stability. were very similar to those in a synthetic sample, the signal. intensity was about one eightieth of that in synthetic one because methane hydrate had partially changed to ice. ESR signal intensity of the methyl radical after gamma-ray irradiation could be used to estimate the amount of methane hydrate in a sample mixed with ice. (C) 2004 Published by Elsevier Ltd.

    A scanning electron spin resonance (ESR) microscope using a localized microwave field was redesigned to measure ESR spectra from 0 to 400 mT using electromagnets: Divalent copper ion (Cu2+) in copper sulfate pentahydrate (CuSO4.5H(2)O) was imaged, after the powdered samples were cemented in silicone rubber under a magnetic field. The ratio of the two signal intensities at g = 2.27 and 2.08 clearly indicates the orientation of the particles. This method can be used for mapping the local magnetic field and its direction.

    Synthetic methane hydrate irradiated by gamma-rays at 77 K has been measured by electron spin resonance (ESR). The quartet signal at g = 2.0029 +/- 0.0005 with the intensity ratio of approximately 1 : 3 : 3 : I and hyperfine coupling constant A = 2.3 +/- 0.1 mT was identified as the methyl radical (CH3..). The dose response of its signal intensities showed that the radicals were formed linearly up to 10 kGy with the G-value [the formation efficiency of radical pairs per 100 eV (16 aJ)] of 0.05. According to annealing experiments, the radical became unstable over 200 K, at which thermal dissociation of the hydrate had already started, but a very weak signal was detectable up to 270 K. The methyl radical thermally decayed following second-order kinetics with an activation energy of 0.26 +/- 0.02 eV (42 zJ). The existence of the signal at 270 K would be related to the extremely slow dissociation referred to as the self-preservation effect of the gas hydrate.

    Nitrate radical NO32- in calcitic evaporate was discovered in Antarctica. The distribution and formation of nitrate radical NO32- in the calcite have been studied by pulse and continuous-wave electron spin resonance. In samples that had been annealed to destroy the NO32-, regeneration of the radical by gamma-rays or UV light indicated that the radical was formed by UV light (with wavelengths less than 340 nm) from solar rays, not by environmental radiation. The nonuniform spatial distribution of the nitrate radical, which was deduced from high ratios of local spin density to total spin density, suggests that the nitrate impurity was introduced into the calcium carbonate after carbonate grain formation. Formation of the carbonate-containing nitrate requires the presence of high amounts of nitrate and a dry climate. Formation of the nitrate radical requires sample exposure to UV light. These conditions are satisfied in the environment of Antarctica.

    Free radicals ascribed to ascorbic acid (AscHZ), vitamin C, in the solid matrix of synthetic calcium carbonate have been studied using electron spin resonance (ESR) after UV irradiation. A new ESR signal with g-factors of g(parallel to) = 2.0024 and g(perpendicular to) = 2.0053 was found together with a broad singlet signal around g = 2.005 and a doublet signal at g = 2.0053 separated by 0.18 mT due to the ascorbyl radical (Asc(.-)). The molecular orbitals of Asc(.-) and two other types of ascorbyl radical (AscH(.-)) were calculated using the semi-empirical PM3 unrestricted Hartree-Fock (UHF) method, which indicated that the hyperfine splitting due to hydrogen bonded to one of the carbons in the pentagonal ring was dominant. The axial signal was ascribed to AscH(.-), while the doublet signal was ascribed to Asc(.-) in CaCO3. Possible pharmaceutical and nutritional applications of embedding unstable active molecules into the crystalline lattice of CaCO3 and a new nondestructive method for determination of vitamin C contents are discussed because the vitamin C has higher thermal stability in the carbonate than that in aqueous solution.

    A new unidentified electron center in gamma-ray-irradiated synthetic stishovite, a high-pressure polymorph of SiO2, was detected by X-band electron spin resonance. It has an anisotropic g-factor of orthorhombic symmetry, g(1) = 1.9764, g(2) = 1.9527 and g(3) = 1.9370. The signal intensity was saturated at a microwave power of 2 mW. Annealing experiments show that the center was annealed out around 280 K and unstable at room temperature. The center may be ascribed to a titanium electron center on the basis of a relatively large g-shift and a comparison with the paramagnetic centers in quartz.

    A new ESR isochrone dating for fracture age based on the effective annual dose for different grain sizes has been applied to quartz grains in fractured granite at the Nojima fault that moved during the earthquake in 1995 and in fault gouge at the Rokko fault in the vicinity. Incomplete resetting of ESR signals was observed for both samples collected at the ground surface. The fracture age of the quartz grains was obtained for the Rokko fault as (1.6 +/- 0.2) x 10(5) yr. At the Nojima fault there appears to be a considerable effect from previously-fractured surfaces in the newly-fractured material. The relation between the fracture age and the age of the fault movement is discussed. Copyright (C) 1996 Elsevier Science Ltd

    Electron spin resonance (ESR) of transition metal ions (Mn2+, Fe3+), radiation induced centres and pyrolytically formed radicals was studied to distinguish between burnt and unburnt soil. A testfire place and samples from an archaeological site were analyzed. The concentration of radiation induced centres decreases and pyrolytically formed radicals appear in a thermal annealing experiment. The spectral pattern of iron and manganese resonances changes during the heating process. These signals are useful to estimate temperature and atmosphere of the heating event. Chemithermoluminescence (CTL) of the soil was studied and could reveal its thermal history, too.

    A new isochrone method of electron spin resonance (ESR) dating has been proposed utilizing the different average dose rates of external radiation for different grain sizes due to the range of external alpha- and beta-rays., The equivalent doses (EDs) obtained by the additive dose method were plotted as a function of the external dose rate (D-ex) corrected for the grain sixes. The slope gives an ESR isochrone age since the fracture (T-trn) or the surface formation; the coordinate abscissa gives the internal dose (DmTfor) where D-in is the internal dose rate and T-for is the age of the mineral formation. The method has been applied to quartz (SiO2) grains in geological fault gouge at outcrops of the Rokko Fault giving T-fra=102,000 years and T-for of nearly zero for grains less than 100 mu m.
