Ab Initio Study of Hydrogen Storage in Hydrogen Hydrate Clathrates

Recently, for the first time a hydrate clathrate was discovered with hydrogen. Aside from the great technological promise that is inherent in storing hydrogen at high density at modest pressures, there is great scientificinterest as this would constitute the first hydrate clathrate with multiple species per cage. The multiple cage occupancy is controversial, and reproducibility of the experiments has been questioned. Therefore, in this study we try to illucidate the stability of the hydrogen hydrate clathrate, and determine the thermodynamically most favored cage occupancy using highly accurate ab initio computer simulations.
Willingness-to-pay for solid waste management service attributes: Kolkata Municipal Corporation area, India, as a case study

This paper examines public perceptions towards qualitative and quantitative attributes of a solid waste management (SWM) system in terms of willingness-to-pay (WTP) values. A stated choice (SC) survey instrument was designed and data was collected from residents in the Kolkata Municipal Corporation (KMC) of West Bengal, India. Respondents were approached randomly and face-to-face interviews were carried out. The behavioural data collected from residents are analysed by developing a standard multinomial logit (MNL) model and model coefficients are used for calculating the WTP values. Using the WTP values, the total disutility of SWM system is expressed in the form of generalised cost (GC).
The Effectiveness of Mindfulness-based Cognitive Therapy on Sleep Quality of Students with Social Anxiety Disorder

Background and Objective: Anxiety disorders are usually accompanied with sleep disorders. Since limited studies have focused on the effectiveness of mindfulness-based cognitive therapy (MBCT) on anxiety-related problems such as sleep disorders, the current research was conducted to investigate the effectiveness of this intervention on sleep problems. Materials and Methods: This study was a clinical trial with control and treatment groups. The sample consisted of 24 university students diagnosed with social anxiety disorder (SAD). Social Interaction Anxiety Scale (SIAS) and Pitts-burgh Sleep Quality Index (PSQI) were used to assess the dependent variables. There were measurements during pre-test, post-test, and follow-up stages. Results: The treatment could significantly improve the anxiety and sleeping problems in patients with social anxiety. Assessing the aspects of sleep quality showed that the intervention could improve the subjective aspects, latency, dis-turbance, and daily dysfunctions of sleep effectively; however, there was no significant effect on the duration of sleep, taking sleep medications, or sleep efficiency. Conclusion: Mindfulness treatment could be used for improving sleep quality in patients with social anxiety. This treatment could also improve the aspects of sleep quality which are related to sleep threshold.
Chlorophenyl pendant decorated graphene sheet as a potential antimicrobial agent: synthesis and characterization

Facile synthesis of a chlorophenyl decorated graphene (CBG) sheet synthesized by a solvent free green diazotization technique is reported here. The functionalization of the material was supported by various characterization techniques including Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), infrared spectroscopy (IR) and thermal analysis. About 15 percent grafting, as determined by XPS and IR spectroscopy, could be achieved under the conditions employed. The CBG sheet was applied for the first time as a potential antibacterial agent on Gram negative bacteria Escherichia coli and Gram positive bacteria Staphylococcus aureus. The antibacterial character was quantified using the MacFarland number technique whereby the volumetric number density of colony forming units was determined. It was also quantified by a Kirby–Bauer test, where the zone formed due to mortality of bacteria caused by chlorine groups attached to the graphene was estimated by a mathematical model. Based on the zone of inhibition created, CBG was found to be more than twice as effective as unmodified graphene and graphene oxide. The synthesis promises to open up a new avenue for the development of chemically converted graphene based antimicrobial agents.
Enhanced airway hyperresponsiveness in asthmatic children and mice with A(H1N1)pdm09 infection

Severe asthma exacerbation is an important comorbidity of the 2009 HIN1 pandemic (A(H1N1)pdm09) in asthmatic patients. However, the mechanisms underlying severe asthma exacerbation remain unknown. In this study, airway hyperresponsiveness (AHR) was measured in pediatric asthma patients infected with A(H1N1)pdm09. We also evaluated AHR in asthmatic mice with A(H1N1)pdm09 infection and those with seasonal influenza for comparison.
Nonlinear effects in the positive column of a strongly modulated mercury-rare gas discharge

The properties of the positive column of strongly modulated low-pressure gas discharges in mercury-rare gas mixtures have been studied, both experimentally and theoretically. The current was modulated sinusoidally with a modulation depth of 50%. Calculations have shown that in a limited frequency range nonlinearities in the system have an effect on the time-averaged electron temperature, electron density and excited atom density, and on their waveforms. This behaviour was confirmed by experiments, in which the electron temperature and density were measured by means of microwave techniques and the excited Hg atom densities by measuring the optical absorption and emission. For higher modulation depths differences occur between the results of the calculations and experiments. These discrepancies were found to be more pronounced in pulsed discharges, and are ascribed to changes in the high-energy tail of the electron velocity distribution function.

Order and disorder in sodium silicate glasses and melts at 10 GPa

We report experimental evidence, in conjunction with quantum chemical calculation, supporting chemical ordering among network polyhedra (e.g. [5]Si and [6]Si) in sodium silicate glasses quenched from melts at 10 GPa by using 17O 3QMAS (triple quantum magic angle spinning) NMR, which resolves new oxygen sites at high pressure, including [5,6]Si‐O‐[4]Si and Na‐O‐[5,6]Si. The distribution of network polyhedra at 10 GPa, a controlling factor for transport and melting processes in the mantle, is not completely random but favors formation of oxygen linking dissimilar Si pairs such as [5,6]Si‐O‐[4]Si. The presence of non‐bridging oxygens (NBOs) in highly coordinated units at 10 GPa, Na‐O‐[5,6]Si, indicates that the formation of highly coordinated Si can also occur at initially depolymerized silicon tetrahedra such as Q3 or Q2. The methods and results given here yield improved prospects for understanding melt structures at high pressure and the atomistic origin of magmatic processes in the Earth's interior.
Electrochemical properties of electrochemically polymerized polypyrrole film in the dark and under light irradiation.

Polypyrrole films prepared on Pt or SnO2 through electrochemical oxidative polymerization of pyrrole were characterized with respect to electroconductivity by photoelectrochemical measurements. Redox reactions of solution species such as methyl viologen, hydroquinone, oxygen, Cu2+, I−, and Br− occur on these electroconductive films. Light excitation of the film with wavelengths shorter than 550 nm results in observable cathodic photocurrent at the potential region more negative than 0.0 V vs. Ag. The polypyrrole film is a p-type semiconductor with a bandgap energy of ca. 2.2 eV and is stable during redox reactions.

The commonest cause was alcohol induced type, 52(65%) followed by gall stone pancreatitis 17(21%). Diet, alcohol intake or gender did not corelate with severity of pancreatitis. Elderly patients with high BMI are more prone to complications.
Carbon nanotubes and gas adsorption

We report results on the physisorption of N2 and H2 at low temperatures by single-walled carbon nanotubes (SWNTs) produced by the arc discharge method. We characterized (SEM, TEM, and HRTEM characterizations) two batches of sample, raw collaret and chemically treated SWNTs, in order to determine the best nanotube-containing sample for gas storage. Treatments and the effectiveness of the chemical acid treatments are discussed. Adsorption measurements of N2 on SWNTs allow us to obtain the specific surface area and pore size distribution. Acid treatments used to purify and open (by cutting) nanotubes decreased the surface area as a result of material compaction. Measurements of H2 adsorption were performed in order to evaluate the adsorption capacity of the nanotubes at 133K and below 2 bar. We found up to H:C atomic ratio=0.35, ie. 2.4 wt% of adsorbed hydrogen by gram of sample for our raw material.

Field Evaluation of the Differential TEOM Monitor for Continuous PM2.5 Mass Concentrations Special Issue of Aerosol Science and Technology on Findings from the Fine Particulate Matter Supersites Program

The performance of a prototype differential TEOM monitor (Rupprecht and Patashnick Co., NY) and its ability to measure the “actual” ambient near-continuous PM-2.5 mass in an area often high in semivolatile particulate matter has been evaluated. Measurements were made within a mobile particle instrumentation trailer (PIU) located in Claremont, CA—a “receptor” site in the Los Angeles Basin. The Differential TEOM monitor has been developed to directly measure ambient PM mass concentrations while accounting for collection artifacts, including loss of semivolatile aerosols and temperature changes. The Differential TEOM monitors used in this study were self-referencing, providing mass concentration measurements at 5 min intervals. To reference the semicontinuous mass measured by the Differential TEOM monitor, its 24 h time-integrated mass concentrations were compared to those determined by collocated filter-based samplers, i.e., MOUDI (Model 110) and Partisol (Model 2025). A HEADS was used to evaluate ammonium nitrate losses from the time-integrated samplers. The results show that PM-2.5 mass measurements using the Differential TEOM monitor are consistent with those of the MOUDI and Partisol, while differences can be generally explained by loss of ammonium nitrate from the reference samplers. The field results also demonstrate the ability of the Differential TEOM monitor to track adsorption and desorption processes from its sample filter. Although adsorption and evaporation can be dynamic processes, and difficult to estimate, the results of this study also suggest that the Differential TEOM monitor provides a very good estimate of the “actual” ambient particulate mass present on a near-continuous basis.

Synthesis and characterisation of the first organotin complex of piroxicam. An extended network system via non-hydrogen, hydrogen bonding linkages and C–H· · ·π contacts

The organotin complex, [SnBu2(pir)]n, of the potent and widely used anti-inflammatory drug piroxicam, H2pir, was obtained and a crystal structure determination showed that in this complex the ligand is doubly deprotonated at the oxygen and amide nitrogen atoms. There are two similar molecules in the asymmetric unit. The isolated molecules of Sn(1) or Sn(2) are arranged in polymers in a head to tail fashion with a stacking of alternate parallel chains. Extended networks of Sn–O–Sn, C–H· · ·O and C–H· · ·π contacts lead to aggregation and a supramolecular assembly. Real concentration protonation constants for the zwitterionic form (pyridyl group) and the protonated piroxicam (enolic group) were determined spectrophotometrically in pure aqueous solutions of constant ionic strength. It is the first example where piroxicam is proved to act as a doubly deprotonated tridentate ligand.

Passivation of double-positioning twin boundaries in CdTe

We present density-functional total-energy calculations to investigate the passivation effects of impurity elements such as Br, Cl, S, O, H, and Na on double-positioning twin boundaries in CdTe. We find that Br, Cl, S, and O atoms present passivation effects on the boundaries with different degrees, whereas H and Na do not passivate the boundaries. Of all these impurities, Cl atoms present the best passivation effects on the double-positioning twin boundaries. The superior passivation effects are realized by either terminating the Cd atoms with dangling bonds, or substituting the Te atoms with dangling bonds in the double-positioning twin boundaries in CdTe by Cl atoms.
