Validation of SMILES HCl profiles over a wide range from the stratosphere to the lower thermosphere

Hydrogen chloride (HCl) is the most abundant (more than 95 %) among inorganic chlorine compounds Cly in the upper stratosphere. The HCl molecule is observed to obtain long-term quantitative estimations of the total budget of the stratospheric chlorine compounds. In this study, we provided HCl vertical profiles at altitudes of 16-100 km using the Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) from space. The HCl vertical profile from the upper troposphere to the lower thermosphere is reported for the first time from SMILES observations; the data quality is quantified by comparison with other measurements and via theoretical error analysis. We used the SMILES level-2 research product version 3.0.0. The period of the SMILES HCl observation was from 12 October 2009 to 21 April 2010, and the latitude coverage was 40 degrees S-65 degrees N. The average HCl vertical profile showed an increase with altitude up to the stratopause (similar to 45 km), approximately constant values between the stratopause and the upper mesosphere (similar to 80 km), and a decrease from the mesopause to the lower thermosphere (similar to 100 km). This behavior was observed in all latitude regions and reproduced by the Whole Atmosphere Community Climate Model in the specified dynamics configuration (SD-WACCM). We compared the SMILES HCl vertical profiles in the stratosphere and lower mesosphere with HCl profiles from Microwave Limb Sounder (MLS) on the Aura satellite, as well as from the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) on SCISAT and the TErahertz and submillimeter LImb Sounder (TELIS) (balloon borne). The TELIS observations were performed using the superconductive limb emission technique, as used by SMILES. The globally averaged vertical HCl profiles of SMILES agreed well with those of MLS and ACE-FTS within 0.25 and 0.2 ppbv between 20 and 40 km (within 10% between 30 and 40 km; there is a larger discrepancy below 30 km), respectively. The SMILES HCl concentration was smaller than those of MLS and ACE-FTS as the altitude increased from 40 km, and the difference was approximately 0.4-0.5 ppbv (12 %-15 %) at 50-60 km. The difference between SMILES and TELIS HCl observations was about 0.3 ppbv in the polar winter region between 20 and 34 km, except near 26 km. SMILES HCl error sources that may cause discrepancies with the other observations are investigated by a theoretical error analysis. We calculated errors caused by the uncertainties of spectroscopic parameters, instrument functions, and atmospheric temperature profiles. The Jacobian for the temperature explains the negative bias of the SMILES HCl concentrations at 50-60 km.

Volume-regulated chloride channel regulates cell proliferation and is involved in the possible interaction between TMEM16A and LRRC8A in human metastatic oral squamous cell carcinoma cells

Objectives: Volume-regulated anion channels (VRACs), expressed in various cells, play an important role in cell volume regulation. Despite being physiologically defined almost half a century ago, only the molecular candidates of VRAC, TMEM16A, LRRC8A, and bestrophin-1 (BEST1), are known. Here, we aimed to explore the functional significance of VRAC in, HST-1, an oral squamous cell carcinoma (OSCC) cell line. Methods: Cell proliferation assays, RT-PCR, Western blot, and flow cytometry were used to estimate changes in gene expression and cell proliferation. Ion channel activity was recorded using the patch-clamp technique. Specific genes were knocked-down by siRNA assays. Results: VRAC, identified as a hypotonicity-induced current, was highly functional and associated with the proliferation of HST-1 cells but not of HaCaT (a normal keratinocyte) cells. The pharmacological profile of VRAC in HST-1 was similar to that reported previously. DCPIB, a specific VRAC inhibitor, completely inhibited VRAC and proliferation of HST-1 cells, eventually leading to apoptosis. VRAC in HST-1 was attenuated by the knockdown of TMEM16A and LRRC8A, while knockdown of BEST1 affected cell proliferation. In situ proximity ligation assay showed that TMEM16A and LRRC8A co-localized under isotonic conditions (300 mOsM) but were separated under hypotonic conditions (250 mOsM) on the plasma membrane. Conclusions: We have found that VRAC acts to regulate the proliferation of human metastatic OSCC cells and the composition of VRAC may involve in the interactions between TMEM16A and LRRC8A in HST-1 cells.

Electrocatalytic activity of metal-doped SnO2 for the decomposition of aqueous contaminants: Ta-SnO2 vs. Sb-SnO2

Sb-doped SnO2 (ATO) is one of the most widely used electrocatalyst anodes for the oxidation of water and wastewater. This study synthesizes Ta(V)-doped SnO2 (TTO) electrocatalysts as alternatives to ATO and systematically examines their electrocatalytic activity for the decomposition of organic substrates in various electrolyte solutions. The as-synthesized ITO exhibits the highest activity for the decomposition of phenol, N,N’-dimethyl-4-nitrosoaniline, and rhodamine-B at a Ta doping level of similar to 1%. The optimized TTO exhibits a higher activity for the decomposition of phenol than ATO in a chloride solution and a lower activity than ATO in a sulfate solution. Electron paramagnetic resonance analysis reveals that a relatively larger production of reactive oxygen species is achieved with ATO, whereas a larger production of reactive chlorine species is obtained with TTO. In the durability tests, both electrodes favor an alkaline condition (pH 12.8) over acidic and neutral conditions (pH 1.5 and 6.2, respectively), and Ta-SnO2 is less stable than Sh-SnO2 over the full pH range. Additionally, solid-state and electrochemical surface characterizations are carried out.

Studies on the self-aggregation, interfacial and thermodynamic properties of a surface active imidazolium-based ionic liquid in aqueous solution: Effects of salt and temperature

The influence of four sodium salts (NaCl, NaBr, Na2SO4, and Na3PO4) on the self-aggregation, interfacial, and thermodynamic properties of a surface active ionic liquid (1-hexadecyl-3-methylimidazolium chloride, C(16)MImCl) has been explored in aqueous solutions by conductometry, tensiometry, spectrofluorimetry, isothermal titration calorimetry and dynamic light scattering (DLS). Analyses of the critical micellar concentration (cmc) values indicate that the anions of the added salts promote the self-aggregation of C(16)MImCl in the order: Cl- < Br- < PO43-< SO42-. Dehydration of imidazolium head groups, in general, governs the process of micellization of aqueous C(16)MImCl in presence of the investigated salts within the investigated temperature range (298.15-318.15 K), while the melting of iceberg takes the leading role below 303.15 K for the C(16)MImCl-Na3PO4 system. The results indicate that addition of salt leads to a greater spontaneity of micellization, and that exothermicity prevails in these systems. Differential effect of the salts on the interfacial properties of C(16)MeImCl has been interpreted on the basis of the coupled influence of the electrostatic charge neutralization of surfactants at the interface, and the van der Wa-als repulsion of surfactant tails and electrostatic repulsion of surfactant head groups. C(16)MeImCl has been predicted to form spherical micelles in presence of varying amounts of NaCl, Na2SO4 and Na3PO4, while there occurs probably a transition in the micellar geometry from spherical to non-spherical shape when added NaBr concentration exceeds 0.01 mol.kg(-1). Fluorescence studies demonstrate that a combined quenching mechanism is operative for the quenching of pyrene fluorescence in the investigated C(16)MImCl-salt systems. Micellar aggregation numbers obtained from Steady State Fluorescence Quenching method have always been found be somewhat smaller than those estimated from Time Resolved Fluorescence Quenching method. The order of instability of the C(16)MImCl-micelles ascertained from Zeta potential measurements conform to what has been inferred from the cmc values. The hydrodynamic diameters of C(16)MImCl-micelles, obtained from DLS studies, have been found to increase with increasing salinity of the solutions. (C) 2020 Published by Elsevier B.V.

Controlled Growth of Large Grains in CH3NH3PbI3 Perovskite Films Mediated by an Intermediate Liquid Phase without an Antisolvent for Efficient Solar Cells

High-quality crystalline large grains with uniform morphologies of the perovskite films are particularly important for achieving stable, high-performance perovskite solar cells. Herein, an effective strategy to control the growth of large grains in the CH3NH3PbI3 perovskite films is demonstrated by modifying the perovskite film deposition process through forming an intermediate CH3NH3PbI3 center dot methylammonium chloride (MACl)center dot xCH(3)NH(2) liquid phase induced by CH3NH2 gas treatment in combination with a MACl additive without an antisolvent. By tuning the incorporation of the MACl additive to the perovskite precursor solution, this intermediate liquid phase enables the well-controlled growth of large grains up to 3 mu m, highly uniform morphology, and higher crystallinity in the final CH3NH3PbI3 perovskite films. The high-quality CH3NH3PbI3 film derived from the CH3NH3PbI3 center dot MACl center dot xCH(3)NH(2) phase leads to enhanced carrier lifetime and reduced charge-trap density and nonradiative recombination of the perovskite films. In addition, the defect healing and reduced grain boundaries also greatly improve the environmental stability in ambient air. The perovskite solar cells made via the CH3NH3PbI3 center dot MACl center dot xCH(3)NH(2) phase exhibit high power conversion efficiency of 18.4%, much higher than that of the perovskite solar cells made without MACl (15.8%).

Electrochemical immunosensor based on self-assembled gold nanorods for label-free and sensitive determination of Staphylococcus aureus

An electrochemical immunosensor based on self-assembled gold nanorods on glassy carbon electrode was developed for label-free and sensitive detection of Staphylococcus aureus (S. aureus). The gold nanorods were firstly assembled on the electrode surface by using poly-(diallyldimethylammonium chloride) (PDDA) and poly(styrenesulfonate) (PSS) as the linkers, followed by the functionlization of anti -S. aureus antibodies. The immobilized antibodies on self-assembled gold nanorods could efficiently capture S. aureus to the modified electrode by the specific immune reaction, which clearly blocked the electron transfer of electrochemical probes on the electrode surface due to the resistance of S. aureus. Atomic force microscopy and electrochemical impedance spectroscopy were used to verify the stepwise assembly of the immunosensor fabrication. The immunosensor could detect S. aureus in a linear range from 1.8 x 10(3) to 1.8 x 10(7) CFU mL(-1) with a low detection limit of 2.4 x 10(2) CFU mL(-1). Furthermore, the designed electrochemical immunosensor was successfully used to determine S. aureus in milk samples with acceptable results. The proposed immunosensor could be further expanded to sensitive detect other pathogens with the addition of specific antibodies.

Photon correlation spectroscopy in the fish salting process

The current study experimentally investigates the innovative photon correlation spectroscopy method application in fish salting process. The method is based on the Rayleigh scattering of light by a substance. The experiment aims to study the mass transfer laws, as well as technological and practical aspects of the fish salting process in brine without circulation. The paper focused on spatio-temporal dependence of the salt diffusion coefficients in the fish-brine system and their correlation with temperature, indicating that at a temperature close to 8 degrees C a diffusion-osmosis equilibrium occurs between the brine and the muscle tissue of fish. The salt diffusion rate was estimated, confirming the validity of the Crean’s frontal theory of salt mass transfer in muscle tissue of fish. Based on the Stokes-Einstein equation, it was shown that the dynamic viscosity of fish tissue fluid could be determined by changing the diffusion coefficient and the diffusing particles size. Practical applications Fish salting is an important preservation method in many countries. The present work seeks to investigate the salting of herring, as it is prone to ripening during this process. Excessive sodium chloride consumption is known to have a negative effect on humans. At the same time, the salt content in the product is interrelated with its preservation effect. In this regard, it is necessary to accurately calculate the specified salt concentration in the finished product for the optimal shelf life. Improvement of this process requires a better understanding of the mass-transfer mechanisms using modern investigation methods. Research focuses on spatio-temporal salt distribution in fish muscle tissue to arrive at clear conclusions, which can facilitate the improved production of salted fish and can be widely used in the food industry for processing and preserving fish or fish products.

Correlating scalants characteristic and air bubbling rate in submerged vacuum membrane distillation: A fouling control strategy

The feasibility of aeration for membrane scaling mitigation in submerged vacuum membrane distillation (S-VMD) system was evaluated. The effect of aeration rate in both intermittent and continuous modes were investigated. The flux decline rate due to fouling was reduced significantly with air bubbling. In the absence of aeration, larger salt crystals containing sodium chloride (NaCl) and magnesium sulphate (MgSO4) were deposited on the membrane. Continuous air bubbling at 30 LPM provides sufficient surface shear with noticeable reduction of sealants on the membrane surface. However, continuous bubbling at higher flow rate (60 LPM) caused rapid nucleation and smaller crystals on membrane that inferior the bubble scouring effect. Based on the theoretical analysis of hydrodynamic forces induced by the bubble flow, the net shear force generated by the bubbling at 60 LPM with velocity of 0.2 m/s (bubble size of 250-400 mu m) is not effective to remove particle that is smaller than 1.09 mu m. Continuous aeration at 30 LPM showed better cleaning efficiency and had almost constant specific energy consumption over long term operation. These results indicated that air bubbling is a feasible and effective method for alleviating membrane scaling in S-VMD system.

Methylammonium chloride as an interface modificator for planar-structure perovskite solar cells with a high open circuit voltage of 1.19V

Recently, the mixed-cation perovskites have been widely used in high-performance perovskite solar cells due to its excellent photoelectric properties. However, the mixed precursor-based method, particularly the complicated composition engineering, will cause phase transitional strain, low phase crystallinity and phase instability. Hence, interface modification engineering is very necessary to improve the phase crystallinity and stability, and then to optimize the performance of the photovoltaic devices. Herein, an interfacial engineering strategy is developed to enlarge the grain size and enhance the crystallinity of perovskite film through inserting a methylammonium chloride (MACl) layer between the SnO2 electron transport layer and perovskite layer. Therefore, the carrier extraction and transport are accelerated and the interfacial recombination is suppressed. Consequently, the optimal MACl-modified devices achieve a very high open circuit voltage of 1.19 V and a power conversion efficiency of 19.20% with the negligible hysteresis and enhanced stability in ambient condition, showing great superiority to the control devices without any modification.
