Has Stratospheric HCl in the Northern Hemisphere Been Increasing Since 2005?

Stratospheric hydrogen chloride (HCl) is the main stratospheric reservoir of chlorine, deriving from the decomposition of chlorine-containing source gases. Its trend has been used as a metric of ozone depletion or recovery. Using the latest satellite observations, it is found that the significant increase of Northern Hemisphere stratospheric HCl during 2010-2011 can mislead the trend of HCl in recent decades. In agreement with previous studies, HCl increased from 2005 to 2011; however, when the large increase of stratospheric HCl during 2010-2011 is removed, the increasing linear trend from 2005 to 2011 becomes weak and insignificant. In addition, the linear trend of Northern Hemisphere stratospheric HCl from 2005 to 2016 is also weak and insignificant. The significant increase of HCl during 2010-2011 is attributed to a strong northern polar vortex and a weakened residual circulation, which slowed down the transport of HCl between the low-mid latitudes and the high latitudes, leading to an accumulation of HCl in the middle latitudes of the stratosphere. In addition, a weakened residual circulation leads to enhance conversion of chlorine-containing source gases of different lifetimes to HCl, thus increasing the levels of HCl. Simulations by both chemistry transport and chemistry-climate models support the result. It is further found that the joint effect of a La Nina event, the west phase of the quasi-biennial oscillation and positive anomalies of sea surface temperature in the North Pacific is responsible for the strong northern polar vortex and a weakened residual circulation.

Chinese herbal medicine: Fighting SARS-CoV-2 infection on all fronts

Ethnopharmacological relevance: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes coronavirus disease 2019 (COVID-19), a highly pathogenic virus that has spread rapidly across the entire world. There is a critical need to develop safe and effective drugs, especially broad-spectrum antiviral and organ protection agents in order to treat and prevent this dangerous disease. It is possible that Chinese herbal medicine may play an essential role in the treatment of patients with SARS-CoV-2 infection. Aim of the review: We aim to review the use of Chinese herbal medicine in the treatment of COVID-19 both in vitro and in clinical practice. Our goal was to provide a better understanding of the potential therapeutic effects of Chinese herbal medicine and to establish a Chinese protocol for the treatment of COVID-19. Materials and methods: We systematically reviewed published research relating to traditional Chinese herbal medicines and the treatment of SARS-CoV-2 from inception to the 6th January 2021 by screening a range of digital databases (Web of Science, bioRxiv, medRxiv, China National Knowledge Infrastructure, X-MOL, Wanfang Data, Google Scholar, PubMed, Elsevier, and other resources) and public platforms relating to the management of clinical trials. We included the active ingredients of Chinese herbal medicines, monomer preparations, crude extracts, and formulas for the treatment of COVID-19. Results: In mainland China, a range of Chinese herbal medicines have been recognized as very promising anti-SARS-CoV-2 agents, including active ingredients (quercetagetin, osajin, tetrandrine, proscillaridin A, and dihydromyricetin), monomer preparations (xiyanping injection, matrine-sodium chloride injection, diammonium glycyrrhizinate enteric-coated capsules, and sodium aescinate injection), crude extracts (Scutellariae Radix extract and garlic essential oil), and formulas (Qingfei Paidu decoction, Lianhuaqingwen capsules, and Pudilan Xiaoyan oral liquid). All these agents have potential activity against SARS-CoV-2 and have attracted significant attention due to their activities both in vitro and in clinical practice. Conclusions: As a key component of the COVID-19 treatment regimen, Chinese herbal medicines have played an irreplaceable role in the treatment of SARS-CoV-2 infection. The Chinese protocol has already demonstrated clear clinical importance. The use of Chinese herbal medicines that are capable of inhibiting SARS-Cov-2 infection may help to address this immediate unmet clinical need and may be attractive to other countries that are also seeking new options for effective COVID-19 treatment. Our analyses suggest that countries outside of China should also consider protocols involving Chinese herbal medicines combat this fast-spreading viral infection.

Effects of mechanical stress and cathodic protection on the performance of a marine organic coating on mild steel

The separate and interactive effects of mechanical stress and cathodic protection on degradation behaviour of a marine epoxy-based organic coating on Q235 steel in 3.5% NaCl solution were investigated by employing electrochemical impedance spectroscopy technique. Results revealed that both tension stress (e.g., 120 and 200 MPa) and cathodic protection (e.g.,-0.8,-1.0 and-1.2 V with respect to a saturated silver/silver chloride electrode) could greatly deteriorate coating protective performance, including barrier properties, water uptake and diffusion as well as delaminated area, and meanwhile their harmful impacts could become more pronounced with the prolongation of immersion time. The interactive effect of the two factors on coating degradation was shown to be associated with their respective contribution. In addition, the degradation rate for the coating at the potentials of-0.8 and-1.0 V depended largely on the main reaction rate of oxygen reduction and hydrogen evolution, and the predominant control procedure of the two reactions could be reversed by the critical tension stress of 120 MPa.

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%).

Particulate Emission from Municipal Solid Waste Combustion: Effect of Si-Al-Based Additives for Its Mitigation

Particle emission is one of the major problems during municipal solid waste (MSW) combustion. This study investigated the particle emission distribution in flue gas and the effect of three types of Si/Al-based additives (kaolin, chabazite, and clinoptilolite) on reducing the emissions of particulate matter with PM10 during MSW combustion. The yields of ultrafine particle PM0.3, fine particle PM0.3-2.5, and coarse particle PM2.5-10 at the combustion temperature of 1100 degrees C were 1.58, 1.92, and 8.76 mg/g of MSW (dry basis), respectively. At 5% additive mass ratio, clinoptilolite showed the best particle reduction of 36.57% for PM0.3. Si/Al-based additives reduced particulate emissions by enhancing the conversion of alkali chlorides and sulfates to alkali silicate or aluminosilicate, which improves the melting point of alkali salts. A high Si/Al ratio enhanced the conversion to alkali sulfate in the vapor of volatile alkali salt through the competitive reaction of alkali metal salts and silicon aluminum oxide and, thus, inhibited the condensation and nucleation of alkali salt vapors to form ultrafine particles. Additives with a low Si/Al ratio produced more Na/K-Si-Al mineral binder on the surface of fine particles through the aluminosilicate formation, which promoted the agglomeration and coalescence of fine particles and improved the emission of coarse particles. The specific surface area of coarse particles was related to the agglomeration and coalescence ability of the particles. Further, it was also evident that the chabazite additive significantly increased the proportion of Na and K elements in PM1-2.3 and PM2.5-10 particles because of its high specific surface area and adsorption capacity.

Dispersion and vulcanization characteristics of nitrile rubber reinforced with N,N-dimethylacetamide/lithium chloride treated silica

N,N-Dimethylacetamide/lithium chloride (DMAc/LiCl) treated silica is used as a reinforcing filler in nitrile rubber (NBR). Effect of the treatment on aggregate morphology and dispersion of silica in the matrix is investigated using XPS, SEM, and AFM. Binding energy levels of O1s and Si2p electrons in DMAc/LiCl treated silica have shifted significantly from 532.49 to 530.98 eV and 103.19 to 101.33 eV respectively. SEM observations have revealed a reduction in the agglomerate size of silica-a desirable feature for realizing better processing properties of silica filled rubber compounds. Data from AFM observations have also shown better dispersion of DMAc/LiCl treated silica. Mooney viscosity of masterbatches, measured at 100 degrees C over a period of 7 days, has not exhibited any storage hardening which is an indication of easier processability. At 125 degrees C, Mooney data exhibited a reduction in scorch time as a function of DMAc/LiCl concentration. However, MDR data at 160 degrees C have not shown much changes in the scorch time while NBR with high nitrile content exhibited longer cure times. Higher crosslink density of vulcanizates indicate that DMAc/LiCl treatment of silica could effectively reduce filler-filler interactions and networking in silica filled rubber compounds thereby enabling mixing and processing operations energy efficient.

Chemically Durable Poly(phenylene-co-arylene ether) Multiblock Copolymer-Based Anion Exchange Membranes with Different Hydrophobic Moieties for Application in Fuel Cells

Quaternized multiblock poly(phenylene-co-arylene ether)s (QPPs) are synthesized from a pre-aminated monomer and a series of chlorine-terminated oligo(arylene-ethers) via a nickel coupling reaction. Their properties are investigated as anion exchange membranes with the goal of obtaining membranes with enhanced performance and durability for alkaline membrane fuel cell applications. Three different oligo(arylene ethers) were synthesized and introduced in the hydrophobic block of the polymer backbone to study its effect on the membrane properties. The chloride ion conductivity of the QPP membranes was significantly less dependent on the humidity compared to that of the commercial Fumatech membrane due to the well-defined hydrophilic-hydrophobic phase separation, as confirmed by TEM. An accelerated alkaline stability test indicated that the QPPs were more stable than the commercial Fumatech membrane up to 1700 h. The QPP-6F membrane shows an alkaline membrane fuel cell single-cell performance with a maximum power density of 534 mW cm(-2) at 70 degrees C.

Activation of peroxymonosulfate by calcined electroplating sludge for ofloxacin degradation

Developing cost-effective metal/metal oxides for peroxymonosulfate (PMS) activation remains a key issue in the sulfate radical based advanced oxidation process. In this work, electroplating sludge (ES), a transition metal-rich byproduct, was anaerobic calcined and characterized. Then, calcined electroplating sludge (CES) was applied as PMS activator for degradation of ofloxacin (OFL) and CES/PMS system exhibited a nearly 90% of OFL removal in 60 min. In addition, effect of CES, PMS, the initial pH and water constituents (chloride, bicarbonate, natural organic matter (NOM) and water backgrounds) on OFL degradation were systematically studied. Moreover, radical quenching tests and electron spin-resonance spectroscopy studies manifested that both SO4 center dot- and HO center dot were the ruling reactive oxygen species. X-ray photoelectron spectroscopy results of the fresh and used CES demonstrated that the PMS activation mainly occur in the transformation from Fe3+ (Cu2+) to Fe2+ (Cu+). Furthermore, liquid chromatography coupled with ion trap time-of-flight mass spectrometry was used to illustrate the possible degradation pathway of OFL. Moreover, CES showed excellent stability and reusability during reaction. This work points out a new way for value-added reuse for ES as a cost-efficient activator of PMS for organic contaminant removal. (C) 2020 Elsevier Ltd. All rights reserved.

Exploiting Deep Eutectic Solvents and Ionic Liquids for the Valorization of Chestnut Shell Waste

The full utilization of agricultural waste and its recycle into a new chain of value are of primary importance for the development of a sustainable and profitable agricultural industry. Chestnut shell waste (CSW) is an interesting case of study, whose valorization has been though partially investigated to date. This work aims at exploring the complete utilization of CSW, in terms of obtaining both value-added compounds and enriched cellulose and lignin fractions. The results were obtained via the unreported combined use of two classes of nonconventional organic solvents, namely natural deep eutectic solvents and bio-based ionic liquids (bio-ILs). At first, combinations of choline chloride (ChCl)-based DESs with an acid, a polyol, or a sugar as hydrogen bond donors were employed for the extraction of polyphenols from the CSW. The best performing system was found to be ChCl:oxalic acid dihydrate (ChCl:Oax2H(2)O). The extraction efficiencies of the DESs tested correlate well with the measured Kamlet-Taft a parameters. After polyphenol removal, the residual solid material was treated with a bio-IL [cholinium glycinate (ChGly)] for further separation of lignin and cellulose. The products obtained by the fractionation process were characterized by Fourier transform infrared spectroscopy and thermogravimetric analysis, which confirmed the separation of the residue into a lignin-rich material and a cellulose-rich material. The results obtained were further corroborated by a three parallel reaction model combined with the distributed activation energy model, which allowed for predicting the composition of the pristine CSW and of the ChCl:Oax2H(2)O treated CSW as well as the two fractions obtained after ChGly treatment. The recyclability of the best performing DES and the recovery of the bio-IL have also been proven, which make the whole process viable and amenable for large-scale applications.

Tannin-based thin-film composite membranes integrated with nitrogen-doped graphene quantum dots for butanol dehydration through pervaporation

A thin-film composite membrane was prepared through the interfacial polymerization of tannic acid (TA), a natural oligomer, and acyl chloride monomers – terephthaloyl chloride (TPC) or trimesoyl chloride (TMC). Thin-film nanocomposite (TFN) membranes were also prepared by loading a new class of carbon nanoparticles – nitrogen-doped graphene quantum dots (NGQDs). The composite membranes were characterized with ATR-FTIR, XPS, SEM and water contact angle. The TA-TMC membrane provided lower flux and better water permselectivity than those prepared with TA-TPC due to availability of more reactive acyl chloride. The concentrations of each reactant used, appropriate loading amount of NGQD and contact time between TA and acyl chloride monomers were all determined and investigated to separate 90/10 wt% n-butanol/water mixture at 25 degrees C. The TA-TMC was found to have higher surface hydrophilicity due to more hydroxyl groups present. The incorporation of 50 ppm NGQD during the interfacial polymerization enhanced the pervaporation performance by providing additional hydmphilicity and mass transfer resistance to larger permeating molecule. The TA(0.075)-TMC0.4-NGQD(50) membrane at 3-min contact time had a total flux of 1100 g m(-2) h(-1) and a water concentration in permeate of 97.1 wt% compared to TA(0.075)-TPC0.4-NGQD(50) membrane with 2196 g m(-2) h(-1) and 93.2 wt% in separating 90/10 wt% n-butanol/water mixture at 25 degrees C. The water permselectivity was also found to be more efficient for isobutanol/water mixtures due to the sterically hindered structure of the alcohol. Furthermore, the TA(0.075)-TMC0.4-NGQD(50) membrane was also tested to separate all butanol isomer/water mixtures at 25 degrees C showing better separation performance for sterically hindered or branched butanol isomer. The membrane fabricated herein shows the potential use of cheap and natural oligomer (TA) to produce thin-film composite membranes that provided enough barrier to separate butanol from water through pervaporation.
