Introduction: The main role of preservatives in eyedrops is to ensure sterility and microbiological integrity of the drug, and to facilitate the penetration of active compounds into the eye. However, several studies documented significant toxic effects induced by preservatives, especially on the ocular surface. Consequently, most of the ophthalmic medications became progressively available in preservative-free (PF) formulations. Areas covered: We analyzed pre-clinical and clinical studies on PF eyedrops with particular attention to common chronic diseases such as dry eye and glaucoma. We discussed about the pros and cons of using PF eyedrops, in terms of efficacy, safety, and social-economic aspects. Expert opinion: There are still unresolved issues that make hard for PF medications to definitively conquer the drug market. Despite robust pre-clinical evidences of less toxicity, the low number of randomized clinical trials does not permit to state that PF eyedrops have, in clinical practice, a similar efficacy or a higher safety compared to preserved forms. These aspects limit their use to chronic diseases requiring long-term therapies with multiple daily instillations, especially in the presence of concomitant ophthalmic diseases that expose to a risk of ocular surface worsening.

In an article, author is Nikitina, E., V, once mentioned the application of 367-21-5, Name: 3-Chloro-4-fluoroaniline, Name is 3-Chloro-4-fluoroaniline, molecular formula is C6H5ClFN, molecular weight is 145.562, MDL number is MFCD00007767, category is chlorides-buliding-blocks. Now introduce a scientific discovery about this category.

The synthesis of materials with a developed electrode surface of the electropositive component of the alloy and a significant near-surface layer was performed by anodic selective dissolution of copper alloys (Cu63-Zn37, Cu40-Zn37, Cu65-Ni35, Cu35-Ni65 and Cu50-Al50). The morphological and electro-chemical characteristics of the obtained electrode materials based on mesoporous copper demonstrate its prospects for catalysis substrate application, electrodeposition of materials with specified parameters, and for the low-wear anode base formation. The media was combination of lithium, sodium, potassium carbonates (30 : 30: 40 mol. %), as well as low-melting eutectic mixtures of alkali metal chlorides of various compositions (especially CsCl-KCl-LiCl (54.4: 15.3: 30.3 wt %) in the temperature range of 623-923 K. The object of the study was copper alloys such as copper-zinc, copper-aluminum, copper-nickel. Anodic selective dissolution was performed under the following electrolysis modes: galvanostatic and potentiostatic modes; rectangular polariza-tion; cyclic voltammetry. The values of geometric current densities were 100, 200, 300, 900, 1400 A/m(2). The applied anode potential was +0.1, +0.2 and + 0.5 V (from the open circuit potential of the material). The platinum reference electrode was used. The resulting surface structures were investigated using micro-and X-ray phase analysis. The composition of frozen melt samples after electrolysis completion was studied by atomic absorption analysis. The resulting surface structures were investigated using micro-and X-ray phase analysis. The influence of the following factors on the surface structure of the final anode product was studied and discussed: composition of the studied alloy (the amount of electronegative component in the alloy, as well as its nature); electrolyte composition (chloride and carbonate melt); temperature of selective dissolution (350, 500 and 650 degrees C) It was shown that it is possible to change the nature of the binary alloy dissolution by changing the kinetic parameters (electrolyte composition, temperature), and to obtain a mesoporous material with a developed surface, suitable for heterogeneous catalysis, structural design of electrochemical and elec-trical devices. a) the most perspective copper-based alloy for the formation of nanoporous and mesoporous materials in salt melts is brass Cu63-Zn37; b) the smallest average pore size had samples of brass Cu63-Zn37 in experiments with chloride melt; in galvanostatic mode the pore size was 500 nm (under given conditions -200 A/m(2), 350 degrees C); in potentiostatic mode -250 nm (+0.1 V, 500 degrees C). With the temperature decreasing it is possible to reduce this indicator by 1.5-3.0 times; c) the square-wave potentiometry method was used to form a developed near-surface layer in several stages; g) cyclic voltammetric curves were obtained, which can be used to prognosticate and describe the stages of the anode process; e) the potentials of open circuits were obtained for the studied samples; g) by dissolution of copper-aluminum alloy in galvanostatic mode was formed the nanofiber on the surface with thread size less than 20 nm. 2. The influence of the temperature, the nature of the second component of the alloy and the salt electrolyte (chloride) on the formation of the developed surface layer of the alloys under study was established: a) the increase in temperature leads to a decrease in the development of the surface layer; b) copper-nickel samples are depleting by copper due to the fact that copper is an electronegative component of the alloy in chloride melts, while the formation of developed surface layer enriched with nickel takes place; c) the increase in the content of the electronegative component leads to a decrease in the development of the surface. It was shown that it is possible to change the nature of the binary alloy dissolution by changing the kinetic parameters (electrolyte composition, temperature), and to obtain a mesoporous material with a developed surface, suitable for heterogeneous catalysis, structural design of electrochemical and elec-trical devices.

Dissolution of dihydrate gypsum and severe chemical corrosion are the principal causes of short working life of gypsum molds in slip casting technology. In this experiment, a new modification method was focused on the improvement of corrosion resistance on the premise of ensuring water absorption and mechanical strength. The effects of three soluble salts (barium chloride, sodium phosphate and sodium oxalate) on various properties of gypsum molds were evaluated using three different methods, which included solution mixing, immersing and coating. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to evaluate the phase transformations, structures and morphologies. Results revealed that immersing hardened sample into sodium oxalate solution effectively enhanced the corrosion resistance at the optimum concentration of 1.8 wt%. The water-saturated flexural strength and softness coefficient were increased by 36.7% and 22.2%, respectively. Calcium oxalate was produced by chemical reaction between dissolved Ca2+, SO42- and sodium oxalate. Calcium oxalate monohydrate (COM) was crystallized after water evaporation and the crystals accumulated on the outer surfaces of hardened pastes forming as waterproof film, which reduced the dissolution of dihydrate gypsum and further improved the corrosion resistance.

The removal of NOx (approximately 90% of which is NO) from flue gas is a crucial process for clean power generation from coal combustion. Oxidation of NO to NO2 followed by NO2 absorption using sorbents is considered to be a promising technology alternative to selective catalytic reduction (SCR). This study investigated the absorption of NO2 in flue gas by ethylene glycol (EG)-tetrabutylammonium bromide (TBAB) deep eutectic solvents (DESs) under a range of experimental conditions. The effects of experimental conditions including molar ratio of EG to TBAB, operating temperature, residence time, and the O-2 and steam partial pressure in the flue gas on the denitrification performance of EG-TBAB DESs were systematically analyzed. The concentrations of NO2 in the inlet and outlet were evaluated using a flue gas analyzer. The chemical structure changes of DESs after denitrification were characterized using Fourier transform infrared (FT-IR) spectroscopy. The obtained analysis signified that maximum denitrification efficiency and capacity were achieved at a EG/TBAB molar ratio of 5:1, 50 degrees C, and 6 s residence time. EG-TBAB DESs were able to maintain a stable denitrification performance after five absorption-desorption cycles. The results of quantum chemical calculation and H-1 NMR spectra of EG-TBAB DES show that bromide anions in the EG-TBAB DES maintained strong interactions with NO2 via hydrogen bonding, leading to increased NO2 adsorption. The presence of O-2 and steam in the flue gas improved the absorption of NO2 in EG-TBAB DESs due to chemical reactions and formation of nitrate.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 18997-19-8, Name is Chloromethyl pivalate, SMILES is CC(C)(C)C(OCCl)=O, in an article , author is Li, Xinzheng, once mentioned of 18997-19-8, Category: chlorides-buliding-blocks.

In this work, LED-based photocatalysis using mixed rutile and anatase phase TiO2 (P25) as the photocatalyst could effectively remove 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and methylisothiazolone (MIT) simultaneously, with removal efficiencies above 80% within 20 min. The photocatalytic degradation of both CMIT and MIT could be modeled using a pseudo-first-order rate equation. The photocatalytic degradation rates of CMIT and MIT under LED280 illumination were higher than under LED310 or LED360 illumination. At concentrations below 100 mg/L, the degradation rate of CMIT and MIT under LED illumination significantly increased with increasing catalyst dosage. Additionally, the effects of the chloride ion concentration, alkalinity and dissolved organic matter on the photocatalytic degradation reaction were also investigated. The .OH free radicals were determined to play the primary role in the photocatalytic degradation reaction, with a degradation contribution of >95%. The photocatalytic degradation of CMIT and MIT mainly occurred via oxidation, hydrolysis, and chain growth reactions. Finally, the possible photocatalytic degradation pathways of CMIT and MIT over LED/P25 are proposed.

In this study, a novel ternary Z-scheme Graphite-like Carbon Nitride (g-C3N4)/Silver (Ag)/Silver Phosphate (Ag3PO4) photocatalyst was designed and prepared using a two-step method (sodium chloride (NaCl) template-assisted strategy plus selective deposition). Its photocatalysts performance against removing 400 ppm of Nitric Oxides (NOx) was then investigated. We found 50 wt% g-C3N4/Ag/Ag3PO4 (AP-CN 2:1) catalyst removes up to 74% of NO in 90 min under the illumination of visible light (>420 nm), which is respectively 3.5 and 1.8 times higher than using g-C3N4 or Ag3PO4 , alone. This improved performance was attributed to the formation of Z-scheme g-C3N4/Ag/Ag3PO4 heterojunction, driven by the built-in electric field across the g-C3N4/Ag/Ag3PO4 interface. These separated the electron-hole but enhanced the original strong oxidation and reduction performance of related components. The superior performance is also attributed to the improved surface area, enhanced hydrophilicity (H2O2) and better visible-light-harvesting capability of the composite compound. More importantly, the AP-CN 2:1 sample maintained a NO removal rate of more than 73% even after four rounds of recycling. The photocatalytic oxidation removal mechanism was evaluated using the radical-capture experiments, electron spin resonance (ESR) and ion-exchange high-performance liquid chromatography (HPLC) analysis. The findings of this work offer a simple but effective design of a highly reactive and practical ternary Z-scheme heterojunction photocatalysts for the removal of toxic NO.

CLC-2 is a voltage-gated chloride channel that is widely expressed in mammalian tissues. In the central nervous system, CLC-2 appears in neurons and glia. Studies to define how this channel contributes to normal and pathophysiological function in the central nervous system raise questions that remain unresolved, in part due to the absence of precise pharmacological tools for modulating CLC-2 activity. Herein, we describe the development and optimization of AK-42, a specific small-molecule inhibitor of CLC-2 with nanomolar potency (IC50 = 17 +/- 1 nM). AK-42 displays unprecedented selectivity (>1,000-fold) over CLC-1, the closest CLC-2 homolog, and exhibits no off-target engagement against a panel of 61 common channels, receptors, and transporters expressed in brain tissue. Computational docking, validated by mutagenesis and kinetic studies, indicates that AK-42 binds to an extracellular vestibule above the channel pore. In electrophysiological recordings of mouse CA1 hippocampal pyramidal neurons, AK-42 acutely and reversibly inhibits CLC-2 currents; no effect on current is observed on brain slices taken from CLC-2 knockout mice. These results establish AK-42 as a powerful tool for investigating CLC-2 neurophysiology.

In this work deep eutectic solvent (DES), based on the mixture of choline chloride and lactic acid, were suggested as chitosan films plasticizers. The molecular structure and properties of films obtained using chitosan, with different degree of deacetylation and 0-80 wt.% DES content (omega(DES)), were studied by means of FTIR spectroscopy, SEM and AFM microscopy (films’ surface properties) together with optical characteristics, water vapor transmission rate (WVTR), water vapor permeability (WVP), tensile strength (TS) and elongation at break (E-b). Scanning electron micrographs revealed that all chitosan-DES films were smooth and uniform. DES significantly improves the film flexibility (E-b increases of ca. 160 % after incorporation of 80 wt.% DES), slightly decreases tensile strength and also improves antioxidative properties while simultaneously, increasing water vapor permeability (WVP). Films prepared in this study exhibit characteristics that qualify them for potential use as an active packaging material.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 2687-12-9, Name is Cinnamyl chloride, SMILES is ClCC=CC1=CC=CC=C1, in an article , author is Yu, Yong, once mentioned of 2687-12-9, Name: Cinnamyl chloride.

Application of recycled aggregate concrete (RAC) in engineering practice today remains relatively limited. One of the main reasons may be that the material’s durability has not been comprehensively understood. No sufficiently accurate formulas are available for predicting its resistance to chloride infiltration. This study was therefore designed to investigate the commonest factors influencing chloride penetration in RAC using mesoscale finite element models. The variables of interest were the geometric shape of coarse aggregate pieces, their location distribution, the volume content of recycled material, the relative strength of the old to new mortar, the adhering content of old mortar, the bonding property of interfacial transition zones (ITZs) and the mixing method used. After performing a series of numerical simulations, a genetic programming (GP) method was lastly adopted to establish an explicit expression for correlating the RAC’s effective chloride diffusivity with the identified key factors. Numerical results indicate that the RAC’s diffusion coefficient was negligibly influenced by the aggregate shape or the old ITZ property, and commonly grows with increasing water-to-cement ratio, the amount of old mortar, the new ITZ’s diffusivity as well with the replacing content of recycled aggregates. Equivalent mortar volume method can efficiently decrease the material’s chloride diffusivity, especially at low water-to-cement ratios in the attached mortar. Finally, the expression provided by the GP method can adequately predict all these trends and is very convenient for investigating the RAC’s chloride diffusion performance. (C) 2020 Elsevier Ltd.
