Sustainable water management is key to achieving sustainable development goals. Increasing water consumption prompts industrial plants to implement water conservation projects (WCPs) and improve the utilization efficiency of water resources. In this paper, we develop an integrated graphical method for the implementation of water conservation projects by considering both water-saving targets and investment costs with or without government subsidies. First, cost-benefit analysis for different projects is carried out. The unit water saving cost diagram is employed to rank the priority of implementation of each project. Then, the project combination that meets the expected water-saving goal is determined via water-saving pinch analysis. Finally, the water conservation potential and cost-benefit of the optimal project combination are estimated using the marginal cost curve diagram. Two scenarios are considered for the proposed graphical approach: with and without government subsidies. A chlor-alkali/polyvinyl chloride complex is used as an illustrative case study. The results indicate the proposed method can be used to screen out the feasible projects under the constraints of water-saving target and financial fund. (C) 2020 Elsevier Ltd. All rights reserved.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1642-81-5, in my other articles.

Following the plenty of research work on solving the issue of the popular and promising perovskite solar cells, this article is focused on methylammonium lead iodide (MAPbI(3)) and the alternative element which can perform as efficiently as lead does. Here, not only the different concentrations of the substitute element are investigated, but also higher stable perovskite is introduced as well. Several characterization techniques are used to assure the validity of the results. The large alkali metal potassium (K) and the transition metal zinc (Zn) are studied side by side. The results are interesting when the 5% concentration of the KI alloyed MAPbI(3) shows considerable transport properties like 54 nm diffusion length, 245 x 10(-9 )Sm(-1) photo-conductivity, and significant majority and minority carrier mobility-lifetime product as compared to MAPbI(3) but it becomes more interesting when after 60 days the 5% concentration of the aged ZnCl2 alloyed MAPbI(3) turns into a leading element of this research by showing high stability among of all. The morphology investigations show both perovskite materials achieve large islands which are desired morphology in perovskite materials as well. (C) 2020 Published by Elsevier B.V.

Background The use of cisplatin is limited by the development of nephrotoxicity, with an incidence approaching 30%. It is unclear if a risk prediction score can effectively predict the development of nephrotoxicity throughout all cycles of cisplatin therapy among outpatients. Methods Retrospective, observational study evaluating adult patients receiving cisplatin in outpatient infusion centers from January 2009 to November 2019 (n = 186). A risk prediction score consisting of patient age, cisplatin dose, hypertension, and serum albumin was calculated to predict the risk of cisplatin-induced nephrotoxicity. Results The incidence of nephrotoxicity was 23.7% overall, with 8.1% of patients developing cisplatin-induced nephrotoxicity after the first dose. Patients who developed nephrotoxicity had a higher mean risk prediction score compared to patients who did not have nephrotoxicity (4.0 +/- 2.0 versus 2.9 +/- 2.1, p = 0.004, respectively). Multivariate logistic regression demonstrated each 1-point increase in the risk prediction score increased the odds of nephrotoxicity by 26.5% (OR: 1.27; 95% CI: 1.02-1.57, p = 0.034). Presence of diabetes mellitus increased the odds of cisplatin-induced nephrotoxicity (OR 3.66; 95% CI: 1.43-9.33, p = 0.007), whereas receipt of greater than or equal to 1 liter of 0.9% sodium chloride was protective, decreasing the odds of developing nephrotoxicity by 25%. Conclusion By identifying patients at the highest risk of cisplatin-induced nephrotoxicity, providers can individualize risk reduction strategies. The use of a risk prediction model successfully predicted the risk of nephrotoxicity throughout all cycles of cisplatin in an outpatient setting.

Ethnopharmacological relevance: Sesame (Sesamum indicum, L., Family: Pedaliaceae) is a notable folk medicine in Middle East, Asia and Africa. Many traditional and pharmacological studies have documented the unique nature of sesame oil (SO). SO has been reported to have many pharmacological effects related to the anti-inflammatory and antioxidant capacity of its components. Neuroinflammation and oxidative stress have been the predominant pathogenic events in Alzheimer’s disease (AD) which is one of the most common neurodegenerative diseases. Aim of study: we aimed to explore the neuroprotective effect and the probable mechanisms of SO against aluminium chloride (AlCl3)-induced AD symptoms. Materials and methods: Rats were treated daily with AlCl3 (100 mg/kg/i.p.) either alone or with SO (two different doses) for six weeks. Behavioral (Open-field and Morris water maze tests), histopathological, and biochemical examinations were used to evaluate the neuroprotective effect and the underlying mechanisms of SO against AlCl3-induced AD symptoms. Results: Our results indicated that SO significantly improved learning and memory impairments induced by AlCl3. Indeed, SO treatment significantly restored the elevated level of acetylcholinesterase (AChE) and amyloid beta (A beta) overexpression. Moreover, AlCl3 treatment afforded histopathological changes, increase the expression of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) in addition to mitigation of oxidative stress status in the brain. SO abolished all these abnormalities. Meanwhile, AlCl3 induced activation of p38 mitogenactivated protein kinase (p38MAPK) and decreased brain-derived neurotrophic factor (BDNF) which were inhibited by SO. Furthermore, SO administration modulated the expression of the peroxisome proliferatoractivated receptor gamma (PPAR-gamma) and nuclear factor kappa B (NF-kappa B). Conclusions: In conclusion, the neuroprotective effect of SO involved the modulation of different mechanisms targeting oxidative stress, neuroinflammation, and cognitive functions. SO may modulate different molecular targets involved in AD pathogenesis by alterations of NF-kappa B/p38MAPK/BDNF/PPAR-gamma signalling and this may be attributed to the synergistic effect of their active components.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Chen, Hao, once mentioned the application of 10147-36-1, Name is Propane-1-sulfonyl chloride, molecular formula is C3H7ClO2S, molecular weight is 142.6045, MDL number is MFCD00007462, category is chlorides-buliding-blocks. Now introduce a scientific discovery about this category, Category: chlorides-buliding-blocks.

Imidazolium/pyridinium-based trisiloxane surfactants containing a phenyl or vinyl group in the hydrophobic siloxane chain, bis-(vinyldimethylsiloxy)methylsilylpropyl-pyridinium chloride (Vi-Si(3)pyrCl), bis-(vinyldimethylsiloxy)methylsilylpropyl-imidazolium chloride (Vi-Si(3)minCl), and bis(phenyldimethylsiloxy)methylsilylpropylimidazolium chloride (Ph-Si-3 minCl), were synthesized and confirmed by nuclear magnetic resonance (NMR) (H-1, (13) C, and Si-29 NMR), mass spectrometry, and Fourier transform infrared spectrometry. The effect of the phenyl/vinyl group on their micellization behavior was studied by surface tension, electric conductivity, dynamic light scattering, 2D nuclear Overhauser effect spectroscopy (NOESY) NMR, and transmission electron microscopy. Owing to the hydrophobicity of the siloxane groups and cationic head groups, the critical micelle concentration (cmc) values follow the order Ph-Si(3)minCl < Vi-Si(3)pyrCl < Vi-Si(3)minCl < Si(3)pyrCl. Ph-Si(3)minCl has a larger gamma(cmc) value, resulting from the introduction of the phenyldimethy siloxy unit (pi-pi stacking interaction). The beta values of Vi-Si(3)minCl and Ph-Si(3)minCl increase with the increase in temperature, which is attributed to the intermolecular interaction which hinders the association of Cl- with the imidazolium ring and confirmed by 2D NOESY NMR. In aqueous solutions, the investigated cationic trisiloxane surfactants can self-assemble into spherical aggregates. Do you like my blog?

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.

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.
