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, 50-30-6, Name is 2,6-Dichlorobenzoic acid, SMILES is O=C(O)C1=C(Cl)C=CC=C1Cl, in an article , author is Liu, Yun, once mentioned of 50-30-6, Name: 2,6-Dichlorobenzoic acid.

Persistent anion binding in a wide range of solution environments is a key challenge that continues to motivate and demand new strategies in synthetic receptor design. Though strong binding in low-polarity solvents has become routine, our ability to maintain high affinities in high-polarity solvents has not yet reached the standard set by nature. Anions are bound and transported regularly in aqueous environments by proteins that use secondary and tertiary structure to isolate anion binding sites from water. Inspired by this principle of solvent exclusion, we created a sequence-defined foldameric capsule whose global minimum conformation displays a helical folded state and is preorganized for 1:1 anion complexation. The high stability of the folded geometry and its ability to exclude solvent were supported by solid-state and solution phase studies. This capsule then withstood a 4-fold increase in solvent dielectric constant (epsilon(r)) from dichloromethane (9) to acetonitrile (36) while maintaining a high and solvent-independent affinity of 10(5) M-1; Delta G similar to 28 kJ mol(-1). This behavior is unusual. More typical of solvent-dependent behavior, Cl- affinities were seen to plummet in control compounds, such as aryl-triazole macrocycles and pentads, with their solvent-exposed binding cavities susceptible to dielectric screening. Finally, dimethyl sulfoxide denatures the foldamer by putative solvent binding, which then lowers the foldamer’s Cl- affinity to normal levels. The design of this capsule demonstrates a new prototype for the development of potent receptors that can operate in polar solvents and has the potential to help manage hydrophilic anions present in the hydrosphere and biosphere.

Biocides such as quaternary ammonium compounds (QACs) are potentially important contributors towards bacterial antimicrobial resistance development, however, their contributions are unclear due to a lack of internationally recognized biocide testing standards. Methods to detect QAC tolerance are limited to laborious traditional antimicrobial susceptibility testing (AST) methods. Here, we developed a rapid fluorescent dye-based membrane impermeant assay (RFDMIA) to discriminate QAC susceptibility among Gram-negative Enterobacterales and Pseudomonadales species. RFDMIA uses a membrane impermeant fluorescent dye, propidium iodide, in a 30-min 96-well fluorescent microplate-based assay where cell suspensions are exposed to increasing QAC concentrations. Our results demonstrate that RFDMIA can discriminate between QAC-susceptible and QAC-adapted Escherichia coli tolerant phenotypes and predict benzalkonium and cetrimide tolerance in all species tested except for intrinsically fluorescent Pseudomonas aeruginosa. RFDMIA identified a close association to minimum inhibitory concentration values determined by broth microdilution AST and increasing fluorescent dye emission values. RFDMIA emission values and scanning electron microscopy results also suggest that CET-adapted E. coli isolates have a CET dependence, where cells require sub-inhibitory CET concentrations to maintain bacilliform cell integrity. Overall, this study generates a new, rapid, sensitive fluorescent assay capable of detecting QAC-susceptible Gram-negative bacteria phenotypes and cell membrane perturbations.

This investigation deals with the design and synthesis of new derivatives of pyrrole consisting of modifying atoms of chlorine, amide, and 1,3-oxazole fragments. These compounds can be interesting in the context of research of new antimicrobial agents. Ethyl 5-chloro-4-formyl-1H-pyrrole-3-carboxylates were used as a key substrate for further transformation into target compounds. This process was realized as a direct transformation of an aldehyde fragment into a 1,3-oxazole cycle by van Leusen’s reaction followed by hydrolysis of an ester group, which finally converted a reactant into the corresponding pyrrole-3-carboxylic acid. This acid has been found to be an efficient construction block for the further development of antimicrobial agents. The preparative potential of these compounds has been verified by way of their transformation into a series of carbamides through consecutive reactions with thionyl chloride and alkyl-, aryl, and heterylamines under mild reaction conditions. According to bio screening results, the following two compounds have been chosen as those exhibiting a high anti-staphylococcus activity: 1-butyl-5-chloro-2-methyl-4-(1,3-oxazol-5-yl)-N-[(1,3-thiazol-2-yl]-1H-pyrrole-3-carboxamide and 1-butyl-5-chloro-N-[(3-dimethylaminosulfonyl)phenyl]-2-methyl-4-(1,3-oxazol-5-yl)-1H-pyrrole-3-carboxamide (MIC = 7.8 mu g/ml), while another one – 5-chloro-N-(4-chlorophenyl)-4-(1,3-oxazol-5-yl)-2-phenyl-1-propyl-1H-pyrrole-3-carboxamide was selected as a compound exhibiting high antifungal activity (MIC = 7.8 mu g/ml) against the reference strains Candida albicans ATCC 885/653 and Aspergillus niger K9.

Silver nanowires were successfully prepared by polyol method using silver nitrate as silver source, ethylene glycol as solvent and reducing agent, and ferric chloride as nucleating agent and polyvinylpyrrolidone (PVP) as structure directing agent and protective agent. The obtained silver nanowires were mixed with Kraft pulp fibers and bacterial cellulose to prepare conductive paper via simple filtration process. The results indicated that the size of silver nanowires can be regulated by the dosage of ferric chloride used. At optimal dosage of FeCl3, the prepared silver nanowires can reach 20 mu m length, 100 nm width, and 200 of width/diameter ratio. The adding of bacterial cellulose in preparing the conductive paper greatly enhanced the retention ratio of silver nanowires as well as the stress and strain of the conductive paper. The stress and strain of the paper with bacterial cellulose were increased by 60% and 7%, respectively, compared with that of the paper without bacterial cellulose. The maximum retention ratio and the highest recovery ratio of silver nanowires in conductive paper reached 94% and 75%, respectively. The resistance of as-prepared conductive paper was only 0.9 omega. In conductive paper, the silver nanowires attached to the paper-based materials with cellulose fibers as the substrate, which achieved the electrical conductivity of paper-based materials. This conductive paper can be applied as antistatic, antibacterial packaging and conductive material.

This study presents the evaluation of an air conditioning system with enthalpy recovery for space heating and air humidification. Desiccant assisted air conditioning is potentially beneficial against other air conditioning processes in terms of air humidification, counteracting dry indoor air conditions during winter. Furthermore, the overall process can be operated efficiently relying on renewable energy sources. The objective of this work is to investigate a geothermal and desiccant assisted system for different system configurations experimentally and numerically during winter operation. The experimental investigation focuses on differences in system performance for two desiccant materials, lithium chloride and silica gel. Experimental results show that moisture recovery relying on a desiccant wheel with silica gel is beneficial against lithium chloride. An average moisture recovery efficiency of 0.83 was achieved for silica gel. Thermal comfort was maintained on a high level throughout the winter seasons investigated. Based on component and system simulation models, system performance is shown for different boundary conditions during winter requiring space heating and humidification to ensure comfortable indoor air conditions. The simulation results show a reduction in primary energy demand for heat supply by up to 54% by using a high efficient ground-coupled heat pump without backup system. (C) 2020 The Author(s).

Interactions Between Hydrated Cerium(III) Cations and Carboxylates in an Aqueous Solution: Anomalously Strong Complex Formation with Diglycolate, Suggesting a Chelate Effect

Interactions between hydrated Ce3+ and various carboxylates are of fundamental interest. Anomalously strong interactions with Ce3+ occur when diglycolic acid (DGA) is added into a Ce3+ aqueous solution, unlike various other carboxylic acids. Herein, the complex-formation constants of Ce3+ with these acids are evaluated via absorption and emission spectra. Hydrated Ce3+ emits fluorescence with unity quantum yield; however, addition of various carboxylates statically quenches the fluorescence when Ce3+-carboxylate complexes form because the fluorescence lifetime is constant irrespective of the carboxylate concentration. In the observed static quenching, the complex-formation constants obtained from the absorption and emission spectra (K-abs and K-em) agree well. The binding of Ce3+ by the conjugate Lewis bases, i.e., carboxylates, is approximately inversely proportional to the pH. Adding DGA into the system also statically quenches the fluorescence, but far more efficiently, even in a much weaker solution. We rigorously deduce K-abs and K-em of Ce3+ with DGA without any approximation using comparable concentrations. Careful fittings provide equivalent K-em and K-abs values, and by varying the pH and ionic strength, we confirm that this equivalence is an inherent property of the Ce3+-DGA system. The Lewis acid-base theory cannot explain why DGA binds to Ce3+ similar to 1000 times more strongly than the other carboxylates. This anomalously strong binding may be due to a chelate effect caused by the DGA’s central oxygen atom, which forms a five-membered ring with the conjugate Lewis bases of DGA; double chelate rings can also form, while bis-deprotonated DGA binds to Ce3+, facilitated by the central oxygen. Therefore, DGA enables efficient quenching through the chelate effect when it binds to Ce3+.

Larval habitats and species diversity of mosquitoes (Diptera: Culicidae) in West Azerbaijan Province, Northwestern Iran

Background The characteristics of a larval habitat is an important factor which affects the breeding pattern and population growth of mosquitoes Information about the larval habitat characteristics and pupal productivity can be utilized for the surveillance of the level of population growth, species diversity, and preferred breeding sites of mosquitoes, which are important aspects of integrated vector control. In the present study, mosquito larvae were collected from 22 natural habitats in five counties of the West Azerbaijan Province in the Northwest of Iran during May-November 2018. Physicochemical characteristics of the habitats were investigated. These included alkalinity, chloride (Cl) content, water temperature (degrees C), turbidity (NTU), Total Dissolved Solids (TDS) (ppm), Electrical Conductivity (EC) (mu S/cm), and acidity (pH). The index of affinity between the collected species was calculated using Fager & McGowan test. Results A total of 2715 specimens were collected and identified. Seven different species belonging to four genera were identified in our study sites. The species included, Culex pipiens Linnaeus 1758, Culex theileri Theobald 1903, Culex mimeticus Noe 1899, Culex modestus Ficalbi 1947, Culiseta longiareolata Macquart 1838, Anopheles maculipennis Meigen 1818complex, and Aedes caspius Pallas 1771. There was a significant difference in chloride content and water temperature preferences among the different species (P < 0.05). Also, there was no significant difference in pH, Alkalinity, Turbidity, TDS, and EC preferences among the different species (P > 0.05). The affinity between the pair of species Cx. mimeticus/Cs. longiareolata was 0.526. There was no affinity between other pairs of species or the affinity was very weak. Conclusions The physicochemical and biological characteristics of mosquito larval habitats play an important role in zoning of areas suitable for breeding and distribution. Surveillance of these characteristics can provide valuable information for entomological monitoring of mosquito vectors and for designing targeted control programs. Also, further studies should be undertaken in a wider geographical area, taking into account the complex characteristics of the physicochemical and ecological factors of the study area and their interaction with various mosquito species.

Peroxymonosulfate activation by carbon-encapsulated metal nanoparticles: Switching the primary reaction route and increasing chemical stability

This study explores the technical merits of carbon encapsulation via an electrical wire explosion method to enhance the peroxymonosulfate activation performance of metals. Reflecting the nature of core-shell structures, the outer carbon layers hampered the reductive conversion of peroxymonosulfate to sulfate radicals by the inner metal cores, whereas the metal cores increased the overall electrical conductivity as a pivotal factor in non radical activation. Hence, the impact of carbon wrapping hinged on the peroxymonosulfate reduction capability of the metals, i.e., kinetic retardation in organic degradation with reactive Cu, Fe, and Ni-Fe, but acceleration with unreactive Ni. Further, composite fabrication switched the major degradative pathway from radical-induced oxidation to mediated electron transfer, as determined from the effects of methanol and chloride, formaldehyde and bromate formation yields, reactivity toward multiple organics, and electron paramagnetic resonance spectral features. The protective carbon shells enabled pH-insensitive peroxymonosulfate activation, prevented metal ion leaching, and alleviated catalyst deactivation.

Grapefruit Seed Extract as a Natural Food Antimicrobial: a Review

In agreement with the recent trend of consumers’ demand for natural antimicrobial products, the importance of using natural compounds in food is increasing. Among numerous natural compounds, grapefruit seed extract (GSE) is widely known for its extremely effective antimicrobial activity. The direct use of GSE in food is the most common method of application. Other GSE applications exist using it with coating materials and incorporating it into edible films. Previously done studies identified benzalkonium chloride, benzethonium chloride, and other synthetic agents from GSE. Unfortunately, the presence of these antibacterial contents does not exactly coincide with the natural aspects of GSE. Even though GSE is identified as a natural antimicrobial, this observation suggests that the GSE antibacterial activity is derived from these synthetic substances such as benzalkonium chloride. Therefore, further research is needed about these controversial issues. This review analyzed the application of GSE as a natural antimicrobial in the food industry and suggested further research directions.

Structure and functionality of oat protein extracted by choline chloride-dihydric alcohol deep eutectic solvent and its water binary mixtures

This research reports an eco-friendly oat protein extraction method using choline chloride (ChCl)-butanediol deep eutectic solvents (DESs) and DES/water binary mixtures. Eighteen formulas consisting of ChCl with butanediol isomer (1,2-butanediol, 1,4-butanediol, or 2, 3-butanediol) in the absence or presence of water at different molar ratio were examined for the synthesis of DESs and binary mixtures. We found that 6 formulae can be fabricated at a ChCl-butanediol molar ratio of 1:3 independent of water presence, and that they had better oat extraction performance with 90 min extraction at 80 degrees C. Under the optimal conditions, we further assessed the impact of butanediol isomers and water addition on the structure characteristics and functionalities of extracted oat protein. The results suggested that oat protein extracted by ChCl-1,4-butanediol/water binary mixture had highest protein content, solubility, foaming capacity and stability. Our pilot findings provide crucial support to our hypothesis that the isomer of hydrogen bond donor is critically involved in the properties of oat protein the DES and the binary mixtures extracted, which pave the way for the future application of DES in protein extraction.
