Despite the successful detection performance of electronic nose in laboratories, they face challenges for use in the industry due to their accuracy reduction resulted from variable ambient properties especially relative humidity (RH) variation which is studied here. Responses of a single temperature modulated metal oxide gas sensor have been analyzed by SVM and k-NN methods to achieve a detector for low concentration levels of acetone, ethanol, 1-propanol and 1-butanol in air. The classifier models were designed and tested under different train-test conditions which showed that studied gases can be detected by the classifier if only they were measured in the same train and test environmental conditions and deviation of humidity level from train condition, reduces the detection accuracy to less than 60%. The accuracy increases by expanding the training dataset and training the system with responses carried out for gas with various RH contents. It was also shown that by using CaCl2 at the rout of gas flow, the destructive effect of RH variation is reduced and the detection accuracy increases to above 90%, while to achieve this accuracy, it is not necessary to train the system in all humidity conditions. By this method, the number of required test for system training reduces drastically. The method can be generalized to other electronic nose and gas detectors which suffer from humidity variations.

Ozonolysis of unsaturated organic species with water produces a-hydroxyalkylhydroperoxides (alpha-HHs), which are reactive intermediates that lead to the formation of H2O2 and multifunctionalized species in atmospheric condensed phases. Here, we report temperaturedependent rate coefficients (k) for the aqueous-phase decomposition of alpha-terpineol alpha-HHs at 283-318 K and terpinen-4-ol alpha a-HHs at 313-328 K. The temporal profiles of alpha-HH signals, detected as chloride adducts by negative-ion electrospray mass spectrometry, showed single-exponential decay, and the derived first-order k for alpha-HH decomposition increased as temperature increased, e.g., k(288 K) = (4.7 +/- 0.2) X 10(-5), k(298 K) = (1.5 +/- 0.4) X 10(-4), k(308 K) = (3.4 +/- 0.9) X 10(-4), k(318 K) (1.0 +/- 0.2) X 10(-3) s(-1) for alpha-terpineol alpha-HHs at pH 6.1. Arrhenius plot analysis yielded activation energies of 17.9 +/- 0.7 (pH 6.1) and 17.1 +/- 0.2 kcal mol(-1) (pH 6.2) for the decomposition of alpha-terpineol and terpinen-4-ol alpha-HHs, respectively. Activation energies of 18.6 +/- 0.2 and 19.2 +/- 0.5 kcal mol(-1) were also obtained for the decomposition of alpha-terpineol alpha-HHs in acidified water at pH 5.3 and 4.5, respectively. Theoretical kinetic and thermodynamic calculations confirmed that both water-catalyzed and proton-catalyzed mechanisms play important roles in the decomposition of these alpha-HHs. The relatively strong temperature dependence of k suggests that the lifetime of these alpha-HHs in aqueous phases (e.g., aqueous aerosols, fog, cloud droplets, wet films) is controlled not only by the water content and pH but also by the temperature of these media.

Purpose: In the present study, we attempted to explore the role of chloride channel 3 (CLC-3) in colorectal cancer (CRC) and its related mechanism. Methods: First, the expression level of CLC-3 in CRC tumor tissues and cell lines were measured by RTqPCR, immunohistochemistry or western blot analysis. CLC-3 expression knockdown in CRC cells was achieved by siRNA transfection. The effect of CLC-3 silence on cell viability, cell cycle, invasion and migration of CRC was estimated by CCK8, flow cytometry based cell cycle assay, and transwell assay, respectively. In order to investigate whether Wnt/beta-catenin signaling was perturbed by CLC-3 knock down, CLC-3 knockdown cells were treated with pathway activator LiCl, followed by the measurement of the expressions of pathway related genes, cell viability, cell cycle, metastasis ability. Results: The expression of CLC-3 was gradually increased from normal adjacent tissues to CRC tumor tissues, and the increase in tumor tissues was related to TNM stages. CLC-3 was overexpressed in four CRC cell lines (HCT116, SW480, LoVo and SW620), compared with NCM460 cells. CLC-3 knockdown significantly reduced cell proliferation, invasion and migration ability, reflected by declined cell viability, arrested G0/G1 cell cycle, decreased invasion and migration ability. In contrast, the declined cell proliferation, invasion and migration of LoVo and SW620 cells induced by CLC-3 knockdown were reversed by the addition of Wnt/beta-catenin activator LiCl. Conclusion: CLC-3 contributed to the CRC development and metastasis through Wnt/beta-catenin signaling pathway. CLC-3 could be proposed as the candidate target for CRC treatment.

The molecular calcium hydride, [(BDI)CaF](2) (BDI = HC{(Me)CN-2,6-i-Pr2C6H3}(2)), effects the slow hydrodehalogenation of C6H5X (X = I, Br) to provide benzene and the respective dimeric calcium halides, [(BDI)CaX](2). Although a similar reaction with fluorobenzene was non-discriminating, the analogous hydrogenation of chlorobenzene was observed, albeit this process yields the calcium hydride-chloride as the alkaline earth-containing product. Assessment of the bromide- and chloride-based processes by density functional theory (DFT) calculations, imply that the reactions take place with the retention of the dimeric calcium structures throughout. Both systems invoke an S N Ar-type displacement of the halide, via barriers (in the range 32-34 kcal mol(-1) for C6H5Br and 31.1-32.9 kcal mol(-1) for C6H5Cl), which vary only marginally during the transformation of the initial hydride and halide-hydride intermediates. The isolation of the calcium hydride-chloride is ascribed, therefore, to its more rapid crystallisation and depletion from solution. Also reported is the reactivity of [(BDI)CaH](2) with alpha,alpha,alpha-trifluorotoluene and anisole, which yield the corresponding dicalcium hydride-fluoride and phenoxide derivatives, respectively, rather than the products of directed ortho metalation.

In the present work, we investigated the minimal inhibitory concentration (MIC) against fungal strains (Fonsecaea pedrosoi, Microsporum canis, Candida albicans, Cryptococcus neoformans), and cytotoxicity to normal cell lines for modified red angico gum (AG) with eterifying agent N-chloride (3-chloro-2-hydroxypropyl) trimethylammonium (CHPTAC). Quaternized ammonium groups were linked to AG backbone using N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride. The chemical features of the quaternized gum derivatives (QAG) were analyzed by: FTIR, elemental analysis, Zeta potential and gel permeation chromatography. The angico quaternizated gum presented a degree of substitution (DS) of 0.22 and Zeta potential of +36.43. For the antifungal test, it was observed that unmodified gum did not inhibit fungal growth. While, QAG inhibited the growth of most fungi used in this study. By AFM technique QAG interacted with the fungal surface, altering wall roughness significantly. The probable affinity of fragments of the QAG structure for the fungal enzyme 5I33 (Adenylosuccinate synthetase) has been shown by molecular docking. Low cytotoxicity was observed for polymers (unmodified gum and QAG). The results demonstrate that the quaternized polymer of AG presented in this study is a quite promising biomaterial for biotechnological applications. Published by Elsevier B.V.

This paper investigates the assessment of corrosion effects on the performance of the composite bridge caused by chloride ions during the service life depending on Cellular Automata (CA) and Finite Element Method (FEM). It also provided a detailed guide to evaluate the performance of existing bridges. Firstly, the diffusion of chloride ions process in the bridge deck is simulated based on the 2D-CA and the initial corrosion time of reinforcement bars and cracking time in the bridge deck is predicted under the effect of multiple factors such as time, water-cement ratio (w/c), temperature and stress state. Secondly, chloride ions’ corrosion effect on the steel girder of the bridge is simulated using 3D-CA. The CA algorithms are developed in MATLAB to achieve this purpose. Thirdly, the degraded steel-concrete composite bridge according to CA-based simulations is analysed based on (FEM). Finally, a numerical simulation of the composite bridge performance for different service process under chloride ion corrosion is achieved under different service periods.

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.

Herein, we report the design of novel ultraviolet luminescent CsPbCl3 nanocrystals (NCs) with the emission peak at 381 nm through doping of cadmium ions. Subsequently, a surface passivation strategy with CdCl2 is adopted to improve their photoluminescence quantum yield (PLQY) with the maximum value of 60.5 %, which is 67 times higher than that of the pristine counterparts. The PLQY of the surface passivated NCs remains over 50 % after one week while the pristine NCs show negligible emission. By virtue of density functional theory calculations, we reveal that the higher PLQY and better stability after surface passivation may result from the significant elimination of surface chloride vacancy (V-Cl) defects. These findings provide fundamental insights into the optical manipulation of metal ion-doped CsPbCl3 NCs.

Deep compositional understanding of TBA: AlCl3 ionic liquid for its applications

Chloroaluminate ionic liquids (ILs) have been immensely used as homogeneous catalyst in Friedel-Crafts reaction. We have recently synthesized chloroaluminate ILs by reacting aluminium chloride with a hydrophobic neutral ligand i.e. tributylamine (TBA:AlCl3). The current study elaborates on the investigations of the composition of the ionic liquids at various stages of their formation. The ionic liquids were synthesized using various mole ratios of tributyl amine and aluminium chloride in range of 1:1 to 1:2.3, in presence of an aromatic solvent in a one pot reaction. Various characterization techniques like Mass spectrometry, Al-27 Nuclear Magnetic Resonance, P-31 Nuclear Magnetic Resonance and Fourier Transform Infrared spectroscopy were used to elucidate the formation of various moieties of the TBA:AlCl3 Ionic Liquid. This study also elaborates on the investigations of the cationic and anionic moieties and their structure-property relationship for various applications. Various Friedel-Crafts reaction of industrial importance were performed using the ionic liquid having (Al2Cl7)(-) moiety to assess its performance and compared with conventional processes. The synthesized products were characterised by sophisticated analytical techniques like H-1 NMR, C-13 NMR, FTIR, GC-MS, GC-FID, to name a few. This class of ionic liquids also have importance in various electrochemical applications like aluminium deposition and aluminium batteries. (C) 2020 Elsevier B.V. All rights reserved.

Locomotor deficits induced by lumbar muscle inflammation involve spinal microglia and are independent of KCC2 expression in a mouse model of complete spinal transection

Spinal cord injury (SCI) is associated with damage to musculoskeletal tissues of the spine. Recent findings show that pain and inflammatory processes caused by musculoskeletal injury mediate plastic changes in the spinal cord. These changes could impede the adaptive plastic changes responsible for functional recovery. The underlying mechanism remains unclear, but may involve the microglia-BDNF-KCC2 pathway, which is implicated in sensitization of dorsal horn neurons in neuropathic pain and in the regulation of spinal excitability by step-training. In the present study, we examined the effects of step-training and lumbar muscle inflammation induced by complete Freund’s adjuvant (CFA) on treadmill locomotion in a mouse model of complete spinal transection. The impact on locomotor recovery of each of these interventions alone or in combination were examined in addition to changes in microglia and KCC2 expression in the dorsal and ventral horns of the sublesional spinal cord. Results show that angular motion at the hip, knee and ankle joint during locomotion were decreased by CFA injection and improved by step-training. Moreover, CFA injection enhanced the expression of the microglial marker Ibal in both ventral and dorsal horns, with or without step-training. However, this change was not associated with a modulation of KCC2 expression, suggesting that locomotor deficits induced by inflammation are independent of KCC2 expression in the sublesional spinal cord. These results indicate that musculoskeletal injury hinders locomotor recovery after SCI and that microglia is involved in this effect.
