Selective Determination of Copper(II) Based on Cu(II)-Metal-Organic Framework in different Water Samples

Four new modified electrodes are carbon pasted (o-NPOE; electrode I and DOS; electrode II); and screen-printed electrodes (o-NPOE; electrode III and DOS; electrode IV) based on Cu(II)-metal-organic framework ionophore were constructed for determination of copper ion (Cu(II)) over wide concentration ranges. The prepared electrodes exhibit Nernstian slope of 28.81 +/- 0.31, 29.43 +/- 0.74, 29.61 +/- 0.20 and 30.04 +/- 0.22 mV decade(-1) towards Cu(II) ion over a wide concentration range of 10(-6) – 10(-2) and 4.9 x 10(-7) – 1.0 x 10(-2) mol L-1 with a detection limit of 1.0 x 10(-6) and 4.9 x 10(-7) mol L-1 at pH range from 3.0 – 8.0, 3.0 – 8.5, 3.0 – 8.0 and 2.5 – 8.5 for electrodes I, II, III and IV, respectively. Updated electrodes exhibited a stable and repeatable potential throughout 86, 103, 195 and 205 days for electrodes I, II, III and IV, respectively. The modified electrodes showed strong selectivity for Cu(II) ion against a large variety of cations. The suggested electrodes were effectively used for the identification of Cu(II) ion in various samples of water and the produced data were well compared to the results obtained using inductively coupled plasma atomic emission spectrometry (ICP-AAS).

Effect of Adding Potassium Chloride on Tetra-n-butyl Ammonium Chloride Semiclathrate Thermal Stability at Atmospheric Pressure

Tetra-n-butyl ammonium chloride (TBAC) is known to form semiclathrate complexes with water. In this work, the melting points and latent heats of fusion of these semiclathrate structures were determined using Differential Scanning Calorimetry (DSC). A phase diagram was created for binary TBAC-H2O from 0 to 7.775 molal TBAC at atmospheric pressure. Below 2 molal TBAC, the semiclathrate is in equilibrium with free, bulk water. At approximately 2 molal TBAC a congruent melting point at 286.96 K is observed in this phase diagram. Beyond this composition, there is no free, bulk water present, and there are multiple forms of the TBAC-H2O semiclathrate complexes with varying amounts of water. Ternary TBAC-KCl-H2O systems were created by adding KCl to 1, 1.5, 2, 3, and 4 molal TBAC solutions to give ionic strength fractions of TBAC (Y-TBAC) from 0.25 to 1. It was found that the melting points of the TBAC-H2O semiclathrate were unaffected as long as there was a sufficient amount of free, bulk water at concentrations less than 2 molal TBAC. However, at greater concentrations, adding KCl disrupted the normal TBAC-H2O semiclathrate complex, and KCl was incorporated into new, TBAC-KCl-H2O complexes that melted at higher temperatures than previously reported for similar TBAC-NaCl-H2O complexes.

Correlating in vitro performance with physico-chemical characteristics of nanofibrous scaffolds for skin tissue engineering using supervised machine learning algorithms

The engineering of polymeric scaffolds for tissue regeneration has known a phenomenal growth during the past decades as materials scientists seek to understand cell biology and cell-material behaviour. Statistical methods are being applied to physico-chemical properties of polymeric scaffolds for tissue engineering (TE) to guide through the complexity of experimental conditions. We have attempted using experimental in vitro data and physico-chemical data of electrospun polymeric scaffolds, tested for skin TE, to model scaffold performance using machine learning (ML) approach. Fibre diameter, pore diameter, water contact angle and Young’s modulus were used to find a correlation with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay of L929 fibroblasts cells on the scaffolds after 7 days. Six supervised learning algorithms were trained on the data using Seaborn/Scikit-learn Python libraries. After hyperparameter tuning, random forest regression yielded the highest accuracy of 62.74%. The predictive model was also correlated with in vivo data. This is a first preliminary study on ML methods for the prediction of cell-material interactions on nanofibrous scaffolds.

Effect of adding copper oxide nanoparticles on the mass/heat transfer in falling film absorption

Absorber is an essential component that affects the efficiency of absorption refrigeration unit. Falling film absorption is one of the most widespread forms of the heat/mass transfer in absorption system. In this paper, based on the software COMSOL Multiphysics, the finite element method is used to establish the model of falling film absorption. The falling film absorption properties of nanofluids was studied by adding CuO nanoparticles. The results reveal that as the film flow rate increases, the average mass transfer flux rises first and then decreases. The average mass transfer flux increases with the rise of the concentration of solution at the inlet, the decrease of the temperature of solution at the inlet and the reduction of cooling water inlet temperature. After adding copper oxide nanoparticles to lithium bromide solution, the vapor absorption performance of lithium bromide solution can be significantly improved.

A dual promotion strategy of interface modification and ion doping for efficient and stable carbon-based planar CsPbBr3 perovskite solar cells

Carbon-based all-inorganic cesium lead bromide (CsPbBr3) halide perovskite solar cells (PSCs) have attracted tremendous attention owing to their low cost, simplified preparation, and outstanding stability even under harsh conditions. However, the CsPbBr3 perovskite always suffers from an undesirable crystallization and film morphology with incomplete coverage and numerous grain boundaries. Herein, a novel dual promotion strategy combining interface modification with ion doping is proposed to achieve highly efficient and stable carbon-based planar CsPbBr3 PSCs. A thin CsBr modified layer was first inserted between the compact TiO2 (c-TiO2) and PbBr2 layers, wherein the crystallization of PbBr2 can be enhanced and then assist the growth of perovskite grains can be provided, so that CsPbBr3 films can reduce pinhole generation and accelerate carrier extraction, and decrease the hysteresis effect. Then an appropriate cobalt (Co2+) ion is doped into the CsPbBr3 film, which not only increases the grain size with decreasing grain boundary, but also ameliorates the energy level and recombination. Consequently, the champion power conversion efficiency (PCE) of the CsPbBr3 PSCs reaches up to 8.67% with an increment of about 30%. Moreover, the best-performing PSC without encapsulation also displays excellent humidity and thermal stability, maintaining above 98% of its initial PCE in an air atmosphere after 100 days, and over 95% under heat treatment at 85 degrees C after 600 hours, respectively. This study provides a promising route to boost the performance of all-inorganic perovskite solar cells.

Evaluation of the Combined Use of Saccharomyces Cerevisiae and Aspergillus Oryzae with Phytase Fermentation Products on Growth, Inflammatory, and Intestinal Morphology in Broilers

Simple Summary The stress and anti-nutrient effect caused by environmental problems and animal feed is an urgent problem in poultry production. As ancient probiotics, Aspergillus oryzae and Saccharomyces cerevisiae can effectively improve the immunity of animals. Furthermore, the anti-nutrient object, phytate, reduces nutrition absorption. Therefore, S. cerevisiae or A. oryzae with phytase co-fermentation may help solve these problems. Results show that the addition of a fermentation product can effectively reduce the inflammatory response and drop the number of harmful bacteria in the ileum of broilers. Among them, A. oryzae fermentation product has a better effect than S. cerevisiae fermentation product. AbstractSaccharomyces cerevisiae and Aspergillus oryzae are both ancient probiotic species traditionally used as microbes for brewing beer and soy sauce, respectively. This study investigated the effect of adding these two probiotics with phytase fermentation products to the broilers diet. Fermented products possess protease and cellulase, and the activities were 777.1 and 189.5 U/g dry matter (DM) on S. cerevisiae fermented products (SCFP) and 190 and 213.4 U/g DM on A. oryzae fermented products (AOFP), respectively. Liposaccharides stimulated PBMCs to produce nitric oxide to 120 mu mol. Both SCFP and AOFP reduced lipopolysaccharides stimulated peripheral blood mononuclear cells (PBMCs) nitric oxide release to 40 and 60 mu mol, respectively. Nevertheless, in an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, SCFP and AOFP also increased the survival rate of lipopolysaccharides stimulated PBMCs by almost two-fold compared to the negative control. A total of 240 broilers were divided into four groups as Control, SCFP 0.1% (SCFP), SCFP 0.05% + AOFP 0.05% (SAFP), and AOFP 0.1% (AOFP) groups, respectively. Each group had 20 broilers, and three replicate pens. The results showed that the addition of SCFP, SAFP, and AOFP groups did not affect the growth performances, but increased the jejunum value of villus height and villus: crypt ratio on SAFP and AOFP groups compared to the control and SCFP groups. Furthermore, adding SCFP, SAFP, and AOFP significantly reduced the number of Clostridium perfringens in ileum chyme. SCFP, SAFP, and AOFP significantly reduced the amount of interleukin-1 beta, inducible nitric oxide synthases, interferon-gamma, and nuclear factor kappa B mRNA expression in PBMCs, especially in the AOFP group. In summary, all the SCFP, SAFP, and AOFP groups can be suggested as a functional feed additive since they enhanced villus: crypt ratio and decreased inflammation-related mRNA expression, especially for AOFP group in broilers.

Catalytic ozonation of emerging pollutant and reduction of toxic by-products in secondary effluent matrix and effluent organic matter reaction activity

In this study, the performance of LaCoO3 (LCO) catalytic ozonation was evaluated comprehensively, including the degradation efficiency of benzotriazole (BZA) as a typical emerging pollutant, toxic bromate reduction and the disinfection by-products (DBPs) precursors removal ability in effluent organic matter (EfOM), as well as EfOM reactive activity in catalytic ozonation. Additionally, the reduction of toxic halogenated by-products in (catalytic) ozonation was reported, which was not focused on previous researches before. Results showed that LCO catalytic ozonation improved the removal efficiency of BZA, UV254 and SUVA via enhanced HO. formation. Interestingly, LCO catalytic ozonation showed the ability on the reduction of aldehydes and toxic halogenated organic by-products. Moreover, the formed [trichloromethane (TCM)], [bromochloroacetonitrile (BCAN)] and [dichloroacetamide (DCAcAm)] decreased significantly in catalytic ozonation. Catalytic ozonation was also able to remove DBPs precursors to decline the formation of DBP5, such as TCM, bromodichloromethane (BDCM), trichloroacetonitrile (TCAN) and trichloronitromethane (TCNM). This process was involved in the transformation of EfOM in catalytic ozonation, which was confirmed by multi-spectrum methods, two-dimensional correlation spectroscopy (2D-COS) and hetero-spectral 2D-COS. In summary, LCO was shown to be an effective catalyst to improve the performance of the sole ozonation on the removal of emerging contaminants and DBP5 precursors, as well as toxic by-products reduction. Additionally, the strategy of toxic by-products reduction in catalytic ozonation was proposed. Results indicated this technology was an important contribution on removal of refractory organics and formation of toxic by-products in water supply and wastewater treatment industry.
