Structure, optical, and radiation shielding properties of PVA-BaTiO3 nanocomposite films: An experimental investigation

Developing different types of radiation shielding with certain specifications according to the type of radiation and method of application is essential. In this work, the radiation shielding, optical and structural features of PVA films containing BaTiO3 nanoparticles are investigated. The radiation shielding properties were measured experimentally with real gamma sources (Ba-133, Eu-152, and Cs-137). The efficiency calibration and spectrum analysis were performed with the Spectra Line Ultimate Gamma Lab packet program. Moreover, the results were compared with the FLUKA Monte Carlo code. Before radiation attenuation measurements, the prepared films were characterized via X-ray diffraction (XRD). The structure of the BaTiO3 nanoparticles in the polymer matrix was studied with a scanning electron microscope (SEM, Merlin, Carl-Zeiss, LE0982). In addition, the optical properties of the polymer films were studied and presented. As the BaTiO3 content increases in the polymer matrix, transmission decreases and reflectance increases. Equally, as the BaTiO3 content increases, the value of a increases. For the shielding properties, the mass attenuation coefficient (mu(m)) increases as the BaTiO3 content increases from 0.65 to 3.57 wt%. There is a strong agreement between experimental results and the values obtained from the FLUKA Monte Carlo code.

A Randomized Trial of Albumin Infusions in Hospitalized Patients with Cirrhosis

BACKGROUND Infection and increased systemic inflammation cause organ dysfunction and death in patients with decompensated cirrhosis. Preclinical studies provide support for an antiinflammatory role of albumin, but confirmatory large-scale clinical trials are lacking. Whether targeting a serum albumin level of 30 g per liter or greater in these patients with repeated daily infusions of 20% human albumin solution, as compared with standard care, would reduce the incidences of infection, kidney dysfunction, and death is unknown. METHODS We conducted a randomized, multicenter, open-label, parallel-group trial involving hospitalized patients with decompensated cirrhosis who had a serum albumin level of less than 30 g per liter at enrollment. Patients were randomly assigned to receive either targeted 20% human albumin solution for up to 14 days or until discharge, whichever came first, or standard care. Treatment commenced within 3 days after admission. The composite primary end point was new infection, kidney dysfunction, or death between days 3 and 15 after the initiation of treatment. RESULTS A total of 777 patients underwent randomization, and alcohol was reported to be a cause of cirrhosis in most of these patients. A median total infusion of albumin of 200 g (interquartile range, 140 to 280) per patient was administered to the targeted albumin group (increasing the albumin level to =30 g per liter), as compared with a median of 20 g (interquartile range, 0 to 120) per patient administered to the standard-care group (adjusted mean difference, 143 g; 95% confidence interval [CI], 127 to 158.2). The percentage of patients with a primary end-point event did not differ significantly between the targeted albumin group (113 of 380 patients [29.7%]) and the standard-care group (120 of 397 patients [30.2%]) (adjusted odds ratio, 0.98; 95% CI, 0.71 to 1.33; P = 0.87). A time-to-event analysis in which data were censored at the time of discharge or at day 15 also showed no significant between-group difference (hazard ratio, 1.04; 95% CI, 0.81 to 1.35). More severe or life-threatening serious adverse events occurred in the albumin group than in the standard-care group. CONCLUSIONS In patients hospitalized with decompensated cirrhosis, albumin infusions to increase the albumin level to a target of 30 g per liter or more was not more beneficial than the current standard care in the United Kingdom.

Biotransformation of spent coffee grounds by fermentation with monocultures of Saccharomyces cerevisiae and Lachancea thermotolerans aided by yeast extracts

Spent coffee grounds (SCG) is a low-value solid food waste generated from the rising consumption of coffee. There is a need to transform the huge amount of SCG to value-added products such as alcoholic beverages. In this study, monocultures of Saccharomyces cerevisiae Merit and Lachancea thermotolerans Concerto were used to ferment SCG hydrolysates supplemented with yeast extracts. The addition of yeast extracts slightly enhanced the growth of both S. cerevisiae Merit and L. thermotolerans Concerto. In addition, the yeast extracts also increased the production of organic acids (e.g. succinic acid and acetic acid) and volatiles such as 2-phenylethyl alcohol and ethyl esters (e.g. ethyl octanoate and ethyl 2,4-hexadienoate). Furthermore, the supplementation of yeast extracts showed a more significant effect on the performance (e.g. yeast growth) of S. cerevisiae Merit than that on L. thermotolerans Concerto. Our results indicated that the addition of yeast extracts may provide a new strategy to enhance the transformation of SCG into a potential alcoholic beverage with flavor compound complexity.

A high ZIF-8 loading PVA mixed matrix membrane on alumina hollow fiber with enhanced ethanol dehydration

In this work, a zeolitic imidazolate framework-8 (ZIF-8)/polyvinyl alcohol (PVA) mixed matrix membrane (MMM) was coated onto a-aluminum oxide (alpha-Al2O3 ) hollow fibers for ethanol dehydration by utilizing the pervaporation technique. ZIF-8/PVA solution was prepared via a drying-free, water-based method to obtain a uniform distribution MMM. Before coating the MMM onto the hollow fiber, a pristine PVA solution was first dipcoated onto hollow fiber as a gutter layer to prevent phase separation. Different weight ratios of ZIF-8-loaded MMMs were prepared. The results showed that at high ZIF-8 loading (39 wt %), a high permeate flux (685 g/ m(2) h) and high separation factor (4821) can be observed. Furthermore, compared with free-standing ZIF-8/PVA MMMs, hollow fiber supported ZIF-8/PVA MMMs exhibit a thinner coating thickness but higher pervaporation separation index (approximately 1.5-2 times). The main contribution of this study is not only fabricated the high loading ZIF-8/PVA composite membrane with enhanced performance, but also coated onto the hollow fiber membrane which opens a gate for scale-up production.

Photochemistry of biochar during ageing process: Reactive oxygen species generation and benzoic acid degradation

In this study, the photogeneration of center dot OH and O-1(2) and the degradation mechanism of organic pollutants in biochar suspension under the simulated solar light irradiations were investigated. Biochar derived from rice husk with 550 degrees C of charring temperature (R550) was selected to degrade benzoic acid. It was found that 10 g/L of R550 could degrade 78.7% of benzoic acid within 360 min at pH 3, and the degradation efficiency was promoted to 95.2% as ultraviolet (UV) presented. By checking the production of p-hydroxybenzoic acid, UV accelerated the production of center dot OH, which was confirmed by the enhanced degradation efficiency of 59.2% caused by the evaluated center dot OH as UV appeared. The furfuryl alcohol loss in the R550 suspension under light irradiations testified to the production of O-1(2), which contributed to 9.3% of benzoic acid degradation. Oxidization treatment using gradient concentrations of H2O2 was employed to enhance the ageing process of biochar. As the ageing processed, the biochar possessed a declined performance towards center dot OH production from O-2 activation and the radical degradation of organic pollutants. As a contrast, the evaluated content of O-1(2) and enhanced non-radical degradation of organic pollutants was reached as UV presented. The further study indicated that phenolic hydroxyl groups on biochar facilitated the production of center dot OH via the electron transfer, and quinone like structures (C=O) on biochar boosted the generation of O-1(2) via the energy transfer. Moreover, upon eliminating the BA degradation, persistent free radicals were formed on biochar, which was enhanced owing to the presence of UV. (C) 2020 Published by Elsevier B.V.

Synthesis and electrochemical properties of V(2)O(5)(center dot)nH(2)O compound with reduced graphene oxide/polyvinyl alcohol film as the free-standing cathode for coin-typed aqueous Zn-ion batteries

Recently aqueous zinc-ion batteries (AZIBs) have been widely studied on the aspects of electrode materials and electrolytes, but it is still far from practical application. The limitation of AZIBs is that it is difficult to have both high specific capacity and good cycle stability. Herein, a free-standing cathode V(2)O(5)(center dot)nH(2)O/reduced graphene oxide-polyvinyl alcohol (denoted as V(2)O(5)(center dot)nH(2)O/rGO-PVA) film was synthesized by one-step hydrothermal method and vacuum filtration. As the cathode for the coin-typed AZIBs, the V(2)O(5)(center dot)nH(2)O/rGO-PVA film cathode delivers the ultrahigh capacity of 553 mA h g(-1) at the current density of 0.1 A g(-1). And the capacity is 194 mA h g(-1) at 0.5 A g(-1), after 300 cycles, it still remains 152 mA h g(-1). At the power density of 183 W.kg(-1), the high energy density is calculated as 354 Wh.kg(-1) based on the mass of the cathode. The energy storage mechanism was studied by some ex-situ characterizations as well. This work not only proposes a strategy for the synthesis of V(2)O(5)(center dot)nH(2)O/rGO-PVA film, but also demonstrates that the as-obtained free-standing cathode is beneficial to the assembly of coin-typed AZIBs and exhibits excellent electrochemical performance.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5675-51-4, you can contact me at any time and look forward to more communication. Recommanded Product: 5675-51-4.

Co-Cd nanoferrite for high frequency application with phenomenal rise in DC resistivity

The communication concentrates on the possibility of developing a composition suitable for high-frequency operation as a magnetic core through an extensive understanding of the cation distribution of cobalt ferrite containing cadmium. The samples having a composition, Co1-xCdxFe2O4, were processed by the sol-gel method using polyvinyl alcohol (PVA) as a chelating agent and characterized by standard techniques. Substantial growth in specific saturation magnetization from 82.2 emu/g to 99 emu/g and DC resistivity from 1.54 x 10(6) Omega-cm to 1.34 x 10(11) Omega-cm, requisite characteristics for high-frequency application were provided with increasing concentration of cadmium. The average crystallite size ranging from 5.7 nm to 17 nm has been estimated by X-ray diffraction patterns using Williamson-Hall analysis. The proposed cation distribution based on saturation magnetization data established the amount of cadmium occupying the tetrahedral sites of spinel lattice, which was well supported by the variation of DC resistivity with cadmium. The unparalleled matching between the experimentally observed lattice constant and that provided by the proposed cation distribution as well as Rietveld refinement confirms the amounts of cadmium entering tetrahedral and octahedral sites of the spinel lattice. All the samples of cadmium substituted cobalt ferrite assure their suitability for high frequency application with the pertinent properties.

ultrasonography of kidney and spleen in clinically healthy llamas and alpacas

Background: The ultrasonographic examination technique is a well-established, non-invasive diagnostic tool for diverse conditions in humans and different animal species. The purpose of our study was to describe ultrasonographic localisation, sonographic appearance and dimensions of the kidneys and spleen of clinically healthy llamas and alpacas. Differences between llamas and alpacas and the influence of sex and ages were investigated. Results of this study may aid veterinarians performing ultrasonography in diseased animals and the technique can be used for routine protocol screening. Results: Ultrasonography was performed in 135 clinically healthy, non-sedated llamas and alpacas. Screening was performed with a 6.6 MHz curve linear transducer with only alcohol as contact medium between the probe and unclipped skin. The kidneys could be imaged from the paralumbar region. The right kidney only was visualized when scanning from the right and the left kidney only from the left. While the left kidney appeared in sagittal view as an oval shape in most llamas and alpacas, in one third of animals the left kidney had a triangular shape. The L-shaped base of the spleen, with its homogeneous, echoic pattern, could be seen craniolateral to the left kidney. Anechoic areas displaying vessels inside the spleen and a thin echoic capsule surrounding the splenic tissue could be differentiated. While sonographic appearances of the examined organs showed no differences between llamas and alpacas, selected dimensions of both of kidney and spleen showed significant differences between species. In terms of age and sex, significant differences in respect of kidney size could be found only in alpacas. Sex seemed to have no influence on kidney and spleen sizes in llamas. Conclusions: The present study provides species-specific information on ultrasonographic appearance and reference values for kidney and spleen dimensions of clinically healthy llamas and alpacas. Results show differences in organ sizes between llamas and alpacas and in alpacas of different sex and age. The results of this study can be used as references for veterinarians performing ultrasound examinations in diseased animals.

Solubility determination, model evaluation, Hansen solubility parameter and thermodynamic properties of benflumetol in pure alcohol and ester solvents

The equilibrium solubility and thermodynamic properties of benflumetol in methanol, ethanol, npropanol, n-butanol, n-pentanol, n-hexanol, n-heptanol, n-octanol, methyl acetate, ethyl acetate, n-propyl acetate, n-butyl acetate and n-pentyl acetate were reported. Solubility determinations were performed through the laser monitoring method at T = (278.15-323.15) K and p = 101.3 kPa. It is found that the mole fraction solubility of benflumetol increases apparently with the augmented experimental temperature. In addition, the solubility of benflumetol in all ester solvents is greater than that in alcohol solvents. The maximum mole fraction solubility of benflumetol is obtained in n-pentyl acetate (4.061 x 10(-2), T = 323.15 K), and the minimum mole fraction solubility of benflumetol is obtained in methanol (1.341 x 10(-5), T = 278.15 K). The Hansen solubility parameter for benflumetol as well as selected solvents was summarized to analyse the probabilities of miscibility between solute and solvents. The analysis consequence shows that the miscibility of benflumetol with selected solvents is caused by a combination of factors. All recorded solubility of benflumetol were regressed by 9.11 model, modified Apleblat model, two-Suffix Margules model, NRTL model and UNIQUAC model. By comparison, it can be found that the average ARD and 10 4 RMSD of the modified Apelblat model and NRTL model are smaller than the other three models, indicating that these two moedls are more suitable for correlating the solubility data. In addition, the apparent thermodynamic properties of benflumetol in all neat solvents were calculated and investigated by the Van’t Hoff equation. The results illustrated that the dissolution process of benflumetol is an entropy-driven endothermic process. (C) 2020 Elsevier Ltd.
