Direct conversion of ester bond-rich waste plastics into hard carbon for high-performance sodium storage

Disordered hard carbon (HC) has shown potential as the most promising anode materials for sodium-ion batteries (SIBS). Pyrolyzing waste plastics is a sustainable alternative to obtain HC. However, most plastics will completely decompose without carbon residue or transform into highly graphitic carbon during the carbonation process because of lacking oxygen functional groups. Hence, ester bond-rich waste engineering plastics, polycarbonate (PC), and polyethylene terephthalate (PET) were selected and directly converted into HC by a simple pyrolysis method. The PC and PET-derived carbon anodes (PC-HC and PET-HC) exhibit high reversible capacities of 327 and 342 mAh.g(-1) at 20 mA.g(-1) with remarkable initial coulombic efficiency (ICE) of 84.7% and 86.1%, respectively. Particularly, the carbon samples have no severe capacities decay after 140 cycles at 100 mA.g(-1). This work provides a cost-effective, easily large-scale, and eco-friendly route to fabricate HC anodes for grid-scale energy storage. (C) 2020 Elsevier Ltd. All rights reserved.

Microphase separation/crosslinking competition-based ternary microstructure evolution of poly(ether-b-amide)

The temperature dependence of the rheological properties of poly(ether-b-amide) (PEBA) segmented copolymer under oscillatory shear flow has been investigated. The magnitude of the dynamic storage modulus is affected by the physical microphase separation and irreversible crosslinking network, with the latter spontaneously forming between the polyamide segments and becoming the dominant factor in determining the microstructural evolution at temperatures well above the melting point of PEBA. From the rheological results, the initial temperature of the rheological properties dominated by the microphase separation and crosslinking (T-cross) structures were determined, respectively. Based on the two obtained temperatures, the microstructure evolution upon the heating can be separated into the ternary microstructure domains: homogenous (temperature below ), microphase separation dominating (between and T-cross), and crosslinking dominating domains (above T-cross). When the PEBA is heated to above T-cross, the content of crosslinking network increases with time and temperature, leading to an irreversible and non-negligible influence on the rheological, crystallization, and mechanical properties. A more pronounced strain-hardening phenomenon during the uniaxial stretching is observed for the sample with a higher content of crosslinking network.

Rapid and sensitive UHPLC-DAD method for simultaneous determination of sofosbuvir and ledipasvir in human serum

Today, the direct-acting antiviral agents (DAAs) such as sofosbuvir (SOF) and ledipasvir (LED) are widely used to treat the hepatitis virus infection. The aim of this study was to develop a rapid, simple and valid method for simultaneous determination of SOF and LED in human plasma for bioavailability and pharmacokinetic studies. Chromatographic analysis was performed on the C-18 column (Blue Orchid, 1.8 mu m, 50 x 2 mm) using 0.1 % formic acid in water (pH 2.6) and acetonitrile (60:40; v/v) as mobile phase at a flow rate of 0.5 mL/min. The UV detector was set at 328 nm and 260 nm for analysis of SOF and LED, respectively. To 400 mu L of plasma, 100 mu L of clonazepam as the internal standard (I.S, 7 mu g/mL) was added and the mixture subjected to liquid-liquid extraction using 1000 mu L diethyl ether. The calibration curves were linear with coefficients of variation less than 8% for all analyses. The limit of quantification (LOQ) was 20 and 5 ng/mL for SOF and LED, respectively. The results of inter-day and intra-day precision showed good reproducibility and the total analysis time was 1.2 min. This method successfully applied for determination SOF and LED in four healthy volunteers. (C) 2020 Published by Elsevier B.V.

First stable (Z)-configuration of cyanostilbene derivative: An effective turn-on fluorescent sensor for lysine in aqueous media

Due to the rapid E/Z isomerization of cyanostilbene under light or heating, the stable (Z)-configuration of cyanostilbene was hard to be obtained although many (E)-cyanostilbene derivatives had been reported as excellent fluorescence sensor. In this work, the first stable (Z)-configuration of cyanostilbene derivative (Z)-CS bridged by crown-ether chain was designed and synthesized under the irradiation of UV365 and heating. The stable (Z)-configuration was attributed to the short bridging crown-ether chain which restricted the E/Z isomerization of cyanostilbene. (Z)-CS exhibited the weak AIE effect in H2O/DMSO system, but showed the strong turn-on fluorescence enhancement after adding lysine. The detection limit of (Z)-CS for lysine attained 1.34 x 10(-7) M. The selective sensing behavior for lysine was stable in pH = 6-9 and was little interfered by other species. The 1:1 sensing mechanism was proposed by the investigation of Job’s plot, H-1 NMR and MS binding spectra. The sensing ability of (Z)-CS was successfully applied for analyzing lysine in urine samples of human body. (Z)-CS also displayed the good bioimaging performance with enhanced blue-purple fluorescence after detecting lysine. The work not only presented an effective fluorescence sensor for lysine in aqueous media, but also confirmed firstly the excellent application prospect of stable (Z)-configuration of cyanostilbene as fluorescence probe in complicated and living environment.

Is Palm Kernel Cake a Suitable Alternative Feed Ingredient for Poultry?

Simple Summary Supply of raw materials such as corn and soybean meal as livestock and poultry feeds may be limited and is a significant concern during the Covid-19 pandemic especially for the countries that depend on importation of raw materials. Consequently, the palm kernel cake has been proposed as an alternative raw material for animal feeds to reduce importation dependency. The chemical composition of palm kernel cake varies depending on the method of oil extraction. The crude fiber content of palm kernel cake is acceptable to most ruminants but is considered high for poultry. Biodegradation of palm kernel cake through solid-state fermentation can improve its nutritional quality, improving broiler health status and growth performance. Palm kernel cake (PKC), a by-product of oil extracted from palm nuts through expeller press or solvent extraction procedures is one of the highest quantities of locally available and potentially inexpensive agricultural product. PKC provides approximately 14-18% of crude protein (CP), 12-20% crude fiber (CF), 3-9% ether extract (EE), and different amounts of various minerals that feasible to be used as a partial substitute of soybean meal (SBM) and corn in poultry nutrition. Poultry’s digestibility is reported to be compromised due to the indigestion of the high fiber content, making PKC potentially low for poultry feeding. Nevertheless, solid-state fermentation (SSF) can be applied to improve the nutritional quality of PKC by improving the CP and reducing CF content. PKC also contains beta-mannan polysaccharide, which works as a prebiotic. However, there is a wide variation for the inclusion level of PKC in the broiler diet. These variations may be due to the quality of PKC, its sources, processing methods and value-added treatment. It has been documented that 10-15% of treated PKC could be included in the broiler’s diets. The inclusion levels will not contribute to a negative impact on the growth performances and carcass yield. Furthermore, it will not compromise intestinal microflora, morphology, nutrient digestibility, and immune system. PKC with a proper SSF process (FPKC) can be offered up to 10-15% in the diets without affecting broilers’ production performance.

Tannic acid and Poly(N-acryloyl morpholine) layer-by-layer built hemodialysis membrane surface for intervening oxidative stress integrated with high biocompatibility and dialysis performance

Oxidative stress is a compelling risk factor during hemodialysis in patients with renal failure to elevated mortality risk. Intervening the effect of oxidative stress in the pathogenesis of dialysis-associated complications requires developing a more direct hemodialysis membrane route to prevent and relieve oxidative stress in the dialysis process. In this work, combining the anti-oxidative property of tannic acid (TA) and high biocompatibility of poly (N-acryloyl morpholine) (PACMO), the TA-PACMO functionalized poly (ether sulfone) (PES) hemodialysis membranes have been fabricated using the hydrogen-bonded layer-by-layer (HB-LbL) assembly technology. The functionalized membranes directly quenched excess reactive oxygen species, improved the serum total antioxidant capacity, and suppressed lipid peroxidation and protein glycosylation. More interestingly, the TA-PACMO functionalized hemodialysis membranes effectively protected cardiomyocytes (H9C2), and vascular endothelial cells (HUVEC) from oxidative damage the improvement of antioxidant enzymes activities such as superoxide dismutase and catalase. The introduction of PACMO indicated in considerable improvement of blood compatibility and reduction of complement activation compared to a single TA modified hemodialysis membrane. The typical toxins, including urea and lysozyme, were efficiently removed from the dialysis simulant experiment, confirming the feasibility of the TA-PACMO HB-LbL functionalized strategy. The results revealed that, with the TA-PACMO content increasing, the functionalized membranes with superior comprehensive performances had stronger anti-oxidative stress, better biocompatibility, and more efficient dialysis performance. The present work provided a promising candidate in the development and application of hemodialysis membrane against oxidative stress, which alleviated patients’ complications to address the long-term hemodialysis.

Molecular identification of Entamoeba histolytica, E. dispar y E. moshkovskii in children with diarrhea from Maracaibo, Venezuela

Introduction: Entamoeba histolytica is the amebiasis-producing parasite, however; Entamoeba dispar, Entamoeba moshkovskii and Entamoeba bangladeshi are nonpathogenic amoebae, morphologically identical to this one, so molecular techniques are needed for their differentiation. Objective: To identify the frequency of Entamoeba species by Polymerase Chain Reaction (PCR), in fecal samples from children under 5 years of age with diarrhea, from Maracaibo, Venezuela. Materials and methods: A fecal sample was collected per individual from 75 children with diarrhea (case group) and 25 children without diarrhea (control group). Stools were evaluated by microscopic examination, formol-ether concentration method and nested-multiplex PCR in a single round, for the identification of E. histolytica, E. dispar and E. moshkovskii. In addition, a survey was conducted in which demographic data, signs, clinical manifestations, and socioeconomic status were defined. Results: 48% of the children (38 from the case group and 10 from the control group) had intestinal parasites. Only 4 children presented cysts of the Entamoeba complex in their samples, (3 from case group and 1 control group). By means of PCR 9 samples (9%) amplified for the studied amoebae. In the case group: 3 (28.13%) for E. histolytica, 4 (30.50%) for E. dispar and 1 (9.37%) for E. moshkovskii; while only 1 (25%) sample amplified for E. dispar in the control group. Conclusion: In general, E. dispar predominated; however, all those infected with E. histolytica were detected within the group of children with diarrhea and the first case of E. moshkovskii was detected in the region.

Numerical modelling of sorption-enhanced gasification: Development of a fuel decomposition model

Sorption-enhanced gasification (SEG) is a promising technology for producing renewable feedstock gas to be used in biofuel synthesis processes, especially in dimethyl ether (DME) synthesis. To adopt the technology on a commercial scale, it is necessary to acquire knowledge about the related operational characteristics. The SEG process is carried out at lower temperatures than those employed in conventional gasifiers. A typical operating range is from 600 degrees C to 800 degrees C. Fuel decomposition experiments have shown distribution of the decomposition products to vary by the process temperature in this operating range, and thus, it is important to adapt this phenomenon for modelling the SEG process. To model the temperature dependence of the decomposition products, a fuel model was developed. Fuel decomposition experiments were conducted to obtain the boundary conditions for the fuel model. The developed fuel model was implemented to an SEG model frame, and the model prediction was compared against data from a 200 kWth dual fluidised bed facility. The model gave satisfactory predictions for producer composition and temperature trends. Furthermore, the main balances of the model were in agreement with typical trends of the SEG process. The conducted simulations improved our understanding of material balances in SEG reactors. Knowledge from physical operations governing the process is of value in further development of the technology.

Mixed lithium fluoride-nitride ionic conducting interphase for dendrite-free lithium metal anode

The lithium (Li) metal battery reveals appealing merits in energy density but suffers from problems of dendrite growth and low coulombic efficiency before its applications. The ether electrolytes entitle Li metal batteries with more smooth Li stripping/deposition but narrow electrochemical stability in contrast to carbonate electrolyte. circumventing this contradictory, a lithium fluoride-nitride mixed ionic conducting interphase was embedded on lithium surface via formulated fluorine-rich carbonate and cyclophosphonitrile, which renders a dendrite-free plating/stripping over 2200 h and extend the electrochuemcial window of ether electrolyte to 4.5 V with the assistance of experiments and calculating simulations, ensuring LiCoO2 to operate efficiently over 200 cycles with nearly no capacity decay.

A novel porous polymeric microsphere for the selective adsorption and isolation of conalbumin

Porous polymeric microspheres, poly(styrene-divinyl benzene, PSDVB)-poly(ethylene glycol monoallyl ether, PEGMAE), termed as PSDVB-PEGMAE, are prepared via double emulsion interfacial polymerization strategy. PSDVB-PEGMAE microspheres exhibit a mean diameter of 2.98 um, and possess heterogeneous porous structure with a pore volume of 0.354 cm(3) g(-1) and a pore size of 34.3 nm. PEGMAE moiety is identified on the external surface of the microspheres, while both PSDVB and PEGMAE moieties are found in the interior pores. The PSDVB-PEGMAE microspheres possess favorable selectivity towards the adsorption of conalbumin (ConA) through hydrogen-bonding and hydrophobic interactions, via surface and inter-pore adsorption. At pH 6, an adsorption capacity of 171.9 mg g(-1) is achieved for ConA. The captured ConA may be readily recovered by stripping with a cetane trimethyl ammonium bromide (CTAB) solution (0.1%, m/v). The microspheres are further used for the isolation of ConA from egg white, deriving high purity ConA as demonstrated by SDS-PAGE assay. (C) 2020 Elsevier B.V. All rights reserved.
