Production of manno-oligosaccharide from Gleditsia microphylla galactomannan using acetic acid and ferrous chloride

A novel and efficient method for manno-oligosaccharides (MOS) production has been proposed by utilizing Gleditsia microphylla galactomannan as the starting material. This co-operative hydrolysis using ferrous chloride (Fe2+) and acetic acid (HAc) effectively improved the MOS yield and meanwhile decreased the amount of monosaccharide and the 5-hydroxymethyl-furfural (HMF). The highest yields under the optimum conditions were 46.7% by HAc hydrolysis (5 M HAc at 130 degrees C for 120 min); 37.3% by Fe2+ hydrolysis (0.1 M Fe2+ at 150 degrees C for 120 min); and 51.4% by co-operative hydrolysis (2 M HAc, 0.05 M Fe2+ at 160 degrees C for 10 min). From the changes in the value of M/G (mannose/galactose) ratios, it was deduced that Fe2+ predominantly cleaves the main chain, and HAc assists in the breakage of the side chain, thus resulting in the high-efficient co-operative hydrolysis for the production of MOS.

Influence of chloride ions concentration on the development of severe localised corrosion and its effects on the electrochemical response of the 2198-T8 alloy

The development of severe localised corrosion (SLC) on the 2198-T8 alloy was investigated in solutions of various NaCl concentrations (0.001, 0.005 and 0.01 mol L-1). Immersion tests, optical profilometry, conventional and local electrochemical analyses were performed to evaluate the corrosion behaviour of the alloy. Immersion tests showed that the alloy is susceptible to SLC in all conditions, although the pits sizes were dependent on the solution concentration. The largest anodic areas, corresponding to SLC sites, were observed for the sample immersed in 0.001 mol L-1 NaCl, whereas pits with similar sizes were observed for the samples immersed in solutions with 0.005 and 0.01 mol L-1 of NaCl. Moreover, the maximum depth of attack was observed for the sample immersed in 0.001 mol L-1 NaCl. These results were in agreement with the scanning ion-selective electrode technique (SIET) maps which showed stronger acidification on the sample exposed to 0.001 mol L-1 NaCl solution.

Absorption of Toluene Using Deep Eutectic Solvents: Quantum Chemical Calculations and Experimental Investigation

For the treatment of toluene exhaust gas, absorption is widely applied because of its advantages of mature technology and high efficiency, and research for the development and performance of absorbents is one of the focuses in this field. Deep eutectic solvents (DESs), which are emerging as efficient green solvents, were introduced as the toluene absorbent in this work. The effects of the structures and compositions of hydrogen bond acceptors (HBAs) and hydrogen bond donors (HBDs) on toluene affinities were explored. It was found that both the HBAs and HBDs with longer alkyl chains have higher affinities to toluene; in addition, the solubility of toluene in DESs increases with the increase of the ratio of long-chain-fatty-acid HBDs. Tetraethylammonium chloride (TEACl) and oleic acid (OA) were selected as the HBA and HBD, respectively, in a molar ratio of 1:3 to form DES TEACl-OA. A quantum chemistry method was adopted to study the noncovalent interactions between molecules to gain insights into the microscopic mechanism. Results demonstrated that weak hydrogen bonds (HBs) dominated by the dispersion attraction are formed between toluene and other systems, while strong HBs of the nature of the electrostatic interaction are formed between the HBA and HBD. In addition, the interaction between toluene and DES is stronger than that between toluene molecules, which is the essential reason for toluene removal by TEACl-OA. Furthermore, the excellent absorption performance of the DES was confirmed by experiments of solubility and dynamic absorption, in which Henry’s law constant at 298.2 K is 2.53 Pa.m(3)/mol and the removal efficiency in the first 10 min of the continuous bubbing absorption process can reach 99.7%. The proposed DES TEACl-OA is proved to be a promising solvent for toluene absorption; furthermore, the theoretical research and experimental data are significant for the development of DES absorbents and revealing the absorption mechanism on a molecular scale.

An Additional Ca2+ Binding Site Allosterically Controls TMEM16A Activation

Calcium (Ca2+) is the primary stimulus for transmembrane protein 16 (TMEM16) Ca2+-activated chloride channels and phospholipid scramblases, which regulate important physiological processes ranging from smooth muscle contraction to blood coagulation and tumor progression. Binding of intracellular Ca2+ to two highly conserved orthosteric binding sites in transmembrane helices (TMs) 6-8 efficiently opens the permeation pathway formed by TMs 3-7 Recent structures of TMEM16K and TMEM16F scramblases revealed an additional Ca2+ binding site between TM2 and TM10, whose functional relevance remains unknown. Here, we report that Ca2+ binds with high affinity to the equivalent third Ca2+ site in TMEM16A to enhance channel activation. Our cadmium (Cd2+) metal bridging experiments reveal that the third Ca2+ site’s conformational states can profoundly influence TMEM16A’s opening. Our study thus confirms the existence of a third Ca2+ site in TMEM16A, defines its functional importance in channel gating, and provides insight into a long-range allosteric gating mechanism of TMEM16 channels and scramblases.

Characterisation and antioxidant activity of glycated casein hydrolysate with xylose: Impacts of zinc sulphate and cupric chloride

Impacts of zinc sulphate and cupric chloride on characteristics and antioxidant capacities of glycated products (GPs) derived from casein hydrolysate (CH) and xylose were studied. The browning degree of xylose-CH GPs was the largest at zinc sulphate addition of 15 mg L-1, while its browning degree increased with cupric chloride extended from 0 to 15 mg L-1. Loss of free amino groups, fluorescence intensity and the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging capacity of xylose-CH GPs increased with the increase of cupric chloride addition, but loss of amino groups, fluorescence intensity and DPPH radical scavenging capacity were largest at the zinc sulphate addition of 15 mg L-1. The addition of zinc sulphate and cupric chloride promoted production of higher and smaller molecular substances in xylose-CH GPs and CH. Therefore, zinc sulphate and cupric chloride promoted glycated reaction of xylose and CH and enhanced antioxidant activity of xylose-CH GPs. (C) 2020 Elsevier Ltd. All rights reserved.

Electrocatalytic activity of metal-doped SnO2 for the decomposition of aqueous contaminants: Ta-SnO2 vs. Sb-SnO2

Sb-doped SnO2 (ATO) is one of the most widely used electrocatalyst anodes for the oxidation of water and wastewater. This study synthesizes Ta(V)-doped SnO2 (TTO) electrocatalysts as alternatives to ATO and systematically examines their electrocatalytic activity for the decomposition of organic substrates in various electrolyte solutions. The as-synthesized ITO exhibits the highest activity for the decomposition of phenol, N,N’-dimethyl-4-nitrosoaniline, and rhodamine-B at a Ta doping level of similar to 1%. The optimized TTO exhibits a higher activity for the decomposition of phenol than ATO in a chloride solution and a lower activity than ATO in a sulfate solution. Electron paramagnetic resonance analysis reveals that a relatively larger production of reactive oxygen species is achieved with ATO, whereas a larger production of reactive chlorine species is obtained with TTO. In the durability tests, both electrodes favor an alkaline condition (pH 12.8) over acidic and neutral conditions (pH 1.5 and 6.2, respectively), and Ta-SnO2 is less stable than Sh-SnO2 over the full pH range. Additionally, solid-state and electrochemical surface characterizations are carried out.

In situ Fe3O4 nanoparticles coating of polymers for separating hazardous PVC from microplastic mixtures

Poly(vinyl chloride) (PVC) poses great challenges to the recycling of plastic wastes since it highly deteriorates the properties of other plastics and induces the formation of hazardous chlorinated dioxins and furans. For the first time, we developed a novel hydrophilization method of polymers, the in situ magnetite (Fe3O4) nanoparticles (NPs) coating, to facilitate the flotation separation of PVC from microplastic mixtures. A homogeneous Fe3O4 NPs layer was selectively fabricated on the surface of non-PVC microplastics via a facile in situ coprecipitation method. This obviously decreased the contact angle of non-PVC microplastics by approximately 30 degrees due to the plenty of hydroxyl groups on the surface of Fe3O4 NPs. However, the fabrication was not observed on the surface of PVC due to the weak interaction between Fe3+/Fe2+ and the surface of PVC. In this regard, the application of in situ Fe3O4 NPs coating in the flotation separation of PVC was systematically optimized using Box-Behnken design of response surface methodology. Quadratic models were generated to predict the floatability of microplastics, ascertain the effect of independent and interacted parameters, and numerically optimize the separation efficiency. Under optimum conditions, the Removal rate, Purity, and Recovery of PVC were 100.0%, 99.6%, and 100.0%, respectively. This study provides novel insights into the surface hydrophilization of polymers and shows promising prospects for facilitating the recycling of plastic wastes.

Direct comparison of gamma, electron beam and X-ray irradiation effects on single-use blood collection devices with plastic components

Effective sterilization methods for single-use devices are a growing need for the medical industry. Concerns with safety, throughput and source availability, however, prompt prudent contingency planning for gamma irradiation of devices suited for radiation sterilization. Electron beam (e-beam) and X-ray represent two alternatives to gamma radiation if they can be confirmed to be compatible with sterilization of the devices. To address this question, the effects of sterilization-relevant doses of e-beam and X-ray radiation are directly compared to the effects of gamma radiation using two prototypical commercial devices currently sterilized using cobalt-60 gamma radiation. These devices include components that comprise six distinct polymer materials commonly used in the medical device industry. The devices investigated are the Becton, Dickinson and Company (BD) Vacutainer (TM) Plus tube, comprised of low-density polyethylene, chlorobutyl rubber, and polyethylene terephthalate components; and the BD Vacutainer (TM) Push Button Blood Collection Set, containing polypropylene, polyolefin elastomer, and polyvinyl chloride components. Changes in functionality, discoloration and select mechanical properties of components of each device were measured following exposure to targeted doses of 15, 35, 50 and 80 kGy. A statistical analysis was performed to determine if the effects of e-beam or X-ray radiation differ from the effects of gamma radiation for the properties considered. No devices were found to fail the functional performance tests at any of the doses considered. Small, but statistically significant differences were observed in device discoloration from e-beam, X-ray and gamma radiation following processing for certain materials at certain dose levels. Both e-beam and X-ray irradiation appear as viable alternatives to gamma irradiation for sterilization of the medical devices and materials considered.

Synthesis, characterization and desalination study of polyvinyl chloride-co-vinyl acetate/cellulose acetate membranes integrated with surface modified zeolites

Novel mixed matrix membranes of polyvinyl chloride-co-vinyl acetate/cellulose acetate (PVCA/CA) infused with nano-particles of both pristine zeolite (p-zeolite) and 3-aminopropyl triethoxysilane (APTS) functionalized zeolite (f-zeolite) were synthesized by dissolution casting method for desalination application. MMMs were then characterized using FTIR, SEM, contact angle and DMA analysis. FTIR and TGA analysis were also carried out for zeolite particles to confirm the surface functionalization. The loading effect of zeolite (1, 3 and 5 wt. %) and the impact of APTS functionalization on dispersion, morphological structure, thermo-mechanical properties and hydmphilicity were also analyzed. Desalination performance of the membranes was evaluated using 2000 ppm NaCl solution at 6 bar pressure. SEM analysis demonstrated that APTS functionalization improved the uniformity of the zeolite nano-particles in the membrane and a noticeable reduction in undesirable microscopic voids. Higher hydmphilicity was attained with the inclusion of f-zeolite nanoparticles, as confirmed by contact angle measurement analysis. It was found that the membrane infused with 5 wt. % of f-zeolite exhibited substantial improvements in storage modulus, glass transition temperature and cross-link density. Membranes infused with f-zeolite demonstrated enhanced transport mechanism without showing trade-off between water flux and salt rejection. In particular, inclusion of 5 wt. % f-zeolite, resulted in achieving the highest salt rejection of 99.56% with water flux increment of -24% in comparison to the neat PVCA/CA membrane. Finally, the membranes were tested for anti-fouling properties using flux recovery ratio test. Thus, the newly developed PVCA/CA membranes embedded with APTS f-zeolite can be exploited for high performance desalination applications.

Production of calcium magnesium phosphate microspheres in a water-in-oil-in-water dispersion

Interfacial reaction in a multiple water-in-oil-in-water dispersion, or double emulsion, was carried out to produce microspheres in a system containing calcium, magnesium and phosphate ions. The inner aqueous phase comprised dipotassium hydrogen phosphate solution. The outer aqueous phase comprised calcium chloride and magnesium chloride solution, in which polyoxyethylene(20) sorbitan monolaurate was dissolved as a stabiliser for the oil droplets. The oil phase comprised cyclohexane, in which sorbitan monooleate was dissolved as a stabiliser for the inner aqueous droplets. Hollow microspheres were generated by this reaction, where the surface state changed from rough to smooth with increasing magnesium content in the outer aqueous phase. The morphology of the primary particles was altered from sheet-like to spherical. The crystalline phase was identified as calcium-deficient hydroxyapatite at lower magnesium contents and as magnesium-substituted p-tricalcium phosphate at higher magnesium contents by considering the lattice parameters and ionic ratio of the products. The existence of an amorphous phase was detected, irrespective of the magnesium content. The magnesium content in the product was lower than that of the reactant solution, suggesting that magnesium was eliminated through a purification process accompanied by crystallisation of the amorphous phase. The location of the reaction site and how the outer aqueous phase is transported thereto were discussed by comparison of the magnesium content of the products formed by the solution reaction with that of the product from the interfacial reaction.
