High sensitive and fast response humidity sensor based on polymer composite nanofibers for breath monitoring and non-contact sensing

A rapid and stable polymeric humidity sensor is demonstrated using electrospun sulfonated poly (ether ether ketone)/polyvinyl butyral (SPEEK/PVB) composite nanofiber and applied in breath monitoring and non-contact sensing for the first time. First, SPEEK was fabricated into thin film sensor by drip casting and nanofiber sensor by electrospinning, respectively. By comparing the humidity sensing characteristics of the two sensors, it is found that the hysteresis and response/recovery time of the nanofiber humidity sensor have been significantly improved. To further improve its sensing performance, we incorporated different contents of polyvinyl butyral (PVB) to the electrospinning solution to prepare SPEEK/PVB composite nanofiber humidity sensors. The morphology and diameter of nanofibers with different PVB contents were observed by Scanning Electron Microscope. The composite nanofiber humidity sensor exhibited high sensitivity, wide working range of relative humidity, small hysteresis (2.68 %), fast response time (<1 s), rapid recovery time (5 s) and stable sensing performance when the ratio of SPEEK to PVB is 1:3. In addition, the breath monitoring and non-contact sensing performance of SPEEK/PVB = 1:3 composite nanofiber humidity sensor was also studied. This work indicates that electrospun SPEEK/PVB nanofibers have good application prospects as humidity sensors for real-time humidity monitoring and non-contact sensing devices.

Removal of phenolic contaminants from water by pervaporation

The removal of phenolic compounds from water streams is of great importance due to their high toxicity, car-cinogenicity, and bioaccumulation in food chains. In this study, the separation of four representative phenolic compounds (including phenol (PhOH), p-cresol (MePhOH), p-chlorophenol (ClPhOH), and p-nitrophenol (O2NPhOH)) from aqueous solutions by pervaporation using poly(ether-b-amide) (PEBA) membrane was studied. The effects of feed concentration (up to 0.6 wt%) and operating temperature (30-70 degrees C) on the separation performance were investigated. While the permeation fluxes of phenolic compounds increased at higher feed concentrations, the increase in the flux was less than proportional, leading to a decrease in the enrichment factor. It was also shown that both the permeation flux and the enrichment factor increased with an increase in temperature. However, the permeabilities of the phenolic compounds in the membrane were impacted differently. Of particular interest were the coupling effects of co-existing phenolic compounds due to permeant-permeant interactions, which were found to be significant in permeation of multiple phenolic compounds that were relevant to practical applications. The permeation of PhOH, MePhOH and ClPhOH was all affected adversely by the presence of additional phenolic compounds in the feed solution, while the opposite was true for the permeation of slow-permeating O2NPhOH. Depending on the specific phenol solute, high-purity phenol crystals could be produced from the phenol-enriched permeate via de-sublimation in the cold trap, which was of particular interest for practical applications.

Optimization of Hexavalent Chromium Biosorption by Shewanella putrefaciens Using the Box-Behnken Design

Cr(VI) is a ubiquitous pollutant that poses a serious threat to human health. Recently, the use of microorganisms to adsorb heavy metals has attracted research attention. However, there are few studies on the biosorption of Cr(VI) by Shewanella putrefaciens, which is a metal-reducing bacterium. In this paper, single-factor experiments were designed to investigate the effect of hexavalent chromium by Shewanella putrefaciens, and response surface methodology (RSM) based on the Box-Behnken design (BBD) was performed to study the Cr(VI) biosorption behavior of Shewanella putrefaciens. The coefficient of determination (R-2 = 0.811 for Cr(VI)) and probability value (P < 0.05) demonstrated significance for the obtained regression model. The results showed that the model was suitable for experimental data, and the maximum Cr(VI) removal efficiency by Shewanella putrefaciens was 85.68% under the optimum conditions of a contact time of 16.57 h, pH value of 8, and biomass dosage of 0.42 g/L, which were verified by additional experiments. ANOVA and 3D response graph analysis showed that the variables with significant influences were pH and temperature. In addition, scanning electron microscopy (SEM) results demonstrated that after biosorption of Cr(VI) by Shewanella putrefaciens, granular complexes attached to rough cell surfaces were observed. Furthermore, Fourier transform infrared spectroscopy (FT-IR) analysis showed that the distribution of Cr(VI) on the cell surface was related to the carboxyl, ether, amide, hydroxyl, and phosphoric acid groups of Shewanella putrefaciens. This study is useful to explore the process and mechanism of heavy metal adsorption by Shewanella putrefaciens and provide new ideas for the microbial remediation of metal pollution in water.

Brominated flame retardants and heavy metals in common aquatic products from the pearl river delta, south china: Bioaccessibility assessment and human health implications

Aquatic products are an important source of environmental pollutants to humans. This study was conducted to assess the bioaccessibility of selected brominated flame retardants and heavy metals in common aquatic products from the Pearl River Delta, South China, as well as associated human health risks. Based on a questionnaire survey, ten of the most consumed aquatic products were collected from local markets. The bioaccessibility of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCDDs), and heavy metals was assessed using an in vitro gastrointestinal model. Bioaccessibility of heavy metals (33.0-84.0%) and HBCDDs (38.5-68.4%) was significantly higher than that of PBDEs (13.4-65.4%). Total non-carcinogenic and carcinogenic risks from heavy metal consumption were much higher than the threshold values due to excessive abundances of arsenic in shellfish (HQ = 2.45, CR = 1.1 x10(-3)). Furthermore, middle-aged populations and females were subjected to greater health risks due to different intakes of aquatic products among age and gender groups. Significant difference in bioaccessibility among analytes indicated that bioaccessibility of pollutants is non negligible in health risk assessment. This is the first study systematically investigating health risks of aquatic products consumption and concludes that shellfish is a great cause for concern for the PRD residents.

Novel highly efficient branched polyfluoro sulfonated polyimide membranes for application in vanadium redox flow battery

Branched polyfluom sulfonated polyimide (BPFSPI) membranes with different degree of branching and degree of sulfonation are designed and prepared for application in vanadium redox flow battery (VRFB). The optimized BPFSPI-10-50 membrane exhibits a similar proton conductivity (2.94 x 10(-2) S cm(-1)) as that of the commercial Nafion 212 membrane (3.20 x 10(-2) S cm(-1)) and a much higher membrane selectivity (3.16 x 10(5) S min cm(-3)) than Nafion 212 membrane (0.42 x 10(5) S min cm(-3)). Meanwhile, BPFSPI-10-50 membrane is durable in V(V) + H2SO4 solutions for more than 30 d. Both coulomb efficiency (CE) and energy efficiency (EE) of BPFSPI-10-50 membrane are higher than those of Nafion 212 membrane (CE: 94.2-98.9% vs 73.9-94.9%, EE: 68.0-86.9% vs 67.7-77.9%) in VRFB (40-200 mA cm(-2)) test. Besides, BPFSPI-10-50 membrane displays slower self-discharge rate and excellent discharge capacity retention compared to Nafion 212 membrane. Furthermore, the VRFB with BPFSPI-10-50 membrane shows very stable CE and EE (>98% and 76%) over 200 charge-discharge cycles. Accordingly, the BPFSPI-10-50 membrane with superior cost-performance ratio has an outstanding prospect for application in VRFB.

Reduction-responsive double hydrophilic block copolymer nano-capsule synthesized via RCMP-PISA

A double hydrophilic block copolymer (DHBC) vesicle was synthesized via an organocatalyzed living radical polymerization, i.e., reversible complexation mediated polymerization (RCMP). RCMP was combined with polymerization-induced self-assembly (PISA) to give an amphiphilic block copolymer vesicle comprising hydrophilic poly(poly(ethylene glycol) methyl ether methacrylate) (PPEGMA) and hydrophobic poly(solketal methacrylate) (PSKM). With the incorporation of a crosslinker, i.e., bis(2-methacryloyl)oxyethyl disulfide (BMOD), in the vesicle, and upon the subsequent hydrolysis of the hydrophobic PSKM into hydrophilic poly(glycerol methacrylate) (PGLMA), a stable DHBC vesicle was generated. The vesicle was successfully utilized to encapsulate an external guest molecule. The encapsulated molecule was also released by cleaving the disulfide bond in the crosslinker (BMOD) in the presence of glutathione (in a reductive condition). The present vesicle consists of neutral (not acidic or basic) PEGMA and PGLMA segments and hence has no restriction in the pH range for its use. PPEGMA and PGLMA are also biocompatible. With these properties, the present DHBC vesicle may serve as a useful reduction-responsive container.

Effects of Decabrominated Diphenyl Ether Exposure on Growth, Meat Characteristics and Blood Profiles in Broilers

Simple Summary Decabrominated diphenyl ether (BDE-209) has been widely used in recent decades, and its cumulative toxicity to crops, animals and human beings is attracting increasing attention. In this study, we established broiler models to investigate the effects of BDE-209 exposure at doses of 0, 0.02, 0.4 and 4 mg/kg on growth, carcass traits, meat quality, blood profiles and antioxidant capacity. Our results suggested that BDE-209 exposure altered the blood profiles and carcass traits and exhibited toxicity in liver and kidney functions. Furthermore, BDE-209 increased plasma malondialdehyde (MDA) concentrations and decreased the activities of glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), which implied aggravating oxidant stress and decline of antioxidant capacity in broilers. Decabrominated diphenyl ether (BDE-209) is widely used as a flame retardant and is detected at high levels in the environment. Its toxicities have been reported and have attracted attention. In the present study, broilers were used to determine the response in growth performance, carcass traits, meat quality, blood profiles and antioxidant system to BDE-209 exposure at doses of 0, 0.02, 0.4 and 4 mg/kg. The results showed that BDE-209 exposure at levels of 0.02 or 0.4 mg/kg increased feed intake and decreased feed efficiency. BDE-209 altered the blood profiles, such as reducing the numbers of white blood cells, lymphocytes and neutrophilic granulocytes. As compared with the control, BDE-209 exposure significantly increased abdominal fat percentages of broilers at 64.9-159.5% and adversely affected the selected biochemical indicators, including alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine (CRE), which indicated its toxicity to liver and kidney functions. Moreover, BDE-209 exposure significantly increased plasma malondialdehyde (MDA) concentrations and decreased the activities of glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), which implied aggravating oxidant stress and decline of antioxidant capacity in broilers. In conclusion, our data demonstrated that the environmental pollutant BDE-209 adversely influenced growth performance, increased the deposition of abdominal fat, impaired antioxidant capacity and the immune system and had potential toxicity to the liver and kidney of broilers.

A novel interaction mechanism in lignin pyrolysis: Phenolics-assisted hydrogen transfer for the decomposition of the beta-O-4 linkage

Pyrolysis of lignin involves complex unimolecular decomposition and bimolecular interaction mechanisms. Unimolecular decomposition of lignin model compounds has been widely investigated, while bimolecular interactions are far from well elucidated. Currently, only two radical reaction-based interactions, i.e., hydrogen abstraction and hydrogen-bond-induced homolysis mechanisms, have been proposed to explain the interactions in the lignin pyrolysis process, which ignores the concerted reaction-based interactions involving the pyrolytic products of lignin. Particularly, a large number of phenolics are produced in the pyrolysis of lignin, which can further affect the concerted pyrolysis reactions of lignin. In the present work, a novel interaction mechanism, phenolics-assisted hydrogen transfer (phenolics-AHT) pro cess for the concerted reactions, is confirmed and carefully investigated. Phenylethyl phenyl ether (PPE), a typical beta-O-4 lignin dimer, is used as the model compound to reveal the phenolics-AHT mechanism in the lignin pyrolysis system. Density functional theory (DFT) calculation, electrostatic potential (ESP) analysis, and fast pyrolysis experiment results are combined to reveal that the phenolic products participate in the hydrogen transfer process of the concerted Maccoll elimination reaction by means of their phenolic hydroxyl structures and significantly reduce the energy barrier, thus promoting the cleavage of the beta-O-4 linkage. On the contrary, phenolics-AHT has no obvious effect on the concerted retro-ene fragmentation. At medium pyrolysis temperatures, the hydrogen transfer processes induced by phenolic products play a more significant role in the dissociation of the beta-O-4 linkage than the hydrogen abstraction induced by radicals, due to the limited amount of free radicals. In addition, DFT calculation results further suggest that decarbonylation, decarboxylation, dehydration, tautomerism, and other concerted reactions can also be promoted by phenolics-AHT.

Parabens in personal care products and indoor dust from Hanoi, Vietnam: Temporal trends, emission sources, and non-dietary exposure through dust ingestion

The occurrence of seven typical parabens was investigated in several types of personal care products (PCPs) sold at supermarkets and in indoor dust samples collected from houses, laboratories, and medical stores in Hanoi, Vietnam. Parabens were frequently detected in PCPs regardless of the paraben indication in their ingredient labels. However, concentrations of parabens in labeled products (median 3280; range 1370-5610 mu g/g) were much higher than those found in non-labeled products (69.4; not detected – 356 mu g/g). Parabens were also measured in indoor dust samples of this study at elevated concentrations, ranging from not detected to 1650 (median 286 ng/g). Levels of parabens in the indoor dust samples collected in 2019 decreased in the order: house > medical store > laboratory dust, however, the difference was not statistically significant. Interestingly, levels of parabens in Vietnamese house dust exhibited an increasing trend over time, for example, mean/median concentrations of parabens in house dust samples collected in 2014, 2017, and 2019 were 245/205, 310/264, and 505/379 ng/g, respectively. Methylparaben was found at the highest frequency and concentrations in both PCPs and indoor dust samples. Mean exposure doses of total parabens through dust ingestion were estimated to be 2.02, 1.61, 0.968, 0.504, and 0.192 ng/kg-bw/d for infants, toddlers, children, teenagers, and adults, respectively. Further studies on the distribution, emission behavior, potential sources, and negative impacts of parabens in different environmental media in Vietnam are needed. (C) 2020 Elsevier B.V.
