Aqueous phase behavior of the PEO-containing non-ionic surfactant C12E6: A molecular dynamics simulation study

Hypothesis: Non-ionic surfactants containing polyethylene oxide (PEO) chains are widely used in drug formulations, cosmetics, paints, textiles and detergents. High quality molecular dynamics models for PEO surfactants can give us detailed, atomic-scale information about the behavior of surfactant/water mixtures. Simulations: We used two molecular dynamics force fields (FFs), 2016H66 and 53A6(DBW), to model the simple non-ionic PEO surfactant, hexaoxyethylene dodecyl ether (C12E6). We investigated surfactant/water mixtures that span the phase diagram of starting from randomly distributed arrangements. In some cases, we also started with prebuilt, approximate models. The simulations results were compared with the experimentally observed phase behavior. Findings: Overall, this study shows that the spontaneous self-assembly of PEO non-ionic surfactants into different colloidal structures can be accurately modeled with MD simulations using the 2016H66 FF although transitions to well-formed hexagonal phase are slow. Of the two FFs investigated, the 2016H66 FF better reproduces the experimental phase behavior across all regions of the C12E6/water phase diagram. (C) 2020 Elsevier Inc. All rights reserved.

Recent advances in high performance conducting solid polymer electrolytes for lithium-ion batteries

Lithium-ion batteries (LIBs) as an important energy storage technology have found more and more applications in electric vehicles, electronic devices as well as grid energy storage systems. However, due to the safety issues from the flammability of combustible organic liquid electrolytes, recently solid polymer electrolytes (SPEs) have attracted more interest. Conventional SPEs are dual-ion conductors where both anions and cations possess slightly free movement and favor the concentration polarization phenomena, which may reduce their performances and lifetime. To overcome these issues, the conducting solid polymer electrolytes (CSPEs) are developed where the anions are linked via covalent bonds to the polymeric and inorganic backbones or anion acceptors, which may greatly accelerate the transportation of lithium ions and increase their lithium-ion transference number (LTN) and ionic conductivity as well as reduce the formation of concentration polarization and Li dendrite growth. Herein, a comprehensive overview of the latest development in CSPEs for LIBs is described, which emphasizes the correlations among their synthetic strategies, structures, and electrochemical performances. Finally, the state of the art, future perspectives, and core challenges are provided for designing the next generation of CSPEs in high performance LIBs.

Hyperbranched polymers containing epoxy and imide structure

A challenge to polymer scientists is to design new materials with superior overall performance in heat-resistance, cold-resistance, strength, and toughness. Here we report the synthesis of hyperbranched polymers containing epoxy and imide structure (EHPI-n, n = 6, 12, and 24) with various molecular weights and degrees of branching using a new synthetic diimide dicarboxylic acid. EHPI-n significantly decreases the gelation time and accelerates the curing of EHPI-n/diglycidyl ether of bisphenol-A (DGEBA). Both EHPI-6 and EHPI-12 significantly reduce the viscosity, activation energy, and average particle size of EHPI-n/DGEBA blends due to the disentangling function and compatibility of the EHPI-n. The toughness property, including elongation at break, impact strength, critical strain energy value (G(IC)) and critical stress intensity factor (K-IC) of 12 wt % EHPI-12/DGEBA composites are improved over the neat DGEBA, by 144.72 %, 197.9 %, 168.4 % and 72.6 %, respectively, while their mechanical properties, including tensile strength, storage modulus and flexural strength are enhanced by 61.2 %, 89.9 %, 44.2 %. The heat-resistant index and beta-relaxation peak temperatures of the composites are improved 14 degrees C and 15 degrees C, respectively, indicating both outstanding high-temperature resistance and outstanding low-temperature resistance. The simultaneous improvement on multiple performances is attributable to an in-situ homogeneous reinforcing and toughening mechanism, which is explained by free volume fraction, microstructure and surface micrograph. The EHPI-n present great potential as advanced materials for aerospace and wind turbine.

Development of a sensitive MEKC-LIF method for synthetic cathinones analysis

Synthetic cathinones are phenylalkylamine compounds related to natural cathinone from Catha edulis leaves. Due to their sympathomimetic effects comparable to common illicit drugs, these substances are mainly drugs of abuse and constitute the second most frequently seized group of new psychoactive substances. In order to ensure their regulation and to promote public health, reliable analytical tools are required to track these substances. In the present study, we developed a CE hyphenated to laser-induced fluorescence detection method to demonstrate its suitability to perform fast and cost-effective synthetic cathinones analysis. Fourteen compounds including isobaric compounds and position isomers were selected to encompass the large panel of chemical structures. To separate the FITC-labeled analytes (presenting the same negative charge and close mass to charge ratios), MEKC separation mode was selected. Method selectivity was not suitable using common surfactants. In this context, alkyl polyethylene glycol ether surfactants were successfully used as neutral surfactant to overcome this analytical challenge. The effect of surfactant nature on separation performances and migration behaviors of the analytes was also studied. Optimal BGE composition included 75 mM borate buffer at pH 9.3 and 0.4 mM of C12E10 surfactant. Final MEKC separation conditions were proposed to analyze a large panel of synthetic cathinones. This method helped to reach a sensitivity with LOD from 0.1 to 0.4 nM (pg/mL order).

Superacid sulfated SnO2 doped with CeO2: A novel inorganic filler to simultaneously enhance conductivity and stabilities of proton exchange membrane

Towards the breaking of the trade-off’ between proton conductivity and stabilities of sulfonated poly(aryl ether sulfone) (SPAES)-based proton exchange membranes, a strategy of compositing with the superacids of sulfated SnO2 (ST) and SnO2-xCeO(2) (CSTx) is designed and carried out. The superacids of ST and CSTx have been synthesized by sulfonation of SnO2 with sulfuric acid and subsequently doped with CeO2. By the solution casting approach, the composite membranes are obtained in a homogenous state and show excellent mechanical strength, thermal, dimensional and chemical stability. ST or CSTx in the composite membranes provides excess active sites and forms additional proton-conducting channels by a network of hydrogen bonds. Although with low IEC levels, all the composite membranes show larger water absorption and proton conductivity than the control SPAES membrane. As a result, the SPAES-2C5T3 membrane achieves a power output of 673.6 mW/cm(2) at 80 degrees C, which is higher than the control membrane (481.8 mW/cm(2)). The durability of the SPAES-2C5T3 membrane under accelerated stress test conditions is significantly enhanced compared to the control SPAES membrane, and the aged SPAES-2C5T3 membrane exhibits lower hydrogen crossover and better cell performance than the aged control SPAES membrane.

Investigation of fluorinated ether-containing electrolytes for high energy-density nickel-rich LiNi0.8Co0.1Mn0.1O2 electrodes

Nickel-rich LiNixCoyMn1-x-yO2 (x >= 0.6, NCM) materials and in particular LiNi0.8Co0.1Mn0.1O2 (NCM811) are considered as the most potential candidates for utilization in the next-generation of high-energy-density lithium-ion batteries (LIBs). However, the NCM811 materials encounter capacity fading during cycling, originating mainly from detrimental positive electrode-electrolyte interface changes. Here, to decrease electrolyte oxidative decomposition during NCM811 cycling process, we select a partially fluorinated ether, such as 1,1,2,2- tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) and 1,1,1,3,3,3-hexafluoroisopropyl methyl ether (HFPM), as a co-solvent for fluoroethylene carbonate (FEC)-based electrolytes and investigate theirs physicochemical and electrochemical performances in great details for their applications in NCM811 materials. Compared to the FEC-based electrolyte solution without a fluorinated ether co-solvent, the electrolytes with a fluorinated ether co-solvent exhibits an obviously improved cycling and rate properties of the Li/NCM811 cells cycled between 2.7 and 4.3 V. This work also shows that the TTE solvent is prone to both suppress the decomposition of FEC to stabilize the FEC-based electrolyte solution, and be reduced and form a stable interface layer in the highly reactive Li surface.

Atmospheric concentrations and temporal trends of polychlorinated biphenyls and organochlorine pesticides in the Arctic during 2011-2018

Passive air samples were deployed in Ny-Alesund and London Island (Svalbard, High Arctic) annually for seven years (2011-2018) to investigate concentrations, temporal trends and potential sources of selected persistent organic pollutants (POPs). Nine polychlorinated biphenyls and twelve organochlorine pesticides were detected in all samples, with 3,3′-dichlorobiphenyl (PCB-11) being the prevalent congener. Concentrations of most compounds were declining. The ratio of the alpha- and gamma-isomer of hexachlorocyclohexane (HCH) in Arctic air was comparable with that in technical HCH mixtures, but higher than that in the atmosphere of other countries, thereby indicating the impact of historical use as well as the possible photoisomerization of the gamma- into the alpha-isomer. The parent dichlorodiphenyltrichloroethane (DDT) was always less abundant than its degradation products dichlorodiphenylethylene (DDE), indicative of the impact of aged DDT sources in the Arctic atmosphere. However, o,p’-/p,p’-DDT ratios suggest only a minor contribution of dicofol-type DDT. A slightly declining temporal trend of the trans-chlordane/cis-chlordane ratio indicated the impact of secondary sources. The atmospheric distribution of the investigated POPs in the Arctic was mainly attributed to long-range atmospheric transport, whereas the influence of human activities from the scientific research stations was minor.

Two Cu(ii)-based coordination polymers: Dye degradation and important values on the later recovery of fracture patients by activating the WNT signaling pathway

Through utilizing the mixed-ligand method, two novel coordination polymers {[Cu(bpdc)(bpbenz)]}(n), (1, H(2)bpdc = [1,1′-biphenyl]-4,4′-dicarboxylic acid, bpbenz = 1,4-bis(4-pyridyl)benzene) and {[CR(bpdc)(bide)(2)]}(n) (2, bide = 4,4′-bis(imidazolyl)diphenyl ether) with structural diversity have been synthesized via Cu(NO3)(2)center dot 3H(2)O reacting with the rigidity bicarboxylic ligands H(2)bpdc in the existence of the distinct nitrogen-donor co-ligands. The photocatalytic degradation performance of complex 1 to distinct dye contaminants (MO, RhB and MB) was assessed. The results confirm that the photocatalytic degradation efficiency of complex 1 to the MB is the highest (MO 86.2%, RhB 85.7% and MB 92.1%). Their application values on the later recovery of fracture patients were then evaluated. The real time RT-PCR method was conducted to assess the osterix and n=2 relative expression levels in the mesenchymal stem cells (MSCs). The western blot method was implemented and the WNT (WNT is a fusion of two terms, wg derived from the Drosophila gene wingless (wg) and int derived from the proto-oncogene integration, which is the mammalian homolog of wg) protein expression levels were assessed.

Accumulation and influencing factors of novel brominated flame retardants in soil and vegetation from Fildes Peninsula, Antarctica

The concentrations and distributions of nine novel brominated flame retardants (NBFRs) were analyzed in soil, lichen (Usnea aurantiaco-atra), and moss (Sanionia uncinata) samples collected from the Chinese Antarctic Great Wall Station and surrounding Fildes Peninsula area in west Antarctica. Total NBFR concentrations ranged from 61.2-225 pg/g dry weight (dw) in soil, 283-1065 pg/gdw in moss, and 135-401 pg/g dw in lichen, respectively. Decabromodiphenyl ethane (DBDPE) was the dominant NBFR in all samples, accounting for 652%, 50.1%, and 72.4% of cumulative NBFR concentration in soil, moss, and lichen, respectively. The concentrations of NBFRs in plant samples were higher than those in soil, which may be related to plant bioaccumulation. Significant log/log-linear correlations (p < 0.05) were found between the concentrations of BEHTEBP and total organic carbon (TOC) in soil, and between DBDPE and lipid content in mosses, indicating that TOC and lipid content potentially affect certain NBFRs in Antarctic soil and moss. This study presents the first report on NBFR contamination in soil and various vegetation in Antarctica. (C) 2020 Elsevier B.V. All rights reserved.

Atomistic insights into friction and wear mechanisms of graphene oxide

Graphene oxide (GO) is a promising solid lubricant used as a protective coating to reduce friction, while a detailed atomic scale understanding about its tribological behavior is required. In this study, ReaxFF reactive molecular dynamics simulations are used to explore the friction and wear mechanisms of GO. At low load, the structure of GO can be tailored via the tribochemical induced conversion from graphene oxide to graphene (GO-to-Gr), achieving low friction during the sliding process. The effects of multiple sliding and system temperature on the GO-to-Gr conversion are considered. At high load, wear of GO at the nanoscale is characterized by the emergence of the C-C bond and C-O bond breaking, both of which are related to the transformation from the epoxide groups to the ether groups. Furthermore, we show that decreasing the concentration of epoxide groups is a feasible method to enhance wear resistance of GO.
