Diboron-Catalyzed Regio- and 1,2-cis-alpha-Stereoselective Glycosylation of trans-1,2-Diols

Regio- and 1,2-cis-alpha-stereoselective glycosylations were investigated using 1,2-anhydroglucose donors and trans-1,2-diol sugar acceptors in the presence of a diboron catalyst. The reactions proceeded smoothly to provide the corresponding 1,2-cis-alpha-glycosides with consistently very high stereoselectivity and were regioselectivity controlled by the protecting groups of the acceptor. The present glycosylation method was applied successfully to the efficient synthesis of alpha-1,3-glucan pentasaccharide.

Unusual Nanostructured Morphologies Enabled by Interpolyelectrolyte Complexation of Polyions Bearing Incompatible Nonionic Segments

The nanostructures of polyelectrolyte complexes (PECs) fabricated from a series of rationally designed oppositely charged amphiphilic random copolymers with variable comonomer compositions were studied experimentally in 50:50 (v/v) methanol-H2O mixtures through morpho- logical investigations. Both polycationic [poly(alanine methacryloyloxyethyl ester-co-styrene), P1-P4] and polyanionic [poly(acrylic acid-co-methyl acrylate), P1′-P4′] electrolytes were synthesized via reversible addition-fragmentation chain-transfer (RAFT) copolymerization while maintaining the mole fractions of charge-bearing groups within the range of 50-90%. Unlike polyanions, polycations showed well pronounced pH-responsive behavior owing to pH-induced protonation/deprotonation phenomena of pendant quaternary ammonium groups. On account of this fact, PEC formation with concomitant microphase separation was realized at pH 5.0 when all obtained compositions of both polycations and polyanions were totally soluble. Fine tuning of alanine-derived cationic and anionic acrylic acid compositions confers uncommon morphologies revealed by electron microscopic observations. Intriguingly, a string-of-beads like morphology was observed for PECs prepared with 50 and 60% charged ratios, whereas spherical micelles and vesicles were formed in the case of 70 and 90% ratios, respectively, attributed to the strength of electrostatic interaction and incompatibility of nonionic segments. These fascinating morphologies were further corroborated by computer simulations of two oppositely charged chains within a coarse-grained approach. A diagram of PEC morphologies was constructed depending on the hydrophobic/hydrophilic composition of polyions, fraction of ion-containing groups, and the strength of electrostatic interactions. Observation of these unique morphologies from a single pair of a polyelectrolyte system is scarcely reported in the literature.

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.

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.

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.

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.

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.
