Crosslinked nanocomposite membranes were developed by in situ reaction of dextran and soy protein isolate nanoparticles (nanosoy). The formation of a covalent bond between the reducing end of dextran and the amine groups of nanosoy (NS) leads to the in situ crosslinking. The NS particles employed for this study were 5–15 nm in size, as observed in the high‐resolution transmission electron microscopy micrograph. Glycerol addition assisted in the plasticization of the membranes, thus improving their flexibility and handling features. The effect of polymer composition on the extent of crosslinking, morphology, and flexibility of the films was investigated. Field emission scanning electron microscopy and atomic force microscopy revealed that single‐phase, homogeneous membranes are obtained within a specific composition of dextran/NS/glycerol (D/NS/G). The degree of crosslinking was evaluated by Raman spectroscopy and gel content measurements. The crystallinity of the D/NS/G membranes was found to increase monotonically as the NS content in the blend increased. An increase in tensile strength and decrease in Young's modulus was observed with an increase in NS content up to 28%, due to the reinforcing effect of NS and the plasticizing effect of glycerol playing roles simultaneously in the system. The reinforcing effect of the NS assisted in the formation of high‐strength nanocomposite membranes. Furthermore, they were characterized to analyze their thermal behavior. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017 , 134, 44655. 相似文献

Crop Wild Relatives (CWRs) form a comprehensive gene pool that can answer the queries related to plant domestication, speciation, and ecological adaptation. The genus ‘Oryza’ comprises about 27 species, of which two are cultivated, while the remaining are wild. Here, we have attempted to understand the conservation and diversification of the genes encoding Cystathionine β-synthase (CBS) domain-containing proteins (CDCPs) in domesticated and CWRs of rice. Few members of CDCPs were previously identified to be stress-responsive and associated with multiple stress tolerance in rice. Through genome-wide analysis of eleven rice genomes, we identified a total of 36 genes encoding CDCPs in O. longistaminata, 38 in O. glaberrima, 39 each in O. rufipogon, O. glumaepatula, O. brachyantha, O. punctata, and O. sativa subsp. japonica, 40 each in O. barthii and O. meridionalis, 41 in O. nivara, and 42 in O. sativa subsp. indica. Gene duplication analysis as well as non-synonymous and synonymous substitutions in the duplicated gene pairs indicated that this family is shaped majorly by the negative or purifying selection pressure through the long-term evolution process. We identified the presence of two additional hetero-domains, namely TerCH and CoatomerE (specifically in O. sativa subsp. indica), which were not reported previously in plant CDCPs. The in silico expression analysis revealed some of the members to be responsive to various abiotic stresses. Furthermore, the qRT-PCR based analysis identified some members to be highly inducive specifically in salt-tolerant genotype in response to salinity. The cis-regulatory element analysis predicted the presence of numerous stress as well as a few phytohormone-responsive elements in their promoter region. The data presented in this study would be helpful in the characterization of these CDCPs from rice, particularly in relation to abiotic stress tolerance. 相似文献

The l -type amino acid transporter 1 (LAT1, SLC7A5) imports dietary amino acids and amino acid drugs (e. g., l -DOPA) into the brain, and plays a role in cancer metabolism. Though there have been numerous reports of LAT1-targeted amino acid-drug conjugates (prodrugs), identifying the structural determinants to enhance substrate activity has been challenging. In this work, we investigated the position and orientation of a carbonyl group in linking hydrophobic moieties including the anti-inflammatory drug ketoprofen to l -tyrosine and l -phenylalanine. We found that esters of meta-carboxyl l -phenylalanine had better LAT1 transport rates than the corresponding acylated l -tyrosine analogues. However, as the size of the hydrophobic moiety increased, we observed a decrease in LAT1 transport rate with a concomitant increase in potency of inhibition. Our results have important implications for designing amino acid prodrugs that target LAT1 at the blood-brain barrier or on cancer cells. 相似文献

In the present paper, the hybrid meshfree method with parallel algorithm has been implemented to simulate natural convection inside a wavy square enclosure with a line heat source placed on the right vertical wall of the cavity. The fluid is assumed to be a -waterbased nanofluid where single-phase model is used in two dimensions. The computations are performed for variation of the Rayleigh number, Hartmann number, positions of the heat source as well as size of the heat source. The results are shown in terms of streamlines, isotherms, and Nusselt numbers. Such problems have direct applications for effective cooling or heating of the enclosures with the heat sources. 相似文献

Layered 2D materials serve as a new class of substrates for templated synthesis of various nanomaterials even with highly dissimilar crystal structures; thus overcoming the lattice constraints of conventional epitaxial processes. Here, molybdenum disulfide (MoS2) is used as a prototypical model substrate for oriented growth of in‐plane Au nanowires (NWs) despite the nearly 8% lattice mismatch between MoS2 and Au. Au NWs on the MoS2 surface are oriented along three symmetrically equivalent directions within the substrate arising from the strong Au–S binding that templates the oriented growth. The kinetics of the growth process are explored through experiments and modeling. Strong charge transfer is observed between Au NWs and MoS2, resulting in degenerate p‐doping of MoS2. 相似文献
