However, to efficiently construct these glyco-assemblies is still a challenge. Herein, we report an efficient technology for the synthesis of glyco-inside nano-assemblies by utilizing RAFT polymerization of a galactose-decorated methacrylate for polymerization-induced self-assembly (PISA). Using this approach, a series of highly ordered glyco-inside nano-assemblies containing intermediate morphologies were fabricated by adjusting the length of the hydrophobic glycoblock and the polymerization solids content. A specific morphology of complex vesicles was captured during the PISA process and the formation mechanism is explained by the morphology of its precursor and intermediate. Thus, this method establishes a powerful route to fabricate glyco-assemblies with tunable morphologies and variable sizes, which is significant to enable the large-scale fabrication and wide application of glyco-assemblies.}, language = {en} } @article{SauterKratzLendlein2013, author = {Sauter, Tilman and Kratz, Karl and Lendlein, Andreas}, title = {Pore-size distribution controls shape-memory properties on the macro- and microscale of polymeric foams}, series = {Macromolecular chemistry and physics}, volume = {214}, journal = {Macromolecular chemistry and physics}, number = {11}, publisher = {Wiley-VCH}, address = {Weinheim}, issn = {1022-1352}, doi = {10.1002/macp.201300062}, pages = {1184 -- 1188}, year = {2013}, abstract = {Open porous foams with identical foam density but different pore-size distributions (bimodal or monomodal) are prepared from a shape-memory polyetherurethane (PEU) by thermally induced phase separation. The shape-memory effect of the two PEU foams is explored by cyclic thermomechanical compression tests and microstructural analysis. The obtained results reveal that the PEU foam with a bimodal pore-size distribution exhibits an increased shape-recovery under stress-free conditions, both on the macro- (foam level) as well as the microscale (pore level). While bimodal pore-size distributions induce microscale bending during compression, buckling occurs in foams with monomodal pore-size distributions, leading to both a reduced and delayed shape recovery.}, language = {en} } @article{GardinerKocyanMotesetal.2013, author = {Gardiner, Lauren M. and Kocyan, Alexander and Motes, Martin and Roberts, David L. and Emerson, Brent C.}, title = {Molecular phylogenetics of Vanda and related genera (Orchidaceae)}, series = {Botanical journal of the Linnean Society}, volume = {173}, journal = {Botanical journal of the Linnean Society}, number = {4}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0024-4074}, doi = {10.1111/boj.12102}, pages = {549 -- 572}, year = {2013}, abstract = {The genus Vanda and its affiliated taxa are a diverse group of horticulturally important species of orchids occurring mainly in South-East Asia, for which generic limits are poorly defined. Here, we present a molecular study using sequence data from three plastid DNA regions. It is shown that Vanda s.l. forms a clade containing approximately 73 species, including the previously accepted genera Ascocentrum, Euanthe, Christensonia, Neofinetia and Trudelia, and the species Aerides flabellata. Resolution of the phylogenetic relationships of species in Vanda s.l. is relatively poor, but existing morphological classifications for Vanda are incongruent with the results produced. Some novel species relationships are revealed, and a new morphological sectional classification is proposed based on support for these groupings and corresponding morphological characters shared by taxa and their geographical distributions. The putative occurrence of multiple pollination syndromes in this group of taxa, combined with complex biogeographical history of the South-East Asian region, is discussed in the context of these results.(c) 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 173, 549-572.}, language = {en} }
