Tough Ordered Mesoporous Elastomeric Biomaterials Formed at Ambient Conditions

Rajasekharan, Anand K.; Gyllensten, Christoffer; Blomstrand, Edvin; Liebi, Marianne; Andersson, Martin

Synthetic dry elastomers are randomly cross-linked polymeric networks with isotropic and unordered higher-level structural features. However, their growing use as soft-tissue biomaterials has demanded the need for an ordered and anisotropic nano-micro (or) mesoarchitecture, which is crucial for imparting specific properties such as hierarchical toughening, anisotropic mechanics, sustained drug…

Tunable circularly polarized luminescence from molecular assemblies of chiral AIEgens

Song, Fengyan; Cheng, Yanhua; Liu, Qiuming; Qiu, Zijie; Lam, Jacky W. Y.; Lin, Liangbin; Yang, Fafu; Tang, Ben Zhong

Circularly polarized luminescence (CPL) is important to chiral photonic technologies. In molecular systems, besides their intrinsic chemical structures, architectures of molecular assemblies at the mesoscopic scale also account for the final macroscopic CPL properties. Herein, tunable CPL responses can be induced through architectural regulation of these molecular assemblies in suspension…

Collective orientational order and phase behavior of a discotic liquid crystal under nanoscale confinement

Yildirim, Arda; Sentker, Kathrin; Smales, Glen Jacob; Pauw, Brian Richard; Huber, Patrick; Schönhals, Andreas

The phase behavior and molecular ordering of hexakishexyloxy triphenylene (HAT6) DLCs under cylindrical nanoconfinement are studied utilizing differential scanning calorimetry (DSC) and dielectric spectroscopy (DS), where cylindrical nanoconfinement is established through embedding HAT6 into the nanopores of anodic aluminum oxide (AAO) membranes, and a silica membrane with pore diameters ranging…

Liao, Fen; Shi, Ling-Ying; Cheng, Li-Chen; Lee, Sangho; Ran, Rong; Yager, Kevin G.; Ross, Caroline A.

The self-assembly of a high-? silicon-containing side-chain liquid crystalline block copolymer (LC BCP) in bulk and in thin films is reported, and the structural transition process from the hexagonally packed cylinder (HEX) to the body-centered cubic structure (BCC) in thin films was examined by both reciprocal and real space experimental…

Cellular uptake of self-assembled phytantriol-based hexosomes is independent of major endocytic machineries

Rodrigues, Letícia; Schneider, Fabian; Zhang, Xiaohan; Larsson, Elin; Moodie, Lindon W. K.; Dietz, Hendrik; Papadakis, Christine M.; Winter, Gerhard; Lundmark, Richard; Hubert, Madlen

Despite increasing interests in non-lamellar liquid crystalline dispersions, such as hexosomes, for drug delivery, little is known about their interactions with cells and mechanism of cell entry. Here we examine the cellular uptake of hexosomes based on phytantriol and mannide monooleate by HeLa cells using live cell microscopy in comparison…

Encapsulation of Aspartic Protease in Nonlamellar Lipid Liquid Crystalline Phases

Valldeperas, Maria; Talaikis, Martynas; Dhayal, Surender K.; Veli?ka, Martynas; Barauskas, Justas; Niaura, Gediminas; Nylander, Tommy

Encapsulation of proteins within lipid inverse bicontinuous cubic phases (Q2) has been widely studied for many applications, such as protein crystallization or drug delivery of proteins for food and pharmaceutical purposes. However, the use of the lipid sponge (L3) phase for encapsulation of proteins has not yet been well explored.…

Polymorphic states and phase transitions in a comb-like polymer having a rigid polyester backbone and flexible side chains

Danke, Varun; Gupta, Gaurav; Huth, Heiko; Schawe, Jürgen E. K.; Beiner, Mario

Structure formation in an alkoxylated polyester having rigid backbone and flexible side chains composed of 10 alkyl carbons per side chain is studied using X-ray diffraction, conventional DSC and flash DSC techniques. Two crystalline states-modification B and modification A are observed with their occurrence depending on the thermal treatment. Additionally,…

The structure of spray-dried detergent powders

Farshchi, Amin; Hassanpour, Ali; Bayly, Andrew E.

The complex multiscale structure of spray dried detergent granules has been characterized using a complementary range of techniques including scanning electron microscopy (SEM), image analysis, wide angle and small angle X-ray scattering (WAXS, SAXS) and X-ray microtomography. A complex composite structure is revealed due to the multiphase nature of the…

We report a solution-processable π-conjugated molecular building block (denoted as PhDPP) consisting of a rigid and planar core of phenyl-flanked diketopyrrolopyrrole and “soft” branched alkoxy chains that endow the solubility in a variety of organic solvents. Intermolecular hydrogen bonding in PhDPP was revealed in nonpolar solvents above a threshold of…
