Thioflavin T (ThT) is a molecular-rotor-type fluorophore reputed for the selective binding to amyloid fibrils. Using induced circular dichroism, here we show that ThT binds in an orderly manner to α-helical poly-L-glutamic acid (PLGA) implying that neither stacked β-sheets nor π-π stacking interactions are necessary for the binding between the dye and proteins.

Bis(imino)phenoxide complexes of zirconium possess spectacular reactivity towards the solvent-free polymerization of cyclic ester monomers and lactides. Polymerization of lactide is living and the resulting product has exceptionally high number average molecular weights (Mn). Polymerization of β-butyrolactone gives syndiotactic poly(3-hydroxybutyrate) with good Mn and molecular weight distribut...

In this work, a comparison between two different preparation methods for the improvement of dissolution rate of an antifungal agent is presented. Poly(ε-caprolactone) (PCL) electrospun fibers and β-cyclodextrin (β-CD) complexes, which were produced via an electrospinning process and an inclusion complexation method, respectively, were addressed for the treatment of fungal infections. Voriconazo...

An ethoxy-bridged dinuclear indium catalyst was used for the ring opening polymerization of the cyclic ester β-butyrolactone to form the biodegradable polyester poly(hydroxybutyrate) (PHB). The catalyst shows remarkable activity and control during polymerization, allowing for formation of diblock polymers. Addition of high ratios of alcohols to the catalyst leads to fast chain transfer and immo...

The synthesis of photoluminescent conjugated polymer silica ionogels using sol-gel chemistry is described. Cooperative self-assembly of an ionic liquid, the silica precursor and poly(9,9-dioctylfluorene) (PFO) via hydrogen bonding and π-stacking interactions drives formation of the PFO β-phase.

We present the genome of Salinisphaera shabanensis, isolated from a brine-seawater interface and representing a new order within the Gammaproteobacteria. Its adaptations to physicochemical and nutrient availability fluctuations include six genes encoding heavy metal-translocating P-type ATPases and multiple genes involved in iron uptake, siderophore production, and poly-β-hydroxybutyrate synthe...

Poly(methylhydrosiloxane) (PMHS) supported organic catalysts promoted the Diels-Alder reaction of dienes with α,β-unsaturated aldehydes, also in pure water, in yields and enantiomeric excesses comparable to those observed with the non-supported catalysts (up to 93% ee). Recycling of the catalysts was performed with no loss of enantioselectivity for at least five reaction cycles.

Amphiphilic star-block copolymers based on poly(3-hydroxybutyrate) with adamantyl end-functionalization were synthesized via anionic ring-opening polymerization and alkyne-azide "Click Chemistry" coupling. In aqueous medium, the copolymers self-assembled into nanogel-like large compound micelles, and transformed into vesicular nanostructures under the direction of host-guest interaction between...

Oceanimonas sp. GK1 (IBRC-M 10197) is a marine halotolerant gammaproteobacterium which was characterized as producing large amounts of poly-β-hydroxybutyrate. Here we present the whole-genome sequence of Oceanimonas sp. GK1, which consists of a single circular chromosome of 3,514,537 bp and two plasmids 8,462 and 4,245 bp in length.

Poly(ethylene oxide) (PEO) and Li6.75La3Zr1.75Ta0.25O12 (LLZTO)-based composite polymer electrolytes (CPEs) are considered one of the most promising solid electrolyte systems. However, agglomeration LLZTO within PEO lack Li+ channels result in poor electrochemical properties. Herein, a functional supramolecular combination (CD-TFSI) consisting active β-cyclodextrin (CD) with self-assembled LiTF...
