Selective Modification of Halloysite Nanotubes with 1-Pyrenylboronic Acid: A Novel Fluorescence Probe with Highly Selective and Sensitive Response to Hyperoxide.
A novel fluorescence probe based on modified halloysite nanotubes (HNTs) by using 1-pyrenylboronic acid selectively grafted onto the inner surface of lumen was successfully achieved. The solid-state nuclear magnetic resonance (13C and 11B), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) confirmed that the boronic acid group only binds to alumina at the tube lumen...

231. Disulfide-crosslinked Poly(L-glutamic acid) Grafted Mesoporous Silica Nanoparticles and Their Potential Application in Drug Delivery.
Poly(L-glutamic acid)(PLGA) was grafted onto the surface of
mesoporous silica nanoparticles(MSN) via the ring opening
polymerization of γ-benzyl-L-glutamate N-carboxyanhydride(BLG-NCA) and its subsequent deprotection of benzyl
groups. The PLGA chains were cross-linked with cystamine, and thus forming a
type of redox responsive drug delivery system(MSN-cPLGA). The
structures were characteri...

Bronsted Guanidine Acid-Base Ionic Liquids Novel Reaction Media for the Palladium-Catalyzed Heck Reaction
Br?nsted acid?base ionic liquids (GILs) based on guanidine and acetic acid are efficient reaction media for palladium-catalyzed Heck reactions. They offer the advantages of high activity and reusability. GIL2 plays multiple roles in the reaction: it could act as solvent, as a strong base to facilitate a-hydride elimination, and as a ligand to stabilize activated Pd species.

AMB Express, 2011, 1:34, doi:10.1186/2191-0855-1-34. Superhydrophobic poly(L-lactic acid) surface as potential bacterial colonization substrate
Hydrophobicity is a very important surface property and there is a growing interest in the production and characterization of superhydrophobic surfaces. Accordingly, it was recently shown how to obtain a superhydrophobic surface using a simple and cost-effective method on a polymer named poly(L-lactic acid) (PLLA). To evaluate the ability of such material as a substrate for bacterial colonization,...

Extraction of cellulose nano-crystals from old corrugated container fiber using phosphoric acid and enzymatic hydrolysis followed by sonication
Due to its amazing physicochemical properties and high environmental compatibility, cellulose nano-crystals (CNC) hold great promise for serving as a strategic platform for sustainable development. Now, there has been growing interest in the development of processes using waste or residual biomass as CNC source for addressing economic and environmental concerns. In the present work, a combined pro...

Synthesis of fully alternating polycarbonate with low Tg from carbon dioxide and bio-based fatty acid
The selective copolymerization of CO2 and an epoxide to form fully alternating polycarbonates is a great challenge via catalysis with the zinc–cobalt(III) double metal cyanide complex [Zn–Co(III) DMCC]. We describe the first perfectly alternating copolymerization of CO2 with a bio-based epoxide. The resultant polycarbonate had a low Tgs of 38 to 44 C and two end hydroxyl grou...

Hydrophilic PVA-co-PE nanofiber membrane functionalized with iminodiacetic acid by solid-phase synthesis for heavy metal ions removal
A novel hydrophilic poly(vinyl alcohol-co-ethylene) (PVA-co-PE) nanofiber membrane for heavy metal
ions removal was fabricated by the solid phase synthesis of iminodiacetic acid (IDA) on nanofiber
membrane surfaces. The hydrophilic PVA-co-PE nanofiber membranes were activated with cyanuric chloride.
The IDA was then covalently linked to the activated PVA-co-PE nanofiber membranes. The chemical
str...
