Advancements in Biosensors Based on the Assembles of Small Organic Molecules and Peptides.

Over the past few decades, molecular self-assembly has witnessed tremendous progress in a variety of biosensing and biomedical applications. In particular, self-assembled nanostructures of small organic molecules and peptides with intriguing characteristics (e.g.

Expanding the "Magic Triangle" of Reinforced Rubber Using a Supramolecular Filler Strategy.

A strategy for optimizing the rolling resistance, wet skid and cut resistance of reinforced rubber simultaneously using a supramolecular filler is demonstrated. A β-alanine trimer-grafted Styrene Butadiene Rubber (A-SBR) pristine polymer was designed and mechanically mixed with commercially available styrene butadiene rubber to help the dispersion of a β-alanine trimer (A) supramolecular filler in the rubber matrix. To increase the miscibility of A-SBR with other rubber components during mechanical mixing, the pristine polymer was saturated with ethanol before mixing.

Anomalously Shaped Functional Particles Prepared by Thiol-Isocyanate Off-Stoichiometric Click Dispersion Polymerization.

Anomalously shaped microparticles have attractive advantages in applications. They are usually prepared by chain-growth polymerizations in heterogeneous systems. Recently, thiol-X step-growth polymerizations have been used to produce functional particles with a regular shape but rarely anomalous shapes.

Synthesis of graphene by chemical vapor deposition: effect of growth conditions.

Graphene has attracted a great deal of attention due to its extraordinary physical and chemical properties. But the control of growth of high-quality, large-area and inexpensive graphene is still the bottleneck for practical applications. Chemical vapor deposition (CVD) has become the most common method for graphene growth due to its high production and large area of product.

Preparation of polymeric Janus particles by directional UV-induced reactions.

Polymeric Janus particles are obtained by UV-induced selective surface grafting polymerizations and coupling reactions, in virtue of the light-absorption of photoreactive materials such as the immobilized photoinitiator and spread photoinitiator solution on the surfaces exposed to UV light and the sheltering of densely arrayed immovable particles from light. Varying the monomers or macromolecules applied in photografting polymerization or coupling reaction, and choosing diverse polymeric particles of various size, bicolor and amphiphilic Janus particles could be successfully achieved. Observations by fluorescence microscope, scanning electron microscope ,and transmission electron microscope confirmed the asymmetrical morphology of the resultant Janus particles.
