Noble metal nanostructures have demonstrated a number of intriguing features for both medicine and catalysis. However, accumulation issues have prevented their clinical translation, while their use in catalysis has shown serious efficiency and stability hurdles. Here we introduce a simple and robust synthetic protocol for passion fruit-like nano-architectures composed by a silica shell embeddin...

A fiber’s efficiency in a short-fiber composite can be accurately solved by shear-lag methods, which can account for fiber geometry, an imperfect interface (or interphase), and extend to low volume fractions. Such an analysis was used to evaluate the aspect ratio requirements for singlewalled nanotubes (SWNT) in a polymeric composite and contrast it to conventional fibers. The aspect ratio requ...

LY2157299 (LY), which is very small molecule bringing high cancer diffusion, is a pathway antagonist against TGFβ. LY dosage can be diluted by blood plasma, can be captured by immune system or it might be dissolved during digestion in gastrointestinal tract. The aim of our study is to optimize a "nano-elastic" carrier to avoid acidic pH of gastrointestinal tract, colon alkaline pH, and anti-imm...

Electrical insulation materials are advancing rapidly due to several advantages including light weight, better performance in polluted environment and reduced installation cost. In polymeric micro-composites, enhancing one property of the insulator may affect adversely on the other desired properties. This problem can be addressed practically with the invention of nanocomposites. This article p...

Modern chemical synthesis makes heavy use of different types of catalytic systems: homogeneous, heterogeneous and nano-sized. The latter--nano-sized catalysts--have given rise in the 21st century to a rapidly developing area of research encompassing several prospects and opportunities for new technologies. Catalytic reactions ensure high regio- and stereoselectivity of chemical transformations,...

Two new neutral nano flower polymeric lead(II) coordination compounds, [Pb(tmph)(μ-SCN)₂]n (1) and [Pb(tmph)(μ-NO₃)₂]n (2), [tmph=3,4,7,8-tetramethyl-1,10-phenanthroline], have been synthesized by a sonochemical process and characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. SEM image shows the nano flower morphology f...

Cicada wings consist of nanopillar arrays with a pitch, diameter, and height few hundred nanometers. These show strong antibacterial performance owing to cell membrane damage caused by the physical interaction nanopillars. Polymer-based nanopillars are essential for various industrial applications. Herein, we present fabrication process polymer-based using facile thermal nanoimprint technique. ...
