magnetic field effects on the elastic response of polymeric piezoelectric cylinder reinforced with carbon nanotubes (cnts) is studied. the cylinder is subjected to internal pressure, a constant electric potential difference at the inner and outer surfaces, thermal and magnetic fields. the mori-tanaka model is used for obtaining the equivalent material properties of the cylinder. based on the ch...

Background:Chitosan and Calcium are one of the natural polymeric materials obtained from the exoskeleton of Xylotrupes gideon through demineralization, deproteinization and deacetylation processes. Nano chitosan and calcium can inhibit the demineralization process, which is caused by the consumption of acetic acid. This study aims to determine the effect of nano chitosan pretreatment and ...

Microfabrication of dissolvable, swellable, and biodegradable polymeric microneedle arrays (MNs) were extensively investigated based in a nano sensitive fabrication style known as micromilling that is then combined with conventional micromolding technique. The aim of this study was to describe the polymer selection, and optimize formulation compounding parameters for various polymeric MNs. Inve...

In the current issue of ACS Nano, Löbling, Haataja et al. craft polymeric nanoparticles with a hierarchy of nontrivial surface structures by combining conventional interpolyelectrolyte complexation with steric control from an uncharged copolymer block. Remarkable cylindrical and lamellar nanodomains are produced on the polyionic coronae of spherical micelles. Here, we discuss generalizing this ...

The interest in micro- and nano-devices based on biodegradable polymers for in vivo applications is growing rapidly and the key to these applications lies in the fashioning of features analogous to the size of cells. This paper presents fabrication techniques for leveraging micro- and nanostructures on biodegradable polymers. Innovative approaches such as replication molding, laser interference...

Biocatalysis is increasingly being explored for the sustainable development of green industry. Though enzymes show great industrial potential with their high efficiency, specificity, and selectivity, they suffer from poor usability stability under abiological conditions. To solve these problems, researchers have fabricated nano- micro-sized biocatalytic reactors based on self-assembly various p...

Single-chain polymeric nanoparticles are artificial folded soft nano-objects of ultra-small size which have recently gained prominence in nanoscience and nanotechnology due to their exceptional and sometimes unique properties. This review focuses on the current state of the investigations of click chemistry techniques for highly-efficient single-chain nanoparticle construction. Additionally, re...
