A simple and reproducible water-in-oil (W/O) nanoemulsion technique for making ultrasmall (<15 nm), monodispersed and water-dispersible nanoparticles (NPs) from chitosan (CS) is reported. The nano-sized (50 nm) water pools of the W/O nanoemulsion serve as "nano-containers and nano-reactors". The entrapped polymer chains of CS inside these "nano-reactors" are covalently cross-linked with the cha...

Aims: Newly developed drug-eluting stents (DES) aim to promote early endothelialisation and prevent stent thrombosis. We sought to evaluate the extent of neointima growth by optical coherence tomography (OCT) three months after implantation of a polymer-free stent with a nano-sized-pore surface eluting sirolimus. Methods and results: In this prospective, multicentre, open-label study, patients ...

Nanoheterostructures combining Prussian blue (PB) or analogues (PBA) coordination polymers with other inorganic materials onto a single nanosystem are highly challenging and rapidly emerging class of discrete hybrid multifunctional nano-objects, where chemical physical properties can act separately in synergy. They present various morphologies compositions, including diverse combinations nanosi...

The synthesis of nano-sized particles of NU-1000 (length from 75 nm to 1200 nm) and PCN-222/MOF-545 (length from 350 nm to 900 nm) is reported. The catalytic hydrolysis of methyl paraoxon was investigated as a function of NU-1000 crystallite size and a significant enhancement in the rate was observed for the nano-sized crystals compared to microcrystals.

this experiment was conducted in order to evaluate the effects of foliar application of ordinary and nano-particles of zinc oxide on the response of corn to salinity. treatments included two corn genotypes (seed mass and sc 704), three spray levels (zinc oxide, nano-sized zinc oxide, and a spray of water treatment) and three salinity levels (0, 75 and 150 mm nacl). shoot dry matter was decrease...

1. General Introduction Conductive polymer composite materials deserve interest in several application fields [1]. A composite consisting of conductive fillers and an insulating polymer becomes electrically conductive as the filler content exceeds a certain critical value, which is generally attributed to percolation phenomenon. These percolation threshold values for the particular polymer comp...
