Nanoparticle superlattices are periodic arrays of nanoscale inorganic building blocks including metal nanoparticles, quantum dots and magnetic nanoparticles. Such assemblies can exhibit exciting new collective properties different from those of individual nanoparticle or corresponding bulk materials. However, fabrication of nanoparticle superlattices is nontrivial because nanoparticles are noto...

COVER: Colorized, high-resolution transmission electron microscope lattice-fringe image of seven nanoparticles of UO 2 produced by the activity of sulfate-reducing bacteria. Note that the largest uraninite particle is <3 nm in diameter (Suzuki and Banfield, in preparation). Example: Predominantly inorganic nanoparticle formation in acid drainage 3 Other inorganic pathways for formation of nanop...

Ordered gold nanoparticle arrays with high lateral density of 6.87 × 1010 nanoparticles cm−2, which are stable up to temperatures of 600 ◦C, were fabricated. To this end, nanoparticles formed by thermal vacuum evaporation of Au were immobilized within the pores of nanoporous silicon wafers prepared by block copolymer lithography coupled with dry plasma etching. Even after high-temperature treat...

COVER Model of a candidate HIV vaccine prime immunogen (center) engaging germline B cell receptors (bottom) to initiate an antibody immune response. The immunogen is a virus-like nanoparticle, ~30 nanometers in diameter, displaying 60 copies of an HIV gp120 outer domain protein engineered to bind germline precursors of specifi c broadly neutralizing antibodies. This work has promising implicati...

This back cover shows a novel delivery vehicle of RNA nanoparticle (named RIONmiR-143) for RAS-mutated intractable cancers. Tumor-suppressor microRNA-143 (miR-143) silences oncogenic KRAS networks, but it lacks nucleic acid clinical application. research creates the RIONmiR-143 by self-assembly miR-143s and demonstrates functions.

A program package ATSAS 2.1 for small angle X-ray and neutron scattering data analysis is presented. The programs included in the package cover major processing and interpretation steps from primary data reduction to three-dimensional modeling methods. This system is primarily oriented towards the analysis of biological macromolecules, but could also be used for non-biological isotropic and par...

In this critical review we cover the state of art surface deposition complex magnetic molecules. Deposition methods are reviewed, as well most used types surfaces, including use nanoparticle supports. The relevant characterization for molecules on surfaces reviewed along with deposited and their examples. perspectives field close article, reader will get an overview what has been done in acquir...

The Cover Feature illustrates FeCo oxide nanoparticles supported on heteroatom-functionalized multi-walled carbon nanotubes as a bifunctional catalyst for the oxygen reduction and evolution reactions. Nitrogen functionalization of allows controlling nanoparticle dispersion localization, while optimal degree nitrogen doping results in an enhancement electrical conductivity, which together boost ...
