Toward on-board microchip synthesis of CdSe vs. PbSe nanocrystalline quantum dots as a spectral decoy for protecting space assets

Abstract

Quantum dots (QDs) were suggested a decade ago as a means of spectral decoy to divert rocket attacks from flying objects such as satellites but never found industrial applications yet....

Fabrication and catalytic application of a tandem reactor module using Au nanoparticle-coated glass beads as packing materials

“…Generally, there are two dynamical stages in the reduction of 4-NP under the action of NaBH 4 : hydrolysis and hydrogenation. 17,57,58 In hydrolysis, Au NPs with a high coverage and small particle size (27.2 nm) can provide plentiful active sites to accelerate the electron transfer of BH 4 − ions, leading to the generation of abundant activated hydrogen. 54 In hydrogenation, the nitro (-NO 2 ) group is reduced by the activated hydrogen to form the amine (-NH 2 ) group.…”

“…[11][12][13][14][15][16] However, the agglomeration of NPs with strong surface energy often occurs, resulting in deteriorating performance. 17,18 Moreover, the difficult separation and recovery of NPs in the reaction system also hinder their practical applications. 19 In view of these limitations, much attention has been focused on the immobilization of NPs.…”

Microfluidic‐based nanoparticle synthesis and their potential applications

“…This work improves reproducibility and enhances particle growth. The proposed constructive microchip exploits mixing of reactant during reaction which is important to subdue limitations of batch synthesis [89].…”
