Flow-controlled synthesis of gold nanoparticles in a biphasic system with inline liquid–liquid separation

Abstract

4-Dimethylaminopyridine-stabilised gold nanoparticles are synthesised in a biphasic flow reactor system using organic/aqueous membrane separators and gas-permeable tubing.

New Approaches to Produce Large‐Area Single Crystal Thin Films

“…In the wet chemical synthesis of nanostructured materials, directing a crystal facet by using a ligand or by selective etching of other facets has been widely investigated for preparing metal nanosheets and nanowires. [98,99] Very recently, Park et al has demonstrated a 9 nm-thick continuous Au (111) thin film by adopting the selective etching and the facet-directing ligand. [41] They converted a thermally-evaporated polycrystalline Au thin film to a single crystal Au (111) thin film.…”

Aggregation emission of AuNCs induced by chitosan self-assembled multilayers and sensitive sensing for water content in ethanol

“…Aggregation-induced emission (AIE) materials usually show the high luminous intensity and good bleaching resistance in the aggregate and solid states. [1][2][3] With the AIE material, we not only solve the problem of quenching induced by aggregation of traditional uorescent substances but also improve the contrast before and aer the aggregation-enhanced uorescence, which is very advantageous for improving the sensitivity of uorescence sensing and the quality of uorescence imaging. 4,5 In view of the above advantages, the development and application of uorescent materials with AIE characteristics have never stopped, and remarkable achievements have been made in uorescence sensing, biological imaging, drug delivery and release, medical diagnosis, and treatment.…”

Graphene Quantum Dots with Improved Fluorescence Activity via Machine Learning: Implications for Fluorescence Monitoring

“…Furthermore, varied autonomous synthesis technologies have been developed to synthesize nanomaterials. For instance, gold nanoparticles − and metal halide perovskite quantum dots − have been reported to use batch and flow reactor technologies. These technologies are suitable for high-throughput chemical reactions, which can accelerate the synthesis process, decrease the experiment cost, and help investigate the synthesis mechanism.…”
