Prebiotic phosphorylation enabled by microdroplets [PDF]

Proceedings of the National Academy of Sciences, 2017
The significant acceleration of reactions in confined environments has recently been reported in the literature (1⇓⇓⇓⇓⇓–7). The reaction environments investigated span a diverse range, including charged microdroplets (1⇓–3), microdiameter emulsions (5), inverted micelles (8), and the surfaces of aerosol particles (9).

Chromium Salt: A Review of Salt Formation, Hygroscopic Properties, and Impact on 316 L Corrosion in Hydrochloric Acid

Materials and Corrosion, EarlyView.
This article examines the impact of externally introduced chromium compounds on the localized corrosion of 316 L stainless steel in acidic chloride environments such as hydrochloric acid. While the corrosion resistance of 316 L relies on the formation of a chromium‐rich passive oxide layer, industrial conditions may expose the steel to various chromium

The Air–Water Interface as the Reaction Site in Microdroplets: A Case Study of Thiol Oxidation

ChemistryEurope
The air–water interface plays a crucial role in microdroplet reactions. In this study, we investigated the oxidation of two thiol molecules on water microdroplets: 2‐mercaptosuccinic acid (MSH) and 3‐phenyl‐2‐sulfanylpropanoic acid (PSH), with PSH being ...

Fabrication of 512-Channel Geometrical Passive Breakup Device for High-Throughput Microdroplet Production

Micromachines, 2019
We present a 512-microchannel geometrical passive breakup device for the mass production of microdroplets. The mass production is achieved through the passive breakup of a droplet into two droplets.

Review on Processing Control Strategy for Electrochemical Additive Manufacturing

MetalMat, EarlyView.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

Polymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.

Crystalline Poly(L‐Lactic Acid) Nanoparticles via Nonsolvent‐Induced Cascade Phase Separation

Journal of Polymer Science, EarlyView.
Water is used as the nonsolvent to induce liquid/liquid phase separation (LLPS) of poly(L‐lactic acid) (PLLA)/propylene carbonate solution and PLLA crystallization. Due to the two levels of cascade LLPS coupled with confined PLLA crystallization, three types of polymeric nanoparticles, including PLLA single crystals, Ouzo crystalsomes, and sheaf‐like ...

Bouncing microdroplets on hydrophobic surfaces

Proceedings of the National Academy of Sciences
Intuitively, slow droplets stick to a surface and faster droplets splash or bounce. However, recent work suggests that on nonwetting surfaces, whether microdroplets stick or bounce depends only on their size and fluid properties, but not on the incoming velocity.

Ambient, Bias‐Free, Green Nanoparticle Synthesis via Microdroplet‐Confined Galvanic Chemistry

Small, EarlyView.
Confined galvanic reactions within sprayed microdroplets drive the direct growth of metal nanoparticles on conductive surfaces under ambient conditions. Eliminating the need for external bias and thermal input, this approach offers a simple route toward more sustainable nanoparticle synthesis.

Charged Microdroplets Deposition for Nanostructured-Based Electrode Surface Modification

Surfaces
Accelerated synthesis of gold nanoparticles (AuNPs) in charged microdroplets produced by electrospray ionization (ESI) was exploited to modify the surface of graphite screen-printed electrodes (GSPEs).
