Recent Progress on Graphitic Carbon Nitride–Based Photocatalysts for Hydrogen Peroxide Synthesis

Exploration, EarlyView.
This review summarizes recent progress in using graphitic carbon nitride (g‐C3N4) photocatalysts to produce hydrogen peroxide (H2O2). It highlights how solar energy can cleanly convert water and oxygen into this valuable chemical. We discuss key modification strategies, such as defect engineering, doping, and junction construction, to enhance ...

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

Food Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic

Architecting nano‐Al/HMX/CuO energetic micro‐units unlocks superior interface and highly efficient combustion

InfoMat, EarlyView.
Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,

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).

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing

Laser &Photonics Reviews, EarlyView.
Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

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

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 ...

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.

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 ...
