A modeling framework for the complete evaporation of particle-laden droplets, including touchdown events where the air-liquid interface approaches the substrate, is presented. The inclusion of particle jamming into the model, creating a transition from free advection to an immobile porous plug, is essential to making realistic predictions for the deposit's dimensions. By removing the need to track jammed particle fronts explicitly, as often considered, we are able to run simulations until solute has jammed everywhere in the drop. This allows for valid comparisons with experimental findings on the dried deposit's topography. Our model can also be easily applied to general contact line geometries, allowing us to explore the influence of contact line curvature on the local deposit profile.

Photoaging is common and represents one of the primary pathways for hair damage in daily life. Hydrolyzed keratin, which is usually derived from wool and consists of a series of polypeptide molecules, has been investigated as a UV damage prevention ingredient for hair care. Scanning Electron Microscopy (SEM) and fluorescent penetration experiments verified that hydrolyzed keratin can deposit on the hair cuticles to form a film and partly penetrate into the hair cortex.

Clarifying the stability and co-transport of environmental colloids and radionuclides in porous media is crucial, as they pose potential risks to nuclear environmental safety. However, there is limited knowledge of the significant role of protein corona in Eu(III) transport carried by bentonite colloids (BC) in the presence of bovine serum albumin (BSA). The protein corona mediated the stability and co-transport behaviors of BC and Eu(III) in saturated quartz columns were investigated, and a ripening adsorption co-transport model (RACM) was established to qualitatively describe the Eu(III) transport by composited colloids.

The development of efficient and low-cost photocatalysts has always been sought in H production from water cracking. Herein, a series of MoB/MnCdS composites were developed for high-performance photocatalytic H production. MnCdS nanoparticles were deposited on bulk metalloid MoB via a hydrothermal method (as confirmed by morphology tests) to construct a Schottky heterojunction.

Optical synaptic devices (OSDs) have neuromorphic vision sensing capability showing great potential in breaking the von Neumann bottleneck and facilitating future artificial vision systems. However, the applications of two-dimensional (2D) material-based OSDs are still impeded by complicated structures, preparation techniques and so on. In this work, we propose a 2D OSD based on BiSe films prepared by a chemical vapor deposition method followed by an in-situ thermal treatment.

Gold nanorods (GNRs) are valued for their tunable surface plasmon resonance (SPR) and unique optical properties, but precise control over their size and shape remains challenging. Current synthesis techniques often yield polydisperse samples and require high concentrations of cytotoxic surfactants, limiting their biomedical applications. In this study, we introduce a novel electrochemical synthesis method that offers precise control of GNR characteristics by leveraging open circuit potential (OCP) data from colloidal synthesis.
