Dimpled particles are synthesized through the seeded polymerization of fluoroacrylate and styrene on swelled polystyrene spheres. The morphologies of the particles can be controlled by the polymerization temperature, the amount of solvent swelling the seeds or the ratio of the fluoroacrylate monomer over styrene. Golf-ball-like particles with many small dimples on their surfaces are obtained at low polymerization temperatures or with a small amount of solvent. Particles with a large single dimple are formed at higher polymerization temperatures, with larger solvent amounts or a higher ratio of fluoroacrylate over styrene. The morphology formation mechanism of these dimpled particles is proposed and the application of these particles in the fabrication of superhydrophobic coatings is demonstrated.

The Effect of Post Heat Treatment on the Microstructure and Mechanical Properties of Cold-Sprayed Zn-6Cu Deposits.

Materials (Basel)

December 2024

Jiangxi Provincial Key Laboratory of Materials Surface Engineering, School of Materials Science and Engineering, Jiujiang University, Jiujiang 332005, China.

To explore the feasibility of preparing Zn alloy bulk, Zn-6Cu deposit was prepared by cold-spraying additive manufacturing. Microstructure, tensile and wear behavior were investigated before and after heat treatment. Cold-sprayed Zn-6Cu deposit was constituted by irregular flattening particles and pores after heat treatment.

Article Synopsis
  • Cellulite (CLT) is a common cosmetic issue for women, characterized by dimpled skin, and is usually treated with invasive methods like liposuction, but safer topical treatments are preferred.
  • This study developed a solid lipid nanoparticle formulation containing caffeine (CA) to enhance its absorption and effectiveness against cellulite, achieving high entrapment efficiency and optimal particle characteristics.
  • The final product, CA-SLN-Ngel, demonstrated significant reductions in subcutaneous fat tissue thickness in histological studies, suggesting it could be an effective non-invasive treatment for cellulite.

Rapid, microwave-assisted deposition of anisotropic silver nanostructures on various substrates.

Department of Atomic and Molecular Physics, Manipal Academy of Higher Education Manipal 576104 Karnataka India

A facile, rapid, and scalable microwave-assisted solvothermal technique (MAST) has been developed to deposit anisotropic silver nanoparticles (AgNP) on various substrates in a solution medium. SEM-EDS and XRD were used to characterize the morphology and structure of the deposits. Deposition on non-patterned aluminium led to near-spherical AgNP agglomerates all across the surface.

During atmospheric pressure plasma impingement, plasma induced liquid flow will influence the transport and distribution of plasma generated charged and reactive species in liquids. We use particle image velocimetry and supplementary pH, conductivity and temperature measurements to investigate electrical properties of an AC kHz plasma jet interacting with water and electrolytes. We observe that the dominant driving mechanism in low conductive solutions are surface forces such as shear stresses and stagnation-pressure induced dimpling.

Pure copper is very soft, however, hardening the pure copper with most strengthening mechanisms leads to a significant reduction in electrical conductivity. Grain refinement is a better strengthening mechanism to maintain high enough electrical conductivity. Plastic deformation at room temperature followed by post-annealing is one of the best methods to achieve fine-grained metals and alloys.
