Theoretical finishing size limitation and failure mechanism of viscoelastic abrasive media on micro-hole structure
Published 2025-03-01“…Furthermore, based on the pseudo-network structure and elasticity of media, as well as the interaction between continuous matrix with discrete grains, this work theoretically established the mechanics model on single grain and the total material removal model to discussed the variation tendency of material loss volume along with the key parameters (storage modulus, inlet pressure, non-Newtonian index and grain fraction), primarily detecting the theoretical size limitation (around 5 μm). Moreover, further considering the influence of thermal accumulation and grain abrasion on the properties and final effect of media under long finishing duration state, the failure mechanism of abrasive media was investigated and concluded as the deterioration of rheological properties, violent abrasion of grain, and rather low mechanical performance gap between rigid grains with target surface. …”

Fast 3D printing of fine, continuous, and soft fibers via embedded solvent exchange
Published 2025-01-01“…This is achieved via 3D printing by rapid solvent exchange in high yield stress micro granular gel, leading to radial solidification of the extruded polymer filament at a rate of 2.33 μm/s. This process extrudes filaments at 5 mm/s, which is 500,000 times faster than meniscus printing owing to the rapid solidification which prevents capillarity-induced fiber breakage. …”

The beneficial effects of curcumin on aging and age-related diseases: from oxidative stress to antioxidant mechanisms, brain health and apoptosis
Published 2025-01-01“…This agent mediates its effects through several mechanisms, including the reduction of reactive oxygen species (ROS) and oxidative stress-induced damage, as well as the modulation of subcellular signaling pathways such as AMPK, AKT/mTOR, and NF-κB. These pathways are involved in cellular senescence and inflammation, and their modulation can improve cell function and help prevent disease. …”
