Can different growth recipes lead to the same structural target? Researchers have developed an AI-assisted inverse-design approach that identifies multiple synthesis routes to carbon nanotube arrays with closely matched height, density and alignment. Experiments across three targets demonstrate that similar array structures can emerge from different processing conditions, while individual nanotubes retain microscopic differences. The findings offer greater flexibility for controlled nanomaterial synthesis.

Researchers at Institute of Science Tokyo (Science Tokyo) have developed a new liquid–metal process that can recover freshwater and magnesium resources from the concentrated brine. By combining liquid-tin direct-contact distillation with vacuum degassing, the method removes chlorine- and sulfur-containing species from the tin and enables magnesium-rich precipitates, with MgO as the major crystalline phase, to be recovered during cooling. More than 99% of the magnesium taken up by the liquid tin was recovered.

New research from Pusan National University, South Korea, shows that the direction in which a lightweight AZ31 magnesium alloy plate is struck can strongly affect its ballistic performance. Using high-velocity impact tests, microscopy, crystallographic analysis, and finite-element simulations, researchers traced how crystal texture influences deformation, stress localization, and fracture. The findings could help inform the design of lighter protective structures for weight-sensitive applications.

The human dental pulp stem cell (hDPSC) secretome, enriched in neurotrophic, antioxidant, and immunomodulatory factors, shows strong therapeutic promise. A new study suggests that the hDPSC secretome may support functional recovery after ischemic stroke. In cell and animal models, treatment reduced oxidative stress, neuroinflammation, and neuronal apoptosis while promoting neurogenesis, vascular remodeling, and synaptic recovery. These molecular and structural changes were accompanied by improved motor performance, spatial learning, and memory-related behaviors.
