Caltech scientists have developed a novel 3D printing method called HIAM that allows precise control over the shape and composition of metal alloys, enabling the creation of materials with enhanced mechanical properties and microstructures, such as stronger copper-nickel alloys with potential applications in biocompatible devices and space components.
Caltech scientists have developed a novel 3D printing technique called hydrogel-infusion additive manufacturing (HIAM) that allows precise control over the shape and composition of metallic alloys, enabling the creation of stronger, more resilient materials with customizable properties, such as copper-nickel alloys, by fine-tuning their microstructure and composition.
A comprehensive analysis of previous research has found significant differences in the brain's white matter between regular cannabis users and non-users. The study, which reviewed 30 studies involving 2,898 participants, revealed that cannabis users generally showed lower integrity in the superior longitudinal fasciculus, a key nerve bundle associated with executive functions, and higher mean diffusivity in the corpus callosum, which connects the brain's two hemispheres. These changes were more pronounced in those who started using cannabis at a younger age and for longer periods. However, the research also highlighted the need for more standardized methods of measuring cannabis use and longitudinal studies to better understand the impact of cannabis on the brain's white matter.
Researchers have studied the microstructure and crystal order during the freezing of supercooled water drops. They used optical imaging and X-ray scattering data to analyze the process. The study provides insights into the rates of ice nucleation and the formation of different ice structures. The data and codes used in the study are available for further research.
