6+ hour, 53+ min ago  (242+ words) lead image Microrobots are a compelling technology for biomedical applications from delivering drugs to taking precise diagnostics. But while robots" behavior in Newtonian fluids of constant viscosity is well-studied, the human body contains non-Newtonian fluids that can influence microrobots" movement…...

6+ hour, 43+ min ago  (126+ words) lead image Hohlraums " tiny cavities that convert laser energy into X-rays " are central to inertial confinement fusion, yet their physics are notoriously complex. High-fidelity simulations of hohlraums require huge computational resources to model the interplay of radiation transport, plasma hydrodynamics,…...

3+ week, 4+ day ago  (147+ words) lead image Despite its longstanding ubiquity, fundamental aspects of glass remain mysterious. For example, researchers have struggled to establish a quantitative theory of glass transition that connects energy flow, or thermodynamics, with the dynamic movement of atoms in glass former…...

1+ mon, 2+ day ago  (210+ words) lead image To control gas mixtures with magnets, researchers must exploit the magnetic properties of gas species. However, the effects of magnetic fields on gas transport are not well explored. In particular, few studies have focused on how magnets affect…...
