Prototype sunscreen uses TiO₂ nanoparticles to cool skin while blocking UV rays
Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn't cool people off. However, a new formula, described in Nano Letters, protects against both UV light and heat from the sun using radiative cooling......»»
Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
New strategies enhance stability of metal nanoparticles in green hydrogen production
Efficient and durable low-cost catalysts are essential for green hydrogen production and related chemical fuel production, both vital technologies for the transition to renewable energy. Research in this field increasingly focuses on metal exsolution.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
