New perovskite technology combines light sensing and visual memory in an integrated device, emulating aspects of human vision to enable advanced artificial intelligence.
Scientists have developed 'multielement ink' - the first high-entropy semiconductor that can be processed at low-temperature or room temperature. Multielement ink could enable cost-effective and energy-efficient semiconductor manufacturing.
The behavior of electrons in liquids determines a vast range of chemical processes and thus essential processes in organisms and the world as a whole. But electron movements are extremely hard to capture because they take place within attoseconds: the realm of quintillionths of a second.
Researchers use microscopic, 3D printed mushroom-like structures to achieve unprecedented control over the speed, path, and patterning of bouncing water droplets. This new surface offers advances in self-cleaning, water harvesting, and green energy technologies.
Material used in organic solar cells can also be used as light sensors in electronics. This is shown by researchers who have developed a type of sensor able to detect circularly polarised red light. Their study paves the way for more reliable self-driving vehicles and other uses where night vision is important.
Embedding antioxidant nanoparticles that mimic enzymes into colored contact lenses creates an eye shield that protected against cell damage and inflammation in animal studies, presenting a new way to prevent vision-threatening eye diseases.
