Atomically thin electronics built using chemical reactions

Enlarge (credit: Getty images) There have been a variety of demonstrations of the capabilities that atomically thin materials can bring to electronics—extremely small size, excellent performance, and some distinctive properties. But almost all of these demonstrations required that the electronics being tested were essentially assembled by hand. Materials like graphene are often placed on a […]

Heat-driven photovoltaic device hits 40 percent efficiency

Enlarge (credit: Getty Images | Aurich Lawson) As installing renewable generating sources continues to set annual records, we’re reaching the point where storing the power they generate becomes essential. Proper storage can provide a way to cover temporary drops in production due to changing weather and can potentially offer a way to use power at […]

Take a peek inside a flickering candle flame with these 3D-printed shapes

New research from MIT explores fire from a whole series of new perspectives. The research uses deep-learning approaches that extract the vibrational features of flames as flickering objects and, in turn, renders them into sounds and materials. The 19th-century physicist Michael Faraday was known not only for his seminal experimental contributions to electromagnetism but also […]

Hydrogen-soaked crystal lets neural networks expand to match a problem

Enlarge (credit: Getty Images ) Training AIs remains very processor-intensive, in part because traditional processing architectures are poor matches for the sorts of neural networks that are widely used. This has led to the development of what has been termed neuromorphic computing hardware, which attempts to model the behavior of biological neurons in hardware. But […]
