Discovery of 'slow' electrons in 2D material could lead to new memory device
Over the last decade, researchers have developed two-dimensional materials with fascinating quantum effects that could be harnessed for next-generation technologies.
Discovered Materials is playing AI whack-a-mole to hunt cooler chips
Discovered Materials raised $9 million to fund the hunt for more novel materials to build more efficient chips. O recorte ajuda a contextualizar a pauta dentro de Tech.
New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells
The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal. The study, published in Ele
Scientists just 3D printed one of the hardest metals on Earth
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to m
Researchers unlock high-res view of 2D materials by doing a microscopic twist
By rapidly twisting a microscopically small tip back and forth, researchers at the University of Maryland (UMD) have unlocked a new way to detect subtle changes on the surface of a material flexing in response to infrared light.
Scientists twist crystal layers and reshape matter from within
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up. Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a
Light controls nanoscale 'bubble' domains in a ferroelectric crystal
Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, sensors and future computing technologies.
Boron layers could set a superconductivity record, theoretical study predicts
Scientists in China predict that stacking two microscopic layers of boron could set a new record for superconductivity. Superconductors are materials that conduct electricity with zero resistance. Traditional types need temperatures close to absolute zero to work, requiring compl
A 0.42-nanometer breakthrough could push transistors beyond silicon
Atomically thin semiconductors could enable dramatically smaller and more efficient chips, but a stubborn problem at the boundary between materials has limited their performance. Researchers have now engineered that atomic interface to protect electron flow while still allowing e
Charge-based strategy improves controlled delivery of therapeutic peptides from gelatin-ba
Rice University engineers have developed a new strategy for controlling how therapeutic peptides are released from gelatin-based materials, a step that could make the small but powerful molecules more useful in tissue engineering and drug delivery.

Universidade cria "ouvido biônico" capaz de se conectar ao cérebro humano
Pesquisadores da Universidade de Nankai, na China, desenvolveram um "ouvido biônico" que promete criar uma ligação direta entre um sistema artificial e o sistema nervoso para combater a perda auditiva neurossensorial.
O dispositivo, apresentado na revista científica Nature Materials, funciona como uma interface neuromórfica capaz de reproduzir funções do nervo auditivo. Ao detectar sons, interpreta antes de enviá-los ao c&eacu
