Scientists make germanium superconducting for the first time
Researchers have achieved superconductivity in germanium, a common semiconductor, by precisely doping it with gallium atoms. This breakthrough, detailed in a new study, could enable more efficient quantum devices and cryogenic electronics. The material conducts electricity with zero resistance at 3.5 Kelvin.
Scientists uncover hidden cavities in 2D materials
Researchers have discovered that stacks of two-dimensional materials naturally form microscopic cavities that trap light and electrons, altering quantum behavior without the need for mirrors. This finding, observed using a novel terahertz spectroscope, could enable new ways to control exotic quantum states. The study was published in Nature Physics.
Scientists develop LED therapy to kill cancer cells safely
Researchers from the University of Texas at Austin and the University of Porto have created a cancer treatment using LED light and tin nanoflakes that destroys up to 92% of skin cancer cells without harming healthy tissue. This affordable alternative to traditional therapies relies on near-infrared photothermal principles. The breakthrough, published in ACS Nano, aims to make targeted cancer care more accessible worldwide.
