Ligand-engineered copper nanoclusters could help combat CO2 emissions
Dec 13, 2024 (Nanowerk News) While the humble copper (Cu) may not boast the allure of gold or silver, its remarkable versatility makes it invaluable in cutting-edge research. A collaborative effort by scientists from Tohoku University, the Tokyo University of Science, and the University of Adelaide has unveiled a groundbreaking...
Body-heat powered wearable devices closer to reality
Dec 12, 2024 (Nanowerk News) A QUT-led research team has developed an ultra-thin, flexible film that could power next-generation wearable devices using body heat, eliminating the need for batteries. This technology could also be used to cool electronic chips, helping smartphones and computers run more efficiently. Professor Zhi-Gang Chen, whose...
Bringing the power of tabletop precision lasers for quantum science to the chip scale
Dec 12, 2024 (Nanowerk News) For experiments that require ultra-precise measurements and control over atoms — think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates — lasers are the technology of choice, the more spectrally pure (emitting a single color/frequency), the better. Conventional lab-scale laser technology currently achieves this...
Superflares once per century
Dec 12, 2024 (Nanowerk News) There is no question that the Sun is a temperamental star, as alone this year’s unusually strong solar storms prove. Some of them led to remarkable auroras even at low latitudes. But can our star become even more furious? Evidence of the most violent solar...
Hydrogel robots for targeted drug delivery
Dec 11, 2024 (Nanowerk News) In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoid or even bio-mimicking robots; think instead of tiny bubble-like spheres. Such robots would have a long and challenging list of...
Researchers discover new third class of magnetism that could transform digital devices
Dec 12, 2024 (Nanowerk News) A new class of magnetism called altermagnetism has been imaged for the first time in a new study. The findings could lead to the development of new magnetic memory devices with the potential to increase operation speeds of up to a thousand times. Altermagnetism is...
Novel MOF materials with almost perfect water repellency
Dec 12, 2024 (Nanowerk News) Scientists from Karlsruhe Institute of Technology (KIT) and the Indian Institute of Technology Guwahati (IITG) have developed a surface material that repels water droplets almost completely. Using an entirely innovative process, they changed metal-organic frameworks (MOFs) – artificially designed materials with novel properties – by...
reversible sliding motion in ammonium-linked ferrocene
Dec 12, 2024 (Nanowerk News) Artificial molecular machines, nanoscale machines consisting of a few molecules, offer the potential to transform fields involving catalysts, molecular electronics, medicines, and quantum materials. These machines operate by converting external stimuli, like electrical signals, into mechanical motion at the molecular level. Ferrocene, a special drum-shaped...
