In simulations, MIT researchers found that tin telluride’s electron characteristics have a significant impact on their mean free paths. They plotted tin telluride’s range of electron energies against the associated mean free paths, and found the resulting graph looked very …

energyUniversity of Twente boosts efficiency of sunlight conversion of hydrogen fuel using microwires

No Comments
Researchers at the University of Twente’s MESA+ research institute have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using …

physicsUltrasonic Sound tornadoes levitate objects in a soundless void

No Comments
Researchers at the University of Bristol have been able to levitate objects using ultrasonic waves larger than the wavelengths of sound used by the device. This could enable touchless control of drug capsules or micro-surgical implements inside the human body …

cancerBlood test can detect eight cancers in early stages which could save half a million lives every year

No Comments
CancerSEEK is a blood test that detects tiny amounts of DNA and proteins released into the bloodstream from cancer cells. This can then indicate the presence of ovarian, liver, stomach, pancreatic, oesophageal, bowel, lung or breast cancers. Known as a …

DNAElectrically controlled DNA robot arm is 100,000 times faster – millisecond moves enable molecular factories

No Comments
Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast …
