‘Wearable microgrid’ uses the human body to sustainably power small gadgets
Nanoengineers at the University of California San Diego have developed a “wearable microgrid” that harvests and stores energy from the human body to power small electronics. It consists of three main parts:…
New skills of Graphene: Tunable lattice vibrations
Technological innovation in the last century was mainly based on the control of electrons or photons. Now, in the emerging research field of phononics, phonons or vibrations of the crystal lattice attract…
3D-printing perovskites on graphene makes next-gen X-ray detectors
By using 3D aerosol jet-printing to put perovskites on graphene, scientists at EPFL have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost and health…
Graphene filter makes carbon capture more efficient and cheaper
One of the main culprits of global warming is the vast amount of carbon dioxide pumped out into the atmosphere mostly from burning fossil fuels and the production of steel and cement….
