Materials can change their shape when hit by a powerful shock wave – a property called plasticity – yet they keep their lattice-like atomic structure. Scientists have now used the X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory to observe, for the first time, how a material’s atomic structure gets deformed when shocked by pressures almost as extreme as the ones at the center of the Earth.
A team of researchers at Stanford have developed a reversible fabric that, without expending energy or effort, maintains skin at a comfortable temperature regardless of the weather.
Researchers have found that an “oxygen sponge”, a catalyst used in vehicle exhaust systems, can also be used as a “hydrogen sponge.”
For the last many years, the commercialization of perovskite photovoltaic cells has gained immense attention. At present, the hot news is that devices developed by using these materials can transform solar energy into electricity with a higher efficiency like never before.
To transform items from science fiction to scientific reality, an in-depth knowledge of the functioning of these unconventional metamaterials is mandatory.
The first ever atomic-scale images of dendrites (i.e. digitated growths), which have the ability to penetrate the barrier in between battery compartments and to trigger fires or short circuits, have been captured by researchers from Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory.
Consider wriggling worms covering a small donut-shaped droplet, where the worms are so tightly packed that they are pressurized to locally line up corresponding to one another.
Rechargeable batteries developed from magnesium, in place of lithium, possess the ability to increase the driving range of the electric vehicle by loading more energy into small-sized batteries. However, unexpected chemical obstacles have decelerated the scientific advancement.
Researchers from EPFL’s Laboratory for Processing of Advanced Composites (LPAC) as well as from the Botanical Garden of the University of Freiburg have investigated how the self-repair nature of the flax plant heals upon being damaged.
For the cuttlefish and octopus, rapidly changing their skin pattern and color to vanish into the environment is simply a part of their camouflage ability. These animals can also quickly and reversibly alter their skin into a textured, 3D surface, giving the animal a raggedy outline that resembles coral, seaweed, or other objects it detects and uses for camouflage.
