Water in, water out: such is the cycle of porous material. In some cases, like with soils, it is preferable to keep water in. In others, it makes better economic and ecological sense to have porous materials dry faster, e.g. in the paper industries or with plasterboard manufacturing.
Scientists at Brunel University London have perfected the first ever grain refiner master alloy for magnesium-aluminium alloys.
A study conducted by the University of Tennessee (UT) and the Department of Energy’s Oak Ridge National Laboratory (ORNL) could lead to creation of materials for energy-related applications.
A group of researchers from the UK, including academics from Cardiff University, has demonstrated the first practical laser that has been grown directly on a silicon substrate.
A team of physicists from the University of California, San Diego and The University of Manchester is creating tailor-made materials for cutting-edge research and perhaps a new generation of optoelectronic devices. The materials make it easier for the researchers to manipulate excitons, which are pairs of an electron and an electron hole bound to each other by an electrostatic force.
A method to synthesize the first binary compound of oxygen and krypton - a krypton oxide, has been formulated by a team of theoretical chemists at the Institute of Physical Chemistry of the Polish Academy of Sciences. It has been discovered that this unusual substance can be produced even in the existing laboratories using very high pressure.
Perovskite has a hexagonal or rhombohedral structure with formula ABO3, while still belonging to the R3c space group (number #161). They possess ferroelectric, piezoelectric, and superconducting properties and are often used in applications of functional devices.
University of Oregon (UO) researchers have discovered the secret behind the mimicry used by Dracula orchids to attract flies and guarantee their survival, using a 3D printer to spoof the flies.
Gather your patience and put the old “a watched pot never boils” saying to the test. The experience might rival watching paint dry, but of course the water will eventually begin to boil. When it does, you’ll see a flurry of bubbles form and quickly rise to the surface of the water. Once it kicks in, it builds at a furious pace and quickly creates a roiling cauldron on your stovetop. Time to add the pasta.
An active variable stiffness vibration isolator has been developed by researchers from HRL Laboratories’ Sensors and Materials Laboratory. This isolator is capable of millisecond actuation times and 100x stiffness changes, independent of the static load. In the words of Principal Investigator Christopher Churchill, “This performance surpasses existing mechanisms by at least 20 times in either speed or useful stiffness change."
