Materials science is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many universities. It is also an important part of forensic engineering and failure analysis. Materials science also deals with fundamental properties and characteristics of materials. The material of choice of a given era is often a defining point. Phrases such as Stone Age, Bronze Age, and Steel Age are good examples. Originally deriving from the manufacture of ceramics and its putative derivative metallurgy, materials science is one of the oldest forms of engineering and applied science. Modern materials science evolved directly from metallurgy, which itself evolved from mining and (likely) ceramics and the use of fire. A major breakthrough in the understanding of materials occurred in the late 19th
Pumping iron: A hydrogel actuator with mussel tone
(Phys.org) —Protein from a small, tasty mollusk inspired Michigan Technological University's Bruce P. Lee to invent a new type of hydrogel actuator.
First step towards 'programmable materials'
Researchers from Empa and ETH Zurich have succeeded in producing a prototype of a vibration-damping material that could change the world of mechanics forever. The material of the future is not only able to ...
New shrinking gel steers tooth tissue formation
A bit of pressure from a new shrinking, sponge-like gel is all it takes to turn transplanted unspecialized cells into cells that lay down minerals and begin to form teeth.
Fully compostable bioplastic made from shrimp shells
(Phys.org) —Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects—from cell phones to food containers and toys—using a fully degradable ...
Novel laser produces random mid-infrared light for improved imaging applications
Most lasers produce coherent light, meaning that the light waves are perfectly synchronized with each other. Spatially coherent waves, however, can interfere with one another and produce speckles in an image. ...
Optical nanocavity to boost light absorption in semiconductors
Associated with unhappy visits to the dentist, "cavity" means something else in the branch of physics known as optics.
An essential step toward printing living tissues
A new bioprinting method developed at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard School of Engineering and Applied Sciences (SEAS) creates intricately patterned ...
Researcher bringing 3-D TV back from the dead
One UCF researcher may be on the brink of bringing 3-D- TV back from the dead.
In situ bandgap tuning of graphene oxide achieved by electrochemical bias
The ability to modulate the physical properties of graphene oxide within electronic components could have numerous applications in technology, WPI-MANA scientists report
Spider silk ties scientists up in knots
Two years ago, researchers from Iowa State University (USA) published a study which concluded that spider silk conducts heat as well as metals. Now, a team from the University of the Basque Country (Spain) ...
Pushing back against drug-resistant bugs
Some pathogens can adapt to the presence of drugs that would normally be lethal, and such antibiotic-resistant microbes are now the scourge of hospitals worldwide. Discovering new antibiotics is a laborious ...
Sperm-bots are made to move in desired direction (w/ Video)
Harnessing randomness to improve lasers
Randomly arranged items usually have poor optical properties. The rough—or random—surface of a frosted-glass window, for example, obscures the view of an object. The optical industry therefore expends ...
Researchers find simple, cheap way to increase solar cell efficiency
Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification ...
Researchers make powerful new microscale torsional muscle/motor from vanadium dioxide (w/ Video)
Vanadium dioxide is poised to join the pantheon of superstars in the materials world. Already prized for its extraordinary ability to change size, shape and physical identity, vanadium dioxide can now add ...
