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
Better thermal-imaging lens from waste sulfur
Sulfur left over from refining fossil fuels can be transformed into cheap, lightweight, plastic lenses for infrared devices, including night-vision goggles, a University of Arizona-led international team has found.
Using light to identify chiral molecules for pharmaceuticals
(Phys.org) —A combination of nanotechnology and a unique twisting property of light could lead to new methods for ensuring the purity and safety of pharmaceuticals.
Preventing build-up of toxic fouling films on medical devices
A 'one-step' coating that blocks protein growth and kills surface-bound bacteria on silicone may significantly reduce infections from medical devices such as catheters, finds a study led by A*STAR Institute of Bioengineering ...
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 3D tissue ...
Stronger, better solar cells: Graphene research on the cusp of new energy capabilities
(Phys.org) —There remains a lot to learn on the frontiers of solar power research, particularly when it comes to new advanced materials which could change how we harness energy.
Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
Vine-tree-like CNT architectures
The vine-tree structure is widely observed in nature when the plant has a growth habit of trailing or climbing stems. The vines use trees for growth rather than devoting energy to development of supportive tissue, enabling ...
Sperm-bots are made to move in desired direction (w/ Video)
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.
