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
Researcher develops cheaper, better LED technology
A Florida State University engineering professor has developed a new highly efficient and low cost light emitting diode that could help spur more widespread adoption of the technology.
3D-printing microscopic fish: Team demonstrates novel method to build robots with complex shapes, functionalities
Nanoengineers at the University of California, San Diego used an innovative 3D printing technology they developed to manufacture multipurpose fish-shaped microrobots—called microfish—that swim around efficiently in liquids, ...
New synthetic tumor environments make cancer research more realistic
Tumors are notoriously difficult to study in their natural habitat – body tissues – but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior.
'Diamonds from the sky' approach turns CO2 into valuable products
Finding a technology to shift carbon dioxide (CO2 ), the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream of many scientists and government officials. ...
Shape-shifting gels get smarter
Gels are useful: we shave, brush our teeth, and fix our hair with them; in the form of soft contact lenses they can even improve our eyesight.
Eliminating entanglements: A new strategy towards ultra-soft yet dry rubbe
Medical implants mimic the softness of human tissue by mixing liquids such oil with long silicone polymers to create a squishy, wet gel. While implants have improved dramatically over the years, there is still a chance of ...
Stretchable, biocompatible hydrogels with complex patterning for tissue engineering
Researchers have developed a new way of making tough—but soft and wet—biocompatible materials, called "hydrogels," into complex and intricately patterned shapes. The process might lead to injectable materials for delivering ...
Solving mysteries of conductivity in polymers
Materials known as conjugated polymers have been seen as very promising candidates for electronics applications, including capacitors, photodiodes, sensors, organic light-emitting diodes, and thermoelectric devices. But they've ...
Breakthrough graphene production could trigger revolution in artificial skin development
A pioneering new technique to produce high-quality, low cost graphene could pave the way for the development of the first truly flexible 'electronic skin', that could be used in robots.
New clot-busting treatment targets number one killer
Australian researchers funded by the National Heart Foundation are a step closer to a safer and more effective way to treat heart attack and stroke via nanotechnology.
