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
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.
Soft elastomeric structures easy to fabricate using 'click-e-bricks'
New material could be used for energy storage
(Phys.org) —Lawrence Livermore researchers have made a material that is 10 times stronger and stiffer than traditional aerogels of the same density.
New material structures bend like microscopic hair
MIT engineers have fabricated a new elastic material coated with microscopic, hairlike structures that tilt in response to a magnetic field. Depending on the field's orientation, the microhairs can tilt to form a path through ...
Big beats bolster solar cell efficiency
(Phys.org) —Playing pop and rock music improves the performance of solar cells, according to new research from scientists at Queen Mary University of London and Imperial College London.
Nano-cone textures generate extremely 'robust' water-repellent surfaces
When it comes to designing extremely water-repellent surfaces, shape and size matter. That's the finding of a group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory, who investigated the effects ...
Neutron tomography technique reveals phase fractions of crystalline materials in 3-dimensions
The method overcomes limitations of existing techniques which are limited to the surface or small-sized specimens, and allows a 3-D representation of the phase fractions within the sample volume. The work has just been published ...
New microfluidic approach for the directed assembly of functional materials
(Phys.org) —Researchers from the University of Illinois at Urbana-Champaign have developed a new approach with applications in materials development for energy capture and storage and for optoelectronic materials.
Researchers build 3-D structures out of liquid metal
(Phys.org) —Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.
Breakthrough in flexible electronics enabled by inorganic-based laser lift-off
Flexible electronics have been touted as the next generation in electronics in various areas, ranging from consumer electronics to bio-integrated medical devices. In spite of their merits, insufficient performance of organic ...
