Low-grade waste heat regenerates ammonia battery (12/22/2014)

Low-grade waste heat regenerates ammonia batteryAn efficient method to harvest low-grade waste heat as electricity may be possible using reversible ammonia batteries, according to Penn State engineers. ...> Full Article


Bioplastic -- greener than ever (12/22/2014)

Bioplastic -- greener than everPolylactic acid is a degradable plastic used mostly for packaging. To meet the rising demand, ETH researchers have developed an eco-friendly process to make large amounts of lactic acid from glycerol, a waste by-product in the production of biodiesel. ...> Full Article


Toward a low-cost 'artificial leaf' that produces clean hydrogen fuel (12/21/2014)

For years, scientists have been pursuing 'artificial leaf' technology, a green approach to making hydrogen fuel that copies plants' ability to convert sunlight into a form of energy they can use. Now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production. They describe their nanowire mesh design in the journal ACS Nano. ...> Full Article


Secondary relaxation in metallic glasses: A key to glassy materials and glassy physics (12/21/2014)

Secondary relaxation in metallic glasses: A key to glassy materials and glassy physicsFocusing on metallic glasses as model systems, scientists in China and Germany review the features and mechanisms of the β-relaxations, which are intrinsic and universal to supercooled liquids and glasses. In a new study, they explore many crucial unresolved issues in glassy physics and materials science, including glass transition phenomena and mechanical properties, along with the crystallization and stability of glasses. These scientists also preview the design of new glassy materials with extraordinary properties. ...> Full Article


A better look at the chemistry of interfaces (12/20/2014)

A better look at the chemistry of interfacesSWAPPS -- Standing Wave Ambient Pressure Photoelectron Spectroscopy -- is a new X-ray technique developed at Berkeley Lab's Advanced Light Source that provides sub-nanometer resolution of every chemical element to be found at heterogeneous interfaces, such as those in batteries, fuel cells and other devices. ...> Full Article


VTT developing an environmentally friendly alternative for polystyrene (12/19/2014)

VTT Technical Research Centre of Finland is currently developing an affordable and environmentally friendly alternative for polystyrene from PLA bioplastic, which is derived from organic sources. ...> Full Article


Lengthening the life of high capacity silicon electrodes in rechargeable lithium batteries (12/19/2014)

Lengthening the life of high capacity silicon electrodes in rechargeable lithium batteriesA new study will help researchers create longer-lasting, higher-capacity lithium rechargeable batteries, which are commonly used in consumer electronics. In a study published in the journal ACS Nano, researchers showed how a coating that makes high capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes. ...> Full Article


Chemists fabricate novel rewritable paper (12/18/2014)

Chemists fabricate novel rewritable paperUC Riverside chemists have fabricated novel rewritable paper, one that is based on the color switching property of commercial chemicals called redox dyes. The dye forms the imaging layer of the paper. Printing is achieved by using ultraviolet light to photobleach the dye, except the portions that constitute the text on the paper. The new rewritable paper can be erased and written on more than 20 times with no significant loss in contrast and resolution. ...> Full Article


University of Illinois researchers develop inexpensive hydrolysable polymer (12/18/2014)

University of Illinois researchers develop inexpensive hydrolysable polymerThrough some inventive chemistry, University of Illinois associate professor Jianjun Cheng and his colleagues have developed a class of 'hindered urea bond-containing polymeric materials' or 'poly(hindered urea)s' -- cheap polymers that can be designed to degrade over a specified time period, making them potentially useful in biomedical and agricultural applications. ...> Full Article


Shaping the future of energy storage with conductive clay (12/17/2014)

Shaping the future of energy storage with conductive clayMaterials scientists from Drexel University's College of Engineering invented the clay, which is both highly conductive and can easily be molded into a variety of shapes and sizes. It represents a turn away from the rather complicated and costly processing -- currently used to make materials for lithium-ion batteries and supercapacitors -- and toward one that looks a bit like rolling out cookie dough with results that are even sweeter from an energy storage standpoint. ...> Full Article


New electrolyte for the construction of magnesium-sulfur batteries (12/17/2014)

New electrolyte for the construction of magnesium-sulfur batteriesThe Helmholtz Institute Ulm established by Karlsruhe Institute of Technology is pushing research relating to batteries of the next and next-but-one generations: A research team has now developed an electrolyte that may be used for the construction of magnesium-sulfur battery cells. With magnesium, higher storage densities could be achieved than with lithium. Moreover, magnesium is abundant in nature, it is non-toxic, and does not degrade in air. The new electrolyte is now presented in the journal 'Advanced Energy Materials.' ...> Full Article


Single-atom gold catalysts may offer path to low-cost production of fuel and chemicals (12/16/2014)

New catalysts designed and investigated by Tufts engineering researchers and collaborators have potential to greatly reduce processing costs in future fuels like hydrogen. The catalysts are composed of a unique structure of single gold atoms bound by oxygen to sodium or potassium atoms, supported on non-reactive silica materials. They demonstrate comparable activity and stability with catalysts comprising precious metal nanoparticles on rare earth and other reducible oxide supports when used in producing highly purified hydrogen. ...> Full Article


Heat-conducting plastic developed (12/15/2014)

The spaghetti-like internal structure of most plastics makes it hard for them to cast away heat, but a University of Michigan research team has made a plastic blend that does so 10 times better than its conventional counterparts. ...> Full Article


Process converts human waste into rocket fuel (12/14/2014)

Process converts human waste into rocket fuelBuck Rogers surely couldn't have seen this one coming, but at NASA's request, University of Florida researchers have figured out how to turn human waste -- yes, that kind -- into rocket fuel. ...> Full Article


How can students efficiently get an introduction into materials concepts for solar cells? (12/13/2014)

How can students efficiently get an introduction into materials concepts for solar cells?To date there is mainly basic literature about the physics of solar cells and there are specialized articles and books about certain types or classes of solar cell materials. After introducing the basics of solar cells and materials demands, this textbook brings together the principles of all four classes of materials concepts for solar cells. ...> Full Article
