|A University of California, Riverside researcher is leading a team that won a nearly $500,000 grant to study a process that transforms harmful greenhouse gas emissions into valuable fuels and chemicals by using a unique catalyst. ...> Full Article|
One strategy for addressing the world's energy crisis is to stop wasting so much energy when producing and using it, such as in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat. Now Northwestern University scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. This outstanding property could be exploited in solid-state thermoelectric devices, with potentially enormous energy savings.

|Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have created a 3-D vascular system that allows for high-performance composite materials such as fiberglass to heal autonomously, and repeatedly. ...> Full Article|
|Engineers at the University of California, San Diego, have created new ceramic materials that could be used to store hydrogen safely and efficiently.
The researchers have created for the first time compounds made from mixtures of calcium hexaboride, strontium and barium hexaboride. They also have demonstrated that the compounds could be manufactured using a simple, low-cost manufacturing method known as combustion synthesis. ...> Full Article|
|Shape-memory polymers are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of translation of the concept to approved products is extremely low. In 2014 (4) special issue of Science China Chemistry, a paper described the general usefulness as well as the limitations of the shape-memory polymers for biomedical applications. ...> Full Article|
Scratches in the car finish or cracks in polymer material: Self-healing materials can repair themselves by restoring their initial molecular structure after the damage. Scientists of the Karlsruhe Institute of Technology and Evonik Industries have developed a chemical crosslinking reaction that ensures good short-term healing properties of the material under mild heating. The research results have now been published in the Advanced Materials journal.

|Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material. ...> Full Article|
|Stanford scientists have created a copper-based catalyst that produces large quantities of ethanol from carbon monoxide gas at room temperature. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists. ...> Full Article|
|A fundamental chemical discovery should allow tress to soon play a major role in making high-tech energy storage devices. A method has been discovered to turn cellulose -- the most abundant organic polymer on Earth and a key component of trees -- into the building blocks for supercapacitors. ...> Full Article|
|New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology. ...> Full Article|
|Chemists in Syracuse University's College of Arts and Sciences have, for the first time, created enzyme-like activity using peptides that are only seven amino acids long. ...> Full Article|
|Drexel University researchers are turning some of the basic tenets of chemistry and physics upside down to cut a trail toward the discovery of a new set of materials. They're called 'polar metals' and, according to many of the scientific principles that govern the behavior of atoms, they probably shouldn't exist. ...> Full Article|
|A new approach to studying solar panel absorber materials has been developed by researchers in France, Acta Cryst. (2014). B70, 390. The technique could accelerate the development of non-toxic and readily available alternatives to current absorbers in thin film based solar cells. ...> Full Article|
New field of 'strain engineering' could open up areas of materials research with many potential applications.
