The Electrochemical Society’s Jim Edgar has developed a new process to build better semiconductors, which will vastly improve the efficiency of electronic devices and help propel the semiconductor industry.

Edgar, a Kansas State university distinguished professor of chemical engineering and an active member of ECS since 1981, has just received a patent for his “Off-axis silicon carbide substrates” process, which is a way to build a better semiconductor. This new process could mean big things for the electronics and semiconductor manufacturing industries.

“It’s like a stacked cake separated by layers of icing,” Edgar said. “When the layers of semiconductors don’t match up very well, it introduces defects. Any time there is a defect, it degrades the efficiency of the device.”

Water splitting into hydrogen on a metal wire and oxygen on the catalyst.

New research out of Yale University, led by Ph.D. student Staff Sheehan, recently unveiled a new catalyst to aid in the generation of renewable fuels.

Sheehan’s main area of research has been water splitting. In his recently published paper, he takes the theories and processes involved in water splitting and uses a specific iridium species as a water oxidation catalyst. This has led to new breakthroughs in artificial photosynthesis to develop renewable fuels.

“Artificial photosynthesis has been widely researched,” Sheehan says, “but water oxidation is the bottleneck—it’s usually the most difficult reaction to perform in generating fuel from sunlight.”

Researchers from Rice University have developed a novel theory that combines strength, stiffness and toughness of composites into a single design map. The dimensionless computer-drawn maps can be applied to anything from nanoscale to buildings.

“That’s the beauty of this approach: It can scale to something very large or very small,” said Rouzbeh Shahsavari, an assistant professor of civil and environmental engineering and of materials science and engineering.

The development could help lead to safe, efficient artificial photosynthetic systems that replicate the natural process of photosynthesis that plants use to convert sunlight, water, and carbon dioxide into oxygen and fuel in the form of carbohydrates, or sugars.

The Electrochemical Society’s Nate Lewis is leading some pioneering research at Caltech with the vision of efficient, affordable, and effective renewable energy sources.

Dr. Lewis, an active member of ECS since 1982, has designed a novel electrically conductive film – which has the potential to result in the development of devices that can harness sunlight to change water into hydrogen fuel.

(Take a look at his plenary lecture on sustainable energy technology he gave at a past ECS meeting.)

“We’ve discovered a material which is chemically compatible with the semiconductor it’s trying to protect, impermeable to water, electrically conductive, highly transparent to incoming light, and highly catalytic for the reaction to make oxygen and fuels,” said Dr. Lewis.

He and his team have developed a process that allows the solar-driven production of fuel to be performed with record efficiency, stability, and effectiveness.

If you’re not excited about the promising potential of solar yet, you’re about to be.

According to a new report by GTM Research and the Solar Energy Industries Association (SEIA), solar is growing faster than all other sources of energy in the United States.

In the report U.S. Solar Market Insight 2014 Year in Review, GTM and SEIA were able to establish that solar is continuing its upward trend in the U.S. with an increase of 30 percent more photovoltaic installations than in 2013.

Not convinced yet? The analysts also paired solar against also forms of energy in their report. When compared to other non-renewable energy sources such as coal and natural gas, it showed equally impressive results.

Rodney Borup of the Los Alamos National Laboratory will be awarded the 2015 Energy Technology Division Research Award for his pioneering work in energy conversion and storage, specifically related to sustainability and fuel cells.

The prestigious award was established in 1992 to encourage excellence in energy related research.

Dr. Borup is widely recognized for his work in fuel cell transportation with such corporate and academic organizations such as General Motors and Los Alamos National Laboratory (LANL). He joined LANL in 1994 as a post-doctoral researcher, where he would eventually move on to become the Program Manager for the Fuel Cells and Vehicle Technologies Program and Team Leader for Fuel Cells Program —titles which he currently holds.

The tire can generate energy from friction and heat. However, Goodyear has yet to describe the materials to be used.

There’s no question that engineers and manufacturers around the world are moving away from the fuel-based car to the electric vehicle. In order to make these cars possible, they must improve in efficiency. Now, one company is looking outside the box for the answer to electric car sustainability.

Goodyear has just announced the concept of their new tire, which will harvest heat in a variety of ways to help power electric vehicles. The new BH-03 tire is poised to be able to absorb heat while static due to the ultra-black texture of the tire, as well as take advantage of the natural occurrence of friction as the tire moves.

The integration of silk into the lithium-ion battery allowed the battery to work for over 10,000 cycles with only a nine percent loss in stability.

The words “lithium-ion” and “battery” have become almost synonymous recently. While the li-ion battery is used in a multitude of applications, it still does not have a long life without a recharge.

Now, researchers have developed an environmentally friendly way to boost the performance of the li-ion battery by focusing on a material derived from silk.

In the li-ion battery, carbon is the key component for storage. In most situations, graphite takes that role – but it has limited energy capacity. In order to improve the performance of the li-ion battery, researchers looked to replace graphite with a material developed using a sustainable source.

Blood clots treated with PolySTAT (second from right) had denser fibrin networks, which helps reinforce and strengthen the clots.

University of Washington researchers have developed a new injectable polymer that could keep soldiers and trauma patients from bleeding to death, called the PolySTAT.

The new polymer works to strengthen blood clots once administered into the patient’s bloodstream in a simple shot. The polymer then finds unseen internal injuries and starts working to stop the bleeding.

Researchers believe this could become the first line of defense for anything from battlefield injuries to car accidents. With testing already underway, the polymer has the potential to reach humans in as few as five years.
