A new development out of Caltech could be the first step to producing commercially feasible graphene-based solar cells and LEDs, large-panel displays, and flexible electronics.

“With this new technique, we can grow large sheets of electronic-grade graphene in much less time and at much lower temperatures,” says Caltech staff scientist David Boyd, who developed the method.

While the amazing potential of graphene is universally accepted among the scientific community, scientists have struggled with achieving the properties of the material on an industrially relevant level. The existing techniques either require temperatures that are too hot, or have intrinsic flaws such as deformation of the materials that compromise strength properties.

Edgar’s new patented process will allow for the building of better semiconductors.

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.”

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.

Synthesizing the material as a thin film instead of as a bulk powder opens up new possibilities for fuel cell technology.

Researchers from Cornell University have developed a way to synthesize a new thin-film catalyst to improve efficiency and effectiveness in fuel cells.

For the first time ever, researchers were able to explain the epitaxial thin-film growth of a fundamental electrode component of the fuel cell, which could result in a more effective cathode.

“Up to now, research on oxygen catalysts in thin film form for clean-energy applications has been focused on the perovskite-structured oxides and their structural derivatives,” said lead researcher Araceli Gutierrez-Llorente. “The much less studied cubic pyrochlore structure is an appealing alternative to perovskites for such applications as fuel cell cathodes.”

Researchers, social scientists, and advocates are constantly examining the issue of the global lack of adequate sanitation in hopes to find an economic and sustainable solution. From Britain’s poo-powered bio-bus to the Gates Foundation’s effort to turn waste into drinking water – you can see the innovative answers popping up almost everywhere.

ECS has also joined the fight with our first Science for Solving Society’s Problems Challenge by awarding $210,000 of seed funding to innovative research projects addressing critical technology gaps in water and sanitation.

Now, researchers out of the University of West England are turning the focus from poop to pee with their new development in what they have termed urine-tricity.
