Researchers from UCLA’s California NanoSystems Institute (CNSI) have developed a new generation of supercapacitors that not only emphasizes the best inherent properties of the supercapacitor itself, but also combines it with some of the best qualities of batteries to make a new energy storage medium.

The new supercapacitor is paper-thin and has an extremely fast recharge time. Additionally, it can last more than 10,000 recharge cycles.

Researchers believe this new development will yield real-world potential to address energy issues and improve personal electronics.

“The microsupercapacitor is a new evolving configuration, a very small rechargeable power source with a much higher capacity than previous lithium thin-film microbatteries,” said Maher El-Kady, co-author of the study and postdoctoral scholar.

ECS and SEMI are pleased to announce that the annual China Semiconductor Technology International Conference (CSTIC 2015) successfully concluded on March 16th in Shanghai, China with about 311 speakers and 606 attendees from around the world.

This marks the 16th year that CSTIC held this annual international conference. (ECS is a founding sponsor of the event.) With a focus on semiconductor technology and manufacturing, CSTIC promoted technical exchanges on the latest developments in semiconductor technology and manufacturing and facilitated investment and collaboration in the semiconductor industry in Asia, particularly China.

Silicon is the common material used in solar cells and computer chips, but gallium arsenide is an alternative material with many advantages.

When we think of chips and solar cells, we think of silicon. However, silicon isn’t the only chip-making material out there.

Researchers from Stanford University are turning their attention away from silicon and are looking toward gallium arsenide to make faster chips and more efficient solar cells.

Gallium arsenide is a semiconductor material with extraordinary properties. Electrons can travel six times faster in gallium arsenide than in silicon, allowing for faster operation of transistors. Unfortunately, cost effectiveness is not one of gallium arsenide’s alluring properties—which has caused researchers to opt for the much cheaper and less effective silicon material.

One single wafer of gallium arsenide could cost up to $5,000, whereas the same size wafer of silicon costs only $5.

After studying the antibacterial properties of bioplastics, researchers found that albumin looks to be the most promising.

Since Leo Baekeland’s invention of Bakelite in 1907, plastic has undergone a lot of transformation. Now, plastic isn’t just used in toys and phones—it also has promising potential in medical applications.

Researchers from the University of Georgia are creating bioplastics from albumin—a protein found in eggs with significant antibacterial properties—to expand plastic’s potential into areas such as wound healing dressing, sutures, catheter tubes, and drug delivery.

“It was found that it had complete inhibition, as in no bacteria would grow on the plastic once applied,” said Alex Jones, a doctoral student at the University of Georgia. “The bacteria wouldn’t be able to live on it.”

The development detailed in this study is critical due the high percentage of hospital-acquired infections.

The electric car industry is on the rise, but battery performance for these vehicles is still not where it needs to be to implement wide-scale usage. To address this issue, researchers from Dalhousie University have produced a ternary blend of electrolyte additives to improve the performance of the li-ion cell.

An open access paper recently published in the Journal of The Electrochemical Society (JES) details a novel development in electrolyte additives that, once applied to the li-ion cell, demonstrate a very high charge-discharge capacity.

The team began their study by investigating the performance of NMC pouch cells and electrolytes with various sulfur or phosphorus electrolyte additives.

They concluded that the new additive will improve the life cycle performance of the li-ion battery, as well as improve upon its safety.

When it comes to light bulbs, we’ve seen a lot of transformation since Thomas Edison’s practical incandescent bulb. Since then we’ve delved into fluorescent lights, and more recently, LEDs. Now we’re moving on to the next big thing in light bulbs, and that just may be graphene.

The new bulb is projected to last longer and cut energy use by 10 percent.

One small step for renewable energy, and one giant leap for Costa Rica.

Costa Rica has not burned one fossil fuel in over 75 days. The country is currently running completely on renewable energy, primarily due to heavy rains and geothermal energy.

The country is now producing enough electricity though hydropower systems, such as pump storage and run-of-the-river plants, to power the majority of Costa Rica. Pair that with additional geothermal, solar, and wind energy sources and 100 percent renewable energy efficiency is achieved.

Vittorio de Nora Award

Electroless plating is the non-electrical plating of metals to achieve uniform coatings by a process of controlled autocatalytic reduction. We’ve seen a major expansion of electroless plating in plastics, as in the plating of printed electronic circuits. Today, a large number of consumer goods are coated by this method to create durable and attractive surfaces.

Electroless plating was co-discovered in 1944 by Dr. Abner Brenner who was also the first recipient of the ECS Vittorio de Nora Award. The de Nora Award was established in 1971 for contributions to the field of electrochemical engineering and technology. Submit your nominations today.

Dan Fatton, ECS Director of Development & Membership services, spotted an article in My Central Jersey that details a potential game changer in sustainable energy.

Researchers from Rutgers University may have just found the key to advancing renewable resources and potentially growing an energy infrastructure based on sustainability.

The researchers from Rutgers’ Chemistry and Chemical Biology Department have recently developed a novel patent-pending energy storage technology grounded in electrochemical science. The new technology is said to not only be cost-effective, but also a highly efficient way to store sustainable energy for later use.

The research published in the journal Energy & Environmental Science addresses the feasibility of widespread utilization of sustainable power.

“We have developed a compound, Ni5P4 (nickel-5 phosphide-4), that has the potential to replace platinum in two types of electrochemical cells: electrolyzers that make hydrogen by splitting water through hydrogen evolution reaction (HER) powered by electrical energy, and fuel cells that make electricity from combining hydrogen and oxygen,” co-author of the study Charles Dismukes explained to My Central Jersey.
