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.

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.

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.

Recently, I had the opportunity to visit the Energy Department’s National Renewable Energy Laboratory (NREL) for an alumni meeting of the Executive Energy Leadership Academy (Energy Execs), a program that empowers executives to integrate clean energy solutions in their own communities.

Since its inception, more than 200 representatives of industry, government and non-profit organizations have completed the Energy Execs program, delivered through the Executive Energy Leadership Academy. In 2014, I participated in the abbreviated program which offers decision-makers a look at renewable energy and energy efficiency technologies. As part of the experience, we received briefings by NREL technology experts, research laboratory tours and visits to renewable energy installations.

The Electrochemical Society’s Vilas Pol has developed a new process to turn simple packing peanuts into energy-storing battery components.

Pol, an associate professor at Purdue University and active member of ECS, has thoroughly succeeded in turning one person’s trash into another person’s high-tech treasure. He and his team from Purdue University have developed a system that turns the puffy packing peanuts into nanoparticles and microsheets perfect for rechargeable batteries. Pol’s new generation of battery could even outperform the ones we currently use.

We’ve been hearing about the new generation of vehicles for some time now. The self-driving, autonomous, electric car seemed to be so distant that it transformed into a pipe dream—until now. Tesla CEO Elon Musk announced this past week that Tesla’s self-driving cars will hit highways this summer.

On Thursday March 18, Musk arranged a press conference to talk about Tesla’s automobile software update that will eliminate range anxiety—or the fear that your electric car will run out of power before being able to recharge on long trips.

But that wasn’t the highlight of the press conference. Musk casually announced that beginning around June, all Tesla models well get an update that allows them to drive in “Autopilot” mode.

Toyota has just unveiled the prototype of their 3-wheel i-ROAD urban mobility vehicle at the TED Conference in Vancouver.

Those who experienced the vehicle described it as a cross between a zip scooter and an eco-friendly electric car. Toyota is describing this electric two-seater as a “personal mobility vehicle.” The company used the TED Conference as their launching platform for to gauge how the attendees see the future of mobility.

However, the i-ROAD is not designed to be your primary highway-driving vehicle. John Schultz of Toyota Motor Sales USA states that the vehicle would be most effective for every day short trips, such as running errands and grocery shopping.

The research gives scientists clues about the genes that control plant structures and how we can manipulate them to our advantage.

Researchers at the University of Georgia (UGA) are looking to accelerate the biofuel industry with this new development in plant gene structure.

The UGA scientists have discovered that manipulating a certain gene in a hardwood tree makes easier the process of breaking wood into fuel, and simultaneously increases the pace of tree growth.

This from UGA:

In a paper published recently in Biotechnology for Biofuels, the researchers describe how decreasing the expression of a gene called GAUT12.1 leads to a reduction in xylan and pectin, two major components of plant cell walls that make them resistant to the enzymes and chemicals used to extract the fermentable sugars used to create biofuels.
