Published Water for drinking? Nope, water for batteries


A research team develops aqueous rechargeable batteries based on zinc anodes. Polymeric artificial interphase to improve battery stability.
Published New tech solves longstanding challenges for self-healing materials


Engineering researchers have developed a new self-healing composite that allows structures to repair themselves in place, without having to be removed from service. This latest technology resolves two longstanding challenges for self-healing materials, and can significantly extend the lifespan of structural components such as wind-turbine blades and aircraft wings.
Published 2D nanosheets as anodes in Li-ion batteries: The answer is in the sheets


Researchers use titanium diboride nanosheets as anode material in lithium-ion batteries to enable fast charging and extend battery life.
Published Batteries without critical raw materials


The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. Researchers have investigated new combinations of electrolyte solutions and electrode materials for this purpose.
Published Researchers design next-generation electrolytes for lithium metal batteries


A team of researchers has discovered a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries. This new mechanism, which does not depend on the traditional kinetic approach, has potential to greatly enhance the energy density of batteries.
Published Revolutionary technique to generate hydrogen more efficiently from water


Researchers have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas -- an element crucial to many industrial processes. The team found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water is broken down into hydrogen and oxygen. The result is a more energy-efficient method of obtaining hydrogen.
Published One-stop hydrogen shop: Reducing the cost of a future energy carrier


Researchers have demonstrated a proof-of-concept for a novel molecular hydrogen production method that bypasses the need for expensive purification steps. They developed a system where hydrogen is separated and stored in liquid organic hydrogen carriers by catalysis of triaryl boranes in one seamless process. The results of this work will help facilitate the transition to a hydrogen-based economy that is necessary for a more sustainable future.
Published Global collaboration saved countries $67 billion in solar panel production costs


A new study quantifies for the first time the historical and future cost savings to the solar industry from globalized supply chains.
Published Limits of lithium extraction from thermal water


Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility -- the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile. A team of researchers has now summarized the state of the art, analyzed raw materials markets, and assessed technologies.
Published Nano-sized islands open possibilities for application of single-atom catalysts


A new method to anchor single atoms of platinum-group metals on nanometer-sized islands allows for efficiently using these expensive metals as catalysts for a wide variety of applications. Researchers showed that platinum atoms could be confined on small cerium-oxide islands within a porous material to catalyze reactions without sticking to each other, which has been a major stumbling block for their use.
Published Dye-sensitized solar cells achieve a new record


Scientists have increased the power conversion efficiency of dye-sensitized solar cells beyond 15% in direct sunlight and 30% in ambient light conditions.
Published Tandem solar cells with perovskite: Nanostructures help in many ways


By the end of 2021, scientists had presented perovskite silicon tandem solar cells with an efficiency close to 30 percent. This value was a world record for eight months, a long time for this hotly contested field of research. Scientists now describe how they achieved this record value with nanooptical structuring and reflective coatings.
Published Improving light absorption in perovskite/Si tandem solar cells


Engineers have achieved a power conversion efficiency of 23.50% in a perovskite-silicon tandem solar cell built with a special textured anti-reflective coating (ARC) polymeric film.
Published Keeping electricity affordable on wireless charging highways


Efficient pricing will be crucial to minimize energy costs for private operators who provide on-the-highway wireless charging for electric cars -- and for consumers who will use this service, according to new research.
Published Durable, inexpensive catalyst reduces carbon footprint of ammonia production


To reduce the energy requirements of the Haber-Bosch process, which converts nitrogen and hydrogen to ammonia, researchers have developed a metal nitride catalyst containing an active metal (Ni) on a lanthanum nitride support that is stable in presence of moisture. Since the catalyst doesn't contain ruthenium, it presents an inexpensive option for reducing the carbon footprint of ammonia production.
Published Storing hydrogen fuel in salts -- a step toward 'cleaner' energy production


Hydrogen gas could someday replace fossil fuels as a 'clean' energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and converting it to a liquid requires vessels that can withstand extremely high pressures. Now, researchers have developed a method to store and release highly pure hydrogen with salts in the presence of amino acids.
