Unleashing perovskites' potential for solar cells

Researchers have been able to decipher a key aspect of the behavior of perovskites made with different formulations: With certain additives there is a kind of "sweet spot" where greater amounts will enhance performance and beyond which further amounts begin to degrade it.

Sodium ion battery research could power up renewable energy storage

Longer life and increased capacity for a new technology battery that could be the workhorse of a renewable energy grid are the goals of a study of the effect of charging cycles on the structure of anodes in sodium ion batteries.
28 Jan

Nanoscale drug delivery method developed

Researchers have developed a novel way to deliver drugs and therapies into cells at the nanoscale without causing toxic effects that have stymied other such efforts. The work could someday lead to more effective therapies and diagnostics for cancer and other illnesses.

Breaking barriers in solar energy

Stop for a moment and imagine an efficient highway system. No need to jockey for position, no choke-point merging from three lanes into one, no long idles at ill-timed traffic lights, no rolling roadblocks as the motorist ahead of you prepares for a turn that is still five miles away. Regardless of the number of cars, you would know what smooth sailing looks and feels like. That's the life solid-state researchers want for electrons as they work to capture the sun's extraordinary energy and convert it into electricity.

3D printed sponge to minimise effects of cancer treatment

With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.

Potential for floating photovoltaic systems

Researchers estimate that installing floating solar photovoltaics on the more than 24,000 man-made U.S. reservoirs could generate about 10 percent of the nation's annual electricity production. Their findings reveal for the first time the potential for floating PV to produce electricity in the United States.

$2 million DOE grant for pumped heat electricity storage

Southwest Research Institute has received a $2 million grant from the United States Department of Energy's Advanced Research Projects Agency-Energy to develop an advanced pumped heat electricity storage (PHES) system. This system offers twice the energy density of a lithium ion battery and is based on an innovative thermodynamic cycle to store energy in hot and cold fluids.
