What is greedflation and is it driving higher prices

Is inflation being aided and abetted by price-gouging? The idea of exploiting inflation to create excessive profits has become known as greedflation—a concept that is...

Scientists find new way to make cheaper batteries

New, easily fabricated, high performance carbon microlattice electrodes could soon be used to make cheaper batteries powered by readily available sodium ions. The approach was...

Why perovskites could take solar cells to new heights

Perovskites hold promise for creating solar panels that could be easily deposited onto most surfaces, including flexible and textured ones. These materials would also be...

These energy-packed batteries work well in extreme cold and heat

Engineers at the University of California San Diego have developed lithium-ion batteries that perform well at freezing cold and scorching hot temperatures, while packing...

New optical device could help solar arrays focus light, even under clouds

Researchers imagined, designed, and tested an elegant lens device that can efficiently gather light from all angles and concentrate it at a fixed output...

Scientists find way to reduce electric vehicle battery testing time by 75%

Testing the longevity of new electric vehicle battery designs could be four times faster with a streamlined approach, researchers at the University of Michigan...

New model provides solutions for better, safer lithium-metal batteries

A new study by Stanford University researchers lights a path forward for building better, safer lithium-metal batteries. Close cousins of the rechargeable lithium-ion cells widely...

Scientists develop first perovskite solar cell that could last for over 30 years

Princeton Engineering researchers have developed the first perovskite solar cell with a commercially viable lifetime, marking a major milestone for an emerging class of...

Scientists find way to make lithium-ion batteries last longer in extreme cold

When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion batteries’ anodes...

Scientists invented an entirely new way to make solar cells

Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn’t be flexible enough to bend...
