Novel hot-carrier solar cells convert sunlight to electricity more efficiently than conventional solar cells by harnessing charge carriers before they lose their energy to heat. A key to keeping electric charges hot longer is to slow the phonons that transport heat. Recent research shows that thermal transport—and thus performance—in hot-carrier solar cells can be reduced by replacing hydrogen atoms with heavier deuterium atoms.
Columbia University researchers report that they have achieved plasmonically active graphene with record-high charge density without an external gate.

Scientists use beams of electrons to study materials’ properties. Shorter beams produce higher-resolution views. To make shorter beams, the electrons at the tail of the beam need to catch up to the head of the beam. This is accomplished by giving the electrons at the tail extra energy, a so-called “energy chirp.” Scientists have now used a terahertz laser pulse to create this energy chirp.

Not all plastics are created equally – from milk jugs and soda bottles, which are readily recyclable, to multi-layered packaging that increases shelf life and requires less material but is less recyclable – the challenge is for researchers to design a process that allows more of the plastics we use in our everyday lives to end up in our recycle bins rather than the local landfill.
A new platform could accelerate the development of blended materials with desired properties.
The American Association for the Advancement of Science, the world’s largest general scientific society, today announced that 489 of its members, among them eight scientists at Berkeley Lab, have been named Fellows.

How much information can you get from a speck of purple pigment, no bigger than the diameter of a hair, plucked from an Egyptian portrait that’s nearly 2,000 years old? Plenty, according to a new study. Analysis of that speck can teach us about how the pigment was made, what it’s made of – and maybe even a little about the people who made it.
Multilayer plastic materials are ubiquitous in food and medical supply packaging, particularly since layering polymers can give those films specific properties, like heat resistance or oxygen and moisture control. But despite their utility, those ever-present plastics are impossible to recycle using conventional methods.
