New Cancer Treatments Come in Nano-Sized Packages

Brain tumors are protected by the brain-blood barrier — a series of defenses that protect the brain from toxic molecules, but also keep out cancer drugs that could kill the cancerous cells. To help cancer drugs access the tumor, the Lab’s Ting Xu is making tiny nanocarriers that protect the drugs during their journey to the tumor. More>

Thermoelectrics: An Old, New Technology

About two-thirds of all energy produced is lost as heat. If thermoelectrics could recover five-percent of that, it could save millions of dollars. Alphabet Energy is producing the most efficient thermoelectric devices ever made for waste-heat recovery, using abundant, cheap and scalable materials. The company was co-founded in 2009 by Lab materials scientist Peidong Yang. More>

Lanzara Profiled in Moore Foundation’s ‘Beyond the Lab’

Materials scientist Alessandra Lanzara is a Moore Foundation grantee working on a cutting-edge technique called angle-resolved photoemission spectroscopy, or ARPES. This experimental tool gives scientists a glimpse into the secret lives of electrons and atoms, and could one day allow us to alter their properties using just a flash of light. More>

A Leap Toward a ‘Perfect’ Quantum Metamaterial

Scientists have devised a way to build a “quantum metamaterial” – an engineered material with exotic properties not found in nature – using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors. More>

Atomic Force Microscope Reveals Chemical Ghosts

To the surprise of chemists, a new technique for taking snapshots of molecules with atomic precision is turning up chemicals they shouldn’t be able to see. Researchers took snapshots of two molecules reacting on the surface of a catalyst, and found intermediate structures lasting for the 20 minutes or so it takes to snap a photo. More>
