Freezing lithium batteries may make them safer and bendable

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing ...

New method increases energy density in lithium batteries

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method to increase the energy density of lithium (Li-ion) batteries. He has built a trilayer structure that ...

Researchers use acoustic voxels to embed sound with data

Columbia Engineering researchers, working with colleagues at Disney Research and MIT, have developed a new method to control sound waves, using a computational approach to inversely design acoustic filters that can fit within ...

Team advances single molecule electronic DNA sequencing

Researchers from Columbia University, with colleagues at Genia Technologies (Roche), Harvard University and the National Institute of Standards and Technology (NIST) report achieving real-time single molecule electronic DNA ...

Location data on two apps enough to identify someone, says study

Stripping a big data set of names and personal details is no guarantee of privacy. Previous research has shown that individual shoppers, Netflix subscribers and even taxicab riders are identifiable in heaps of supposedly ...

Heat and light get larger at the nanoscale

In a new study recently published in Nature Nanotechnology, researchers from Columbia Engineering, Cornell, and Stanford have demonstrated heat transfer can be made 100 times stronger than has been predicted, simply by bringing ...
