New Spectroscopic Technique Could Accelerate the Push for Better Batteries

Method developed at Berkeley Lab’s Advanced Light Source measures electronic changes in a working battery electrode

A new technique developed at Berkeley Lab’s Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications.

The technique, which uses soft X-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode. (more…)

UCLA researchers capture wasted heat, use it to power devices


Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine.

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have taken an important step toward harnessing that heat and converting it for practical use. The advance could lead to more energy-efficient appliances and information processing devices. (more…)

Broker Fees from Mutual Funds Affect Advice; Predict Worse Performance, New Study Says

TORONTO, ON – Brokers are supposed to recommend investments that are in the best interests of their clients.

But a study published in the February 2013 issue of the Journal of Finance has found that mutual funds offering higher broker fees attract the most investments, especially when the broker is not affiliated with the mutual fund company. Every additional dollar paid to a broker corresponds with another six dollars invested into the fund, and another fourteen dollars if the broker is an unaffiliated third party whose compensation depends exclusively on sales commissions.
