Directional freeze-casting method produces highly structured metal foams by ice-templating

Posted on March 31, 2016 by rberkowitz

The key to producing an anisotropic tungsten metal foam is starting with a non-metallic oxide powder, and reducing it to metal before densifying the final structure. Continue reading →

Fluorescent Colloidal Nanomaterial Rapidly Internalized into Living Cells

Posted on January 26, 2016 by rberkowitz

Researchers have successfully incorporated colloidal nanoplatelets, a disc-like variation on spherical quantum dots, in a biological system. The new “lipoprotein nanoplatelets” were found to be rapidly internalized into living cells while retaining their fluorescence, making them uniquely valuable in live-cell imaging and labelling.

Some Like it Hot: Simulating Single Particle Excitations

Posted on December 17, 2015 by rberkowitz

Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Now, for the first time, the interplay between the plasmon mode and the single particle excitation within a small metal cluster has been simulated directly. Read more at Berkeley Lab…my last embargo-held press release written while full-time at LBNL, despite the byline! Continue reading →
