Berkeley Lab researchers report the first experimental observation of ultrafast charge transfer in photo-excited MX2 materials, the graphene-like two-dimensional semiconductors. Charge transfer time clocked in at under 50 femtoseconds, comparable to the fastest times recorded for organic photovoltaics.
Researchers have, for the first time, characterized so-called quantum vortices that swirl within tiny droplets of liquid helium. The research, led by scientists at Berkeley Lab, UCLA, and SLAC, confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new avenues for studying quantum rotation.
Eight national laboratories, including Berkeley Lab, are combining forces with the National Center for Atmospheric Research and other institutions in a project called Accelerated Climate Modeling for Energy, or ACME, designed to accelerate the development of state-of-the-science Earth system models for scientific and energy applications.
In partnership with Save the Bay, Berkeley Lab volunteers helped to transplant over 2,200 baccharis glutinosa seedlings along the Martin Luther King, Jr. Regional Shoreline Park in Oakland recently. This native perennial plant supports the local marsh ecosystem and creates habitat for wetland animals and insects.
Berkeley Lab researchers have recorded the first direct observations of how facets form and develop on platinum nanocubes in solution, pointing the way towards more sophisticated and effective nanocrystal design and revealing that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.
The Dark Energy Survey kicked off its second season, snapping shots of deep space with its 570-megapixel camera mounted on the Victor M. Blanco Telescope in Chile. Berkeley Lab designed and fabricated all 62 of the CCDs in the camera, which will be used over the survey’s five-year mission to investigate dark energy and its impact of our universe.
A project begun some 13 years ago by Berkeley Lab’s Jay Keasling was culminated with an announcement from the partnership of Sanofi, the multinational pharmaceutical company, and PATH, the nonprofit global health organization, that 1.7 million treatments of semi-synthetic artemisinin have been shipped to malaria-endemic countries in Africa.
The severe pollution common in much of India offers an opportunity to better understand air pollution’s causes and effects. A Berkeley Lab researcher is employing unique approaches to studying India’s air pollution in an effort to develop global strategies for combating it.
Eight Bay Area high school students are participating in this summer’s iCLEM program, earning money and gaining “college knowledge” while conducting bioenergy research in the state-of-the-art scientific laboratories of the Joint BioEnergy Institute (JBEI). iCLEM stands for Introductory College Level Experience in Microbiology.
