The gray surface, top, is lanthanum... view more  Credit: CUBE3D Graphic Scientists crafting a nickel-based catalyst used in making hydrogen fuel built it one atomic layer at a time to gain full control over its chemical properties. But the finished material didn't behave as they expected: As one version of the catalyst went about its work, the top-most layer of atoms rearranged to form a new pattern, as if th...

The labs of chemist James Tour and materials theorist Boris Yakobson reported in the American Chemical Society's ACS Nano they have succes...

 E-Mail Photosynthetic organisms tap light for fuel, but sometimes there's too much of a good thing. New research from Washington University in St. Louis reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae -- including key features that both collect energy and block excess light absorption. The study, published Jan. 6 in Science Advances, yields insights relevant to future energy applications. Scientists built a model of the large protein complex called phycobilisome that collects and transmits light energy. Phycobilisomes allow cyanobacteria to t...

Date Time Insights Through Atomic Simulation A recent special issue in The Journal of Chemical Physics highlights Pacific Northwest National Laboratory’s (PNNL) contributions to developing two prominent open-source software packages for computational chemistry used by scientists around the world. PNNL researchers have been instrumental in developing the software packages, called NWChem and CP2K. These programs offer complementary approaches to calculating electronic structure, which is fundamental to atomic behavior and chemical bonding. According to the abstract for this special issue, “...
