A new device will enable nuclear magnetic resonance spectroscopy, coupled with a powerful molecular sensor, to analyze molecular interactions in viscous solutions and fragile materials such as liquid crystals.
Berkeley Lab scientists have created the first computational model that simulates the light-harvesting activity of thousands of antenna proteins that would interact in the chloroplast of an actual leaf. The results point the way to improving the yields of food and fuel crops, and developing artificial photosynthesis technologies for next generation solar energy systems.
A multi-institutional team of researchers, including scientists from Berkeley Lab, have used a new scanning electron microscopy technique to resolve the unique atomic structure at the surface of a material. This new technique holds promise for the study of catalysis, corrosion and other critical chemical reactions.
Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative to silicon-based devices. Uneven performances, however, have been a persistent problem. That’s now changed.
SWAPPS – Standing Wave Ambient Pressure Photoelectron Spectroscopy – is a new X-ray technique developed at Berkeley Lab’s Advanced Light Source that provides sub-nanometer resolution of every chemical element to be found at heterogeneous interfaces, such as those in batteries, fuel cells and other devices.
