Berkeley Lab chemists have developed a powerful new method of selectively linking chemicals to proteins, a major advance in the manipulation of biomolecules that could transform the way drugs are developed, proteins are probed, and molecules are tracked and imaged. This technique, called ReACT, is akin to a chemical Swiss army knife for proteins.
Defects and jagged surfaces at the edges of nanosized platinum and gold particles are key hot spots for chemical reactivity, researchers confirmed using a unique infrared probe.
Scientists have enlisted the exotic properties of graphene to function like the film of an incredibly sensitive camera system in visually mapping tiny electric fields. They hope to enlist the new method to image electrical signaling networks in our hearts and brains.
A combination of experiments, including X-ray studies at Berkeley Lab, revealed new details about pesky deposits that can stop chemical reactions vital to fuel production and other processes.
Berkeley Lab chemists have successfully married chemistry and biology to create reactions never before possible. They did this by replacing the iron normally found in the muscle protein myoglobin with iridium, a noble metal not known to be used by living systems.
A new study led by a Berkeley Lab scientist and UC Berkeley professor establishes for the first time copper’s role in fat metabolism, further burnishing the metal’s reputation as an essential nutrient for human physiology.
A team led by Gerbrand Ceder has made a major advance in understanding the chemical processes in “lithium-rich cathodes,” which hold promise for a higher energy lithium-ion battery.
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.
An international collaboration led by Berkeley Lab scientists
has woven the first 3D covalent organic frameworks (COFs) from helical organic threads. The woven COFs display significant advantages in structural flexibility, resiliency and reversibility over previous COFs.
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.
