  • Chemical bonding | College of Chemistry
    Zinc-zinc bonds are rare in chemistry So are linear four-metal compounds Nevertheless, Trevor D Lohrey, a member of John Arnold’s group at the University of California, Berkeley, has made the first molecule with a Re-Zn-Zn-Re core Lohrey used a rhenium(I) salt to reduce ZnCl2 and make a zinc cation to which anionic rhenium compounds
  • What happens when you explode a chemical bond?
    Chemical bonds Ultraviolet light shatters the links between atoms in the DNA of our skin cells, potentially causing cancer UV light also breaks oxygen bonds, eventually creating ozone, and cleaves hydrogen off other molecules to leave behind free radicals that can damage tissue
  • Turning chemical bonds inside out | College of Chemistry
    However, C–C single bonds, especially when they are unstrained, remain relatively inert The Berkeley team is reporting a new method that cleaves C–C bonds in nitrogen-containing rings Using an excess of a silver salt and a common fluorinating reagent, the reaction unfurls the ring to a linear alkyl chain with a fluorine atom at one end
  • Catalyst breaks only molecules’ toughest C–H bonds
    The catalyst’s selectivity is particularly apparent in dehydroabietic acid, says Hartwig The compound that has multiple aromatic and benzylic C–H bonds as well as aliphatic secondary and tertiary C–H bonds But the catalyst only goes after a single methyl hydrogen transforming it into a boron group, albeit in moderate yield
  • Meet our faculty: Martin Head-Gordon | College of Chemistry
    To better understand how and why bonds form, he also works on energy decomposition analysis (EDA), which gives the value of physically different contributions to chemical bonds Head-Gordon’s Inaugural Article presents an advance in EDA for understanding chemical bonds by properly including spin-coupling effects
  • MOFs COFs | College of Chemistry
    Invented by UC Berkeley's Professor Omar Yaghi, COFs and MOFs consist of molecules (organics for COFs and metal-organics for MOFs) that are stitched into large and extended netlike frameworks whose structures are held together by strong chemical bonds Such frameworks show great promise for, among other applications, carbon sequestration
  • Liquid Sunlight: The Evolution of Photosynthetic Biohybrids
    Under solar irradiation, the integrated biohybrids could effectively capture sunlight and reduce CO 2 into a common chemical intermediate, acetic acid, without additional external energy input, and the energy conversion efficiency could be as high as 3 6% This solar-to-chemical energy conversion efficiency can be further optimized by tuning
  • Red light-powered device for CO₂ fixation | College of Chemistry
    Because sunlight isn’t always available, his team is identifying ways to store renewable energy into chemical bonds One idea is to use sunlight to create chemical fuels that can be stored and used later This process, known as photoelectrochemical CO₂ reduction, could help us store energy and reduce carbon emissions
  • Cracking the code to soot formation | College of Chemistry
    Soot particles are formed when gaseous molecules are heated to high temperatures, and they don't easily turn back to gaseous molecules the way water droplets do when they are heated up Strong chemical bonds hold soot particles together "Making soot is more like baking a cake than it is like condensing water
