Researchers at Ruhr-University Bochum discovered how tiny gold particles selectively transform methanol into formaldehyde, a crucial step in producing everyday plastics. The catalyst produces only water as a byproduct, making it an environmentally friendly alternative.
Researchers confirm experimentally that quantum effects allow chemical reactions to proceed rapidly, even at low energies. By merging beams of particles, they achieved a collision temperature of just 0.01 K and observed dramatic changes in reaction rates, revealing the power of quantum phenomena in cold chemistry.
A team of researchers at Ames Laboratory has solved a century-old debate over the Fenton reaction, determining that it depends on pH levels. The discovery opens up possibilities for new uses of the reaction in wastewater treatment and industrial oxidations.
Theoretical chemists at Emory University have solved an important mystery about the rates of chemical reactions and the Polanyi rules. They found that a pre-reactive long-range force can align the reaction of a chlorine atom with methane, inhibiting the reaction. The research has implications for the development of cleaner fuels.
Empa researchers have successfully fabricated small fragments of graphene, known as nanographenes, using a surface chemical route. The reaction pathway consists of six steps with five intermediate products, which can be stabilized on semiconductor surfaces, enabling the fabrication of tailored nanographenes.
Researchers developed a new method to model hydrogen molecule-surface interactions, enabling accurate predictions of chemical reactions. The technique offers 'chemical precision' in calculating reaction barriers and energy changes.
Researchers at the University of Southern California have observed a clean three-way split in a molecule for the first time. The study uses a sym-triazine molecule and energizes its electrons to create identical and equally energetic parts.
Scientists have developed a detailed understanding of neutral-neutral reactions at low temperatures, shedding light on their importance in interstellar chemistry. The study's findings suggest that these reactions can play a significant role in the chemistry of interstellar space, contrary to conventional wisdom.
Researchers have gained insights into a critical reaction that transforms guanine base into 8-oxo-guanine, leading to cancer development. The reaction involves sodium ions promoting bonding between water molecules and the guanine base.
Ohio State University researchers used mathematical simulations to study chemical reactions in cells, finding that many graphs indicate quirky behavior. This 'quirkiness' may be essential for biology and could help explain why cells sometimes react unexpectedly to medicines.
Shapiro's theory suggests that small molecule interactions were central to the origin of life, rather than self-replication. He introduces the concept of a 'driver' reaction linked to a free energy source to convert an unorganized mixture into a self-regulated metabolic network.
Researchers at Emory University reveal a new pathway for formaldehyde decomposition that bypasses the traditional transition state, providing evidence for alternative mechanisms in chemical reactions. The study's findings have implications for our understanding of transition-state theory and its applications in chemistry and biochemistry.
Ruedenberg's theories describe how molecules' energy states change during reactions, predicting product properties. His contributions help elucidate bond formation between atoms.
Researchers at Stanford University study hydrogen atom collision with deuterium molecule, finding product travels in opposite direction than expected. The results suggest a more complex process involving multiple reaction mechanisms.
Researchers at Stanford University and the University of Durham report a surprising observation in a hydrogen-exchange reaction, where a tiny proportion of H2 molecules is flying off in an unexpected direction. This finding suggests more than one mechanism by which H and D2 come together and react.
