Chemists find new dimension to rules for reactions

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.

Step by step toward tomorrow's nanomaterial

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.

Clean 3-way split observed

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.

New light cast on key chemical reactions in interstellar space

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.

Scientists uncover critical step in DNA mutation

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.

When biology gets 'Quirky,' scientists turn to math

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.

Small molecule interactions were central to the origin of life

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.

Emory chemists reveal challenge to reaction theory

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.
