In 1923, the year C&EN was born, Gilbert N. Lewis of the University of California, Berkeley, published a book titled “Valence and the Structure of Atoms and Molecules.” In the text, Lewis laid out the ...

Targeted cancer drugs work by striking a tight bond between cancer cells and specific molecular targets that are involved in the growth and spread of cancer. Detailed images of such chemical bonding ...

Researchers resolve the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C2, Si2, and their hydrides for the first time ...

"SOMETIMES IT SEEMS to me that a bond between two atoms has become so real, so tangible, so friendly, that I can almost see it. Then I awake with a little shock, for a chemical bond is not a real ...

Because bond order is a chemical concept, and not an observable in the quantum mechanical sense, there does not exist a unique definition of bond multiplicity in quantum chemistry. Thus, it is ...

Framework can investigate regions of chemical space that are normally inaccessible, painting a clearer picture of how molecules can form, transform and interconvert ...

Scientists have produced remarkable images of carbon atoms and the bonds among them. Resembling glowing textbook diagrams, hydrocarbon molecules are shown in high resolution for the first time before ...

Jan. 17 (UPI) --Everything depends on chemical bonds. Without chemical bonds, everything would fall apart. And yet, scientists don't entirely understand how chemical bonding works. Now, for the first ...

Microscopy is advancing in leaps and bounds these days. It was just last week that scientists produced the first image of a hydrogen atom’s orbital structure. Not to be outdone, Berkeley chemists have ...

Yield loss is increasingly driven by molecular variability in thin films, interfaces, and contamination rather than visible defects. Reliability issues often appear first as parametric drift or margin ...
