A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening the door to atom-specific analysis and control.

Precisely measuring the exact time that an electron spends inside a quantum tunneling barrier during strong-field ionization has so far proved challenging.

Quantum materials exhibit remarkable emergent properties when they are excited by external sources. Functional applications of these properties rely heavily on their tunability in real time ...

The company ultimately trademarked Roy’s white powder, called polytetrafluoroethylene (PTFE), as Teflon in 1944. Teflon had unique properties that made it particularly appealing to the U.S. military: ...

An argon dielectric barrier discharge (DBD) atmospheric-pressure plasma jet (APPJ) is designed and employed for surface modification of polytetrafluoroethylene (PTFE). The plasma diagnostics and ...

High-pressure pump–probe experiments reveal the mechanism of excited-state proton-coupled electron transfer and a shift from stepwise to concerted pathways.

Thermo Fisher Scientific Inc., the world leader in serving science, introduced a groundbreaking transmission electron microscope to a packed room of a ...

In the study “ Engineering an organic electron-rich surface passivation layer for efficient and stable perovskite solar cells,” published in Cell Reports Physical Science, the scientists ...

The Environmental Protection Agency (EPA) is proposing to remove polytetrafluoroethylene (CAS No. 9002-84-0) from the current list of inert ingredients approved for use in food use and nonfood use ...

Magnesium complex plucks fluorine from polytetrafluoroethylene, then gives it away The unprecedented room-temperature experiment is a proof-of-concept for turning Teflon waste into a source of ...
