Fentanyl has killed hundreds of thousands of people globally since 2015. Detection of the drugs during interdiction is currently done through Raman spectroscopy or chemical strips—both of which ...

A chilling risk of recreational nitrous oxide use: Frostbite When compressed gases, including nitrous oxide, expand, they can reach temperatures as low as minus 40 degrees Fahrenheit.

Physicists have discovered that silicon-22 reveals a new proton magic number offering critical insights into nuclear ...

Waveguide structures effectively controlling and guiding terahertz (THz) waves can achieve interesting resonance effects when combined with resonators. At present, achieving high quality factor ...

Nb16W5O55 emerged as a high-rate anode material for Li-ion batteries in 2018 [Griffith et al., Nature2018, 559 (7715), 556–563]. This exciting discovery ignited research in Wadsley–Roth (W–R) ...

Based on the six resonance structures, we performed ab initio VB computations with the BOVB approach. In Figure S1, we showed the BOVB orbitals of structure I for trans -HOON and structure II for ...
