We present a path-integral Monte Carlo procedure for the calculation of the second molecular virial coefficient accounting for intramolecular flexibility. This...
Measurement and computation are fundamental tools in science. However, many of our ordinary intuitions break down when we study microscopic, quantum-mechanical...
Synthetic piezoelectric crystals in the P321 crystal class have been a focus of substantial research that is largely driven by applications in high-temperature...
This paper details superconformal filling of submicrometer trenches with bright, dense copper from alkaline cupric ethylenediaminetetraacetic acid (EDTA)...
