The complex band structure and carrier decay response upon photoexcitation of the chiral semiconductor tellurium remain to be unveiled. Here, the authors report unusual dynamic band modifications in Te near band-edge structure due to photoinduced sym

The Prandtl-Tomlinson (PT) model is the most widely used and successful minimalistic model to describe atomistic scale friction. It can describe the thermally activated, stress assistant process which shows stick-slip frictional behavior. The relatio

Cold atmospheric plasmas are currently gaining increasing attention for cancer therapy. However, very limited studies regarding the interaction mechanisms between plasma species and tissues are available. We report the interaction of plasma produced

Liquid–vapor molecular dynamics (LVMD) simulations are performed to reinvestigate the phase transition and solvation force oscillation behavior of a simple argon liquid film confined between two solid surfaces. Our simulations present a novel scena

The pop-in effect in nanoindentation of metals represents a major collective dislocation phenomenon that displays sensitivity in the local surface microstructure and residual stresses. To understand the deformation mechanisms behind pop-ins in metals

Mechanical force can evaluate intramolecular interactions in macromolecules. Because of the rapid motion of small molecules, it is extremely challenging to measure mechanical forces of nonspecific intermolecular interactions. Here, we used optical tw

Biological host molecules such as β-cyclodextrins (β-CDs) have been used to remove cholesterol guests from membranes and artery plaques. In this work, we calibrated the host-guest intermolecular mechanical forces (IMMFs) between cholesterol and cyc

Friction measurements by an atomic force microscope (AFM) frequently showed regular stick-slip friction signals with atomic-scale resolutions. Typically, for an AFM metal tip sliding on a metal crystal surface, the microstructure of the tip made from

We present a predict-correct trajectory propagation (PCTP) method for simulating nonequilibrium driven dynamics of the long-time bond-breaking event in an atomic force microscope (AFM). Whereas the parallel replica method can extend the time scale of
