Atomic resolved material displacement on graphite surfaces by scanning tunnelling microscopy [PDF]
, 1992 Atomic scale modifications and subsequent atomic resolution imaging has been achieved on the highly oriented pyrolytic graphite surface in air. Application of short pulse voltages, above a minimum threshold voltage of 3.5 V, across the tunneling gap ...

On fast charged particles scattering in a thin crystalline undulator
Physics Letters B, 2019 The scattering of fast charged particles in a thin silicon crystalline undulator is considered under conditions when all the particles of the beam undergo above-barrier motion with respect to the bent crystalline atomic planes. The consideration is based

Effect of Gd addition on microstructure and corrosion behaviors of Mg–Zn–Y alloy
Journal of Magnesium and Alloys, 2016 The Mg97-xZn1Y2Gdx alloys were prepared by as-casting method. Corrosion performance of alloys was evaluated by using potentiodynamic polarization, hydrogen evolution rate and mass loss measurements in 3% sodium chloride solution at room temperature.

Ab initio study of the volume dependence of dynamical and thermodynamical properties of silicon
, 1995 Motivated by the negative thermal expansion observed for silicon between 20 K and 120 K, we present first an ab initio study of the volume dependence of interatomic force constants, phonon frequencies of TA(X) and TA(L) modes, and of the associated mode ...

Atomic Volumes of Carbon and Hydrogen [PDF]
Nature, 1926 PROF. INGOLD has introduced an important modification of Baeyer's strain theory, which brings the calculated ring strains into closer agreement with the thermal data of the cycloparaffins and with the general chemistry of the formation and decomposition of this series of saturated hydrocarbons (Trans. Chem. Soc., 119, 305, 1921).

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
