    The definition of active block is given from the angles of crustal deformation and strain. The movement and strain parameters of active blocks are estimated according to the unified velocity field composed of the velocities at 1598 GPS stations obtained from GPS measurements carried out in the past years in the Chinese mainland and the surrounding areas.

  • Theoretical Study of the Electronic Structures of HfB2

    2004-9-3 · The electronic structures of HfB2(0001)-X (X = Li through Ne) surfaces have been calculated using density functional theory (DFT) and properties such as adsorption sites adsorption energies oscillation energies and electron densities have been obtained. Experimentally the HfB2(0001) clean surface is terminated by a (1 1) Hf layer and our calculation revealed that all adsorbed elements

    2021-1-22 · Lithium was discovered by Johan August Arfvedson (SE) in 1817. The origin of the name comes from the Greek word lithos meaning stone apparently because it was discovered from a mineral source whereas the other two elements sodium and potassium were discovered from plant sources.It is a soft silvery-white metal and it s the lightest of metals.

  • Abrupt but smaller than expected changes in surface air

    The COVID-19 lockdowns led to major reductions in air pollutant emissions. Here we quantitatively evaluate changes in ambient NO2 O3 and PM2.5 concentrations arising from these emission changes in 11 cities globally by applying a deweathering machine learning technique. Sudden decreases in deweathered NO2 concentrations and increases in O3 were observed in almost all cities.
