This paper gives an overview of both the experimental and theoretical studies which have been recently performed in order to characterise the laser-electron beam dynamics of the European Storage Ring Free Electron Laser at ELETTRA.

Abstract Fluorine (F) and chlorine (Cl) are important volatiles in olivine its high-pressure polymorphs, which would significantly affect phase transition, melting temperature, physical property of the mantle. F Cl concentrations can be detected by electron probe microanalysis (EPMA). However, analytical accuracy precision impeded severe peak overlaps, low intensities traditional crystals, seco...

Transmission electron microscopic studies on CS2 hydrolase provide direct evidence for the existence of the hexadecameric catenane and octameric ring topologies. Reconstructions of both protein assemblies are in good agreement with crystallographic analyses of the catenane and ring forms of CS2 hydrolase.

Al–Ni–Er is an essential system in heat-resistant Al alloys. However, the aluminum-rich corner of this system, which has most practical application significance, not been fully studied. In work, phase equilibria are investigated via experiments and thermodynamic modeling. The isothermal sections Al-rich ternary at 600 700 °C were determined through equilibrated alloys combined with scanning ele...
