To explain the observed features of k-space photoelectron images taken on off-stoichiometric Heusler Ni49.7Mn29.1Ga21.2 single-crystals in the cubic austenitic and pseudotetragonal martensitic phases, the images were simulated theoretically. Despite

Abstract In this work, we demonstrate and describe an effective method of protecting zirconium fuel cladding against oxygen and hydrogen uptake at both accident and working temperatures in water-cooled nuclear reactor environments. Zr alloy samples w

We present the results of simultaneous scanning-tunneling and frequency-modulated dynamic atomic force microscopy measurements with a qPlus setup. The qPlus sensor is a purely electrical sensor based on a quartz tuning fork. If both the tunneling cur

We studied initial stages of Fe and Si atoms interaction with the Zr(0001) surface. Fe and Si were deposited in-situ on the clean Zr surface up to coverage of one monolayer. Chemical state of Zr as a function of annealing temperature and the surface

In shape memory materials the fine twinned microstructure plays a fundamental role. Here we show that in the martensite phase of Ni-Mn-Ga Heusler alloy, the fine features of electronic structure are not caused by intrinsic electronic changes but meso

The arrangement of B~atoms in a doped Si(111)-$(\sqrt{3}\times\sqrt{3})R30^{\circ}$:B system was studied using near-edge x-ray absorption fine structure (NEXAFS). Boron atoms were deposited via segregation from the bulk by flashing the sample repeate
