A vein structure, which becomes more pronounced with increasing ion dose, was found on the surface of polycrystalline HOPG (highly oriented pyrolytic graphite) implanted by ex situ C+ (up to 1.8 × 1017 ions/cm2), and in situ Ar+ in a transmission el

β-Ga2O3 was suggested to have excellent irradiation hardness which makes β-Ga2O3-based devices extremely attractive for nuclear and space applications. To discern the fundamental nano-scale structural changes with irradiation, an in situ irradiatio

Solution-processed iron selenide nanocrystals (NCs) have recently attracted considerable attention in electrocatalysis water splitting. Nevertheless, a primary challenge in current iron-based NCs chemical synthesis is controlling phase purities betwe

Nanocrystalline Cu2O thin films have been grown on air cleaved NaCl(100) substrates at relatively low temperatures (25 °C ≤ Tsub ≤ 300 °C) by Pulsed Laser Deposition. Structural analysis by Transmission Electron Microscopy(TEM) revealed that fi

The limited efficiency of Cu2ZnSn(SSe)4 (CZTSSe) solar cells has been widely attributed to band tailing due to high densities of CuZn and ZnCu antisite defects. It has been proposed that partial replacement of Cu by Ag should reduce the antisite defe

Mrozowski nano-cracks in nuclear graphite were studied by transmission electron microscopy and selected area diffraction. The material consisted of single crystal platelets typically 1–2 nm thick and stacked with large relative rotations around the

Mn-doped ZnO nanowires prepared by chemical vapor deposition (CVD) were obtained in the temperature range of 450–500°C. X-ray diffraction patterns, SEM and TEM images indicate that crystals with a hexagonal structure grow along the c axis. At low

Experimental ferritic 9Cr–1Mo steels exposed at high temperature and pressure to CO2-based gas undergo oxidation and carburisation. Oxidation proceeds initially as a protective phase with parabolic kinetics (stage I). At high temperatures and longe

Hexagonal boron nitride (h-BN) has been predicted to exhibit an in-plane thermal conductivity as high as ~ 550 W m−1 K−1 at room temperature, making it a promising thermal management material. However, current experimental results (220–420 W m
