The rapid diminution of fossil fuel stocks and ever-growing energy demand promotes the
researchers for the development of new functional materials to solve future energy demand …

High‐entropy alloy (HEA) nanoparticles hold great promise as tunable catalysts. Despite the
fact that alloy formation is typically difficult in oxygen‐rich environments, we found that Pt‐Ir …

Iridium dioxide (IrO2), ruthenium dioxide (RuO2), and their solid solutions (Ir1–x Ru x O2)
are very active electrocatalysts for the oxygen evolution reaction (OER). Efficient and facile …

Controlling the stoichiometry, structure, defects, size, and shape of engineered
nanomaterials (in the forms of powders, colloids, and thin films) is a fundamental issue in …

The effect of small changes in the specimen-to-detector distance on the unit-cell parameters
is examined for synchrotron powder diffraction in Debye–Scherrer (transmission) geometry …

Materials, when sintered at high temperatures, undergo structural changes on multiple,
hierarchical length scales but getting realtime information on these changes is difficult. To …

Understanding the nucleation and growth mechanisms of nanocrystals under hydro-and
solvothermal conditions is key to tailoring functional nanomaterials. High-energy and high …

Surface chemistry and core defects are known to play a prominent role in governing the
photophysical properties of nanocrystalline semiconductors. Nevertheless, investigating …

Hafnia, HfO2, which is a wide band gap semiconducting oxide, is much less studied than the
chemically similar zirconia (ZrO2). Here, we study the formation of hafnia nanocrystals from …

Spinel iron oxide nanoparticles of different mean sizes in the range 10–25 nm have been
prepared by surfactant-free up-scalable near-and super-critical hydrothermal synthesis …
