Photocatalysis is one potential solution to the energy and environmental crisis and greatly
relies on the development of the catalysts. Niobium pentoxide (Nb2O5), a typically nontoxic …

In this study, we show from helium (He) plasma irradiation to tantalum and iron surfaces that
morphology changes in nanoscale occur on the both metals. In particular, from systematic …

High-performance lithium-ion batteries are important for developing sustainable energy.
However, there is a shortage of advanced energy storage materials. K2Nb8O21 is a novel …

The goal of this work is to assess Ta as a potential plasma-facing material for future fusion
reactors in terms of its response to high-flux, low-energy He+ ion irradiation. Ta samples …

In the zinc electrowinning process, lead anodes have been the main cause of lead pollution,
resulting in environmental and ecological imbalances. To address this issue, this study …

Group 5 elements (niobium and tantalum) and group 6 elements (molybdenum and
tungsten) were exposed to helium plasma, and the resulting surface structures were …

Thermophysical property of a nanostructured tungsten layer formed on a tungsten film was
investigated. A 1-µm-thick tungsten film deposited on a quartz glass substrate was irradiated …

In the present study, we report on tuning the surface porosity on vanadium surfaces using
high-flux, low-energy He+ ion irradiation as function of sample temperature. Polished, mirror …

Fiberform nanostructured niobium (Nb) was fabricated by one step helium (He) plasma
irradiation. He ion implantation formed He nano‐bubbles on a Nb plate and led to formation …

Difference of helium (He) agglomeration energies between period 6 elements, tantalum
(Ta), tungsten (W), iridium (Ir) and gold (Au), is illustrated by using first principles …
