Advanced Functional Materials for Marine Energy Utilization

open access: yesInterdisciplinary Materials, Volume 5, Issue 3, Page 317-356, May 2026.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

Investigations on the Wettability of Silicate Glass Melts on Tantalum, Niobium, and Their Oxides

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT In the past, niobium and tantalum oxides were primarily investigated for potential applications in advanced optics, electronics, and photonics due to their unique physical properties. In recent heating microscopy experiments, we observed interesting wetting characteristics of silicate glass melts in contact with these materials: unlike other ...

Ferroelectricity in empty tetragonal tungsten bronzes

open access: yes, 2017
In this work, in-depth structural and electrical characterisation is used to study a family of “empty” tetragonal tungsten bronzes (TTBs), A2₄A1₂B1₂B2₈O₃₀. An initial investigation into the effect of the A1-cation size on the properties of empty Ba₄R₀.₆₇◻₁.₃₃Nb₁₀O₃₀ TTBs (where R is the A1-cation and R = La, Nd, Sm, Gd, Dy and Y; ◻ = vacancy) was ...
