1.1 Background Developing efficient energy conversion devices that are in line with the
conservation of the natural environment is a critical challenge for modern society. Fossil …

Conspectus The lone pair has been a known feature of the electronic structure of molecules
for over 100 years. Beginning with the pioneering work of Lewis and others that was later …

In this review, we describe the creation of a large database of thermoelectric materials
prepared by abstracting information from over 100 publications. The database has over 18 …

Two inorganic–organic hybrid compounds with zero-dimensional crystal structures,
tetramethylphosphonium tetrachloroferrate (III)(compound 1,[(CH3) 4P][FeCl4]) and …

As a potential multifunctional phase transition material, the organic–inorganic hybrid
perovskite has attracted extensive attention in recent years. Here, we report the single …

The emergence of scalar Higgs-type amplitude modes in systems where symmetry is
spontaneously broken has been a highly successful, paradigmatic description of phase …

To produce directly combustible hydrogen from water, highly active, acid-resistant, and
economical catalysts for oxygen evolution reaction (OER) are needed. An electrocatalyst …

Abstract Pyrochlore Pr 3+ 2+ x Zr 4+ 2− x O 7− x/2 samples in the form of both powders (−
0.02≤ x≤ 0.02) and bulk single crystals have been studied to elucidate the dependence of …

Metal oxides are some of the most promising candidates as electrocatalysts for electrical‐
energy‐storage (EES) systems. Particularly, perovskite and pyrochlore oxides have been …

To switch quadratic nonlinear optical (NLO) effects has become an exciting branch of the
NLO material science. However, solid-state molecular crystals showing tunable and …
