Furan‐Substituted Phosphine‐Oxide as an Efficient Interfacial Modifier for Wide‐Bandgap Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.

Rate‐Adaptive Site Transformation Catalyst for Parallel Water Dissociation and Hydrogen Adsorption in Alkaline Hydrogen Evolution

Advanced Functional Materials, EarlyView.
This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

Chemical Diversity for Tailoring Negative Thermal Expansion

Chemical Reviews, 2022
Negative thermal expansion (NTE), referring to the lattice contraction upon heating, has been an attractive topic of solid-state chemistry and functional materials. The response of a lattice to the temperature field is deeply rooted in its structural features and is inseparable from the physical properties.

Negative Thermal Expansion Coefficient

2019 IEEE 2nd Ukraine Conference on Electrical and Computer Engineering (UKRCON), 2019
Physical nature of negative thermal expansion coefficient ($\alpha$) in polar-sensitive dielectrics and semiconductors is explained. Physical features of inter-atomic bonds in crystals are manifested in their thermal expansion; in the polar dielectrics it is a peculiar polar-sensitive structure, arisen due to compensation of atoms electronegativity ...
