Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

EcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...

Niobium Pentoxide Films with High Laser-Induced Damage Threshold under High Temperature Environment

Photonics, 2022
Laser damage resistance of films is the key to the performance and durability of high-power laser systems. High temperature, however, often leads to a certain degree of decline in film properties.

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

Journal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Mechanochemical Synthesis of Niobium Pentoxide Nanoparticles

MATERIALS TRANSACTIONS, 2001
Acicular α-FeOOH particles are formed through aging of ferric oxyhydroxide colloidal solution formed by the neutralization of FeCl 3 aqueous solution by NaOH. The effect of foreign ion addition to the colloidal solution on the formation and morphology of α-FeOOH particles has been investigated.
