Abstract Highly transparent 0.5 and 1.0 at% Pr-doped Y 2 O 3 ceramics were fabricated by vacuum sintering plus hot isostatic pressing (HIP) treatment. The selection of suitable pre-sintering temperatures right microstructures before HIP was critical to obtain high density the final sintered bodies. well-densified had pore-free with an average grain size about 1 µm. It also found that charge states Pr ions could be changed through regulating annealing atmospheres, resulting in different...
AgNbO3-based antiferroelectric ceramics can be used to prepare dielectric ceramic materials with energy storage performance. However, their efficiency is much lower than that of relaxors, which one the biggest obstacles for applications. To overcome this problem, AgNbO3 co-doped Eu3+ and Ta5+ at A- B-sites were prepared in work. The Ag0.97Eu0.01Nb0.85Ta0.15O3 sample has a Wr 6.9 J/cm3 an η 74.6%. ultrahigh density been ascribed synergistic effect increase breakdown electric field,...

Abstract MXene is a promising two‐dimensional (2D) material for energy storage applications owing to its exceptional conductivity and controllable surface chemistry. Currently, aqueous etching methods the preparation of sheets require substantial quantity HF or HCl, leading issues such as structural defects in severe corrosiveness due acidic nature these etchants. This study proposes mild situ strategy materials through hexafluoro complex anion hydrolysis etching. Etching accomplished by...
Organic solar cells (OSCs) could benefit from the ternary bulk heterojunction (BHJ), a method that allows for fine-tuning of light capture, cascade energy levels, and film shape, in order to increase their power conversion efficiency (PCE). In this work, third components PM6:Y6 PM6:BTP-eC9 BHJs are set four star-shaped unfused ring electron acceptors (SSUFREAs), i.e., BD-IC, BFD-IC, BD-2FIC, BFD-2FIC, facilely synthesized by direct C–H arylation. The SSUFREAs all show complete complementary...
