A novel Multi-Phase Flash Sintering (MPFS) technique for 3D complex-shaped ceramics
This work demonstrates the first proof-of-concept of Multi-Phase Flash Sintering (MPFS). This novel technique essentially consists of applying a rotating electric field to the sample by means of a multi-phase voltage source as furnace temperature increases. Several...
Optoelectronic Devices Based on Scaffold Stabilized Black-Phase CsPbI3 Nanocrystals
The optoelectronic properties of lead halide perovskites are intimately related to their crystalline phase. For the case of cesium lead iodide (CsPbI3) several polymorphs meet the Goldschmidt tolerance factor, which determines their stability, and form broad band...![Asymmetric synthesis of dibenzo[b,d]azepines by Cu-catalyzed reductive or borylative cyclization](https://www.ciccartuja.es/wp-content/uploads/sites/4/2024/11/portada_revista_febrero-1080x675.jpg)
Asymmetric synthesis of dibenzo[b,d]azepines by Cu-catalyzed reductive or borylative cyclization
A copper-catalyzed asymmetric intramolecular reductive cyclization for the synthesis of dibenzo[b,d]azepines is described. Use of 2′-vinyl-biaryl-2-imines as substrates and in situ formed [CuI/(Ph-BPE)] as the catalyst enables the synthesis of 7-membered bridged...
Supported σ-Complexes of Li‒C Bonds from Coordination of Monomeric Molecules of LiCH3, LiCH2CH3 and LiC6H5 to MoMo Bonds
LiCH3 and LiCH2CH3 react with complex [Mo2(H)2(μ-AdDipp2)2(thf)2] (1 thf) with coordination of two molecules of LiCH2R (R=H,CH3) and formation of complexes [Mo2{μ-HLi(thf)CH2R}2(AdDipp2)2], 5 LiCH3 and 5 LiCH2CH3 , respectively (AdDipp2=HC(NDipp)2; Dipp=2,6-iPr2C6H3 ;...
Plasma Engineering of Microstructured Piezo – Triboelectric Hybrid Nanogenerators for Wide Bandwidth Vibration Energy Harvesting
We introduce herein the advanced application of low-pressure plasma procedures for the development of piezo and triboelectric mode I hybrid nanogenerators. Thus, plasma assisted deposition and functionalization methods are presented as key enabling technologies for...
