Electron‐Rich Nickel Enabled by Charge Transfer in Multimetal Nanostructures for Efficient Ammonia‐to‐Hydrogen Conversion

Advanced Science, EarlyView.
A charge‐transfer‐engineered Ni catalyst derived from an atomically mixed layered precursor enables efficient ammonia‐to‐hydrogen conversion. Cr‐to‐Ni electron transfer creates electron‐rich Ni active sites that favor NH3 adsorption, modify the dehydrogenation energetics, and weaken N2 binding to facilitate product desorption. This electronically tuned

On the confluence of ultrafast high‐temperature sintering and flash sintering phenomena

Journal of the American Ceramic Society, 2023
Abstract Ultrafast high‐temperature sintering (UHS) and flash sintering are novel methods for rapid sintering of ceramics, often completed in just a few seconds. Here, we show that both also share two additional features: an abrupt rise in electrical conductivity, which is electronic, and electroluminescence.

A Review of Ceramic Sintering and Suggestions on Reducing Sintering Temperatures

Advanced Performance Materials, 1997
Theories and applications associated with sintering of ceramics and reducing of sintering temperature are reviewed. The whole sintering process is divided into three sub-processes as powder preparation, compaction and sintering, and each sub-process is discussed in terms of its possible contribution to the reducing of sintering temperature.

Low sintering temperature of ZnNb2O6 for silver co-sintering

Ceramics International, 2014
The purpose of this study is the making of multilayer type I capacitors composed of ZnNb2O6 co-sintered with silver electrodes. In order to lower the sintering temperature, we have mixed three commercially available glass frit powders with ZnNb2O6. The sintering behaviours were studied by thermomechanical analysis (TMA).

Dependence of the mechanical properties of sintered hydroxyapatite on the sintering temperature

Materials Science and Engineering: A, 2006
Abstract This paper discusses the dependence of microstructure and mechanical properties of sintered hydroxyapatite (HA) on the temperature of sintering. Hydroxyapatite powder was prepared by the precipitation method and its purity and crystallinity were evaluated via XRD.
