Transformation/dissolution characterization of tungsten and tungsten compounds for aquatic hazard classification

Integrated Environmental Assessment and Management, 2018
Abstract   The transformation/dissolution protocol (T/DP) for metals and sparingly soluble metal compounds was applied to determine the transformation/dissolution (T/D) characteristics of yellow tungsten trioxide, WO3; blue tungsten oxide, WOx, x taken as 2.9; tungsten disulphide, WS2; tungsten metal,

Flatband in a three-dimensional tungsten nitride compound

The Journal of Chemical Physics, 2020
Herein, the flatband of a W1N2 crystal is theoretically investigated. It is revealed that the flatband can be well-described by a tight-binding model of the N12 skeleton, where the dispersion of the flatband is governed by both the ppσ bonding strength (Vppσ) and the ppπ bonding strength (Vppπ) between the nearest-neighbor N atoms.

Tungsten Compounds and Their Application

1999
The chapter starts with a summary of the tungsten compounds with metallic elements (intermetallic compounds), and is followed by a more or less detailed description (depending on the importance of the respective compound) of the tungsten compounds with nonmetallic elements in sequence from the 14th to the 17th group of the Periodic Table.

Electrochromism Of A Tungsten Compound Film

SPIE Proceedings, 1987
ABSTRACT Electrochromic film has been prepared through liquid phase deposition (LPD) process with an aqueous solution containing an oxalatotungstate (V) complex, and its chemical and elec- trochromic properties have been investigated. Results showed that two redox couples exist on a cyclic voltammogram and that oxalate ligands would be present in the ...

Electrochemistry of tungsten compound film

SPIE Proceedings, 1990
From the viewpoint of improvement of energy efficiency in buildings, the so-called " smart window" with dynamic control of solar radiant energy throughput is very attractive, especially for the glass manufacturers. Several types of smart windows using chromogenic compounds have so far been proposed.

Microstructure and Microchemistry of Tungsten and Tungsten Compound Reactions with Aluminum Nitride Substrates

MRS Proceedings, 1989
AbstractA clear understanding of the bonding process in the cofired tungsten-aluminum nitride (W-AIN) metallized system is not currently available. Therefore, in an attempt to obtain a fuller understanding of this process, reactions between metallic W, tungsten trioxide (WO3), and calcium tungstate (CaWO4) with aluminum nitride have been studied using ...
