W–A12O3 Nanoscale Composite Using Ammonium Paratungstate (APT) And Al Powder Mixture

SEM image of tungsten-Aluminium composite

In recent years, nanometered-scale tungsten and its compounds have attracted much focus because of their superior physical and mechanical properties. A wide variety of methods such as mechanical alloying, combustion synthesis, physical vapor deposition (WD), electric wire explosion etc. have been used to synthesize nanostructured tungsten. Among these techniques, mechanical alloying and mechanochemical synthesis (CS) are very attractive. Simple and inexpensive equipments are required, and it can be conducted at ambient temperature. Indeed MCS uses mechanical energy to active chemical reactions.

Hydrothermal Preparation of Nanoscale Cesium Tungsten Bronze Using Ammonium Paratungstate

SEM Image of Cs0.3WO3 particles

Recently, two-dimensional (2D) nanomaterials has attract a great attention due to its unknown physical, chemical, electrical and optical properties. For instance, graphene nanosheets mechanically exfoliated from graphite show very high carrier mobility, excellent thermal conductivity and optical properties, which inspires lots of other 2D materials such as graphene oxide (GO) , hexagonal boron nitride (h-BN), transition metal carbides and carbonitrides (MXenes), as well as graphitic carbon nitride (g-C3N4) 161 are well studied.

Nanoscale Al/WO3 for Metastable Intermolecular Composites from Ammonium Paratungstate

SEM Image of WO3

Metastable intermolecular composite (MIC) materials is an intimate mixture of two or more compounds of which at least two are exothermically reactive. However, conventional thermites have a significantly lower reactive power. In contrast, MIC materials, while retaining the high energy density, can have a significantly higher reactive power than conventional thermites.
