In military research, aluminium-molybdenum oxide, aluminium-Teflon and aluminium-copper(II) oxide have received considerable attention. [2] Other compositions tested were based on nanosized RDX and with thermoplastic elastomers. PTFE or other fluoropolymer can be used as a binder for the composition.
Other metal oxides can be used, such as chromium oxide, to generate the given metal in its elemental form. For example, a copper thermite reaction using copper oxide and elemental aluminum can be used for creating electric joints in a process called cadwelding, that produces elemental copper (it may react violently): 3 CuO + 2 Al → 3 Cu + Al ...
The coating is a chemical conversion of the substrate metal into its oxide, and grows both inwards and outwards from the original metal surface. Because it grows inward into the substrate, it has excellent adhesion to the substrate metal. A wide range of substrate alloys can be coated, including all wrought aluminum alloys and most cast alloys ...
Aluminium oxide is also used in preparation of coating suspensions in compact fluorescent lamps. In chemistry laboratories, aluminium oxide is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations. Additionally, small pieces of aluminium oxide are often used as boiling chips.
NMC materials have layered structures similar to the individual metal oxide compound lithium cobalt oxide (LiCoO 2). [3] Lithium ions intercalate between the layers upon discharging, remaining between the lattice planes until the battery gets charged, at which point the lithium de-intercalates and moves to the anode.

EPA research will provide data, models, test methods, and best practices to discover the acute health effects of carbon nanotubes and identify methods to predict them. [151] Cerium oxide: Nanoscale cerium oxide is used in electronics, biomedical supplies, energy, and fuel additives. Many applications of engineered cerium oxide nanoparticles ...
They used a nanostructured vanadium oxide, which is able to load two to three times more lithium ions onto the cathode than the layered lithium cobalt oxide. [66] In 2013 researchers announced a synthesis of hierarchical vanadium oxide nanoflowers (V 10 O 24 · n H 2 O) synthesized by an oxidation reaction of vanadium foil in a NaCl aqueous ...
Osmium(VIII) oxide is also used as a stain for lipids in optical microscopy. [26] OsO 4 also stains the human cornea (see safety considerations). A sample of cells fixed/stained with osmium tetroxide (black) embedded in epoxy resin (amber). The cells are black as a result of the effects of osmium tetroxide.
