A primer composition is provided having a primary explosive and an oxidizer system containing at least one tungsten oxide or one tungstate compound. The oxidizer system can by non-hydroscopic and non-toxic. The primer can include reducing agents, sensitizers, binders and gas producing agents. The primer composition generally is applicable to any application or device that employs ignition of a propellant, a fuel, a relay charge, a delay charge, or a booster charge, including, but not limited to, air bag gas generator systems, signaling devices, ejection seats, small, medium or large arms ammunition primers, and the like.

Electrocatalytic polyaniline-derived mesoporous carbon nanoparticles and methods of synthesizing and using the same are provided.

A composition of matter and method of forming a radiation shielding member at ambient temperatures in which the composition of matter includes a cold-fired chemically bonded oxide-phosphate ceramic cement matrix; with one or more suitably prepared and distributed radiation shielding materials dispersed in the cold-fired chemically bonded oxide-phosphate ceramic cement matrix.

A method for producing the pentazolate anion, includes at least the oxidation of a phenolic arylpentazole by a particular hypervalent iodine oxidant in the presence of a base.

A method for producing the pentazolate anion, includes at least the oxidation of a phenolic arylpentazole by a particular hypervalent iodine oxidant in the presence of a base.

A method for delithiating a lithium and transition metal nitride. The method involves mixing an oxidising agent with the lithium and transition metal nitride and recovering the material obtained. The transition metal may be Mn, Fe, Co, Ni, Cu, or a mixture thereof. The material obtained by the method may be used as a negative electrode material for a lithium-ion battery.

The invention relates to an apparatus for the visualisation of a print on an object, the apparatus comprising: a base comprising a heating element in thermal communication with a receptacle for storing an agent, a housing to provide a sealed chamber; and a port for applying a vacuum to, or releasing a vacuum from, the sealed chamber. The invention is particularly for the visualisation of a fingerprint such as a latent fingerprint. The invention also relates to a system incorporating the apparatus with a cartridge and agent, and associated methods and uses for visualising a print on an object.
