A method is disclosed for coating a projectile for use in an ammunition cartridge. A polymer jacket is applied to an undersized projectile core of a first standard caliber to bring the outer dimensions of the jacketed projectile into compliance with those of a second, larger caliber projectile. The polymer jacket coating may produce a non-uniform outer diameter of the polymer jacketed projectile and may include a plurality of circular cavities defined therein. The polymer-jacketed projectile may be a bullet for pistol or rifle ammunition, or a pellet, or shot for use in a shotgun shell.

There is provided a method of treating a nickel base super alloy (NiSa) article. First, the NiSa article having fine grains is obtained. The NiSa article has a uniform distribution of the fine grains and substantially uniform mechanical properties throughout. One or more regions within the NiSa article are mechanically deformed. Then, the NiSa article is heat treated to obtain coarse grains in the one or more regions, the coarse grains having a size that is larger than that of the fine grains of the NiSa article outside of the one or more regions.

A method of fabricating a burner element for an abatement apparatus is disclosed. The method comprises: injection moulding a charge comprising metal particles and a flow compound into a mould defining the burner element to produce a moulded burner element; and sintering the moulded burner element. In this way, injection moulding is used to produce the burner element, which provides far more flexibility regarding the design and properties of the burner element and avoids the necessity of incorporating a perforated support into the burner element. This allows burner elements of more intricate design to be produced, as well as burner elements which are thinner than those produced using existing techniques, which increases the volume of a combustion chamber defined by that burner element for any external burner element size, which in turn increases the amount of effluent gas that can be treated for any burner size.

The invention relates to a sintered metal material comprising at least one magnetic part, characterised by directional through-pores having a size of between 1 and 100 μm, said material having a density varying by less than 20% from one sample of 1 cm3 to another taken from a one-piece part made from the material.

Methods of forming microwires or nanowires, microwires or nanowires formed using the method, and electronic devices and semiconductor components including the wires. A method of forming a microwire or nanowire includes disposing a plurality of metal particles in a portion of a channel that is a nanochannel or a microchannel. The method includes etching the metal particles with an activation agent to form a flux that penetrates an additional portion of the channel. The flux includes an etching product of the activation agent and the metal particles. The method includes allowing the activation agent to at least partially evaporate to form a wire that is a microwire or a nanowire.
