Termite nasute illustration (since reclassified as Nasutitermes corniger). The fontanellar gun is a termite defense mechanism in the form of a horn-like frontal projection (nasus) on the head of the soldier caste which is capable of expelling chemical weaponry at a distance, a trait exclusive to the subfamily Nasutitermitinae.
Termites of the subfamily Nasutitermitinae can project a sticky fluid from a nozzle on their heads. They can use this fontanellar gun accurately, over a range of many centimeters, even though the termite is blind, possibly using auditory or olfactory cues instead. A number of vertebrates also use liquid projectiles.
This process is commonly used for the treatment of drywood termites and/or bedbugs, using sulfuryl fluoride as the pesticide (sulfuryl fluoride is a naturally occurring gas, used in much higher concentration than found in the natural atmosphere, and which leaves no physical residue). The fumigated structure can be re-occupied after the tent has ...
Cold spray additive manufacturing (CSAM) (also called cold spray 3D printing) is a particular application of cold spraying, able to fabricate freestanding parts or to build features on existing components. During the process, fine powder particles are accelerated in a high-velocity compressed gas stream, and upon the impact on a substrate or ...
Specially designed cartridges and conversion kits can be used together to convert semi-/fully automatic firearms into wax bullet guns, used in tactical training for police and military. Wax bullets have been in use for over a century in military training, target shooting and confrontational shooting competitions where using real metallic ...

An agricultural aircraft applies low-insecticide bait against western corn rootworm.. Pest control is the regulation or management of a species defined as a pest; such as any animal, plant or fungus that impacts adversely on human activities or environment. [1]
The D-gun atomises the powder feedstock into extremely small particles (80–95% of particles by total number are of size <100 nm). This means proper extraction facilities are required for inhalation safety purposes. Also isolation of the D-gun is recommended to avoid operators breathing in the dangerous dust and fumes. [14]
