In mass spectrometry, direct analysis in real time (DART) is an ion source that produces electronically or vibronically excited-state species from gases such as helium, argon, or nitrogen that ionize atmospheric molecules or dopant molecules. The ions generated from atmospheric or dopant molecules undergo ion-molecule reactions with the sample ...
Soviet 125 mm HEAT BK-14. The general public remained in the dark about shape charge warheads, even believing that it was a new secret explosive, until early 1945 when the US Army cooperated with the US monthly publication Popular Science on a large and detailed article on the subject titled "It makes steel flow like mud".

Tranquilizer darts are related to the darts for blowguns, but include a hypodermic needle and a hollow reservoir resembling a syringe, which is generally filled with sedatives or other drugs. These are launched from a dart gun using compressed gas, a tuft of fibers at the back of the missile serving as both fletching and wadding .
DARDO ("Dart" in Italian) originally known as Breda Type-70, [1] also marketed as the OTO Twin 40L70 Compact, [2] is a close-in weapon system (CIWS) built by the Italian companies Breda and Oto Melara.
The V3E A-Darter (Agile Darter) is a modern short-range infrared homing ("heat seeking") air-to-air missile, featuring countermeasures resistance with a 180-degree [4] look angle and 120-degrees per second track rate, [5] developed by South Africa's Denel Dynamics (formerly Kentron) and Brazil's Mectron (now SIATT), Avibras and Opto Eletrônica (acquired by AKAER).

High-density alloys of tungsten with nickel, copper or iron are used in high-quality darts [96] (to allow for a smaller diameter and thus tighter groupings) or for artificial flies (tungsten beads allow the fly to sink rapidly).
A dart gun is an air rifle that fires a dart. [1] The dart is tipped with a hypodermic needle and filled with a sedative , [ 2 ] vaccine [ 3 ] or antibiotic . [ 4 ] A dart gun containing a sedative is called a tranquillizer gun ( also spelled tranquilizer gun , tranquilliser gun or tranquiliser gun ), derived from the word "tranquil", which ...
