Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
99.8% pure compressed deuterium gas, in lot size of 850 L (142 g). Also sold by same supplier in the form of heavy water at price of 3940 USD per kg deuterium. [12] In 2016, Iran sold 32 tons of heavy water to United States for 1336 USD per kg deuterium. [13] 2: He: Helium: 0.0001785: 0.008 (2.216 × 10 14 kg) 24.0: 0.004 29: 2018: USGS MCS [14]
Carbonitriding is similar to gas carburization with the addition of ammonia to the carburizing atmosphere, which provides a source of nitrogen. Nitrogen is absorbed at the surface and diffuses into the workpiece along with carbon.
Aluminium titanium nitride (AlTiN) coated endmills using cathodic arc deposition technique. Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN; for aluminium contents higher than 50%) is a group of metastable hard coatings consisting of nitrogen and the metallic elements aluminium and titanium.

Today, cermet vacuum tube coatings have proved to be key to solar hot water systems. Ceramic-to-metal mechanical seals have also been used. Traditionally they have been used in fuel cells and other devices that convert chemical, nuclear, or thermionic energy to electricity. The ceramic-to-metal seal is required to isolate the electrical ...
Tubewells serve as the main source of drinking water in rural Bangladesh, with access to water for rural populations increasing from 65% in 1990 to 97% in 2015. [24] In 2015, 87% of the population had access to "improved" water, and the figure was identical to rural and urban areas. In 2015, there were still around 21 million lacking access to ...
An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most ...
