Mandrel forging is a forging operation that is done with the help of a tool called mandrel. A mandrel is a blunt ended tool or a rod that is sued to enlarge or retain the cavity in a hollow metal product during forging.
Aluminium gallium nitride is a semiconductor material and an alloy of aluminium nitride and gallium nitride. When grown on GaN, it gives rise to fixed charges at the interface stemming from piezoelectric effects.
Lead sulfide is an inorganic compound with the chemical formula PbS. It is also known as galena, which is the principal ore and important compound of lead. It is one of the earliest materials to be used as a semiconductor as it tends to crystallize in sodium chloride.
Copper (I) oxide or cuprous oxide is an inorganic compound having the formula Cu2O. It is a principal oxide of copper. It is a red-colored solid, which is a component of certain antifouling paints. The compound may be red or yellow based on the particle size.

Stephen Ball, Product Marketing Manager for Nanoparticle and Molecular Characterization at Malvern Instruments, tells AZoM how the latest addition to the company’s range of detectors for size exclusion chromatography is all about delivering choice.
Aluminum indium arsenide, also called as indium aluminum arsenide, is a semiconductor material having larger bandgap and same lattice constant as that of GaInAs.
Lanthanum calcium manganate crystals have transition temperature that tends to increase at high doses of electron irradiation, which in turn stimulates persistence of magnetic polarons up to higher temperatures.
Copper indium gallide selenide is an I-III-VI semicondutor material composed of selenium, gallium, indium and copper. It is a tetrahedrally bonded semiconductor largely found in chalcopyrite mineral.
Copper zinc tin sulfide is a quaternary semiconducting compound that has favorable optical and electronic properties similar to copper indium gallium selenide. It can be obtained from chalcopyrite structure by substituting the trivalent In/Ga with a bivalent Zn and IV-valent Sn.
Silver gallium sulfide has high short wavelength transparency edging at 550nm, excellent bulk quality across the transmission range, except for residual e-ray absorption centered at 1.8µm. Surface absorption of silver gallium sulfide may increase with time.
