Annealed Pyrolytic Graphite (APG), also known as Thermally Annealed Pyrolytic Graphite (TPG), [1] is a form of synthetic graphite that offers excellent in-plane thermal conductivity. As with pyrolytic carbon or pyrolytic graphite (PG), APG is also low in mass, is electrically conductive , and offers diamagnetic properties that allow it to ...
The level of purity, or the relative lack of contamination, affects the quality of the oxide layer or annealed surface. The method of delivery affects growth rate, uniformity, and electrical performance. Oxidation and annealing are common steps in the manufacture of such devices as microelectronics and solar cells.
In the semiconductor industry, silicon wafers are annealed to repair atomic level disorder from steps like ion implantation. In the process step, dopant atoms, usually boron , phosphorus or arsenic , move into substitutional positions in the crystal lattice, which allows these dopant atoms to function properly as dopants in the semiconducting ...
The setup that utilizes a laboratory X‑ray source (Metal Jet) in combination with a von Hamos full cylinder optic with Highly Annealed Pyrolytic Graphite (HAPG) crystal and a CCD detector. This allows obtaining spectra in the 2.4-9 keV range. Moreover, this spectrometer is an alternative to synchrotron-based beamlines for concentrated samples ...
A small sample of aerospace grade carbon-fibre/epoxy laminate. In materials science, a composite laminate is an assembly of layers of fibrous composite materials which can be joined to provide required engineering properties, including in-plane stiffness, bending stiffness, strength, and coefficient of thermal expansion.
Solvent vapor annealing (SVA) is a widely used technique for controlling the morphology and ordering of block copolymer (BCP) films. [1] [2] [3] By controlling the block ratio (f = NA/N), spheres, cylinders, gyroids, and lamellae structures can be generated by forming a swollen and mobile layer of thin-film from added solvent vapor to facilitate the self-assembly of the polymer blocks.

Tempered glass can be made from annealed glass via a thermal tempering process. The glass is placed onto a roller table, taking it through a furnace that heats it well above its transition temperature of 564 °C (1,047 °F) to around 620 °C (1,148 °F). The glass is then rapidly cooled with forced air drafts while the inner portion remains ...
Use of float glass at Crystal Palace railway station, London. Float glass is a sheet of glass made by floating molten glass on a bed of molten metal of a low melting point, typically tin, [1] although lead was used for the process in the past. [2]
