A large drive-in RF anechoic test chamber. Note the orange caution cones for size reference. Pyramid RAM. The grey paint helps to protect the delicate radiation-absorbent material. One of the most effective types of RAM comprises arrays of pyramid-shaped pieces, each of which is constructed from a suitably lossy material. To work effectively ...
Synthetic sapphire – single-crystal aluminum oxide (sapphire – Al 2 O 3) is a transparent ceramic. Transparent ceramics have recently acquired a high degree of interest and notoriety. Basic applications include lasers and cutting tools, transparent armor windows, night vision devices (NVD), and nose cones for heat seeking missiles.
Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.
Robotic arm applying paint on car parts. Automotive paint is paint used on automobiles for both protective and decorative purposes. [1] [2] Water-based acrylic polyurethane enamel paint is currently the most widely used paint for reasons including reducing paint's environmental impact.

Many polycarbonate grades are used in medical applications and comply with both ISO 10993-1 and USP Class VI standards (occasionally referred to as PC-ISO). Class VI is the most stringent of the six USP ratings. These grades can be sterilized using steam at 120 °C, gamma radiation, or by the ethylene oxide (EtO) method. [20]
While the opening round of the 2024 NFL playoffs didn’t provide many nail-biting finishes, it did set up some must-see divisional round clashes. The two No. 1 seeds return from their well-earned ...
The key advantage of this type of ceramic material is the versatility afforded by the use of polymeric precursors in terms of processing and shaping. Polymer derived ceramics can be additively manufactured (3D printed) by means of fused filament fabrication , [ 4 ] stereolithography that uses photopolymerization of preceramic polymers . [ 5 ]
The secret to this easy recipe lies in the tangy lemon-and-garlic drizzle that picks up the savory flavors left in the pan. Pan-searing chicken tenders locks in moisture while crisping up the outside.
