PARIS — Photonic computing hardware developer LightOn integrated a photonic coprocessor into the Jean Zay supercomputer, one of the 500 most powerful computers in the world. The integration of the optical processing unit into a high-performance computer is reportedly the first demonstration of its kind. The insertion of the coprocessor is a light-based alternative to electrical current, which is commonly used to transmit and processor information in computers. The work stems from a pilot program with GENCI (Grand équipement national de calcul intensif) and IDRIS (Institute for Development and Resources in Intensive Scientific Computing). The LightOn photonic coprocessor will be available to selected users of the Jean Zay research community over the next few months, the company said.

ULSAN, South Korea — Chemical companies SK Geo Centric and Tokuyama will launch a joint venture to produce and sell high-purity isopropyl alcohol, a cleaner for liquid crystal displays and wafers for the semiconductor industry, following an investment of roughly 120 billion KRW ($100.92 million) from Tokuyama. The 50-50 joint venture will lead to the development of a manufacturing plant that will begin operations in 2023.

CHARLOTTE, N.C. — Satellite imagery collection company Satellogic will construct a manufacturing facility in the Netherlands. The 5700-sq-ft facility will accelerate the assemblage of satellites and accommodate manufacturing, integration, and testing equipment. The company’s vice president of manufacturing operations, Gustav Wenhold, will lead operations at the facility. The company expects the facility to reach full production capacity of 25 satellites per quarter by the third quarter of 2023. Satellogic said its existing assembly, integration, and test facility in Uruguay will mainly function as a pilot plant for next-generation satellites. Satellogic is expected to list as a public company following a merger with a specialty purpose acquisition company that the company said is projected to close by the end of the fourth quarter of 2021.

liquid crystal
A type of material that possesses less geometrical regularity or order than normal solid crystals, and whose order varies in response to alterations in temperature and other quantities. Liquid crystals are characterized by phase varieties, including cholesteric, nematic and smectic. The optical properties of liquid crystals are familiar from their use in displays, known as LCDs.
