Solidia CO2-curing cement technology

Solidia CO2-curing cement technology is a process in which low-lime calcium silicate cement hardens by reacting with carbon dioxide instead of water, developed by Solidia Technologies.

Solidia low-lime cement cured with CO2

Solidia Cement is a low-lime calcium silicate cement developed by Solidia Technologies that hardens by reacting with CO2 instead of water, cutting concrete's carbon footprint by up to 70%.

Solidification

Solidification is the phase transformation in which a liquid becomes a solid when cooled below its freezing temperature, proceeding by nucleation and growth of dendrites and grains.

Solidity

Solidity is a statically typed, object-oriented, curly-bracket programming language influenced by C++ for writing smart contracts, principally on Ethereum and other EVM-compatible blockchains, with support for inheritance and libraries.

SolidJS

SolidJS is a declarative JavaScript library for building user interfaces, created by Ryan Carniato and first released as version 1.0 in June 2021. It uses fine-grained reactivity to update the DOM directly, without a virtual DOM.

SolidSail

SolidSail is a wind propulsion system for large ships developed by the French shipyard Chantiers de l'Atlantique, using rigid composite sails on tilting carbon masts.

SOLIDWORKS

SOLIDWORKS is a parametric, feature-based 3D CAD program for mechanical product design, founded in 1993 and acquired by Dassault Systèmes in 1997 for about $310 million.

Solntsevsky Coal Mine

The Solntsevsky Coal Mine (Солнцевский угольный разрез) is an open-pit brown coal mine in southwestern Sakhalin, Russia, and the largest coal operation of the East Mining Company.

Solomon W. Golomb

Solomon W. Golomb (1932–2016) was an American mathematician and electrical engineer at the University of Southern California who founded shift-register sequence theory and created Golomb coding, Golomb rulers, and polyominoes.

Solomon's Pools

Solomon's Pools (Birak al-Marji', Burak Suliman): three stepped ancient reservoirs southwest of Bethlehem, Palestine, heart of an aqueduct system supplying Jerusalem for about 2,000 years; oldest parts late 1st century BC, Lower Pool Mamluk or Roman.

Solomon's Temple (בית המקדש הראשון)

Solomon's Temple, also called the First Temple, was the temple in Jerusalem described in the Hebrew Bible as built by King Solomon and destroyed by the Babylonians in 587/6 BCE.

Soltec

Soltec is a Spanish manufacturer of solar trackers, the motorized structures that rotate photovoltaic panels to follow the sun, founded in 2004 and headquartered in Molina de Segura, Murcia.

Soluble boron

Soluble boron, called chemical shim or a soluble poison, is boric acid dissolved in a pressurized water reactor's coolant to absorb neutrons and control core reactivity, reducing reliance on control rods.

Solution blow spinning

Solution blow spinning, also called solution blowing or air jet spinning, is a fiber fabrication method that uses pressurized gas to draw polymer solutions into micro- and nanoscale fibers.

Solution casting

Solution casting is a film-fabrication method where a polymer dissolved in a volatile solvent is spread onto a substrate and dried, leaving a solid thin film or membrane.

Solution heat treatment

Solution heat treatment is a heat treatment that heats an alloy to dissolve phases into solid solution, then rapidly cools it to leave a supersaturated structure.

Solution precursor plasma spray

Solution precursor plasma spray (SPPS) is a thermal spray coating method that injects a liquid chemical solution into a plasma jet, producing fine-grained, porous ceramic coatings.

Solution processing of perovskite solar cells

Solution processing of perovskite solar cells is the fabrication of perovskite films by depositing dissolved precursors and crystallizing them at low temperature, enabling printing and roll-to-roll production.

Solution-processed oxide thin-film transistor

A solution-processed oxide transistor is a thin-film transistor whose metal oxide channel is deposited from liquid precursors by coating or printing rather than vacuum deposition.

SOLV Energy

SOLV Energy is a San Diego-based company providing engineering, procurement, and construction and operations services for utility-scale solar and battery storage projects across the United States.

Solvay

Solvay is a Belgian chemical company in Brussels, founded in 1863 by Ernest Solvay and his brother Alfred; after spinning off Syensqo in 2023 it focuses on soda ash, peroxides, and silica.

Solveig field

Solveig is an oil field in the Norwegian sector of the North Sea on the Utsira High, discovered in 2013, producing since 2021, and operated by Aker BP.

Solvent casting

Solvent casting is a polymer processing technique that makes thin plastic films by evaporating solvent from a spread polymer solution, long used for photographic film.

Solvent dewaxing

Solvent dewaxing is a petroleum refining process that removes wax from lubricating oil stocks by solvent dilution, chilling, and filtration, giving the oil low-temperature fluidity and yielding slack wax.

Solvent engineering for perovskite films

Solvent engineering for perovskite films controls how thin films crystallize by choosing solvents and an antisolvent, such as toluene, during spin coating; it underpins most high-efficiency perovskite solar cells.

Solvent Refined Coal process

The Solvent Refined Coal (SRC) process is a US direct coal liquefaction method, developed from the 1960s to the 1980s, yielding a low-sulfur, low-ash fuel.

Solvent-in-salt electrolyte

A solvent-in-salt (SIS) electrolyte is a battery electrolyte in which salt outnumbers solvent, so anions enter the cation's solvation sheath; the aqueous variant is water-in-salt.

Solyndra

Solyndra was a Fremont, California manufacturer of cylindrical CIGS thin-film solar panels, the first recipient of a $535 million DOE loan guarantee before its 2011 bankruptcy.

Soma Port Gas power station

Soma Port Gas power station, also called the Fukushima Natural Gas Power Plant, is a 1,180 MW LNG-fueled gas power station at Soma Port in Fukushima Prefecture, Japan, opened in 2020.

Soma Port LNG Terminal

Soma Port LNG Terminal, also called the Soma LNG Terminal (相馬LNG基地), is an LNG import and regasification terminal at Soma Port in Fukushima Prefecture, Japan, operated by JAPEX.
