SOLPS-ITER is a code suite, launched in 2015 under the ITER Organization, for simulating the plasma edge in tokamaks, coupling the B2.5 plasma solver with the EIRENE neutral transport code.
Solriamfetol
Solriamfetol (Sunosi) is a once-daily oral dopamine and norepinephrine reuptake inhibitor approved in 2019 in the US and EU to improve wakefulness in adults with excessive daytime sleepiness from narcolepsy or obstructive sleep apnea; doses 37.5-150 mg, Schedule IV, main risk dose-related blood pressure increases.
Solsbury Hill
Solsbury Hill (Little Solsbury Hill) is a 188-191 m hill above Batheaston, northeast Bath, Somerset, crowned by a 7.9 ha univallate Iron Age hillfort occupied c. 300-100 BC, a National Trust scheduled monument, and the namesake of Peter Gabriel's 1977 song.
Solsbury Hill (song)
Solsbury Hill (1977) is Peter Gabriel's debut solo single, written after leaving Genesis; 7/4 meter, UK No. 13, produced by Bob Ezrin, later covered by Erasure.
Sólstafir
Sólstafir, Icelandic for "crepuscular rays", is an Icelandic post-metal band formed in Reykjavík in 1995, which has released eight studio albums and signed with Century Media Records in 2024.
Solstice
A solstice is one of the two yearly moments when the Sun reaches its greatest distance north or south of the celestial equator, around June 21 and December 21.
Solstice Oncology
Solstice Oncology, also known as Lumara Therapeutics, is a Boston-based clinical-stage immuno-oncology company founded in 2026, developing the anti-CTLA-4 antibody porustobart licensed from Harbour BioMed.
Soltaniyeh
Soltaniyeh (Sultaniyye), Zanjan province, Iran: 14th-century Ilkhanid capital, home to the Mausoleum of Oljaytu (1302–12), a 50 m turquoise double-shell dome, UNESCO World Heritage site since 2005.
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.
Solti-síkság
Solti-síkság (Solt Plain, also Csepel-Solt-Bajaisíkság, Kalocsai-síkság) is a Hungarian geographical microregion (code 1.1.22) on the Danube's left bank in Bács-Kiskun County, a 93 m floodplain with saline soils and 99.2 D-e-Meter cropland quality.
Solubility
Solubility, also known as saturation concentration, is the proportion of a designated solute that dissolves in a solvent, ranging from essentially zero for insoluble substances to infinity for miscible ones.
Solubility product
The solubility product, Ksp, is the equilibrium constant for a slightly soluble ionic solid dissolving into its ions; precipitation occurs when the ion product Q exceeds it.
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.
Soluble reactive phosphorus
Soluble reactive phosphorus (SRP), also called molybdate reactive phosphorus or dissolved reactive phosphorus, is a filtered phosphorus measurement used in limnology as an estimate of phosphate available to algae.
Solugen
Solugen is a Houston, Texas-based sustainable-chemicals startup founded in 2016 by Gaurab Chakrabarti and Sean Hunt, making chemicals from plant sugars with engineered enzymes at its Bioforge plants.
Soluntum
Soluntum (Soloeis, Solous, modern Solunto) was a Phoenician colony on the northern coast of Sicily, 20 km east of Palermo, refounded in the mid-4th century BC and surrendered to Rome in 254 BC.
Solute stabilization of nanocrystalline metals
Solute stabilization of nanocrystalline metals is an alloy-design strategy in which solute atoms segregate to grain boundaries to keep grains smaller than about 100 nm from coarsening when heated.
Solution (band)
Solution was a Dutch progressive and jazz rock band from Groningen, active from 1970 to 1983, that recorded two albums for Elton John's Rocket label.
Solution (chemistry)
A solution in chemistry is a homogeneous mixture in which a solvent dissolves one or more solutes, existing in any combination of gas, liquid, and solid states.
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 calorimetry
Solution calorimetry is the experimental measurement of the heat absorbed or released when a substance dissolves in a solvent or reacts in solution, yielding enthalpies of solution, reaction, and formation.
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 combustion synthesis
Solution combustion synthesis is a chemistry method that prepares oxide, metal, and alloy powders by igniting a metal salt and organic fuel solution, using its own exothermic heat.
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 polymerization
Solution polymerization is a polymerization method in which monomer and initiator are dissolved in a solvent that absorbs reaction heat and lowers viscosity, used for tire rubbers and coatings.
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 scattering
Solution scattering is a structural characterization method using small-angle X-ray or neutron scattering (SAXS, SANS) to determine the size, shape, and assembly of macromolecules in near-native solution, without crystallization.
Solution styrene-butadiene rubber
Solution styrene-butadiene rubber (SSBR), also called solution-polymerized SBR, is a synthetic rubber copolymerized from styrene and butadiene in an organic solvent, used mainly in tire treads.
Solution-enhanced dispersion by supercritical fluids
Solution-enhanced dispersion by supercritical fluids (SEDS) is a supercritical antisolvent technique, introduced in 1999, that sprays a drug solution with supercritical carbon dioxide through a coaxial nozzle to form fine particles.
