Triops, tadpole shrimps, is a genus of notostracan branchiopod crustaceans of temporary pools worldwide; about 11 valid species, Mesozoic origin, dormant eggs, and a debated 'living fossil' status.
Triose phosphate-isomerase deficiency
Triosephosphate isomerase deficiency (TPI deficiency, TPID) is an ultra-rare autosomal recessive glycolytic enzymopathy caused by TPI1 mutations, mostly E105D, causing hemolytic anemia, progressive neuromuscular degeneration, and childhood death.
Triosephosphate isomerase
Triosephosphate isomerase (TPI, TIM, EC 5.3.1.1) is an essential homodimeric glycolytic enzyme interconverting DHAP and glyceraldehyde-3-phosphate, namesake of the TIM barrel fold, a diffusion-limited near-perfect catalyst, and the target of TPI deficiency.

Trioxymethylen
Trioxymethylen (1,3,5-trioxane, CAS 110-88-3) is the cyclic trimer of formaldehyde, C3H6O3; a former fungicide and disinfectant, not approved as an EU pesticide active substance since Regulation 2076/2002, used in organic synthesis and as fuel.
Trioza erytreae
Trioza erytreae, the African citrus psyllid, is a sap-sucking insect of the family Triozidae that feeds on citrus and is one of two known vectors of citrus greening disease (huanglongbing), having invaded mainland Europe in 2014.

TRIP steel
TRIP steel, or transformation-induced plasticity steel, is an advanced high-strength steel in which retained austenite transforms to martensite during deformation, raising strength and ductility together; it is used mainly in automotive body structures.
TRIP-maraging steels via additive manufacturing
TRIP-maraging steels via additive manufacturing are 3D-printed steels combining the TRIP effect, deformation-induced transformation of retained austenite to martensite, with maraging age hardening, used for dies, molds, and tooling.
