Bismuth-doped fiber
Bismuth-doped fiber is an optical fiber with a bismuth-doped core that emits broadband near-infrared luminescence, serving as a gain medium for lasers and amplifiers in the O-, E-, and S-bands.
Bismuth-doped fiber amplifier
A bismuth-doped fiber amplifier (BDFA) is an optical fiber amplifier with a bismuth-doped core, used to amplify near-infrared light in O- and E-band telecom regions where erbium provides no gain.
Bismuthene
Bismuthene is a one-atom-thick two-dimensional form of bismuth, grown as a honeycomb monolayer on silicon carbide and the leading candidate for a room-temperature quantum spin Hall insulator.
Bison
Bison is a genus of large wild cattle with two surviving species, the American bison (Bison bison, often called buffalo) and the European wisent (Bison bonasus), known for their shoulder humps, Pleistocene origins, near-extinction, and conservation recovery.
Bison compound

Bison Dele
Bison Dele, born Brian Carson Williams (1969), NBA center-forward drafted 10th in 1991, 1997 Bulls champion, retired in 1999 leaving $36 million; vanished at sea in 2002 with Serena Karlan and Bertrand Saldo, a murder case implicating brother Miles Dabord.
Bison hunting
Bison hunting: 13,000 years of communal Indigenous hunts (jumps, pounds) on the Great Plains, Métis horseback hunts, the 1870s–1880s hide-trade collapse from tens of millions to a few hundred, and modern Tribal restoration hunts.
Bison Kaalamaadan (பைசன் காலமாடன்)
Bison Kaalamaadan (பைசன் காலமாடன்), also released as Bison, is a 2025 Tamil sports drama by Mari Selvaraj based on kabaddi player Manathi Ganesan, starring Dhruv Vikram as Kittan, released 17 October 2025.
Bison Ventures
Bison Ventures is a venture capital firm founded in 2022 by Tom Biegala and Ben Hemani, both formerly of the Gates Foundation's investment office, investing in early-stage deep technology companies.
Bisoprolol
Bisoprolol, a beta1-selective cardioselective beta-blocker (bisoprolol fumarate), treats hypertension and chronic heart failure; CIBIS-II showed mortality reduction (HR 0.66), making it one of three evidence-based heart failure beta-blockers.
Bisotun
Bisotun, also spelled Behistun, is an archaeological site in Kermanshah province, western Iran, whose key monument is Darius I's trilingual cuneiform inscription of 521 BC, a key to deciphering cuneiform.
Bispecific antibody therapy
Bispecific antibody therapy is a cancer and immune-disorder treatment using engineered antibodies that bind two antigens at once, often directing T cells to kill tumor cells.
Bispectral index monitoring
Bispectral index monitoring is a processed-EEG technique that turns forehead readings into a 0 to 100 score of hypnotic depth, FDA-cleared in 1996 and widely used to guide anesthesia.
Bisphenol A
Bisphenol A (BPA) is a synthetic organic compound used to make polycarbonate plastics and epoxy resins, including food containers and can liners, and is classified as an endocrine-disrupting chemical.
Bisphenol A diglycidyl ether
Bisphenol A diglycidyl ether, also known as diglycidyl ether of bisphenol A, is an organic compound made from bisphenol A and epichlorohydrin that forms most epoxy resins.
Bisphenol AF
Bisphenol AF (BPAF) is an organofluorine bisphenol in which the methyl hydrogens of bisphenol A are replaced by fluorine. Introduced as a curative in 1970, it crosslinks most commercial fluoroelastomers and shows potent estrogenic activity.
Bisphenol F
Bisphenol F (BPF), or bis(4-hydroxyphenyl)methane, is a bisphenol compound used mainly in epoxy and polycarbonate resins and adopted as a common substitute for bisphenol A (BPA) as restrictions on BPA tightened.
Bisphenol S
Bisphenol S (BPS) is an organic compound used as a polymer monomer and the color developer in thermal paper, best known as the main replacement for bisphenol A in BPA-free products.
Bisphosphonate
Bisphosphonates (diphosphonates) are P–C–P bone-seeking drugs inhibiting osteoclasts; first-line for osteoporosis, Paget's disease, and metastatic bone disease. Key agents: alendronate, risedronate, zoledronate; first clinical use etidronate, 1968.
Bispyribac
Bispyribac (bispyribac-sodium, Nominee) is a pyrimidinyl carboxy ALS-inhibiting herbicide developed by Kumiai Chemical for post-emergence weed control in rice at 20-45 g/ha; EU approval expired in 2022, and P450-mediated resistance is documented in Echinochloa and Cyperus.
BiSS interface
BiSS interface is an open synchronous serial standard for connecting sensors and absolute encoders to industrial controllers and servo drives, introduced by iC-Haus in 2002.
Bissandougou
Bissandougou, also spelled Bisandugu or Bissandugu, was the capital of the Wassoulou Empire built by Samori Touré in eastern Guinea, and gave its name to his 1887 treaty with France.
Bissau
Bissau is the capital and largest city of Guinea-Bissau, a port on the Geba estuary. Founded 1692, colonial capital from 1942, about 502,711 people in the 2026 census, roughly a quarter of the national population.
Bissell
Bissell is an American floor-care and home-cleaning appliance manufacturer headquartered in Walker, Michigan. Founded in 1876, it is best known for carpet sweepers, vacuums, and carpet deep cleaners.
Bistability
Bistability is the property of a dynamical system in which two stable steady states coexist under identical conditions, separated by an unstable state, as in chemical reactors and biochemical networks.
Bistable mechanical metamaterial
A bistable mechanical metamaterial is an engineered material whose unit cells have two stable configurations that persist without force and switch reversibly by snap-through, enabling energy absorption and mechanical memory.
Bistable origami structure
A bistable origami structure is a folded mechanical system with two stable states, so it holds a deployed shape without power and snaps between them when pushed over an energy barrier.
Bistable shock-absorbing metamaterials
Bistable shock-absorbing metamaterials are architected materials built from unit cells with two stable states that absorb impact by snapping between them, storing energy instead of transmitting it, and remaining reusable.
Bistatic radar
Bistatic radar is a radar configuration in which the transmitting and receiving antennas are at different locations, used for air surveillance, ocean remote sensing, and planetary science.
Bistatic SAR
Bistatic SAR, also known as BiSAR, is a form of synthetic aperture radar with transmitting and receiving antennas on different platforms, illuminating and imaging from separate locations.
