BOND (venture capital firm)
BOND, or Bond Capital, is a San Francisco growth-stage venture capital firm co-founded by Mary Meeker in 2018 as a spinout of Kleiner Perkins's digital growth fund.
Bond albedo
The Bond albedo, also called the spherical albedo, is the fraction of total incoming radiation, at all wavelengths and angles, that a body reflects back into space.
Bond angle
A bond angle is the angle between two chemical bonds sharing a common atom, one of the three internal coordinates that fix a molecule's geometry.
Bond convexity
Bond convexity measures the curvature of the relationship between a bond's price and its yield, capturing the second-order, non-linear price change that duration, a first-order measure, misses.
Bond credit rating
A bond credit rating, also called a bond rating, is a rating agency's opinion of a debt issuer's relative credit risk, expressed on letter scales from AAA down to D.
Bond events
Bond events are proposed quasi-periodic cold episodes during the Holocene, identified by Gerard Bond and colleagues in North Atlantic sediments as pulses of ice-rafted debris.
Bond girl
Bond girl: female love-interest or significant supporting character in James Bond novels, films, and games. First film example Honey Ryder (Ursula Andress, Dr. No, 1962); over 75 characters; typologies, Craig-era reworking, and feminist criticism.
Bond graph
A bond graph is a graphical modeling method representing a physical system as bonds along which power flows between idealized elements, converting any energy-domain schematic into state-space equations.
Bond indenture
A bond indenture is the contract between a bond issuer and a trustee, acting for bondholders, that sets out bond terms, covenants, events of default, and remedies.
Bond lease
Bond lease covers two instruments: a lease bond, a surety bond guaranteeing a tenant's lease performance in place of a cash deposit (premiums 1–5% yearly), and the bond lease of credit tenant finance, an absolute net lease treated as a bond for Schedule D reporting.
Bond length
Bond length, also called bond distance, is the distance between the atomic centers involved in a chemical bond, commonly reported in picometers or ångströms; higher bond order means shorter bonds.
Bond localization in annulenes
Bond localization in annulenes is the tendency of carbon–carbon bonds in cyclic conjugated polyenes to alternate between shorter double-bond-like and longer single-bond-like lengths rather than equalize as in benzene.
Bond market
The bond market, also called the debt or credit market, is where bonds are issued and traded, the world's largest securities market at over $150 trillion.
Bond number
The Bond number (Bo), also called the Eötvös number, is a dimensionless number comparing gravitational forces to surface tension forces; below 1 surface tension dominates, above 1 gravity dominates.
Bond of 1844
The Bond of 1844 was an agreement signed at Cape Coast Castle on 6 March 1844 between Britain and eight Fante chiefs, submitting serious crimes to British jurisdiction.
Bond order
Bond order is a measure of how strongly two atoms in a molecule are bonded, with single, double, and triple bonds having orders 1, 2, and 3.
Bond-dissociation energy
Bond-dissociation energy, also called bond dissociation enthalpy or bond enthalpy, is the enthalpy per mole required to break a specific bond by homolysis, forming two radicals.
Bond-order imaging with CO-functionalized atomic force microscopy
Bond-order imaging with CO-functionalized atomic force microscopy is a scanning probe technique in which a carbon monoxide-terminated tip resolves individual chemical bonds, introduced at IBM Research–Zurich in 2009.
Bondage (BDSM)
Bondage, the B in BDSM, is consensual adult restraint or restricted movement for sensory, psychological, or role-based purposes. Covers forms like shibari, safewords, Safe-Sane-Consensual norms, physical risks, history from Krafft-Ebing to Fifty Shades, and clinical guidance.
Bondage pornography
Bondage pornography: sexually explicit media centered on restraint and binding imagery within the BDSM spectrum. Also called kinbaku-related content in Japan. Defined by depiction of consensual restraint for arousal; historically a print-magazine specialty, now regulated, e.g., UK 2026 strangulation ban.
Bondage positions and methods
Bondage positions and methods are consensual restraint techniques within BDSM, using rope, cuffs, and shibari; defined by negotiation, safe words, and safety limits against nerve injury, positional asphyxia, and strangulation risks.
Bonde do Brunão
Bonde do Brunão is a 57-second funk carioca single by Bruno Mars, sung in Portuguese, first posted 7 November 2024 after his 15-show Brazil tour and officially released 18 June 2025 via The Smeezingtons/Atlantic, tied to Fortnite Festival Season 9 and parodying Bonde do Tigrão's Cerol na Mão.
Bonded leather
Bonded leather, also called reconstituted leather, is a composite of shredded leather scraps bonded with polyurethane or latex onto a backing, typically 10-20% leather fiber, used in budget furniture and book covers, prone to peeling.
Bonded particle model
The bonded particle model is a discrete element simulation method that represents rock as rigid particles joined by breakable bonds, so fracture emerges from bond breaking.
Bonded warehouse
A bonded warehouse, also called a bond store, is a customs-supervised building where imported goods are stored without payment of duty until they are withdrawn or re-exported.
Bondelswarts Rebellion
The Bondelswarts Rebellion was a May and June 1922 rising by the Bondelswarts, a Nama people of southern South West Africa, against the South African administration, put down with aircraft bombing.
Bondi accretion
Bondi accretion is the steady, spherically symmetric accretion of gas onto an isolated mass like a star or black hole, solved analytically by Hermann Bondi in 1952.
Bondi Beach
Bondi Beach, Sydney's famous one-kilometre ocean beach in Waverley, NSW, birthplace of world surf lifesaving (Bondi Surf Bathers' Life Saving Club, 1907), National Heritage listed 25 January 2008, site of the 14 December 2025 Hanukkah terror attack that killed 15.
Bondi Beach shooting
Antisemitic terrorist attack of 14 December 2025 at the Chanukah by the Sea event on Bondi Beach, Sydney, in which father and son Sajid and Naveed Akram killed 15 and wounded about 40 before police intervention.
Bondi Junction stabbings
The Bondi Junction stabbings, also known as the Sydney mall attack, were a mass stabbing at Westfield Bondi Junction in Sydney, Australia, on 13 April 2024, killing six people.
