Boron trioxide

Boron trioxide, also called boric oxide or boric anhydride, is a white, hygroscopic solid (B₂O₃) that reacts with water to form boric acid and serves as the main boron source for borosilicate glass.

Boron vacancy center in hexagonal boron nitride

The boron vacancy center in hexagonal boron nitride (VB−) is a missing-boron point defect whose spin can be controlled optically at room temperature, used for nanoscale quantum sensing.

Boron-10

Boron-10 is a stable isotope, about 20 percent of natural boron, whose strong neutron absorption makes it key to reactor control rods and boron neutron capture therapy.

Boron-based radical chemistry with photoredox

Boron-based radical chemistry with photoredox is a branch of synthetic organic chemistry in which visible light generates boryl or carbon radicals from organoboron compounds under mild conditions.

Boron-centered radical anion chemistry

A boron-centered radical anion is a reduced, paramagnetic boron species with the unpaired electron largely on boron, first reported in 1924 and used as sensors, synthesis reagents, and polymerization initiators.

Boron-doped diamond electrode

A boron-doped diamond electrode is a working electrode made of boron-doped synthetic diamond, introduced in 1992 and used in electroanalysis, wastewater treatment, and biomedical sensing.

Boronate ester

A boronate ester is the condensation product of a boronic acid with a diol, valued for reversible hydrolysis in water and as a protected boronic acid form.

Boronate homologation

Boronate homologation is a family of reactions extending a boronic ester's carbon chain by one or more atoms, best known as the Matteson homologation, first reported in 1963.

Boronate hydrogel

A boronate hydrogel is a hydrated polymer network cross-linked by reversible boronate ester bonds between boronic acids and diols, making it self-healing, injectable, and responsive to pH, sugars, and ROS.

Boronic acid

A boronic acid is an organoboron compound of structure RB(OH)2, first isolated in 1860 by Frankland, known for reversibly binding cis-diols and serving as the standard reagents in Suzuki–Miyaura cross-coupling.

Boronic ester dynamic covalent networks

Boronic ester dynamic covalent networks are crosslinked polymer materials whose strands connect through reversible boronic ester bonds, yielding vitrimers and hydrogels that self-heal, reprocess, and respond to pH, redox, and sugars.

Boroondara

City of Boroondara, a Melbourne local government area formed 22 June 1994 from Camberwell, Kew, and Hawthorn; 167,900 residents (2021), $280 million 2025-26 budget, Camberwell council offices.

Borophene

Borophene is a two-dimensional crystalline allotrope of boron, a single-atomic-layer sheet first synthesized in 2015 on a silver substrate as the boron analog of graphene.

Bororo

Bororo (Boe): indigenous people of Mato Grosso, Brazil, speaking a Macro-Jê language; matrilineal, eight clans, circular villages around a men's house; studied by Lévi-Strauss.

Bororo oral literature

Bororo oral literature is the spoken and sung verbal art, called bakaru, of the Bororo (Boe) people, an indigenous people of Mato Grosso, Brazil, closely tied to ritual life.

Borosilicate glass

Borosilicate glass, a brand of which is Kimax, is a durable glass invented by Otto Schott in 1887, valued for resisting heat and chemicals in labware and cookware.

Borospherene

Borospherene is a hollow, cage-like cluster of boron atoms first observed as the B40 anion in 2014. Neutral B40 is regarded as the first pure boron buckyball.

Borotbists

The Borotbists (боротьбісти) were the left faction of the Ukrainian Party of Socialist Revolutionaries that broke away in May 1918, adopting a communist but independentist platform.

Borouge

Borouge is an Abu Dhabi-based producer of polyethylene and polypropylene, founded in 1998 as a partnership between ADNOC and Borealis, with a 5-million-tonne complex at Ruwais.

Borough

Borough: administrative division from Old English burh, a fortified town. Covers UK borough status under LGA 1972 s.245, London's 32 boroughs, 36 metropolitan boroughs, NYC's five boroughs, Pennsylvania's 955 boroughs, and Alaska's 16 county-equivalent boroughs.

Borough (New Jersey)

Borough (New Jersey): the most common of New Jersey's five municipal forms, used by over 200 of 564 municipalities. Weak-mayor, six-member council government dating to the 1878 Borough Act; the 1894 school-tax law drove the boroughitis wave.

Borough Market
