Disinfectant
A disinfectant, or disinfecting agent, is a substance that destroys or irreversibly inactivates bacteria, fungi, and viruses on inanimate surfaces, though not always bacterial spores.
Disinfection by-products
Disinfection by-products (DBPs) are contaminants formed when disinfectants such as chlorine react with organic matter in drinking water; the US EPA limits trihalomethanes and haloacetic acids.
Disinflation
Disinflation is a decrease in the rate of inflation, so prices keep rising but more slowly, unlike deflation, a sustained fall in prices that can raise unemployment.
Disinformation
Disinformation is deliberately false or misleading information spread to deceive or harm, distinguished from misinformation by intent. Traced to Soviet dezinformatsiya and active measures; now studied via detection methods and countered by UNESCO and EU codes.

Disinhibited social engagement disorder
Disinhibited social engagement disorder (DSED), formerly disinhibited RAD or ICD-10 disinhibited attachment disorder, is a childhood disorder of indiscriminate sociability toward strangers after severe neglect, diagnosable from 9 months, distinct from autism and RAD.
Disinhibition
Disinhibition, also called behavioral disinhibition or the disinhibition versus constraint trait, is reduced restraint over impulses and emotions, seen as a neurological state after frontal brain injury, alcohol, or drugs, and as a personality trait linked to externalizing psychopathology and ICD-11 trait domains.
Disinhibition in dementia
Disinhibition in dementia (ICD-11 6D86.5) is a neuropsychiatric symptom of impaired restraint, impulsivity, and poor risk assessment, common in bvFTD and Alzheimer's disease, managed with pain treatment and nonpharmacological care.
Disintegrating exoplanet
A disintegrating exoplanet is a small rocky planet orbiting so close to its star that heat vaporizes its surface into dust, forming a comet-like tail that dims the star.
Disintegration (The Cure album)
Disintegration is The Cure's eighth studio album, released 2 May 1989 on Fiction Records, produced by Robert Smith and David M. Allen. The dark gothic rock record sold over 3 million copies behind "Lovesong" (US no. 2) and "Lullaby" (UK no. 5).

The disintegration of Kievan Rus' was the breakup of the East Slavic polity centered on Kyiv into hereditary principalities after 1054, ending with the Mongol conquest of 1240.
Disintegration of the Bahmani Sultanate
The disintegration of the Bahmani Sultanate was its breakup into five Deccan sultanates, including Bijapur, Ahmadnagar, Berar, Bidar, and Golconda, ending the dynasty in 1527.
Disintegrin domain
Disintegrin domain: 40–100 aa cysteine-rich integrin-binding module from viper venom PII-SVMPs, RGD or KGD motif; basis of antiplatelet drugs tirofiban and eptifibatide.
Disitamab vedotin
Disitamab vedotin, sold as Aidexi and code-named RC48, is an antibody–drug conjugate targeting HER2, developed by RemeGen and first approved in China in 2021 for gastric cancer.
Disiz
Disiz, also Disiz la Peste and Disiz Peter Punk, is the stage name of Sérigne M'Baye Gueye, a French rapper and singer born in 1978 in Amiens.
Disjoining pressure
Disjoining pressure is the pressure difference across a thin liquid film confined between two surfaces, arising from intermolecular forces, introduced by Derjaguin and Obuchov in 1936.
Disjoint sets
Disjoint sets, also called mutually exclusive sets, are sets that share no elements, so their intersection is empty; the concept underlies partitions and counting rules.
Disjoint-set data structure
The disjoint-set data structure, also called union-find, maintains a partition of elements into disjoint subsets; with union by rank and path compression, each operation runs in effectively constant amortized time.
Disjointed
Disjointed is a 2017-2018 Netflix multicam sitcom co-created by Chuck Lorre and David Javerbaum, starring Kathy Bates as dispensary owner Ruth Whitefeather Feldman; 20 episodes, canceled after one two-part season, 19% on Rotten Tomatoes.
Disk Cleanup
Disk Cleanup is a built-in Microsoft Windows utility, launched as Cleanmgr.exe, that frees hard drive space by deleting temporary files, Recycle Bin contents, and superseded Windows Update components.
Disk cloning
Disk cloning, also known as disk ghosting, is the process of making a complete block-level copy of a disk drive or partition for use in place of the original.
Disk encryption theory
As a branch of cryptography, Disk encryption theory studies encryptable storage sectors under the constraint that ciphertext must match plaintext size, shaping FDE modes and security definitions.
Disk formatting
Disk formatting, also called disk format, is the process of preparing a storage device or partition for use by creating a file system, erasing existing data.
Disk image
A disk image is a byte-by-byte copy of a storage device, such as a hard drive or optical disc, stored as one file for recovery or cloning.
Disk laser
A disk laser, typically thin-disk, is a diode-pumped solid-state laser using a thin crystal on a heat sink, enabling high power, efficiency, and beam quality.
Disk operating system
A disk operating system (DOS) is an operating system that loads from and manages files on magnetic disks, best known through Microsoft's MS-DOS and IBM's PC-DOS.
Disk partitioning
Disk partitioning is the division of a hard drive or SSD into one or more logical disks called partitions, recorded in a partition table, using MBR or GPT formats.
Disk read-and-write head
The disk read-and-write head, also called the read-write head, is the electromagnetic component of a hard disk drive that writes and reads data on spinning platters.
Disk resonator gyroscope
A disk resonator gyroscope (DRG) is a MEMS Coriolis vibratory gyroscope in which a vibrating flat disk or set of concentric rings senses rotation, first developed by Boeing.
Disk sector
A disk sector is the smallest addressable unit of storage on a disk drive, historically 512 bytes and now typically 4,096 bytes under the Advanced Format standard.
