Interfacial water layering
Interfacial water layering is the organization of water molecules into discrete density layers parallel to a surface, seen as oscillating density peaks within about 1 to 2 nm.
Interfacial water structure in electrocatalysis
Interfacial water structure in electrocatalysis is the molecular orientation and hydrogen bonding of water adjacent to an electrode, which governs proton transfer and reaction rates, including hydrogen evolution and carbon dioxide reduction.
Interfaith dialogue
Interfaith dialogue, also called interreligious dialogue, is organized engagement between different religions for understanding, cooperation, and peacebuilding. Key markers: 1893 Parliament of Religions, Nostra Aetate (1965), World Interfaith Harmony Week, and thin evaluation evidence.
Interfaith marriage
Interfaith marriage, also called religious intermarriage or mixed marriage, is marriage between partners of different religions; about 26% of U.S. marriages are interfaith, with Islamic and Catholic canon rules and legal restrictions in some countries.
Interfaith marriage in Christianity
Interfaith marriage in Christianity: marriage between Christians of different traditions or between a Christian and a non-Christian; governed by Catholic canon law (mixed marriage, disparity of cult), Orthodox Trullo canon 72, and rising U.S. intermarriage rates.
Interfaith marriage in Islam
Interfaith marriage in Islam covers marriages between Muslims and non-Muslims, governed by Quran 2:221, 5:5, and 60:10. Sunni law permits men to marry Jewish or Christian women but bars the reverse for women; Shia law is stricter, and Indonesia, Malaysia, and Brunei codify the rules differently.
Interfaith marriage in Judaism
Interfaith marriage in Judaism is marriage between a Jew and a non-Jew, forbidden under halakha but common among non-Orthodox American Jews. Key facts: 61% of recent U.S. Jewish marriages are interfaith, 2% among the Orthodox; Reform rabbis may officiate, Conservative rabbis are barred.
Interfascial plane block
An interfascial plane block is a regional anesthesia technique that injects local anesthetic between fascial layers to numb nerves, used in abdominal, breast, and thoracic surgery.
Interference alignment
Interference alignment is a wireless precoding technique where coordinated transmitters collapse all interference into a minimal subspace, achieving K/2 degrees of freedom and sum rates that grow linearly with network size.
Interference filter
An interference filter, also called a dichroic or thin-film filter, is an optical filter that transmits chosen wavelengths via interference between reflections from dozens of alternating dielectric layers, used in fluorescence microscopy and LIDAR.
Interference lithography
Interference lithography, also called holographic or laser interference lithography, is a maskless fabrication method in which overlapping coherent laser beams pattern periodic nanostructures in photoresist.
Interference microscopy
Interference microscopy is an optical technique that measures the optical path difference between a specimen beam and a reference beam, converting it into surface height, optical thickness, or refractive-index maps.
Interference neutralization
Interference neutralization (IN) is a wireless interference management technique in which relays apply linear processing so interfering signals cancel over the air while desired signals remain decodable.
Interference of light
Interference of light is the redistribution of optical energy when two or more light waves superpose, producing bright and dark fringes where waves arrive in or out of step.
Interference temperature
Interference temperature is a radio-spectrum metric proposed by the FCC that expresses average undesired radio-frequency power arriving at a receiver as an equivalent temperature in kelvin.
Interferometric imaging
Interferometric imaging reconstructs an image of a distant or large object by coherently combining signals from separated antennas or apertures, a technique central to radio astronomy and used in InSAR.
Interferometric microscopy
Interferometric microscopy is a noncontact optical technique that measures surface topography and phase variations by interference, delivering full-field 3D maps with sub-nanometer resolution for industrial metrology and biological imaging.
Interferometric particle imaging
Interferometric particle imaging (IPI), also called interferometric laser imaging for droplet sizing (ILIDS), is an optical diagnostic measuring droplet size, position, and velocity from interference fringes.
Interferometric reflectometry
Interferometric reflectometry (GNSS-IR) is a ground-based remote sensing technique that uses interference between direct and surface-reflected GNSS signals to measure sea level, soil moisture, snow depth, and vegetation water content.
Interferometric scattering microscopy
Interferometric scattering microscopy, also known as interferometric scattering or iSCAT, is a label-free optical technique detecting single molecules and nanoparticles, introduced in 2004 and used for mass photometry and high-speed tracking.
Interferometric synthetic-aperture radar
Interferometric synthetic-aperture radar (InSAR) is a remote-sensing method comparing radar images from repeated satellite passes to map millimeter-scale ground deformation from earthquakes, volcanoes, and subsidence.
Interferometric visibility
Interferometric visibility, also called fringe visibility or fringe contrast, is a dimensionless measure of the contrast of an interference pattern, ranging from 0 to 1.
Interferometry
Interferometry is a family of measurement techniques that extract information from the superposition of two or more waves, most often light, and ranks among the most sensitive forms of measurement available.
Interferon
Interferon (IFN), a group of signaling proteins described by Alick Isaacs and Jean Lindenmann in 1957, are cytokines secreted in response to viruses to inhibit cell growth.
Interferon alfa
Interferon alfa (IFN-α, interferon alpha) is a type I interferon cytokine; recombinant alfa-2a and alfa-2b, FDA-approved since 1986, treat hepatitis B and C, myeloproliferative neoplasms, and cancers.
Interferon alfa-2a
Interferon alfa-2a is a recombinant human type I interferon produced in E. coli, marketed by Hoffmann-La Roche as Roferon-A; its PEGylated form, Pegasys, remains in clinical use.
Interferon alfa-2b
Interferon alfa-2b (Intron A) is a recombinant form of human alpha interferon, approved in 1986 for hairy cell leukemia and used to treat hepatitis B and C and several cancers.
Interferon alfacon-1
Interferon alfacon-1 (consensus interferon, Infergen) is a synthetic 166-amino-acid type I interferon alpha for chronic hepatitis C, FDA-approved 1997, withdrawn in the EU in 2006.
Interferon beta
Interferon beta (IFN-β), type I interferon; recombinant products Betaseron, Avonex, Rebif, Plegridy; first disease-modifying therapy for relapsing-remitting multiple sclerosis, FDA approved 1993, reducing relapses 15-36%.
Interferon beta-1a
Interferon beta-1a, sold as Avonex, Rebif, and pegylated Plegridy, is a glycosylated type I interferon drug for relapsing multiple sclerosis; FDA-approved from 1996, it reduces relapses about 30% versus placebo.
