magnesium fluoride
A colorless, crystalline compound whose low refractive index (n = 1.38) makes it effective as a lens antireflection coating when deposited by thermal evaporation in a near vacuum. This process...
magnetic resonance spectroscopy
A method of studying the chemical and physical properties of atoms and molecules (typically living tissue and chemical samples) by exploiting the magnetic properties of their atomic nuclei when an...
mass spectrometer
A device used to measure the masses and relative concentrations of atoms and molecules. It utilizes the Lorentz force generated by external magnetic field on a moving charged particle, in which the...
mass spectrometry
An instrumental technique that utilizes the mass-to-charge ratio of charged particles as recorded from a mass spectrometer in order to determine the mass of a particle as well as the chemical makeup,...
mass spectroscope
An instrument that uses electromagnetic fields to sort out the relative masses of atoms and molecules.The same way an optical spectroscope uses a prism to separate light into its various wavelengths,...
mass spectrum
A spectrum that displays the distribution in mass or in mass-to-charge ratio of ionized atoms, molecules or molecular parts. Mass spectrums are typically recorded by instruments utilized in mass...
MBE
molecular beam epitaxy — A well-controlled thin film technique for growing films with good crystal structure in ultra high vacuum environments at very low deposition rates. MBE is also commonly used in the manufacture of semiconductor devices and solar cells.
MERA
molecular electronics for radar applications
meso form
A form of an element that cannot demonstrate optical activity as a result of dextrogyrate and levogyrate effects that are balanced contrary to each other in a structure. In essence, meso form...
metabolic imaging
Metabolic imaging refers to the visualization and quantification of metabolic processes within living organisms, tissues, or cells using various imaging techniques. It provides insights into the...
metabolite
A metabolite is any small molecule that is a product of metabolism, the chemical processes that occur within living organisms to maintain life. Metabolites can include a wide variety of molecules,...
metallorganic chemical vapor deposition
A method of growing single crystals in which atoms and molecules from gaseous organic compounds interact and form a layer on a single-crystal substrate.
metallorganic vapor phase epitaxy

metallorganic chemical vapor deposition
A method of growing single crystals in which atoms and molecules from gaseous organic compounds interact and form a layer on a single-crystal substrate.
metamerism
In colorimetry, the phenomenon in which spectrally different radiations produce the same color sensation for a given observer. In chemistry, the chemical property of two elements or molecules sharing...
microbubble resonator
A microbubble resonator is a device used in photonics and optical physics for the precise manipulation of light waves. It consists of a micro-sized, gas-filled spherical cavity (the "microbubble")...
microheterogeneous systems
Extremely small organic and inorganic systems of molecules within a substance. In general, systems are colloidal size in spite of the large number of molecules. Photochemistry and optical...
microRNA
MicroRNAs (miRNAs) are a class of small, single-stranded RNA molecules, typically consisting of about 19 to 24 nucleotides, that play important roles in the regulation of gene expression in cells....
microscopy
Microscopy is a scientific technique that involves the use of microscopes to observe and study objects that are too small to be seen with the naked eye. Microscopes are instruments that magnify and...
mid-infrared camera
A mid-infrared camera is a type of imaging device designed to capture images in the mid-infrared (mid-IR) spectral range, typically spanning wavelengths from approximately 3 to 12 µm. This...
MIRT
molecular infrared track
mixed crystal
A homogeneous solid solution with crystal lattice sites occupied, at random, by the molecules or ions of two or more separate compounds
molecular beam epitaxy
->
epitaxy
A well controlled thin films technique for growing films with good crystal structure in ultra high vacuum environments at very low deposition rates. Epitaxy methods are well known for the growing of...
molecular modeling
A method of predicting the nonlinear optical effects exhibited by different molecules without synthesizing the molecules themselves.
molecular motor
A molecular motor refers to a nano-sized device composed of organic molecules or other small-scale components that can convert light energy into mechanical motion at the molecular level. These...
molecular spectroscopy
Spectrum analysis concerned with the spectra formed by transitions in molecules.
MOMBE
metallorganic molecular beam epitaxy
monomer
A molecule that has the ability to chemically combine with other molecules to form a polymer, hence being capable of being polymerized. See polymer; polymerization
multiline laser system
A multiline laser system refers to a type of laser that is capable of emitting multiple discrete wavelengths or spectral lines simultaneously. Unlike single-line lasers, which produce radiation at a...
multiphoton process
A process involving the interaction (absorption, emission or both) of two or more photons with a molecular entity.
multispectral imaging
Multispectral imaging is a technique that involves capturing and analyzing images at multiple discrete spectral bands within the electromagnetic spectrum. Unlike hyperspectral imaging, which acquires...
