A membrane electrode assembly (MEA) is an assembled stack of proton exchange membranes (PEM) or alkali anion exchange membrane (AAEM), catalyst and flat plate electrode used in fuel cells and elect...
Cross-metathesis of terminal olefins
An opto-electronic oscillator (OEO) is an optoelectronic circuit that produces repetitive electronic sine wave and/or modulated optical continuous wave signals. An opto-electronic oscillator is ...
In signal processing, phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities ("jitter").[1] Gen...
Neural stem cells (NSCs) are self-renewing, multipotent cells that generate the main phenotype of the nervous system. Stem cells are characterized by their capability to differentiate into multiple...
IC/Mems process
When two or more different monomers unite together to polymerize, their result is called as copolymer and its process is called copolymerization.
In enzymology, a dihydropyrimidinase (EC 3.5.2.2) is an enzyme that catalyzes the chemical reaction 5,6-dihydrouracil + H2O \rightleftharpoons 3-ureidopropanoate Thus, the two substrates of thi...
Dopants for liquid-crystal devices
The reaction is catalyzed by metal complexes. Traditional catalysts are prepared by a reaction of the metal halides with alkylation agents, for example WCl6–EtOH–EtAlCl2. The traditional, industria...

Hydro elastic pump
Microwave bonding
A Hydrogel is a network of polymer chains that are hydrophilic, sometimes found as a colloidal gel in which water is the dispersion medium. Hydrogels are highly absorbent (they can contain over 90%...
An amorphous metal (also known metallic glass or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most metals are crystalline in their solid s...
Detection of analytes in fluids
An electret microphone is a type of electrostatic induction-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.
Lithography (from Greek λίθος, lithos, "stone" and γράφειν, graphein, "to write") is a method of printing originally based on the immiscibility of oil and water.[1] Printing is from a stone (lithog...
