In taxonomy, Thermococcus is a genus of thermophilic Archaea in the family the Thermococcaceae. Members of the genus Thermococcus are typically irregularly shaped coccoid species, ranging in size from 0.6 to 2.0 mm in diameter. Some species of Thermococcus are immobile, and some species have motility, using flagella as their main mode of movement. These […]

Jene A. Golovchenko (1946 - November 13, 2018) was an American physicist. He was born in 1946, and received his PhD in physics in 1972, from Rensselaer Polytechnic Institute. He completed three sets of postdoctoral studies at Aarhus University and spent several years in industry as a Distinguished Member of the Technical Staff at Bell […]

Multi-spectral optoacoustic tomography (MSOT), also known as functional photoacoustic tomography (fPAT), is an imaging technology that generates high-resolution optical images in scattering media, including biological tissues. MSOT illuminates tissue with light of transient energy, typically light pulses lasting 1-100 nanoseconds. The tissue absorbs the light pulses, and as a result undergoes thermo-elastic expansion, a phenomenon […]

Polylactic acid, also known as poly(lactic acid) or polylactide (PLA), is a thermoplastic polyester with backbone formula (C3H4O2)n or [-C(CH3)HC(=O)O-]n, formally obtained by condensation of lactic acid C(CH3)(OH)HCOOH with loss of water (hence its name). It can also be prepared by ring-opening polymerization of lactide [-C(CH3)HC(=O)O-]2, the cyclic dimer of the basic repeating unit. PLA […]

A field emitter array (FEA) is a particular form of large-area field electron source. FEAs are prepared on a silicon substrate by lithographic techniques similar to those used in the fabrication of integrated circuits. Their structure consists of many individual, similar, small-field electron emitters, usually organized in a regular two-dimensional pattern. FEAs need to be […]

Joan Elisabeth Adler (born 13 June 1950, in Sydney, Australia) is a computational physicist at the Technion - Israel Institute of Technology. Her research involves percolation theory, lattice models, and neural networks. Adler graduated with a B.Sc. in mathematics and physics from the University of Sydney in 1974. She completed her doctorate in physics in […]

Electrodynamic tethers (EDTs) are long conducting wires, such as one deployed from a tether satellite, which can operate on electromagnetic principles as generators, by converting their kinetic energy to electrical energy, or as motors, converting electrical energy to kinetic energy. Electric potential is generated across a conductive tether by its motion through a planet's magnetic […]

Alloantigen recognition refers to immune system recognition of genetically encoded polymorphisms among the genetically distinguishable members of same species (self-non-self discrimination). Post-transplant recognition of alloantigens occurs in secondary lymphoid organs. Donor specific antigens are recognized by recipient's T lymphocytes and triggers adaptive pro-inflammatory response which consequently leads to rejection of allogenic transplants. Allospecific T lymphocytes […]

A skyhook is a proposed momentum exchange tether that aims to reduce the cost of placing payloads into low Earth orbit. A heavy orbiting station is connected to a cable which extends down towards the upper atmosphere. Payloads, which are much lighter than the station, are hooked to the end of the cable as it […]

Super black is a surface treatment developed at the National Physical Laboratory (NPL) in the United Kingdom. It absorbs approximately 99.6% of visible light at normal incidence, while conventional black paint absorbs about 97.5%. At other angles of incidence, super black is even more effective: at an angle of 45°, it absorbs 99.9% of light. […]
