The SLC46A3 gene, also known by its aliases solute carrier family 46 member 3 and FKSG16, is located at 13q12.3 on the reverse strand in humans. [5] The gene spans 18,950 bases from 28,700,064 to 28,719,013 (GRCh38/hg38), flanked by POMP upstream and CYP51A1P2 downstream.
Energy-filtered transmission electron microscopy (EFTEM) is a technique used in transmission electron microscopy, in which only electrons of particular kinetic energies are used to form the image or diffraction pattern. The technique can be used to aid chemical analysis of the sample in conjunction with complementary techniques such as electron ...
Dual-energy imaging, i.e. imaging at two energy levels, is a special case of spectral imaging and is still the most widely used terminology, but the terms "spectral imaging" and "spectral CT" have been coined to acknowledge the fact that photon-counting detectors have the potential for measurements at a larger number of energy levels. [2] [3]
CT absorptions bands are intense and often lie in the ultraviolet or visible portion of the spectrum. For coordination complexes, charge-transfer bands often exhibit molar absorptivities, ε, of about 50000 L mol −1 cm −1. By contrast ε values for d–d transitions are in the range of 20–200 L mol −1 cm −1.
Solar cells operate as quantum energy conversion devices, and are therefore subject to the thermodynamic efficiency limit. Photons with an energy below the band gap of the absorber material cannot generate an electron-hole pair, and so their energy is not converted to useful output and only generates heat if absorbed.
HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...

In March 2020, Thermo Fisher Scientific received emergency use authorization from the FDA for a test for SARS-CoV-2 to help mitigate the COVID-19 pandemic. [citation needed] Thermo Fisher also partnered with its biopharma customers, including Pfizer and Moderna, to support the development and production of new mRNA-based COVID-19 vaccines. [49 ...
