  • emission
  • If the emission polarizer is vertically polarized there will be an additional loss of fluorescence as Brownian motion results in dye molecules moving from an initial vertical polarized configuration to an unpolarized configuration. (wikipedia.org)
  • lifetime
  • After a short delay (the average represented as the fluorescence lifetime τ {\displaystyle \tau } ), it comes down to a lower state by losing some of the energy as heat and emitting the rest of the energy as another photon. (wikipedia.org)
  • researchers
  • These facts, and the composition of the dagger had long suggested a meteoritic origin, however, evidence for its meteoritic origin was not entirely conclusive until June 2016 when researchers using x-ray fluorescence spectrometry confirmed similar proportions of metals (Iron, 10% nickel, and 0.6% cobalt) in a meteorite discovered in the area, deposited by an ancient meteor shower.

  • Analysis
  • This book brings together the knowledge and expertise of internationally recognised scientists with practical experience of in situ analysis using portable X-ray fluorescence technology. (rsc.org)
  • Thus, once deployed for use in a facility, the fluorescence information can be fiberoptically transmitted to a remote location, where data processing and analysis can be performed. (wikipedia.org)
  • molecular
  • Bonding mechanism of human serum albumin(HSA) and dibutyltin(DBT) that is the degradation product of tributyltin(TBT)which is main component of antifouling paint of ships on molecular level was investigated by fluorescence spectrometry for finding out the way and degree of mutual combination. (cnki.com.cn)
  • Combined with genetics and molecular biology techniques fluorescence microscopy provides an efficient tool for observing molecular phenotypes useful for dissecting the pathways of cell cycle progression and cell response to internal and external signals ( 7 ). (mcponline.org)
  • elements
  • Nganvongpanit K, Buddhachat K, Piboon P, Klinhom S (2016) The distribution of elements in 48 canine compact bone types using handheld X-ray fluorescence. (springer.com)
  • techniques
  • One of the variants of TXRF, often referred as fluorescence-assisted X-ray standing wave (XSW) is a powerful and versatile tool to unfold depth-resolved physical and chemical properties of nanostructured materials, as it combines the features of both X-ray reflectivity (XRR) and XRF techniques.

  • energy
  • Rowe H, Hughes N, Robinson K (2012) The quantification and application of hand-held energy-dispersive X-ray fluorescence (ED-XRF) in mudrock chemostratigraphy and geochemistry. (springer.com)
  • As I y = I ⊥ {\displaystyle I_{y}=I_{\perp }} , and I z = I ∥ {\displaystyle I_{z}=I_{\parallel }} , we have r = I ∥ − I ⊥ I ∥ + 2 I ⊥ = I ∥ − I ⊥ I T {\displaystyle r={\frac {I_{\parallel }-I_{\perp }}{I_{\parallel }+2I_{\perp }}}={\frac {I_{\parallel }-I_{\perp }}{I_{T}}}} . In fluorescence, a molecule absorbs a photon and gets excited to a higher energy state. (wikipedia.org)
  • performance
  • In this case we can decouple requirements for both modules and optimize the performance of each one independently for fluorescence microscopy and affinity purification experiments. (mcponline.org)
  • light
  • even before the laser existed, when conventional light sources were used to excite the fluorescence. (wikipedia.org)
  • SOFIA solves the problem of low collection efficiency, as it collects nearly all of the fluorescent light produced from the sample being analyzed, increasing the amount of fluorescence signal by around a factor of 10 over conventional apparatus. (wikipedia.org)
  • cells
  • Time-lapse phase-contrast (left) and fluorescence (right) movies of human ES cells (H9) grown in Essential 8 medium on vitronectin and transfected with 1 µL Lipofectamine Stem reagent complexed with a GFP-expression construct (500 ng total plasmid DNA). (thermofisher.com)
