  • excited state
  • If the relaxation process of an excited state is accompanied by any orientational change of the transition dipole moment, transient anisotropy spectroscopy provides information on the temporal evolution of the molecular orientation. (kit.edu)
  • treatment
  • In the present research, aimed at monitoring the photocatalytic treatment of olive oil mill wastewater in a batch photoreactor containing a catalytic (TiO 2 ) membrane, an investigation was made of the principal parameters affecting the water treatment process, such as the variation in concentration between the beginning and the end of the photocatalytic process of compounds selected as indicators, i.e., polyphenols, or COD variation.

  • Features
  • All features must be compensated for surface and lateral etching, which happen simultaneously during the etching process. (photofabrication.com)
  • However, Irving and Reid were unable to obtain any direct evidence that phenyl free radicals are produced by photodecomposition of diphenyliodonium iodide in chloroform solution with methylmethacrylate monomer, and stated that the increased formation of iodine and especially the formation of benzene are the most striking features which distinguish the photochemical decomposition of diphenyliodonium iodide in chloroform from its thermal decomposition.

  • materials
  • In this respect, investigation of photophysical and photochemical processes in soft gel materials has recently emerged as a new and promising research field oriented towards expanding their applications in important areas such as photovoltaics, photocatalysis and phototherapy. (rsc.org)
  • Both fluorescence and phosphorescence are examples of the general process of light emission by excited materials known as luminescence. (encyclopedia.com)
  • Photopolymers are very interesting as optically sensitive recording media due to the fact that they are inexpensive, self-processing materials with the ability to capture low-loss, high-fidelity volume recordings of 3D illuminating patterns. (hindawi.com)
  • Their versatility, ease of use, and self-processing ability give them many advantages over more traditional materials such as silver halide and DCG [ 10 , 11 ]. (hindawi.com)
  • type
  • Especially under hypoxia, Ru2 still retained an excellent PDT effect, which can be attributed to the direct charge transfer between the excited PS and an adjacent substrate through a type I photochemical process, forming highly-oxidative hydroxyl radicals to damage tumor cells. (rsc.org)
  • metals
  • While PEI typically coats both sides of a metal sheet previously cut to size, in some cases, metals in thinner gauges can bypass the prep process and the resist can be applied to the entire coil. (photofabrication.com)
