simple and economic coating monitoring technology. The light-emitting properties of the novel coating can serve as an indicator layer, which warns when the coating has worn off, replacing or recoating is necessary [7]. When we inspect on coating with a hand-held UV-lamp, the yellowgreen light of SrAl2O4:Eu, Dy3+ will disappear. It means that the functional coating is worn out and that recoating...

Understanding fluorescence quenching processes of organic dyes by biomolecular compounds is of fundamental importance for in-vitro and in-vivo fluorescence studies. It has been reported that the excited singlet state of some oxazine and rhodamine derivatives is efficiently and almost exclusively quenched by the amino acid tryptophan (Trp) and the DNA base guanine via photoinduced electron trans...

The development of activatable photodynamic therapy (PDT) has demonstrated a utility for effective photosensitizer quenchers. However, little is known quantitatively about Forster resonance energy transfer (FRET) quenching of photosensitizers, even though these quenchers are versatile and readily available. To characterize FRET deactivation of singlet oxygen generation, we attached various quen...

Artificially mediated linear (methylviologen) and cyclic (phenazine methosulfate) electron transport induced zeaxanthin-dependent and independent (constitutive) nonphotochemical quenching in osmotically shocked chloroplasts of pea (Pisum sativum L. cv Oregon). Nonphotochemical quenching was quantitated as Stern-Volmer quenching (SV(N)) calculated as (F(m)/F'(m))-1 where F(m) is the fluorescence...

We calculate the jet quenching parameter in medium with chemical potential from AdS/CFT correspondence. Our result is summarized in a plot. Moreover, we extract the explicit form of the jet quenching parameter of medium with small chemical potential for phases of dual SYM corresponding to large and small black holes. For the former phase, the jet quenching is increased as the charge density inc...

Abstract This paper is based on a keynote lecture presented by Prof. Fechte-Heinen during the 2 nd International Conference Quenching and Distortion Engineering in April 2021. Firstly, it presents short summary of basics distortion formation. The mechanisms potential for with its carriers are discussed more detail. Furthermore, method explained. Finally, selected examples that illustrate connec...
