Fluorescence quenching properties of copper(II) ions have been used for designing Cu(II) sensitive fluorescent molecular probes. In this paper, we demonstrate that static quenching plays a key role in free Cu(II)-mediated fluorescence quenching of a near infrared (NIR) fluorescent dye cypate. The Stern-Volmer quenching constant was calculated to be KSV = 970,000 M in 25 mM MES buffer, pH 6.5 at...

In this paper, we study the quenching behavior of solution of a nonlinear parabolic equation with a singular boundary condition. We prove finite-time quenching for the solution. Further, we show that quenching occurs on the boundary under certain conditions. Furthermore, we show that the time derivative blows up at quenching point. Also, we get a lower solution and an upper bound for quenching ...

Cerenkov counting is a convenient and effective method of high-energy beta radiation, which has long been used to measure number radionuclides, such as, in particular, 90Sr+90Y, environmental objects. The traditional requires the use radiochemical sample preparation procedures, but these procedures may be simpler than those used, for example, liquid scintillation (LSC) method. We proposed Ceren...

Within the framework of time-dependent Ginzburg-Landau theory we show that circularly polarized terahertz or far-infrared radiation induces a dc supercurrent influences dynamics vortex-antivortex pair formation in mesoscopic superconductor undergoing rapid thermal quenching. The Lorentz force arising from supercurrents promotes separation and allows survival vortex polarity defined by helicity ...

Jet quenching in heavy ion collisions and particular the sub-structure of quenched jets are promising tools for investigating microscopic processes underlying jet background medium's response to energy momentum depositions. A quantitative understanding data can, however, be complicated by presence initial state radiation reconstructed jets. Using an extended version Jewel effect on different ob...

Subcritical austenite reverse transformation quenching was used to improve the mechanical properties of 30CrMnSi steel, and the microstructure and mechanical properties of the samples were analyzed by subcritical austenite reverse transformation quenching. Experimental results show that subcritica...

Performance, safety and environmental considerations can make gas quenching an attractive alternative to conventional oil, polymer and water quenching. But up to now, it has not experienced wide spread implementation due to some issues restricting introduction of this technology. Compared with liquid quenching, the specific advantages of gas quenching include cleaner product surfaces, avoidance...

We investigate the timescale with which IR luminosity decreases after a complete and rapid quenching of star formation using observations local high-redshift galaxies. From SED modelling, we derive time since subsample 14 galaxies from Herschel Reference Survey suffering ram-pressure stripping due to environment Virgo cluster 7 rapidly quenched COSMOS selected through state-of-the-art statistic...
