ZnO and ZnO:Mn nanocrystals synthesized via reverse micelle method. The size, band gap, Urbach energy, optical constants and penetration depth of nanocrystals were calculated by UV-vis spectroscopy data. The surface morphology was studied with the use of scanning electron microscope (SEM). Moreover the samples exposed to Gama ray source of 60Co and their thermoluminescence properties...

Source emissions with high covariance degrade the performance of multivariate models, and often highly-time resolved data is needed to accurately extract contribution different emissions. Here, we use highly time-resolved size segregated elemental composition apportion sources fraction PM in Zürich (May 2019–May 2020). For collection, have used an ambient metals monitor, Xact 625i, equipped a s...

In this scientific research ZnS nanoparticle was synthesized via precipitation method. Two samples were synthesized by this method. The nanoparticle was characterized by XRD techniques, and the size and kind of crystallinity were identified by X-ray diffraction pattern as well. The size measurement has been done by using scherrer's equation. The average sizes of nanoparticles in two sa...

− This paper describes the uncertainty estimation of the size-of-source effect (SSE) measurement for the standard radiation thermometers in the indirect method using an integrating sphere with a black spot as the source. We checked the agreement between two processes of changing the black spot size and changing the aperture size. The SSE contributions of each uncertainty factors were analyzed.

snn = 17GeV a sudden increase in the pion source volume is observed for central PbPb collisions. This seems to imply that the pion phase density has reached a limit. The source size of different particles decreases with mass when the transverse velocity is held constant but increases with mass when mT is held constant. The antiproton source radius is larger than the proton source radius. So far...

in this paper, a new circuit is proposed for step-up z-source inverter based on qzsi (quasi-z-source inverter). the proposed topology inherits all advantages of the conventional topology. the proposed topology in comparison with conventional topology reduces the st (shoot-through) duty cycle by over 25% at the same voltage boost factor. theoretical analysis of the proposed qzsi in the st and no...
