Nanospectroscopy of thiacyanine dye molecules adsorbed on silvernanoparticle clusters
(Elsevier, 2017-10-25)
The adsorption of thiacyanine dye molecules on citrate-stabilized silver nanoparticle clusters drop-cast onto freshly cleaved mica or highly oriented pyrolytic graphite surfaces is examined using colocalized surface-enhanced ...
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH GmbH, 2020-09-08)
The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ...
Figurative numbers contribution in perceiving the legality in numerous strings tasks and log-term memory of numerous data
(Modestum, 2019-01-27)
Contemporary mathematics teaching is mostly reduced to the application of algebraic
formulas and algebraic procedures. The visual-logical approach in solving
mathematical tasks is very little represented in teaching ...
Security and Standardization at E-learning platforms
(2021-07-01)
The process of developing e-learning is based on standards in the field of information security (ISO) and learning technologies (IEEE, IMS), and criteria for quality assurance have been taken as input parameters. The overall ...
Flexibility of curves on a single-sheet hyperboloid
Hyperbolic towers are towers in the shape of a single-sheet hyperboloid, and they are interesting in architecture. In this paper, we deal with the infinitesimal bending of a curve on a hyperboloid of one sheet; that is, we ...
Generating function for the figurative numbers of regular polyhedron
(Hindawi, 2020-04-14)
In this paper, we are going to demonstrate a method for determining the generating functions of tetrahedral, hexahedral, octahedral, dodecahedral, and icosahedral figurative numbers. The method is based on the differences ...
Edukacija u korak sa savremenim istraživanjima radona
(Društvo fizičara Srbije, Beograd, 2018-10-07)
Sistematska merenja koncentracije radona se najčešće izvode na slučajnim uzorcima stambenih objekata. Međutim, škole se mogu pokazati kao pogodniji izbor, jer su uniformno raspoređene po celoj teritoriji područja ili ...
Initial improvement of the hybrid accelerated gradient descent process
(Cambridge University Press, 2018-08-01)
We improve the convergence properties of the iterative scheme for solving unconstrained optimisation problems introduced in Petrovic et al. [‘Hybridization of accelerated gradient descent method’, Numer. Algorithms (2017), ...
Hybrid modification of accelerated double direction method
(Hindawi, 2018-11-06)
We present a hybridization of the accelerated gradient method with two vector directions. This hybridization is based on the usage of a chosen three-term hybrid model. Derived hybrid accelerated double direction model keeps ...
Hybridization Rule Applied on Accelerated Double Step Size Optimization Scheme
A hybrid accelerated model with two step length parameters for solving unconstrained optimization problems is presented. Applied hybridization process involves an efficient three term hybrid method. The accelerated double ...
