Influence of mode coupling on three, four and five spatially multiplexed channels in multimode step-index plastic optical fibers
(Elsevier, 2018-04-04)
We investigate the influence of mode coupling on space division multiplexing capability of three multimode step-index plastic optical fibers with different strengths of mode coupling. Results show that mode
coupling ...
Enhanced bandwidth of W type plastic optical fibers designed from singly clad step index plastic optical fibers
(Elsevier, 2018-11-02)
We propose a multimode W type (doubly clad) plastic optical fiber which takes the characteristic W-shaped index profile designed from a multimode singly clad step index plastic optical fiber upon modification of the cladding ...
Power Flow in Graded-Index Plastic Optical Fibers
(IEEE, 2019-07-03)
A method is proposed for predicting the evolution of the power distribution along graded-index plastic optical fibers. This method is verified against our recently reported measurements. The strong influence of mode coupling ...
Einstein type curvature tensors and Einstein type tensors of generalized Riemannian space in the Eisenhart sense
By using decomposition of curvature tensors of generalized Riemannian space in the Eisenhart sense, the Einstein type curvature tensors and Einstein type tensors of that space are determined and defined. All these tensors ...
Green synthesis and characterization of nontoxic L-methionine capped silver and gold nanoparticles
(Elsevier, 2019-12-11)
The simple green method for synthesis of stable L-Methionine (L-Met) capped silver (Ag@LM NPs) and gold (Au@LM NPs) nanoparticles (NPs) without adding any additional reduction agent or stabilizer was developed. Colloidal ...
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 ...
Tourism and sustainable development of rural settlements in protected areas - Example NP Кopaonik (Serbia)
(Elsevier Ltd., 2019-09-21)
With the formulation of tourism development strategies for the social and economic development of an area, rural tourism moved to a more complex phase of development. Numerous empirical studies have shown that different ...
Power flow in multimode W-type plastic optical fibers with graded index core distribution
(Elsevier, 2021-06-11)
A method is proposed for investigation of transmission along a multimode W-type (doubly clad) plastic optical fiber (POF) with graded index (GI) distribution of the core. The multimode W-type GI POF is designed from a ...
Synthesis, characterization, hydrolytic, and thermal stability of urea–formaldehyde composites based on modified montmorillonite K10
(Springer, 2022-02-11)
In this study, the thermal and hydrolytic properties of composite systems based on the urea–formaldehyde resin (UF) and eco-friendly montmorillonite (K10) as formaldehyde (FA) scavenger were examined. UF resin with molar ...
Thermal behavior of gamma-irradiated urea-formaldehyde composites based on the differently activated montmorillonite K10
(Springer, 2022-07-09)
This work investigated the thermal characteristics of irradiated composite materials formulated on the urea–formaldehyde resin (UF) and differently activated montmorillonite (K10). UF resin with molar ratio F:U = 0.8 was ...
