—Such an analysis is especially important because, although the phenomenon of progressive collapse have not a common occurrence, its effects can be catastrophes when the design methods are not sufficiently suited to slow down or stop the spread of damage throughout the structure. In addition to prevent the damages, th…

Tato diplomová práce se zabývá tvorbou polyelektrolytových komplexů chitosan-lignohumát, chitosan-polystyrensulfonát, chitosan-alginát a chitosan-karagenan. Práce je motivována hledáním vhodné alternativní látky za lignohumát. Metodou SEC-MALLS byly zjištěny molekulové hmotnosti použitých polymerů. Metodami izotermick…
Au nanoparticles (AuNPs) and superparamagnetic iron oxide nanoparticles (SPIONs), in various forms, are considered as biocompatible and are of great interest for diagnostic imaging and therapeutic applications. Biomedical applications of AuNPs originate from the surface plasmon resonance (SPR) effect. In order to tune…

Abstract : This project aims to (i) control graphene electronic structure by perturbing it using nanoparticles; (ii) fabricate graphene field-effect transistors and demonstrate their superior performances; (iii) investigate the THz and sub-THz characteristics of graphene layers. We have demonstrated engineering the ba…
This thesis deals with the influence of crystal defects of gold nanocrystals, especially on the synthesis and self-assembly of gold nanocrystals whose crystal defects and size are controlled. During this work, a method have been developed to separate single and polycrystals with similar size using crystalline segregat…
The paper proposes a new mathematical model for researching strength of structures of inhomogeneous medium. The method of finite elements is used. Numerical procedures for the implementation of the mathematical model are designed. A new stiffness matrix composite finite element is developed. The stiffness matrix is no…
Diplomová práce se zabývá problematikou přímé syntézy polymerů kyseliny mléčné. Teoretická část je zaměřena na výrobu kyseliny mléčné jako monomeru, a to jak přírodní, tak i syntetickou cestou, jejich výhodami a vlastnostmi. Dále se teoretická část zaměřuje na syntézy poly(mléčné kyseliny) (PLA) z laktidu a přímou pol…
This paper presents the characteristics of sensing DC corona discharges that produced at a needle-shaped electrode placed in the homogeneous electric field which simulates the atmospheric electric field under thundercloud. The major points of interest for this purpose are the detection sensitivity and polarity effect…
Diese Arbeit untersucht die Optimierungsmöglichkeiten eines Iridium-Katalysators für die Sauerstoffentwicklung bei der Elektrolyse mittels Protonen-Austausch-Membran. Aufgrund der hohen Kosten für die Synthese werden zwei Ansätze verfolgt, die Kosten ohne gravierende Effizienzverluste zu reduzieren. Zuerst wird die ko…
The evolution of the plastic strain localization field of ductile metals was followed by electronic speckle pattern interferometry (ESPI) during a uniaxial tensile test. It was shown that the mathematical model, a system of two crossing straight bands, describes accurately the evolution of the strain rate field from d…
Alumunium Matrix Composite (AMC) yang diperkuat partikel SiC merupakan material alternative untuk menggantikan besi cor sebagai bahan Cylinder Liner. Penggunaan AMC tersebut beralasan karena memiliki kekuatan spesifik dan kekakuan yang tinggi selain itu modulus elastisitas dan ketahanan aus nya pun tinggi. Salah satu…
The focus of this research is to investigate the potential of cellulose nanocrystals (CNC) as reinforcement in typical glass fiber/epoxy sheet molding compounds (SMC). The hypothesis is that addition of CNC can improve the properties of the SMC composites, allowing glass fibers to be removed thus reducing the density/…
We report, as an example, a complete analysis of nuclear spin-lattice relaxation time $({T}_{1})$ data for the strongly correlated antiferromagnet ${\mathrm{UPtGa}}_{5}$, which has a typical ${\mathrm{HoCoGa}}_{5}$ (115) structure. Using a high-quality single-crystal sample, the $T$ dependence of ${T}_{1}$ at $^{195}\…
Influencia del espesor del recubrimiento de elementos de hormigón armado expuestos a procesos de corrosión y sometidos a cargas externasRESUMENAl realizar estudios sobre corrosión en hormigón armado, es importante considerar en los ensayos, la acción de cargas externas, pues esta situación es la más frecuente en las e…
Controlled syntheses in nanoscale structures is expected and phosphorous nanotubes with predefined chiralities are important in electronic devices with tunable bandgap. Herein, by incorporating molecular dynamics simulations and theoretical analyses, we predict that a zigzag phosphorene nanoribbon can self-assemble an…
Resistencia al fuego de perfiles pultruídos de polímero reforzado con fibras de vidrio (GFRP) para aplicaciones en rehabilitación: Estudio experimental, numérico y analíticoRESUMENEl presente artículo presenta un estudio sobre la resistencia al fuego de vigas fabricadas con perfiles pultrusionados de polímero reforzad…
Abstract We report room-temperature ferromagnetism in ∼104–133 nm nanofibers of La0.5Sr0.5Ti1− x Ni x O3 (0.02 ≤ x ≤ 0.05). As-spun nanofibers of La0.5Sr0.5Ti1− x Ni x O3 are fabricated by an electrospinning technique. Nanofibers of the as spun and calcined La0.5Sr0.5Ti1− x Ni x O3 samples are characterized using X-ra…
Structural characterization of proteins is essential for understanding life processes at the molecular level. However, only a fraction of known proteins have experimentally determined structures. That fraction is even smaller for protein-protein complexes. Thus, structural modeling of protein-protein interactions (doc…
