Purpose Preliminary nuclear analysis performed for the CTS system ScopeThe results obtained in this preliminary analysis will be used for design support and optimisation of the CTS system, contributing to the Loads Specification and serving as input to the thermal analysis of the CTS invessel components.The models dev…
Werkstoffe für höchste Einsatztemperaturen spielen als Materialien für Turbinenschaufeln in Gasturbinen eine herausragende Rolle. Gängige Eisen (Fe)- und Nickel (Ni)-basierte Hochtemperaturmaterialien haben jedoch deutliche Nachteile wie Phaseninstabilität und niedrige Schmelztemperaturen. Um steigenden Leistungsanfor…
Polymer-derived ceramics (PDCs) offer a variety of unique features that outperform classical powder-sintered ceramics and make PDCs valuable candidates for challenging applications such as implantable MEMS. The precise controllability of the precursors’ chemical composition allows the adjustment of the functional prop…
Anatase TiO2 has attracted a lot of attention due to its applications as a photocatalyst in water and air treatment technologies. However, its large band gap energy (⁓3.2 eV) limits its application only to UV light. Also, anatase TiO2 suffers from high electron/hole recombination, which diminishes its photocatalytic a…
Particulate emissions cause millions of premature deaths every year and emissions from road\ntransportation makes a significant contribution. The last years more stringent emissions\nregulations will enforce the implementation of particulate filters and much of the health issues\ncan be significantly reduced. Since th…
This contribution presents the numerical analysis of Hartree-Fock’s method of computing electron atomic statefunctions using Galerkin’s finite element method. The underlying theory and computational implementation are presented in some detail for the first time and highly accurate energies are presented for free neutr…
Este proyecto tiene como objetivo el diseno y la fabricacion de soportes tridimensionales cuya finalidad radica en el estudio de la migracion de celulas tumorales hacia tejido sano. La novedad se encuentra en que, a dia de hoy, practicamente todos los ensayos de este tipo se llevan a cabo en placas de Petri, las cuale…
The high velocity impact resistance of fibre metal laminates (FMLs) based on combinations of aluminium alloys (6161 and 7075 series) and a glass fibre reinforced epoxy resin have been investigated using Digital Image Correlation (DIC) method and Finite Element (FE) method. A full-field deformations and strain for FMLs…
In recent decades, novel porous materials of porous organic frameworks (POFs), have received attentions thanks to their outstanding properties such as excellent porosity and rich strategies for post-synthetic functionalization. Due to its rich chemical and optoelectronic properties, introducing carbazole as the functi…
OPERA-PU-TUD321b Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Neth- erlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After…
Due to the high molecular weights the analysis of polymers is difficult to carry out. Their dissolution is usually limited and the vapor pressure is very low. However, the degradation of a polymer leads usually to smaller compounds which then enable volatile analysis to aid in the characterization of the degradation o…
La ocurrencia de deslizamientos rapidos se ha ligado a la perdida de resistencia efectiva a lo largo de la superficie de rotura debido a excesos de presion de agua inducidos por el calor generado durante el propio movimiento. La simulacion numerica de estos procesos se ha enfocado resolviendo la ecuacion de la dinamic…
Peach is a perishable fruit with shelf life of few days at natural environment that can be extended for weeks under refrigerated conditions. The chemical preservation of peach pulp is the best method for extending its shelf life and retaining its quality. In this research work Peach pulp was stored at 40°C to check th…
The evolution of the microstructure of multiphase metal matrix composite AlSi12CuNiMg with 7% vol. Al2O3 + 15% vol. SiC (short fibers and whiskers, respectively) was studied by synchrotron computed tomography. It comprehended as cast and after heat treatment conditions, as well as damage evaluation after ex-situ compr…
Graphene, a two dimensional allotrope of carbon in a honeycomb lattice, has gathered wide attention due to its excellent electrical, thermal, optical and mechanical properties. It has extremely high electron/hole mobility, very high thermal conductivity and fascinating optical properties, and combined with its mechani…
The paper deals with synthesis and studies the materials with high ionic conductivity on the basis of which the various electrochemical devices are created: gas sensors, electrolyzers, devices for dosed supply of hydrogen and water vapor, etc. Interest in the study of the physicochemical properties of oxide proton con…
Epoxy resins are one of the first choices for structural adhesives and are widely used in combination with fibers as fiber reinforced plastics (FRP). The mechanical properties are the result of the complex chemical network structure that is generated by the thermally catalyzed cross linking reaction. Numerical simulat…
We measured the integrated Stokes parameters P1, P 2, and P3 of Zn (43PJ – 53S1) fluorescence resulting from transversely-spin-polarized electron impact excitation of the Zn (4s5s)5 3S1 state. This work was motivated by a similar study from several years ago by Pravica et al., in which they measured non-zero values of…
Corrosion on the car underbody can affect critical parts, which poses safety risks. The current corrosion protection methods such as wax, sealers and coatings are not effective enough and an advance form of corrosion protection is desired. Implementation of smart coatings might be an effective solution. These coatings…
Thermoelectric (TE) materials, capable of harvesting waste heat and converting this into electricity, have shown promise for use in power generation and refrigeration. The application of TE materials to energy hungry processes, such as the operation of combustion engines or industrial furnaces, provides an opportunity…
