The reactor pressure vessel (RPV) water level is critical information for confirming the condition of core cooling in severe accident situations. However, the measured RPV water level signal cannot be trusted during severe accidents due to the unknown integrity of the sensor. In this study, the RPV water level was pre…
The poor water solubility tops the list of undesirable physicochemical properties in the drug discovery and Solid Dispersions (SDs) has been frequently used to enhance dissolution of such compounds. Although, some challenges limit the studies of SD commercial application. During recent years, the Quality by Design (Qb…
Pre-turbo aftertreatment systems benefit from an increase of the temperature across the monolith reducing the time up to DOC light-off and reaching better conditions for passive regeneration in the DPF. The engine performance is also improved by reducing the specific fuel consumption. The pumping work diminishes becau…
We present an atomistic study on the D irradiation on W–Be mixtures, including a comparison between molecular dynamics (MD) and binary collision approximation methods. We compared the D reflection and Be erosion yields after the non-cumulative D impacts, concluding that both methods agree qualitatively, but low-energy…
We present a systematic comparison of conventional small-angle X-ray scattering (SAXS) with the relatively new real-space technique, spin-echo small-angle neutron scattering (SESANS). We apply both techniques to colloidal suspensions where the particles interact as hard spheres, with electrostatic repulsions, or with…
The engine and its exhaust flow behaviors are investigated in a turbo-charged gasoline direct injection engine under simulated cold-fast-idle condition. The metrics of interest are the exhaust sensible and chemical enthalpy flows, and the exhaust temperature, all of which affect catalyst light off time. The exhaust se…
Abstract Polymers made of renewable resources increasingly replace conventional plastic materials made of petroleum. Socalled bioplastics can be found e. g. in food industry, for agricultural usage or in the medical field. The range of applications can be further expanded with specialized coating of their surface. Esp…
Continuum mechanics, just as the name implies, deals with the mechanics problems of all continua, whose physical (or mechanical) properties are assumed to vary continuously in the spaces they occupy. Continuum mechanics may be seen as the symbol of modern mechanics, which differs greatly from current physics, the two…
We investigate by first-principles simulations the resonant electron-transfer lifetime from the excited state of an organic adsorbate to a semiconductor surface, namely, isonicotinic acid on rutile TiO 2 (110). The molecule–substrate interaction is described using density functional theory, while the effect of a truly…
Smallest variations of the lattice parameter result in significant changes in material properties. Whereas in bulk, lattice parameters can only be changed by composition or temperature, coherent epitaxial growth of thin films on single crystals allows adjusting the lattice parameters independently. Up to now only disc…
A circular polarization selective structure (CPSS) reflects one handedness of circular polarization and transmits the other. We present a new multilayer structure with significantly improved bandwidth compared to classical solutions, which are typically based on resonant structures. The proposed structure consists of…
Paclitaxel is a common chemotherapeutic agent that is effective against various cancers. The poor aqueous solubility of paclitaxel necessitates a large percentage of Cremophor EL:ethanol (USP) in its commercial formulation which leads to hypersensitivity reactions in patients. We evaluate the use of a crystalline nano…
:Benthic diatoms are the most common epiphytes on the surfaces of marine organisms. Although some epiphytic diatoms cause multimillion-dollar economic losses in commercially cultivated red algal plantations every year, such as Pyropia (formerly Porphyra), little is known about endophytic or pathogenic diatoms. We foun…
Cell sheet engineering has enabled the production of confluent cell sheets stacked together for use as a cardiac patch to increase cell survival rate and engraftment after transplantation, thereby providing a promising strategy for high density stem cell delivery for cardiac repair. One key challenge in using cell she…
Fuel consumption and NOx emissions of gasoline engines at part load can be significantly reduced by Controlled Auto-Ignition combustion concepts. However, the range of Gasoline Controlled Auto-Ignition (GCAI) operation is still limited by lacking combustion stability at low load and by high pressure-rise rates toward…
An inductive dichroic surface is presented for use as a sub-reflector in a tri-band satellite communications antenna system. The surface is designed to be reflective in the frequency range 10.7-12.75 GHz, situated in the Ku band, and transmissive at the two Ka sub-bands 17.3-20.2 GHz and 28.295-30 GHz. The large bandw…
An inherently safe thorium-breeder pebble bed reactor has great potential to improve the safety and sustainability of nuclear energy. The aim of this work is to determine the conditions under which breeding is possible in a thorium-breeder pebble bed reactor (PBR) and to present possible core designs for such a reacto…
Indium tin oxide (ITO) was deposited by RF sputtering on n-GaAs nanowires grown by the Au-assisted vapor?liquid?solid process in a molecular beam epitaxy (MBE) system. The ITO formed an Ohmic contact with n-doped (n = 8???1018?cm?3) GaAs nanowires with a specific contact resistance of <1.41???cm2. Insertion of a 25?nm…
Phase-pure lithium orthosilicate (Li4SiO4) was prepared by a solution-combustion technique using rice husk ash as a silica source. We found that by controlling the citrate-to-metal (C/M) ratio of the solution and the calcination temperature of the as-burnt powder, phase purity can be achieved. The particle size of the…
Wafer-level hybrid bonding with Cu/SiO2is a very promising technique to fabricate three-dimensional integrated circuits, because it enables high performance operation with low power consumption as well as low 3D stacking costs. For a successful hybrid bonding process, the particular bonding properties of unstructured…
