Green photosynthetic bacteria harvest light and perform photosynthesis in low-light environments, and contain specialized antenna complexes to adapt to this condition. We performed small-angle neutron scattering (SANS) studies to obtain structural information about the photosynthetic apparatus, including the peripheral light-harvesting chlorosome complex, the integral membrane light-harvesting ...

To gain insight into surface processes in plasma processing, basic ion beam experiments are performed on two representative polyatomic-ion species: hydrocarbon ions CHx 1 for deposition processes and fluorocarbon ions CFx 1 for etching processes (x51,2, . . . ). A single ion species is extracted from an inductive plasma via a mass filter and directed onto aluminum surfaces at energies ,150 eV. ...

The goal of this article is to contribute to a more precise discussion of the question whether Lattice-Boltzmann (LB) methods can be regarded as efficient CFD solvers. After a short review of the basic model and recommendable extensions, we compare the accuracy and computational efficiency of two research simulation codes based on the LB and the Finite-Element method (FEM) for incompressible la...

Fluorinated carbon-based thin films offer a wide range of properties for many technological applications that depend on the microstructure of the films. To gain a better understanding on the role of fluorine in the structural formation of these films, CFx systems based on graphenelike fragments were studied by first principles calculations. Generally, the F concentration determines the type of ...

This work encompasses together a number of diverse disciplines (physiology, biomechanics, fluid mechanics and simulation) in order to develop a predictive model of the behaviour of a prosthetic heart valve in vivo. The application of simulation, for the study of other cardiovascular problems, such as blood clotting is also discussed. A commercial, finite volume, computational fluid dynamics (CF...

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...

OBJECTIVE This study aimed to assess the incidence of coronary anomalies using 64-multi-slice coronary computed tomography (MSCT). METHODS The diagnostic MSCT scans of 745 consecutive patients were reviewed. RESULTS The incidence of coronary anomalies was 4.96%. The detected coronary anomalies included the conus artery originating separately from the right coronary sinus (RCS) (n = 8, 1.07%...

The enhancement of the fluorination degree carbon fluorides (CFx) compounds is most effective method to improve energy densities Li/CFx batteries because specific capacity CFx proportional molar ratio F C atoms (F/C). In this study, B-doped graphene (BG) prepared by using boric acid as doping source and then BG utilized starting material for preparation CFx. B-doping enhances F/C without hinder...

The large-scale, multi-compartment PANDA facility (located at PSI in Switzerland) is one of the stateof-the-art facilities which is continuously upgraded to progressively match the requirements of CFD-grade experiments. Within the OECD/SETH projects, the PANDA facility has been used for the creation of an experimental database on basic containment phenomena e.g. gas mixing, transport, stratific...
