Single-use aluminum foil-based laser desorption/ionization (LDI) target plates have been developed for mass spectrometry (MS) analysis and provide detection results comparable to those of commercial stainless steel plates while offering a convenient way to avoid the time-consuming surface cleaning process. Additionally, arrays of TiO(2) nanoparticle spots are coated on the foil either by screen...

The work describes a compliance control scheme for the caudal joint motion of a biomimetic autonomous underwater vehicle (BAUV). The purpose of the control method is to use the motor power more effectively for propulsion. A symmetric foil executing large-amplitude sway and yaw motions in a flow imitates a flapping tail fin which is used as the propulsive device of BAUV. Motions of the oscillati...

In this study, the flow characteristics of a flapping foil power generator with a passively flapping flat plate have been investigated using the lattice Boltzmann method (LBM) and immersed boundary method at Reynolds number of 1100 based on the chord length. The aim is to explore potential benefits of flow induced passive actuation of the flat plate tail to the power output and efficiency. The ...

cupper oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. the structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. sem images show gradual development of hierarchical structures of copper oxide with different morphology. in order to study the effect of reaction time and te...

The prospects for producing orientation of the 1s level in highly charged ions using tilted foils is discussed. We analyse the transfer of orientation from the initial orbital angular momentum of an ion emerging from a foil to the ground-state spin via a combination of the spin–orbit interaction and cascade decays. An enhancement of the orientation can be obtained using a multi-tilted-foil tech...

A lens system is proposed that not only provides spherical correction of the objective lens by charges that are induced on a thin foil, in the way proposed in a paper by Otto Scherzer [Optik 56(2), 133-147, 1980], but also provides Zernike phase contrast by means of an appropriate phase shift of the scattered electrons within the foil. This system has the potential to provide strong phase contr...

The plasma physics group at GSI investigates among other issues the energy loss of heavy ions in laser produced plasma [1]. The current experimental setup consists of an ion beam from the UNILAC accelerator that penetrates a thin carbon foil which is irradiated by an intense laser beam, e.g. the nhelix or PHELIX laser. The foil is turned into a hot plasma while the ions pass through it and the ...

Flow over a traveling wavy foil with a passively flapping flat plate has been investigated using a multiblock lattice Boltzmann equation and the immersed boundary method. The foil undergoes prescribed undulations in the lateral direction and the rigid flat plate has passive motion determined by the fluid structure interaction. This simplified model is used to study the effect of the fish caudal...

OBJECTIVE To treat binocular diplopia secondary to macular pathology. METHODS Seven patients underwent evaluation and treatment. All had constant vertical diplopia caused by various maculopathies, including subretinal neovascularization, epiretinal membrane, and central serous retinopathy. Visual acuity ranged from 20/20 to 20/30 in the affected eye. All except 1 patient had a small-angle, co...
