Organic thermoelectric devices (OTEDs) are recognized one of the next generation energy conversion platforms because of their huge potentials for securing electricity continuously from even tiny heat sources in our daily life. The advantage of OTEDs can be attributable to the design freedom in device shapes and the low-cost fabrication by employing solution coating processes at low temperatures...
nanofber mats of poly(ε-caprolactone)/nanoclay nanocomposites were fabricated by electrospinning. the effects of the solution concentration and the nanoclay content of nanocomposite materials on the fnal nanofber structure were investigated. morphology and diameter of the nanofbers were studied using optical and scanning electron microscope. it was observed that the poly(ε...
Head-mounted displays (HMDs) have the potential to overcome some of the technological limitations of currently existing automotive head-up displays (HUDs), such as the limited field of view and the restrictive boundaries of the windshield. However, in a formative study, we identified other, partially known problems with HMDs regarding content stability and occlusion. As a counter-measure we pro...
Laser microbeam microdissection and laser pressure catapulting offer the possibility of separating cell compartments, thus allowing for contamination-free analysis. Using these methods, we were able to select single chloroplasts of Nicotiana tabacum. Starting from homogenized leaf material, chloroplasts were purified by differential centrifugation and applied directly onto a poly-ethylene-napht...
We have focused a beam (BL3) of FLASH (Free-electron LASer in Hamburg: lambda = 13.5 nm, pulse length 15 fs, pulse energy 10-40 microJ, 5 Hz) using a fine polished off-axis parabola having a focal length of 270 mm and coated with a Mo/Si multilayer with an initial reflectivity of 67% at 13.5 nm. The OAP was mounted and aligned with a picomotor controlled six-axis gimbal. Beam imprints on poly(m...
In this paper, we propose and design a new Head Mounted Display (HMD) that provides a large field of view with a high resolution insert. Previously, this type of HMDs has been designed using mechanical or sequential scanning devices. Our HMD uses only electronic devices that can be easily integrated with the optical components. We describe the design principles and envisioned applications of ou...
