Zone plates are high quality optics that have the potential to provide diffraction-limited nano-focusing of hard X-ray free electron laser radiation. The present publication investigates theoretically the temperature behavior of metal zone plates on a diamond substrate irradiated by 0.1 nm X-rays from the European X-ray Free Electron Laser. The heat transfer in the optic is simulated by solving...

In order to study the influence of nano-clay on crack resistance cement-based materials, two kinds nano-metakaolin (NMK) and nano-attapulgite clay (NMA) were considered. The early cracking process mechanical properties cement mortar (NCM) was studied by using a plate knife-edge constraint test. Based fractal theory, distribution characteristics NCM surface cracks revealed, calculation method fo...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

We have demonstrated the first observable case of efficient energy transfer from poly-ligands to terbium ions through cross-linked siloxane in solution. The intensification of green luminescence was easily perceived by the naked eye under UV-254 nm illumination, where even the terbium dopants reached 0.1 μM. Moreover, the nano-scale fibrous structure (diameter 100-200 nm) aggregated to a micro-...

We developed two types of in-situ three-dimensional imaging systems on the basis of full-field transmission X-ray computed tomography (XCT) methods for polymer electrolyte fuel cells (PEFCs) under operating conditions at beamline BL36XU at SPring-8. One was for a wide field of view (more than 500 μm) to obtain the whole membrane electrode assembly (MEA) images, and the other was for nano spatia...

For increasing first law efficiency in terms of COP and Second law efficiency (Exergetic Efficiency) of VCR systems.the experiment is performed on VCR system to study the effect of silver oxide Nano particle(50nm) in base fluid of ethyl glycol (50:50 ratio with water) with concentration factor 0.02 to 0.06g by volume % on hot side of system (condenser side). For high efficiency out-put, the pla...

Deposition of colloidal- and nano-scale particles on surfaces is critical to numerous natural and engineered environmental, health, and industrial applications ranging from drinking water treatment to semi-conductor manufacturing. Nano-scale surface roughness-induced hydrodynamic impacts on particle deposition were evaluated in the absence of an energy barrier to deposition in a parallel plate ...
