Nanofocus diamond X-ray windows: Thermal modeling of nano-sized heat source systems

Nano-crystalline Diamond Films for X-ray Lithography Mask

Myoanatomy of the velvet worm leg revealed by laboratory-based nanofocus X-ray source tomography.

X-ray computed tomography (CT) is a powerful noninvasive technique for investigating the inner structure of objects and organisms. However, the resolution of laboratory CT systems is typically limited to the micrometer range. In this paper, we present a table-top nanoCT system in conjunction with standard processing tools that is able to routinely reach resolutions down to 100 nm without using ...

Thermal Plasma Synthesis of Nano-sized Powders

Thermal plasmas, normally generated by DC (direct current) arc or inductively coupled RF (Radio Frequency) discharge, can be described as a high enthalpy flame with extremely high temperature fields (1,000~20,000 K) and a wide range of velocity fields from several m/s [1-5] to supersonic values [6-7]. Since the resultant huge enthalpy can be realized for various kinds of plasma forming gases an...

Diamond Monochromator for High Heat Flux Synchrotron X-ray Beams

2 Single crystal silicon has been the material of choice for x-ray monochromators for the past several decades. However, the need for suitable monochromators to handle the high heat load of the next generation synchrotron x-ray beams on the one hand and the rapid and on-going advances in synthetic diamond technology on the other make a compelling case for the consideration of a diamond monochro...

Thermal windows and heat exchange

Endothermic animals, such as birds and mammals, regulate their body temperature balancing the amount of heat metabolically produced and that exchanged with the environment. Thus, whenever ambient temperature rises and/or metabolic heat production increases (such as during exercise), adjustments to promote heat dissipation are activated to defend body temperature. One of such adjustments modulat...
