Two d i f f e r e m kynthetic diamond-based Xray transmitting beam position monitor (XBPM) prototypes have been studied with an undulator white beam at the European Synchrotron Radiation Facility (ESRF) ID-6 beamline. Of particular interest was the possibility of designing an integral window and filtedphoton beam position monitor for the Advanced Photon Source (APS) high heat flux insertion dev...

A black layer coating for an aluminum-photoresist interface with a reflectance less than 0.1% for 413-nm, s-polarized light incident at 25 degrees is described. It is made of space-compatible materials, and its rms roughness is less than 15 A.

Enhancing water shedding behavior on aluminum surfaces is important in the design of energy-efficient heat exchangers. In this work, a method for fabricating oil-infused aluminum surfaces for HVAC&R systems is described for the purpose of exploiting the slippery nature of such surfaces, thereby improving the overall surface wettability. A microstructured, porous aluminum fin stocks with heterog...

We show that thin diamond coatings can dramatically enhance the performance of micrometer-scale cutting tools. We present a new approach for coating 300 μm diameter tungsten carbide (WC) micro endmills using a tailored seeding method and hot filament chemical vapor deposition (HFCVD) to obtain uniform, conformal, and continuous diamond coatings less than 2 μm in both thickness and grain size. T...

. Surface characterization techniques were used to evaluate adamantylethyltrichlorosilane (AdSi) as a potential coating to provide surface protection or as an initiator for diamond-like thin films. FT-IR and FT-Raman results indicate that, after formation and heating, the coating system has developed a cross-linked siloxane network. Quartz crystal microbalance and contact angle measurements wer...

In the present work, based on high frequency wavelet analysis of dynamic signals of mechanical systems, a multiple-resolution wavelet analysis is carried out, to the signal obtained from an accelerometer mounted on the structure of a hip prosthesis wearing test device. The prostheses employed had a femoral head made of aluminum oxide and the acetabular cup of ultra-high-molecular-weight polyeth...

High surface area alumina coatings were prepared on surface acoustic wave (SAW) mass balances. These coatings were fabricated by anodic etching of evaporated aluminum films. The coatings consisted of roughly collinear pores penetrating through the monolithic alumina film. The nanoporous (NP) coatings were characterized by scanning electron microscopy, and the pore number density and diameter we...

A method is presented to improve the tool life and cutting performance of 300mm diameter tungsten carbide (WC) micro end mills by applying thin (o300nm) fine-grained diamond (FGD) and nanocrystalline diamond (NCD) coatings using the hot-filament chemical vapor deposition (HF-CVD) process. The performance of the diamond-coated tools has been evaluated by comparing their performance in dry slot m...

ÐFerron reagent and FTIR spectroscopy were used for the identi®cation and characterization of the aluminum species formed during dephosphorization of simulated wastewater with and without organic matter. Evidence from FTIR spectroscopy showed the formation of aluminum hydroxyphosphate, hydroxy-Al±tannate and aluminum complexes containing both phosphorus and tannic acid. The surface reactivity o...

The advancement of far-ultraviolet (FUV) coatings is essential to meet the specified throughput requirements of the Large UV/Optical/IR (LUVOIR) Surveyor Observatory which will cover wavelengths down to the 100 nm range. The biggest constraint in the optical thin film coating design is attenuation in the Lyman-Alpha Ultraviolet range of 100-130 nm in which conventionally deposited thin film mat...
