Transformer insulating oil nanofluid is made to improve dielectric and thermal properties of the oil by employing nanoparticles with proper properties. In the current work, nanofluids based on transformer mineral oil were prepared by three procedures using diamond nanoparticles with high thermal conductivity, as well as high dielectric properties. It was tried to consider the impacts of surfact...

Diamond, which has excellent physical properties, is attractive for use in industrial applications. Because diamond is rated the highest for hardness and heat conductivity among all known materials, it is widely used for products such as abrasive grains, cutting tools, and heatsinks. Diamond also exhibits excellent transparency even in the ultraviolet range and can be applied to optical tools. ...

This report describes the results of a number of different, but related, laser Raman studies on various CVD diamond samples. It attcmpts to show the versatility of Raman spectroscopy as a diagnostic tool for the quality of diamond films, by demonstrating its use in a few novel applications. The studies of the laser Raman spectra of amorphic diamond and CVD diamond films are performed using lase...

Characterization of Cu/diamond interface thermal conductance (hc) and an improved understanding of factors affecting it are important, as Cu-diamond composites are increasingly being considered for electronic packaging applications. In this study, ~90 nm thick Cu layer was deposited on synthetic as well as natural diamond substrates. In several specimens, a Ti-interface layer of thickness ≤ 3.5...

BACKGROUND Granulocyte colony-stimulating factor has had a major impact on the management of severe chronic neutropenia--a collective term referring to congenital, idiopathic, or cyclic neutropenia. Almost all patients respond to G-CSF with increased neutrophils, reduced infections, and improved survival. Some responders with congenital neutropenia (termed Kostmann's syndrome herein) and Shwach...

statement of problem: in some clinical situations, repair of composite restorations is treatment of choice. improving the bond strength between one new and old composite usually requires increased surface roughness to promote mechanical interlocking since chemical bonding might not be adequate. similarly, the treatment of a laboratory fabricated resin composite restoration involves the same pro...

Lanthanides are vital components in lighting, imaging technologies and future quantum memory applications owing to their narrow optical transitions and long spin coherence times. Recently, diamond has become a pre-eminent platform for the realisation of many experiments in quantum information science. Here we demonstrate a promising approach to incorporate Eu ions into diamond, providing a mean...
