Silica-silicon composites for near-infrared reflection: A comprehensive computational and experimental study

Progress in Silica Chemistry – Determination of Physico-Chemical Parameters via Near-Infrared Diffuse Reflection Spectroscopy

In analytical chemistry, silica gel plays a pre-dominant role in separation science. It is the most important stationary phase in chromatography and electrophoresis. Separation efficiency is directly dependent on the quality and physical properties of the chromatographic bed. Therefore, methods for the physicochemical characterisation of silica stationary phases have been developed over the pas...

Integrating Spheres for Mid- and Near-infrared Reflection Spectroscopy

Experimental study of fracture mechanics in the aluminum matrix composites containing Fifteen percent silicon carbide particles

In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...

A Survey of Near Infrared Emission in Visual Reflection Nebulae

We present a survey for extended 2.2 μm emission in 20 new visual reflection nebulae, illuminated by stars with temperatures of 3,600 — 33,000 K. We detect extended 2.2 μm emission in 13 new nebulae, illuminated by stars with temperatures of 6,800 – 33,000 K. For most of these 13 nebulae we have measured J −K, H −K, and K −L, as well as obtaining surface brightness measurements at the wavelengt...
