1. In Situ Raman Spectroscopic Measurements Of Metal Oxides Under High Temperature 6/18/2019

   Transition metal oxides are compounds composed of oxygen bound to transition metals used in various applications such as heterogeneous catalysts. To study the mechanism of the catalytic process as well as monitor and optimize the reaction conditions, multiple analytical methods such as XAS, NMR, and Raman spectroscopy have been investigated. Raman spectroscopy has been widely utilized in in-situ catalytic process monitoring with metal oxides, even achieved multi-technique characterization by combining with other instrumentations.

4. What Is An EMI Shielding Window? 10/17/2019

   An EMI shielding window is an optically transparent, electrically conductive barrier that significantly reduces the amount of electro-magnetic radiation that might pass through it. This article covers the different types and their uses and benefits.

5. What Is A Neutral Density Filter? 11/21/2019

   A neutral density, or ND, optical filter reduces or modifies the intensity of all wavelengths or colors of light equally, therefore providing for no changes in the hue of the color rendition. Neutral density filters can be colorless or clear, or they can be grey in tone.
