ZnO have nano sized structures and the arc discharge current has an effect on the structure size. TiO 2 nanostructures synthesized at 74 A arc current show diffuse reflectance from 49 % to 45 % in the NIR range (700 – 2500 nm). ZnO nanostructures show diffuse reflectance from 57 % to 14 % in the NIR range (700 – 2500 nm). KEYWORDS

What is Thru-Feed Grinding Thru-Feed Grinding is a production flat machining process that does almost everything a conventional double disc or vertical spindle grinder can do. Thru-feed grinding is the most efficient method known for high production surface grinding of small to mid size parts because it practically eliminates non-productive time.

A facile one-pot approach was developed for the synthesis of ZnO nanorods (NRs)/nanoparticles (NPs) architectures with controllable morphologies. The concrete state of existence of NPs and NRs could rationally be controlled through reaction temperature manipulation, i.e., reactions occured at 120, 140, 160, and 180 °C without stirring resulted in orderly aligned NRs, …

Total transmittance (T) and reflectance (R) spectra of sample Z along with their diffuse components (T D and R D) appear in Figure 2. From this figure, it is noticeable that the main sample-light interactions are diffuse in both cases, associated with the roughness of the surface. Measured T and R were the properties of the stack BGS - TiO 2-ZnO

The average grain size of the ZnO nanoparticles is in the range of 24-40 nm, depending on the mechanical grinding time. The UV-vis diffuse reflectance spectrum of the ZnO nanoparticles indicates a band gap of about 3.3 eV with an onset of absorption at about 3.1 eV, showing a weak red shift compared to 3.37 eV for the bulk ZnO.
