Electromagnetic spectrum

Silver nanoparticles (Ag NPs) were synthesized and characterized by transmission electron microscopy (TEM), X-ray powder diffraction (XRD), and absorption spectroscopy. Using Debye-Scherrer’s formula and the result of the XRD spectrum, the size of the Ag NPs was estimated at approximately 8 nm.

Before we can talk about solar power, we need to talk about the sun • Need to know how much sunlight is available • Can predict where the sun is at any time • Insolation : incident solar radiation • Want to determine the average daily insolation at a site • Want to be able to chose effective locations and panel tilts of solar panels

A photopolymer is a polymer that changes its properties when exposed to light, often in the ultraviolet frequency of the electromagnetic spectrum.Be bonds that link one polymer chain to another. Can be formed by chemical reactions that are initiated by radiation. Change physical properties of photopolymers.

Mass Spectrometry (a.k.a. MS or mass spec) – a method of separating and analyzing ions by their mass-to-charge ratio MS does not involve a specific region of the electromagnetic spectrum (because it is not directly interested in the energies of emitted photons, electronic or vibrational transitions, nuclear spin transitions, etc…)

Channel Assignment Problems (CAPs) occur in the design of cellular mobile telecommunication systems (Jordan, 1996; Katzela and Naghshineh, 1996; MacDonald, 1979); such systems typically divide the geographical region to be serviced into a set of cells, each containing a base station. The available radio frequency spectrum is divided into a set of disjoint channels; these must be assigned to the base stations to meet the expected demand of each cell and to avoid electromagnetic interference during calls....
