These examples are programmatically compiled from various online sources to illustrate current usage of the word 'diffraction grating.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Brittany Trang, Milwaukee Journal Sentinel, 15 June 2021 The colors are from the chocolate (not any ingredient or coating) diffracting light after being forcefully molded onto a diffraction grating in vacuum. 2021 The beam was split because of the glass slide, a diffraction grating with thousands of tiny slits etched into it. The definition of diffraction is the spreading of waves as they pass through or around an obstacle. 2021 The basic idea is to pass the light through a diffraction grating-a bunch of very tiny parallel slits. Elizabeth Gamillo, Smithsonian Magazine, 9 Dec. Diffraction is an optical effect which limits the total resolution of your photography no matter how many megapixels your camera may have. 2022 The arrangement splits and diffracts light into several beams in different directions in an optical concept known as diffraction grating. Tomas Weber, Smithsonian Magazine, 23 Dec. attenuators, filters, transducers and multiple state memory).Recent Examples on the Web Through an electron microscope, Parker saw that Wiwaxia had a diffraction grating on its body, meaning a nanostructure composed of a series of parallel grooves that split wavelengths of light into colored rays, like the bottom of a CD. The types of materials we investigate have potential applications in energy conversion, transparent conducting oxides, gas sensors, catalysts, low temperature co-fired ceramics, dielectric ceramics, solid oxide fuel cells, and electronics (e.g. There is a continual need for: 1) a better understanding of composition-structure-property relationships, 2) new compounds/materials with improved properties, and 3) more economical compounds/materials. The results of the research are presented at conferences and in publications. Group members learn about conducting literature searches and manuscript writing. Measurements of their chemical and properties are conducted using electrical and dielectric characterization as a function of temperature and atmosphere, magnetic measurements, and photocatalytic properties. Characterization of their resulting phase assemblages and crystal structures is conducted through the use of X-ray diffraction techniques and crystallography. Approaches for materials design and discovery include a target approach using structure prediction, a directed approach using chemical intuition and substitutions, and exploratory through phase diagram development. In our research laboratory we utilize various solid state synthesis methods including conventional high temperature (up to 1600 ℃), flux, solvothermal, sealed tube and gas flow reactions. My research group is interested in the synthesis and characterization of solid-state inorganic materials and in fundamental structure/property relationships of solid state oxides.
