(b) (below) Familiar regions of the E–M spectrum. Eye What is light DH Sliney 226 and the responsivity of the observer. The lower limit is generally taken between 360 and 400 nm and the upper limit between 760 and 830 nm'. The limits of visibility have long been a personal interest...
(MFW). Assisted by numerical calculations, we reveal that a ‘perfect polishing point’ exists, i.e., the optimal interaction time for LP at a specific laser power density, at which the surface roughness can be minimised without the formation of an MFW owing to the Marangoni effect and non...
The universe is filled with electromagnetic radiation, and visible light covers only a small section of its spectrum. The dominant sources of light are stars, with the energy originating from nuclear fusion processes in their interior. The question of energy generation in our sun and in other sta...
Light-emitting electronic devices are ubiquitous in key areas of current technology, such as data communications, solid-state lighting, displays, and optical interconnects. Controlling the spectrum of the emitted light electrically, by simply acting on the device bias conditions, is an important goal ...
If the controversial 17-keV neutrino exists, laboratory, astrophysical, and cosmological bounds, unless significantly weakened, require that (1) it be a Ma... DO Caldwell,P Langacker - 《Phys Rev D Part Fields》 被引量: 596发表: 1991年 Physics and astrophysics of neutrinos Today, intense int...
Figure 6. HPS reference spectrum at a resolution of 1 nm and spectra at the EnMAP resolution for different VIS/NIR shifts (a) and SWIR (b); the sum of the signals normalized to 1. To estimate the shift for an image spectrum, we normalize the sum of the signal of the bands in th...
Light emission properties of a fluorene cross-conjugated polymer (PF–1) based on the monomer 4,7-bis[2-(9,9-dimethyl)fluorenyl] benzo[1,2,5]thiadiazole are reported. This polymer exhibits solubility at high concentrations, good processability into thin solid films of good quality and a broa...
This one just requires a bit of rearranging to maximize any light you have. Ensuring that a window is the first thing the eye goes to when walking into the room will make it seem like there is more natural light than actually exists. Here, muralistChampagneadorns her living room’s major...
varies with wavelength. Blue light deviates more than red when it passes through glass. Newton’s famous experiment of creating a spectrum by a prism relies on the fact that the refractive indices of glass with respect to lights of different wavelengths are different. Consequently, they are defle...
Here, we focus solely on Ohmic spectra. Continuum models of the environment only capture the continuous part of the environmental spectrum. The embedding protein, even though large molecular complexes, are still finite with discrete vibrational spectra. At least at high frequencies, the spectra ...
