Calculate the wavelength of light in vacuum that has a frequency of 4.2 *10^5 Hz. Calculate the wavelength of 91.5 MHz and the wavelength of an X-ray at 30 x 1015 Hz. Calculate the wavelength of light in vacuum that has a frequency of 5.26 \times 10^{16} Hz. How...
The functional groups of the prepared AC are identified using Fourier transform infrared (FTIR) spectrometer with a wavelength range of 400–4000/cm (Bruker Vertex 70, Bruker Company, Billerica, MA, USA). Preparation of jojoba grease Jojoba crops are favorably planted and cultivated in dry and ...
Convert a wavelength of 218 Angstroms tocm−1. Angstrom: The angstromÅ(Å)is a length measurement that is equal to1×10−10mor0.1of a nanometer. While this angstrom unit is not really following metric prefix convention, it is still considered as a metric unit. The distances between ...
Cu Kα X-ray source (GeniX3D Cu ULD), generated at 50 kV and 0.6 mA, was utilized to produce X-ray radiation with a wavelength of 1.5418 Å. A semiconductor detector (Pilatus 300 K, DECTRIS, Swiss) with a resolution of 487 × 619 pixels (pixel size = 172...

Photosystem II (PSII) catalyzes light-induced water splitting, leading to the evolution of molecular oxygen indispensible for life on the earth. The crystal structure of PSII from cyanobacteria has been solved at an atomic level, but the structure of eukaryotic PSII has not been analyzed. Because...
A low-index coating can also be used in applications where a high numerical aperture (which is related to the ability of an optical fibre to collect light [33]) is required. It is also important that the protective coating is applied uniformly across the length of the fibre and is ...
especially for ENE direction. The temperature shift has little effect on variation of α and AOD. AOD increase with relative humidity when α is greater than 0.5though dust aerosols are hydrophobic in this study. Key words:Beijing;aerosol optical depth;Angström wavelength exponent;meteorological fac...
Modulation of protein function through allosteric regulation is central in biology, but biomacromolecular systems involving multiple subunits and ligands may exhibit complex regulatory mechanisms at different levels, which remain poorly understood. Here, we discover an aldo-keto reductase termed AKRtyl and ...
Compared with the RGSs, the EPIC instruments have a broader wavelength coverage of 1.2–60 Å, but their spectral resolution is much lower (E/DEE20–50)30,31. In addition to X-ray telescopes, XMM- Newton has also an optical monitor. However our target is too bright in visual light to...
