The 375 nm wavelength of UV-A is available as a substitute for X-rays in the double exposure technique. Research supported byJSPS KAKENHIGrant Number26460740.doi:10.1016/j.ejmp.2016.07.102Katsuda, T.Gotanda, R.Gotanda, T.Akagawa, T.
To explore the interaction of UV rays with two omicron variants of coronavirus, the team conducted a series of experiments. First, they isolated omicron BA.2 and BA.5 variants of SARS-CoV-2 from the infected cells (VeroE6/TMPRSS2). Next, they subjected the isolated omicron BA.2 and BA....
可添加单波长或多波长UV检测器,为共聚物分析或峰值鉴定提供成分分析。 malvern.com.cn malvern.com.cn There are five basic types of fluorochromes: small dyes (e.g. Fluoroscein isothiocyanate /FITC and Alexa dyes) protein dyes (PhycoerythrinAllophycocyaninGFP) Tandem dyes, where a protein dye collects...
X-rays are electromagnetic waves with very short wavelengths. Suppose an X-ray has a wavelength of 2.51 nm. What is its frequency? What is the frequency of blue light that has a wavelength of 448 nm? Answer in Hz. What are the frequency (in Hz) ...
Wavelengths are typically measured in the following units: Kilometers (km). Meters. Millimeters. Micrometers (μm). Nanometers. Picometers (pm). Femtometers (fm). The latter unit is used to measure shorter wavelengths on the electromagnetic spectrum, such as UV radiation, X-rays and gamma ...

source, the use of reflectors or optics to concentrate or contain the rays in a tighter surface impact area, and the distance of the source from the cure surface. The irradiance for UV LEDs at the cure surface decreases quickly as the distance between the source and the cure surface ...
A new technique of X-ray fluorescence analysis using ultrashort-wavelength X-rays was tested to obtain the K-series of spectra for rare-earth elements in t... TAKAHASHI,Yasuhiko,YAMAMOTO,... - 《Japanese Journal of Applied Physics Pt Letters》 被引量: 8发表: 1998年 X-ray and UV emission...
PP films were irradiated with 60Co γ-rays in vacuum or in air and stored in air. To clarify the difference of mechanical properties between the samples irradiated in vacuum and in air, the effect of cross-link was considered, together with the oxidation. The test presented that (among ...
The penetration depth of x-rays depends on their wave length. It is defined as the value where the primary intensity is reduced to l/e, or 37 percent of the initial value. In ceramics, the layer of residual stresses extend well below the surface, and there are high stress gradients withi...
