Nucleic acid concentration determination is a common application in the life science industry. UV Vis spectroscopy is a popular method of this due to the accuracy of results and simplicity of use. For more information on the experimental method, please download the application note below. ...
A temperature of 120°C coupled with a heating time of 30 minutes was rejected for thermal sterilisation because of the high amount of free radicals produced by the drug samples. 展开 关键词: Chloramphenicol thermal sterilization free radicals EPR spectroscopy EPR spectra ...
In this regard, a characterization using different analytical techniques such as time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy (XPS), 3D profilometry, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), atomic force microscopy (...

of perovskite's composition was performed using Energy dispersive spectroscopy (EDS). The BET surface area and the textural properties of the perovskite were determined by N2adsorption/desorption isotherms obtained using the TriStar II 3020 system. To characterize the functional groups of the surface, ...
BF2 (free) was prepared by dissolving 720 mg of EGTA (10 mM) and 2.38 g HEPES in DI water, then adjusting to pH= 7.4 using conc. NaOH solution, then diluting the solution to 200 mL with DI water. 2.3.1. Fluorescence and UV-Vis spectroscopy, quantum yield and molar abso...
(UV) illumination [59], exerting a fairly unfavorable effect on device stability. To tackle this dilemma, other metal oxides with low or non-photocatalytic activity, such as SnO2[60], ZnO [61] and Zn2SnO4[62] [63,64], have been assessed as ETLs of PSCs. Among them, SnO2exhibits ...
(SEC) using Superdex 200 prep grade in the aforementioned phosphate buffer. The concentration of the initial crystallin mixture is adjusted to 40 mg/ml determined from UV-absorption with an extinction coefficient of 1.65 ml/(mg cm) [23] at 280 nm. The fractions corresponding to the ...
The optical properties of the NS-CDs were then examined by UV–visible absorption spectroscopy and fluorescence spectrometry. Fig. 4(A) shows that absorption peaks were observed at 240 and 345 nm. The former corresponds to the characteristic peak of the fluorescent CDs, which is attributed to th...
