Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as grouping and read-across, emphasizing the need for...
Specular Reflectance –Specular reflectance, or SR, spectroscopy involves reflecting an IR beam directly off of the sample surface at such an angle that specular, or singular and direct, reflection occurs (as opposed to diffused reflection). SR typically occurs when testing glossy, flat, and reflec...
Using X-ray photoelectron spectroscopy (XPS), we observed no significant traces of oxygen (O 1s) on the surface of PTEAI-capped film, even after 640 min of accelerated aging tests (Fig. 5e), revealing that the PTEAI-capped MAPbI3 inhibits the formation of an oxygen-containing compounds...

Exitonic behaviour can be examined using various spectroscopy techniques, including an optical spectrometer. Excitonic properties will often determine the potential application of a material in ...
How could IR spectroscopy be used to distinguish between (CH3)3N and CH3NHCH2CH3? Define the following terms: a. Serial Dilution b. UV-Vis Spectroscopy c. Beer's Law. In organic chemistry, what is meant by titration? Describe the basic operating principle of a photodiode transducer. ...
An AIVC should be queryable with computational twins of today’s laboratory experiments, here called virtual instruments (VIs). Virtual experiments could, for example, simulate experiments in a cell type that is challenging to cultivate in vitro or simulate expensive readouts from low-cost ...
