Since the procedures adopted in all these studies varied greatly it is conceivable that the diversity and the inconsistency of the results were partly due to the lack of a standardized procedure. The ...

Tohoku University researchers have revealed more details about omnidirectional photoluminescence (ODPL) spectroscopy—a method for probing semiconducting crystals with light to detect defects and ...

Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

Since the phenomenon of two-photon absorption (TPA) was first experimentally observed in 1961 1, it has attracted much research interest because of its potential application in three-dimensional ...

$$I = I_{0} \exp \,( - A{\kern 1pt} {\kern 1pt} ) = I_{0} \exp \,( - \varepsilon {\kern 1pt} c{\kern 1pt} {\kern 1pt} l{\kern 1pt} {\kern 1pt} )\,,$$ Recently, Martin ...

Anton Paar has introduced the Brabender AbsorptoMeter, an automated system designed to measure liquid absorption  and oil ...

The d-xylose absorption test is useful in the diagnosis of tropical and idiopathic sprue, 1–4 but results are variable in other disorders and in elderly persons without intestinal disease. 5,6 ...

Quantification of nucleic acid concentrations is often performed by measuring light absorption in UV-VIS spectrometers. There are a few challenges faced in this measurement method. In UV-VIS ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

You want fluffy, perfect rice without the guesswork. Stop treating rice like pasta—boiling and draining often strips starch ...
