ABSTRACT: Carotenoids are a group of natural pigments that are isolated from plants and are known for their great importance in maintaining human health. Beta-carotene is an organic compound, from ...

A team from the United State’s Lawrence Livermore National Laboratory (LLNL), Stanford University and the University of Pennsylvania, has developed a novel wet chemical etching process that modifies ...

In a study published on ScienceAdvances, US researchers from Stanford Nano Shared Facilities (SNSF) and Lawrence Livermore National Laboratory (LLNL), with support from the National Science Foundation ...

In scientific experiments and research, determining the concentration of a solution is crucial for obtaining accurate results. One method of doing this is through measuring the absorbance of the ...

Molar absorptivity, also known as molar absorptivity coefficient or molar absorption coefficient, is a fundamental parameter in spectroscopy that quantifies the absorption of light by a molecule. It ...

Abstract: Absorptivity control is a very desired feature in many RF applications as it allows enhancing electromagnetic performances such as antenna radiation patterns and reducing radar cross section ...
