Predicting the UV–vis spectra of oxazine dyes
Beilstein Journal of Organic Chemistry, 2011 In the current work we have investigated the ability of time-dependent density functional theory (TD-DFT) to predict the absorption spectra of a series of oxazine dyes and the effect of solvent on the accuracy of these predictions.

Diclofenac analysis in natural waters using UV-visible absorption spectrometric method
Macedonian Journal of Chemistry and Chemical Engineering, 2023 In this work, we developed an UV-visible (UV-VIS) absorption spectrometric method for the quantification of sodium diclofenac in natural waters. Several UV-VIS absorption method parameters were optimized.

Remote Sensing Observation of New Particle Formation Events with a (UV, VIS) Polarization Lidar
Remote Sensing, 2019 Observations of new particle formation events in free troposphere are rather seldom and limited in time and space, mainly due to the complexity and the cost of the required on-board instrumentation for airplane field campaigns.

Indigo in the nanochannels of zeolite L : towards a new type of colorant [PDF]
, 2018 A host-guest based colorant was synthesized by intercalating indigo molecules into the nanochannels of zeolite L (ZL). Reductive washing thereby ensured the efficient and selective removal of non-intercalated indigo molecules.
