Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Spectrophotometric determination of erbium using kojic acid dye in different rare earth concentrates

Egyptian Journal of Petroleum, 2018
A sensitive and selective spectrophotometric method was studied for the determination of erbium (Er) with kojic acid dye (koj) and cetylpyridinium chloride (CPC) as a cationic surfactant from Egyptian monazite and xenotime concentrates using third ...

Integrated Metallo‐Dielectric 3D Hotspots From High Refractive Index Nanodiamond‐Plasmonic Gold Cryosoret Nano‐Assemblies for Photonic Crystal Enhanced Fluorescence

Advanced Functional Materials, EarlyView.
This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Derivative Spectrophotometric Estimation of Ondansetron and Paracetamol

E-Journal of Chemistry, 2006
A simple and reproducible spectrophotometric method, requiring no prior separation, has been developed for the estimation of ondansetron and paracetamol in combined dosage form. First order derivative spectroscopy method is adopted to eliminate spectral

Photoresponsive Gas‐Permeable Membranes: Fundamentals, Innovations, and Prospects

Advanced Functional Materials, EarlyView.
Photoresponsive gas‐permeable membranes can be potentially used for smart packing, carbon capture, hydrogen purification, and optical gas valves due to their remote and non‐contact activation, precise spatial and temporal control, and reversible switching capabilities.
