Thermal maturity assessment of some Egyptian crude oils as implication from naphthalene, phenanthrene and alkyl substituents

Egyptian Journal of Petroleum, 2021
The study is paying attention to the variation of the comparative abundance of naphthalenes, phenanthrenes of aromatic fractions separated from seven different Egyptian crude oils, and were studied by GC–MS to assess the thermal maturity and recognize ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

Advanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

Replica Plating Method for Estimating Phenanthrene-Utilizing and Phenanthrene-Cometabolizing Microorganisms [PDF]

Applied and Environmental Microbiology, 1983
A replica plating method was developed for detecting and enumerating phenanthrene-degrading microorganisms. The method is designed to discriminate between aquatic organisms that utilize phenanthrene as the sole carbon and energy source and organisms that cometabolize phenanthrene.

Reimagining o‐Carborane‐Based Fluorophores: Charge‐Transfer from Boron Substituents Triggers Aggregation‐ and Crystallization‐Induced Emission

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
This work reports, for the first time, aggregation‐ or crystallization‐induced emission in boron‐substituted carboranes, which was driven by photoinduced charge‐transfer from fluorophore attached via boron vertices. The emission properties can be tuned by varying the substituents, expanding design strategies for luminescent materials.
