Folic Acid With Fluorene: A Complexation Study by UV and FTIR Spectroscopies

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
The complexation between folic acid and a typical polyaromatic hydrocarbon, fluorene, was investigated using FTIR and UV spectra. Appearance of a new IR band at 2401cm−1 demonstrates that NH2–C=N moiety on pterin ring in folic acid is protonated ...

Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, EarlyView.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

ChemistryEurope, EarlyView.
A one‐pot protocol to synthesize reactive benzyl‐ and allyl‐halide‐substituted (dihydro)naphthalenes from 2,3‐aryl‐1,3‐butadiene substrates and halogenated alkanes has been developed, using [Cp*RuCl(PPh3)2] as the catalyst. Mechanistic studies revealed an atom transfer radical addition and radical benzannulation sequence, followed by HCl elimination ...

Modelling and simulation of hydrogen production via natural gas plasma pyrolysis

The Canadian Journal of Chemical Engineering, EarlyView.
Methane pyrolysis simulation model. Abstract Plasma pyrolysis is a cutting‐edge technology that produces hydrogen and solid carbon from methane without emitting carbon dioxide. In this study, we developed a process simulation model in Aspen HYSYS to analyze the behaviour of this technology at the commercial scale.
