Our overarching goals have been the definition of sustainable and green chemistry and the development of appropriate metrics. Although sustainable chemistry is fundamentally different from green chemistry, there are some overlaps and each has pieces of the other. This could be demonstrated by a yin and yang (陰陽), one of the key principles of Ancient Chinese philosophy to manage seemingly opposite forces and achieve harmony.  Thus, the integration of sustainable chemistry and green chemistry could lead to sustainable and green chemistry – More …

Biomass Conversion

The increased use of biomass-based resources for the production of aviation fuels, basic and intermediate chemicals, and commodity plastics could slow the depletion of fossil reserves. In addition, less carbon dioxide will be released to the atmosphere and consequently transferred to the seas and oceans resulting in slower climate change and acidification in aqueous environments. The valorization of agricultural residues and food wastes has been also investigated and their sustainability indexes has been calculated – More …


Fluorous_pictureFluorous chemistry

The original fluorous biphasic concept was designed in 1992, which was based on the temperature regulated separation of perfluorinated alkanes from common organic solvents by attaching fluorous ponytails, mostly long-chain C6-C12-perfluoroalkyl groups,  to reagents and catalysts in appropriate numbers. We have been focusing on the phase-out of the long-chain perfluoroalkyl containing substances due to their adverse environmental and health effects.  The combined use of short-chain perfluoroalkyl groups could preserve the hydrophobic properties and lower their toxicity. Therefore, a wide range of novel fluorous compounds with short-chain perfluoroalkyl groups, including iodides, alcohols, thiols, silanes, bipyridines, and pincer ligands have been synthesized and characterized – More …


insituIn situ spectroscopy

We have been using in-situ IR and NMR spectroscopic probes to provide molecular level information of chemical reactions under a specific set of a reaction conditions in real time. In situ spectroscopy allows the determination of the concentration of detectable species (substrates, products, side-products, catalyst precursors, key intermediates, etc.) and can be used for kinetic and thermodynamic studies – More …


Microplastics

Microplastics have become a global pollution problem, especially in aqueous environments. We have just started investigating microplastics collected from the Danube river. After their separation, we will use scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), attenuated total reflectance infrared spectroscopy (ATR-FTIR), attenuated total reflectance Raman spectroscopy, and solid state NMR for their characterization – More …
