Speech Title: Directionally catalytic hydroconversion of organic matter in coals under mild conditions
Abstract: Directionally catalytic hydroconversion of organic matter in coals under mild conditions is an ultimate approach for the efficient utilization of coal resources. Its pilot step is directionally catalytic hydrocracking of organic matter in coals, i.e., using active hydrogen species (especially H+ and H-) produced by the interaction of highly active catalysts with H2 to cleave bridged bonds connecting aromatic rings and side chains on the aromatic rings as completely as possible so that non-substituted aromatic mixture with simple composition can be obtained and value-added pure non-substituted aromatics can be obtained by subsequent separation.

Speech Title: Recycled Nanomaterials for Energy Storage (Supercapacitors) applications
Abstract: The electrochemical performance of MnO2 nanoflowers recovered from spent Zn‒C battery was studied by cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy. For comparison, MnO2 has been prepared by electrodeposition (galvanostatic and potentiostatic) of KMnO4. In an effort to utilize recovered MnO2 nanoflowers as energy storage supercapacitor, it is crucial to understand their structure and electrochemical performance. MnO2 deposited by galvanostatic condition showed smaller particle size, less compact layered structure, wider bandgap, and higher specific capacitance in comparison to potentiostatic deposition. Charge‒discharge results showed that the MnO2 possesses a good capacitive behavior (207, 195, and 188 F g-1, respectively at 0.5 A g-1, for galvanostatic and recycled and potentiostatic MnO2, respectively). The prepared MnO2 materials have been widely used in supercapacitor application, and our findings show that MnO2 recovered from batteries and obtained by galvanostatic are more suitable to be applied as supercapacitor electrode.

Speech Title: NMR Spectroscopy for the Analysis of Fermented Foods
Abstract: Fermented foods are very complex in composition and very much prune to contamination. Discrimination of fermented foods is a challenging with respect to their process of manufacture, raw materials and geographical origin. In this talk, the challenges for studying metabolic profiles of fermented foods by NMR spectroscopy will be presented. It will include the optimization of NMR based metabolomic methodologies, characterization of fermented foods and exploring their patterns, raw materials, process of manufacture and tracing of raw materials and origin. The presenter will also discuss the data pre-processing including baseline and phase correction and exploratory data analysis by combination of multivariate methods and NMR analysis. At the end the talk will also focus on the potentiality and usefulness of NMR based metabolomics for the characterization of fermented foods.
This talk will be of interest for the scientists and students involved in NMR based metabolomics for food analysis
