Data-driven design of catalysts for sustainable applications

 Artificial intelligence is increasingly able to predict successfully new chemicals that possess a targeted functionality. The success of such materials discovery approaches is nonetheless contingent upon having the right data source to mine, and machine-learning approaches that suitably encode structure-function relationships that can be used to predict a lead materialā€¦

Insights into Polymerization through Chemical ImagingĀ 

The ability to simultaneously image physical and chemical changes inside of polymers in real time during catalytic polymerization would be far-reaching.  It would enable not only understanding of dynamic chemical and physical changes inside polymers with high spatiotemporal resolution, but also how these two features impact each other. Here, the developmentā€¦

PiFM – Deciphering the nano-world

PiFM shows itself as a powerful technique to provide visual and spectroscopical data of materials in nano-scale: from silica nano-spheres to the complex biomineralization of clams. The talk aims to introduce the technique and some of the equipment capabilities. Biography Arthur got his PhD in chemical-physics/spectroscopy from the University ofā€¦

Green Catalysis Examples and Insights from the Caribbean

Sustainable chemicals production and renewable feedstocks development are key components to mediating negative impacts of fossil fuels and related chemicals on the biosphere. Our research is focussed on green catalysis and sustainable chemicals for health and wellbeing in a research space that has not yet adopted sustainability as a driverā€¦

UsingĀ In SituĀ Vibrational Spectroscopy to Probe (Electro)Catalytic Interfaces

The combination of electrochemical methods with molecular spectroscopy can provide valuable information about chemical processes at electrode-electrolyte interfaces. In particular, Raman and infrared spectroscopies have been shown to yield unique mechanistic insights into chemical reactions at electrodes by enabling fingerprinting of surface species via identification of characteristic vibrational modes. These powerful toolsā€¦

Chemical Recycling of Commercial Poly(l-lactic acid) toĀ l-Lactide Using a High-Performance Sn(II)/Alcohol Catalyst System

Poly(l-lactic acid) (PLLA) is a leading commercial polymer produced from biomass, showing useful properties for plastics and fiber applications; after use, it is compostable. One area for improvement is postconsumer waste PLLA chemical recycling to monomer (CRM), i.e., the formation of l-lactide (l-LA) from waste plastic. This process is currently feasibleā€¦

Computational Advancement towards Efficient Catalytic Materials – Connecting a Few DotsĀ 

In this talk, I would like to present a two-fold research activity interconnected with a common string ā€œCatalysisā€. The first part would be dedicated to the fundamental mechanism for the solar irradiated water splitting in photocatalytic materials with the future prospect of Non-linear Poisson Boltzmann Solver development for the heterogenous catalytic mechanism.The relevant explorationā€¦
