This thematic project aims to rationalize, in molecular terms, the interactions between solutes and pure solvents or their binary mixtures and to apply this knowledge to optimize chemical processes of interest. Where possible, green solvents with low environmental impact will be employed, for example, water, esters of carbonic acid, and ionic liquids. The goals of this project include det…
The thermodynamic characterization of mixtures are crucial for understanding the interactions that occur therein. The isothermal titration calorimetry (ITC) is the method of choice to study chemical and biochemical interactions that involve change of enthalpy (most interactions are not thermos-neutral). Examples are reaction kinetics, association enzyme-substrate and formation of micellar…

Solvents affect reactions in several ways: It is the agent of heat-, and mass-transfer; It changes the free-energy of activation by solvating the reactants/transition states; It mediates proton transfers for acid-base catalyzed reactions, etc. Green chemistry principles dictate "atom efficiency", process safety, use of renewable starting materials, and production of biodegradable products…
It is intended in this project to study aspects of synthesis, properties and applications of tensoactives and derivatives of bio-polymers, in particular of cellulose. The first sub-project includes the following aspects of the chemistry of colloids: 1) synthesis of tensoactives which possess variable hydrophilic and hydrophobic groups, including "green" tensoactives based on 2-aminoglucos…
We are interested in investigating some aspects of the chemistry of surfactant solutions and polymers, including amphiphilic polymers. With regard to surfactant solutions both in water, and in organic solvents (reverse aggregates) we are interested in the following: (i) physico-chemical properties of aqueous micelles; (ii) properties of water in the interfacial regions of aqueous and reve…

This research project aims to study the dissolution of silk fibroin (FS) in binary mixtures of ionic liquids (LIs) and dimethylsulfoxide (DMSO), at fixed temperature and composition. The LIs to be investigated (eight in total) will be carboxylates based on imidazole, trimethyl(n-butyl)amine, and the superbase 1,8-diazobicyclo[5.4.0]-undec-7-ene (DBU). DMSO will be used as a co-solvent to …
Coordinated by Prof. Dr. Omar A. El Seoud-IQ-USPThis Thematic Project aims to rationalize, in molecular terms, the interactions between solutes and pure solvents or their binary mixtures and the application of this knowledge in the improvement of chemical processes of interest. Preferably green solvents with low environmental impact will be used; for example, water, esters of carbonic aci…
Processing of cellulose, the most abundant renewable terrestrial biopolymer, is still connected with some limitations. In particular the dissolution of this polysaccharide is not fully understood. Consequently, the available commercial products are produced by heterogeneous processes (solid cellulose/liquid bath). This makes the fabrication of speciality products difficult since tailored …
Cellulose dissolves in ionic liquids, ILs, allowing several applications (regeneration and transformation into derivatives). However, the cellulose solutions in some ILs are quite viscous or form gels, making difficult such applications. To avoid this issue, IL-molecular solvent (MS) or IL-water mixtures were being employed and this is the objective of this project. The aim is to choose…

Due to the presence of strong inter- and intramolecular hydrogen bonds between its hydroxyl groups, cellulose is a semi-crystalline biopolymer with highly ordered and amorphous regions. Disruption of these hydrogen bonds is important for the swelling, dissolution, and derivatization of this biopolymer. Most cellulose derivatives, in particular its esters and ethers, are prepared industria…
