The recent work performed by a team of INAC researchers could widen the range of photocatalysts for chemical synthesis. This work evidenced the efficiency of core-shell CdSe-ZnS quantum dots as redox photocatalysts. These nanocrystals can be activated by visible light in water solution. Another ... More »

In oleaginous seeds, the energy reserves are mainly triacylglycerols that are liquid lipids contained inside micrometric vesicles, called oil bodies (OB). Seeds are of first importance for human and animal feeds, for biofuels sources and their economic weight is far from being negligible. Therefore ... More »

Owing to an innovative sample preparation method labelled “matrix-free”, the powerful structural characterization technique of two-dimensional NMR carbon-carbon correlation spectroscopy, up to now reserved to isotopically carbon-13 enriched materials, is made accessible to natural ... More »

Mesoporous alumina (Al2O3) presents itself as a technologically important material due to its high surface area and catalytic properties. However, the characterization of this material remains elusive to various techniques. Using a hyperpolarization technique called dynamic nuclear polarization ... More »

In the 1990 years several groups tried to design purely organic polymers with collective magnetic properties (ideally with a ferromagnetic transition). The best result in this field was reported in 2001 by Rajca et al, who obtained a high-spin (S~5000) polymer exhibiting some of the properties of ... More »

The cell wall of bacteria is composed of several biopolymers building a shell around the cell, which allows recognition and adhesion to hosts, as well as regulation of other important cellular functions. A better understanding of the complex cell wall structure and interactions may help ... More »

LiFePO4-based material is considered as one of the most promising for positive electrodes in commercial lithium-ion batteries. However, the reasons for the decrease in their electrical storage specifications during electrochemical cycles are not fully understood. Besides the structural and chemical ... More »

We have used high-resolution solid-State 13C NMR to better understand and optimize the conservation process of archaeological waterlogged woods by polyethylene glycol (PEG) impregnation via the  study of the molecular interactions between PEG and residual celluloses. We showed that the PEG ... More »

In a molecule bearing several unpaired local spins, one of the pertinent parameters that govern its magnetic properties is the magnetic exchange interaction constant J that describes the way spins “talk to each other” through the atoms connecting them (bridges). The RM laboratory, by ... More »
