Development of non‐destructive analytical strategies based on Raman spectroscopy and complementary techniques for Mars Sample Return tested on Northwest Africa 1950 Martian meteorite

Journal of Raman Spectroscopy, Volume 53, Issue 12, Page 2068-2085, December 2022., 2022
A non‐destructive analytical methodology, based on Raman microscopy (single point and imaging), micro‐energy dispersive X‐ray fluorescence (μED‐XRF) imaging analysis, and scanning electron microscopy coupled to energy dispersive spectroscopy (SEM‐EDS), is suggested for a first analytical characterization for the Martian samples that will be taken to ...

Digestate from small‐scale biogas plants in central Vietnam produced under mesophilic conditions: friend or foe for local farmers?

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study evaluates the suitability of digestate from small mesophilic biogas plants in central Vietnam for agricultural application. Digestate samples were collected from 85 farms and analyzed for microbial contamination and elemental composition.

Creating a database of biobased hydrogen production: country‐based evaluations and comparative analysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Hydrogen is increasingly recognized as a crucial element in a sustainable future, providing a variety of solutions to address the climate crisis. Its importance is emphasized by its adaptability, high energy content, and capacity to decarbonize a number of industries, including steel production, the chemical sector (e.g., ammonia and methanol ...

Cross‐Linking of Biobased Monofunctional Furan Epoxy Monomer by Two Steps Process, UV Irradiation and Thermal Treatment

Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023
Two‐steps process is demonstrated to cross‐link a monofunctional furan‐based epoxy monomer derived from furfuryl alcohol. The cationic UV‐irradiation allows to form linear polymer chains while the thermal treatment creates the cross‐links between the different chains.

Isotopomer Fractionation in the UV Photolysis of N_2O: 3. 3D Ab Initio Surfaces and Anharmonic Effects [PDF]

, 2010
The wavelength-dependent isotopic fractionation of N_2O is calculated, extending our previous work, Parts 1 and 2, in several aspects: (1) the fully three-dimensional ab initio electronic potential and transition dipole moment surfaces of S. Nanbu and M.

Light‐Driven CO2 Reduction Catalysis with Organic Thermally Activated Delayed Fluorescence (TADF) Sensitizers

ChemCatChem, EarlyView.
A critical analysis is given of the recent experimental results involving the use of thermally‐activated delayed fluorescence (TADF) dyes as photosensitizers for the light‐driven CO2 reduction reaction. Both positive aspects and open questions are highlighted.

Optimization of Active Sites in TiO2–Cu Photocatalysts for H2 Generation via Cellulose Photo‐Reforming

ChemCatChem, EarlyView.
Three series of titania–Cu photocatalysts have been prepared and tested for hydrogen generation by cellulose photo‐reforming. Copper was incorporated, by impregnation, in P25 (a) and in hydrothermally synthesized TiO2 (b), and also by a one‐pot hydrothermal synthesis (c).
