Synthesis and Shaping of Functionalized Microporous Materials for the Catalytic Transformation of Monosaccharides, Synthèse et mise en forme de matériaux microporeux fonctionnalisés pour la transformation catalytique des monosaccharides

Bakytzhan Yeskendir

Biomass valorization is a process of converting different types of plants and residual wastes into high-value chemicals and energies carriers. Zeolites and Metal-Organic Frameworks (MOFs) have attracted a great deal of interest as solid catalysts owing to their developed chemical properties as well…, La valorisation de la biomasse inclus les processus de conversion de différents types de plantes et de déchets végétaux en produits chimiques et biocarburants à haute valeur ajoutée. Les zéolithes et une classe récente de matériaux appelés Metal-Organic Frameworks (MOFs) ont suscité un grand…

Sequential construction and dimension reduction of Gaussian processes under constraints

François Bachoc, Andrés F. López-Lopera, Olivier Roustant

Accounting for inequality constraints, such as boundedness, monotonicity or convexity, is challenging when modeling costly-to-evaluate black box functions. In this regard, finite-dimensional Gaussian process (GP) regression models bring a valuable solution, as they guarantee that the inequality…
