Investigation of Lactones as Innovative Bio-Sourced Phase Change Materials for Latent Heat Storage

open access: yesMolecules, 2019
In the presented work, five bio-based and bio-degradable cyclic esters, i.e. lactones, have been investigated as possible phase change materials for applications in latent heat storage systems. Commercial natural lactones such as ε-caprolactone and &

Use of metal catalysts bearing Schiff base macrocycles for the ring opening polymerization (ROP) of cyclic esters [PDF]

open access: yes, 2017
© 2017 by the authors. Schiff base macrocycles are emerging as useful scaffolds for binding two or more catalytic metals in close proximity. Such coordination chemistry allows for the evaluation of potentially beneficial catalytic cooperative effects. In

Morphology–acidity synergy in ZSM-5 for selective para-xylene synthesis via CO2/H2-mediated toluene methylation

open access: yesJournal of CO2 Utilization
CO2/H2-mediated toluene methylation over metal oxide–zeolite bifunctional catalyst offers a sustainable route for para-xylene (PX) synthesis, yet how zeolite morphology and acidity synergistically govern this coupled process remains unclear.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
