Acid catalysed transesterification of animal waste fat

Research in Agricultural Engineering, 2009
Rendering plant fat (RPF) was collected and different conditions were used for transesterification. The course of transesterification of RPF was compared with that of transesterification of lard under the same conditions.

A New Metal‐Ester Bonding Motif for the Synthesis of Hybrid Molecular Catalysts on Metal Oxide Supports Leads to Tunable Reactivity

Angewandte Chemie, EarlyView.
This work reports a new metal–ester bonding strategy for anchoring molecular catalysts to metal oxide supports, achieving exceptionally high surface loadings. Catalyst reactivity is predictably tuned by the support's properties, enabling control over electronic behavior and reaction pathways, thus opening new possibilities for designing highly ...

Fluorogenic Coupled Assays Reveal Catalytic Properties, Inhibition Constants and Cellular Location of Mucin‐Active Carbohydrate Sulfatases

Angewandte Chemie, EarlyView.
We report plate‐based coupled assays to rapidly and quantitatively determine the activity and selectivity of mucin‐active carbohydrate sulfatases. This fluorogenic assay further enables inhibitor identification and allows determination of (sub‐)cellular location. ABSTRACT Sulfated glycans play a central role in human health and influence cell signaling,

Rapid Stress Relaxation and Moderate Temperature of Malleability Enabled by the Synergy of Disulfide Metathesis and Carboxylate Transesterification in Epoxy Vitrimers.

ACS Macro Letters, 2019
Vitrimers make up a class of polymeric materials combining the advantages of thermosets and thermoplastics, because they can be reprocessed while being at the same time permanently cross-linked. However, a long heating duration or an elevated temperature
