Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

open access: yesAdvanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Type-Based Termination, Inflationary Fixed-Points, and Mixed Inductive-Coinductive Types

open access: yes, 2012
Type systems certify program properties in a compositional way. From a bigger program one can abstract out a part and certify the properties of the resulting abstract program by just using the type of the part that was abstracted away.

Synergistic Fluorine and Cyanide Co‐Modification to Reinforce Photoinduced Excitons Formation and Transfer for Efficient CO2 Photoreduction

open access: yesAdvanced Functional Materials, EarlyView.
An advanced F‐doped and ─CN group co‐modified FCCN is developed. Due to the synergistic effects of co‐modification in promoting photogenerated exciton generation, enhancing charge kinetics, expanding active interfacial areas, and optimizing CO2 interfacial reactions, the FCCN photocatalyst demonstrates excellent catalytic performance and high ...

The large scale impact of offshore wind farm structures on pelagic primary productivity in the southern North Sea

open access: yes, 2018
The increasing demand for renewable energy is projected to result in a 40-fold increase in offshore wind electricity in the European Union by 2030. Despite a great number of local impact studies for selected marine populations, the regional ecosystem ...

Enhancing and Stabilizing Hydrogen Catalysis Through [NiFe]‐Hydrogenase Immobilization Within Macroporous Covalent Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
[NiFe]‐hydrogenases efficiently catalyze hydrogen conversion, but their instability limits biotechnological applications. Here it is shown that encapsulating hydrogenase into hierarchical COFs with macro‐ and micropores and functionalized with sulfonic or carboxylic acid groups improves enzyme stability and electron transfer to electrodes.
