Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Impact of the T296S mutation in P450 GcoA for aryl-O-demethylation: a QM/MM study

Frontiers in Chemistry
Lignin, a complex plant cell wall component, holds promise as a renewable aromatic carbon feedstock. p-Vanillin is a key product of lignin depolymerization and a precursor of protocatechuic acid (PCA) that has tremendous potential for biofuel production.

The Case of H$_2$C$_3$O Isomers, Revisited: Solving the Mystery of the Missing Propadienone

, 2019
To date, two isomers of H$_2$C$_3$O have been detected, namely, propynal (HCCCHO) and cylclopropenone (c-H$_2$C$_3$O). A third, propadienone (CH$_2$CCO), has thus far eluded observers despite the fact that it is the lowest in energy of the three.

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

Advanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Mixed‐Dimensional 0D‐DNA‐2D Heterostructures Beyond van der Waals: A DNA‐Templated Strategy for Optoelectronic Tunability

Advanced Functional Materials, EarlyView.
A two‐step DNA metallization process is presented for the modular assembly of metal sulfide nanoparticles (NPs) on MoS2, with nanoscale control over their separation and ability to concomitantly assemble different kind of NPs. This allowed to tailor the photoinduced electrical response of phototransistors to different wavelengths, according to the ...

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

Advanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings

Advanced Functional Materials, EarlyView.
A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings

Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

Advanced Functional Materials, EarlyView.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.
