Effects of Temperature Annealing on the Intrinsic Transport Mechanisms of Solution Processed Graphene Nanosheet Networks

open access: yesAdvanced Functional Materials, EarlyView.
Unravelling charge transport mechanisms in graphene nanosheet networks: by combining temperature‐dependent conductivity measurements with a Random Resistor Network model, this study identifies a transition from hopping‐dominated conduction to a band‐like transport mechanism.

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

open access: yesAdvanced 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.

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

open access: yesAdvanced 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
