A Bilayer Micro/Nanostructured Water‐Based Paint With Effective Thermal Insulating and Reflective Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
The design, optimization and characterization of a new bilayer painting system is presented. The underlying layer is engineered to provide exceptional thermal insulation through the synergistic effect of hollow perlite microspheres and micrometer‐sized cellulose particles. The external painting layer is designed to induce the formation of a homogeneous

High‐throughput Photocatalytic Reactor With in Operando Characterisation for Fast Screening of Materials for the Photodegradation of Water‐Borne Pollutants

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel fast‐screening photocatalytic reactor system (FaS‐PhoReS) using terrestrial sunlight is able to measure the in operando photodegradation of 32 samples at once, and does not suffer from the common problem of sample evaporation. Four photostable 12 dyes are used to investigate the photocatalytic performance of TiO2 and ZnO samples in both film ...

3D Printing and Biocementation of Hierarchical Porous Ceramics

open access: yesAdvanced Materials Technologies, Volume 10, Issue 7, April 4, 2025.
Hierarchical porous ceramics are produced at room temperature via 3D printing and bacteria‐driven biocementation. By using ureolytic bacteria to precipitate calcium carbonate between ceramic hollow spheres, the reported manufacturing process offers a sustainable alternative to traditional energy‐intensive approaches and leads to monoliths with higher ...
