Advanced Robotics Research, EarlyView.Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.

Polymer‐Grafted Cu(II) Metal–Organic Polyhedra as Scalable, Melt‐Processable Porous Materials
Advanced Science, EarlyView.The use of a direct synthetic route to obtain polymer‐grafted Cu(II)‐based metal–organic polyhedra gives rise to a low‐cost and scalable cage. This material combines low‐temperature melting, achieving phase changes while preserving cage integrity, and high CO2 uptake exceeding 0.6 mmol g−1.

Batteries &Supercaps, Volume 8, Issue 3, March 2025.This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.
