Current‐Limiting Control Strategies in Variable Capacitance Electrostatic Energy Harvesters

open access: yesAdvanced Intelligent Systems, EarlyView.
This work introduces control strategies for electrostatic energy harvesters that balance energy yield with current limitations. Two approaches are explored: traditional peak‐triggered controls, and newly developed quadrature controls, which use smooth voltage profiles.

Myoelectric Origami‐Based Soft Robotic Knee Exoskeleton to Enhance Sit‐to‐Stand Assistance in Elderly Populations

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a lightweight Miura‐origami soft knee exoskeleton powered by vacuum actuation and integrated with a multimodal physiological intent‐recognition system, providing real‐time assistance during sit‐to‐stand movement to reduce muscle effort and improve user comfort.

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature

open access: yesAngewandte Chemie International Edition, EarlyView.
Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

Combined In‐Solution and On‐Surface Synthesis of a Fully Fused Cross‐Shaped Phthalocyanine Pentamer

open access: yesAngewandte Chemie International Edition, EarlyView.
A phthalocyanine (Pc) pentamer was obtained through the combination of in‐solution and on‐surface synthesis under ultra‐high vacuum conditions. The resulting Pc‐based nanostructure presents an exact 4:1 ratio of two different metal ions with precise positional control.
