Kern‑Schale: Versiegelung nanoporöser Partikel mit semipermeablen Kohlenstoffschichten befreit Hartkohlenstoffanoden von ihrem Dilemma

Angewandte Chemie, EarlyView.
Eine Kern‐Schale‐Strategie wird vorgestellt, um die hohen Verluste nichtgraphitischer Hartkohlenstoffanoden zu überwinden. Aktivkohle wird durch Gasphasenabscheidung mit einer semipermeable Kohlenstoffschicht versiegelt, wodurch die SEI‐Bildung und Natriumspeicherung räumlich getrennt werden.

Regulating Solvent Co‐Intercalation in Bi‐Layered Vanadium Oxides for Zinc Batteries by Nanoconfinement Chemistry

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The feasibility of regulating solvent co‐intercalation by electrode nanoconfinement design is demonstrated. Through decreasing interlayer hydration and introducing organic molecules with reduced lone electron‐pair density, the interlayer solvo‐philicity of bi‐layered vanadium oxides is tuned.

Mechanistic Elucidation of Nanomaterial-Enhanced First-Generation Biosensors Using Probe Voltammetry of an Enzymatic Reaction

Biosensors, 2023
The incorporation of nanomaterials (NMs) into biosensing schemes is a well-established strategy for gaining signal enhancement. With electrochemical biosensors, the enhanced performance achieved from using NMs is often attributed to the specific physical

Core‐Shell: Resolving the Dilemma of Hard Carbon Anodes by Sealing Nanoporous Particles With Semi‐Permeable Coatings

Angewandte Chemie International Edition, EarlyView.
A core–shell strategy is presented to overcome the high first‐cycle losses of non‐graphitic hard carbon anodes. Activated carbon is sealed by gas‐phase carbon deposition to create semi‐permeable shells that spatially separate SEI formation from Na storage in a retained nanoporous core. The resulting anode delivers 400 ± 24 mAh g−1 with an ICE of 82 ± 2%

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

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.
