Single‐Step Conversion of Metal Impurities in CNTs to Electroactive Metallic Nitride Nanoclusters for Electrochemical CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step, low‐temperature co‐pyrolysis process removes encapsulated seed metal NPs (10–50 nm) from CNTs, redistributing them as surface‐anchored metal and metal–nitride NCs (1–1.5 nm). Herein, Ni3N NCs achieve an ultra‐low onset overpotential for CO2 reduction to CO with >98% Faradaic efficiency across 100–700 mA cm−2.

The spectrum of neutralizing and non-neutralizing anti-FVIII antibodies in a nationwide cohort of 788 persons with hemophilia A

open access: yesFrontiers in Immunology
ObjectivesAnti-factor VIII (FVIII) antibodies have been reported to exhibit both neutralizing and non-neutralizing characteristics. This is the first study investigating the full spectrum of FVIII-specific antibodies, including non-neutralizing ...

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Direct Laser Ablation of 2D Material Films for Fabricating Multi‐Functional Flexible and Transparent Devices

open access: yesAdvanced Functional Materials, EarlyView.
A scalable method for direct laser patterning of 2D films on transparent substrates like polycarbonate and glass is presented. This technique eliminates the need for photolithography and solvents, enabling the fabrication of functional devices like strain gauges, supercapacitors, and photodetector arrays.
