A Proton Selective Carbon Nitride Layer for High Durability Fuel Cells

Advanced Functional Materials, Volume 35, Issue 13, March 25, 2025.
A Langmuir‐based approach is used to engineer a centimetre‐scale monolayer film of tessellated 2D graphitic carbon nitride sheets (Polytriazine Imide (PTI)). Optimal pore geometry and functionalization result in a proton‐selective hydrophilic lattice. Integrating the PTI nanolayer at the PEM‐cathode interface of a fuel cell provides improved nanoscale ...

Perfect Ultraviolet Absorbers via Disordered Polarizonic Metasurfaces for Multiband Camouflage and Stealth Technologies

Advanced Functional Materials, Volume 35, Issue 14, April 3, 2025.
An ultrathin polarizonic metasurface achieves multiband camouflage and stealth with near‐perfect ultraviolet (UV) absorption, visible light blending, and infrared signature masking. Leveraging earth‐abundant materials, this design creates a reflective color palette through polarizonic effects, integrating transparent and non‐plasmonic materials.

Atomically Flat Dielectric Patterns for Bandgap Engineering and Lateral Junction Formation in MoSe2 Monolayers

Advanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
This study presents a method to create atomically flat dielectric patterns of SiO2 and AlOx for MoSe2 monolayers, forming lateral heterojunctions with minimal strain. The dielectric pattern modulates excitonic properties, contact potential, and carrier dynamics, demonstrating a tunable approach for enhancing the optoelectronic properties of 2D ...

Mode evolution of TAE due to alpha particles and synergy with ripple loss in CFETR

Nuclear Fusion
The alpha particle should have good confinement when there are instabilities and toroidal field ripples in fusion devices. With the alpha particle slowing down distribution generated by TRANSP/NUBEAM, the Alfven eigenfunction calculated by NOVA/NOVA-K ...

Selective Reduction Laser Sintering: A New Strategy for NO2 Gas Detection Based on In2O3 Nanoparticles

Advanced Functional Materials, EarlyView.
This research utilizes selective reduction laser sintering (SRLS) to engineer In2O3 NPs for flexible NO2 sensors. The introduction of oxygen vacancy defects enhances sensor performance, offering excellent responsiveness, rapid response/recovery, superior selectivity, low detection limit, and long‐term stability.

Perturbations of the scattering resonances of an open cavity by small particles. Part II: The transverse electric polarization case [PDF]

arXiv, 2018
This paper is concerned with the scattering resonances of open cavities. It is a follow-up of "Perturbation of the scattering resonances of an open cavity by small particles. Part I" where the transverse magnetic polarization was assumed. In that case, using the method of matched asymptotic expansions, the leading-order term in the shifts of scattering

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

Advanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

Advanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

Enhanced Performance and Durability of Zinc–Air Batteries Utilizing W‐Doped Cobalt Pentlandite Catalysts

Advanced Functional Materials, EarlyView.
A W‐doped cobalt pentlandite electrocatalyst with sulfur vacancies is synthesized, guided by DFT calculations, which modifies the d‐band center, promoting oxygen intermediate desorption and lowering the *O generation energy barrier, thus enhancing catalytic activity.
