Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

Advanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

Advanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Fourier Transform Infrared Spectroscopy of the Animal Tissues

, 2021
Animal tissues are extensively used as scaffolds for tissue engineering and regenerative therapies. They are typically subjected to decellularization process to obtain a cell-free extracellular matrix (ECM) scaffolds. It is important to identify chemical structure of the ECM scaffolds and Fourier transform infrared (FTIR) appears to be a technique of ...

Fano Resonances in Mid-Infrared Spectra of Single-Walled Carbon Nanotubes

, 2012
This work revisits the physics giving rise to the carbon nanotubes phonon bands in the mid- infrared. Our measurements of doped and undoped samples of single-walled carbon nanotubes in Fourier transform infrared spectroscopy show that the phonon bands ...

High‐Speed and Scalable Wet Spinning of Graphene/Liquid Crystalline Elastomer Composite Filaments

Advanced Functional Materials, EarlyView.
Polydomain filaments from graphene/liquid crystalline elastomer (LCE) composites are scalably‐manufactured by wet spinning across a wide range of diameters (≈137–1128 µm) at a speed up to 4500 m h−1 through a double diffusion coagulation mechanism, enabling fast actuation and optimized mechanical performance for broad applications.

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

Advanced Functional Materials, EarlyView.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.
