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

open access: yesAdvanced 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.

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

open access: yesAdvanced 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.

Silicon-etalon fiber-optic temperature sensor [PDF]

open access: yes
A temperature sensor is described which consists of a silicon etalon that is sputtered directly onto the end of an optical fiber. A two-layer protective cap structure is used to improve the sensor's long-term stability.

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Fiber optic gas sensor [PDF]

open access: yes, 2010
A gas sensor includes an in-fiber resonant wavelength device provided in a fiber core at a first location. The fiber propagates a sensing light and a power light. A layer of a material is attached to the fiber at the first location.

Over 18% Efficiency from Halogen‐Free Solvent‐Processed Polymer Solar Cells Enabled by Asymmetric Small Molecule Acceptors with Fluoro‐Thienyl Extended Terminal

open access: yesAdvanced Functional Materials, EarlyView.
An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.
