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.

Multiphase Partitioning of Estrogens in a River Impacted by Feedlot Wastewater Discharge

open access: yesToxics
Estrogens in river systems can significantly impact aquatic ecosystems. This study aimed to investigate the multiphase partitioning of estrogens in Wulo Creek, Taiwan, which receives animal feedlot wastewater, to understand their distribution and ...

Colloid particle size‐dependent dispersivity

open access: yes, 2014
Laboratory and field studies have demonstrated that dispersion coefficients evaluated by fitting advection‐dispersion transport models to nonreactive tracer breakthrough curves do not adequately describe colloid transport under the same flow field ...

Measurement theory of a density profile of small colloids around a large colloid: Superposition of the radial distribution functions [PDF]

open access: yesarXiv, 2015
We propose a transform theory for calculating a density profile of small colloids around a large colloid from a force curve between the two-large colloids. In the colloid solution, there are many small colloids and two or several large colloids. The force curve between the two-large colloids can be measured by laser tweezers.

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.
