Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Sonochemical Functionalization of Glass

open access: yesAdvanced Functional Materials, EarlyView.
A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

A highly efficient polysulfide mediator for lithium–sulfur batteries

open access: yesNature Communications, 2015
The lithium–sulfur battery is receiving intense interest because its theoretical energy density exceeds that of lithium-ion batteries at much lower cost, but practical applications are still hindered by capacity decay caused by the polysulfide shuttle ...

Improving the Capacity Retention of Poly(vinylphenothiazine) as Battery Electrode Material by Pore Size Engineering of Porous N‐Doped Carbon Nanospheres as Conductive Additive

open access: yesAdvanced Functional Materials, EarlyView.
By using (meso)porous N‐doped carbon nanospheres with tailored intraparticle porosity and constant particle size as conductive carbon in PVMPT‐based organic battery electrodes, the complete volume of the carbon is accessible for the immobilization of PVMPT, resulting in high accessible specific capacities while maintaining a good rate capability and ...

All‐Cellulose‐Based Photonic Glitters

open access: yesAdvanced Functional Materials, EarlyView.
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]

open access: yes, 1992
Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...
