Fluorescence Quenching-Based Mechanism for Determination of Hypochlorite by Coumarin-Derived Sensors

International Journal of Molecular Sciences, 2019
A fluorescence quenching-based mechanism for the determination of hypochlorite was proposed based on spectroscopic and chromatographic studies on the hypochlorite-sensing potency of three structurally similar and highly fluorescent coumarins. The mode of

Mechanistic Insights Into Proton and Oxygen Transport Through Ultrathin Amorphous Al2O3 and Al2O3‐SiO2 Electrocatalyst Overlayers

Advanced Materials Interfaces, EarlyView.
Ultrathin amorphous alumina electrocatalyst overlayers block oxygen reduction while cathodic‐driven structural relaxation accelerates proton transport over time. By contrast, ultrathin aluminosilicate coatings allow proton permeation but cannot suppress oxygen.

Oxidized LDL bind to nonproteoglycan components of smooth muscle extracellular matrices

Journal of Lipid Research, 2001
Arterial wall lipid retention is believed to be due primarily to ionic interactions between lipoproteins and proteoglycans. Thus, oxidized low density lipoproteins (LDL), with decreased positive charge relative to native LDL, should have decreased ...

Direct Seawater Electrolysis with Stabilized High‐Performance NiCr Anodes

Advanced Materials Interfaces, EarlyView.
An assembly combining a highly active NiFe layered double hydroxyde electrocatalyst and a NiCr foam anode shows high corrosion resistance during alkaline seawater electrolysis (ASE), minimal Cr leaching in the electrolyte, and long‐term efficiency. An electrolyzer comprising the so‐prepared anode and a cathode derivatized with NiMoO4 achieves overall ...

Efficacy of chemical disinfectants for the containment of the salamander chytrid fungus Batrachochytrium salamandrivorans [PDF]

, 2017
The recently emerged chytrid fungus Batrachochytrium salamandrivorans (Bsal) causes European salamander declines. Proper hygiene protocols including disinfection procedures are crucial to prevent disease transmission.

Long‐Term Study of Optical Nanoparticles Doped With Yb3+/Er3+ and Transition Metal Ions and their Real Application for Imaging and Temperature Sensing on Triticum Aestivum L.

Advanced Optical Materials, EarlyView.
This work shows a study on SrF2:Yb3+, Er3+ water colloid, additionally doped with transition metals (Sc3+ or Zn2+) to enhance observed emission, tested during 22 weeks of storage in ambient conditions. Due to high stability, excellent optical properties achieved under 975 nm excitation, and negligible phytotoxicity, the nanoparticles are applied for ...

Hosts and Commensal Bacteria Synergistically Antagonize Opportunistic Pathogens at the Single‐Cell Resolution

Advanced Science, EarlyView.
In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...
