The developing field of active, stimuli-responsive materials is in need for new dynamic architectures that may offer unprecedented chemomechanical switching mechanisms. Toward this goal, syntheses of polymerizable bipyridine ligands, bis(4-vinylbenzyl)[2,2′-bipyridine]-4,4′-dicarboxylate and N4,N4′-bis(4-vinylphenyl)-2,2′-bipyridine-4,4′-dicarboxamide, and a number of redox-active Ruthenium(II)...

Solid oxide fuel cells are able to convert fuels, including hydrocarbons, to electricity with an unbeatable efficiency even for small systems. One of the main limitations for long-term utilization is the reduction-oxidation cycling (RedOx cycles) of the nickel-based anodes. This paper will review the effects and parameters influencing RedOx cycles of the Ni-ceramic anode. Second, solutions for ...

Over 30 million ton of poly(ethylene terephthalate) (PET) is produced each year and no more than 60% all PET bottles are reclaimed for recycling due to material property deteriorations during the mechanical process. Herein, a sustainable approach proposed produce redox-active nanoparticles via chemical upcycling waste application in energy storage. Redox-active sizes lower 100 nm were prepared ...

Astrocytes are critical for neuronal redox homeostasis providing them with cysteine needed for glutathione synthesis. In this study, we demonstrate that the astrocytic redox response signature provoked by amyloid beta (Aβ) is distinct from that of a general oxidant (tertiary-butylhydroperoxide [t-BuOOH]). Acute Aβ treatment increased cystathionine β-synthase (CBS) levels and enhanced transsulfu...

The paper presents the results of experiments on reduction copper oxides formed during heat treatment metallic samples in air. necessary condition is presence a muffle made material with higher electron affinity (lower standard electrode potential) compared to copper. Replacing nitrogen composition atmosphere an equal proportion argon does not change observed redox pattern. Our indicate electro...

Blunted beta-adrenergic inotropism in stunned myocardium is restored by pharmacological (N-acetylcysteine) and metabolic (pyruvate) antioxidants. The ketone body acetoacetate is a natural myocardial fuel and antioxidant that improves contractile function of prooxidant-injured myocardium. The impact of acetoacetate on postischemic cardiac function and beta-adrenergic signaling has never been rep...

Precise matching of energy supply with demand requires delicately balanced control of the enzymes involved in substrate metabolism. In response to a change in substrate supply, the nonlinear properties of metabolic control may induce complex dynamic behavior. Using confocal imaging of flavoprotein redox potential and mitochondrial membrane potential, we show that substrate deprivation leads to ...

While numerous reference electrodes suitable for aqueous electrolytes exist, there is no well-defined standard non-aqueous electrolytes. Furthermore, are often large and do not meet the size requirements small cells. In this work, we present a simple method fabricating stable 3D-printed micro-reference electrodes. The prints made from polyvinylidene fluoride, which chemically inert in strong ac...
