Rare‐Metal‐Free Redox‐Mediated Zn–Air Rechargeable Battery (ReZARB): A Redox‐Mediated Approach for Reducing Charging Overpotentials

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
A three‐electrode Zn–air/Zn–hydroquinone (HQ) electrochemical cell employing a rare‐metal‐free oxygen reduction reaction catalyst and HQ as a redox mediator in the electrolyte can realize a rechargeable battery with significantly reduced charge–discharge overpotential compared to conventional Zn–air battery systems.

A head-to-head comparison of polymer interaction with mucin from porcine stomach and bovine submaxillary glands

open access: yesScientific Reports
Native mucus is heterogeneous, displays high inter-individual variation and is prone to changes during harvesting and storage. To overcome the lack of reproducibility and availability of native mucus, commercially available purified mucins, porcine ...

Probing the Influence of Sulfur–Aromatic Interactions on the Electronic Structure of Gas‐Phase Peptides

open access: yesChemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
Just as fingerprints reveal identity, spectroscopic fingerprints reveal molecular secrets. In this article, we show parts of the unique fingerprint of the sulfur–aromatic interaction. By measuring how this force alters the electronic structure of gas‐phase peptides, we provide a fundamental understanding of interactions that give insights into the ...

Analysing the PGM protocol with Uppaal

open access: yes, 2004
Pragmatic General Multicast (PGM) is a reliable multicast protocol, designed to minimize both the probability of negative acknowledgement implosion and the load of the network due to the retransmission of lost packets.

Molecular identification and expression of the phosphoglucomutase (PGM) gene from the Pacific oyster Crassostrea gigas

open access: yes, 2006
International audiencePhosphoglucomutase is a key enzyme in glycolysis and has been widely studied in vertebrates and some invertebrates but no molecular information is available in marine invertebrates despite the importance of this marker in ecological

Electrodeposited MnCo and MnNiCo Spinels for Anion Exchange Membrane Direct Ammonia Fuel Cell Cathodes: An Alternative to Platinum

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
Electrodeposited MnCoOX and MnNiCoOX spinels on Ni foam are evaluated as binder‐free, platinum group metal‐free cathodes in direct ammonia fuel cells. MnCoOX matches and surpasses Pt in oxygen reduction performance while tolerating ammonia crossover, whereas Ni incorporation dilutes the active Co–Mn sites and degrades performance.

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells

open access: yesAdvanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Actuation of Cell Layers in Three Dimensions

open access: yesAdvanced Materials, Volume 38, Issue 34, 17 June 2026.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the
