Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems

Photochemistry and Photobiology, EarlyView.
Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

AMPK‐mediated prevention of vascular dysfunction with metformin: Experimental and population‐based evidence

British Journal of Pharmacology, Volume 183, Issue 17, Page 5389-5406, September 2026.
Angiotensin II induces vascular inflammation, senescence, extracellular matrix (ECM) degradation and endothelial dysfunction, thus impairing SK+/IK+ channel function and reducing endothelial‐dependent hyperpolarisation (EDH). Metformin activates AMPK, increasing SK+/IK+ channel function and restoring vasorelaxation.

Effect of niobium in the phase transformation and corrosion resistance of one austenitic-ferritic stainless steel [PDF]

Materials Research, 2014
Austenitic-ferritic stainless steels containing 0.2% and 0.5% niobium were evaluated with respect to the microstructures, microhardness, pitting potential resistance, electrochemical impedance and wearing tests. Niobium is an alphagenic element and has a

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...

The effect of alloying method on the structure and properties of sintered stainless steel

Archives of Metallurgy and Materials, 2017
Sintered duplex stainless steels (SDSSs) appear to be very interesting and promising materials that can be used in many industrial sectors. Ferrite improves material strength while austenite increases hardness and corrosion resistance.

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, Volume 97, Issue 8, Page 4363-4381, August 2026.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

Materials and Corrosion, Volume 77, Issue 7, Page 1094-1105, July 2026.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these
