Revealing the Importance of Phase and Morphology Dynamics in the Excellent Long‐Term Cycling Stability of Flower‐Like BiOCl Sodium‐Ion Anodes

Small Structures, Volume 6, Issue 12, December 2025.
Bismuth oxychloride micro‐flowers were investigated to reveal phase and morphology evolution during cycling. An electrochemical activation protocol was developed to expedite their transformation to a nanoporous sponge‐like structure. Bismuth oxychloride (BiOCl) is a low‐cost, nontoxic anode material for sodium‐ion batteries (SIBs), offering a ...

Mechanical nano-structuration of a C45 steel under repeated normal impacts

IOP Conference Series: Materials Science and Engineering, 2014
Under repeated impact loadings that are encountered during peening process, surface mechanical attrition treatment or erosive wear, metals undergo severe plastic deformation which may lead to a local refinement of their microstructure in the near-surface.

Physical structural assessment of a segmented concrete shell building floor prototype

Structural Concrete, Volume 26, Issue 6, Page 8419-8436, December 2025.
Abstract To reduce the significant environmental impact of the construction industry, building floors designed as concrete shells that work mainly in compression and that are segmented for prefabrication and disassembly offer a promising alternative to reinforced thick flat slabs.

Effects of Surface Coatings on the Joint Formation During Magnetic Pulse Welding in Tube-to-Cylinder Configuration [PDF]

, 2016
Magnetic Pulse Welding (MPW) is a joining technique favorable for the generation of strong atomic bonded areas between different metals, e.g. aluminum and steel.

The influence of casting position and depth of concrete pour on bond strength

Structural Concrete, Volume 26, Issue 6, Page 7240-7255, December 2025.
Abstract Bond strength of steel bars cast near the top of a concrete pour may be lower than that of bars cast close to the bottom due to an increase in water content, to consolidation of fluid concrete below the bar, or to both. Current design codes typically require increases of 20%–40% in anchorage and lap lengths in “poor” bond conditions to allow ...

Tension-stiffening behaviour of reinforced concrete ties of various strength classes [PDF]

, 2015
A new law of tension-stiffening for reinforced concrete (RC) ties is proposed in the present study. It is based on the test data of 11 experimental programs of RC elements of various strength classes reported in the literature.

What Can We Learn Four Years On? A Multi‐Centre Service Evaluation Exploring Symptoms, Functional Impact, Recovery and Care Pathways in Long Covid

Health Expectations, Volume 28, Issue 6, December 2025.
ABSTRACT Background Long Covid (LC) is associated with long‐term health impacts that require ongoing support from healthcare services. We aimed to gain insights into patients' perceptions of their ongoing symptoms of LC, the effect on daily living and vocation, perceptions of what helps with LC recovery, as well as LC care pathways and ongoing care ...

The Influence of Variable Plasma Welding Parameters on Weld Geometry, Dilution Factor, and Microhardness

Applied Sciences
Weld surfacing is the process of applying a layer of metal to the surface of metal objects by simultaneously melting the substrate. As a result of this process, the metal content of the padding weld can be as high as several tens of percents.

Bond characterization between concrete substrate and repairing SFRC using pull-off testing [PDF]

, 2005
In the last years, an emerging repair and strengthening technique for concrete slabs has been used, consisting of applying a thin layer of steel fibre reinforced concrete(SFRC) onto the slabs.
