Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

open access: yesAdvanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Influence of slotted casing treatment with surface roughness and dimples on the performance of an axial flow fan

open access: yesCogent Engineering
A numerical analysis is conducted to assess the impact of slotted casing treatments, dimples, and surface roughness on the performance of an axial flow fan. Five configurations were evaluated: baseline (without any flow control), axial slots, axial slots

Template‐Confined Synthesis of Shape‐Engineered Single‐Crystal Gold Microplates in Lithographically‐Defined Polymeric Patterns

open access: yesAdvanced Functional Materials, EarlyView.
Single‐crystal gold microplates are high‐performance nanomaterials with an impressive wafer‐based application space. Progress has, however, been tempered by an inability to exert synthetic control over microplate size, shape, and positioning. In this work, control over these parameters is demonstrated using a seed‐mediated synthesis that both confines ...

Investigations on the Swirl Flow Caused by an Axial Fan: A Contribution to the Revision of ISO 5801 [PDF]

open access: yes, 2012
This paper deals with the incompressible turbulent swirl flow behind an axial fan without guide vanes in a straight circular duct. The authors used High-Speed-Stereo-Particle Image Velocimetry (HSS-PIV) to visualise and quantify the flow in the duct ...

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

open access: yesAdvanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.
