Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Efficacy of Ultrasonically Activated 12.5% Ethanolic Extract of Salvadora persica, Smear Clear, 0.2% Chitosan, 10% Citric Acid in Elimination of Intracanal Smear Layer: A Scanning Electron Microscope Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: The chemomechanical preparation technique is gaining significant importance. Sodium Hypochlorite (NaOCl) and Ethylenediaminetetraacetic acid (EDTA) are traditional irrigants used, but various studies have shown their deleterious effects on ...

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

Advanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

Advanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

Evaluation of Effect of Natural Extract Sodium Gluconate on Smear Layer and Dentine Decalcification Compared with EDTA – An In-vitro Study

European Endodontic Journal, 2023
Objective: Mechanical instrumentation of the root canal system generates a smear layer on the canal walls which are removed most commonly with the help of chelators such as ethylenediaminetetraacetic acid (EDTA) but can potentially cause severe dentinal ...

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts

Advanced Functional Materials, EarlyView.
The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.
