Graphene–Catechol Dental Sealant: Antibacterial and Mechanical Evaluation

Advanced Engineering Materials, EarlyView.
This study presents dental sealants made with graphene and L‐DOPA‐modified graphene. L‐DOPA enhances graphene dispersion, improving sealant properties. The material shows antibacterial activity against S. mutans and L. casei, along with high strength and elasticity.

Flow-Performance Relationship and Tournament Behavior in the Mutual Fund Industry [PDF]

, 2008
In this paper, we interpret the flow-performance relationship as an incentive scheme implicitly given to mutual fund managers by mutual fund investors. We show that the flow-performance relationship varies not only with economic activity but also across ...

Titanium‐S23: A New Alloy with Ultra‐High Tensile Toughness Directly from the Solid‐State Processing of Recycled Ti–6Al–4V and Ti–5Al–5Mo–5V–3Cr Powders using Field Assisted Sintering Technology

Advanced Engineering Materials, EarlyView.
This study explores combining two existing aerospace titanium alloy powders, processing them via field‐assisted sintering technology and the subsequent discovery of a novel alloy composition, termed S23, with ultra‐high tensile toughness. Fine‐scale alpha precipitates favorably form in the alloy despite the relatively slow cooling, providing an ...

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

Advanced Engineering Materials, EarlyView.
In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Single‐Crystal Castability of CM186LC Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The optimal conditions to obtain single‐crystal (SX) castings of the directional solidification nickel‐based superalloy CM186LC, are investigated. Cylindrical samples are cast via a proprietary SX Bridgman process. The effect of solidification rates (V) ranging from 1 to 10 mm⋅min−1 on the microstructure is explored.
