Crosslinked Gelatin‐Polycaprolactone Scaffolds: Balancing Biocompatibility and Inflammatory Response for Tissue Engineering Applications

Polymer Engineering &Science, EarlyView.
Crosslinked gelatin‐functionalized PCL scaffolds exhibited enhanced hydrophilicity, structural stability, and porous interactions. In vitro assays demonstrated improved osteoblast adhesion, viability, and proliferation without cytotoxicity, while in vivo evaluation showed no adverse inflammatory response, supporting their potential application in ...

Thermodynamics‐Driven Phase‐Field Kinetics Simulation for Experiment‐Validated Design of CoNi‐Based Superalloys

Rare Metals, EarlyView.
ABSTRACT Thermodynamic prediction‐driven phase‐field kinetic simulation, with experimental verification, is utilized to explore the high‐performance cobalt–nickel based (CoNi‐based) superalloys. The roles of aluminum (Al) in microstructural evolution and precipitation kinetics of ordered L12‐γ′ strengthened Co–Ni–xAl superalloys are revealed. The alloy

Microhardness of Semicrystalline Polymers [PDF]

, 1986
A new approach to justify the dependence of microhardness of semicrystal-line polymers, specially polyethylene, upon average crystal thickness is given. A basic model of deformation under local compression is proposed in terms of the heat dissipated by the plastically deformed crystals and the volume of crystals destroyed under the indenter.

In Situ Tailoring of FCC Ductile Phases for High‐Strength Wear‐Resistant Crack‐Free W‐Based Metallic Coatings

Rare Metals, EarlyView.
ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

Achieving Excellent Strength–Ductility in Nb‐Si Superalloys via Stable Bi‐Phases Structure and Nano‐Precipitation Behaviors

Rare Metals, EarlyView.
ABSTRACT Nb‐Si‐based superalloys are considered as the most potential candidate materials for nickel‐based superalloys due to the lower density and higher using temperature. Here, a type of stable Nbss/γNb5Si3 bi‐phases structure with a coherent interface has been successfully designed. Additionally, the Nbss and γNb5Si3 phases showcase the orientation
