Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Effects of Hydrothermal-Chemical Treatments on Bending Performance and Physical-Mechanical Properties of Four Timber Species

BioResources
The bending behavior of four key timber species (Fraxinus chinensis, teak, rubberwood, and Pinus yunnanensis) was evaluated under hydrothermal-chemical treatments. Controlled experiments at varying moisture contents (20 to 60%), temperatures (100 to 140 °

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

Advanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Enhancing the Flexural Characteristics of Stabilized Kaolinite Clay by Reinforcing with Composite Fiber [PDF]

پژوهش‌های زیرساخت‌های عمرانی
In this research, a new type of fiber known as composite fibers has been utilized to enhance the flexural properties of stabilized clay. The core of the composite fiber consists of elastane, while its shell is composed of numerous polyester fibers.

Three-point bending of electrospun TiO2 nanofibers

, 2005
TiO2 (anatase) and TiO2/PVP nanocomposite nanofibers with average diameters of 53 and 109 nm, respectively, were synthesized via sol-gel chemistry in combination with an electrospinning process. This produced continuous nanotibers that were characterized

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Comparison between three-point and four-point flexural tests to determine wood strength of eucalyptus specimens

Maderas: Ciencia y Tecnología, 2018
Comparison between flexural wood strength values obtained from three-point and four-point bending tests in wood were only reported in few previous works, but remains unclear.
