Multiple‐Repeated Plasma Surface Treatments for Significantly Improving Bonding Performance of Metal‐Carbon‐Fiber‐Reinforced Thermoplastic Polymer Dissimilar Adhesive Joints

open access: yesAdvanced Engineering Materials, EarlyView.
Multiple plasma surface treatments improved the Mode I fracture energy of metal‐carbon‐fiber‐reinforced thermoplastic polymer (CFRTP) joints by ≈240% compared to single treatments and nearly 2000% over untreated joints. This significant enhancement, achieved without modifying CFRTP surface roughness, is attributed to improved chemical bonding at the ...

EFFECT OF METHOTREXATE ON FRACTURE HEALING

open access: yesFUKUSHIMA JOURNAL OF MEDICAL SCIENCE, 2011
Low doses of methotrexate (MTX) are safe and effective for treating adult and juvenile rheumatoid arthritis. However, because this powerful anti-inflammatory drug might negatively influence the healing of wounds and fractures, MTX administration is often stopped during surgical procedures.

Design and Evaluation of 3D‐Printed Polylactic Acid Composites Reinforced with Biodegradable Bamboo Powder and Jute Powder

open access: yesAdvanced Engineering Materials, EarlyView.
The study investigates 3D‐printed polylactic acid (PLA) composites with biodegradable bamboo and jute powder fillers. Mechanical, thermal, structural properties, and rheological behavior are discussed to evaluate composite performance. Morphological characterization indicates uniform dispersion and adhesion of the fillers in the PLA matrix with the ...

A geometrically inspired constitutive framework for damage and intrinsic self-healing of elastomers [PDF]

open access: yesarXiv
Autonomic interfacial self-healing in elastomers enables their reprocessing and recycling, making them valuable for applications such as ballistic resistance, surface coatings, adhesives, and biomedical materials. This article prescribes a geometry-based damage-healing theory for autonomic healing in elastomers, built on a framework where damage ...

ASSESSMENT OF SERUM PARATHYROID HORMONE FLUCTUATION DURING FRACTURE HEALING WITH ORAL ADMINISTRATION OF DRUG CISSUS QUADRANGULARIS IN PATIENTS OF BONE FRACTURE [PDF]

open access: yes, 2017
This study gives an understanding about the PTH mode of action as it accelerates the natural fracture healing process by shrinking callus size and increasing degree of mineralization of the fracture callus; thereby restoring intrinsic material properties.

Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

An evaluation of the conservative management of fractures with plaster in a Maltese primary health centre [PDF]

open access: yes, 2018
Introduction: Fracture management still remains a grey area in primary care internationally. In Malta, conservative fracture management operates as the Plaster Slab Service, a service which has never been evaluated. The purpose of this study is to assess

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

M2 macrophages are closely associated with accelerated clavicle fracture healing in patients with traumatic brain injury: a retrospective cohort study

open access: yesJournal of Orthopaedic Surgery and Research, 2018
Background Mounting evidence indicate patients with traumatic brain injury (TBI) have an accelerated fracture healing. The healing process of bone fractures is greatly dependent on infiltrated macrophages.
