Ti3C2T x ‐UHMWPE Nanocomposites—Towards an Enhanced Wear‐Resistance of Biomedical Implants

Journal of Biomedical Materials Research Part A, Volume 113, Issue 1, January 2025.
Polymeric biomedical materials, notably UHMWPE in load‐bearing joints, lack optimal mechanical and biotribological properties. This study aims to enhance Ti3C2T x ‐UHMWPE nanocomposites, improving mechanical strength, biocompatibility, and biotribological performance. Tests reveal no adverse effects on hardness, elasticity, or cytotoxicity.

Influence of Neutral and Cationic Phytoglycogen Nanoparticles on Cartilage and Ocular Lubrication

Biosurface and Biotribology, Volume 11, Issue 1, January/December 2025.
ABSTRACT Compromised hydration and biolubrication leads to untreatable disorders like osteoarthritis (OA), dry eye disease (DED) and dry mouth disease (xerostomia). Only symptomatic treatment is possible through bioactive molecules. This study aims to investigate the biolubrication properties of natural and modified phytoglycogen nanoparticles (PGNPs ...

Finger pad friction and tactile perception of laser treated, stamped and cold rolled micro-structured stainless steel sheet surfaces

Friction, 2017
Tactile perception is a complex system, which depends on frictional interactions between skin and counter-body. The contact mechanics of tactile friction is governed by many factors such as the state and properties of skin and counter-body.

Biotribology of artificial hip joints

World Journal of Orthopedics, 2015
Hip arthroplasty can be considered one of the major successes of orthopedic surgery, with more than 350000 replacements performed every year in the United States with a constantly increasing rate. The main limitations to the lifespan of these devices are due to tribological aspects, in particular the wear of mating surfaces, which implies a loss of ...

Machine learning‐based investigations of the effect of surface texture geometry on the wear behaviour of UHMWPE bearings in hip joint implants

Biosurface and Biotribology, Volume 10, Issue 4, Page 143-158, November 2024.
Abstract The purpose of this research is to develop data‐driven machine learning (ML) models capable of estimating the specific wear rate of ultra‐high molecular weight polyethylene (UHMWPE) used in hip replacement implants. The results of the data‐driven models are demonstrating a high level of consistency with the experimental findings acquired from ...

Injectable Boron Nitride‐Hyaluronic Acid Hybrid Hydrogels to Facilitate Joint Motion: Mechanical and Tribological Characterization

Advanced Therapeutics, Volume 7, Issue 10, October 2024.
The lubricating property of hexagonal boron nitride (hBN) is used for the first time to facilitate joint mobility. The effect of increasing the addition of nanoparticle (BNPs) and nanosheet (BNNSs) structures on the CoF is discussed. BNNS doped hydrogel showed an 18.9% decrease in CoF compared to untreated hydrogel.
