Journal of Biomedical Materials Research Part A, Volume 114, Issue 1, January 2026.ABSTRACT Despite the high success rates of total joint arthroplasty procedures, including total knee and hip replacements, implant failures still occur. This study investigated a potential, yet underrecognized, cause of implant failure: unintentional damage from the contact of electrosurgical blades with metal implant alloys.

TRANSITION IN THE FRETTING PHENOMENON BASED ON THE VARIABILE COEFFICIENT OF FRICTION [PDF]
Fiabilitate şi Durabilitate, 2010 Fretting is now fully identified as a small amplitude oscilatory motion which induces a harmonic tangential force between two surfaces in contact. It is related to three main loadings, i.e. fretting-wear, fretting-fatigue and fretting corrosion.Fretting

Simulation of Fretting Fatigue in Conformal and Concentrated Contacts
Tribology Online, 2011 Fretting fatigue is a possible failure mode of rolling bearings, as well as for other machine elements with contacts. For a rotating bearing it normally can occur in the interfaces between outer ring/housing, and inner ring/shaft.

ChemPhotoChem, Volume 9, Issue 12, December 13, 2025.Tetra‐ortho‐fluoroazobenzene hybrids bound to carbon nanodots (CNDs) are prepared by covalent amide coupling. These show reversible switching between trans and cis using visible light (448 nm/530 nm), while retaining emission. The hybrids are nontoxic to cells and enable optical stimulation and offering potential for advanced light‐controlled ...

Identification of contact regimes in mechanical components for the evaluation of fretting damage [PDF]
, 2013 In this work the regimes of contact in misaligned crowned splined couplings have been analyzed. Experimental tests have been performed in order to identify if fretting damage on the components appears as fretting wear or fretting fatigue.

Designing Physical Unclonable Functions From Optically Active Materials
Advanced Materials, Volume 37, Issue 49, December 10, 2025.Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Advanced Materials, Volume 37, Issue 50, December 17, 2025.A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...
