ANTISEIZURE CHARACTERISTICS OF LEADED ALUMINUM ALLOYS UNDER DRY SLIDING CONDITIONS

Journal of Engineering, 2008
Aluminum-Silicon alloys, with soft lubricant metal, are considered to be one of the important tribological alloys which resist seizure. The effect of different lead percentages (1-20%Pb) that added to the modified eutectic Al-12%Si alloy on the wear ...

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

REINFORCING THE MATERIALS OF DENTURE BASE BY CARBON FIBERS [PDF]

Journal of the Egyptian Society of Tribology
The present study aims to develop the denture base made of PMMA by enhancing the mechanical and tribological properties. The attrition of the denture base with food and teeth generates electrostatic charge (ESC) that hurts the health of human beings ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Predicting wear of UHMWPE: decreasing wear rate following a change in direction [PDF]

, 2011
Computational tools are emerging as design tools for the development of total joint replacement with improved wear performance. The current wear models of polyethylene assume that wear is linearly proportional to sliding distance; however, it is ...

The correlation between friction coefficient and areal topography parameters for AISI 304 steel sliding against AISI 52100 steel

Friction, 2020
Dry wear experiments provide an insight detail on how severely contacting surfaces change under unlubricated sliding condition. The theory of dry sliding wear is used for understanding mixed-lubrication regime in which asperity interactions play a ...

High‐Entropy Ceramic‐Enhanced Deformable Triboelectric Nanogenerator for Noncontact Biomechanical and Raindrop Energy Harvesting

Advanced Materials, EarlyView.
A large‐area, deformable high‐entropy‐ceramic (HEC)‐doped triboelectric nanogenerator with a trilayer architecture is developed, consisting of an HEC‐doped triboelectric layer, a graphite‐like textile charge‐storage layer, and stretchable carbon black electrodes.

INFLUENCE OF FILLING MATERIALS OF DENTURE BASE BY SILVER NANOPARTICLES ON THEIR TRIBOLOGICAL PROPERTIES [PDF]

Journal of the Egyptian Society of Tribology
The aim of the present work is to reduce the voltage generated from the sliding of the denture base made of PMMA. Because PMMA is actively electrostatically charged during attrition with food and teeth, the generated voltage can harmfully influence the ...

Autonomous Folding of Soft Matter From Living Polymers

Advanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...
