Mechanism of thermal decomposition of poly(ether ether ketone) (PEEK) from a review of decomposition studies [PDF]

open access: yesPolymer Degradation and Stability, 2010
A review of the literature on the flammability and decomposition of poly(oxy-1,4-phenyleneoxy-1,4-phenylenecarbonyl-1,4-phenylene) (PEEK) is presented. This paper provides an overview of the flammability of PEEK and its decomposition mechanisms. Based on

In vitro evaluation of delamination resistance of PEEK and CFR-PEEK

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2021
Poly-ether-ether-ketone (PEEK) and carbon fiber reinforced PEEK as orthopedic implant materials exhibit excellent material properties. Although delamination of PEEK materials has been reported in knee joint wear research, the delamination resistance behavior remains unclear. In this study, the delamination resistance of PEEK materials was investigated;

A Peek into PEEK: the trending dental biomaterial - A Review

Journal of Pharmaceutical Negative Results, 2022
Introduction: Thermoplastic polymers have many potential uses in medicine and dentistry as an alternative to the commonly used titanium. Due to several advantages of these materials, metal-free restorations are performing an important role in current medical therapies. The aim of this review was to evaluate Polyetheretherketone (PEEK) as an alternative

Peek

Proceedings of the 2013 conference on Computer supported cooperative work companion, 2013
Ever wondered if it was a good time to call your spouse, child, or friend? Do you sometimes just want to know if they are on their way to meet you? With Peek you can request the activity state (e.g. walking, in-vehicle, at-rest) and location of a phone when needed.

A game of hide and peek

Developmental Cell, 2021
A continuous cuticle is required for normal development of Arabidopsis embryos. Despite this barrier, embryos remain sensitive to outside signals. In this issue of Developmental Cell, De Giorgi et al. show that the embryonic cuticle is relatively permeable and becomes sealed during germination in response to peptide signaling.

Peek-a-drawer

CHI '02 extended abstracts on Human factors in computer systems - CHI '02, 2002
Peek-A-Drawer is a new communication device that uses furniture to support lightweight communication between people. It provides virtual shared drawers that connect family members who are located at a distance. When a user puts something in the upper drawer and closes it, a photograph is taken automatically and the image appears in the lower drawer at ...

Computer-Designed PEEK Implants

Journal of Craniofacial Surgery, 2014
Polyetheretherketone (PEEK) is a synthetic material that was used initially in spine and hip surgery. It has the properties of being biocompatible, resistant to thermal and ionizing radiation, and resembles cortical bone biomechanically. These favorable characteristics have led to the increasing use of PEEK implants for calvarial defects which remain a

The PEEK measurement program

ACM SIGMETRICS Performance Evaluation Review, 1984
A computer program called PEEK has been written to measure PL/I computer programs. The PEEK system makes three types of measurements of PL/I programs. PEEK measures (1) basic statistics, (2) cyclomatic complexity, and (3) software science metrics. Each of these types of measures gives a different insight into the nature of the particular computer ...

Wear and rolling contact fatigue of PEEK and PEEK composites

Tribology International, 2013
Abstract Wear and rolling contact fatigue were investigated on unfilled PEEK and on three PEEK short fiber reinforced composites. For this aim, roller-shaped specimens were subjected to rolling contact tests at different contact pressure levels. Wear rate- pv product and contact pressure-life diagrams were obtained, depending on material hardness ...

A Peek at the Future Internet

2011
The Internet "connectivity machine" is the generative engine of our modern digital society. It has been the launching pad of the Web (now the Web 2.0), truly the largest and most versatile information system ever built. While the Web phenomenon relentlessly continues, scientists worldwide are now living the dream of yet a more generative next ...
