A Perioperative Paradigm of Cranioplasty With Polyetheretherketone: Comprehensive Management for Preventing Postoperative Complications

Frontiers in Surgery, 2022
IntroductionAt present, lots of studies have discussed the effects and outcomes of cranioplasty using polyetheretherketone (PEEK). However, interventions or management for PEEK cranioplasty got less attention.

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

Carbon Energy, EarlyView.
All‐solid‐state lithium batteries (ASSLBs) with conventional catholyte‐based composite cathodes have a theoretical energy density limit of approximately 400 Wh kg–1 and 900 Wh L–1. The design of catholyte‐free composite cathodes can break this barrier and improve the theoretical energy density up to 500 Wh kg–1 and 1000 Wh L–1. ABSTRACT The gravimetric

Fracture resistance of abutment screws made of titanium, polyetheretherketone, and carbon fiber-reinforced polyetheretherketone [PDF]

Brazilian Oral Research, 2014
Fractured abutment screws may be replaced; however, sometimes, the screw cannot be removed and the entire implant must be surgically removed and replaced. The aim of this study was to compare the fracture resistance of abutment retention screws made of titanium, polyetheretherketone (PEEK) and 30% carbon fiber-reinforced PEEK, using an external ...

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

Polyetheretherketone (PEEK) in Dentistry

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2019
There has been a constant research in identifying ideal restorative materials to replace lost dentofacial structures. Material such as wood, shell, ivory, rubbers to metals and plastics have been tried in the past. Advancements in dental materials have given dentistry more promising materials, yet each material remains short of being the ideal one ...
