High Modulus, Strut-like poly(ether ether ketone) Aerogels Produced from a Benign Solvent
GelsPoly(ether ether ketone) (PEEK) was found to form gels in the benign solvent 1,3-diphenylacetone (DPA). Gelation of PEEK in DPA was found to form an interconnected, strut-like morphology composed of polymer axialites.

Carbon-fiber-reinforced polyetheretherketone instrumentation in metastatic spine tumor surgery: technical considerations and potential pitfalls to avoid [PDF]
Asian Spine JournalCarbon-fiber-reinforced polyetheretherketone (CFR-PEEK) instrumentation has been reported in recent years for metastatic spine tumor surgery (MSTS). The benefits of CFR-PEEK include imaging artifact reduction, which enables more efficient follow-up and ...

Advanced Materials, EarlyView.This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

Inflammatory response to implantation of transparent nanocrystalline yttria-stabilized zirconia using a dorsal window chamber model. [PDF]
, 2016 The long-range goal of the windows to the brain (WttB) is to improve patient care by providing a technique for delivery and/or collection of light into/from the brain, on demand, over large areas, and on a chronically-recurring basis without the need for

Advanced Materials, EarlyView.Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Evaluating the bioactivity of a hydroxyapatite-incorporated polyetheretherketone biocomposite
Journal of Orthopaedic Surgery and Research, 2019 Background Polyetheretherketone (PEEK) exhibits stable chemical properties, excellent biocompatibility, and rational mechanical properties that are similar to those of human cortical bone, but the lack of bioactivity impedes its clinical application ...

Advanced Materials, EarlyView.This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...
