Influence of Hornification Treatment and Fiber Length on the Performance of Recycled Polypropylene Composites

open access: yesPolymer Composites, Volume 47, Issue 5, Page 4793-4803, 10 March 2026.
Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,

Bioresorbable Plates and Screws for Clinical Applications: A Review

open access: yesJournal of Healthcare Engineering, Volume 3, Issue 2, Page 243-260, 2012., 2012
Bioresorbable implants are being widely used for fracture fixation in orthopaedic surgery and the market is expanding rapidly worldwide. Bioresorbable materials slowly dissolve in the human body, such that a second operation to remove the synthetic material is not needed. Bioresorbable implants have expanded the armamentarium of the surgeon, especially

Prognostic Impact of Spontaneous Conversion to Sinus Rhythm in Patients With Symptomatic Paroxysmal Atrial Fibrillation: A Propensity‐Matched Follow‐Up Study

open access: yesJournal of Cardiovascular Electrophysiology, Volume 36, Issue 12, Page 3222-3230, December 2025.
ABSTRACT Background Paroxysmal atrial fibrillation (PAF) patients do not invariably progress to persistent AF, with a consistent group of patients showing AF regression during follow‐up. The prognostic implications of spontaneous conversion (SCV) to sinus rhythm (SR) in those patients has never been evaluated yet.

Nanocrystalline Diamond as a Coating for Joint Implants: Cytotoxicity and Biocompatibility Assessment

open access: yesJournal of Nanomaterials, Volume 2008, Issue 1, 2008., 2008
Nanocrystalline diamond (NCD) coatings combine a very low surface roughness with the outstanding diamond properties, such as superlative hardness, low self‐friction coefficient, high wear and corrosion resistance, and biotolerance, which are ideal features for applications in medicine (knee and hip replacement) and surgical tools.

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

open access: yesAdvanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

Influence of Phase Composition on Sintered Microstructure of Combustion Synthesized Oxides

open access: yesAdvances in Materials Science and Engineering, Volume 2007, Issue 1, 2007., 2007
The effects of powders synthesis methods (urea‐combustion synthesis (CS) and conventional solid‐state (SS) reaction) on the sintering ability, microstructural features, and mechanical properties of Al2O3, MgAl2O4 spinel, and 20 wt.% ZrO2–MgAl2O4 upon sintering at 1625C∘ were investigated.
