Characterization of Enhanced UHMWPE‐Hap Composites Manufactured by Hot Pressing

open access: yesPolymer Composites, EarlyView.
Illustration of the production and examination of prepared composite samples. ABSTRACT In the present study, a hip joint cup/liner material has been developed using ultra high molecular weight polyethylene (UHMWPE) matrix material which is reinforced by hydroxyapatite (HAp) particles with the 0.5, 1, 2, and 4 wt.% using mechanical activation followed ...

Distribution of aortic mechanical prosthetic valve closure sound model parameters on the surface of chest [PDF]

open access: yes, 1995
Cataloged from PDF version of article.It has been previously proposed that heart valve closure sounds can be modeled by a sum of decaying sinusoids, based on the hypothesis that the heart cavity, heart walls, major vessels, and other structures in the

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Micro‐ and nanomotors in biomedical applications

open access: yesResponsive Materials, EarlyView.
Micro‐ and nanomotors (MNMs), as autonomous devices converting chemical or external energy into mechanical propulsion, have emerged as transformative drug delivery platforms in biomedicine. This review systematically outlines the design principles governing MNMs' propulsion and operation, highlights the applications of MNMs in disease treatment, and ...
