An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

Advanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Circadian‐Inspired Hydrogel Moisture Electricity Generation

Advanced Science, EarlyView.
A circadian‐inspired hydrogel moisture‐electric generator enables sustainable electricity generation by autonomously current direction switching between daytime and nighttime. This reversible output is accompanied by inversion of the internal water gradient, which effectively reduce hydrogel fatigue and offers a new strategy for harvesting diurnal ...

A Scalable Double‐Sided Wet Etching Strategy for Large‐Area Mushroom‐Shaped Bionic Adhesives

Advanced Science, EarlyView.
This work presents a scalable manufacturing strategy for high‐performance, large‐area, mushroom‐shaped bio‐inspired adhesives. Using a double‐sided wet etching process, the complex 3D metal molds are fabricated rapidly and controllably. The resulting adhesive structures exhibit strong, stable adhesion under various conditions, including atmosphere and ...

Water‐Soluble Luminescent Trityl Radical for Fluorescence/Magnetic Resonance Dual‐Modal Imaging Probe

Advanced Science, EarlyView.
Stable water‐soluble luminescent tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals, TTM‐trisTP3B and TTM‐trisTP9B, were designed and successfully synthesized. They exhibited deep‐red emissions and high photostability in water. TTM‐trisTP3B exhibited dual functionality as a fluorescence imaging (FI) probe and a magnetic resonance imaging (MRI) contrast ...

Experimental Evaluation of Properties of Cross-Linked Polyethylene

Materials and Manufacturing Processes, 2003
This article describes several aspects of the production of cross-linked polyethylene. Advantages and disadvantages of chemical, or electron beam irradiation, cross-linking processes are discussed. The material under test is thermoshrinking low density polyethylene, produced at the Megarad s.r.l. (Cassino, Italy) firm.

Review on Recycling of Cross-Linked Polyethylene

Industrial & Engineering Chemistry Research
Cross-linked polyethylene is one of the most widely used thermosetting plastics. Due to its low cost, lightweight, and exceptional insulation properties against electricity and heat, it is frequently used as an insulation material for wires and cables.

Wear of Moderately Cross-Linked Polyethylene in Fixed-Bearing Total Knee Replacements [PDF]

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2012
Cross-linked polyethylene has been introduced into total joint replacement to improve wear resistance. Although the performance of highly cross-linked polyethylene is well documented clinically and experimentally for total hip replacements, the reduction

Highly Cross-Linked Polyethylene Bearing

2021
Total hip arthroplasty (THA) is the most useful treatment in symptomatic patients with late-stage osteonecrosis of the femoral head (ONFH). Unique features of ONFH such as altered bone remodeling and high prevalence of younger patients may compromise the outcome after THA.

Gel content determination in cross-linked polyethylene

Biomaterials, 1989
Gel content is the dominating parameter which affects properties and prescribes the behaviour of a given type of cross-linked polyethylene. Researchers have determined the gel content by several methods based on solvent extraction, a process which dissolves the linear thermoplastic polymer but swells only the cross-linked fraction.
