AFTER-TREATMENT OF POLYPROPYLENE FIBRE

Sen'i Gakkaishi, 1962
The spun yarn may be drawn several times its original iength. This drawing is the strengthforming structural change which adapts polypropylene to a wide range of utility in the textile field.The drawing ratio has a considerable influence on the mechanical properties of fibres, and the maximum ratio is desirable.

Block Copolymers: Emerging Building Blocks for Additive Manufacturing

Advanced Functional Materials, EarlyView.
This review addresses how block copolymer (BCP) physics and rheology have led to the widespread use of BCPs in advanced additive manufacturing techniques, with particular emphasis on the untapped potential of these nanostructured materials toward achieving multi‐scale architected materials with unique, programmable material properties.

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

Advanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

Characterization of Microplastics in Human Gastric Cancer and Control Tissues and Analysis of Associated Genetic Features

Advanced Healthcare Materials, EarlyView.
This study characterizes the presence of microplastics in human normal gastric, para‐tumor, and gastric tumor tissue and confirms the association between microplastic exposure and lymph node metastasis in gastric cancer. This study explores the transcriptomic changes induced by microplastic exposure, laying the foundation for further investigation into

Medical Fabrics with Non‐Antibiotic, Supramolecular Antimicrobial Coatings: A Preventive Approach to Combat Biofilm Formation and Bacterial Dissemination

Advanced Healthcare Materials, EarlyView.
The study presents an antibiotic‐free strategy using medical fabrics coated with supramolecular assemblies of polyarginine and hyaluronic acid. These coatings showed strong antimicrobial and anti‐biofilm activity in vitro and in vivo, achieving major bacterial load reductions, including against MRSA.

Behaviour of different types of fibre reinforced concrete without admixture [PDF]

, 2016
In this paper the behaviour of the normal concrete and concrete with different types of fibre (steel, macro-polypropylene and micro-polypropylene fibres) have been studied; in terms of the compressive strength, split tensile strength, density, and the ...

Injectable Stimuli‐Responsive Amphiphilic Hydrogel for Rapid Hemostasis, Robust Tissue Adhesion, and Controlled Drug Delivery in Trauma and Surgical Care

Advanced Healthcare Materials, EarlyView.
Fast‐acting hydrogel seals bleeding wounds as the illustrated injectable, pH‐responsive network rapidly gels in situ to stop hemorrhage, adhere strongly to wet tissue, and release antibiotics in a controlled, pH‐dependent manner. The material withstands high pressures, shows excellent biocompatibility, and degrades safely, offering a versatile platform
