Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

The FGF/FGFR System in the Biology and Therapeutic Landscape of Pediatric CNS Tumors

Medicinal Research Reviews, EarlyView.
ABSTRACT Central nervous system (CNS) tumors are the most common solid malignancies in children, comprising a highly heterogeneous group of neoplasms defined by distinct molecular alterations and clinical behaviors. Advances in molecular genetics have underscored the relevance of specific signaling pathways in driving pediatric tumorigenesis, among ...

An Improved Air Film Model for Studying the Tilt Characteristics of Aerostatic Thrust Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, an improved mass‐spring model that treats the lubricating air film as distributed springs is proposed to calculate the static and dynamic angular stiffness of aerostatic thrust bearings. The proposed model refines the traditional mass‐spring model by introducing the spatially varying mechanical properties of the air film and the

Myasthenia Gravis and Thymoma

Muscle &Nerve, EarlyView.
ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.

Experimental Comparative Analysis of Hole‐Making Strategies and Cutting Parameters on Flexural Properties and Induced Delamination in S2 Glass and Basalt Fiber‐Reinforced Polymers

Polymer Composites, EarlyView.
Hole‐making strategy and machining parameters influence delamination and hole quality in S2‐glass and basalt FRP composites, which subsequently affet flexural performance. Improved hole integrity leads to enhanced structural performance during three‐point bending.

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

Polymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.
