Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

open access: yesFire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Microelectromechanical system‐based devices for the diagnosis, treatment, and monitoring of ophthalmic diseases

open access: yesInterdisciplinary Medicine, EarlyView.
Due to the characteristics of miniaturization, high sensing performance, integration, and high comfort, MEMS‐based devices were employed to design sensors, imaging systems, drug delivery systems, retinal prosthesis, surgical tools, and wearable products for the ophthalmic disease diagnosis, treatment, and monitoring.

How Poly(Ethylene Terephthalate) (PET) From Mechanically and Chemically Recycling Affects the Performance of Monopolymer Blends

open access: yesPolymer Engineering &Science, EarlyView.
Mechanical recycling process and chemically recycled commercial blend pellets. ABSTRACT From 2030, in line with the new directive issued by the European Union, manufacturers of plastic beverage bottles will have to include at least 30% recycled plastic, calculated as an average for all bottles placed on the market in each Member State. In this context,

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.
