High‐Performance X‐Band Electromagnetic Interference Shielding in Flexible Barium Hexaferrite/Cobalt‐Based Microwires/Silicone Rubber Ternary Composites via Magnetic–Conductive Synergy

Advanced Electronic Materials, EarlyView.
A flexible ternary composite combining barium hexaferrite (BHF), Co–Microwires, and silicone rubber exploits magnetic–conductive synergy to deliver tunable X‐band EMI shielding, reaching a 16.9 dB at 9.8 GHz (surpassing the 10 dB industrial benchmark). Shielding behavior shifts between reflection and absorption with BHF loading and Co–Microwires counts

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.
