Summary: Due to the serious electromagnetic pollution caused by the widespread use of radio frequency equipment, the study of electromagnetic interference (EMI) shielding materials has been a long-standing topic. Carbon fiber and graphene composites have great potential as EMI shielding materials due to their unique microstructure and electrical conductivity. In this work, a novel kind of core-shell composite is fabricated based on the pore-rich pine needles-derived carbon fibers (PNCFs) core and the graphene shell. The composite exhibits excellent EMI shielding effectiveness (SE > 70 dB over X-band (8.2-12.4 GHz)) and achieves a maximum value of similar to 77 dB at 10.4 GHz, which is higher than many biobased EMI shielding materials in the recent literature.

Summary: By employing a coaxial wet-spinning assembly strategy, multifunctional hollow core-shell fibers with a ductile polyvinylidene fluoride (PVDF) shell and compactly ordered MXene hollow core were fabricated to achieve satisfactory chemical resistances, high electrical conductivity, and enhanced ductility. The partial hydroxylation of PVDF during coagulation enhanced the interfacial interaction between the PVDF and MXene layers. The hollow core, consisting of a compact and ordered MXene layer, provided the fibers with high electrical conductivity, while the PVDF shell endowed them with enhanced ductility and excellent resistances to acid, alkali, and seawater. The hollow core-shell structure made the fibers lightweight and facilitated multiple scattering of electromagnetic waves, resulting in increased electromagnetic wave absorption and attenuation. The resulting fibers exhibited exceptional Joule heating performances and a high electromagnetic interference shielding effectiveness, making them promising for wearable heating and electromagnetic interference shielding applications.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
