The single electromagnetic (EM) wave loss mechanism leads to suboptimal microwave absorption in dielectric materials, whereas, introducing different materials and constructing distinctive microstructures can significantly improve microwave absorption. In this study, TiB and TiB@BN powders were synthesized using boron thermal reduction and chemical solution methods. Their microwave absorption and thermal properties were systematically analyzed.

Bioelectrodes function as a critical interface for signal transduction between living organisms and electronics. Conducting polymers (CPs), particularly poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), are among the most promising materials for bioelectrodes, due to their electrical performance, high compactness, and ease of processing, but often suffer from degradation or de-doping even in some common environments (e.g.

Carbon-based microwave absorption materials have garnered widespread attention as lightweight and efficient wave absorbers, emerging as a prominent focus in the field of functional materials research. In this work, FeNi nanoparticles, synthesized in situ within graphite interlayers, were employed as catalysts to grow carbon nanofibers in situ via intercalation chemical vapor deposition (CVD). We discovered that amorphous carbon nanofibers (CNFs) can exfoliate and separate highly conductive graphite nanosheets (GNS) from the interlayers.

Solid oxide cell technologies play a crucial role in climate change mitigation by enabling the reversible storage of renewable energy. Understanding the electrochemical high-temperature reaction mechanisms and the catalytic role of the electrode and electrolyte materials is essential for advancing power-to-H technologies. Despite its significance, limited spectroscopic research focusing on nickel and yttria-stabilized zirconia (Ni/YSZ) is available.

In this paper, the authors describe an experimental study carried out on biological samples consisting of a 96-h mature Methicillin-Resistant-Staphylococcus-Aureus biofilm. The initial objective was to electrically characterize the biofilm using impedance spectroscopy, by scanning a wide range of frequencies [1 Hz ÷ 10 MHz]. Concurrently, confocal microscopy observations, XTT assays, crystal violet staining method and colony-forming unit assay were performed to characterize the biological activity.
