Summary: This study presents evidence of phase slippage in boron-doped nanocrystalline diamond microbridges through electrical transport measurements, despite their three-dimensional macroscopic geometry. The behavior is attributed to the unusual microstructure of the material, which forms an intrinsic Josephson junction array supporting phase slippage across the microbridge. Experimental results demonstrate the ability to deterministically switch between different superconducting states by applying electromagnetic noise pulses, indicating a metastable voltage state in these bridges.

Summary: This brief review focuses on the recent progress in studies of the heterogeneous electrochemical behavior of various boron-doped materials, extending from zero-dimensional particles to three-dimensional surfaces. Boron-doped diamond exhibits large heterogeneities induced by factors like multifaceted crystallinity, uneven boron concentration, carbon ratio, surface terminations, and grain size distribution. Nanostructured diamond surfaces allow for high areas and large aspect ratios, showing highly heterogeneous charge-transfer performance for various applications.

Summary: This study presents a coplanar waveguide resonator (CPR) for measuring kinetic inductance (L-k) and penetration depth (lambda(L)) of superconducting boron doped nanocrystalline diamond (B-NCD) at microwave frequencies. The results show that thin granular B-NCD films on Si have a large penetration depth and high kinetic inductance. These values are much larger than those typically obtained for films on single crystal diamond. The calculated surface resistance in the 0.4-1.2 GHz range at temperatures below 2 K demonstrates the potential of granular B-NCD for high quality factor superconducting microwave resonators and highly sensitive kinetic inductance detectors.

Summary: This study analyzed the electrochemical CO2 reduction using sub-microcrystalline BDD electrodes with different boron doping concentrations. Results showed that synthetic SMC BDD films with high sp2-bonded carbon do not exhibit a boron-concentration dependence in terms of CO2 reduction activity, with all electrodes achieving efficient CO2 reduction at high Faradaic efficiencies for formic acid formation. It was suggested that the presence of sp2-bonded carbon is crucial for CO2 reduction.

Summary: The study focuses on the mechanisms of dislocation formation in diamond layers doped with boron and provides rules to prevent their occurrence. It is found that incorporating boron and other dopants into the diamond lattice may lead to dislocation formation. The growth condition windows for defect-free heavily doped diamond have been deduced, based on the understanding of different dislocation generation mechanisms.

Summary: This paper introduces a device-based concept and wafer-scale fabrication process for high density electrocorticography (ECoG)-based microelectrode arrays (MEAs) using flexible and biocompatible polyimide. The MEAs are surface-mounted on printed circuit boards (PCBs) via a slot-type connector to simplify the signal recording process. In vivo tests showed good signal recording performance, and the robustness of the MEAs was verified through impedance characterization.

Summary: This study found that the boron doped diamond electrode showed the best performance in the electrochemical degradation of guaifenesin and removal of total organic carbon among 11 BDD electrodes prepared. The performance of the electrodes was influenced by the diamond crystallite structure, graphite-sp(2) C, and grain size. Solution pH affected the indirect oxidation of guaifenesin during electrolysis.

Summary: Diamond and diamond-like carbon coatings are widely used in various fields, and the hydrophilicity of these surfaces is crucial for their biocompatibility and tribological performance in aqueous environments. Different dopants such as B, N, and O have been studied for their effects on carbon film hydrophilicity, with results showing enhancement of hydrophilicity through different mechanisms, notably through spontaneous chemisorption and increased interaction in H-bond networks by B dopants.

Summary: The developments in cutting tools in the context of the fourth industrial revolution are increasingly focused on a holistic control of manufacturing processes. Diamond, especially boron-doped diamond coatings, are being used for their extreme hardness and thermal conductivity, as well as their auspicious sensing properties. Monitoring cutting temperature in real time is a challenge, but can be achieved through innovative solutions like the one-step approach of using thin diamond thermistors.
