Summary: We report on the growth of novel microcrystalline diamond-germanium composite films on Si substrates using microwave plasma assisted chemical vapor deposition. The structure of the films strongly depends on the deposition temperature, with competing Ge grains and diamond crystallites at lower temperatures, and enhanced diamond growth at higher temperatures. The composite shows optical transmission for wavelengths above 10 mm and exhibits bright optical emission of GeV color centers at 601 nm. The effective coefficient of thermal expansion can be tuned by adjusting the Ge volume fraction, facilitating integration with semiconductor wafers.

Summary: A new prototype 3D diamond dosimeter, featuring laser-written graphitic surface connections and bonding pads, was tested on medical dosimetry. The device was made with a polycrystalline chemical vapour deposition diamond substrate and showed potential advantages over single crystal diamond in terms of size and cost. The 3D design of the device allowed for more efficient charge collection and reduced distortion of the electric field close to the surface of the diamond. By removing metal-diamond contacts, the operating voltage was lowered without affecting dose-rate independence.

Summary: Polymeric composites with high thermal conductivity are needed for solving heat accumulation issues. In this study, an interconnected three-dimensional polysulfone/hexagonal boron nitride-carbon nanofiber skeleton was prepared and embedded into epoxy. The resulting composite showed a high thermal conductivity of 2.18 W m -1 K -1 at a low filler loading, with a 990% enhancement compared to neat epoxy. The enhanced thermal conductivity was attributed to the 3D structure and synergistic effect of boron nitride and carbon nanofiber. The thermal conductivity of the composite can be further increased through post-heat treatment, resulting in potential applications in thermal management.

Summary: This study investigates the radiation tolerance and timing properties of 3D diamond detectors fabricated by laser engineering on synthetic Chemical Vapor Deposited (CVD) plates. The results demonstrate that the radiation tolerance increases significantly when moving from standard planar architecture to 3D architecture, and this increase is further enhanced with higher density of columnar electrodes. Additionally, the maximum applicable bias voltage also increases significantly after high fluence irradiation, potentially due to the passivation of defects. Experimental analysis allows for predicting device performance at higher fluence levels.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
