Summary: Hybrid soft magnetic composites were fabricated using bimodal amorphous Fe73Si11B11C3Cr2 and crystalline Fe50Co50 powders via MIM. The addition of Fe50Co50 powder decreased the permeability but increased the saturation induction. Composites with higher fraction of Fe50Co50 exhibited better magnetic saturation and bias performances. Core loss was mainly influenced by particle size distribution, and finer Fe50Co50 powders distributed in interstices led to lower eddy current loss and core loss.

Summary: Amorphous Fe73Si11B11C3Cr2 powders were coated with a layer of Fe3O4 through hydrothermal reactions to fabricate soft magnetic composites (SMCs). The insulating Fe3O4 layer confined the eddy current in individual amorphous particles while the magnetic diluting effect was avoided due to the ferromagnetic properties of Fe3O4. Hot pressing the coated powder at temperatures near the glass transformation temperature of the metallic glass powder resulted in SMCs with high density and good magnetic properties under a low pressure of 600 MPa. The SMCs fabricated at 430 degrees C exhibited the best magnetic properties, and further improvement was achieved through annealing at the same temperature.

Summary: Traditional bone fixation devices made from inert metal alloys provide structural strength for bone repair but are limited in their ability to actively promote bone healing. However, injection and compression molding techniques have successfully been used to manufacture composite silk-ceramic scaffolds comprising hydroxyapatite and silk fibroin, showing the potential for large-scale manufacturing of natural protein-based bone grafts and fixation devices. This work demonstrates a step closer towards moving bone tissue engineering to large-scale manufacturing of resorbable bone grafts and fixation devices based on natural proteins.

Summary: A machine learning method aided by domain knowledge is proposed to predict the saturated magnetization (Bs) and critical diameter (Dmax) of soft magnetic metallic glasses (MGs). Two datasets based on published experimental works about soft magnetic MGs were established. A general feature space was developed and proven to be adaptive for different prediction tasks in ML model training. The ML models demonstrated better predictive performance than traditional knowledge-based estimation methods. Additionally, domain knowledge aided feature design effectively reduced the number of features without significantly compromising prediction accuracy. Finally, the binary classification of Dmax of soft magnetic MGs was investigated.

Summary: This study investigates the effects of injection temperature, injection pressure, and fiber content on the mechanical properties of weld lines in carbon fiber-reinforced nylon (PA-CF) composites. The results indicate that the presence of weld lines negatively affects the mechanical properties of the composites, primarily due to poor fiber orientation in the weld line regions. Additionally, increasing injection temperature and pressure can improve the mechanical properties of composites with low fiber content, but weaken those with high fiber content.

Summary: A study was conducted on the relationship between injection molding parameters and the resulting fiber length, orientation, and mechanical properties of highly reinforced long fiber thermoplastic (LFT) polypropylene (PP). It was found that the longest fibers were obtained under the conditions of lowest backpressure and highest screw speed. The importance of backpressure increased as the amount of glass fiber reinforcement increased, contrary to less reinforced thermoplastics. Injection speed did not affect fiber breakage, but had a significant impact on fiber orientation and tensile strength, especially when the average fiber length was below 1000 μm. When the average length exceeded 1000 μm, the fibers formed a mesh that thickened the core region and hindered orientation, resulting in reduced tensile strength but improved impact resistance.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
