Summary: In this study, hydroxyapatite microparticles from animal bones were synthesized and reinforced with beneficiated kaolin for the first time using the sol-gel route to improve the mechano-biological properties of the bioceramic materials. Sintering at different temperatures resulted in the formation of dominant hydroxyapatite phase, with the reinforced samples showing improved compressive strengths. In-vitro experiments confirmed the degradability and compatibility of the scaffolds, with sample K-HAp 900 also exhibiting inhibitory potentials for bacterial strain E. Coli.

Summary: In this study, a three-dimensional printed porous multilayer scaffold made of cold-water fish skin gelatin was developed for osteoarticular cartilage regeneration. The scaffold mimics the structure of native cartilage, allowing chondrocytes to adhere, proliferate, and communicate, as well as transport nutrients and prevent further joint damage. Moreover, the gelatin scaffolds were found to be nonimmunogenic, nontoxic, and biodegradable. Implanting the scaffold into rat cartilage defects resulted in satisfactory repair outcomes in an animal model. Therefore, cold-water fish skin gelatin scaffolds have promising applications in regenerative medicine.

Summary: A hybrid numerical model based on the lattice Boltzmann method and finite difference method is developed to investigate the control of viscous fingering using electrohydrodynamics. The effects of electric field strength and direction, as well as fluid properties, on viscous fingering are studied extensively. It is found that a horizontal electric field can either promote or suppress viscous fingering, depending on the permittivity ratio and conductivity ratio. A phase diagram is established to characterize the interfacial morphologies under different electric field orientations and fluid properties.

Summary: In this study, a deep learning model is proposed to accurately and robustly detect early clinical keratoconus (KCN). By extracting features from three different corneal maps using Xception and InceptionResNetV2 deep learning architectures, and then fusing the features, subclinical forms of KCN can be detected with high accuracy. The model achieved an AUC of 0.99 and an accuracy range of 97-100% in distinguishing normal eyes from eyes with subclinical and established KCN. The model was further validated on an independent dataset with an AUC of 0.91-0.92 and an accuracy range of 88-92%. This model is a step toward improving the detection of clinical and subclinical forms of KCN.

Summary: This study systematically investigated the sliding behaviors of one-dimensional carbon nanotubes in a polymer matrix through atomistic simulations. The functionalized nanotubes showed significantly enhanced interfacial shear strengths due to the strong mechanical interlocking effect. However, excess volume within the functionalized bundle structure weakened the non-bonded interaction. Covalent cross-linking allowed the simultaneous pulling out of surrounding nanotubes while extracting the central nanotube, attributed to filler-filler and filler-matrix interactions. The findings have implications for fiber design and high-performance polymer nanocomposites with one-dimensional nanomaterials.

Summary: Electroosmotic flow (EOF) is a common phenomenon in microfluidic systems. The study compared the electrochemistry (EC) model, which takes into account electrode reactions and water dissociation, with the traditional electrokinetic (EK) model. The EC model showed that electrode reactions significantly reduce the EOF velocity and cause changes in pH and ion concentration within the microchannel. The results provide valuable insights for manipulating fluid flow and molecular transport in microfluidic systems.

Summary: Controlling magnetism via electric fields instead of magnetic fields has long been envisioned as a revolutionary technology, but it faces challenges of volatility, high energy cost, and low storage density. In this work, effective approaches to achieve magnetic control in bilayer NiI2 are developed through electrostatic doping and polarization field. The interlayer antiferromagnetic to ferromagnetic transition has been observed when the critical electron doping concentration reaches 0.625%. The critical concentration of magnetic transition can be reduced or increased depending on the polarization direction on the ferroelectric substrate of Sc2CO2.
