Summary: Magnesium phosphate cement (MPC) has been modified to be porous by using calcium carbonate and citric acid as foaming agents. The resulting MPC with 3% CaCO3/CA showed improved physicochemical properties and enhanced biocompatibility. In animal experiments, 3%CaCO3/CA-MPC exhibited better bone regeneration compared to the blank group, and slightly lower regeneration compared to the Bio-Oss(R) group. This study suggests that porous MPC foamed with calcium carbonate and CA is a promising material for bone regeneration.

Summary: Composite biomaterials consisting of PVP nanofibers containing MBG 80S15 nanoparticles were produced by electrospinning. The mechanical properties of the nanofibrous mats depended on the thermal crosslinking parameters and the presence of MBG particles. Degradation tests showed that the presence of MBG accelerated the degradation of the mats. In vitro bioactivity evaluation confirmed that the bioactive properties of MBG were maintained when incorporated into PVP nanofibers. The materials showed no cytotoxic effects and demonstrated potential for use in bone tissue engineering.

Summary: In this study, Fe-doped MFe-LDHs (M = Co, Ni, Cu, Mn) were synthesized to investigate the influence of Fe on their electrocatalytic activity for the oxygen evolution reaction (OER). It was found that the Fe content had a significant impact on the catalytic performance, with an optimal Fe content resulting in the highest OER activity. Excess Fe, however, compromised the activity. Additionally, a volcano relationship was observed between the intermediate adsorption and Fe content, and intermediate adsorption capacitance was identified as a new activity descriptor for electrocatalysts.

Summary: Topological materials with surface metallic states and high carrier mobility have been considered as ideal catalysts for heterogeneous reactions. The relationship between their catalytic performance and topological states is still under debate. Through studies on the hydrogen evolution process under different doping and strain conditions, it has been demonstrated that the excellent catalytic performance indeed originates from the topological properties. A linear relationship between the length of Fermi arcs and Gibbs free energy (Delta G(H*)) has been found, providing direct evidence linking enhanced catalytic performance and surface Fermi arc states, and clarifying the fundamental mechanism in topological catalysis.

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: Our study reveals that physics-informed neural networks (PINN) are often local approximators after training. This led to the development of a novel physics-informed radial basis network (PIRBN), which maintains the local approximating property throughout the training process. Unlike deep neural networks, PIRBN consists of only one hidden layer and a radial basis activation function. Under appropriate conditions, we demonstrated that PIRBNs can converge to Gaussian processes using gradient descent methods. Furthermore, we investigated the training dynamics of PIRBN using the neural tangent kernel (NTK) theory and explored various initialization strategies. Numerical examples showed that PIRBN is more effective than PINN in solving nonlinear partial differential equations with high-frequency features and ill-posed computational domains. Moreover, existing PINN numerical techniques such as adaptive learning, decomposition, and different loss functions can be applied to PIRBN. The reproducible code for all numerical results is available at https://github.com/JinshuaiBai/PIRBN.
