Summary: Permeability is an important factor to consider in the design of porous scaffolds for cell migration and bone tissue regeneration. This study developed a porous scaffold based on the morphological indices of cancellous bone and analyzed fluid flow through the scaffold using computational fluid dynamics. The permeability of the scaffold was compared to that of natural cancellous bone and different scaffold types. The results showed that the Negative Schwarz Primitive (NSP) scaffold had similar permeability to natural cancellous bone and could be manipulated by changing the curvature to support cell migration and tissue regeneration.

Summary: This study investigates the effect of compressive mechanical boundary conditions and the addition of beta-tricalcium phosphate (beta TCP) on the development of zonal ligament-to-bone entheses. The results show that compressive boundary clamps and beta TCP can guide ligament fibroblasts to produce zonal gradients in collagen organization, mineralization, and matrix composition, closely resembling immature ligament-to-bone attachments. This culture system provides a promising platform for understanding and promoting enthesis regeneration in graft repair and engineered replacements.

Summary: This article introduces a new polymer material, PAEK-COOH, which is synthesized and fabricated into hierarchically controllable porous scaffolds via low-temperature 3D printing. The prepared scaffolds exhibit comparable mechanical strength to trabecular bone and the nanoporous surface promotes cellular adhesion and hydroxyapatite mineralization through electrostatic interaction. In vivo experiments demonstrate the superior osseointegration of the PAEK-COOH scaffolds compared to PEEK, without the need for additional active ingredients.

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.
