Summary: The field of bone tissue engineering is developing various bone graft substitute materials to reconstruct new bone tissue while maintaining native bone characteristics. Insufficient scaffold degradation is currently the critical limitation for tailoring bone formation turnover rate. This study examines novel scaffold formulations, and results show that the CS/HAp/FAp 1:1 formulation can improve scaffold degradation and bone regeneration, providing a cost-effective alternative to traditional methods (BMP-2).

Summary: In this study, a core-shell poly(& epsilon;-caprolactone)/chitosan/ polyvinyl alcohol (PCL/CS/PVA) guided bone regeneration (GBR) membrane loaded with resveratrol (RSV) was fabricated. The loaded membrane exhibited superior osteogenic induction ability compared to regular GBR membranes. In vitro and in vivo experiments demonstrated that the PCL/CS/PVA GBR membrane loaded with 0.5% RSV could efficiently release RSV, induce osteogenic differentiation, and promote bone regeneration.

Summary: The study reports Dirac nodal line crossings in PtPb4, which arise from the nonsymmorphic symmetry of its crystal structure. The results show that the nodal lines remain gapless in the absence of spin-orbit coupling (SOC), but the SOC lifts the band degeneracy everywhere except at a set of isolated points. However, the observed nodal line has a smaller bandwidth than predicted by density functional theory (DFT).

Summary: The Kagome lattice plays an important role in condensed matter physics for studying the interaction between electron correlation, topology, and frustrated magnetism. Recent research on Kagome metals has revealed various correlation-driven distortions, including charge density waves and superconductivity. The study of a new Kagome metal, Yb0.5Co3Ge3, shows similar behavior to AV(3)Sb(5) compounds, indicating a temperature-dependent kink in resistivity and structural distortion. The findings raise questions about the nature of distortions in Kagome nets and their effects on superconductivity and magnetism.

Summary: Interlayer excitons are studied in hetero-bilayers of metal monochalcogenides, showing adjustable emission spectra and longer lifetimes compared to intralayer excitons. The bound electron-hole pair has a separation close to the calculated interfacial Se separation. These heterostacks have flat interfacial valence bands and are potential candidates for observing magnetism or other correlated electronic phases.

Summary: In this Perspective, the heuristic methods used to rationalize the stability of extended solids are discussed, with emphasis on the role of Goldschmidt's tolerance factor in perovskite research. The development of a tolerance factor for predicting the stability of intermetallic pseudoperovskites, the Remeika phases, and the correlation between oxidation states and valence fluctuation is also discussed. The feasibility of the Remeika phase tolerance factor is evaluated through the synthesis of a new predicted compound and measurement of its magnetic moment. The importance of determining the factors dictating the stability of Remeika intermetallics is highlighted.

Summary: This study developed an ultrasound-responsive polymer system that can degrade on demand when exposed to high-intensity focused ultrasound (HIFU). Diels-Alder cycloadducts were used to crosslink polycaprolactone (PCL) polymers and underwent a retro Diels-Alder reaction under HIFU stimulation. The relationship between reverse reaction energy barriers and polymer degradation rates was evaluated for two Diels-Alder polymer compositions. HIFU exposure time and amplitude were found to correlate with an increase in PCL degradation for Diels-Alder-based polymers. The study demonstrated that HIFU is an effective image-guided stimulus to control the degradation of Diels-Alder-based PCL polymers on-demand.

Summary: There is a growing interest in kagome materials, which provide tunable platforms combining magnetism and electron correlation. In this study, new kagome materials Ln(x)Co(3)(Ge1-ySny)(3) (Ln = Y, Gd; y = 0.11, 0.133) were examined using the Sn flux-growth method. The Y and Gd analogues have a hybrid YCo6Ge6/CoSn structure with Sn substitution. The Gd analogue displays a magnetic moment of 8.48 mu(B), indicating contributions from both Gd and Co, while the Y analogue exhibits temperature-independent paramagnetism. Anisotropic magnetic measurements suggest that the Co magnetism is in plane with the kagome net.
