Summary: Studies have shown that quercetin-coating on 3D-printed titanium alloy implants can enhance osseointegration and anti-inflammatory properties. In vitro experiments have demonstrated that the quercetin-coating can improve cell adhesion and osteogenic differentiation, as well as modulate macrophage polarization and the expression of anti-inflammatory genes. In vivo experiments have shown that quercetin-loaded implants can reduce peri-implant inflammation and promote new bone formation and rapid osseointegration.

Summary: In this study, new curcumin derivatives with improved anti-inflammatory activity were synthesized and evaluated. Thirteen derivatives were synthesized by Steglich esterification on the phenolic rings of curcumin, and the monofunctionalized compounds showed better bioactivity than the difunctionalized derivatives in inhibiting IL-6 production. Compound 2 exhibited the highest activity and also showed strong activity against PGE(2) synthesis. The structure-activity relationship analysis revealed that the presence of a free hydroxyl group or aromatic ligands on the curcumin ring, along with the absence of a linker moiety, contributed to the increased activity of this series of compounds.

Summary: In ancient times, herbal plants were highly valued for their medicinal uses, with mint being commonly used in traditional medicine. This study focuses on using mint leaf extract to synthesize safe calcium oxide (CaO) nanoparticles and evaluating their potential therapeutic applications. Various techniques such as UV-visible spectrophotometry, FTIR, SEM, DLS, and XRD were employed to examine the characteristics of the extracted CaO nanoparticles. Protein denaturation and nitric oxide scavenging assays, as well as MTT assays, were conducted to assess the therapeutic properties of the mint leaf mediated CaO nanoparticles. Additionally, the ability of these nanoparticles to act as photocatalytic agents was examined by studying their degradation of commonly used azo dyes in textile industries.

Summary: This study evaluated the antimicrobial activity of Arctostaphylos uva-ursi leaf extract against the main causative agent of acne vulgaris, C. acnes. The extract showed inhibitory effects on planktonic C. acnes and disrupted biofilm biomass formation. It did not affect the viability of human keratinocytes and inhibited the secretion of pro-inflammatory cytokines. These findings suggest that Arctostaphylos uva-ursi leaf extract could be a natural alternative for treating acne vulgaris.

This study introduces a new superior mechanical material called Gradia, composed of diamond and graphite nanodomains interlocked via coherent interfaces. Gradia exhibits sequential structural transitions under strain, leading to outstanding toughness. Furthermore, it has the potential to be a superhard material with estimated Vickers hardness exceeding 40 GPa. This work could be exemplary in exploring excellent mechanical materials through the modulation of carbon building block linking styles.

Summary: We conducted an extensive study on different B-P stoichiometries under pressure using a particle swarm optimization method and first-principles calculations. BP and B6P were found to be thermodynamically stable at 1 atm, while other stoichiometries were metastable. Under pressure, BP and B6P remained stable up to 80 GPa, while other stoichiometries became unstable at lower pressures. We predicted a new Cmca B6P structure with the lowest energy and higher shear strain than the R (3) over barm structure. Additionally, we found that the predicted Pm B8P is a magnetic semiconductor with a magnetic moment of 1 mu(B). All these boron-rich phosphides are hard materials. These results enrich the B-P phase diagram and promote extensive research on their excellent properties.

Summary: Controlling the magnetic anisotropy of ferromagnetic materials is crucial for the development of magnetic switching devices and spintronic applications. This study demonstrates the gate-tunable modulation of magnetic anisotropy in the van der Waals ferromagnet Fe5GeTe2, allowing for continuous rotation of the magnetic easy axis from an out-of-plane to an in-plane orientation. The results show that the modulation of anisotropy can be achieved via a spin-flop pathway and the range of modulation is significant, from 2.11 to -0.38 MJ m(-3). Additionally, temperature can also be used to tune the anisotropy.

Summary: Twin boundary (TB) is a special and fundamental internal interface that alters the mechanical and physical properties of materials. The deformation mechanism of TB and its effect on material strength and plasticity are still under debate. This study discovered that the pseudoelastic strain of a TB can recover with decomposition and escape of pile-up dislocations, which opens up new possibilities for optimizing material properties by manipulating twin boundaries at the nanoscale.

Summary: In this study, techniques such as scanning tunneling microscopy, X-ray photoelectron spectroscopy, angle-resolved photoemission spectroscopy, and aberration-corrected scanning transmission electron microscopy were used to validate the crystal structure of copper-rich boride Cu8B14 formed on the single crystal Cu (111) surface after depositing boron. First-principles calculations with defective surface models further showed that boron atoms tend to react with copper atoms near terrace edges or defects, resulting in the formation of intermediate structures and the eventual stable Cu-B monolayer through large-scale surface reconstruction.

Summary: The discovery of graphite-diamond hybrid materials (Gradia) has opened up a new direction in carbon allotropes research. In this study, Gradia-HZ, composed of interfaced graphite and hexagonal diamond parts, exhibited distinct electronic and mechanical properties. By modulating the graphite width, Gradia-HZ demonstrated unexpected topological nodal-line semimetal, semiconductor, and normal metal characteristics, along with a distinctive Quasi-1D electronic transport capability based on first-principles calculations. The discovery of unique physical properties in Gradia-HZ, such as high-conductivity metals, semiconductors with variable bandgap, and topological semimetals, will inspire further research and promote the development and application of graphite-diamond hybrid materials.

Summary: The application of high pressure accelerates the understanding of structure and exotic electronic states in transition metal dichalcogenides, leading to the discovery of intriguing phenomena. HfS2 exhibits tunable electronic properties under pressure, with a gradual narrowing of band-gap below 40 GPa, pressure-induced metallization above 40 GPa, and superconductivity starting around 115 GPa. The high Tc superconductivity induced by pressure is closely related to structural reconstructions and changes in electronic states near the Fermi surface.

Summary: The n-type indium and aluminum codoped PbTe material was prepared using high-pressure synthesis and spark plasma sintering. The Al doping provided a nearly constant carrier concentration with varying temperatures, while In doping trapped electrons at low temperatures and released them at high temperatures, thus optimizing the carrier concentration over a broad temperature range. As a result, both electrical transport properties and thermal conductivity were optimized, leading to a significantly enhanced thermoelectric performance in InxAl0.02Pb0.98Te. The optimal In0.008Al0.02Pb0.98Te showed a peak ZT of 1.3 and an average ZT of 1, with a decent conversion efficiency of 14%.
