Summary: High-pressure synthesis can create promising silicon allotropes, some of which have direct band gaps under tensile strain while others have narrow band gaps and good absorption properties. This study has discovered a new pressure-temperature pathway for producing silicon nanowires with transformative properties, opening up new possibilities for nanomaterial synthesis.

Summary: Magnesium- and silicon-substituted hydroxyapatite scaffolds were synthesized and evaluated for their microstructural, mechanical, and biological properties. Results showed that Mg and Si substitution led to improved mechanical properties and enhanced cell proliferation, with the HA-MgSi scaffold showing the most effective performance for cell adhesion and proliferation. Additionally, HA-Si and HA-MgSi scaffolds were found to promote osteoblast differentiation.

Summary: The study investigated the effects of varying properties of 1D barium titanate nanostructures on ion exchange processes and phase formation. It was found that BaTiO3 nano- and microrods with surface nanomaces and nanoparticle aggregates could be formed within specific temperature, time, and alkalinity ranges. X-ray diffraction and Raman spectroscopy analyses revealed improvements in material purity and phase composition control with increasing alkalinity and synthesis time.

Summary: Microwave-assisted hydrothermal synthesis of partially substituted silicon hydroxyapatite nanopowders was investigated. The experiments showed silicon incorporation into the hydroxyapatite lattice by replacing phosphate groups with silicate groups. Excess silicon content led to reduced particle growth and self-assembly of fine rod-shaped particles into agglomerates.

Summary: Novel hydrothermal methods assisted by hydroxyapatite were used to solidify heavy metals in fly ash, resulting in hydrothermally-treated products that meet landfilling standards. The solidification mechanism involved the formation of stable compounds between hydroxyapatite and heavy metal ions. The addition of hydroxyapatite seed crystal improved the solidification efficiency.

Summary: Si1-xGex nanowires (NWs) were prepared using a single-source precursor with preformed Si-Ge bonds through gold-supported chemical vapor deposition (CVD). The process reduces the control parameters associated with decomposition characteristics and dosing of individual precursors. The synthesized Si1-xGex/Au core-shell NWs exhibit metal-like behavior and show potential for applications in nano- and quantum-electronics.

Summary: Manganese doping is used to enhance bone regeneration by regulating adaptive immunity. It leads to increased recruitment of CD4+ T cells and promotes Th2 cell polarization while inhibiting Th1 cell polarization. This immune environment facilitates the osteogenic ability of bone marrow stromal cells and achieves consequential regeneration of mandibular bone defect.

Summary: This work presents the selective area epitaxy of GaN nanostructures grown on Ga-polar GaN/sapphire substrates by plasma-assisted molecular beam epitaxy. Three types of nanostructures, namely nanowires, nanofins, and nanorings, are demonstrated on GaN-on-sapphire templates, with investigation on the control of their morphology and orientation. This study advances the understanding of selective area epitaxy for defining complex III-nitride nanostructures, which are important in the fields of nanotechnology and nanoscience.

Summary: In this study, transmission electron microscopy was used to analyze the shape and internal strain of bent silicon nanowires prepared by asymmetric electron-beam evaporation. The results showed that asymmetric deposition of chromium led to the formation of nanosized amorphous silicon domains, and the non-crystallinity of the nanowires could be controlled by the bending radius.

Summary: This study presents a facile synthesis of bismuth and iron co-doped hydroxyapatite nanomaterials for high-performance fluoride ions adsorption. The nanomaterials exhibited excellent fluoride ion adsorption performance, as confirmed by batch adsorption experiments. The synthesized material showed a chemical process of fluoride uptake forming a monolayer, with homogenous surface. The proposed defluoridation mechanisms were electrostatic interaction and ion exchange. The ease of synthesis and the attractive fluoride adsorption performance make this nanomaterial promising for water treatment and environmental remediation applications.

Summary: Ion beam irradiation can manipulate the composition and shape of nanowires by causing crystal defects and volume expansions. The bending effect is observed in nanowires with different diameters, but remains largely unknown in nanowires with complex shapes influenced by non-uniform irradiation. Investigating TiO2 nanowires with bead-like and prismatic shapes under a Ga+ ion beam reveals significant bending only in prismatic nanowires, which can be reversed by changing the ion beam direction. This finding suggests that ion irradiation can be used to tailor the composition and morphology of nanowires at the nanoscale.
