Summary: This study demonstrates the selective stabilization of all insulating phases in single-crystalline VO2 beams at room temperature through oxide inhibitor-assisted stoichiometry engineering. The precise spatial control of phase configurations introduces a new concept of phase transition route devices. By combining different phase transition routes, high-performance VO2 actuators with improved performance and functional diversity are achieved.

Summary: A solution growth method for high-quality single-crystalline fibers (SCFs) is reported, in which tetraphenylphosphonium bromide (TppBr) SCFs with highly anisotropic surface micromorphology are successfully produced at room temperature. The defect-free TppBr SCF seed grows rapidly along 1D direction, while its prismatic growth is completely suppressed.

Summary: Although the general applicability of the Weibull distribution for micro/nanostructures has not been established, recent research shows that the distribution can accurately describe the probability of failure even for structures containing as few as 6 elements as long as the Weibull modulus is greater than 2. New equations have been derived to calculate the representative volume from strength data, allowing for better comparisons with observed defects in materials like graphene and polysilicon.

Summary: Engineering anisotropic nanostructures of isotropic FCC metals like Au, Pt, or Pd requires a symmetry-breaking mechanism and a judicious selection of capping agents. The formation mechanism of ultrathin single-crystalline Pt nanowires was investigated using electron microscopy, showing that ligand binding to the Pt surface plays a crucial role in morphology and growth direction control. Adopting a ligand-exchange mechanism can separate Pt nanowire bundles into individual wires, crucial for improving their electrocatalytic activity.

Summary: A new method using chemical vapor deposition (CVD) with K2WS4 as growth precursor was developed for the growth of large and high-quality WS(2) monolayers, achieving a fast growth rate and high electrical performance. The obtained WS(2) flakes were 2D single crystals with low defect density, demonstrating the potential for producing high quality 2D semiconductors for future nanoelectronics.

Summary: Single-crystalline iron silicide nanowires were successfully synthesized using the pre-deposition method, showing significantly improved morphologies and physical characteristics without the need for a catalyst or template. The alignment and aspect ratio of the nanowires were considerably enhanced, and the beta-FeSi2 nanowires synthesized by the PDM outperformed those made by conventional CVD in terms of field emission and magnetic properties.

Summary: The scalable synthesis of van der Waals vertical heterostructures is important for the fabrication of novel 2D-based functional applications. Combining graphene with transition metal dichalcogenides shows potential for exploring new device architectures with unique functionalities. Experimental results reveal how the properties of the graphene template influence the growth of tungsten selenide, such as nucleation site density, growth rate, orientation, and thickness.

Summary: Tungsten has been studied as a potential plasma facing material for future fusion reactors, with research focusing on the effects of helium ion-beam irradiation on different crystallographic orientations. The results show that radiation damage, helium thermal desorption, and surface/subsurface evolution are all strongly influenced by crystallographic orientation in tungsten. The findings provide new insights into the behavior of helium in tungsten materials.

Summary: The study shows that helium ion irradiation can produce 111-oriented surface grains on tungsten, which plays a crucial role in the surface and subsurface evolutions of tungsten in fusion-relevant service environments. The orientation relationship between irradiation-induced new surface grains and single-crystalline tungsten matrix was investigated, and the results suggest that most 111-oriented surface grains can be regarded as the grain rotation of the matrix around its in-plane 110 axis.

Summary: The dynamic crystal lattice of halide perovskites facilitates the coupled transport of ions and electrons, offering innovative concepts in semiconductor iontronic devices. This study focused on investigating electric field induced ionic transport in CsPbBr3 nanowires and discovered highly anisotropic ionic transport upon poling. The giant switchable photovoltaic effect was identified, along with significant localization of photocarriers near one terminal of the device, attributed to the accumulation of halogen vacancies. The poled device showed a 10-fold increase of photoresponse speed due to enhancement of the local electric field.

Summary: This study investigates the mechanical properties and fracture mechanisms of GaAs nanowires under tensile stress, revealing that they deform elastically overall until sudden brittle fracture at 3.79% strain. Experimental results show fracture strength and elastic modulus of 4.0 and 109.5 GPa, respectively, which are much smaller than previous compression-based reports.

Summary: Understanding the electrochemical reaction process of electrodes is crucial for developing high-performance materials. The study investigated the sodium ion storage behavior and mechanism of orthorhombic V2O5 single-crystalline nanowires, demonstrating large irreversible capacity loss in the first cycle but excellent cycling stability in subsequent cycles. The diffusion coefficient of Na+ in the material was evaluated to be in the range of 10(-12) to 10(-11.5) cm(2)s(-1) by galvanostatic intermittent titration technique (GITT).
