Summary: The integration of dissimilar materials into heterostructures is a main focus in modern materials science and technology. By combining 1D nanowires and 2D plates, mixed-dimensional heterostructures can be created with varying composition and dimensionality, resulting in larger contrast in electronic structures. Previous methods required multi-step growth processes, but this study demonstrates a single-step growth process using differences in precursor incorporation rates to synthesize mixed-dimensional heterostructures. This new approach opens up possibilities for complex heteroarchitectures.

Summary: This work proposes a new architecture of photoelectrodes consisting of supported multishell nanotubes fabricated by a soft-template approach. The obtained NT electrodes have a large electrochemically active surface and outperform the efficiency of equivalent planar-layered electrodes by more than one order of magnitude. The characteristics of the WO3/BiVO4 Schottky barrier heterojunction control the NT electrode efficiency, which depends on the BiVO4 outer layer thickness and the incorporation of the CoPi electrocatalyst, as demonstrated by thorough electrochemical analysis.

Summary: The formation of monoclinic VO2 crystal domains at low temperatures in nanocolumnar vanadium/oxygen thin films deposited via magnetron sputtering is analyzed. The synthesis involved depositing amorphous nanocolumnar VO1.9 thin films at room temperature and annealing them at temperatures between 250 - 330 ? in an oxygen atmosphere. The nanocolumnar structures exhibited a thermochromic transition at 47 ? (for annealing at 270 ?) and 58 ? (for annealing at 280 and 290 ?), resulting in a significant drop in optical transmittance in the infrared region.

Summary: This paper studied the morphology and void connectivity of thin films grown by magnetron sputtering deposition at oblique geometries. A well-tested thin film growth model was used, along with experimental data, to assess the features of these layers. The film morphology and pore topology varied significantly with the growth conditions, which were linked to the different collisional transport of sputtered species in the plasma gas. Four different film morphologies were identified, and their porous network characteristics were described, explaining their potential applications in electrochromic sensors or infiltration with nanoparticles.

Summary: By using an adamantane plasma polymer pinning layer, we achieve unprecedented crystal strains of 2.8% in monolayer molybdenum disulfide. The strain gauge factors for the A and B excitons of monolayer MoS2 are reported as -99.5 meV/% and -63.5 meV/%, respectively, with a 50 nm adamantane capping layer. Photoluminescence and Raman measurements on the same samples confirm these results. Overall, our study demonstrates that adamantane polymer is an exceptional capping layer for transferring substrate-induced strain to a 2D layer and achieving higher levels of crystal strain.

Summary: In this study, a novel methodology of plasma-assisted thin film structuration was proposed by combining piezoelectric AWs and plasmas during the growth of a thin film. SiO2 and SiOx (x<2) thin films were deposited by magnetron sputtering at oblique angles (MS-OAD) on an electro-acoustically excited LiNbO3 piezoelectric substrate under resonant conditions. The resulting films exhibited 2D patterned microstructure with submillimeter size intermingled zones, which replicated the distribution of polarization potential on the AW activated substrate immersed in the plasma. The main mechanism responsible for the appearance of domains with different morphology and chemical composition was found to be the focused impingement of Ar+ plasma ions on certain regions of the substrate. The discussed the general character of this patterning process, the underlying physics, and its possibilities to tailor the composition and microstructure of dielectric thin film materials.

Summary: This work investigates the influence of the optical environment on the radiative decay rate of rare-earth transitions in luminescent nanoparticles forming a thin film, both theoretically and experimentally. By using finite-difference time-domain simulations and experiments, we propose modifications to existing analytical models for calculating the radiative decay rate and successfully achieve gradual and controllable alteration of the effective refractive index in luminescent films. Our research provides valuable insights for the rational tuning of the spontaneous decay rate and photoluminescence quantum yield in luminescent nanoparticle ensembles.
