Spark ablation is a versatile technique for producing pure size-selected nanoparticles. The carrier gas used in spark affects the nanoparticles' generation, crystalline structure, and chemical composition. comprehension of this phenomenon can contribute to design nanoparticles with tailored properties. In paper, we evaluate effects reducing (95%N2 + 5%H2), inert (N2), oxidative (air) gases setup Co–Ni alloyed electrodes. agglomerates' particle size distribution, morphology, composition were...
Mixed nanoparticles at atomic scale have been synthesized by atmospheric-pressure spark ablation using different combinations of electrode diameters–polarities.
Metal oxide nanoparticles are essential in various applications, and the synthesis through gas-phase generation methods offers a rapid reliable pathway for nanoparticle production. Yet achieving precise control over their formation remains challenging due to complex nature of oxidation processes. While bulk states can be assessed via off-line measurements, dynamic surface is more difficult monitor optimize real time. Here, we investigate state unsupported tin using an aerosol sample-delivery...
In the last decades, metal‐assisted growth approach of semiconductor nanowires (NWs) has shown its potential in controlling crystal properties, such as structure, composition, and morphology. Recently, literature reports have successful NW with multiphase seed particles under conditions. Exploring alternative metal seeds mechanisms for growing NWs is an exciting research field aiming to improve control over process. Herein, gallium phosphide (GaP) using Cu inside environmental transmission...
This work reports on a novel template-free technique for producing isolated 1D magnetic nanochains and nanowires directly onto substrates device architectures by directed self-assembly of gas-phase-generated nanoparticles.
Multimetallic nanoparticles possess a variety of beneficial properties with potential relevance for various applications. These metallic can consist randomly ordered alloys, which retain the constituting elements, or intermetallics, extended properties. Depending on desired application, specific alloys intermetallic compounds are required. However, it remains challenging to achieve particular morphologies, crystal structures, chemical compositions, and particle sizes because inherent...
Tailored Pd–Cu nanoparticles by spark ablation with a broad compositional range. X-ray spectroscopy and electron microscopy were used to show dynamic synthesis, successful mixing, insights for development of new catalysts.
Abstract Cuprate coated conductors are promising materials for the development of large-scale applications, having superior performance over other superconductors. Tailoring their vortex pinning landscape through nanostructure engineering is one major challenges to fulfill specific application requirements.

High-performing superconducting YBa2Cu3O7–x (YBCO) films are fabricated by a chemical solution deposition methodology through novel barium-deficient low-fluorine solutions. The precursor solutions, distinguished for being straightforward, inexpensive and eco-friendly, allow us to reduce the growing temperature of YBCO down 750 °C. We investigated influence temperatures on both microstructure properties using conventional thermal annealing flash-heating approaches. A clear correlation between...
