Abstract Continuous gas-phase synthesis of nanoparticles is associated with rapid agglomeration, which can be a limiting factor for numerous applications. In this report, we challenge paradigm by providing experimental evidence to support that methods used produce ultrapure non-agglomerated “singlet” having tunable sizes at room temperature. By controlling the temperature in particle growth zone guarantee complete coalescence colliding entities, size singlets principle regulated from single...
Metallized arrays of three-dimensional (3D) nanoarchitectures offer new and exciting prospects in nanophotonics nanoelectronics. Engineering these repeating nanoarchitectures, which have dimensions smaller than the wavelength light source, enables in-depth investigation unprecedented light-matter interactions. Conventional metal nanomanufacturing relies largely on lithographic methods that are limited regarding choice materials machine write time restricted to flat patterns rigid structures....
Among the numerous point vapor sources, microsecond-pulsed spark ablation at atmospheric pressure is a versatile and environmentally friendly method for producing ultrapure inorganic nanoparticles ranging from singlets having sizes smaller than 1 nm to larger agglomerated structures. Due its fast quenching extremely high supersaturation, coagulational growth already begins atomic scale room temperature. On basis of this knowledge, we develop simple semiempirical yet model predicting size...
System miniaturization is a key driver in developing nanoelectromechanical systems, sensors, and microchips. To enhance reliability extend operational lifetimes, high-entropy alloys (HEAs) have emerged as promising materials due to their exceptional mechanical robustness thermal stability. These advantageous properties are predominantly demonstrated bulk HEA forms; however, research on small-dimensional HEAs largely confined nanoparticles, nanopillars, thin films, limiting broader...
Abstract 3D nanoprinting presents a fundamentally different approach (bottom‐up) compared to traditional nanolithography (top‐down), enabling the fabrication of nanostructures with greater material versatility and complex spatial geometries. Initially developed for macroscopic devices fabrication, printing is now progressing toward nanodevices production active functionalities. This review explores cutting‐edge technologies nanoscale materials, emphasizing key achievements, foundamental...
Cloud operations and services, as well many other modern computing tasks, require hardware that is run by very densely packed integrated circuits (ICs) heterogenous ICs. The performance of these ICs determined the stability properties interconnects between semiconductor devices Although some with 3D are commercially available, there has been limited progress on printing utilizing emerging nanomaterials. Moreover, laying out reliable metal in appropriate electrical physical remains...
A major challenge in nanotechnology is that of determining how to introduce green and sustainable principles when assembling individual nanoscale elements create working devices. For instance, textile nanofinishing restricted by the many constraints traditional pad-dry-cure processes, such as use costly chemical precursors produce nanoparticles (NPs), high liquid energy consumption, production harmful wastes, multistep batch operations. By integrating low-cost, scalable, environmentally...

Using the magnetocaloric effect in nanoparticles holds great potential for efficient refrigeration and energy conversion. The most promising candidate materials tailoring Curie temperature to room are rare-earth-based magnetic nanoalloys.
