Zr-Pd metallic glassy thin films with a hierarchical nano-scale structure, produced by magnetron sputtering of the Zr and Pd powder mixture, demonstrate a unique combination of physical and biochemical properties. Thermal stability of the nano-structured glassy samples, their resistance to oxidation in dry air and phase transformation behavior are discussed in the present work. These binary all...

The multi-scale microstructure of a lotus leaf is rendered non-wetting by micro-protrusions and nano-hairs present on its surface. The mechanical properties of the surface become important since the water droplet has to be supported on the micro-protrusions without wetting the surface. Current work correlates the non-wetting behavior of the lotus leaf with its mechanical properties (Young's mod...

Seeding nanoparticles in molten salts has been shown recently as a promising way to improve their thermo-physical properties. The prospect of such technology is of interest to both academic and industrial sectors in order to enhance the specific heat capacity of molten salt. The latter is used in concentrated solar power plants as both heat transfer fluid and sensible storage. This work explore...

This paper discusses the design and integration of a desktop system for electrohydrodynamic jet (E-jet) printing. E-jet printing is a micro/nano-manufacturing process that uses an electric field to induce fluid jet printing through micro/nano-scale nozzles. This enables better control and resolution than traditional jet-printing processes. The printing process is predominantly controlled by cha...

The enhancement of boiling heat transfer, the most powerful energy-transferring technology, will lead to milestones in the development of high-efficiency, next-generation energy systems. Perceiving nano-inspired interface functionalities from their rough morphologies, we demonstrate interface-induced liquid refreshing is essential to improve heat transfer by intrinsically avoiding Leidenfrost p...

Graphene is a novel material and currently popular as an enabler for the next-generation nanocomposites. Here, we report the use of graphene to improve the mechanical properties of nano-58S bioactive glass for bone repair and regeneration. And the composite scaffolds were fabricated by a homemade selective laser sintering system. Qualitative and quantitative analysis demonstrated the successful...

Hybrid opto-electric manipulation in microfluidics/nanofluidics refers to a set of methodologies employing optical modulation of electrokinetic schemes to achieve particle or fluid manipulation at the micro- and nano-scale. Over the last decade, a set of methodologies, which differ in their modulation strategy and/or the length scale of operation, have emerged. These techniques offer new opport...

The Enskog–Vlasov equation provides a consistent description of the microscopic molecular interactions for real fluids based on kinetic and mean-field theories. fluid flows in nano-channels are investigated by Bhatnagar–Gross–Krook (BGK) type model, which simplifies complicated collision operator enables large-scale engineering design simulations. density distributions found to exhibit inhomoge...

Recent development in nanoand biotechnology has opened a new field of microand nanofluidics. Many MEMS (micro-electro-mechanical-systems) and NEMS ( nano-electromechanical-systems ) are based on the fluid motion. Additionally, the analysis of biological samples, drug design and nanomedicine are connected to nanoliter fluid flow. The challenge for understanding such small systems lies in the dif...

Electro-osmotic flow, the driving of fluid at nano- or micro-scales with electric field, has found numerous applications, ranging from pumping to chemical and biomedical analyses in micro-devices. Electro-osmotic flow exhibits a puzzling hysteretic behavior when two fluids with different concentrations displace one another. The flow rate is faster when a higher concentration solution displaces ...
