A Fast Tunable 3D-Transmon Architecture for Superconducting Qubit-Based Hybrid Devices

Nano-graphene oxide, nano-(GO), was prepared via a modified Hummer’s method. Hence, superconducting composites of type (GO)_x/(Cu_0.25Tl_0.75)Ba₂Ca₃Cu₄O_12?δ, x?=?0.00, 0.25, 0.50, 0.75, 1.00, 1.50 and 2.00 wt%, were prepared via the solid-state reaction technique at 850 °C under ambient pressure. The prepared nano-(GO) was characterized using X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy, transmission electron microscopy, high-resolution transmission electron microscopy and the selected-area electron diffraction pattern. The composites samples of type (GO)_x/(Cu_0.25Tl_0.75)Ba₂Ca₃Cu₄O_12?δ were characterized using XRD and scanning electron microscopy. The electrical properties of the prepared samples were investigated using the electrical resistivity measurements. The results showed that the samples retained their superconductivity for all x values with a maximum enhancement in the phase formation, the superconducting transition temperature and the activation energy at x?=?0.75 wt%.

Effect of electrolyte nature in mass transport of a neutral solute in a microtube with porous wall

Electroosmotic flow in a microchannel is an active area in microfluidics. Microchannels with porous wall are advantageous due to selective separation and enhanced mass transport. An economic and innovative method to fabricate hollow microtubes and their application in electrokinetics are illustrated. Effects of asymmetric electrolyte on mass transport of a neutral macrosolute in the microtube with porous wall are investigated. The combined velocity profile including both pressure-driven and electroosmotic flow is modeled for different electrolytes. It is found from the study that the addition of higher valency asymmetric electrolyte (3:1) increases transport of neutral solutes across the porous wall compared to its symmetric counterpart (1:1). The developed model was validated with the experimental results, using a cartridge having hollow microtubes with porous wall. This study would be helpful to select an appropriate electrolyte, improving the design, and performance prediction of microfluidic devices.

Fabrication and characterization of hydrophobic thin polytrifluoroethyl methacrylate adhered coating on cotton surface via amicellar polymerization

In this study, fluorine-based methacrylate ester monomers were polymerized on cotton fabric by admicellar polymerization to make the cotton surface highly rough and also highly hydrophobic with a reliable water contact angle value. The rough micro/nano-textured surface morphology, after surface fluorination, results in hydrophobicity. The hydrophobic character was confirmed by a simple drop test and contact angle measurements. Surface composition was evaluated by SEM and FT IR analysis to confirm the fluoropolymeric layer adhered on the cotton surface.     

Development of Multiphase Microstructure with Bainite, Martensite, and Retained Austenite in a Co-Containing Steel Through Quenching and Partitioning (Q&P) Treatment

The quenching and partitioning (Q&P) treatment of steel aims to produce a higher fraction of retained austenite by carbon partitioning from supersaturated martensite. Q&P studies done so far, relies on the basic concept of suppression of carbide formation by the addition of Si and/or Al. In the present study Q&P treatment is performed on a steel containing 0.32 C, 1.78 Mn, 0.64 Si, 1.75 Al, and 1.20 Co (all wt pct). A combination of 0.64 Si and 1.75 Al is chosen to suppress the carbide precipitation and therefore, to achieve carbon partitioning after quenching. Addition of Co along with Al is expected to accelerate the bainite transformation during Q&P treatment by increasing the driving force for transformation. The final aim is to develop a multiphase microstructure containing bainite, martensite, and the retained austenite and to study the effect of processing parameters (especially, quenching temperature and homogenization time) on the fraction and stability of retained austenite. A higher fraction of retained austenite (~13 pct) has indeed been achieved by Q&P treatment, compared to that obtained after direct-quenching (2.7 pct) or isothermal bainitic transformation (9.7 pct). Carbon partitioning during martensitic and bainitic transformations increased the stability of retained austenite.     

Sherwood number in flow through parallel porous plates (Microchannel) due to pressure and electroosmotic flow

An expression for Sherwood number is developed from first principles for combined pressure‐driven and electroosmotic flow in a porous rectangular microchannel. This quantifies the mass transfer of an electrically neutral solute in the microchannel and is useful for designing microfluidic devices and porous media flows. The convective‐diffusive species balance equation, coupled with the velocity field, is solved within the mass transfer boundary layer utilizing similarity method. From the simulations, it is observed that the Sherwood number increases as the electric double layer near the channel wall becomes more compact (as manifested through a decrease in the Debye length), and it reaches a constant value around the scaled Debye length of 40. The Sherwood number becomes constant at higher Debye lengths as electrokinetic effects become negligible. A detailed analysis of dependence of Reynolds number, dimensionless permeation velocity, ratio of driving force and scaled Debye length on Sherwood number is presented. © 2011 American Institute of Chemical Engineers AIChE J, 58: 1693–1703, 2012
