Design of a system for controlling a levitating sphere in superfluid 3He at extremely low temperatures [PDF]
We present a new mechanical probe to study the properties of superfluid 3He at microkelvin temperatures down to 100 μK. The setup consists of a set of coils for levitating a superconducting sphere and controlling its motion in a wide variety of regimes ...

Elastic and inelastic strain in submicron-thick ZnO epilayers grown on r-sapphire substrates by metal-organic vapour phase deposition. [PDF]
Sub‐micron a‐ZnO epilayers (12 to 770 nm) grown on r‐sapphire by MOCVD have been analysed using SEM, HRXRD, UPS, XPS and HRTEM. The distortion of the unit cell has been determined and the consequent strain shows a transition from an inelastic to an elastic state, separated by a critical thickness; a method to experimentally determine this critical ...

A Simple Microfluidic Device to Mitigate the Effect of Faradaic Reactions in Cross-Stream Particle Migration in DC-Electrokinetics [PDF]
Direct-current (DC) electrokinetics in microfluidic channels is inherently affected by Faradaic reactions at the electrode–electrolyte interfaces, which induce local changes in pH and conductivity and, consequently, alter particle behavior. In this work,
