Tuning bandgap and surface wettability of NiFe2O4 driven by phase transition

Tuning surface wettability through photocontrolled reversible molecular shuttle.

A photocontrolled molecular shuttle SAM based on an alpha-cyclodextrin (alpha-CD)/azobenzene inclusion complex on rough gold surfaces is fabricated, which can reversibly switch the surface wettability by transferring external energy (light) to molecular mechanical motion.

Early osseointegration driven by the surface chemistry and wettability of dental implants

OBJECTIVE The objective of this study was to investigate the impact of two different commercially available dental implants on osseointegration. The surfaces were sandblasting and acid etching (Group 1) and sandblasting and acid etching, then maintained in an isotonic solution of 0.9% sodium chloride (Group 2). MATERIAL AND METHODS X-ray photoelectron spectroscopy (XPS) was employed for surfa...

Two-Dimensional Open Microfluidic Devices by Tuning the Wettability on Patterned Superhydrophobic Polymeric Surface

We present a simple and economical method to produce a potential open microfluidic polymeric device. Biomimetic superhydrophobic surfaces were prepared on polystyrene using a phase separation methodology. Patterned two-dimensional channels were imprinted on the superhydrophobic substrates by exposing the surface to plasma or UV–ozone radiation. The wettability of the channels could be precisely...

Control surface wettability with nanoparticles from phase-change materials

Pressure-driven Quantum Phase Transition

The zero-temperature quantum phase transition (QPT) is driven by quantum fluctuations, in contrast to the more familiar finite temperature transitions driven by thermal fluctuations. This paper demonstrates our work on two kinds of QPTs in two different materials, respectively. The first work focuses on the pressure-driven antiferromagnetic QPT in pure chromium which is a model system for study...
