In complex cases of enamel fluorosis or enamel dys-mineralization, combined bleaching and micro-abrasion therapies may be advocated. The aim of the present study was to investigate the effect of combined in-office bleaching and micro-abrasion on the bond strength of two dental adhesives bonded to surface enamel. The interfacial micro-morphology of the involved surfaces was also studied by using...

We report on the measurement of morphology-dependent resonance within a laser-trapped micro-sphere excited under two-photon absorption. Both trapping and two-photon excitation are simultaneously achieved by a single femtosecond pulsed laser beam. The effect of the laser power as well as the pulse width on the transverse trapping force is first investigated. The dependence of two-photon-induced ...

Microwave-assisted hydrothermal synthesis was used to grow LiMnPO4 micro- and nanocrystals from acetate precursors. By appropriate adjustment of the precursor concentration and the pH-value of the reactant, the product composition and purity along with the crystal size can be manipulated, resulting in particle-dimensions from around 10 μm down to a few 100 nm. Prisms and plates with hexagonal b...

Introduction: The Moon is being considered as an effective test-bed and fueling station for future space missions to Mars and beyond, with In-Situ Resource Utilization (ISRU) of lunar materials [1]. From the Apollo missions, however, it is well known that dust on the Moon can cause serious problems for human’s exploration activities [2]. One of the paramount problems is the potential for a toxi...

Although the microstructure of coexistence phase provides direct insights of the nucleation mechanism and their change is substantial in the phase transition, their study is limited due to the lack of suitable tools capturing the thermodynamically unstable transient states. We resolve this problem in computational study by introducing a generalized canonical ensemble simulation and investigate ...

On the other hand, there is much evidence that human listeners are sensitive to the internal structure of words, particularly to that related to their meaning, or morphology. Some evidence for this is just to do with the production and interpretation of novel, morphologically complex words such as “un-micro-wave-ability”. But there is also interesting psycholinguistic evidence that morphologica...
