The transfer of material from phospholipid-coated microbubbles to cell membranes has been hypothesized to play a role in ultrasound-mediated drug delivery. In this study, we employed quantitative fluorescence microscopy techniques to investigate this phenomenon in both artificial and biological membrane bilayers in an acoustofluidic system. The results of the present study provide strong eviden...

Azobenzene photoalignment materials are highly effective for liquid crystal alignment with high sensitivity and rewritability. A strong relationship between relative humidity and the alignment quality of a thin layer of azobenzenesulfonic dye has been investigated, where the photoinduced phase retardation, order parameter, and anchoring strength of the alignment layer are influenced dramaticall...

We present an experiment where subjects judged the relative complexity of 21 high-resolution building, room, and tabletop scenes, rendered with photorealistic methods. Scenes were gathered from web archives and va...

– We present first principles density functional calculations and downfolding studies of the electronic and magnetic properties of the layered quantum spin system TiOCl. We discuss explicitly the nature of the exchange paths and the concept of orbital ordering in this material. An analysis of the electronic structure of slightly distorted structures according to various phonon modes allowed in ...

Using x-ray absorption spectroscopy at the Ru-L2,3 edge we reveal that the Ru4+ ions remain in the S=1 spin state across the rare 4d-orbital ordering transition and spin-gap formation. We find using local spin density approximation + Hubbard U band structure calculations that the crystal fields in the low-temperature phase are not strong enough to stabilize the S=0 state. Instead, we identify a...

This paper presents a novel approach for automatically grading students’ answers to open-ended questions. It is inspired by the OeLE method, which uses ontologies and Semantic Web technologies to represent course material. The main difference in our approach is that we add a new category of concepts, named functional concepts, which allow specifying an ordering relation between concepts. This m...

1. Introduction Ordering in solid solutions is a topic of growing technological and scientific interest within the field of material science. This is because of the advantageous high temperature and corrosion properties of alloys which are linked to the effect of long-range ordering [1]. Long-range order kinetics is one of the diffusion processes occurring within the atomic ranges. X-ray diffra...
