We propose a simple method for determination of polar anchoring coefficient by electrical measurements. The basic idea of this method is a two-channel scheme for capacitance measurements. The first channel uses one cell with planar alignment LC, the second channel uses the cell with vertical alignment (VA). Such method gives a possibility to investigate anchoring properties of planar and vertic...

The investigation of vertical channel deformations the main rivers Teteriv basin over last 40 years according to data 6 hydrological stations was carried out. prerequisite for this establishment trends in changes water discharge considered watercourses. A general decrease these indicators, especially average and maximum flow revealed. This is confirmed by previously conducted studies on level f...

The quality of channel sidewalls resulting from through-wafer deep reactive-ion etching is analysed using scanning electron microscopy, atomic-force microscopy and interferometry. Sidewall quality and profile are highly dependent on the width of the etched channel. Channels narrower than 100 lm show generally good sidewall smoothness, though with a bowed profile. This profile leads to ion-induc...
