Basic electrowetting theory predicts that a continued increase in applied voltage will allow contact angle modulation to zero degrees. In practice, the effect of contact angle saturation has always been observed to limit the contact angle modulation, often only down to a contact angle of 60 to 70. The physical origins of contact angle saturation have not yet been explained successfully and uneq...

Magnetite powder (FeO·Fe2O3 or Fe3O4) is obtained by the chemical precipitation method, using FeCl3·6H2O and FeCl2·4H2O as a starting materials in presence of hydrazine N2H4 at temperature 80 °C. X-ray diffraction analysis, infrared spectroscopy, scanning electron microscopy are used for study phase composition morphology synthesized powder. Its specific surface area magnetic properties such as...

Microorganisms, such as Pseudomonas putida, utilize specific physical properties of cellular membrane constituents, mainly glycerophospholipids, to (re-)adjust the membrane barrier to environmental stresses. Building a basis for membrane composition/function studies, we inventoried the glycerophospholipids of different Pseudomonas and challenged membranes of growing cells with n-butanol. Using ...

Due to their potential in numerous interdisciplinary fields, such as drug delivery, hyperthermia, and magnetic resonance imaging, nanoparticles have attracted widespread attention. In this study, cobalt ferrite are synthesized with varying amounts of iron ions, cytocompatibility is evaluated before after surface modification amino-silane (AEPTMS). Characterization the performed using scanning e...

Soil acidity has become a major yield-limiting factor, but it is unclear which indicator the best to use for estimating crop yield changes. In this study, four pH-adjusted Ultisols derived from different parent materials were used Chinese cabbage and wheat pot experiments. Structural equation modeling (SEM), Gompertz linear-plateau models examine main contribution of soil indices determine thei...

The extensive application of natural unbound granular materials (UGMs) motivates studies into the mechanical properties alternatives such as processed crushed rocks employed commonly base or subbase layers. rutting and settlement generated in layers is widely restricted many specifications standards. In this research, dynamic behavior including resilient modulus (Mr) plastic strain (??p) collec...
