Nanopatterns have applications in many areas including sensors, optoelectronics, and crystallization screening. Particle lithography is a convenient method to manufacture nanoring nanopatterns based on organosilane surface chemistry. The pattern thickness is generally limited to the monolayer thickness. This work is focused on the chemical vapor deposition conditions that yield nanopatterns wit...

In this work we present a microwave intracavity sensor for the characterization of aqueous solutions nano-liter sessile droplets, deposited on microstrip line electrode. The operates at frequency and is based tunable magnonic delay oscillator. samples were characterized by using their evaporation dynamics, measuring dielectric constants. experiments have shown that capable detecting salinity (S...

There is an increasing trend among pharmaceutical industries to use natural bioactive materials as medicinal agents and to use new technologies such as self-nanoemulsifying systems. The solubility and bioavailability of poorly soluble drugs can be enhanced by self-nanoemulsifying systems. Swietenia oil is frequently used because of its antimicrobial, antimutagenic, and anticancer bioactive medi...

PURPOSE The aim of study is to investigate role of co-surfactant in self-emulsification through rheological analysis of intermediate liquid crystalline (LC) phase formed during self-emulsification. METHODS To mixture of Captex 200P (C200) and tween 80 (T80) (SES Plain), either medium hydrocarbon chain co-surfactant (Capmul MCM (CMCM): SES C) or long hydrocarbon chain co-surfactant (Peceol (P)...

Au deposition on Si(110) at temperature higher than 633 K leads to the formation of elongated liquid nano-droplets. In this work we show that under an electric field, droplets move along [1–10] axis towards positive electrode by electromigration. During motion, they dissolve substrate forming a hole underneath and nanowire behind them. We develop model highlighting driving force these processes...

To resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies.  The assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process ...
