The purpose of this study was to separate and determine Nystatin in water, urine and plasma samples using a method based on sodium dodecyl sulfate (SDS) coated magnetic nanoparticles (nano-magnets Fe3O4) along with spectrophotometry which has been developed for to this end. Due to their excellent adsorption capacity and high chemical stability, nanoparticles can be modified by surfactants. The ...

background and objectives: biomaterials are widely used in medical devices such as urinary catheters. one of the main problems associated with long term using of the urinary catheters is biofilm formation on their surfaces. many techniques have been presented to reduce the biofilm formation. one of the most revolutionary techniques allowing such surface fictionalization is plasma surface modific...

The operation modes of a plasmatron for powder coating spraying have been studied. has node annular input and gasdynamic focusing the powder, outlet holes nozzle-anode are made in form rectangular narrowing-expanding channels (No.34334 RK: IPC H05H 1/42). dynamics trajectories particles were investigated. paper analyzes influence arc current working gas flow rate on structure properties obtaine...

Accelerating particles to high energies in plasma wakefields is considered be a promising technique with good energy efficiency and gradient. While important progress has been made plasma-based electron acceleration, positron acceleration scarcely studied fully self-consistent optimal scenario not yet identified. For physics applications where an electron-positron collider would desired, the ab...

Energy-efficient plasma-wakefield acceleration of particle bunches with low energy spread is a promising path to realizing compact free-electron lasers and colliders. High efficiency can be achieved simultaneously by strong beam loading plasma wakefields when accelerating carefully tailored current profiles [M. Tzoufras et al., Phys. Rev. Lett. 101, 145002 (2008)]. We experimentally demonstrate...
