The development of novel electromagnetic materials for various applications largely depends on ferrite composites with optimal combination of constituent elements. The evaluation of their dielectric and magnetic properties is important in understanding the physical properties and potential for specific use. In this work, permittivity and permeability spectra of composite materials based on granulated...
Results of measurements of electromagnetic pulses with 3 to 10 mcs duration at frequencies 0.55 – 0.87 THz by the thermoacoustic detector1 are presented. Operation of the detector is based on effect of acoustic signal generation when electromagnetic pulses are absorbed in the layered structure: radiotransparent substrate - absorber - immersion liquid. Thin metallic film of nanometer thickness sputtered...

The goal of this study was to enhance gene delivery and tumor cell transfection in vivo by using a combination of ultrasonication with complex nanoparticles consisting of two types of nanoparticles: PEI/DNA β-gal plasmid with highly positive zeta-potential and air-filled poly (lactic-co-glycolic acid) (PLGA) particles (with negative zeta-potential) manufactured in our laboratory. The PLGA/PEI/DNA...
