Novel uniform-sized, core-shell ZnO mesocrystal microspheres have been synthesized on a large scale using a facile one-pot hydrothermal method in the presence of the water-soluble polymer poly(sodium 4-styrenesulfonate). The mesocrystal forms via a nonclassical crystallization process. The intrinsic dipole field introduced by the nanoplatelets as a result of selective adsorption of the polyelec...

Halide perovskites are extremely interesting semiconductors for innovation in optoelectronics and photovoltaics. In particular, they efficient emitters of both incoherent coherent light and, therefore, interest as active materials lasers, amplification systems (resonators waveguides), other photonic devices. Here, we present a set experimental results concerning nonlinear effects the radiative ...

Microbubble technologies have recently gained acceptance as radiological molecular imaging or perfusion agents. These intravenous ultrasound contrast agents consist of gasfilled microspheres stabilized by a ‘shell’ layer which interfaces with a surrounding solvent pool. Development in the form of encapsulation with complex biocompatible polymer shell consisting of proteins, lipids and surfactan...

Ultrasonic spray pyrolysis was used in a continuous flow apparatus for the template-free synthesis of ironand nitrogen-doped porous carbon materials. Solutions of glucose, histidine and Fe(CH3COO)2 were nebulized and pyrolyzed yielding carbon microspheres. Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and Focused Ion Beam (FIB) milling revealed that microspheres initi...
