Porous carbon materials have extraordinary importance as electrodes in many electrochemical devices used for energy storage and conversion. For this reason, there is a growing interest the design of new with improved chemical structural properties that enhance their performance providing high power densities well long cyclability. To satisfy demand, researchers are continuously looking types fu...

Carbon nanotubes (CNTs), graphene (GA) and carbon nanospheres (CNSs) were prepared respectively using grass (Festucaarundinace) as the sole carbon resource by solvothermal method and characterized as adsorbent and photocatalyst for 2-chlorophenol (2-CP) removal in water. With H2O2/HNO3/H2SO4, the CNTs were firstly produced from grass (Festucaarundinace) at 300 °C by hydrolysis and oxidization, ...

  Objective(s): The purpose of this study was preparation and evaluation of PLGA nanospheres containing the influenza virus and different adjuvants, Quillaja saponin (QS) and CpG-ODN.   Materials and Methods: Nanospheres were prepared using the double emulsion-solvent evaporation method. The morphological and physicochemical properties were studied by scanning electron microscopy...

Mesoporous bioactive glass (MBG) nanospheres with excellent drug loading property have attracted significant attention in the field of nano-medicine. However, systemic metabolism and biosafety of MBG nanospheres which are crucial issues for clinical application are yet to be fully understood. Isotope quantitative tracing combined with biochemical parameters and histopatological changes were use...

Potent immunoadjuvants are needed to elicit responses following mucosal delivery. PLGA (poly[D,L-lactic-co-glycolic acid]) nanospheres, Quillaja saponin (QS) and cross-linked dextran microspheres (CDM) as drug delivery and absorption enhancer adjuvants were evaluated. PLGA nanospheres were prepared by solvent evaporation method. Particulate characteristics of nanospheres were studied by optical...

This paper reports a high-yield synthesis of Ag nanospheres made up of primary nanoparticles. The size of the silver nanospheres can be controlled by changing the concentration of poly(vinylpyrrolidone) (PVP) which acts as a stabilizer. In addition, the surface morphology of the nanospheres can be well controlled through controlling the shape of primary Ag nanoparticles by introducing a small q...
