BACKGROUND Aerosol lung administration is a convenient way to deliver water-insoluble or poorly soluble drugs, provided that small-sized particles are generated. Here, for the outbred male mice, we show that the pulmonary administration of ibuprofen nanoparticles requires a dose that is three to five orders of magnitude less than that for the orally delivered particles at the same analgesic eff...

Direct solar absorption has been often considered in the past as a possible solution for solar thermal collectors for residential and small commercial applications. A direct absorption could indeed improve the performance of solar collectors by skipping one step of the heat transfer mechanism in standard devices and having a more convenient temperature distribution inside the collector. Classic...

Introduction: Drugs and biocompatible nanoparticles have raised significant potential in advancing the bone regeneration. Electrospinning technology enables full realization of value drugs nanoparticles. Methods: In this study, we successfully fabricated core–sheath nanofibers solely composed polycaprolactone (PCL) polymer. Simvastatin (SIM) was confined to core while nanohydroxyapatite (nHA) l...

Magnetic properties such as coercivity, remanence and saturation magnetization will determine the area enclosed by hysteresis loop of a magnetic material, which also represents heating. Nanowarming cryopreserved organs is new application for heating using nanoparticles. In this paper, isolated Ni MNW different sizes shapes are studied via micromagnetic simulation to explore optimization individ...

Shielding properties of a cylindrical thick-walled ferrofluid layer that protects against externally applied uniform magnetic fields are numerically investigated. We take into account the diffusion nanoparticles in with dipole-dipole, steric and hydrodynamic interactions between particles. Permeability is considered to be dependent on magnetic-field strength particle concentration. A combined m...

In this study, the behavior of filament wound nanocomposite tubes under transverse impact loading is investigated. Experimental specimens were manufactured using Epon 828 resin with 0.5, 1.5 and 3 weight percentages of nano silica. Because of the varying nanosilica weight percentages in the specimens, different behaviors were observed; increasing the weight percentage of nanoparticles increased...

Background and aims. Polymethyl methacrylate, PMMA, is widely used in prosthodontics for fabrication of removable prostheses. This study was undertaken to investigate the effect of adding silver nanoparticles (AgNPs) to PMMA at 2% and 0.2% concentrations on compressive and tensile strengths of PMMA. Materials and methods. The silver nanoparticles were mixed with heat-cured acrylic resin in an a...

This report introduces QEPCAD B, a program for computing with real algebraic sets using cylindrical algebraic decomposition (CAD). QEPCAD B both extends and improves upon the QEPCAD system for quantifier elimination by partial cylindrical algebraic decomposition written by Hoon Hong in the early 1990s. This paper briefly discusses some of the improvements in the implementation of CAD and quanti...
