Chlorides of NH₄Cl and SrCl₂ and fluorides of AlF₃ and SrF₂ were added to raw materials acting as the flux for preparing the SrSi₂O₂N₂:Eu2+ phosphor. The effects of the fluxes on the phase formation, particle morphology, particle size, and photoluminescence properties were investigated. The results revealed that particle size, particle morphology and photoluminescence intensity were largely dom...

the lead ferrite (pbfe12o19) nanoparticles were prepared by a simple and short time microwave method. lead nitrate, iron nitrate hydrate, surfactants, and ethylene glycol were used as precursor materials. the effect of surfactants on the morphology and particle size of the magnetic products was investigated. the prepared magnetic products were study by x-ray diffraction (xrd), scanning electron...

Nanostructured Cu-20Fe alloy was synthesized by mechanical alloying process and the effects of process control agents (PCA) on the phase formation, crystallite refinement and morphology of powder particles were studied. The dissolution of Fe into Cu matrix and the morphology of powder particles were analyzed by X-ray diffraction (XRD) technique and scanning electron microscopy (SEM), respective...

Both the pore size and particle diameter of aqueous colloidal mesostructured/mesoporous silica nanoparticles (CMSS/CMPS) derived from tetrapropoxysilane were effectively and easily controlled by the addition of trialkylbenzenes (TAB). Aqueous highly dispersed CMPS with large pores were successfully obtained through removal of surfactants and TAB by a dialysis process. The pore size (from 4 nm t...

The conversion of lignocellulosic biomass into fine chemicals and polymers has been gaining attention recently. Regenerated lignocellulose beads (RLBs) were prepared by an emulsification/precipitation technique, using wheat straw as a raw material and [Bmim]Cl as a solvent. The morphology and properties of the obtained beads were characterized. The RLBs were perfectly spherical, with a porous m...

In this paper, using concepts from the nonstandard physical world, the linear effect line element is derived. Previously, this line element was employed to obtain, with the exception of radioactive decay, various experimentally verified special theory relativistic alterations in physical measures. This line element is now used to derive, by means of separation of variables, an expression that p...

Hysteresis patterns of different sediment particle sizes were studied via a detailed laboratory study and modelling. Seven continuous rainfall events with stepwisevarying rainfall intensities (15, 30, 45, 60, 45, 30 and 15 mmh-1, each 20 min duration) were conducted using a 5-m× 2-m erosion flume. Flow rates and sediment concentration data were measured using flume discharge samples, and interp...

This tutorial review is intended to provide an accessible and self-contained introduction to the discipline of electromagnetic scattering by nonspherical particles and discuss the most general ways in which the scattering and absorption properties of particles and small random particle groups are affected by particle morphology. The main focus is on how nonsphericity influences our way of descr...

This book is about those Germanic verbal constructions variously referred ...

Similar to the electron, the muon is an elementary particle classified as a lepton with a negative charge and half-spin. Naturally-occurring muons are created due to cosmic rays and travel at relativistic speeds and thus feel the effects of time dilation. Due to this the lifetime of the muon is heavily dependent on the speed at which it is moving. We will discuss the lifetime and decay of the m...
