Size-dependent Rigidities of Nanosized Torsional Elements
A theory for the prediction of the size dependence of torsional rigidities of nanosized structural elements is developed. It is shown that, to a very good approximation, the torsional rigidity (D) of a nanosized bar differs from the prediction of standard continuum mechanics (Dc) as (D−Dc)/Dc = Ah0/a where A is a non-dimensional constant, a is the size scale of the cross-section of the bar and ...
متن کاملPARTICLE SIZE CHARACTERIZATION OF NANOPARTICLES – A PRACTICALAPPROACH
Abstract: Most properties of nanoparticles are size-dependent. In fact, the novel properties of nanoaprticles do not prevail until the size has been reduced to the nanometer scale. The particle size and size distribution of alumina nanoparticle, as a critical properties, have been determined by transmission electron microscopy (TEM), photon correlation spectroscopy (PCS), surface area analysis ...
متن کاملSynthesis and photocatalytic activity of nanosized modified mesocellulous silica foams (MCFs) with PW12 and vanadium oxide
A series of tungestophosphoric acid and vanadium oxide supported on Mesocellulous Silica Foams (MCFs) featuring a well-defined three-dimensional (3D) mesoporosity were studied with regard to their performance in the photocatalytic activity to degrade Oezine Y (OY). This nanosized mesoporous catalyst (PW12@V-MCF) was characterized by FTIR, XRD, BET and TEM. XRD shows that the structure of MCF re...

متن کاملRaman Spectroscopy of Pharmaceutical Cocrystals in Nanosized Pores of Mesoporous Silica.
The Raman spectroscopy of pharmaceutical cocrystals based on caffeine and oxalic acid in nanosized pores of mesoporous silica has been demonstrated at various molar amounts. The Raman peak shifts of caffeine molecules express the existence of pharmaceutical cocrystals in mesoporous silica. The molar amount dependence of the peak shifts describes that caffeine and oxalic acid cocrystallized on t...
