The hydrolysis of a bridged alpha,omega-bis(trialkynylstannylated) compound leads to a hybrid material ordered by self-assembly where the spacer forms two six-membered [1,2]oxastanninane rings by intramolecular coordination.

abstract   statement of problem: hertzian indentation test has been proven to be an efficient and reliable alternative upon vickers hardness test. this method has been used to test dental ceramics, amalgams, glass ionomers and luting cements.there is limited published information about the load-bearing capacity of resin composites using hertizian indentation test. objectives: to investigate the...

We begin by reviewing a technique to approximate the dynamics of stochastic programs—written in a stochastic process algebra—by a hybrid system, suitable to capture a mixed discrete/continuous evolution. In a nutshell, the discrete dynamics is kept stochastic while the continuous evolution is given in terms of ODEs, and the overall technique, therefore, naturally associates a Piecewise Determin...

during the last decades a new class of materials named fiber/metal laminates (fmls) was introduced. it is a hybrid composite consisting of alternating thin layers of metal sheets and fiber-reinforced composite material. fmls have both low weight and good mechanical properties. in this study, the impact behavior of this attractive material is investigated. the effect of fiber angle, stacking seq...

SINGLE CRYSTALS OF THE NEW TITLE COMPOUND [SYSTEMATIC NAME: 1,4,7,10-tetra-zoniadecane hexa-chloridorhodate(III) chloride], [H(3)N(CH(2))(2)NH(2)(CH(2))(2)NH(2)(CH(2))(2)NH(3)][RhCl(6)]Cl, were obtained from the corresponding amine and rhodium trichloride in hydro-chloric acid solution by slow crystallization under diffusion-controlled conditions at room temperature. Its solid-state structure i...

We investigate a new mean of decreasing leakage and material loss from coaxial cables using different metallic shield and central conducting part geometries. The suggested model is composed of a central conductor surrounded by 40 metallic wires circularly disposed. The proposed cable is also a hybrid one allowing simultaneous transmission of optical as well as radio frequency (RF) signals. The ...

Herein we demonstrate a new, straightforward method for the synthesis of macroporous hybrid polymers coated with gold nanorods, which are strongly and uniformly attached to the surface of pores.

Carbon nanotubes are of great interest due to their high surface area and rich edge sites, which are favorable for wide applications. Here, a simple and efficient routine is presented by decoration of multi-wall carbon nanotube (MWCNT) with nickel oxide (NiO) nanoparticles.The morphologies of NiO-MWCNT  were  investigated  by  using scanning  electron  microscope  (SEM)  and energydispersive X-...

In this study, highly ordered mesoporous silica material (SBA-15) functionalized with Diethyl 2 - (9 -fluorenyl) malonate as a flourophore is reported. The anchoring of flourophores to the hydroxyl group on SBA-15 surface was done with post synthesis method. The obtained materials were characterized by small and wide angle X-ray diffraction, N2 adsorption–desorption, Fourier transform infrared ...
