The bond angle alteration can be explained by deviations from the trigonal hybridisation of the methine atoms. There exists a simple linear function between the square of the hybridisation parameter λ and the total charge densities calculated by means of the CNDO/2 method: λ2 ≅ 2 – Q.Dr...
Conclusion Structural investigations of nitramines in gen- eral show a relation between the N-N bond length and the torsion angle [26]. The torsion angles in nitramines with short N-N bond lengths are small. Nitramide is found to be planar in the crystal phase with an N-N bond length...
X-ray analyses of chain-shaped and of coupled polymethines show an enlargement of the bond angles of the positively charged methine atoms and a contraction of the bond angles of the negatively charged methine atoms. The bond angle alteration can be explained by deviations from the trigonal ...

Purpose: The aim of this study was to evaluate the TBS and the contact angle of experimental resin infiltrant materials doped with dimethyl sulfoxide (DMSO). Methods and Materials: Seventy bovine incisors were used for the TBS test. The roots of the teeth were removed, and the crown ...

During UV irradiation the phase angle of coating is changing as the structure of coatings is modified. The impedance spectra analysis was made using an equivalent electrical circuit (EEC) composed by a solution resistance (Rs), coating resistance (Rc), coating capacitance (Cc), double layer ...
The parameters studied included substrate temperature, Ar+ incident angle, Ar+ energy, and transitional effect of pulsing Ar+ flux. The observations indicate significant F atom uptake in HSQ pores after F atom exposure and no significant F atom uptake for blanket SiO2. These observations implied ...
