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...
angle(Harkes et al., 2008,Van Paassen, 2009,van Paassen et al., 2009,Airey and Duraisamy, 2012,Montoya and Dejong, 2015). It has been noted that the MICP method is more effective to maintain the original permeability of the natural soil. A number of studies have demonstrated that the...
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 ...
Experimental results indicated that the reduction in the contact angle following plasma treatment correlated with the elevated oxygen concentration and the presence of polar functional groups (e.g. -OH, -NH2, -NH3, C=O, O-C=O) on the composite surface. Plasma treatment, especially at low ...

also found that for a constant injection timing of 20 CAD (crank angle degree), the use of neat animal fat led to a decrease of maximum cycle pressure from 95 bar to 82 bar [5]. A biodiesel mixture of animal fat was used to fuel a diesel engine at full engine load, with the same...
Another at about 1000 Hz can be corresponding to the relaxation process of an adsorbed inhibitor film as a surface dielectric film normally has a small time constant and so has a phase angle shift in the high frequency range. The inhibitors film changes the electrode interfacial structure and ...
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 ...
