The morphology, crystallinity, and electrical conductivity (σ′ σ″) as a function of frequency polypropylene (PP) melt-extruded with different amounts as-grown carbon nanofibers (CNFs) from 0 to 1.4 vol. % are examined. PP/CNF composites present CNF aggregates randomly distributed within the PP an insulator–conductor transition at contents near 0.9 %. degree crystallinity loadings increases ∼15%...

Let A be a Banach algebra and X be a Banach A-bimodule. In this paper, we define a new product on $Aoplus X$ and generalize the module extension Banach algebras. We  obtain characterizations of Arens regularity, commutativity, semisimplity, and study the ideal structure and derivations of this new Banach algebra.

A signed graph is an ordered pair Σ=(G,σ), where G a and σ:E(G)⟶{+1,−1} mapping. For e∈E(G), σ(e) called the sign of e for any sub-graph H G, σ(H)=∏e∈E(H)σ(e) H. having each cycle +1 balanced. Two vertices in are antipodal if dG(u,v)=diam(G). The A(G) with vertex set that same as two u,v adjacent antipodal. By d-antipodal GdA we refer to union A(G). Given ΣdA=(GdA,σd) σd defined follows: σd(e)=...

In this research at the first fluoxetine drug and its fullerene derivative were optimized. NBO calculations and NMR for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemical hardness (η), Thermodynamic Properties was determi...

In the present study, the cooperative and diminutive interplay between halogen, hydride, and cation-σ interactions are studied in HMgH···Li+(Na+)···NCCl, Li+(Na+)···HMgH···ClCN and HMgH···ClCN···Li+(Na+) complexes by means of ab initio calculations. To better understand the cooperative or diminutive effects in the ternar...
