Let $R$ be a commutative ring and $mathbb{A}(R)$ be the set of all ideals with non-zero annihilators. Assume that $mathbb{A}^*(R)=mathbb{A}(R)diagdown {0}$ and $mathbb{F}(R)$ denote the set of all finitely generated ideals of $R$. In this paper, we introduce and investigate the {it finitely generated subgraph} of the annihilating-ideal graph of $R$, denoted by $mathbb{AG}_F(R)$. It is the (undi...

Objective(s): To evaluate the biosynthesis of Ag NPs using plant extract of Melissa officinalis (at the eight leaf stage) grown under in vitro (controlled) condition for the first time.Materials and Methods: Biosynthesis of Ag NPs using plant extract was carried out and formation of Ag NPs confirmed by UV-Visible spectroscopy, X-ray diffraction (XRD), Field Emission Scanning Electron Microscope...

The formation of triangular-shaped adatom islands and vacancy islands on Ag(111) at room temperature is observed in a local growth experiment. The tip of a scanning tunneling microscope (STM) vibrating normal to the surface leads to a local modification. Atoms are removed from flat terraces and renucleate as adatom islands. Simultaneously with the modification process the surface is imaged with...

In this paper, algebraic-geometric (AG) codes associated with the GGS maximal curve are investigated. The Weierstrass semigroup at all Fq2-rational points of the curve is determined; the Feng-Rao designed minimum distance is computed for infinite families of such codes, as well as the automorphism group. As a result, some linear codes with better relative parameters with respect to one-point He...

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...

Heterostructured nanocrystals containing multiple components are attracting attention due to not only their multifunctional properties but also new features arising from the effective coupling of different domains.1,2 Numerous semiconducting heterostructures have been synthesized by gas-phase deposition and are being used for the miniaturization of electronic and photonic circuits.3 Metallic he...
