[ 1 ] - Encapsulation of Methane Molecules into C60 Fullerene Nanocage: DFT and DTFB-MD Simulations
Extensive urbanization has greatly raised the demand for cleaner coal- and petroleum-derived fuels. Mainly composed of methane, natural gas represents a promising alternative for this purpose, making its storage a significant topic. In the present research, deposition of methane molecules in C60 fullerene was investigated through a combined approach wherein density functional based tight bindin...
[ 2 ] - Functionalization of multi-wall carbon nanotubes with Metformin derivatives and study of their antibacterial activities against E-Coli and S. aureus
Bacteria can grow in different materials that are in close contact with humans, foods, etc., so, it is very important to control this matter in order to prevent risk of infections. Antimicrobial resistance (AMR) threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi. Multiwall carbon nanotubes (MWNTs) have inte...
[ 3 ] - Magnetic and microwave absorption properties of barium hexaferrite doped with La3+ and Gd3+
In this paper, BaLaxGdxFe12-2xO19 (x=0.2, 0.4, 0.6 and 0.8) were synthesized via sol-gel auto-combustion method. Fourier transform infrared spectroscopy (FTIR) of samples was represented that the bands at 400 and 500 cm-1 were related to the formation of hexaferrite phase. The (x-ray diffraction) XRD patterns were matched exactly with the structure of barium hexaferrite. (Field emission scanni...
[ 4 ] - A New Method for the Synthesis of New Derivatives of “1,3- diaryl-2-n-azaphenalene and n-acyl-1,3-diaryl-2-N-azephenylene” by Using Nano catalyst and Analyzing Antibacterial Activity of Structures
In this research, synthesized well derivatives of 1,3-diaryl-2-N-azaphenalene and N-acyl-1.3-diaryl-2-N- azaphenalene as a macromolecule in the presence of nanoparticles (Fe3O4 coated with L-Arginine)as a magnetic Nano catalyst in a one-pot reaction of compounds 7.2-Naphthalene diol, aldehydes,ammonium derivatives (ammonium acetate or ammonium hydro phosphates) and solvent (wa...
[ 5 ] - Effect of SiO2 nanoparticles on phytochemical and anatomical alterations in Anthemis gilanica
In this research, effects of SiO2 nanoparticles (NPs) on the growth, antioxidant properties, and phenolic and flavonoid contents were investigated in Anthemis gilanica plants from the Asteraceae family. Following seed germination, seedlings were cultured under Hoagland growth media and were treated with different concentrations of SiO2NPs (0, 2, 4, 6 and 8 g L-1). The results showed that SiO2 N...
[ 6 ] - Comparative evaluation of different extraction methods for the assay of phytochemicals and antioxidant activity of Valeriana officinalis roots
Background & Aim:Medicinal plants are rich sources of substances with nutraceutical and health benefits. Valeriana officinalis L. (Valerianaceae) is a known medicinal plant used in traditional medicine throughout the world. The present study aimed to evaluate the efficiencies of three methods for antioxidant extraction from Valeriana officinalis</...
[ 7 ] - Adenine molecule interacting with golden nanocluster: A dispersion corrected DFT study
The interaction between nanoparticles and biomolecules such as protein andDNA is one of the major instructions of nanobiotechnology research. In this study,we have explored the interaction of adenine nucleic base with a representativegolden cluster (Au13) by using dispersion corrected density functional theory(DFT-D3) within GGA-PBE model of theory. Various active sites ...
[ 8 ] - Effects of magnetic fields on some physiological factors and antioxidant capacity of Silibum marianum L. seedlings under salt stress
Salinity is one of the most important abiotic stresses that have restricted affects on plant growth and yield. Magnetic field can ameliorate the negative effect of salinity with induction of plant antioxidant activity. In present research, the effect of static magnetic fields (0 anf 4 mT) on some physiological parameters and antioxidative capacity were investigated under salinity stress at conc...
