A chemical graph is a graph that is produced from some molecular structure by applying some graphical operations. The demonstration of chemical compounds and chemical networks with the M-polynomials is a revolution and the M-polynomial of different molecular structures contributes to evaluating many topological indices. In this paper we worked out M-Polynomial and topological indices of the tadpole graph, then we recovered numerous topological indices using the M-polynomials.https://www.echemcom.com/article_126645_2dd1898cb2f33cd29e32ca87f1d040e5.pdfSami Publishing Company (SPC)Eurasian Chemical Communications2717-05353320210301Nanocarbon-assisted biosensor for diagnosis of exhaled biomarkers of lung cancer: DFT approach15416112693210.22034/ecc.2021.269256.1126ENMahmoud MirzaeiBiosensor Research Center, School of Advanced Technologies in Medicine, Isfahan University of Medical Sciences, Isfahan, Iran0000-0001-9346-4901Oguz GulserenDepartment of Physics, Bilkent University, Ankara, TurkeyMohammad RafieniaBiosensor Research Center, School of Advanced Technologies in Medicine, Isfahan University of Medical Sciences, Isfahan, IranAmirhossein ZareIsfahan Pharmacy Students’ Research Committee, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IranJournal Article20210118Density functional theory (DFT) calculations were performed to investigate a nanocarbon-assisted biosensor for diagnosis of exhaled biomarkers of lung cancer. To this aim, an oxidized model of C<sub>20</sub> fullerene (OC) was chosen as the surface for adsorbing each of five remarkable volatile organic compounds (VOC) biomarkers including hydrogen cyanide, methanol, methyl cyanide, isoprene, and 1-propanol designated by B1-B5. Geometries of the models were first optimized to achieve the minimum energy structures to be involved in further optimization of B@OC bi-molecular complexes. The relaxation of B counterparts at the surface of OC provided insightful information for capability of the investigated system for possible diagnosis of such biomarkers. In this case, B1 was placed at the highest rank of adsorption to make the strongest B1@OC complex among others whereas the weakest complex was seen for B4@OC complex. The achievement was very much important for differential detection of each of VOC biomarkers by the investigated OC nanocarbon. Moreover, the recorded infrared spectra indicated that the complexes could be very well recognized in complex forms and also among other complexes. As a final remark, such proposed nanocarbon-assisted biosensor could work for diagnosis of remarkable VOC biomarkers of lung cancer.https://www.echemcom.com/article_126932_68a9da08afff1a39d6069f4e4996ace5.pdfSami Publishing Company (SPC)Eurasian Chemical Communications2717-05353320210301Understanding the internal marketing orientation and its consequences in small finance bank: A case study analysis16216912694210.22034/ecc.2021.270510.1130ENLakshmi Prasad PadhyResearch Scholar, School of Management, KIIT Deemed to be University (Institute of Eminence) Bhubaneswar, IndiaIpseeta SatpathySchool of Management, KIIT Deemed to be University (Institute of Eminence) Bhubaneswar, India0000-0002-0155-5548B.C.M.

M-polynomial is also an algebraic polynomial that is used to find the expressions of several degree dependent topological indices. These topological indices have the ability to explore the information store in the chemical molecule. In this work, we computed the M-polynomial and then obtained the degree-based topological indices for the benzene ring embedded in P-type-surface in 2D network. We also explored the results graphically.https://www.echemcom.com/article_127570_e79369c870f0b39b78d6c21c45885001.pdfSami Publishing Company (SPC)Eurasian Chemical Communications2717-05353320210301Conductance and solvent behaviour of 6-(4-chlorophenyl)-1, 2, 3, 4-tetrahydro-2, 4-dioxopyrimidine-5-carbonitrile in 60% DMSO at different temperatures18719212790310.22034/ecc.2021.267155.1119ENManoj RameshGawareDepartment of Chemistry, M.

Research on fig leaves growing in Mardakan and Nardaran areas of Absheron has been carried out on EPR spectrometer. Studies have shown that stressors cause the formation of nanophase particles of biogenic origin in living systems. These nanoparticles lead to the formation of magnetic properties in biological systems and the formation of the broad EPR signal that we first discovered in plants. It was found that the magnetic properties depend on the type of plant and the environmental conditions in which they live and the characteristics of EPR signals characterizing magnetic nanoparticles (amplitude, signal width, g factor, etc.) are strongly dependent on temperature and that this signal has magnetic anisotropy. Studies of fig leaves have shown that as a result of biomineralization under stress, they form magnetic nanoparticles of iron oxide. In addition, the high intensity of the broad EPR signal characteristic of nanophase magnetic particles detected in fig leaves growing in Mardakan area (Azerbaijan) indicates that the plant system in this area is more exposed to pollutants and the area is more environmentally polluted than Nardaran Area (Azerbaijan). The characteristic verve phase transition occurs at a temperature of 120-125 K in the behavior of parameters such as the amplitude of the magnetic resonance signal and the width of the magnetic resonance line. The results were confirmed by the messabauer method.https://www.echemcom.com/article_128058_97bd04fcb4604f9e56d930fba218f803.pdfSami Publishing Company (SPC)Eurasian Chemical Communications2717-05353320210301Characterization of chemical structure of water-soluble polysaccharides from Sudanese Ziziphus spina Christi fruits20020912805910.22034/ecc.2021.273357.1139ENMohamed AamerAbubakerCollege of Life Science, Northwest Normal University, Lanzhou 730070, ChinaDepartment of Biology, Faculty of Education, University of Khartoum, Khartoum, 11111, Sudanhttps://orcid.org/00Hamouda AdamHamoudaCollege of Chemistry and Chemical Engineering, Northwest Normal University, Lanzhou, 730070, ChinaLele ChenCollege of Life Science, Northwest Normal University, Lanzhou 730070, ChinaLing DingCollege of Life Science, Northwest Normal University, Lanzhou 730070, ChinaSheng Yong ZhuCollege of Life Science, Northwest Normal University, Lanzhou 730070, ChinaJi ZhangCollege of Life Science, Northwest Normal University, Lanzhou 730070, China0000-0003-2773-5245Liang Wan FuCollege of Life Science, Northwest Normal University, Lanzhou 730070, ChinaJournal Article20210222Polysaccharides have multiple significant roles and possess extensive bioactivities in field of medicine, healthcare, food and cosmetic industries, because of their therapeutic effects and relatively minimal toxicity. For the first time, we investigated the chemical structure of <em>Ziziphus spina Christ</em> fruits polysaccharides fraction. The plant is classified as one of the most important Sudanese medical plant, still not adequately researched.<br /> The <em>Z. spina Christi </em>polysaccharides fraction was extracted by using cold water extraction method, deproteinized via Savage’s method, then after participated by using ethanol 80%, the precipitant fractions were dried via lyophilized for 24h. ZSCFPs was investigated by using colorimetric and analytic methods; the colorimetric assays were carried out to determine some functional groups in the polysaccharides fraction such as phenol-sulfuric acid, sulfuric acid - carbazole reaction, ferric chloride reaction. The analytical assays were carried out to confirm the chemical structure of the ZSCFP 80%, which were FTIR spectra, Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and X-ray diffraction (XRD).https://www.echemcom.com/article_128059_6b3c02cd5d068adee48bd5f239102ddd.pdf
