Cadmium oxide (CdO) nanoparticles were prepared by using sodium dodecyl sulfate (SDS), Cd(OAc)2.2H2O and sodium hydroxide as starting materials. The sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). The XRD pattern proves that the final product has cubic phase and the particle size diameter of the nanoparticles are 36.4 nm. The SEM was used for direct visualization of the size and shape of the nanoparticles. The morphology of the CdO was found nanospherical. Antibiotics are a major class of drugs included in the designation of emerging contaminants, representing a high risk to natural ecosystems. We studied the degradation of Sulfathiazole antibiotic by nanosized CdO under ultraviolet irradiation. Various experimental parameters such as initial Sulfathiazole (STZ) concentrations, initial CdO concentration and initial pH were investigated. According to the results this method can be good performance in removal of Sulfathiazole.","PeriodicalId":14081,"journal":{"name":"international journal of nano dimension","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79991965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nano Dimens., 2017; 8(2): 107-113., DOI: 10.22034/ijnd.2017.24833 Abstract In this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (LDDS-CNTFET) with a negative differential resistance (NDR) characteristic, called negative differential resistance LDDS-CNTFET (NDR-LDDS-CNTFET). The device was simulated by using a non equilibrium Green’s function method. To achieve this phenomenon, we have created two quantum wells in the intrinsic channel by using two n-type regions. In the wells that are separated by a thin barrier, two resonance states are generated. On the other hand, the thickness of the barrier between the source and the well is variable depending on the energy level. Accordingly, with increasing gate-source voltage, the number of tunneling electrons and consequently drain-source current are varied. Furthermore, we have presented a structure with two n-type and three p-type regions in the channel that illustrates a larger NDR region. In this structure, the peak and valley of the drain-source current are shifted when compared with the previous structure. Finally, we investigated the effect of doping concentration on the NDR parameter.","PeriodicalId":14081,"journal":{"name":"international journal of nano dimension","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74084709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural, spectroscopic and electronic properties like optimized geometries, HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energy levels, binding energy, adsorption energy, vibrational frequency and density of states (DOSs) of the pure Cun nanoclusters, and CunCO complexes in their ground state were thoroughly analyzed. The CO adsorbed on the Cun nanoclusters showed a stretch frequency at 1950-2052 cm-1, which was red-shifted relative to that of gas-phase CO (2143 cm-1). This red-shift was believed to arise from the charge transfer from the Cu metal d states to the CO antibonding 2π* level. The CO adsorption on the Cu nanoclusters was chemisorption in nature with the Cu–C bond length (adsorption height) in the range of 1.85-1.92 Å.","PeriodicalId":14081,"journal":{"name":"international journal of nano dimension","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86907762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nano Dimens., 2017; 8(2): 124-131., DOI: 10.22034/ijnd.2017.24878 Abstract Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been evaluated to investigate the structural and electronic properties of the models. The structural configurations of tautomers show different relaxations at the C60 surface yielding different magnitudes of total and binding energies. Moreover, deformation of each tautomer due to relaxation at the C60 surface with respect to the initial singular structure has been examined. Complimentary parameters of energy gaps and dipole moments exhibit the effects of relaxations at the C60 surface for the MPO counterparts. Atomic scale CQ properties also indicate that the electronic properties of atoms show significant changes for tautomers and hybrid systems. As a final note, the tautomeric structures in singular and hybrid forms exhibit different electronic properties because of effects of interactions with C60, especially for the interaction regions.","PeriodicalId":14081,"journal":{"name":"international journal of nano dimension","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74708681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
