Background: Surface properties of a biomaterial could be critical in determining biomaterial’s biocompatibility due to the fact that the first interactions between the biological environment and artificial materials are most likely occurred at material’s surface. In this study, the surface properties of a new nanocomposite (NC) polymeric material were modified by combining plasma treatment and...

background: the present study aimed to investigate the nailfold capillaroscopy (nc) features of the patients with dermatomyositis (dm) and its correlation with their disease activity indices, physical findings, and laboratory results. methods: the present cross-sectional study was conducted on 27 dm patients above 16 years old who had referred to an(there are 3 clinics not one) outpatient rheum...

The complex [(PhCH2NC)AuCl], 1, was prepared by the reaction of [(Me2S)AuCl], A, with an equimolar amount of benzyl isocyanide (PhCH2NC) ligand. Through a salt metathesis reaction, the chloride ligand in 1 was replaced by potassium benzothiazole-2-thiolate (Kbt) and potassium benzoimidazole-2-thiolate (Kbi) to a...

Ionic liquids (ILs) have the advantages of low cost, eco-friendliness, abundant heteroatoms, excellent solubility, and coordinated ability with metal ions. These features make ILs a suitable precursor for fabricating single-atom catalysts (SACs). Herein, we prepared various single atoms anchored on ultrathin N-doped nanosheets (denoted as Cu1/NC, Fe1/NC, Co1/NC, Ni1/NC, Pd1/NC) by direct pyroly...

The application of nanoparticles in order to enhance the composites properties has been recently attracted many researchers' attentions. To increase the mechanical and physical properties of the composites, the nanoparticles have no significant effect on the weight and nanostructure of composites. One of the well-known nanoparticles is the Nanoclay (NC) that have been widely used in industries ...

electrospinning was applied to nitrocellulose (nc) solutions  in dmf, dmso  and  ethyl  methyl  keton  to  obtain  nc  nanofibers. electrospraying  process  was  observed  when  dmf  was  used  as solvent.  in  comparison  to nc/dmf, nc/dmso  solution  resulted  in the  formation  of  a  coating  film  as  indicate  by  sem.  two  different electrospun  nanofibers,  smooth  nanofibers  with  90...
