The British Society of Thoracic Imaging (BSTI) have built a free to use,anonymised and encrypted online portalto upload and refer imaging of patients with either confirmed or suspected COVID-19. CIFAR Action on COVID-19 SDOs International Activity ...
structure. To this For single IS- or HS-Co3+ ions embedded in the background of LS-Co3+ ions in the unit cell, we have six inequivalent spin-structures. Table 3 shows the typical energies calculated at U = 8 eV. It is found that the energies Scientific Reports | 6:...
[37] prepared a high-density corn-like Co3O4/graphene hybrid material by direct pyrolysis of Co(NO3)2·6H2O on graphene NS through self-assembly induced by graphene wrinkles. This composite preserved a high reversible capacity of 1060 mA h g−1 after 50 cycles at a current ...
On the other hand, the electron-rich dπ orbitals of a FePc sheet not only contain the spin-up orbitals of HOMO-2 and HOMO-3, but also the HOMOs with spin-down. Additionally, contrary to the high-lying dz2 orbital of a CrPc sheet, the electron-deficient dz2 orbital of the FePc ...
3. Results and discussion 3.1. Preparation and characterization of MNPs and mMNPs The synthesis process for MMDS preparation is shown in Fig. 2A. The MNPs were obtained by the reaction of FeCl36H2O, MgCl26H2O and sodium acetate trihydrate in thermos-solvent (180 °C), and were further modif...
The dielectric properties, optical properties and thermophysical properties were measured for the SrM keeping Fe3+/Sr2+ ratio 10 calcined at 1000 °C. The synthesized SrM can be applied in magnetic recording media and as photocatalyst due to its low coercivity (2764.48 Oe), high saturation ...
Currently, water oxidation electrocatalysts consist of noble-metal oxides, such as IrO2 and RuO2, because of their high stability in acid, small overpotential, and low Tafel value.2,3 However, the application of precious-metal-based catalysts on an industrial scale is cost prohibitive. To make...
The high voltage, feeding rate, and distance between the cathode and the anode were fixed at 13 kV, 0.05 mm min−1 and 15 cm, respectively, for the electrospinning. 2.1.3 Synthesis of CdS@PAN@CoCu-ZIF nanofibers 0.582 g of Co(NO3)2·6H2O and 0.097 g of Cu(NO3)...
