  Montmorillonite(MMT)/CdS nanocomposites can be obtained using simple ionic exchange between Na(I)-MMT and Cd[SC(NH2)2]42+∙2NO3. The resulting products may be annealed to give (MMT)/CdS nanocomposites as it was proved by XRD analysis.

  - Scientific Reports - Year 2023

  We have successfully synthesized three osmium-based hexagonal Laves compounds ROs2 (R = Sc, Y, Lu), and discussed their physical properties. LeBail refinement of pXRD data confirms that all compounds crystallize in the hexagonal centrosymmetric MgZn2- type structure (P63/mmc, No. 194). The refined lattice parameters are a = b = 5.1791(1) Å and c = 8.4841(2) Å for ScOs2, a = b = 5.2571(3) Å and c = 8.6613(2) Å for LuOs2 and a =...

• A Canonical Switched Capacitor DC-DC Converter. A look at how the historical SC synthesis problem is getting solved

  Publication

  • M. Makowski

  - Year 2014

  We reconsider a solution to the historical problem in switched capacitor (SC) DC-DC converter synthesis. Specifically, we retackle the problem of constructing an SC twophase network realizing arbitrary voltage conversion ratio within rational bounds defined. Theoretical foundations are available in our earlier research [3] where a nonconstructive proof of existence was given. We briefly review and comment on known circuit solutions...

  - PHYSICAL REVIEW B - Year 2016

  Polycrystalline samples of four intermetallic compounds: MV2Al20 (M=Sc, Y, La, and Lu) were synthesized using an arc-melting technique. The crystal structures were analyzed by means of powder x-ray diffraction and Rietveld analysis, and the physical properties were studied by means of heat capacity, electrical resistivity, and magnetic susceptibility measurements down to 0.4 K. For ScV2Al20, LuV2Al20, and YV2Al20, superconductivity...
