This article presents a strategy for the fabrication of ordered microstructures using concepts of design inspired by molecular self-assembly and template-directed synthesis. The self-assembling components are 4-μm-thick hexagonal metal plates having sides 10 μm in length (“hexagons”), and each template consists of a 4-μm-thick circular metal plate surrounding a central cavity, the perimeter of ...

Chemists have been fascinated for a long time with phenomenon of bimolecular spectroscopy and dynamics of Nano–sized molecules and clusters as cross–linking–induced anti–cancer and Immune-Oncology (I-O) Nano drugs delivery in DNA/RNA of human cancer cells’ membranes under synchrotron radiations [1–25]. This concept generally associated with anti– cancer and Immune-Oncology (I-O) Nano drugs deli...

CuO nano particles were obtained by calcination of nano-sized  [Cu(C4H4O4)(bipy)(H2O)2].2H2O (1) and [Cu(2‚2′-bipy)](C4H4O4)0.5(NO3)(H2O) (2) which are two  Cu(II) coordination polymers. The two coordination polymers [Cu(C4H4O4)(bipy)(H2O)2].2H2O and [Cu(2‚2′-bipy)](C4H4O4)0.5(NO3)(H2O) were synthesized and characterized by Fourier transform infrared spectra (FT-IR spectroscopy), thermal gravim...

Urchin-like NiCo2S4 sub-micron spheres integrated with nano-sized and micro-sized structures, which were synthesized via a facile one-pot method, deliver efficient electrocatalytic activities for oxygen reduction and evolution reactions. The excellent electrocatalytic property of NiCo2S4 sub-micron spheres is originated from their unique urchin-like microstructure, composition and d-electronic ...

nano sulfated titania was tested as solid acid heterogeneous catalyst for the synthesis of 4-(trifluoromethyl) coumarin and coumarin derivatives under solvent-free condition. factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents.  this nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. the prepared sulfated titania s...
