The effective compressive elastic modulus of the cellular rhombic dodecahedron structure, with m × n cells in X- and Y- directions matrix, has been studied. structure without border constraint is a function n; while for constraints it found unique that independent n, porosity structure. In order to study understand range explicit expression parameters, an analytical model developed evaluate low...

Academic insignia of the Faculty Chemical Technology UCT Prague have a history and are used in academic ceremonies (graduation, ceremonial scientific councils, awarding honorary doctorates, etc.). Insignia consists single chain with medal scepter. They made gold-plated silver decorated natural synthetic precious stones. The central motif head sceptre is pentagonal dodecahedron cut from sulphide...

Intensive systemic chemotherapy is the gold standard of acute myeloid leukemia (AML) treatment and associated with considerable off-target toxicities. Safer targeted delivery systems are thus urgently needed. In this study, we evaluated a virus-like particle derived from human type 3 adenovirus, called adenoviral dodecahedron (Dd) to target AML cells. The vectorization leukemic cells was proved...

The Co3O4 hollow dodecahedron (Co3O4@CN) was prepared by calcining ZIF-67 in N2 and then air atmosphere. In the Co3O4@CN compound material, nanoparticles (Co3O4 NPs) are anchored carbon skeleton, solving aggregation problem of NPs. Because retains porous structure ZIF-67, presence Co2+ Co3+ favors electron transfer between enzyme substrates, it has excellent peroxidase-like (POD-like) activity....
