The heavy lanthanide selenides AgLnSe2 (Ln=Ho–Yb) crystallize in the orthorhombic AgErSe2 type structure (P212121). The lanthanide ions are placed in the centres of slightly distorted octahedra, whereas each of the silver ions is surrounded by four

Experimental results of an oscillatory reaction of the Belousov-Zhabotinsky type in the system Mn 2+ -KBrO 3 -H 2 SO 4 ― citric acid are depicted. The transition from the steady state to oscillations occurs through the so-called saddle-node infinit
