نویسنده
چکیده
Ordered La3A ln Structure, Stannide The title compound has been obtained by arc-melting of the elemental components and subsequent annealing at 800 °C. It crystallizes in the orthorhombic space group Immm, a = 430.3(1), b = 1235.0(2), c = 967.6(3) pm, V 0.5142(2) nm3, Z = 2. The structure has been determined from single-crystal X-ray data and refined to R = 0.0181 for 747 F2 values and 28 variables. It is of a new type and can be described as a ternary ordered version of the binary La3A lu -type structure. Dy3Co6Sn5 is built up from DyCo2Sn2 and DyCo2Sn slabs with ThCr2Si2 and Cu3Au-like atomic arrangements, respectively. Its crystal chemistry is com pared with that of structurally related rare earth transition metal gallides.

La5Zn2Sn
A single crystal of penta-lanthanum dizinc stannide, La(5)Zn(2)Sn, was obtained from the elements in a resistance furnace. It belongs to the Mo(5)SiB(2) structure type, which is a ternary ordered variant of the Cr(5)B(3) structure type. The space is filled by bicapped tetra-gonal anti-prisms from lanthanum atoms around tin atoms sharing their vertices. Zinc atoms fill voids between these bicapp...
متن کاملA study on the catalytic activity of a new acidic ordered mesoporous silica (SBA-15)
SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as a catalyst. This mesoporous silica due to silanol groups is easily functionalized by various organic materials. A new acidic ordered functionalized mesoporous silica (SBA-15-Aminopropyl-Benzyl-SO3H) has been introduced as an efficient catalyst for ...

متن کاملConvex structures via convex $L$-subgroups of an $L$-ordered group
In this paper, we first characterize the convex $L$-subgroup of an $L$-ordered group by means of fourkinds of cut sets of an $L$-subset. Then we consider the homomorphic preimages and the product of convex $L$-subgroups.After that, we introduce an $L$-convex structure constructed by convex $L$-subgroups.Furthermore, the notion of the degree to which an $L$-subset of an $L$-ord...
متن کاملIntroducing New Structures for D-Type Latch and Flip-Flop in Quantum-Dot Cellular Automata Technology and its Use in Phase-Frequency Detector, Frequency Divider and Counter Circuits
Quantum-dot cellular automata (QCA) technology is an alternative to overcoming the constraints of CMOS technology. In this paper, a new structure for D-type latch is presented in QCA technology with set and reset terminals. The proposed structure, despite having the set and reset terminals, has only 35 quantum cells, a delay equal to half a cycle of clocks and an occupied area of 39204 nm2. T...
