Design and synthesis of new symmetrical Schiff bases
A series of symmetric multidentate Schiff base ligands 1–13 based on the N‚N′-4‚4′-ethylenebiphenylbis-3-methoxysalicylideneimine for used to bind various transition metals detection of K, AgI‚ CuII, Sr II Co II and NiII at trace levels in real-world samples has been synthesized purified and their structures was characterized.
متن کاملA new tractable combinatorial decomposition
This paper introduces the umodules, a generalisation of the notion of module in graph theory. The structure to be decomposed, so-called homogeneous relation, captures among other undirected graphs, tournaments, digraphs, and 2−structures. Our resulting decomposition scheme when restricted to undirected graphs generalises the well-studied modular graph decomposition, and meets the recently intro...
متن کاملA New Single-phase Symmetrical Cascade Multilevel Inverter with Low Number of Power Switches
In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...
متن کاملDesigning new symmetrical facial oligothiophene amphiphiles.
In this study we designed a new class of symmetrical facial oligothiophene amphiphiles, which could be obtained in fewer steps than for previously reported analogues, but still possess the specific substituent sequence to control their backbone curvature. This novel design allows the late-stage introduction of hydrophilic groups, aiding both purification and ease of structure variation. Followi...
متن کاملA New Linguistic Modelling of the Symmetrical Threshold Semantics
In this contribution a new matching function for a symmetrical threshold semantics is presented. It can be interpreted as a tuning of that proposed in [10] which was defined using an ordinal fuzzy linguistic approach. This new matching function is defined using a 2-tuple fuzzy linguistic approach and, consequently, avoids the loss of precision and information in final results. On the other hand...
