Fast-ion conduction in an unusual three-dimensional coordination polymer containing nano-sized channels

Sonochemical Synthesis of Novel Nano Flower Lead(II) Metal-organic Coordination Polymer: A New Precursor to Produce Nano-sized PbO

Metal-organic coordination polymers are a class of organic–inorganic materials consists of metal ions linked together through multi-dentate organic ligands, to form a polymeric chain. These materials have received a great deal of attention in a wide range of different areassuch as catalysis, sensing, luminescence, separation and storage used . The new nano flowerPb(II) 1Dmetal-organic chain {[P...

Focused Ion Beam Based Three-Dimensional Nano-Machining

In recent days, the micro/nano machining becomes an important process to fabricate micro/nano scale dimensional patterns or devices for many applications, especially in electrical and electronic devices. There are two kinds micro-machining in use. i) bulk micromachining, ii) surface micro-maching. In the case of bulk micromaching, the structures can be made by etching inside a substrate selecti...

Ion conduction and selectivity in K(+) channels.

Potassium (K(+)) channels are tetrameric membrane-spanning proteins that provide a selective pore for the conductance of K(+) across the cell membranes. These channels are most remarkable in their ability to discriminate K(+) from Na(+) by more than a thousandfold and conduct at a throughput rate near diffusion limit. The recent progress in the structural characterization of K(+) channel provid...

Ion Conduction and Selectivity in K+ Channels

Thermal- and photoinduced spin-state switching in an unprecedented three-dimensional bimetallic coordination polymer.

The compound {Fe(pmd)[Ag(CN)2][Ag2(CN)3]} (pmd=pyrimidine) was synthesized and characterized. Magnetic, calorimetric and single crystal visible spectroscopic studies demonstrate the occurrence of a two-step high-spin (HS) right arrow over left arrow low-spin (LS) transition. The critical temperatures are T(c1)=185 and T(c2)=148 K. Each step involves approximately 50 % of the iron centers, with ...
