Results and Discussion 2.1 Chemistry Recently, the Cu(I)-mediated cycloisomerization of alkynyl pyridines become growing interest in the synthesis of indolizine derivatives.
With the aim to obtain potentially anti-inflammatory indolizine and study their structure-activity relationship (SAR), a series of 3-aryloxylindolizine were synthesized through the Sonogashira coupling/5-endo-trig cycloisomerization domino strategy (Scheme 1).
The future studies on the structure-activity relationship of the indolizine derivatives and their anti-inflammatory activity were under way in our research group.

The basic explorations of structure property correlations and the variety of commercial and biological applications all attest to the fact that copolymerisation is highly useful [5].
The structure of synthesized copolymer was confirmed by FT-IR technique.

On the other hand, Flucto-CMP applies electromagnetic waves that result in BTA forming a much softer and less dense Cu(II) structure (Figure 2) which causes high removal rates at less mechanically-aggressive conditions.
Figure 2: Dense and rugged passivation layer formed during conventional Cu CMP (top), and softer and less dense Cu(II) structure during Cu polishing with Flucto-CMP® (bottom).
For example, polishing SiC involves the use of aggressive redox chemistries (i.e., KMnO4) and harsh polishing conditions such as high nanoparticle loading and shear force), which lead to an increase in removal but have the potential to increase surface defects.
Exploiting the synergistic relationship between the slurry additive and an H2O2-based formulation has shown that SiC removal is highly dependent on the formation of a modified surface complexation layer produced by the interaction of the substrate with the slurry additives, creating an electrophilic chemistry-nanoparticle macroenvironment.

One of the most important properties of the anionic clays is their high anionic exchange capacity that is related to their lamellae structure, this allows the exchange of their original anions with those present in an aqueous solution [4-7].
ZADX prepared by using 0.1 M 3,4D produced sharp, symmetrical with high intensity peaks especially for the 003 reflection with basal spacing of 19.0 Å can be clearly observed indicates that pure phased nanolayered structure was obtained.

Improved detection of Hg2+ in aqueous solution with high sensitivity and selectivity by using mercury-specific DNA, Sybr Green I and gold nanoparticles Hui Xu1,a *, Shuli Gao1,b, Jiannong Chen2,c and Quanwen Liu1,d 1School of Chemistry and Material Sciences, Ludong University, Yantai 264025, China 2Department of Physics, Ludong University, Yantai 264025, China a xuhui235@yahoo.com.cn, b shuli0049@126.com, c jnchen1963@yahoo.com.cn, d ldu_lqw@163.com Keywords: Sybr Green I; Hg2+; K+; Gold nanoparticle Abstract.
Four protocols have been reported for detection of Hg2+ using a mercury specific DNA (MSD) based on T-Hg2+-T (T=thymine) chemistry because T-T mismatch shows high selectivity to Hg2+ against many other metal ions [33].
It forms a hairpin structure in the presence of Hg2+, and presents a random coil form in the absence of Hg2+.
K+ led to significant fluorescence increase which suggested that the PSO folded into G-quartet structure and being intercalated by SG.
