Discrete homo Cu-Cu-Cu and hetero Cu-Pd-Cu or Cu-Co-Cu metal arrays are prepared within an organic-pillared coordination box by inserting M(ii)-azaporphine/porphine cartridges (M = Cu(ii), Pd(ii) or Co(ii)), where the metal arrays show unique spin interactions in ESR: in particular, Deltam(s) = 3 for the Cu-Cu-Cu array.

Phytoremediation consists of taking advantage the capacity certain plants to absorb, accumulate, or metabolize contaminants. In this study, Eichornia crassipes (water lily) treated with water (WLW) and NaOH (WLN) was investigated as an adsorbent for removal Ni(II) Cu(II) present in aqueous solution, focusing on determining most efficient conditions (adsorbent concentration, contact time, pretre...

Amyotrophic lateral sclerosis has been linked to the gain of aberrant function of superoxide dismutase, Cu,Zn-SOD1 upon protein misfolding. The mechanism of SOD1 misfolding is thought to involve mutations leading to the loss of Zn, followed by protein unfolding and aggregation. We show that the removal of Zn from SOD1 may not lead to an immediate unfolding but immediately deactivates the enzyme...

Zinc and Cu metabolism in crustacea changes dramatically during the molt cycle. Metallothionein (MT) and MT-like proteins are implicated in the handling of both metal ions as well as in the detoxification of Cd. Distribution of Cd2 / Cu / and Zn2 / in cytosol and among MT-like species has been determined. Lobsters were treated to induce MT as in mammals with dexamethasone (dex) or stress from t...

Raw and waste wool were studied for the removal of heavy metal ions such as Zn(II) Cu (II) from wastewater. Characterization both samples was done by attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), zeta potential analysis. The sorption kinetics on also studied, compared with different models adsorption isotherms. maximum ef...

Direct air capture is regarded as a plausible alternate approach that, if economically practical, can mitigate the increasing carbon dioxide emissions associated with two of the main carbon polluting sources, namely stationary power plants and transportation. Here we show that metal-organic framework crystal chemistry permits the construction of an isostructural metal-organic framework (SIFSIX-...

in order to study the cu(ii) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of pvc powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. the sensor showed a near nernstian response for cu(ii) ions over a concentration range from 1.0×0-6 –1.0×0-2 m with a slope of 28.90.5 mv per concentration decade with a working ph range of 3.5-6.3. ...
