Heterogeneous Ziegler-Natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. In our previous study, it was reported that MgCl2-supported titanocenecatalysts can generate both Ziegler-Natta-type and metallocene-type active sites according to the type of activators.The dual active site nature of the supported titanocene catalysts was furt...

Preparing sustainable and highly efficient biomass-based carbon materials (BBPM) as adsorbents remains a challenge for organic pollutant management. In this work, novel biobased material has been synthesized via facile, sustainable, different single-step pyrolysis chemical methods (KOH, ZnCl2, ZnSO4, MgCl2) using Norway spruce bark suitable precursor. The effects of each activator on the physic...

So-called specific ion effects strongly impact physicochemical phenomena in among others, morphologies of polymeric membranes. This can be correlated to the identity ions, rather than just their charge or concentration. We use this effect tune properties layer-by-layer membranes prepared with polyelectrolytes polydiallyldimethylammonium chloride and polystyrene sodium sulfonate. To systematical...

In the present work, we have concentrated on structural, electronic, and optical properties of single-layer phase MgCl2. When bulk MgCl2 reduces to monolayer form, then it exhibited indirect direct bandgap transformation. The result indicates that exhibits insulating characteristics with a 7.377 eV whereas its form has an 7.02 eV. It means when reducing dimensionally materials than significantl...

Molten chloride salt is recognized as a promising heat transfer and storage medium in concentrating solar power recent years, but there serious lack for thermal property data of molten salts. In this work, local structures properties salt—including NaCl, MgCl2, ZnCl2—were precisely simulated by Born–Mayer–Huggins (BMH) potential rigid ion model (RIM) polarizable (PIM). Compared with experimenta...

ECM protein enrichment and immunoblotting 100mg of frozen samples were homogenized using a polytron (Kinematica, Bohemia, NY) in 250μL of buffer C (HEPES pH7.9, MgCl2, KCl, EDTA, Sucrose, Glycerol, Sodium OrthoVanadate) of the CNMCS protein extraction kit. Lysates were then spun for 20 min. at 15,000 rpm at 4°C, the supernatant was saved (intermediate fraction 1, enriched for cytosolic proteins...

We have examined binding of the CREB B-ZIP protein domain to double-stranded DNA containing a consensus CRE sequence (5'-TGACGTCA-3'), the related PAR, C/EBP and AP-1 sequences and the unrelated SP1 sequence. DNA binding was assayed in the presence or absence of MgCl2 and/or KCl using two methods: circular dichroism (CD) spectroscopy and electrophoretic mobility shift assay (EMSA). The CD assay...
