Osmotic energy, as a sustainable energy source with little environmental impact, has drawn much attention in both academia and industry in recent years. Osmotically driven membrane processes can harvest the osmotic energy and thus have great potential to produce sustainable clean water or electric energy. The draw solution, as an osmotic component, has been more and more explored by scientists ...

Cold In-place Recycling (CIR) has been widely used in the world since it is easy to apply field at a low cost. However, not normally as surface layer result of its inconsistent quality due an excessive amount fine aggregates pulverized during milling process. Hot (HIR) can retain original shape aggregates, but often produces large Volatile Organic Compounds (VOCs). Therefore, third in-place rec...

Biochar-based carbonaceous adsorbents are gaining interest due to their high availability, ease of modification, and low cost; however, they show limited adsorption CO2 in flue gas common textural properties. In this study, TEPA-modified biochar was used prepare a solid amine adsorbent for the efficient capture gas. First, porous prepared with FeCl3, Mg(NO3)2, H2O (g) as activators walnut shell...

We have previously found that the synthetic polyamine tetraethylenepentamine (TEPA) significantly delayed differentiation and prolonged expansion of cord-blood derived HPC in cytokine-supplemented cultures. Most HPC have the CD34+CD38+ phenotype, but the minority CD34+38- cells are primitive subset of HPC that have the potential for long-term repopulation in vivo. We investigated the effect of ...

Several clinical observations have suggested that copper (Cu) plays a role in regulating haematopoietic progenitor cell (HPC) development. To further study this role we used an ex vivo system. Cord blood-derived CD34+ cells were cultured in liquid medium supplemented with Kit- ligand, FLt3, interleukin 6 (IL-6), thrombopoietin and IL-3. Under these conditions, Cu content, measured by atomic abs...

Solvothermal reactions of elements Ge and Se with Ln(2)O(3) in a pentadentate polyamine, tetraethylenepentamine (tepa), produced novel neutral lanthanide-selenidogermanate polymers [{Ln(tepa)(μ-OH)}(2)(μ-Ge(2)Se(8))](n) (Ln = Eu 1, Gd 2, Dy 3). The reaction with Dy(2)O(3) in ethylenediamine (en) afforded an ionic selenidogermanate [{Dy(en)(3)}(2)(μ-OH)(2)]Ge(2)Se(6) (4). In compounds 1-3, the L...
