cadmium (cd) concentration in soil solution and its bioavailability is controlled by sorption-desorption reactions. the objective of this research was to compare cd adsorption behavior in six calcareous and four acid soils. soil samples were equilibrated with 0.01 m ca(no3)2 containing 25 to 3200 mg cd l−1. results showed that the tendency for adsorption was high at low cd concentrations (0-400...

The Cover Feature illustrates ion transfer and adsorption processes of anthracycline antibiotics affected by the dendritic polymer at liquid|liquid interfaces. More information can be found in Research Article T. Takami et al.

Chick interferon has been purified to varying extents by several groups of investigators. Burke's (1961) starting material was interferon produced in chorioallantoic membranes; this was purified about 2o-fold mainly by chromatography on DEAE and SM celluloses. Zemla & Vilcek (196I) precipitated interferon, produced in chick embryo fibroblasts, with acetone or ethanol at I O ° to 1 5 ° and claim...

This study investigated arsenate and arsenite adsorption on an iron(III) oxide/silica adsorbent that had a Fe/Si molar ratio of 3. Batch experiments were conducted with regard to adsorption kinetics, isotherms, pH effects and interference of phosphate and sulfate on arsenic adsorption. The adsorption of arsenite was faster than that of arsenate. The adsorption kinetics could be well described b...

We study the adsorption behavior of Ga on ~0001! GaN surfaces combining experimental specular reflection high-energy electron diffraction with theoretical investigations in the framework of a kinetic model for adsorption and ab initio calculations of energy parameters. Based on the experimental results we find that for substrate temperatures and Ga fluxes typically used in molecular-beam epitax...

The non-isothermal transformation rate curves of metallic glasses are analyzed with the Master Curve method grounded in the Kolmogorov-Johnson-Mehl-Avrami theory. The method is applied to the study of two different metallic glasses determining the activation energy of the transformation and the experimental kinetic function that is analyzed using Avrami kinetics. The analysis of the crystalliza...

The desiccant material is a material which has ability to remove moisture from air. According to the physical and chemical properties, there are two types of desiccant material namely solid desiccant material and liquid desiccant material. In this experimental study, solid desiccant material is used. Solid desiccant material adsorbs moisture from air due to water vapour pressure difference. Som...

widely known to possess potent anti-infl ammatory properties by reducing the production of pro-infl ammatory cytokine production, or stimulating the production of anti-infl ammatory cytokines, including interleukin-10 (Otterbein et al., 2003; Paine et al., 2010). Additionally, HO-1 over-expression protects against cytotoxicity induced by NO (Son et al., 2005). HO-1 expression is induced by bind...
