Photosynthetic reaction center proteins (RCs) are the most efficient light energy converter systems in nature. The first steps of the primary charge separation in photosynthesis take place in these proteins. Due to their unique properties, combining RCs with nano-structures promising applications can be predicted in optoelectronic systems. In the present work RCs purified from Rhodobacter sphae...

Sorption-desorption behavior of phenol and o-cresol was studied on two soils belonging to the Haynie series (very fine sandy loams) collected from field and forested sites. Experimental investigations focused on the effect of HRP addition on sorption and desorption of target chemicals when present in solution alone, and when present as a mixture. Addition of HRP resulted in a dramatic increase ...

Bentonite with its unique structural properties is a valuable material for environmental application. Its sorption properties are usually improved by the different ways of modification. In this work, the special sedimentation method was used for the treatment of the natural bentonite to obtain monomineral fraction of montmorillonite. The modification by iron oxide particles was used with the ai...

The effect of rare earth (RE) elements, including Ce and La, on the sorption properties of Zr-Co getters was investigated in this work. The phase evolution, microstructural characteristics of getter powders were studied by means of X-ray diffraction method, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The nanostructured Zr3Co intermetallic compound has been...

It has recently been shown that Severe Plastic Deformation (SPD) techniques could be used to obtain nanostructured metal hydrides with enhanced hydrogen sorption properties. In this paper we review the different SPD techniques used on metal hydrides and present some specific cases of the effect of cold rolling on the hydrogen storage properties and crystal structure of various types of metal hy...

Because of the high separation performance and easy preparation, mixed-matrix membranes (MMMs) consisting of metal-organic frameworks have received much attention. In this article, we report a novel ZIF-300/PEBA MMM consisting of zeolite imidazolate framework (ZIF-300) crystals and polyether block amide (PEBA) matrix. The ZIF-300 crystal size was effectively reduced by optimizing the hydrotherm...

The purpose of this study was to design a powerful fibrous sorbent for recovering precious metals such as Pd(II) and Pt(IV), and moreover for identifying its selectivity toward Pd(II) or Pt(IV) from a binary metal solution. For the development of the sorbent, polyacrylonitrile (PAN) was selected as a model textile because its morphological property (i.e., thin fiber form) is suitable for fast a...

Trace metals (e.g. Ni, Zn) leached from industrial and agricultural processes are often simultaneously present in contaminated soils and sediments. Their mobility, bioavailability, and ecotoxicity are affected by sorption and cosorption at mineral/solution interfaces. Cosorption of trace metals has been investigated at the macroscopic level, but there is not a clear understanding of the molecul...

The generalized integral transform technique (GITT) is applied to solve the one-dimensional advection±dispersion equation (ADE) in heterogeneous porous media coupled with either linear or nonlinear sorption and decay. When both sorption and decay are linear, analytical solutions are obtained using the GITT for one-dimensional ADEs with spatially and temporally variable ̄ow and dispersion coeci...
