This report describes an improvement made to the horizontal cell electrophoresis methodology. It involves using two liquid layers differing in density to produce an interface described as a “density cushion”. The electrophoretic system that employed an anti-convective porous matrix to separate red blood cells (RBC) and charged dyes effectively was found to be unsuitable for some other mammalian cells. The “density cushion” method was found to be more versatile and applicable to studies on the separation of a variety of cell types. The experiments described show the differences between the electrophoretic mobilities of a human eosinophilic leukaemia cell line (Eol-1) and RBC, both with and without the modification of the cell surface properties.

Chemical and elemental composition of selected lignocellulose materials was determined and next the materials were used to produce a series of active carbons for electrochemical hydrogen adsorption under strictly repeatable conditions. Chemical activation (900oC) with the application of KOH (4:1) was used for the development of the porous structure. Prior to activation all materials were pyrolysed at 700oC applying a slight temperature increase rate (3oC/min). Produced active carbons had diverse parameters of the porous structure and considerable BET surface areas ranging from 2178 to 2815 m2/g. Experiments showed feasibility of electrosorption of hydrogen on the surface of active carbons produced from commonly available, cheap and frequently waste lignocellulose materials. The type of the applied precursor has a significant effect on the development of the porous structure and hydrogen sorption. The highest hydrogen sorption value of Hc=1.91% weight and Hc=1.90% weight were obtained on AC from cherry stone shells and from oak wood.
