The effects of positively charged nylon and depth (cellulose-diatomaceous earth) filters on endotoxin removal from various solutions were evaluated. The charged filter media removed significant amounts of Escherichia coli and natural endotoxin from tap water, distilled water, sugars, and NaCl solutions; no significant removal of endotoxin was observed with negatively charged filter media. The e...

Advanced carbon materials are important for the next-generation of energy storage apparatus, such as electrochemical capacitors. Here, the physical and electrochemical properties of carbonised filter paper (FP) were investigated. FP is comprised of pure cellulose and is a standardised material. After carbonisation at temperatures ranging from 600 to 1700 °C, FP was contaminant-free, containing ...

The Imugard IG 500 cotton wool filter and the Cellselect cellulose acetate filter were adapted for filtration of leucocytes from packed cell transfusions at the bedside. Sixty five transfusions were given via the Imugard IG 500 filter and 54 transfusions were given via the Cellselect filter. Packed red cell concentrates from the National Blood Transfusion Service provided for routine blood tran...

A filtration technique for the gentle lysis of erythrocytes has been developed using cellulose triacetate membranes. When cell suspensions are filtered under nitrogen pressure, lysis occurs at the surface of the filter in such a way that the cell ghosts are retained on the filter. The contents of the cell are extruded through the pores of the filter without mixing with the cell suspension. Cell...

In this paper, we present a facile and cost-effective method to obtain superhydrophobic filter paper and demonstrate its application for efficient water/oil separation. By coupling structurally distinct organosilane precursors (e.g., octadecyltrichlorosilane and methyltrichlorosilane) to paper fibers under controlled reaction conditions, we have formulated a simple, inexpensive, and efficient p...

Use of porous cellulose ester membranes in the primary isolation and size determination of pleuropneumonia-like organisms. J. Bacteriol. 85:134-136. 1963.-Millipore filters were used in the primary isolation and sizing of a number of strains of pleuropneumonia-like organisms (PPLO). Maximal pore ...

Cellulose is the most abundant material in earth, it considered a renewable polymer of cell walls wood and plant cells, their interest use different field purpose extracting namely: cellulose native (cotton), transformation into sheets (paper filter paper), cupric cellulose, zinc (industrial applications), functionalization cellulosic materials printed electronics, textile, treatment, medicine,...

The hydrolysis of Whatman no. 1 filter paper by purified cellulolytic components from Trichoderma reesei and the synergistic action of binary combinations of these enzymes on the same substrate were investigated. At 20 milligrams filter paper, enzyme concentrations needed to obtain half-maximal hydrolysis rates (KE values) were in the 3-4 microM range for the cellobiohydrolases (CBHs) and 0.05-...

Given that the supply of several rare earth elements (REEs) is sometimes limited, recycling REEs used in various advanced materials, such as Nd magnets, is important for realizing efficient use of REE resources. In the present work, the feasibility of using DNA for REE recovery and separation was examined, along with the identification of the binding site of REEs in DNA. In particular, a DNA-...
