A combination of atomic force microscopy (AFM) and reflection interference contrast microscopy (RICM) was used to measure simultaneously the interaction force and the spatiotemporal evolution of the thin water film between a bubble in water and mica surfaces with varying degrees of hydrophobicity. Stable films, supported by the repulsive van der Waals-Casimir-Lifshitz force were always observed...

In the processes of protein synthesis and folding, newly synthesized polypeptides are tightly connected to the macromolecules, such as ribosomes, lipid bilayers, or cotranslationally folded domains in multidomain proteins, representing a hallmark of de novo protein folding environments in vivo. Such linkage effects on the aggregation of endogenous polypeptides have been largely neglected, altho...

Abstract A polymer-enhanced bentonite-sand mixture has been widely used as a clay liner. This research focuses on the potential use of chitosan natural polymer mixed with bentonite liner base material. The is type calcium bentonite, which easily obtained in market. Meanwhile, produced from shrimp shell waste and also available process mixing percentage 2–6% was carried out using certain method,...

The usage of wastes of baggase would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of bagasse-bentonite. The prepared adsorbent was applied to remove Cd2+ from aqueous solution. The characterization data of the adsorbent were analyzed using XRF and FTIR methods. The XRF test r...

Short term in vitro incubations were used to evaluate the effect of fumaric acid bentonite coupled addition on rumen fermentation effeciency. Ruminal contents from five steers were used for preparation of inoculums of mixed rumen microorganisms that were used in generatation of three treatment systems, negative control, fumaric acid treated, and fumaric acid – bentonite coupled treated. The fer...

Spectroscopic analysis was used to study the effect of wine processing on phenolic composition. Various classes of phenolic compomtds were detected and characterized by ultraviolet (UV) and Infrared (IR) spectroscopy in white grapes of Sauvignon Blanc and French Colombard, as well as in wines prepared from these grapes. Comb/ned treatment with bentonite, egg albumin and Polycinr AT decreased th...

Abstraet--Jordanian natural kaolin and bentonite show good catalytic activity towards debutylating 2tert-butylphenol, and varying debutylation vs. isomerization selectivity after acid activation. The resulting catalytic activity of these samples is dependent on the acid employed for activation; the samples treated with acetic acid showed relatively low conversions, whereas those treated with hy...

The usage of wastes of algae would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of algae waste-bentonite. The prepared adsorbent was applied to remove Pb2+ from aqueous solution. The characterization data of the adsorbent were analyzed using FTIR and SEM-EDX methods. The FTIR...

Chemical modifications of clay to remove methylene blue (MB) from aqueous solutions at room temperature were compared. Natural bentonite (NC) was modified by cation exchange with hexadecyltrimethylammonium chloride (HC), bencyltriethylammonium chloride (BC), and tetramethylammonium chloride (TC) to reverse the surface polarity of the hydrophilic bentonite. The adsorption of MB was studied and f...

abstract among synthetic carriers, dendrimers with the more flexible structure have attracted a great deal of researchers' attention in the field of gene delivery. followed by the promising results upon hydrophobic modification on polymeric structures in our laboratory, alkylcarboxylated poly (propylenimine)-based carriers were synthesized by nucleophilic substitution of amines with alkyl moiet...
