Deoxyribonucleic Acid (DNA) has been recently found to be an efficient renewable and environmentally-friendly flame retardant. In this work, for the first time, we have used waste DNA from fishing industry to modify clay structure in order to increase the clay interactions with epoxy resin and take benefit of its additional thermal property effect on thermo-physical properties of epoxy-clay nan...
Hybrids based on recycled high density polyethylene (RHDPE) and organic clay were made by melt compounding. The influence of blending method, compatibilizers, and clay content on clay intercalation and exfoliation, RHDPE crystallization behavior, and the mechanical properties of RHDPE/clay hybrids were investigated. Both maleated polyethylene (MAPE) and titanate could improve the compatibilizat...
Fractions, uptake and fixation capacity of phosphorus and potassium in three contrasting soil orders
A controlled greenhouse experiment was conducted to study the fraction, uptake and fixation of phosphorus (P) and potassium (K) in three soils with contrasting characteristics. The experiment was carried out in two phases, viz., sorghum-Sudangrass depletion and test crop experiment with maize with three levels of fertility status (depleted, original and fertilized with 40 mg kg-1 P and K) and t...
Bone ash waste can be used to fabricate clay ceramic bricks, consequently managing their pollution of the environment. This is because bone (BA) and predominantly consist calcium alumina-silicate, respectively, which are components brick (CCB) materials. study aims investigate effect temperature on physio-chemical mechanical properties CCB. Different percentages (5%, 10%, 15%, 20%) were added h...
Soil is one of the common materials used in construction industry whether it for groundwork, infrastructure or as building materials. However, issues arise when structures are built on soft soil such clay that causes instability and settlement. In order to improve strength, various methods had been adopted by researchers use stabilizers like lime, cement fly ash. This paper presents improvement...
One of the most effective and recognizable way to solve energy resource consumption problems in cement industry is development blended Portland with different combinations mineral additives. The complex additives based on combination calcined clays limestone one promising directions. aim this work was study influence kaolinitic clay kaolinite content 80 % calcite 99 stone hydration products at ...
Adhesion and homogeneity of the coating-substrate were analyzed on basis establishment coating mineralogy. Substrate raw materials used kaolin clay a calcined alumina 4 µm; series higher density ceramic coatings deposited using aluminas 0.5 µm µm, silica fume, talc. The dip technique was applied to all substrates later sintered at 1300 ºC. Shrinkage mixtures substrate separately evaluated. X-ra...
The mechanical and electrical characteristics of films, buckypapers and fiber materials from combinations of clay, carbon nanotubes (CNTs) and chitosan are described. The rheological time-dependent characteristics of clay are maintained in clay-carbon nanotube-chitosan composite dispersions. It is demonstrated that the addition of chitosan improves their mechanical characteristics, but decrease...
The effects of (+ )-catechin adsorption to the alumina surface were studied by -potential and surface free energy determination. The presence of catechin causes essential changes in the alumina -potential, which at the concentration slightly higher than 10 M reverses from the positive into negative one. At constant concentration of catechin (10 M), the effect on -potential of alumina as a funct...
This paper presents a part of our work on understanding the effect of nanoscale pore space confinement on ion sorption by mesoporous materials. Acid-base titration experiments were performed on both mesoporous alumina and alumina particles under various ionic strengths. The point of zero charge (PZC) for mesoporous alumina was measured to be approximately 9.1, similar to that for nonmesoporous ...
