Novel biomaterials for diagnostics and therapeutics of biomedical issues have been considered using science health care. Halloysite nanotubes (HNTs) are naturally occurring aluminosilicate clay. Because their unique hollow tubular structure, biodegradability, mechanical surface properties, they drawn the attention researchers to a variety applications. HNTs inorganic natural aluminosilicates th...

The main objective of this work is to present an experimental study on the use textile reinforced mortar improve masonry infill walls out-of-plane behaviour. campaign comprises flexural strength tests parallel horizontal bed joints 10 specimens made up hollow clay bricks, five them unstrengthened and remaining strengthened. Cantilever were carried out. efficiency strengthening was assessed effe...

in this study, the influence of the salts as an additive on the performance of the membrane was investigated and an extensive work was performed to optimize pvdf hollow fiber membranes through a response surface methodology (rsm). the prepared membranes were characterized by sem, contact angle and lep measurement. then, the rsm was used for the optimization of surface pore size, porosity and hy...

clay minerals are considered the most important components of clastic reservoir rock evaluation studies. the shurijeh gas reservoir formation, represented by shaly sandstones of the late jurassic-early cretaceous age, is the main reservoir rock in the eastern kopet-dagh sedimentary basin, ne iran. in this study, x-ray diffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopic (s...

In cylindrical continua, hoop stresses are induced due to the circumferential failure. This mainly happens when the cylinder is subjected to mechanical loads which vary in the circumferential directions. On the other hand, radial stress is stress in the direction of or opposite to the central axis of a cylindrical body. In the present study, the influence of curvilinear anisotropy on the radial...

this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...
