the development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. in petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. in this study, which is a...

in order to fabricate transparent tio2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from ti substrate by a re-anodization method. the membranes are transferred on fto glass by two different methods. at the first one, 100mm ti-isopropoxide is used to make tio2 nanoparticles for adhering tio2 nanotube membranes to fto and in the second one a commercial ti...

We propose a novel approach to fabricating flexible transparent metallic grid electrodes via evaporative deposition involving flow-coating. A transparent flexible metal grid electrode was fabricated through four essential steps including: (i) polymer line pattern formation on the thermally evaporated metal layer onto a plastic substrate; (ii) rotation of the stage by 90° and the formation of th...

background: replacement of the lost tissue is the major concerns of the plastic surgeons. expanded area should be coherent with the surrounding tissue. tissue expansion technique is the reforming methods the skin tissue scarcities. several methods for tissue expansion are available; including usage of silicon balloon and injecting fluid into the tissue expander. materials and methods: in a clin...

the potato tuber moth (ptm), phthorimaea operculella (zeller) is one of the important pests of potato in tropical regions. in this research, the toxicity of two insecticides, abamectin and deltamethrin on p. operculella was studied at 26 ± 1 c°, 65 ± 5% rh and photoperiod of 16:8 h (l: d). the concentrations were determined by preliminary dose setting experiments. distilled water was used as co...

Abstract. The present study aims at manufacturing the concrete specimens by reinforcing optical fiber and scrutinizing it with traditional concrete. were subjected to totally different things such as compressive strength tests, light‐transmission etc. results obtained for semi transparent virtually same that of specimen. transmission take a look satisfactory because Plastic Optical Fiber retain...

Visibly highly transparent indium tin oxide (ITO)/epoxy nanocomposites were prepared by dispersing polyglycidyl methacrylate (PGMA) grafted ITO nanoparticles into a commercial epoxy resin. The oleic acid stabilized, highly crystalline, and near monodisperse ITO nanoparticles were synthesized via a nonaqueous synthetic route with multigram batch quantities. An azido-phosphate ligand was synthesi...

Perfect metamaterial absorber (PMA) can intercept electromagnetic wave harmful for body in Wi-Fi, cell phones and home appliances that we are daily using and provide stealth function that military fighter, tank and warship can avoid radar detection. We reported new concept of water droplet-based PMA absorbing perfectly electromagnetic wave with water, an eco-friendly material which is very plen...

The scientific definition of polyethylene terephthalate (PET) changed for polyester in the common language. It was first manufactured 1928 and production fibre version started 1941. Nowadays, 70% artificial textile raw materials are fibres a significant amount plastic waste is generated at end life cycle clothing other products. injection moulding process introduced 1970s made it possible to de...
