In this study, a porous membrane consisting of lactic acid and cellulose acetate was fabricated using low-cost pro-environmental process. order to solve the thermostability membrane, acetate, which has higher melting point than polypropylene (PP) polyethylene (PE), used as polymer matrix. The wetting action induced plasticization effect in chain, forming several small pores during hydrostatic t...

The phosphogypsum is a by-product of the phosphate fertilizer industry. It has accumulated over several decades, and not only takes up large amount land, but also poses significant risk to environment resource waste. In order promote use phosphogypsum, its hydration hardening characteristics are studied using scanning electron microscope, X-ray diffractometer mercury intrusion porosimeter. When...

The main objective of this work was to study and to characterize cocoa butter and the binary system cocoa butter/supercritical carbon dioxide (SC-CO2). In this way, it was measured the density and the solubility of the heavy phase in equilibrium at high pressures at 40 and 50oC, as the density and compressibility of cocoa butter. The density measurements were done trough an autoclave with a sap...

BACKGROUND Crosslinked gelatin nanofibers are one of the widely used scaffolds for soft tissue engineering. However, modifying the biodegradation rate of chemically crosslinked gelatin is necessary to facilitate cell migration and tissue regeneration. Here, we investigated the optimal electron beam (e-beam) irradiation doses with biodegradation behavior on changes in the molecular weight, morph...

In this work, patterned macropores with a diameter larger than 100 μm were introduced to pristine three-dimensional (3D) nanofibrous bacterial cellulose (BC) scaffolds by using the infrared laser micromachining technique in an attempt to create an in vitro model for the culture of breast cancer cells. The morphology, pore structure, and mechanical performance of the obtained patterned macroporo...

In this study, CN-TiO₂ was modified with cryptomelane octahedral molecular sieves (OMS-2) by the sol-gel method based on the self-assembly technique to enhance its photocatalytic activity under the daylight irradiation. The synthesized samples were characterized by X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR) and porosimeter analysis. The results...

This study comprehensively assesses using Concrete Waste (CW) and Rubber tire Fly Ash (RFA) eco-recycled materials to enhance the mechanical characteristics of cohesive soil obtained from Al-Araby district in Mosul city/Iraq. These are added by 3, 6, 9% CW 12, 18, 24% RFA dry weight passed sieve (No.40), addition adding cement as an activator soil-RFA mixture. Several techniques have been used,...

Exposure of concrete to high temperatures affects its mechanical properties by reducing the compressive strength, bending… etc. Factors these have been focused on several studies over years, producing conflicting results. This article interested an important factor, that is type aggregates. For this, experimental study behavior based different types aggregates: calcareous, siliceous and silico-...

The success in the preparation of Eudragit RS100 microspheres in 0.IN HCI solution using gelatin as antiaggregating agent, encouraged the selection of an acidic drug to be encapsulated using a solvent evaporation technique [1]. Ibuprofen is a non-steroidal, anti-inflammatory, analgesic and antipyretic drug approved for use as adjunct therapy in the treatment of rheumatoid and osteoarthritis [2]...
