natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

The problem of improper disposal polymeric waste is increasingly in present. Thus, the use biodegradable polymers a good alternative, especially for packaging. Compostable and such as PHBV can be completely degraded, making them ideal. But short processability window fluid instability an important drawback to wider application this polymer pure form. Production composite materials has been indi...

this study has been conducted in order to investigate the effect of using onp recycled fibers on the mechanical and optical properties of local mixed hardwoods kraft pulp at iran wood and paper industry (chooka). onp and virgin kraft pulp have been prepared from chooka’s waste paper storage and pulping digester, respectively. onp has been repulped in the common method as used by paper recycling...

Purpose – A large amount of post-consumer carpet waste is discarded into landfills. The need to recycle this waste is increasing due to the lack of available landfill spaces in many parts of the world, environmental concerns, and resource conservation. The purpose of this paper is to explore the use of this waste for a low-cost, high-volume application. Design/methodology/approach – Fibers from...

The engineering of large (thickness > 100 μm) tissues requires a microvascular network to supply nutrients and remove waste. To produce microvasculature in vitro, a scaffold is required to mechanically support and stimulate endothelial cell (EC) adhesion and growth. Scaffolds for ECs are currently produced by patterning polymers or other biomaterials into configurations which often possess isot...

Degradation of acrylic water base color from synthetic wastewater by the Fenton process was performed. Experiments were conducted on the sample containing 100 and 400 mg/l of Acrylic water base color. The study was performed for searching optimum values of FeSO4 and H2O2 concentration, pH and temperature. The H2O2 requirement seems to be re...

The global demand for acrylic acid (AA) is increasing due to its wide range of applications. Due this growing demand, alternative AA production strategies must be explored avoid the exacerbation prevailing climate and warming issues since current involve fossil resources. Investigations regarding therefore constitute an important research interest. present study assesses waste apple pomace (WAP...

The chemical composition, anatomical characteristics, lignin distribution, and cell wall structure of oil palm frond (OPF), coconut (COIR), pineapple leaf (PALF), and banana stem (BS) fibers were analyzed. The chemical composition of fiber was analyzed according to TAPPI Methods. Light microscopy (LM) and transmission electron microscopy (TEM) were used to observe and determine the cell wall st...

degradation of acrylic water base color from synthetic wastewater by the fenton process was performed. experiments were conducted on the sample containing 100 and 400 mg/l of acrylic water base color. the study was performed for searching optimum values of feso4 and h2o2 concentration, ph and temperature. the h2o2 requirement seems to be related to initial cod of the sample. feso4/ h2o2 ratios ...
