The focus of this research work is to study the effect hybrid fillers bamboo fiber and commercial glass on high density polyethylene (HDPE) matrix without interfacial coupling agent. composite was formed through melt blending method using two-roll mixing mill at temperature 160 oC shaped compression molding machine. highest value Tensile Modulus break Hardness were obtained ratio 70 % HDPE/ 15 ...

PURPOSE To evaluate the efficacy of sodium hyaluronate (HA) eye drops for the treatment of diabetic ocular surface diseases in mice. METHODS Male 6- to 8-week-old C57BL/6 mice underwent induction of type 1 diabetes with intraperitoneal injections of streptozotocin, with normal mice as the control. Topical 0.3% HA, 0.1% HA, 0.4% polyethylene glycol eye drops, and normal saline were administere...

The microporous polyethylene hollow-fiber membrane has a unique microfibrile structure throughout its depth and has been found to possess the functions of filtration and adsorption of endotoxin in water. The membrane has a maximum pore diameter of approximately 0.04 micron, a diameter which is within the range of microfiltration. Approximately 10 and 20% of the endotoxin in tap water and subter...

In this study, a pulp beating machine was used to premix the pulp fibers with high density polyethylene (HDPE) particles in water. The wet or pre-dried pulp fiber/HDPE mixture was then melt-compounded by a twin screw extruder. For further improving the dispersion of pulp fiber, some mixture was forced to pass through the twin-screw extruder twice. The resulting mixture was compression molded to...

Biocomposites have attracted a great deal of interest in research and industry sectors because they are typically lightweight, sustainable, environmentally friendly, and their thermomechanical properties can be designed to fit specific applications by tuning of their composition. In this study, mechanical properties of natural-fiber reinforced thermoplastic composite films were explored. Thermo...

This study investigated the mechanisms, using microscopy and strength testing approaches, by which the addition of maleic anhydride grafted high-density polyethylene (MAPE) enhances the mechanical properties of basalt fiber-wood-plastic composites (BF-WPCs). The maximum values of the specific tensile and flexural strengths are achieved at a MAPE content of 5%-8%. The elongation increases rapidl...

The question of increasing the reliability and durability reinforced concrete structures is a priority. One ways to increase strength using dispersed reinforcement. interest fiber-reinforced in Russia, as well Europe, Asia USA has increased significantly recent ten years. improvement physical mechanical properties noted depend on reinforcement parameters, such volume content fiber, characterist...

Two different fiber optic sensors were developed for the determination of hydrogen sulfide at ppb concentration levels; a probe-type fiber optic sensor coated with polyethylene oxide containing 0.5 M CdCl(2) and a fiber optic sensor utilizing 0.5 M CdCl(2)-pretreated filter paper as solid substrate. In the first type, CdCl(2)-polyethyleneoxide (PEO) mixture was coated onto the tip of a fiber op...

Abstract In Polyethylene terephthalate (PET) processing the raw materials are purified terephthalic acid (PTA), moderately (MTA), monoehalene glycol (MEG). The of PTA is very difficult and costly. For reducing percent we using different percentages MTA blend in PET processing. affected properties polyester melt spinning process. such as elongation, tenacity, molecular chain length, b-color IV, ...
