One of the practical ways to overcome adverse environmental effects plastic bottle waste is implement bottles into concrete, one most widely used materials in construction industry. Plastic are mainly made polyethylene terephthalate (PET) and can be as a fiber reinforce concrete. In recent years, PET fiber-reinforced concrete (PFRC) has attracted researcher attention, several experimental studi...

Background. Acrylic resins used in restorative dentistry are the most popular denture base material, because they have good optical properties and small solubility in body fluids. However their mechanical properties are limited and therefore acrylic resins require different methods of reinforcement one of which can be application of different kinds of fibers. Objectives. To investigate the effe...

This paper presents the influence of Hybrane H 1500 as a hyperbranched polymer on kinetic parameters of dyeing compounded fiber grade PET polyethylene terephthalate at boil temperature. C.I. Disperse Red 324 as a disperse dye was used for dyeing compounded fiber grade PET. The result was compared with corresponding properties of virgin PET. The dyeing rate constants and diffusion coefficients a...

The preliminary screening of microplastics (MPs) in sewage sludge from centralized industrial wastewater treatment plants (WWTPs) Da Nang city Viet Nam was investigated this study. MPs samples were collected the two WWTPs namely Hoa Cam (HC) and Khanh (HK). obtained results indicated that concentrations HC HK 1,164 3,745 particles/kg dry weight, respectively. sizes varied 1.6 to 5,000 μm, which...

BACKGROUND The impact strength of denture base resin is of great concern and many approaches have been made to strengthen acrylic resin dentures. The objective of this study was to compare the impact strength of the denture base resin with and without reinforcement and to evaluate the impact strength of denture base resin when reinforced with stainless steel mesh, glass fiber, and polyethylene ...

This paper provides experimental results to investigate the mechanical properties of sustainable strain-hardening cement composite (2SHCC) for infrastructures after freeze-thaw actions. To improve the sustainability of SHCC materials in this study, high energy-consumptive components-silica sand, cement, and polyvinyl alcohol (PVA) fibers-in the conventional SHCC materials are partially replaced...

o bjectives: heat-polymerized acrylic resin has been the most commonly used denture base material for over 60 years. however, the mechanical strength of acrylic resin is not adequate for long-term clinical performance of dentures. consequently, fracture is a com- mon clinical occurrence, which often occurs in the midline of denture base.this study aimed to evaluate the efficacy of cold cure and...

Wind turbine blades are easily struck by lightning, a phenomenon that has attracted more and more attention in recent years. On this subject a large current experiment was conducted on three typical blade sandwich structures to simulate the natural lightning-induced arc effects. The resulting damage to different composite materials has been compared: polyvinyl chloride (PVC) and polyethylene te...

In this study layer by layer (LBL) self-assembled coatings of hyaluronic acid (HA) and cationized gelatin (CG) were used to modify polyethylene terephthalate (PET) artificial ligament grafts. Changes in the surface properties were characterized by scanning electron microscopy, attenuated total reflection Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and contact ...
