this paper investigated the effects of combining fibers with self-consolidating concrete (scc). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (pps) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. all plans were subjected to fresh concrete tests. for mechanical behavior of...

An increasing number of organic light-emitting diodes (OLEDs) is nowadays based on the use polymers as emissive material. For this material class in particular, solution-processing OLEDs has gained traction both research and industry. However, order to access multilayer systems, orthogonal solvents must be used prevent dissolution previously prepared layers. The crosslinkers can facilitate prod...

nitric oxide is a short-lived mediator, which can be induced in a variety of cell types and produces many physiologic and metabolic changes in target cells. it is important in many biological functions and generated from l-arginine by the enzyme nitric oxide synthase. nitric oxide conveys a variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxici...

Understanding of the potential leaching plastic particles, particularly nanoplastics (NPs), from food packaging is crucial in assessing safety materials. Therefore, objective this study was to investigate exposure risks by simulating release NPs various materials, including polypropylene (PP), general casting (GCPP) or metalized (MCPP), polyethylene (PE), terephthalate (PET), and polyphenylene ...

• Recycled carbon fibres were used for laminate interlayer toughening. The commingled rCFs/Polyphenylene-sulfid showed excellent toughening performance. mode-I and mode-II fracture energies of the significantly increased by 220% 105%, respectively. This study demonstrated an attractive application recycled fibres. Exploring routes effective use (rCFs) is critical to close loop in life cycle wor...

morphology of surface oxide film formed during pouring of molten magnesium alloy has been investigated. due to surface turbulence during casting, the oxide film necessarily makes folded cause in a dry surface to dry surface mode creating a double oxide film with the volume of air that can be encapsulated between folds of the film and this led to make gas bubbles or shrinkage cavities form. thes...
