The objective of this research is to characterize the reduction of volatile organic compounds (VOCs) from bituminous materials resulted from activated carbon. A gas chromatography-mass spectrometer (GC-MS) was used to separate VOC components, and ultraviolet-visible spectrophotometry (UV-Vis) was conducted to quantify the amount of VOCs. Results indicated that activated carbon had an excellent suppression effect on VOCs’ emission process. Adding activated carbon to the bitumen binder did not change its chemical compounds, but did result in a significant reduction of VOCs. The weight of VOCs from the bitumen binder reduced by around 30% when it was modified with activated carbon. Half of VOC emissions can be reduced by introducing activated carbon into styrene-butadiene-styrene (SBS)-modified bitumen. A scanning electron microscope (SEM) showed the high porosity and large internal surface area in the active carbon, resulting in lower VOC emissions when it was introduced into bituminous materials.
This paper explores innovative practices in theatrical and film art design, analyzing how these practices integrate artistic expression with technological advancements. Through literature review and empirical analysis, we focus on case studies in film production and stage design to examine the application of modern technologies in artistic design and their impact on creative innovation. The study reveals that innovative practices not only expand the boundaries of art design but also enhance emotional connections between audiences and productions. Finally, the paper outlines future research directions and technological trends in this field.
Reversible poly(vinyl alcohol) electrospun nanofibrous membrane modified with spirolactam–rhodamine derivatives for visible detection and removal of metal ions.
Effect of zeolite 4A on the properties of styrene-butadiene-styrene (SBS) asphalt binders was studied. The thin film oven test (TFOT) and pressure aging vessel system (PAV) were used to investigate the effect of zeolite 4A on the short-term and long-time aging properties of SBS asphalt. The effect of zeolite 4A on the rheological properties was studied using dynamic shear rheometer (DSR) test. The variation of the softening point, penetration, ductility of asphalt binder indicated that the addition of zeolite 4A can improve the aging property and high temperature stability of SBS asphalt, especially when the content of it was 6wt%. Furthermore, the results of the temperature sweeps by the DSR on SBS asphalt and that modified by 6wt% zeolite 4A showed that the rutting resistance and high temperature stability of SBS asphalt were improved when the zeolite 4A had been added.
