... sensitive to improper environmental conditions in museums and libraries either in storage or display. Accordingly, these materials face a great global problem (Abdel-Maksoud , 2006, 2011a). Some manuscripts can be degraded in serve conditions (Abdel-Maksoud and Marcinkowska, 2000 ; Abdel-Maksoud, 2011b...

... Limited Licensed re-use rights only Antioxidants SEM Inks Degradation Cellulose Immersion washing Many paper-based prints, archives and books are stained with dirt and different stains because of high acidity or products of alteration resulting from natural aging, which cause...

... of this study is to obtain a green and degradable shape memory material, calcium alginate (Ca-Alg) film was prepared and the mechanical properties, the shape memory effect of the film were investigated and confirmed. Design/methodology/approach The Ca-Alg films were prepared by Na-Alg, calcium chloride...

... is characterized by the presence of surface resonance peak in the spectra. Scanning electron microscope (SEM) images confirmed the formation of spherical particles having a size distribution in the range of 15-26 nm. The AgNPs solution showed excellent rapid catalytic activity for the complete degradation of toxic...

...Maryam Khashij; Mohammad Mehralian; Zahra Goodarzvand Chegini Purpose The purpose of this study to investigate acetaminophen (ACT) degradation efficiencies by using ozone/persulfate oxidation process in a batch reactor. In addition, the effects of various parameters on the ACT removal efficiency...

...Safa Abd El kader Mohamed Hamed; Rushdya Rabee Ali Hassan Purpose This paper aims to investigate the effect of acidity on the morphology of archeological paper, especially in the presence of colors and whether natural pigments play a role in the process of degradation. Design/methodology...

... the highest photocatalytic activity for the degradation of MO. Research limitations/implications Synthesis of these zinc porphyrins had never been reported previously. Originality/value Four novel zinc porphyrin-TiO₂ photocatalysts which could response to visible light in degradation of MO...

... properties of shellac was noticed by blending with rosin to a great extent; less degradation in the properties of blends was observed with storage compared to those of parent shellac. Research limitations/implications Because rosin possesses very high fluidity and life under heat, exact value of flow...
