“…The FTIR spectra of PSP, DPSP and CR in Figure exhibit the following absorption bands and they are assigned referring to the literatures . In the spectrum of PSP, the bands located at 711.87, 876.31, and 1420.02 cm −1 are ascribed to the in‐plane bending, out‐of‐plane bending, and asymmetric stretch vibrations of

To achieve reinforcement and coloring in one combined process of polymer production, a dye-loaded shell powder (DPSP) based on Congo red and pearl shell powder was prepared and used as a versatile bio-filler in low-density polyethylene (LDPE). The DPSP was characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy and thermogravimetric analysis. The mechanical, thermal, and colorimetric properties of prepared LDPE/DPSP composites were investigated as well. Adding DPSP could significantly increase the strength and stiffness of LDPE composites while giving an outstanding coloring performance. Moreover, the impact strength of LDPE composites was improved at lower filler loading rate, and the maximum incorporation content could reach 10 wt % with a good balance between toughness and stiffness of LDPE composites. The thermal performance studies confirmed an increase in thermal stability and heat resistance of LDPE composites with the incorporation of DPSP. V C 2016 Wiley Periodicals, Inc. J. Appl. Polym.

“…That as a result of the exposed surface area value of the porous SiO 2 as an adsorbed material, which is previously described in Figure 1 and Figure 2. Noticeable, the size of the soybean oil molecule is large with respect to the molecule size of congo red dye (Kashyout et al 2015). But the suitable value used is the 33.3 gm of crystalline porous SiO 2 /l (at congo red concentration 50 ppm).…”

Mission ATINER is a World Non-Profit Association of Academics and Researchers based in Athens. ATINER is an independent Association with a Mission to become a forum where Academics and Researchers from all over the world can meet in Athens, exchange ideas on their research and discuss future developments in their disciplines, as well as engage with professionals from other fields. Athens was chosen because of its long history of academic gatherings, which go back thousands of years to Plato's Academy and Aristotle's Lyceum. Both these historic places are within walking distance from ATINER"s downtown offices. Since antiquity, Athens was an open city. In the words of Pericles, Athens"…is open to the world, we never expel a foreigner from learning or seeing". ("Pericles" Funeral Oration", in Thucydides, The History of the Peloponnesian War). It is ATINER"s mission to revive the glory of Ancient Athens by inviting the World Academic Community to the city, to learn from each other in an environment of freedom and respect for other people"s opinions and beliefs. After all, the free expression of one"s opinion formed the basis for the development of democracy, and Athens was its cradle. As it turned out, the Golden Age of Athens was in fact, the Golden Age of the Western Civilization. Education and (Re)searching for the "truth" are the pillars of any free (democratic) society. This is the reason why Education and Research are the two core words in ATINER"s name.

“…While for ABK and ES, less obvious color variations can be observed after adsorption. Specially, the color of CR solution shifts from red to light blue after adsorption, which can be attributed to the decreasing pH value caused by \ \COOH groups on the surface of GO layers [59]. According to UV-Vis measurements (Fig.…”
