Research ArticleOpen accessIn the keywordsRaman Spectroscopy of Protein Crystal Nucleation and GrowthPechkova Eugenia, Maksimov, Georgy et al.Using Raman spectroscopy and the lysozyme as model system, we investigate the differences in protein conformation before and after Langmuir-Blodgett nanotemplate-induced crystal nucleation and growth. It was found, that the main difference in lysozyme conformation is associated to the higher amount of S-S bonds in lysozyme of LB crystals, probably in C-end of protein, resulting in the higher stiffness of … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 8 Dec 2014 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Using Crumb Rubber Modified Binder in an Asphalt PavementSayed Mohamad Soleimani, Alanoud Faheiman, Zainab MowazeIn this study, laboratory investigations have been carried out to characterize and demonstrate the improved performance of asphalt after modifying it with crumb rubber. The study has been divided into two main parts. Firstly, the physical characterizations of crumb rubber modified bitumen with different percentages of crumb rubber have been evaluated using penetration, softening point, viscosity, ductility and thin film … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 14 May 2020 · 8,384 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical and Structure Analysis of ZnO:Al FilmNeilo Marcos Trindade, Michel Chaves, José Roberto Ribeiro Bortoleto et al.ZnO and ZnO:Al are wide-bandgap semiconductors which have many applications, mainly as transparent conducting films. Thin films of these compounds were deposited onto glass and silicon substrates by RF magnetron sputtering for the investigation of structural and optical characteristics. The XRD results show that the films present wurtzite structure. The formation of a polycrystalline film having a preferential crystallographic orientation … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Oct 2017 · 7,862 accessesView PDFCite

Research ArticleOpen accessIn the abstractInvestigating Bio-Char as Flow Modifier and Water Treatment Agent for Sustainable Pavement DesignRenaldo Walters, Shamim A. Begum, Elham H. Fini, Taher M. Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of Ultraviolet (UV) rays. UV rays cause asphalt to oxidize faster, which results in the deterioration of asphalt's rheological characteristics that can lead to pavement distresses. This paper investigates merits of bio-char to improve asphalt aging susceptibility by blending one control binder (PG 64-22) and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 9,055 accessesView PDFCite
