Abstract: This paper presents the results of an experimental study to investigate the effects of two types of graphene, dried (DG) and hydrated graphene (HG), when enhancing the interfacial and tensile mechanical properties of ...

Abstract: Solar energy is a promising source of energy because it is abundant and harmless to the environment. One of the critical issues involving solar energy is the layout design of sunlight concentrators. This study presents a ...

Abstract: A two-dimensional (2D) time-domain waveform tomography technique is presented for detection of delamination in concrete bridge decks. Measured ultrasonic surface wave fields were inverted using a full waveform inversion ...

Abstract: Per- and polyfluoroalkyl substances (PFAS) can occur in groundwater at elevated concentrations due to use in numerous commercial and industrial applications. Foam fractionation, which utilizes the surfactant properties of ...

Abstract: A new ultraseismic waveform tomography technique for a bounded medium is presented for evaluation of concrete bridge abutments, or wall piers, and the supporting soil and rock underneath them. Ultraseismic wave fields are ...

Abstract: A shear strength model is proposed for reinforced concrete bridge columns with multispiral transverse reinforcement. The proposed model consists of a proposed discrete computational shear strength model for multispiral ...

Abstract: Bench-scale experiments were performed to evaluate poly- and perfluoroalkyl substance (PFAS) desorption from vadose zone soils collected at a site historically impacted with aqueous film-forming foam (AFFF). A sequential ...
