    Improve Efficiency of Photovoltaic/Thermal Systems using Porous Materials: An Experimental Study by H. Farzan

    Published 2025-07-01
    “…For this purpose, an experimental setup was fabricated, and two scenarios were investigated: a non-porous PV/T and a porous one in which steel wool was used as a porous material. The acquired results revealed that using steel wool reduces the PV temperature by 9.9 oC and increases the outlet temperature by 4.41 oC at the air flow rate of 0.17 kg/s. …”

    Effect of Internal Curing with Superabsorbent Polymers on Bond Behavior of High-Strength Concrete by Xiao Lei, Rui Wang, Hanwan Jiang, Faxiang Xie, Yanni Bao

    Published 2020-01-01
    “…Meanwhile, the bond performance between reinforcing steel and SAP HSC concrete remains unknown. In this paper, the bond performance of HSC mixed with SAP is studied by pull-out tests, and the results were obtained as follows: (1) the bond strength of HSC mixed with SAP increased first and then decreased with the increase of SAP content; (2) the slip at ultimate bond strength of HSC with SAP decreased with the increase of compressive strength; (3) a prediction model of the stress-slip relationship between steel rebars and HSC was established.…”
