Statistical analysis of an experimental database on residual flexural strengths of fiber reinforced concretes: Performance‐based equations

Structural Concrete, Volume 23, Issue 5, Page 3140-3153, October 2022., 2022
Abstract The postcracking capacity of fiber reinforced concrete (FRC) mainly depends on the content, material, and geometry of the fibers considered. Even though the general influence of these factors on FRC behavior has been extensively addressed, the uncertainty of the FRC performance prediction along with the variability of the results still poses a

Experimental Characterization and Statistical Analysis of Water‐Based Gold Nanofluids for Solar Applications: Optical Properties and Photothermal Conversion Efficiency

Solar RRL, Volume 6, Issue 7, July 2022., 2022
In this article, the use of water‐based gold nanofluids is proved to enhance the photothermal conversion efficiency (PTE) of direct solar absorption collectors. Nanofluids (NFs) are colloidally stable and an increase in PTE of up to 121% with respect to water is achieved.

Macro‐porous permeability aspects of MgSO4 salt hydrate foams for energy storage applications

Journal of Applied Polymer Science, Volume 139, Issue 15, April 15, 2022., 2022
A macroporous silicone foam, able to contain the magnesium sulfate, was chosen as matrix for the reversible hydration/dehydration process of the salt hydrate for thermochemical energy storage applications. In particular, a correlation between microscopic and macroscopic properties of the composite foams was addressed.

What feeds on Quercus ilex L.? A biogeographical approach to studying trophic interactions in a Mediterranean keystone species

Diversity and Distributions, Volume 28, Issue 1, Page 4-24, January 2022., 2022
Abstract Aim Holm oak (Quercus ilex L.) is regarded as a keystone plant species. Trophic interactions may affect the distribution and abundance of phytophagous species, but the number of arthropod species that use holm oak as a food resource and their levels of host specificity are not yet known.
