Assessing downstream passage of European silver eel at a tidal pumping station: acceleration as a proxy for eel activity

Movement Ecology
Background To complete their lifecycle, diadromous fish often need to pass anthropogenic barriers in regulated rivers and estuaries (e.g., pumping stations, weirs, hydropower facilities). The safe and timely passage of the endangered catadromous European

Optimal Pumping Flow Algorithm to Improve Pumping Station Operations in Irrigation Systems

Agriculture
In Spain, irrigated agriculture is the most water-intensive sector, consuming around of 80% of water resources. Moreover, irrigation water distribution systems are the infrastructure by which one-third of water resource losses take place.

Comparative Analysis of Al2O3/Water–TiO2/Chlorophyll Hybrid Nanofluids in a Photovoltaic–Thermal Solar Water Heating System

Energy Science &Engineering, EarlyView.
TiO2/chlorophyll bio‐hybrid nanofluid achieved the highest PVT performance, increasing thermal efficiency to 38.74% and overall efficiency to 51.35%, compared with 35.96% and 48.45% for Al2O3/water and 27.77% and 40.18% for water. The results demonstrate the potential of bio‐hybrid nanofluids for high‐efficiency solar thermal energy conversion ...

Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

FlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...
