With the increasing adoption of renewable energy sources globally, hydropower contributes
significantly to energy generation through various schemes ranging from big to small-scale …

The N-doped three-dimensional (3D) needle bridge connection core-shell structure N-CoS
2 @Co 3 O 4 synthesized in this work was prepared by simple hydrothermal and high-…

Owing to its ability to handle large flows, an axial flow pump as turbine (PAT) can generate
considerable amounts of electricity in small-scale hydropower plants. However, a PAT's …

Background Hearing loss affects access to spoken language, which can affect cognition and
development, and can negatively affect social wellbeing. We present updated estimates …

Pump-as-turbine stations with ultra-low head often face the deterioration risk during load
rejection operations when the demands in water delivery and power generation are satisfied. In …

A novel 1D Co 3 O 4 /polyethyleneimine-carbon nanotubes composites (CoPCNTs) have
been successfully synthesized via hydrothermal method at different temperature. The CNTs …

Biomorphic SnO 2 nanoparticles with a mesoporous structure were synthesized using simple
one-step hydrothermal method with SnCl 2 as the raw material and hemp stems as the bio-…

For most of low-head pump stations, pumps simultaneously undertake important tasks such
as flood control, irrigation and drainage where more attention should be paid on involved …

A simple noncovalent chemical approach and hydrothermal method were used for effectively
riveting Co3O4 nanocrystals to branched polyethylenimine (PEI) functionalized Ti3C2Tx …

Large-eddy simulation is performed to study the turbulence statistics and flow structures of
the water past a rotating axial-flow pump under different flow-rate working conditions. A novel …
