Energy Science &Engineering, Volume 14, Issue 2, Page 764-779, February 2026.Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

Advanced design and optimization of wind turbines based on turbine theories [PDF]
, 2019 A review of wind turbine technology showed that many flaws in both the flow models and computations are involved in the traditional fundamentals. While traditional methods for design and computation are all based on the airfoil theory, a new method based

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 116-133, January 2026.We show that pH and neutralization strategy strongly influence the growth, pellet morphology, and organic acid production of Aspergillus oryzae. Acidic and alkaline conditions lead to hairy, dispersed pellets, while near‐neutral environments favour compact pellet formation.

Toward the Development of a Uranium‐Based Redox‐Flow Battery
ChemSusChem, Volume 19, Issue 1, January 2026.The first all‐uranium‐based electrochemical cell has been realized using simple [UIV/V(tBuacac)4]0/+ and [UIII/IV(N(SiMe3)2)4]–/0 complexes, readily available in convenient, scalable syntheses, as anolyte and catholyte couples. Operating at a cell potential of 2.2 V with a projected energy density of 0.357 Wh kg–1, this system establishes a foundation ...

Diagnostics and prognostics utilising dynamic Bayesian networks applied to a wind turbine gearbox [PDF]
, 2012 The UK has the largest installed capacity of offshore wind and this is set to increase significantly in future years. The difficulty in conducting maintenance offshore leads to increased operation and maintenance costs compared to onshore but with better
