Finite Element Analysis (FEA) of Helical Tidal Turbine

open access: yes
The spiral turbine assembly can provide unidirectional rotation at ultra-high speed, lower than the multi-directional ultra low head fluid provided. The assembly consists of a series of spiral turbine units or modules arranged vertically or horizontally to harness the power of water or wind, for example.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

High‐Performance Solid‐State Lithium Batteries via Dipole‐Matching: Enabling Compact Polymer Microstructure and Stable Interfaces

open access: yesCarbon Energy, EarlyView.
A dipole–matching strategy is proposed to engineer PVDF‐HFP solid polymer electrolytes by incorporating 3,5–bis(trifluoromethyl)benzoic acid. Dipole interactions regulate polymer nucleation and phase alignment, forming compact microstructures, while controlled FSI– decomposition induces a LiF–rich interphase, enabling fast Li+ transport, uniform ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Overcoming Cell Fixture Challenges in High‐Pressure Operation of Solid‐State Batteries

open access: yesEnergy Science &Engineering, EarlyView.
Accurate application of high uniaxial pressure remains a limiting factor in large‐format solid‐state battery testing. A spring‐loaded fixture employing deflection‐based pressurization enables precise, homogeneous, and reproducible pressure application without expensive in‐fixture sensors, providing a robust framework for systematic investigation of ...
