Cycling Performance of Sodium‐Metal Chloride Battery Cells and Modules Based on Iron and Zinc

open access: yesAdvanced Energy Materials, EarlyView.
High‐utilization sodium–metal chloride cells with a mixed‐metal Fe, Zn, NaCl cathode enable efficient high‐temperature cycling (300°C) while reducing cost and environmental impact. Near‐theoretical capacity and high efficiency are achieved in single cells.

Rotating turbine blade pyrometer

open access: yes, 1974
Non-contacting pyrometer system optically measures surface temperature distribution on rotating turbine blade, comprising line-by-line scan via fiber optic probe. Each scan line output is converted to digital signals, temporarily stored in buffer memory,

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs

open access: yesAdvanced Intelligent Discovery, EarlyView.
A vision‐based add‐on transforms commercial spin coaters into autonomous modules of Self‐Driving Labs. Combining a width‐scaled U‐Net with classical geometric analysis, the system simultaneously measures contact angles and estimates substrate pose using a single camera.

Influence of Fat Oil Binding Capacity on Shelf‐Life and Consumer Acceptance of a Chocolate‐Based Model System

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In chocolate‐coated products, oil migration can lead to chocolate softening and discoloration, filling hardening, and reduced consumer acceptance. This study examined three fats (soy‐, palm‐, and palm‐kernel (PK) based), crystallized under different conditions (cooling rate and high intensity ultrasound (HIU)) with differing oil binding ...

Influence Mechanism of Structural Parameters of a Novel Sleeve‐Shaft Counterrotating Hydrodynamic Cavitation Reactor on Cavitation Characteristics and Performance

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study systematically investigates the cavitation characteristics of a novel sleeve‐shaft counterrotating (SSCR) hydrodynamic cavitation reactor using computational fluid dynamics (CFD). Based on the RANS framework combined with the SST k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model, the temporal–spatial evolution of ...

Three-Dimensional Analysis of Rotordynamic Fluid Forces on Whirling and Cavitating Finite-Length Inducers

open access: yes, 2002
The paper investigates the linearized dynamics of the threedimensional flow in finite-length helical inducers with attached blade cavitation, with the purpose of understanding the impact of the cavitation response on the rotordynamic forces exerted by ...

A preliminary experiment in resonance testing a rotating blade [PDF]

open access: yes, 1969
An experiment to excite the flapping modes of a two-blade nonarticulated model rotor is described. The experiment was designed to develop a method of exciting a blade whilst it is rotating, and to measure the change of natural frequencies due to ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Simulation of Flexible Mechanisms in a Rotating Blade for Smart-Blade Applications

open access: yes, 2012
The active Gurney flap technology is investigated to improve the performance of rotorblades by allowing helicopter blades to further control the lift unbalance that rises at high speed and by damping vibration loads on the rotor hub. This technology needs validation by wind tunnel testing of a scaled model blade under rotational loading.

Design, construction and testing of a simple blade pitch measurement system for small wind turbines

open access: yes, 2007
Reliability in performance is a key factor in ensuring the sustainable operation of a small wind turbine. Despite the great potential of small wind turbines to provide electric power, particularly in remote areas, many small wind turbines have short ...
