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

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

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 ...

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 ...

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

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
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
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 ...
