A comparison of the analytical and experimental performance of the solid version of a cooled radial turbine [PDF]

open access: yes
An evaluation of the aerodynamic performance of the solid version of an Allison-designed cooled radial turbine was conducted at NASA Lewis' Warm Turbine Test Facility. The resulting pressure and temperature measurements are used to calculate vane, rotor,

Ion‐Regulating SPEEK–BNNS Hybrid Interfaces Enabling Low‐Barrier Zn‐Ion Transport and Dendrite‐Free Zinc Anodes

open access: yesSmall, EarlyView.
A scalable organic–inorganic hybrid protective layer composed of sulfonated poly(ether ether ketone) and boron nitride nanosheets is introduced to stabilize Zn‐metal anodes. The hybrid architecture regulates Zn2+ transport, suppresses dendrite growth, and mitigates parasitic reactions, enabling uniform Zn deposition and long‐term stable cycling in ...

Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

open access: yesHigh Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

Twin‐compartment solid–liquid cells for neutron reflectometry

open access: yesJournal of Applied Crystallography, EarlyView.
We introduce a twin‐compartment solid–liquid cell for neutron reflectometry that divides a single substrate into two independent measurement areas, doubling sample capacity and enabling direct side‐by‐side comparisons. This sample environment also reduces alignment and sample preparation time and has been successfully tested on both vertical and ...
