A Low-Cost Sensing Strategy for Blade Tip Timing: An Inductive Proximity Probe Approach

Engineering Proceedings
Blade Tip Timing (BTT) provides a superior long-term blade monitoring solution compared to strain gauges, yet its adoption in lower value turbomachinery remains constrained by sensor costs.

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

Advanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

INVESTIGATION OF STALL FLUTTER OF FAN BLADES BY BLADE TIP-TIMING SYSTEM

Flutter is a system mode that all blades vibrate at thesame frequency but with a different phase angle, which canform a nodal diameter (ND) pattern. One of the advantagesof blade tip-timing (BTT) technique is to measure thevibrational displacements of all blades, which makes BTTa potential method to study flutter.

Separating Hydrogen Evolution From Electroplating in Zn Metal Batteries Using Scanning Electrochemical Microscopy

Advanced Energy Materials, EarlyView.
Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

Examining the relationship between wind turbine blade performance and tip vortex behaviour in the wake [PDF]

, 1997
This paper details the results of laboratory tests on a model wind turbine rotor at the University of Edinburgh and examines tip vortex behaviour which questions the assumptions of current rotor performance prediction codes.

Hybrid Ionomer‐Free Porous Transport Electrodes With Catalyst Coated Membranes for Enhanced Water Electrolysis

Advanced Energy Materials, EarlyView.
We demonstrate how improved electrochemical performance during water electrolysis is achieved when a porous transport electrode (PTE) is coupled with a traditional catalyst coated membrane (CCM). Using operando neutron radiography, a more homogenous water distribution near the catalyst layer‐membrane interface is revealed in PTE‐based designs due to ...
