ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

A Tri-Band Cooled Receiver for Geodetic VLBI
Sensors, 2021 This paper shows a simultaneous tri-band (S: 2.2–2.7 GHz, X: 7.5–9 GHz and Ka: 28–33 GHz) low-noise cryogenic receiver for geodetic Very Long Baseline Interferometry (geo-VLBI) which has been developed at Yebes Observatory laboratories in Spain.

Equine Veterinary Journal, EarlyView.Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...

Variability and uncertainty in measuring sea surface temperature
, 2012 Sea Surface Temperature (SST) measurement is one of the most easily obtainable climate variables. However, it is challenging to meet the required absolute accuracy and long term stability whether the data are derived by in situ or satellite measurements.

Irrigation and Drainage, EarlyView.ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Analysis of a microwave radiometer for precise standardization of noise sources
, 1963 Calibration of microwave noise sources requires a standard source, an attenuator, and an instrument for comparing microwave power levels. A modified Dicke radiometer is used for this comparison.
