Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

Advanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Giving HOPE and minimising trauma: An intervention to support women who are separated from their babies at birth due to safeguarding concerns

Child Abuse Review, Volume 32, Issue 1, January/February 2023., 2023
Abstract Whatever the circumstances, the separation of infants from their mothers at birth is a traumatic experience for all concerned. The paper reports on a study designed to improve practice in this highly sensitive area. An analysis of data collected through semi‐structured interviews with 38 mothers who had experienced removal at birth identified ...

Predicting the Yields of z > 6.5 Quasar Surveys in the Era of Roman and Rubin

The Astrophysical Journal, 2023
About 70 luminous quasars discovered at z > 6.5 are strongly biased toward the bright end, thus not providing a comprehensive view of quasar abundance beyond the cosmic dawn. We present the predicted results of the Roman/Rubin high-redshift quasar survey,

Microstructure of Lithium Metal Electrodeposited at the Steel|Li6PS5Cl Interface in “Anode‐Free” Solid‐State Batteries

Advanced Energy Materials, EarlyView.
Reservoir‐free cells do not use lithium metal during cell preparation. Instead, lithium is electrodeposited during the initial charging step, potentially simplifying the manufacturing of solid‐state batteries. The electrochemical properties of the electrodeposited lithium layer are governed by its morphology and microstructure. However, little is known

Understanding Key NaCMC Properties to Optimize Electrodes and Battery Performance

Advanced Energy and Sustainability Research, EarlyView.
Sodium carboxymethyl cellulose (NaCMC) polymer properties, namely, the degree of substitution, molecular weight, and an in batteries unpublished impurity, are investigated with regard to their impact on the electrode properties. The gained knowledge then is transferred to further understand the resulting cell performance and understand key figures to ...

The Relationship Between Interest Rates and Agricultural Commodity Price Dynamics

Agribusiness, EarlyView.
ABSTRACT The U.S. Federal Reserve has undertaken several interest rate interventions in the past decade. This study explores the relationship between U.S. corn and soybean prices and Federal Reserve monetary policy interventions, in the short and long run.

An independent test of the photometric selection of white dwarf candidates using LAMOST DR3 [PDF]

, 2015
In Gentile Fusillo et al. (2015) we developed a selection method for white dwarf candidates which makes use of photometry, colours and proper motions to calculate a probability of being a white dwarf (Pwd). The application of our method to the Sloan Digital Sky Survey (SDSS) data release 10 resulted in nearly 66,000 photometrically selected objects ...
