Pt‐Based Electrocatalysts for Oxygen Reduction Reaction: Core–Shell Architectures and High‐Entropy Alloy Nanoparticles

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Illustrations of diverse nanoparticle architectures including core‐shells and advanced high‐entropy alloys (HEAs) as model electrocatalysts. These geometric configurations highlight the tunability of elemental distribution and structural complexity for enhanced ORR catalytic performances.

Sulfonated Diels–Alder Poly(Phenylene)s in Membrane Electrode Assemblies for Fuel Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study reveals that ionomer adsorption is the key performance‐limiting factor for sulfonated Diels–Alder poly(phenylene)s in fuel cell cathodes, with interfacial incompatibility and hydrophilicity also contributing. High performance is retained in membranes and anodes, but significant losses occur when used as cathode binders.

Challenges and Opportunities in Combining Ultrasound and Inductive Coupling for Energy Supply and Bidirectional Data Exchange in Bioelectronics Medicine Implant Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
In this contribution, it is shown that miniaturized nerve stimulation implants can be used in collaborative networks. Inductive links and ultrasound are combined to supply these implants with energy and data; the advantages and disadvantages of each method, as well as safety risks and possibilities for improvement are discussed and the best ...

Exploring the link between the risk of violent injury in adolescents and historic redlining practices

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Violent injuries tend to cluster together geospatially. The discriminatory housing practice of redlining undertaken by the United States federal government in the 1930s has been repeatedly linked with various contemporary community‐level disparities.

Exonic Variation and Its Clinical Impact in 7221 Old Order Amish

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Amish of Lancaster County, PA has been the focus of genetic studies for many years due to its demographic history and unique genetic makeup that includes a historical bottleneck event and subsequent genetic drift, resulting in a marked decrease in genetic diversity and increased frequency of some variants that have substantially shaped the
