Advanced Science, EarlyView.This article demonstrates a vacuum direct current arc discharge strategy for synthesizing Pt single‐atom catalysts (SACs) with an ultra‐high Pt areal density. The resulting catalyst shows remarkable thermal stability at 1000 °C and excellent performance in water splitting.

Reverberation Chambers for Over-the-Air Tests: An Overview of Two Decades of Research
IEEE Access, 2018 The reverberation chamber (RC) has traditionally been used for electromagnetic compatibility tests. About two decade ago, it found application in various over-the-air (OTA) tests of antennas and wireless devices.

Do Consumers Value Diversity in Agriculture? A Choice Experiment
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Farm ownership in the US today is racially and ethnically homogeneous. Diverse farmers and ranchers make up less than 10% of all producers, they tend to be less financially stable and have tighter profit margins. In the past few years, both government and industry programs have aimed to increase the participation and profitability of diverse ...

Bulk and Surface Reactivity of LiNi0.5Mn1.5O4 in Contact with (Acidic) Water
Advanced Energy and Sustainability Research, EarlyView.The comprehensive investigation of the influence of (acidic) water on LiNi0.5Mn1.5O4 as cobalt‐free lithium‐ion battery cathode material reveals that such treatment particularly affects a very thin layer at the particle surface, while the bulk material remains unaffected.
