Approaching the Monolayer Limit of Carbon Layers by Pyrolysis of Polymer Films
Advanced Electronic Materials, EarlyView.Wafer‐scale functional devices based on pyrolyzed photoresist films are synthesized directly on target substrates without catalysts or transfer steps, with channels reaching the monolayer limit (0.34 nm). X‐ray photoelectron spectroscopy confirms predominant sp2 character, Raman spectroscopy reveals evolving nanocrystallinity, and transmission electron

Statistics of the electromagnetic response of a chaotic reverberation chamber
Advanced Electromagnetics, 2015 This article presents a study of the electromagnetic re- sponse of a chaotic reverberation chamber (RC) in the pres- ence of losses. By means of simulations and of experi- ments, the fluctuations in the maxima of the field obtained in a conventional mode-

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 ...

Assessing Agricultural Green Total Factor Productivity in Latin America
Agribusiness, EarlyView.ABSTRACT The agricultural sector in Latin America plays a vital role in ensuring food security while impacting the environment. However, there remains a lack of analysis regarding the inputs responsible for pollution within its sub‐technologies. Hence, this article aims to assess agricultural green total factor productivity (TFP) through a novel ...

Australian Journal of Social Issues, EarlyView.ABSTRACT This paper applies Critical Race Theory (CRT) to explore how whiteness operates within Australia's anti‐racism movement as a structuring force that shapes discourse, practice and policy. Despite the anti‐racism movement offering crucial spaces for resistance and reform, it remains entangled in Australia's settler‐colonial present and systemic ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study examined the degradation of Reactive Red 180 and safranin using zinc oxide photocatalysis. Complete dye removal was achieved for both dyes under optimal conditions within 2 h. For Reactive Red 180, the optimum conditions were pH 10, 0.5 g/L zinc oxide, 25 ppm dye concentration, and 1 L volume. For safranin, the conditions were pH 10,
