Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

open access: yesAdvanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

Peroxide‐Driven Nitrogen Fixation Reactions for Energy Storage Applications

open access: yesAdvanced Energy Materials, EarlyView.
Sustainable ammonia synthesis from air as a hydrogen energy carrier and storage medium is demonstrated via an efficient dual‐step electrochemical approach at ultralow overpotential (−0.1 V vs. RHE). Atmospheric nitrogen is first oxidized to nitrate using in situ generated peroxide, then directly converts to ammonia on the same electrode, achieving ...

Dynamic changes in the structure and concentration of the international grain and oilseed trading industry

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract This paper aims to describe the evolution of firm and industry strategies and to analyze detailed transaction data on the structure of the international grain trading industry. Specifically, data are developed from vessel nominations, and these were used to derive measures of concentration and determine how these change across selected ...

King and Cochrane: The technological treadmill and racial inequity in US agriculture

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.
