Built‐In Electric Field Regulated Electron Transport Channels of FeP Supported Os for Ampere‐Level Seawater Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
This work presents an Os/FeP heterostructure catalyst with EMSI and successfully utilizes the BEF to further modulate electron transfer through Os‐P‐Fe channels, proving an effective approach of developing low‐cost electrocatalysts with remarkable HER activity in ampere‐level seawater electrolysis. ABSTRACT Developing cost‐effective and robust hydrogen

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The
