Nanoscale Buried Interface Control in Silicone Hydrogels Enables a Biointerface Engineering Platform

open access: yesAdvanced Science, EarlyView.
A hydrophilic coating with controllable nanoscale thickness is applied to commercial silicone hydrogel contact lenses. By combining comprehensive multi‐modal three‐dimensional characterization with an advanced algorithm, the thickness and chemical information of these multilayered structures are resolved.

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

open access: yesAdvanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Single‐Cell Map of Early Lung Adenocarcinoma Uncovers Invasion‐Associated Tertiary Lymphoid Structures

open access: yesAdvanced Science, EarlyView.
Early thoracic lesions are already heavily infiltrated by immune cells, yet these infiltrates largely consist of bystander T lymphocytes within an immunosuppressive microenvironment. Pathological invasion is strikingly associated with the neogenesis of T/B cell‐rich TLSs that predominantly remain immature.

Reframing Porous Carbon as a Transport Framework for High‐Rate CO2 Electroreduction

open access: yesAdvanced Science, EarlyView.
Hierarchical integration of Cu nanodomains with porous carbon frameworks promotes reactant transport during high‐rate CO2 electroreduction. Compared with a physically mixed benchmark, the integrated architecture shortens effective transport paths, mitigates local CO2 depletion, and lowers cathodic overpotential, enabling higher ethylene Faradaic ...

Farmers' Preferences for Fossil‐Free Mineral Nitrogen Fertilizers: Role of Prices, Climate, Production Origin, and Identity

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Disruptions in global fertilizer markets and climate targets have increased interest in fossil‐free mineral nitrogen fertilizers. This study examines farmers' preferences for conventional (fossil‐based) and fossil‐free fertilizers using a labeled discrete choice experiment with 211 Swedish farmers.

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.
