Intensification of Alkaline Electrolyzer with Improved Two‑Phase Flow

open access: yesAdvanced Energy Materials, EarlyView.
Porous nickel‐type electrodes with low tortuosity are fabricated and their role in reducing the capillary pressure, bubble point, and ohmic resistance, which led to lower energy loss and higher current densities and efficiencies is investigated. The cell delivers a current density of 2 A cm−2 at ≈2 V.

Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.

A “Cool” Route to Battery Electrode Material Recovery

open access: yesAdvanced Energy Materials, EarlyView.
Ice‐stripping, a novel sub‐zero electrode delamination technique, enables >90% recovery of the electrode materials from manufacturing scrap and end‐of‐life batteries. Water is sprayed upon a porous electrode and quickly freezes when placed on a cold surface. The foil is peeled away, leaving behind the black mass with the morphology retained.

Stringency and dissimilarity of Maximum Residue Levels affect bilateral agri‐food trade stability

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Food standards are rising in both prevalence and stringency. They protect consumers and may enhance demand stability but also pose compliance challenges to producers, with ambiguous effects on the stability of trade relationships. We analyze the impact of importers' Maximum Residue Levels (MRLs) along with bilateral MRL dissimilarity between ...

Using satellite imagery to monitor remote rural economies at high frequency [PDF]

open access: yesarXiv
Despite global progress in reducing extreme poverty, stubborn pockets remain, often in remote and fragile regions. A fundamental obstacle to further progress is that remoteness and fragility also constrain our ability to monitor economic conditions.

Are veterinary drug maximum residue limits protectionist? International evidence

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract We analyze the distribution of maximum residue limits (MRLs) on veterinary drugs used in animal production and aquaculture in a global context of food consumption and trade. We compare MRLs by drug‐product pairs for a large set of countries, commodities, and drugs.

Governance Structure, Perception, and Innovation in Credence Food Transactions: The Role of Food Community Networks

open access: yesInternational Journal on Food System Dynamics, 2010
 Promoting transactions of more sustainable-oriented foods can be (socially and privately) complex and costly. New institutional economics (NIE) explains these dynamics by analyzing the choice of the "most cost-economizing" governance structure to ...
