Monetary Perspective On Underground Economic Activity In The United States [PDF]

, 2007
There are widespread reports of a growing underground, or unobserved, economy in the United States and in other countries. The unobserved economy seems to develop principally from efforts to evade taxes and government regulation.

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

Advanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion

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

Advanced 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.

Understanding Structural and Compositional Evolution during NMC Cathode Direct Recycling via Solid‐State NMR

Advanced Energy Materials, EarlyView.
Direct recycling end‐of‐life lithium‐ion batteries (LIB) to recover high‐value cathode materials such as LiNixMnyCozO2 (NMC) requires method development and detailed characterization. In this work, the unique capabilities of solid‐state NMR in characterizing changes in local ordering within NMC cathode materials during recycling and upcycling as well ...

Changing politics, economics and relations on the small remote island of Fair Isle [PDF]

Island Studies Journal, 2016
The paper interprets changes which have taken place on Fair Isle, a small remote Scottish island, over the last half century, with a focus on how the interplay of external forces and local adjustments have produced a positive working relationship between

Battery‐Grade Lithium Materials: Virgin Production and Recycling, a Techno‐Economic Comparison

Advanced Energy Materials, EarlyView.
With this study a framework has been created to analyze new innovative lithium compound manufacturing processes for their cost and environmental competitiveness. This analysis includes details on virgin and recycled pathways to produce lithium carbonate or lithium hydroxide monohydrate.

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

Applied 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.
