Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

open access: yesAdvanced Electronic Materials, EarlyView.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

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.

Pretreatment and Valorization of Critical Materials from Lithium‐Ion Batteries Using Electrostatic and Magnetic Separation

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study investigates how magnetic and electrostatic separation processes can be applied to coarsely shredded Li‐ion batteries to effectively recover high‐purity concentrates of shredded cathode electrode, shredded anode electrode, and shredded separator.
