Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Dual‐Atom Catalyst Au@S‐rGO for Rapid and Highly Sensitive Electrochemical Detection of Fentanyl in Serum

open access: yesAdvanced Science, EarlyView.
This study develops an Au/S‐doped reduced graphene oxide (Au@S‐rGO) sensor for rapid fentanyl detection. DFT simulations and structural analysis confirm atomically dispersed Au/S configurations, enhancing catalytic activity. The sensor achieves a 9.7 nmol L−1 detection limit, 98–104% recovery in human serum, and 85.7–93.6% consistency with mass ...

Utilizing Caenorhabditis Elegans as a Rapid and Precise Model for Assessing Amphetamine‐Type Stimulants: A Novel Approach to Evaluating New Psychoactive Substances Activity and Mechanisms

open access: yesAdvanced Science, EarlyView.
This study uses Caenorhabditis elegans to assess the activity of amphetamine‐type stimulants (ATS) and their analogs. The research highlights the roles of dopamine and serotonin pathways, distinguishes chiral forms of ATS, and identifies structure‐activity relationships. These findings provide a rapid and cost‐effective model for evaluating the effects

US employment exposure to domestic and foreign tariff changes under NAFTA

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Literature examining the effects of changes in trade agreements and import competition on US employment and wages has focused primarily on non‐agricultural industries and changes in US import tariffs. We propose a method for measuring worker exposure to changes in agricultural tariffs using a newly developed county‐level dataset of employment ...

Improving Fairness in Criminal Justice Algorithmic Risk Assessments Using Conformal Prediction Sets [PDF]

open access: yesarXiv, 2020
Risk assessment algorithms have been correctly criticized for potential unfairness, and there is an active cottage industry trying to make repairs. In this paper, we adopt a framework from conformal prediction sets to remove unfairness from risk algorithms themselves and the covariates used for forecasting.
