Fluorinated copolymer resists for high‐resolution negative‐tone lithography: Preparation and patterning performance

open access: yesSmart Molecules, EarlyView.
Electron‐beam induced C–F cleavage in –CF3 generates F−, which abstracts a proton to form the acid that catalyzes tBMA deprotection during post‐exposure baking. This self‐sensitization mechanism enables the precise formation of high‐resolution negative‐tone patterns with enhanced sensitivity and resolution.

Scalable Room‐Temperature Terahertz Graphene Cameras

open access: yesSmall Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Evaluation of illicit drug contaminants in seized cannabis in Arizona and California, 2023–2024

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Despite public health concerns, fentanyl, cocaine, and other illicit drug contaminants remain largely understudied in unregulated cannabis. Here, we developed an analytical method to quantify a panel of common illicit drugs in cannabis and tested the law enforcement seizures in Arizona and California in evaluation of the illicit drug ...

From Conflicting Outcomes to Mutual Losses: How Punitive Responses to Problematic Substance Use Suppress Help‐Seeking and Cause Harm

open access: yesHuman Resource Management Journal, EarlyView.
ABSTRACT Problematic substance use (PSU) is a significant, inadequately managed people management challenge. Drawing on the conflicting outcomes and mutual losses perspectives on HRM and employee wellbeing, and using Job Demands‐Resources theory to explain underlying strain‐driven loss cycles, we examine factors shaping PSU and help‐seeking among 575 ...

The estrous cycle has no effect on incubation of methamphetamine craving and associated Fos expression in dorsomedial striatum and anterior intralaminar nucleus of thalamus

open access: yesAddiction Neuroscience
Relapse is a major challenge in treating drug addiction, and drug seeking progressively increases after abstinence, a phenomenon termed “incubation of drug craving”.

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

open access: yesAddiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

Protective Effect of Sauchinone on Methamphetamine-Induced Neurotoxicity in Mice

open access: yesJournal of Pharmacological Sciences, 2012
Sauchinone is a lignan isolated from Saururus chinensis known to suppress nitric oxide (NO) activity. Previous studies demonstrate that NO plays a key role in methamphetamine-induced neurotoxicity.
