The Predictive Validity of Marijuana Odor Detection: An Examination of Alaska State Trooper Case Reports 2006–2010 [PDF]

open access: yes, 2012
This study provides an empirical estimate of the extent to which Alaska State Troopers (AST) investigators’ detection of marijuana odors served as a reliable indicator of the presence of illegal quantities of marijuana in suspected structures/buildings ...

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Understanding the relationship between acid precipitation and lignin odor in Kraft Black liquor

open access: yesCleaner Chemical Engineering
Kraft black liquor, utilized as a lignin feedstock, is increasingly acknowledged as a valuable resource for the production of high-value products. Acid precipitation has proved to be one prominent method for separating this lignin, but its impact on ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Analysis of Key Flavor Compounds in Dairy Fat Products Using Relative Odor Activity Value and Olfactometry

open access: yesShipin Kexue, 2023
In this study, solid phase microextraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS) was used to investigate the volatile compound profiles of eight dairy fat products (including four butters, two creams and two cultured butters) that are popular on the Chinese market.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Willingness to Pay for Reducing Global and Local Air Pollution: Evidence from Terre Haute, Indiana [PDF]

open access: yes, 2019
This article examines results from a survey of Indiana State University (ISU) students on the level of concern and willingness to pay for improving the environment on local and global levels using the contingent valuation methodology. On the local level,

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation
