2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

open access: yesChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found

Monitoring of Chlorinated Hydrocarbon Pollution of Meat and Fish in Croatia

open access: yesFood Technology and Biotechnology, 2002
Four hundred and sixty-six fatty tissue samples of beef, pork, poultry and fish were assayed by the gas and liquid chromatography between 1992 and 1996 for chlorinated hydrocarbons: hexachlorobenzene (HCB), α-hexachlorocyclohexane (α-HCH), γ ...

Who gets redeployed? Inventor characteristics and resource redeployment decisions

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary While the literature highlights the benefits of internally redeploying resources, there is less empirical guidance on which resources are most likely to be redeployed. We examine the relationship between inventor characteristics and redeployment decisions, motivated by the tension between costs and benefits of keeping a ...

Seeking for ultrashort "non-bonded" hydrogen-hydrogen contacts in some rigid hydrocarbons and their chlorinated derivatives

open access: yes, 2014
In this communication a systematic computational survey on some rigid hydrocarbon skeletons, e.g. half-cage pentacyclododecanes and tetracyclododecanes, and their chlorinated derivatives in order to seek for the so-called ultrashort "non-bonded" hydrogen-

Implementation of Policy Instruments for Chlorinated Solvents: A Comparison of Design Standards, Bans, and Taxes to Phase Out Trichloroethylene [PDF]

open access: yes
This paper studies the Swedish prohibition of the hazardous solvent Trichloroethylene (TCE). Sweden is alone in completely prohibiting its use. The ban has been at best a partial success and illustrates the dilemmas of policymaking.

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.
