Tuning Antiaromaticity Through Meso‐Substituent Orientation in Core‐Modified Isophlorins

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The antiaromaticity of dithiadioxaisophlorins is controlled by the steric bulkiness of meso‐substituents through their tilt angle relative to the macrocycle. Bulkier substituents maintain larger angles, preserving stronger antiaromaticity, while smaller groups facilitate π‐conjugation with the macrocycle, diminishing antiaromaticity.

Production of Secondary Organic Aerosol During Aging of Biomass Burning Smoke From Fresh Fuels and Its Relationship to VOC Precursors [PDF]

open access: yes, 2019
After smoke from burning biomass is emitted into the atmosphere, chemical and physical processes change the composition and amount of organic aerosol present in the aged, diluted plume. During the fourth Fire Lab at Missoula Experiment, we performed smog-

Comparison of Predicted and Observed Dioxin Levels in Fish: Implications for Risk Assessment [PDF]

open access: yes, 1993
After comparing sampled and modelled dioxin levels in the tissue of fish near pulp and paper mill discharges, the authors argue that, until an improved bioaccumulation model is incorporated into EPA\u27s Risk assessment process, determination of human ...

Formation of furan and furan derivatives in baby food products

open access: yesFood Chemistry
A comprehensive analysis of 89 commercial baby food samples showed the highest levels of furan in ready-to-eat full meals and vegetable purees (12-118 μg/kg). The alkylated furans (2- and 3-methylfuran, 2-ethylfuran, 2-pentylfuran) were predominantly found in these baby food categories.

Interfacial Photoelectrochemistry in Organic Synthesis

open access: yesAngewandte Chemie International Edition, Accepted Article.
Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.
