Is there a causal association between genotoxicity and the imposex effect? [PDF]

open access: yes, 2006
There is a growing body of evidence that indicates common environmental pollutants are capable of disrupting reproductive and developmental processes by interfering with the actions of endogenous hormones.

Methods for synthesizing diethyl carbonate from ethanol and supercritical carbon dioxide by one-pot or two-step reactions in the presence of potassium carbonate [PDF]

open access: yes, 2009
Carbon dioxide sequestration was studied by synthesizing diethyl carbonate (DEC) from ethanol and CO2 under supercritical conditions in the presence of potassium carbonate as a base. The co-reagent was ethyl iodide or a concentrated strong acid.

Surficial N+ Charge Density as Key Factor for Inhibition of Pseudomonas Biofilm Formation in Non‐Leaching Quaternary Ammonium‐Modified Polydimethylsiloxane Coatings

open access: yesChemistry – A European Journal, Volume 32, Issue 14, 15 April 2026.
Biological fouling threatens marine ecosystems and infrastructures, demanding sustainable solutions. We designed PDMS materials functionalized with quaternary ammonium‐based silanes that inhibit biofilm formation of a highly resilient Gram‐negative Pseudomonas strain.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Developmental toxicity of organotin compounds in animals

open access: yesFrontiers in Marine Science, 2014
Organotin compounds (OTs) have been used as biocides in antifouling paints and agriculture. The IMO introduced a global ban on the use of OTs in antifouling systems in 2001 due to their high toxicity.
