The Role of Cl- Ions During the Adsorption of Polyethylene Glycol (MW 20,000) onto a Polycrystalline Gold Electrode

open access: yesInternational Journal of Electrochemical Science, 2012
The adsorption of polyethylene glycol (MW 20,000) (PEG20000) onto a polycrystalline gold electrode in the presence of Cl- ions was studied by differential capacitance measurements and quartz crystal microbalance. This study provides new physical insights

Exploring the Antiparasitic Activity of the Sea Cucumber Isostichopus sp. aff. badionotus From the Northern Coast of Colombia Against Trypanosoma cruzi

open access: yesThe Scientific World Journal, Volume 2026, Issue 1, 2026.
Chagas disease, caused by Trypanosoma cruzi, remains a neglected tropical infection with limited therapeutic options. Sea cucumbers are recognized as rich sources of bioactive sulfated metabolites with potential antiparasitic properties; however, information on the chemistry and trypanocidal activity of Caribbean Isostichopus species is still scarce ...

Differentiating between F and OH Ligands in Homologous Gold(III) Complexes beyond X‐Ray Crystallography

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 34, December 1, 2025.
A subtle hydrogen‐bonding lock enables the unequivocal structural differentiation between fluoride and hydroxide in the unusual couple of homologous organogold(III) complexes [PPh4][(CF3)3AuF] and [PPh4][(CF3)3Au(OH)] (see adjacent figure). The homologous fluoride and hydroxide complexes of gold(III) [PPh4][(CF3)3AuX] [X = F (1), OH (2)] have been ...

Microbe‐induced resistance involves priming of direct or indirect defenses according to the stage of herbivory

open access: yesNew Phytologist, Volume 248, Issue 6, Page 3256-3269, December 2025.
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...
