Cylindrospermopsin (CYN) is a toxic secondary metabolite produced by several freshwater species of cyanobacteria. Its high chemical stability and wide biological activity pose a series of threats for human and animal morbidity and mortality. The biggest risk of CYN exposure for human organism comes from the consumption of contaminated water, fish or seafood. Very important for effective monitoring of the occurrence of CYN in aquatic environment is accurate identification of cyanobacteria species, that are potentially able to synthesize CYN. In this review we collect data about the discovery of CYN production in cyanobacteria and present the morphological changes between all its producers. Additionally we set together the results describing the catalytic decomposition of CYN.

Graphitic carbon nitride (g-CN) proved to be a promising semiconductor for the photocatalytic degradation of various organic pollutants. However, its efficacy is limited by a fast electron hole recombination, a restricted quantity of active sites, and a modest absorption in the visible range. To overcome these limitations, g-CN-BiS and g-CN-ZnS composites were effectively produced utilizing a starch-assisted technique.

Enhancing CO Adsorption on MgO: Insights into Dopant Selection and Mechanistic Pathways.

Biomimetics (Basel)

Inspired by our recent success in designing CO-phobic and CO-philic domains on nano-MgO for effective CO adsorption, our ongoing efforts focus on incorporating dopants into pristine MgO to further enhance its CO adsorption capabilities. However, a clear set of guidelines for dopant selection and a holistic understanding of the underlying mechanisms is still lacking. In our investigation, we combined first-principles calculations with experimental approaches to explore the crystal and electronic structural changes in MgO doped with high-valence elements (Al, C, Si, and Ti) and their interactions with CO.

Activated carbon textile (C-Text) was chemically modified to incorporate oxygen- (C-Text-O), nitrogen- (C-Text-ON), and/or sulfur- (C-Text-OS) containing surface functional groups, aiming to enhance their reactive adsorption capacity. The modified textiles were evaluated for their ability to detoxify 2-choloroethyl ethyl sulfide (CEES) in both vapor and liquid phases, under dry and humid conditions. The maximum amount of water adsorbed was directly affected by the surface area (R = 0.

Electron delocalization is studied in the ground singlet and first excited triplet states of azulene-containing helicenes. After showing that the compounds we study can be synthesized, we show that they exhibit a charge separation in the ground state, which does not appear in their triplet excited state. Then, magnetically induced properties (IMS3D and ACID) and electron density decomposition methods (EDDB) are used to rationalize aromaticity in these systems.
