Current research reviews the latest applications and discusses present capabilities while forecasting future trends, such as the development of advanced sorptive materials and integration with innovative analytical platforms, paving the way for more sustainable and efficient environmental monitoring solutions.

Mesoporous carbon-based materials from biomass can be produced through various synthetic methods and have diverse environmental applications.

An analysis of the relationship between fatty acids, chlorophyll, and RGB (red, blue, green) channels to identify the adulteration of extra virgin olive oil with soybean oil.

Novel functionalized microspheres with trimercaptotriazine (TMT) groups based on poly(styrene-co-divinylbenzene) (PS-DVB), with and without polystyrene brushes, were synthesized, characterized, and compared for TMT group content. The surface-initiated atom transfer radical polymerization (SI-ATRP) efficiency was compared under different surface initiations.

Exploring the native fruits of Brazil, cagaita and mamacadela, to uncover their potential for diverse applications.

A chemical feature-based pharmacophore model for cyclooxygenase-1 (COX-1) was developed to virtually screen nine commercial databases, yielding 807 potential hits. Following molecular docking, compounds with binding affinities between ‒11.27 and
‒10.47 kcal mol^-1 were identified, and four were selected for further analysis through molecular dynamics (MD) simulations, indicating their potential as lead compounds to modulate COX-1 activity in neuroinflammation.

Silver-dichloroquinoline complexes have been prepared and their spectroscopic, structural and mycobactericidal properties against Mycobacterium tuberculosis H37Rv (ATCC 27294) have been determined.

A model molecule tetradecanoic (myristic) acid was pyrolyzed under inert atmosphere in the presence of fresh and equilibrium Fluidized Catalytic Cracking (FCC) catalysts, containing two different levels of rare earth. Deoxygenated molecules were produced, potential precursors for green gasoline, kerosene and diesel production.

Benzimidazole derivatives were identified as potential cruzain (Cz) inhibitors through molecular modelling.

Electrospun polyvinyl alcohol (PVA) nanofibrous mats with poly(amidoamine) (PAMAM) dendrimers and ibuprofen were developed and characterized. The nanofibrous mats demonstrated controlled drug release, which indicates their potential for advanced drug delivery applications.
