In this review contribution we discuss the use of sulfonic acid-functionalized task-specific ionic liquids as sustainable and reusable catalysts for multicomponent reactions applied to the synthesis of heterocycles and related compounds.

The solvents derived from renewable raw materials can be used as an alternative green media for palladium-catalyzed carbonylation reactions, offering a promising and alternative way to construct a wide array of organic molecules carrying a carbon-oxygen double bond.

This review intends to show how the challenges for the production of some low molecular weight drugs produced by synthetic routes that involve at least one biotechnological step using microorganisms or enzymes were faced.

Internet of things (IoT) can play key role to attend the sustainable development goals. The association of IoT with analytical chemistry enables the real-time analytes monitoring, that assess impacts of human activities on environmental and human health.

A green analytical method using polyurethane foam and methylene blue was developed for the extraction and determination of lauryl ether sulfate in personal care hygiene products employing spectrophotometric and digital image detections.

The passion fruit seed ethanol extract presents a plethora of bioactive compounds, consistently reduced the viral load of the two Zika virus (ZIKV) strains (MR766 and PE243) and cellular NS1 expression of trophoblastic cells.

Geranyl acetate was synthesized using acetic acid, in the presence of enzymes and using different solvents and reactor types.

SnO₂ nanoparticles are activated by the high-energy ball milling process and enhance their photocatalytic activity to degrade rhodamine B.

Mining encoding sesquiterpene synthase genes in Streptomyces CBMAI 2042 reveals versatile enzymes promoting cyclization in terpenes biosynthesis.

The photoelectrodeposition of oxy-hydroxide-phosphates based on Co, Fe, or Ni was performed on WO₃/BiVO₄ heterojunction to produce photoanodes more efficient to the water oxidation under solar simulate light. The best catalyst increased 2.83 times the photocurrent compared to the non-modified heterojunction.

Additively-manufactured carbon-black-integrated polylactic acid sensor for antioxidant sensing: application to pyrogallol detection in biodiesel.

The correlation between the concentrations of the precursors used in the polymer synthesis that will be aged considerably affects the aging path that this sample will undergo. The electrochemical aging of the polymer is caused by the deactivation of parts of the polymer chain that are no longer able to intercalate ions and undergo oxidation/reduction.

The microwave synthesis of hesperidin-Mg improves yield. It can be used for Bemisia tabaci and Spodoptera frugiperda management strategy, and for Myzus persicae as repellent.

Hypochlorite in bleaching solutions was determined based on the temperature rise from the reaction with a hydrogen peroxide solution. Infrared thermal imaging was used for simultaneous contactless temperature measurements of multiple reactions in a microplate.

A simple method for persistent organic pollutants (POPs) and current-use pesticides (CUPs) determination in breast milk using gas chromatography coupled to mass spectrometry with negative chemical ionization (GC-NCI-MS) was successfully validated and applied to a biomonitoring study.
