Sewage sludge and wheat straw were synergistically converted via hydrothermal carbonization. The optimal condition (200 °C, 2:1 ratio) yielded hydrochar with superior combustion performance.

This study reports the synthesis and biological evaluation of a series of 2-(quinolin-4-yloxy) acetamides as antitubercular agents. The work highlights the structure-activity relationships, cytotoxicity, and aqueous solubility of the most active derivatives, identifying compound 6o as a valuable scaffold for future medicinal chemistry efforts.

A new recycling route for polyethylene terephthalate (PET) waste was developed through its partial depolymerization with glycerol, yielding a material with potential adsorbent properties.

Secondary metabolites from species of the Spondias genus were evaluated as potential inhibitors of monoamine oxidase A (MAO-A) through molecular docking studies and in vitro assays. The results revealed high binding affinity and enzyme inhibition, suggesting promising candidates for the treatment of depression.

Natural organic residues enriched with Ca and Mg for application in lettuce grown in water depths demonstrated positive results in crop growth and development.

OncoTherad (MRB-CFI-1), a novel nanoimmunotherapy developed in Brazil, activates innate immune system toll like receptors pathways to enhance antitumor immunity. This cost-effective innovation exemplifies scalable immunotherapy from the Global South.

The physical and chemical stability of emulsions containing a piceatannol-rich extract from passion fruit seeds, a spilanthol-rich extract from paracress, and UV filters was assessed by UV-Vis, analytical centrifugation, thermal analyses, and exposure to temperature cycles.

Binding of ligands to the Chromobox 4 (CBX4) protein to prevent potential oxidative stress and noise-induced deafness.

Laser-induced breakdown spectroscopy (LIBS) and hyperspectral imaging enable real-time monitoring and control of metal leaching from e-waste, supporting efficient and sustainable resource recovery.

The polydimethylsiloxane/polyvinylidene fluoride (PDMS/PVDF) membrane had the best hydrophobicity (145.2°), and the separation efficiency could still reach 95.0% after 20 cycles.

In general, in the upper Doce River, the concentration of As, Cr, Cu, Fe, Mn, Ni, and Pb exceeds the maximum limits of the Brazilian Resolution in the rainy season.

Malt bagasse residue is converted by sustainable method into P-doped hydrochar and applied as support of Co-Ni nanocatalysts for H₂ evolution.

Melaleuca alternifolia essential oil nanoemulsion was developed for pharma cosmetic applications, with a detailed analysis of its components, thermal stability evaluation, and droplet size characterization.

Binding mode of compound 16d (potential inhibitor) in the active site of the dissimilatory adenosine 5'-phosphosulfate reductase (APSrAB).

Simulated UV-Vis absorption spectrum of probe and sulfite adduct based on PBE0/def2TZVPD method.

The figure presents the methodological flow of the study of the volatile chemical constituents of Myrciaria tenella. The botanical identification of the species was performed, followed by the extraction of volatile compounds by hydrodistillation. The samples were analyzed by gas chromatography coupled with mass spectrometry to identify (E)-caryophyllene, δ-cadinene, α-calacorene, caryophyllene oxide, and 1-epi-cubenol. Finally, the data obtained were subjected to multivariate statistical analyses.
