The occurrence of antibiotics in the Brazilian aqueous matrix was carefully revised. The publication of 24 articles on this occurrence revealed the detection of 23 antibiotics in 5 aquatic matrices, ranging from 0.13 to 37300 ng L⁻¹.

Predicted structure of alpha-glucosidase of Candida albicans and structural superimposition of predicted structure.

Computational approach to study NS2B-NS3 protease from Zika Virus (ZIKV) enzyme complex as a target of natural compounds inhibitors such as myricetin, quercetin, luteolin, isorhamnetin, apigenin and curcumin from edible plants.

Cold-pressed coffee oil extraction was studied and optimized. This is the first description of serotonin amides in this material. Fatty acids (as methyl esters (FAME)) and ent-kaurane diterpenes were also analyzed.

How the morphology of the catalytic support influences the performance of nickel catalysts in the dry reforming reaction of methane.

Bioactive and antimicrobial materials were produced by coating highly porous TiO₂ surfaces with silver nanoparticles (AgNp) and poly(lactic acid) (PLA). The materials presented antimicrobial activity against Staphylococcus aureus and good biocompatibility in mouse MC3T3-E1 pre-osteoblasts tests.

Novel fatty acid aryl amides offer potential protection for strawberry crops against three significant insect species, without defensive registered products in Brazil.

This study measured the presence and risk assessment of three non-steroidal anti-inflammatory drugs (mefenamic acid, diclofenac, and naproxen) in river waters.

A strategic combination of polymeric ligands and folate with plasmonic nanoparticles for a multifunctional platform.

Extraction conditions for the polysaccharide from Inga edulis were determined using Taguchi model design (pH 2.4, 1 h and 90 °C). After characterization, the polysaccharide was applied in oil-in-water emulsion and the lower concentration of polysaccharide provided the best emulsifying capability and stability.

Heavy metals are bioaccumulative and can be removed using xanthates through complexation. Therefore, this theoretical study evaluated the structural and thermochemical behaviors of cadmium(II) and mercury(II) complexes with aqua and xanthate ligands.

The electronic structure and supramolecular arrangement of quinoline-chalcones were investigated and it was observed to have potential pesticidal against Agrobacterium tumefaciens and Bemisia tabaci.

This work is the first to use the construction of synthetic samples for analysis of coffees, and its objective is to identify adulterations in specialty coffees with bark, straw and low-quality beans, using UV-Vis spectroscopy associated with chemometric methods.

River water samples were collected and extracted using solid phase extraction. After this step, the analytes of interest were eluted for analysis.

This study explores the production of bioactive peptides and amino acids through hydrolysis of brewing yeast waste, resulting in a biologically functional protein hydrolysate.

Development and validation of an analytical method by high-performance liquid chromatography for the simultaneous quantification of gallic acid, catechin, and epicatechin, in leaf extracts from Campomanesia adamantium and evaluation of seasonal chemical variability.

The UV irradiation causes the generation of reactive oxygen species (ROS) in the skin, which in turn, mediates oxidative damage but photoaging can be mitigated using plants with antioxidant capacity. Guazuma extracts capture free radicals, aid healing, restore enzymes and protect cells against UV-A.
