UiO-66-type Metal-Organic Frameworks (MOFs) were synthesized with functionalized organic linker. UiO-66-NH₂ has the highest CO₂ adsorption capacity.

The application of liquid swine waste doses to a clayey Cerrado Oxisol improved its physical, chemical, and electrochemical attributes, leading to an increase in nutrient availability for plants and clay aggregation.

Schiff bases (SB) are diverse organic compounds, holding potential in both chemistry and biology. We explored an amino benzoic acid SB that presents a stable intramolecular hydrogen bond by cyclic voltammetric profiles supported by computational protocol to estimate redox potentials.

This work deal with the phytochemical and dereplication studies, as well as antimicrobial and anticholinesterase evaluation of Palicourea tomentosa.

This paper describes a synthesis, and characterization of an organofunctionalized silica (Sil-TMSDT) and its application as a solid phase in the preconcentration (SPE) of Pt⁴⁺ ions in aqueous media, using detection by flame atomic absorption spectrometry (FAAS).

Bisphenol A (BPA) is challenging to remove in conventional wastewater treatment. In this study, with the laccase enzyme from Pleurotus ostreatus induced by acai berry and pineapple residues, BPA was effectively degraded within 4 hours.

Amburana acreana Ducke leaves afforded coumarin, p-hydroxybenzoic, vanillic acids, campesterol 3-β-D-glucoside and amburoside B.

A phytochemical study from aerial parts of Pavonia glazioviana Gurke led to identify fifteen compounds, with emphasis on the polymethoxylated flavonoids that showed antimicrobial activity.

The synthesis of the coordination complex between aceclofenac and lanthanum or gadolinium ions results in stable compounds with potential medical and catalytic applications. Thermoanalytical characterization reveals information about the structure and thermal stability, while thermokinetic analysis investigates reaction rates, decomposition, and phase transitions, contributing to an overall understanding of the thermal behavior of the complex.

In this paper, we describe the hydrothermal synthesis of Nb₂O₅ and their application in photodegradation of dyes (methylene blue (MB) and indigo carmine (IC)) and photoesterification of free fatty acids (FFA) which are present in waste cooking oil (WCO).

HBeta, USY, and HZSM-5 zeolites produce solketal from glycerol and 2,2-DMP with higher yield under mild conditions.

PSI-MS spectra of urine samples from control individuals and patients with prostate cancer used in multivariate calibration with orthogonal correction to develop the OPLS-DA model.

A portable near-infrared spectrometer (linear variable filter (LVF) used as a dispersive element) was applied to rapidly detect methamphetamine samples on site, and 359 methamphetamine crystal and 187 methamphetamine tablet samples were modeled and analyzed.

In this study, the influence of deaeration on the electrochemical behavior of aluminum was investigated using polarization techniques. The advantages of deaeration in assessing localized corrosion on aluminum are addressed.

Based on zeolitic imidazolate framework-8 (ZIF-8), Zn-Fe bimetallic ZIF was synthesized. Subsequently, the photocatalytic nitrogen fixation performance of the sample was investigated. The synthesis process of the samples is simple, and they exhibit excellent photocatalytic nitrogen fixation performance.

Corrosion rate comparison in millimeters per year between the cities of Cubatão, Praia Grande and São Paulo in the following cases: exposed without anode; exposed with anode; buried without anode; buried with anode.

This review provides an overview of recent advancements in organic electrosynthesis in Brazil. It highlights the principles, applications, and limitations of various electrosynthetic methodologies, aiming primarily to enhance the understanding of fundamental principles and stimulate research in this field.

The existence of mobile colloidal fractions favors the transport of pollutants through the soil, even when strongly sorbed.

Comparative splitting of spectroscopic terms for a p² electronic configuration following LS and jj spin-orbit coupling schemes.

Integrating the chemical, historical, physical, and mathematical concepts encompassed by crystallography in the determination of crystal structure through X-ray diffraction fosters a more comprehensive and effective grasp of this powerful interdisciplinary tool.
