Abstract
3D-printing technology has revolutionized electrochemical applications by enabling rapid prototyping of various devices with high precision, even in highly complex structures. However, a significant challenge remains in developing less costly and more sustainable analytical approaches and methods aimed at mitigating the negative environmental impacts of chemical analysis procedures. In this study, we propose a solution to these challenges by creating a simple and versatile electrochemical system that combines 3D-printing technology with recyclable disposable materials, such as graphite from an exhausted battery and a stainless-steel screw. Our results demonstrate a novel strategy for developing electrodes and other laboratory-made devices that align with the principles of sustainability and green chemistry. Furthermore, we provide evidence of the effectiveness of the proposed system in an analytical application involving the simultaneous determination of tert-butylhydroquinone, acetaminophen, and levofloxacin using the voltammetric technique in lake and groundwater samples. The results indicate sufficient accuracy, with recovery values ranging from 91 to 110%. Additionally, we utilized the Analytical GREEnness calculator as a metric system to evaluate the environmental friendliness of the proposed electroanalytical protocol. The final score confirms a favorable level of sustainability, reaffirming the eco-friendly nature of our approach.

Abstract
The present work reports the theoretical investigation of Co(II), Ni(II), and Zn(II) complexes containing Schiff bases (used as ligands) derived from the reaction of 2-hydroxy-1-naphthaldehyde with N-(2-aminoethyl) pyrazoles. The spectral analyses were carried out using infrared, Raman, and UV-Vis spectroscopy. Vibrational analyses were performed in order to investigate the mechanisms involving metal-ligand and intra-ligand vibrations and indicated the possibility of charge transfer related to the transitions n[Formula: see text]* and [Formula: see text]*. Structure optimizations and normal coordinate force field calculations were performed via the density functional theory (DFT) method at the HSE06/6-311G(d,p)/LanL2DZ level. A thorough analysis was also conducted regarding the nonlinear optical (NLO) properties and the natural bond orbital (NBO) of the complexes. The results show that these complexes have prospective application as materials for NLO. Furthermore, the NBO analysis confirms the coordination between the lone pair (LP) electrons of the donor atoms (O and N) and the metal acceptors. Finally, studies were conducted regarding the electronic properties of the complexes; among the properties investigated included the frontier molecular orbitals (FMO) and the molecular electrostatic potential (MEP), allowing to determine the energy gap and charge distribution.

Abstract
Os radicais livres são espécies altamente reativas geradas nos organismos vivos com a finalidade de proteção. Porém, em algumas circunstâncias, estes são responsáveis pela ocorrência ou o agravo de danos teciduais. Muitos antiinflamatórios apresentam ação direta sobre radicais livres e espécies reativas não radicalares, o que contribui para suas ações contra a inflamação. O cetoprofeno é um antiinflamatório não esteroidal que gera radicais livres ao sofrer fotoirradiação e tem com isso um efeito hemolítico importante. A complexação de metais a diferentes fármacos tem sido utilizada como estratégia para melhorar a ação farmacológica de diferentes moléculas e reduzir seus efeitos colaterais. Neste trabalho são apresentados resultados do estudo de ação do cetoprofeno e seus complexos de cério e cobre sobre radicais livres e sobre eritrócitos. Observou-se que o cério intensifica as propriedades scavenger do cetoprofeno sobre radicais livres enquanto o cobre intensifica as ações sobre oxidantes não radicalares. O cobre ainda reduziu o efeito hemolítico apresentado pelo cetoprofeno e mantido pelo seu derivado de cério.
