This study investigated the feasibility of H₂ production by acid corrosion, employing a by-product from the fertilizer industry (Hexafluorsilic acid - H₂SiF₆) and waste iron sources. The influence of the variables was evaluated by factorial design, verifying greater production of H₂ for materials with higher contact areas.

We investigated the correlation between COVID-19 and environmental parameters in central South America. Fire radiative power (FRP) influence the daily cases COVID-19. The relative humidity of the air, (U%), mitigated the COVID-19.

Electrospun matrices generated from electrospinning technique. These were incorporated with propolis for utilization in wound dressing.

The intensity parameters were calculated using absorption and emission spectra of the Sm(III) or Eu(III) beta-diketone complexes, respectively. Highlyintense luminescence from lanthanides compounds enables us to identify the correlationbetween symmetry environment and spectroscopic properties.

A series of 1,2,3-triazoles inspired on the SRPIN340 was synthesized and had their effects evaluated on human glioblastoma multiform cell line U87MG.

This paper describes the structure, mechanism of action, synthetic routes, among other parameters related to drugs intended to treat the main diseases in Brazil.

Levulinic acid is a potential building block for biorefineries to add value to biomass and reduce dependence on the world oil economy.

This paper examines the recent advances in the design materials for biomedical applications prepared via electrospinning, solution blow spinning, film preparation methods, and 3D printing techniques.

The proposed method may be used both in health surveillance and monitoring and in quality control of food supplements, especially concerning the confirmation of caffeine content, which must be shown on the labels of products available on the market.

Commercially available water beads made of superabsorbent sodium polyacrylate can be a simple and inexpensive sorbent for iron concentration before colorimetric assay using digital images.

In this technical note, an impedimetric sensor was built from low-cost materials, to monitor online a reduction reaction of an organic contaminant (4-nitrophenol) to a value-added product (4-amino-phenol).

Teacher education in non-formal educational setting: The Scientific and Cultural Dissemination Center case.

Teaching of chemistry in context and based on modeling favors the construction and reconstruction of student explanatory models.

The water molecule should be placed on the yz plane, but a survey in the literature shows that this recommendation, made by Mulliken in 1955, is not followed in many textbooks and articles. This affects the label of the asymmetric vibration and of the HOMO as B₁ or B₂.

Should I label this approach I’m following? Should I call it metabolomics to match others? But I’ve just paid more attention to on the statistics.

An example of replacing an old laboratory procedure (heterogeneous generation of H₂S) by a current one (homogeneous generation of H₂S).
