Extracts from the Amazon fruit piquiá (Caryocar villosum) were analyzed by HPLC-DAD, gallic and ellagic acids were detected and quantified. Cytotoxicity, antioxidant and anti-inflammatory activities were also studied.

Quantum-chemical simulations of 1,2,3-Trioxolene which is an intermediate in the acetylene ozonolysis reaction showed that, five member ring of the molecule is unstable in its C_2v high-symmetry planar configuration and it is folded along b₁ nuclear displacement to C_s symmetry equilibrium geometry.

Retorted oil shale has several trace elements in their composition and these can undergo different processes in the soil: leaching, sorption/desorption, precipitation/solubilization, according to local conditions.

Outline of the research studies to produce PEG-monooleate.

In this study, the electrophilic power and nucleophilic power were proposed as global descriptors for chemical reactivity.

Biological hydrogen production by anaerobic co-fermentation of organic waste and glycerol is an interesting alternative for clean fuel production.

Production of ethyl biodiesel by transesterification of soybean oil and ethanol catalyzed by using metal oxides derivatives from like-hydrotalcites materials modified with Ga³⁺

The fusel oil consisting primarily of isopentanol (> 60 %), a byproduct generated in the ethanol production, can be served as an alcohol source to yield flavor esters using different organic acids. The concept of a natural ester made by enzymatic synthesis with lipase and natural substrate components is an alternative to conventional organic synthesis route.

In this work is described an inventory of the main lines of health care wastewater at the Hospital of the Federal University of Paraná (HC/UFPR) and it is proposed a viable wastewater treatment.

Pectin extraction of melon is an alternative to increase the profits of producers by having more specific application, adding value to the fruit.

H₂ generation using photocatalysis by irradiation of semiconductor. Photolysis of water without the use of an external potential is known as Water Splitting.

Different cellular pathways in the Mycobacterium tuberculosis with potential molecular targets useful for drug discovery and development.

Chromatogram of thermal degradation of carbaryl in 1-naphthol when exposed to high temperature conditions and response surface plot for extraction of carbaryl.

A practical class was proposed using gold nanorods synthesized with CTAB and functionalized with specific antibodies. The target detection was performed by analysis of the surface plasmon resonance in UV-Vis-NIR spectrophotometer.
