Electrochemical characterization of mangrove sediments: A proposal of new proxies for organic matter oxidation
(Elsevier, 2019)
The voltammetric response of microparticulate deposits resulting from solvent evaporation of ethanolic extracts of mangrove sediments in contact with aqueous acetate buffer is hereby described. Dated sediment cores sampled ...
COD/DOC balanced models for the oxidation process of organic compounds
(Brazilian Society of Chemical Engineering, 2020-03)
Nowadays, several advanced oxidation and enzymatic processes are available for the removal of organic compounds. Mathematical models are crucial to optimize the operating conditions and to reduce the costs associated with ...
UV-absorbing compounds in Porphyra haitanensis (Rhodophyta) with special reference to effects of desiccation
(Springer, 2008-08)
The intertidal red alga Porphyra haitanensis Chang et Zheng is episodically desiccated and exposed to high levels of solar radiation at low tide during emersion. However, little has been documented on the relationship ...
Natural compounds as potential algaecides for waterborne paints
(Springer, 2018-09)
To eliminate and prevent the formation of phototrophic biofilms on painted walls, chemicals are added to paints. These chemicals, in general, also have toxic effects on the environment. Plants synthesize secondary metabolites ...
Asymmetric Organocatalytic C-C Bond Forming Reactions with Organoboron Compounds: A Mechanistic Survey
(Wiley VCH Verlag, 2019-05-26)
The recent development of asymmetric organocatalytic C-C bond forming reactions involving organoboranes has attracted big interest in the synthetic community. Asymmetric organocatalytic additions to enones, aldehydes, ...
Natural compounds as additives in paints for controlling algal growth
(Asia Pacific Coatings Journal, 2019-02)
Algae are a diverse group of photosynthetic organisms, ranging from microscopic single-cell micro-organisms to very large organisms, such as seaweed. Microalgae belonging to Chlorophyta (green algae) and Cyanophyta (blue-green ...
Plant‐based compounds with potential as push‐pull stimuli to manage behavior of leaf‐cutting ants
(2017-05)
Leaf‐cutting ants are a serious pest of young forestry plantations. Currently, the main control method is the use of broad‐spectrum insecticides, which have a negative effect on non‐target organisms and the environment. ...
