  • Conformational preferences induced by cyclization in orbitides: a vibrational CD study 

    Yokomichi, Maria Augusta Saemi [UNIFESP]; Silva, Hanyeny R. L.; Brandao, Lorenza E. V. N.; Vicente, Eduardo Festozo; Batista Junior, João Marcos [UNIFESP] (Royal Society of Chemistry (RSC), 2022-01-18)
    Orbitides are bioactive head-to-tail natural cyclic peptides from plant species. Their bioactivity is intrinsically related to the main conformations adopted in solution, whose correct characterization represents an important ...
  • How Biomining has been Used to Recover Metals from Ores and Waste? A Review 

    Brandão, Igor Yannick das Neves Vasconcellos [UNIFESP]; Munakata, Atílio Akihiro [UNIFESP]; Lourenço, Luís Antonio; Maass, Danielle [UNIFESP] (Damir Bucković, 2021-11-18)
    The recovery of metals present in low-grade ores and waste of electrical and electronic equipment (WEEE) is essential for the development of new technologies and the supply of existing production chains. Conventional ...
  • Biosynthesis of iron oxide nanoparticles from mineral coal tailings in a stirred tank reactor 

    Maass, Danielle [UNIFESP]; Valério, Alexsandra; Lourenço, Luís Antonio; Oliveira, Débora de; Hotza, Dachamir (Gamini Senanayake, 2019-01-23)
    Chemical oxidation of mineral coal tailings is one of the most important environmental issues during the lifetime of a mine. The presence of sulfur compounds favors the occurrence of metal acid leaching, which contaminates ...
  • A low‑cost brewery waste as a carbon source in bio‑surfactant production 

    Corrêa Nazareth, Talita; Planas Zanutto, Conrado; Maass, Danielle [UNIFESP]; Ulson de Souza, Antônio Augusto; Guelli Ulson de Souza, Selene Maria de Arruda (Dirk Weuster-Botz, 2021-06-22)
    This work aims to produce bio-surfactant using a brewery waste (trub) as a strategy to reduce production costs related to the substrate, as well as to provide an eco-friendly destination for this residue. Trub is obtained ...
  • Bioconversion of low-cost brewery waste to biosurfactant: an improvement of surfactin production by culture medium optimization 

    Corrêa Nazareth, Talita; Planas Zanutto, Conrado; Maass, Danielle [UNIFESP]; Ulson de Souza, Antônio Augusto; Guelli Ulson de Souza, Selene Maria de Arruda (Colin Webb, 2021-05-11)
    Trub is the second-largest residue from brewing industry (250 thousand tons/year) and, due to the presence of high amounts of carbon and nitrogen, it is a potential source of reducing sugars and nitrogen for biological ...
  • COVID-19 trend analysis in mexican states and cities 

    Paiva, Henrique Mohallem [UNIFESP]; Afonso, Rubens Junqueira Magalhães; Sanches, Davi Gonçalves [UNIFESP]; Pelogia, Frederico José Ribeiro [UNIFESP] (Institute of Electrical and Electronics Engineers (IEEE), 2021-12-09)
    This paper presents a trend analysis of the COVID-19 pandemics in Mexico. The studies were run in a subnational basis because they are more useful that way, providing important information about the pandemic to local ...
  • Vibrational circular dichroism for the assignment of absolute configuration of natural products in Brazil 

    Batista, Andrea Nastri de Luca; Santos Junior, Fernando Martins dos; Valverde, Alessandra Leda; Batista Junior, João Marcos [UNIFESP] (Springer, 2021-12-02)
    The determination of the absolute configuration of chiral bioactive natural products is a crucial step in their structural characterization. Several well-established techniques, such as X-ray crystallography, stereo-controlled ...
  • Study of the COVID-19 pandemic trending behavior in Israeli cities 

    Paiva, Henrique Mohallem [UNIFESP]; Afonso, Rubens Junqueira Magalhães; Sanches, Davi Gonçalves; Pelogia, Frederico José Ribeiro (International Federation of Automatic Control (IFAC), 2021-11-02)
    This paper studies the trending behavior of the COVID-19 dynamics in Israeli cities. The model employed is used to describe, for each city, the accumulated number of cases, the number of cases per day, and the predicted ...
  • Tackling Stereochemistry in Drug Molecules with Vibrational Optical Activity 

    Bogaerts, Jonathan; Aerts, Roy; Vermeyen, Tom; Johannessen, Christian; Herrebout, Wouter; Batista Junior, João Marcos [UNIFESP] (MDPI, 2021)
    Chirality plays a crucial role in drug discovery and development. As a result, a significant number of commercially available drugs are structurally dissymmetric and enantiomerically pure. The determination of the exact ...
  • Absolute Configuration Reassignment of Natural Products: An Overview of the Last Decade 

    Batista, Andrea N. L.; Angrisani, Bianca R. P.; Lima, Maria Emanuelle D.; da Silva, Stephanie M. P.; Schettini, Vitória H.; Chagas, Higor A.; dos Santos Junior, Fernando M.; Batista Junior, João Marcos [UNIFESP]; Valverde, Alessandra L. (SBQ, 2021)
    The assignment of absolute configuration (AC) is a crucial step in the structural characterization of natural products, especially for those subjected to biological assays. Methods such as X-ray crystallography, stereocontrolled ...
