Objective: The objective of this research was to analyze the importance biotechnology in solid waste management, highlighting its applications, benefits, challenges and barriers that hinder large-scale implementation. Methodology: adopted an exploratory approach, using semi-structured interviews with 17 professionals field sustainability. Data collection carried out through these interviews, which allowed a qualitative analysis participants' perceptions, experiences knowledge about use...
Ferrites have been widely studied for their use in the biomedical area, mostly due to magnetic properties, which gives them potential be used diagnostics, drug delivery, and treatment with hyperthermia, example. In this work, KFeO2 particles were synthesized a proteic sol-gel method using powdered coconut water as precursor; is based on principles of green chemistry. To improve its base powder obtained was subjected multiple heat treatments at temperatures between 350 1300 °C. The samples...
Cancer is a major worldwide public health problem. Although there have already been astonishing advances in cancer diagnosis and treatment, the scientific community continues to make huge efforts develop new methods treat cancer. The main objective of this work prepare, using green sol–gel method with coconut water powder (CWP), nanocomposite mixture Gd3Fe5O12 ZnFe2O4, which has never synthesized previously. Therefore, we carried out structural (DTA-TG X-ray diffraction), morphological...
Cancer is one of the leading causes death worldwide. Conventional treatments such as surgery, chemotherapy, and radiotherapy have limitations severe side effects. Magnetic hyperthermia (MH) an alternative method that can be used alone or in conjunction with chemotherapy to treat cancer. Cobalt ferrite particles were synthesized using innovative biogenic sol–gel powder coconut water (PCW). The obtained powders subjected heat between 500 °C 1100 °C. Subsequently, they characterized by thermal,...
Background/Objectives: The unique properties of iron oxide nanoparticles have attracted significant interest within the biomedical community, particularly for magnetic hyperthermia applications. Various synthesis methods been developed to optimize these nanoparticles. Methods: In this study, we employed a powdered coconut water (PCW)-assisted sol–gel method produce magnetite first time. A comprehensive analysis thermal (differential and thermogravimetry), structural (X-ray diffraction),...
This work proposes the synthesis of strontium ferrite by two different methods: sol-gel (SG), using powdered coconut water (PCW) as a precursor, and laser floating zone (LFZ). The SG samples were after treated at temperatures 700, 1000, 1200 °C, while obtained LFZ grown pulling rates 10, 50, 100 mm/h. All studied subjected to structural characterization techniques, well electrical (AC DC) magnetic characterization. Through X-ray diffraction, it was possible observe that all presented...
Na1.5MnII3MnIII0.5(AsO4)3 and Na1.5MnII3FeIII0.5(AsO4)3 compounds were synthesized via a high-temperature solid-state combustion reaction. The obtained samples submitted to structural, morphological, electrical characterizations. X-ray diffraction measurements revealed that both crystallize in the monoclinic system with space group P21/c. lattice parameters determined be = 6.78344 Å, b 12.93830 c 11.22825 β 98.5374° for Na1.5MnII3MnIII0.5(AsO4)3, 6.76723 12.9864 11.256 98.8636°...
