“…Ref [14] menjelaskan bahwa proses perlakuan kimia dengan menggunakan metode pengendapan dapat mempengaruhi beberapa sifat dari material oksida logam seperti impuritas, aglomerasi dan fase yang terbentuk, karena itu pengkajian lebih dalam tentang proses sintesis pada sampel oksida logam banyak dilakukan. Teknik presipitasi menjadi pilihan para peneliti sebab memiliki banyakkelebihan diantaranya proses perlakuan yang simpel serta harga yang terjangkau.…”

<p>Hydrogen is an alternative energy that has a very abundant amount in nature, three-fourths of all elements in nature are hydrogen. Abundance can be developed because it can be converted into electrical energy and is expected to be able to replace fossil materials that are increasingly depleting in the future. For the management of hydrogen, a very safe storage is needed. One of the efforts by inserting hydrogen in certain metals. Magnesium is one material that is able to absorb hydrogen. But it has a disadvantage, namely the absorption and release time is very slow, this is due to the strong bond between hydrogen and magnesium. Several attempts have been intensively studied to improve the properties of Magnesium including the use of materials in the form of nanocrystals with Mechanical alloying techniques and efforts to add certain catalysts are now being actively studied. Research on the addition of Hematite (Fe2O3) catalysts to hydrogen storage materials has been carried out through Mechanical alloying techniques based on MgH2-Fe2O3. Hematite purely derived from nature has been successfully extracted chemically (precipitation method). The milled MgH2-Fe2O3 alloy samples were then analyzed by XRD and showed that the MgH2-Fe2O3 material was successfully reduced to the nanocrystal scale. The addition of catalysts and extended milling time also showed a decrease in desorption temperature.</p>

“…Os materiais reduzidos a 400 ºC, 600 ºC e 800 ºC removeram 32%, 21% e 5% do carbono orgânico total (COT), respectivamente. SHEN et al, (2013) realizaram um trabalho sobre o reaproveitamento do pó do alto-forno na produção de pigmento preto à base de óxido de ferro (Fe 3 O 4 ) em escala nanométrica. Os resultados mostraram que pigmento de Fe 3 O 4 resultante do pó do alto-forno sob condições otimizadas, possui reflectância menor que 4%, o que significa que o pigmento é totalmente preto, e uma boa absorção de óleo visto que o valor encontrado foi 23% e os pigmentos pretos possuem um desempenho pronunciado quando a absorção de óleo está entre 15% e 25%.…”

A indústria siderúrgica produz uma quantidade elevada de resíduos durante os seus processos produtivos. Dessa forma, tendo em vista a redução dos impactos causados ao meio ambiente, o setor siderúrgico incentiva a transformação desses resíduos em coprodutos que podem ser utilizados em substituição aos recursos naturais e com isso reduzir os custos na produção, melhorar o desempenho dos materiais produzidos e diminuir os impactos ambientais. Os principais coprodutos gerados pela siderurgia são os pós, as lamas, as escórias e as carepas. O pó do alto-forno é um coproduto obtido no sistema de limpeza a seco dos gases do alto-forno produzidos no processo de fabricação do ferro-gusa. A composição do pó do alto-forno depende das matérias-primas utilizadas no alto-forno, mas é basicamente composto de óxidos metálicos e materiais carbonosos. Pesquisas recentes apresentam alternativas de aproveitamento do pó do alto-forno na sinterização, na indústria cerâmica, na fabricação de briquetes, na produção de pigmentos, na indústria de cimento, no tratamento de águas residuais, entre outros. Assim, este trabalho tem por finalidade expor uma visão geral sobre as alternativas de aproveitamento do pó do alto-forno, apresentando os resultados dos estudos realizados com esse coproduto. Os resultados apontam que o uso do coproduto se mostrou vantajoso na maioria das aplicações.

“…Magnetic nanoparticles (MNPs) are among the most studied materials in recent decades due to the variety in their applications. [1][2][3][4][5][6][7] Their magnetic properties have led to important advances in several areas, including catalysis, magnetic resonance imaging techniques, [8,9] photothermal therapy agents, [10] and theragnostic [11] or hyperthermia cancer treatment agents. [12] Among these magnetic materials, Fe 3 O 4 magnetite materials have been widely studied due to their strong magnetic properties and they have been the subject of a large number of publications.…”

We report a simple solvothermal method for the synthesis of monodisperse magnetite nanoparticles with a controlled particle size within the range of 40 to 200 nm from available and inexpensive single iron precursor (FeCl 3) and, as co-capping agents, sodium acetate and ethylene diamine. The particle size can be easily controlled by the reaction time of synthesis. Transmission electron microscopy, x-ray diffraction, Fourier transform infrared spectroscopy, and x-ray photoelectron spectroscopy techniques were used to investigate the obtained particles. The results revealed that the resulting iron oxide particles exhibit a single magnetite Fe 3 O 4 phase and high stability in air even for four months. The high air stability of these magnetite could be due to the surfactant capped on the particle surface. This method of synthesis has some advantages including simplicity, high product quality, and acceptable reproducibility. Therefore, the magnetite particles can be used for different applications such as in catalysis and drug delivery.
