    OSHIRO, MAURICIO T. ; SAKATA, SOLANGE K. ; POTIENS JUNIOR, ADEMAR J. . Adsorption isotherms for the removal of Am-241 in radioactive liquid wastes using magnetite nanoparticles. In: PAN AMERICAN CONGRESS OF NANOTECHNOLOGY, 1st, 27-30 de novembro, 2017, Guarujá, SP. Abstract... 2017.

    Abstract: Americium-241 (Am-241) is a radionuclide with half-life of 432 years, emitting alpha particles and low gamma energy and it is also considered radiotoxic. Am-241 is produced, in a low level, from nuclear fuel and laboratory wastes. Magnetite nanoparticles (Fe3O4) are iron oxides that possess highly magnetic properties, and its application for removal of water contaminants refers due to its high surface area which allows the adsorption capability and the facility to be prepared and removed from the aqueous medium. In This study, magnetite was synthesized by coprecipitation method largely described. Batch experiments were accomplished at room temperature, at pH 6 and the contacts varying from 2.5, 5, 10, 20, 30, 40, 50, 60 minutes and at 30 minutes for the isotherms experiments. The solid containing magnetite and Am-241 were removed with a magnet and the solution analyzed in a gamma-ray spectrometer (Canberra Model GX2518) which could be quantified. Results show that magnetite possess a capability of removal up to 80% of Am-241 at room temperature, indicating that magnetite nanoparticles are a good sorbent for the removal of radionuclides. Langmuir and Freundlich Isotherms models were investigated and the parameters obtained. Langmuir’s isotherm showed constants of KL (75.7575 L/mg), Q (0.1617 mg/g) and R2 (0.9892) and Freundlich’s isotherm exhibited values of KF (2.6416 [(mg/g).(L/mg)1/n]), 1/n (0.7853 mg/g) and R2 (0.8395), which indicates that the Am- 241 removal from magnetite fits more suitable the Langmuir isotherm model. The thermodynamics parameters, such as the enthalpy and entropy of adsorption, the activation energy, as well as, the kinetics studies are under development.

    ROVANI, SUZIMARA ; SANTOS, JONNATAN J. ; CORIO, PAOLA; FUNGARO, DENISE A. . Adsorption of bisphenol-A in aqueous solution using silica nanoparticles obtained from sugarcane ash. In: AMERICAN CHEMICAL SOCIETY. DIVISION OF CELLULOSE & RENEWABLE MATERIALS. NATIONAL MEETING & EXPOSITION, 255th, March 18-22, 2018, New Orleans, LA. Abstract... 2018.

    Abstract: Scientists around the world have searched minimize problems related to the incorrect disposal of solid wastes and water contamination. Brazil, for example, is the largest producer of sugarcane in the world, generates around 3-12 million of tons ash/year or more, and this waste can be transformed into valueadded material. In this study, we tried to solve two problems at the same time, manufacturing an adsorbent material and applies it in the remediation of contaminated water with bisphenol-A (BPA), an endocrine disrupting compounds, which alters plasma sex hormone levels in fishes [1]. The silica nanoparticles were synthetized through the addition of silicate obtained from sugarcane ash in the solution of water/butyl alcohol (1:1) with 2.5% wt. of hexadecyltrimethylammonium bromide under constant stirring. Then, 0.5 mol L-1 H2SO4 solution was added to suspension until pH 4. The nanosilica formed was washed with distilled water, filtered and dried. The silica nanoparticles and BPA adsorbed on silica were characterized by different techniques. The maximum BPA adsorption capacity obtained was 80 mg g-1. From TEM images (Fig. 1A-B) of the silica nanoparticles it is seen that all particles has less than 20 nm. Fig. 1C shows the infrared spectra of samples. The band at 1058 cm-1 is due to the Si–O–Si asymmetric stretching, the band at 965 cm-1 is due to Si-OH bending vibrational absorption, the bands at 799 and 446 cm-1 are due to the Si–O–Si symmetric stretching. The presence of other bands in the blue spectra are attributed of BPA adsorbed on silica nanoparticles, at 554 cm-1 is due to aromatic ring deformation vibration of di-substituted benzenes, at 834 cm-1 is assigned to C-H vibrations out of the plane and at 1512 cm-1 is due to aromatic C=C stretching vibration [2]. The results of characterization of the silica nanoparticles manufactured showed that the material presents potential to be employed as adsorbent for remediation of water contaminated with endocrine disrupting compounds.

    ROVANI, SUZIMARA ; SANTOS, JONNATAN J. ; CORIO, PAOLA; FUNGARO, DENISE A. . Adsorption study of acid orange 8 dye using silica nanoparticles obtained from sugarcane ash. In: PAN AMERICAN CONGRESS OF NANOTECHNOLOGY, 1st, November 27-30, 2017, Guarujá, SP. Abstract... 2017.

    Abstract: Developing of new adsorbents becomes a very important need, especially because of the increase of contaminants present in rivers, oceans and any other water body capable of became potable. Biosorbents has a special feature, because they can solve two problems at the same time, once they are prepared from a natural source, giving a utility for wasted materials, and bioremediate a water body, adsorbing contaminants on their surface. In this context, the properties of a biosorbent prepared from sugarcane ash by surfactant mediated synthesis has been studied to the adsorption of acid orange 8 dye, a model molecule, aiming future applications for removal of emerging contaminants of water. According to the results of adsorption kinetic (Fig. 1A), the acid orange 8 dye removal was higher than 89% and 95% in 4 h of contact time for an initial concentration of 200 and 150 mg L-1, respectively. FTIR-ATR analyses (Fig. 1B) indicated the presence of bands: at 799 and 446 cm-1 are due to symmetric stretching of siloxane groups, at 1058 cm-1 is due the Si–O–Si asymmetric stretching, at 2925 cm-1 and 2850 cm-1 are due to the bending of –CH3 and –CH2, respectively, for silica-CTAB sample and additionally, at 1031, 689 and 641 cm-1 are due sulfur groups (S=O), out-of-plane deformation of ring and aromatics groups, respectively, of acid orange 8 dye. In TGA analysis (Fig. 1C), the peak between 150 to 235 °C for silica-CTAB sample has been attributed to the unbound CTAB less stabilized bonding sites on the silica surface due to hydrophobic– hydrophobic interactions of interdigitated CTAB and the peak around 256 °C indicates a stronger bonding of the surfactant to the silica surface due to the electrostatic binding of the ammonium cation head group to the electronegative silica surface [1]. For the silica-CTAB + dye sample, the substitution of the interdigitated CTAB of a second layer by dye was observed by the disappearance of the DTG peak between 150 to 235 °C. The displacement the DTG peak of 256 for 300 °C and appearance of the DTG peak around 435 °C are related to the dye adsorption. These aspects demonstrate the potential of silica nanoparticles obtained from sugarcane ash as new biosorbent for removal of organic compounds, such as, dye from aqueous solution and can be used to alleviate environmental problems.

    MELLO-CASTANHO, S.R. ; SILVA, J.P. ; CARDOSO, S. . Advanced processing strategies for the development of energy efficient devices with eco-friendly, natural materials. In: INTERNATIONAL CONGRESS ON CERAMICS, 7th; CONGRESSO BRASILEIRO DE CERÂMICA, 62., June 17-21, 2018, Foz do Iguaçu, PR. Abstract... 2018. p. 995-995.

    Abstract: The search for green technologies and the reduction of environmental impacts has become a constant in the scenario of technology options worldwide and in particular in countries with emerging economies that adapt very easily to the new paradigms of sustainability. Therefore, it is essential to develop new processing strategies for the green manufacture of ceramics to preserve natural sustainability and to generate clean and sustainable energy resources in remote areas. Therefore, the future of ceramic materials requires now to search for simple technological options that result in the use of low energy consumption and low emission of effluents to the environment and low cost. Processes involving mimicry, reuse, recovery, simple value-added products, in short, the development of the methodologies with strong ecological appeal can effectively aid to the economic turnover in manufacturing processes and it is one of the major challenges since the end of last century. This work, dials with the development and optimization of energy efficient processes to generate clean and sustainable energy sources such as the surface activation of natural nanotubes based on Palygorskite clay and the use of vegetable fiber Luffa Cylindrical as replica in porous burner technology. In the first case the green chemistry on surface activation by change Mg cations by radionuclides Ni, Sr, in stable condition shows a promisor potential using this raw material in the mitigation by immobilization of industrial nuclear rejects. In the second one, the controlled colloidal processing shows that it is possible to use silicates to fabricate burning gas light with luminescent characteristics, resistant to use in remote places that have not yet the electric energy available for lightning.

    SANTIAGO, ELISABETE I. ; MATOS, BRUNO R. ; DRESCH, MAURO A.; ISIDORO, ROBERTA A. ; FONSECA, FABIO C. . Advances on Nafion-based composites for high temperature proton exchange membrane fuel cells. In: BRAZIL MRS MEETING, 16th, September 10-14, 2017, Gramado, RS. Abstract... São Carlos, SP: Aptor Software, 2017. p. 55-55.

    Abstract: PEMFC (Proton exchange membrane fuel cell) is considered a promising and efficient hydrogen fuelled electrical power source. However, PEMFC faces several technical problems, such as sluggish electrode reaction kinetics involving the limiting rate of the oxygen reduction and alcohol oxidation reactions, and high resistance to ion transport that could be surpassed with increasing of the operation temperature. The main impediment for such a temperature increase is the water dependent performance of the state-of-the-art Nafion electrolyte. Above 80 ºC water starts to evaporate considerably and Nafion microdomains begin to shrink, disrupting its percolative structure, leading from a conductor to insulator transition. In this work, the incorporation in-situ or ex-situ of an inorganic phase with hydrophilic properties, such as TiO2 and SiO2, into Nafion membranes has been evaluated as an interesting alternative to produce stable electrolytes able to operate at higher temperatures (130o C). The physical-chemistry and electrochemical characterisation has shown that the inorganic particles located in both the nonionic and ionic regions of the ionomer have important contributions to enhanced thermal stability and water uptake. Such features resulted in significant improvements of the PEMFCs using composite electrolytes tested at high operating temperature and low relative humidity. In addition, remarkable enhancement on the DEFC (Direct Ethanol Fuel Cell) performance (122 mW cm‑2) has been obtained as a result of an increase of ethanol oxidation reaction rate promoted by the combination of enhanced catalyst activity and high temperature of operation using stable composite Nafion-SiO2 electrolytes.

    RAMOS, LUIZ D.; MANTOVANI, MARIANA C. ; SARTORI, ADRIANO; DUTRA, FERNANDO; STEVANI, CASSIUS V.; BECHARA, ETELVINO J.H. Aerobic co-oxidation of hemoglobin and aminoacetone.

    Abstract: Aminoacetone (1-aminopropan-2-one), a putative minor biological source of methylglyoxal, reacts like other 􀄮-aminoketones such as 6-aminolevulinic acid (first heme precursor) yielding electrophilic 􀄮-oxoaldehydes, ammonium ion and reactive oxygen species by metal- and hemeprotein catalyzed aerobic oxidation 1,2. A wealth of reports implicates methylglyoxal in protein crosslinking and DNA addition, leading to age-related disorders, including diabetes 3,4. Importantly, methylglyoxal-treated hemoglobin adds four water-exposed arginine residues, which may compromise its physiological role and potentially serve as biomarkers for diabetes 5. In this work, we investigate the co-oxidation of aminoacetone and oxyhemoglobin in normally aerated phosphate buffer, leading to structural changes in hemoglobin, which might reportedly be attributed to the addition of aminoacetone-generated methylglyoxal to the protein. Hydroxyl radical-promoted chemical damage to hemoglobin may also occur in parallel, which is suggested by EPR-spin trapping studies with 5,5-dimethyl-1-pyrroline-N-oxide and ethanol. Concomitantly, oxyhemoglobin is oxidized to methemoglobin, as indicated by characteristic CD spectral changes in the absorption Soret and visible regions. Overall, these findings may contribute to elucidate the molecular mechanisms underlying human diseases associated with hemoglobin dysfunctions (e.g., diabetes) and with aminoacetone in metabolic alterations related to excess of glycine and threonine (e.g., threoninemia, cri-du-chat syndrome).

    LOPES, FABIO J.S. ; GUERRERO-RASCADO, JUAN L.; LANDULFO, EDUARDO ; KROTKOV, NICKOLAY; HUGHES, ERIC; SILVA, ARLINDO da. Aerosol layer observation of 2015 Calbuco volcanic eruption over the LALINET São Paulo station. In: WORKSHOP ON LIDAR MEASUREMENTS IN LATIN AMERICA, 9th, July 17-22, 2016, Santos, SP. Abstract... 2016.

    Abstract: On the 22nd of April 2015, the Calbuco volcano sited at the South region of Chile had its first eruption since 1972, injecting a huge plume of volcanic aerosol particles and gases up to 21 km into the atmosphere. As part of the Latin America Lidar Network’s (LALINET) aim to monitor any atmospheric event the LALINET São Paulo station (SPU) started continuous observation in order to monitor the dispersion of volcanic aerosol layer and their altitude and optical properties. After 5 days, on 27 April 2015, some volcanic plumes arrived over the Metropolitan area of São Paulo (MASP) and were detected by the SPU system within the altitude range of 18-19 km. The timing and altitude of SPU observations coincide with transport and dispersion simulations of the volcanic cloud’s arrival at São Paulo, from the Goddard Earth Observing System Model, version 5 (GEOS-5) and Goddard Chemistry Aerosol Radiation and Transport (GOCART) model from NASA Goddard Space Flight Center. The models simulate the volcanic eruption’s injection of SO2, SO4, and ash into the atmosphere and the advection of the volcanic plume away from the volcano. The purpose of this study is to determine the optical properties of the volcanic plume such as AOD and Lidar ratio. Applying the transmittance method used previously for cirrus clouds it was possible to retrieve the AOD value of 0.16 ± 0.21 and a lidar ratio of 64 ± 4 sr.

    OLIVEIRA, D.C.; HOELZEMANN, J.J.; LANDULFO, E. ; ARBOLEDAS, L.A.. Aerosol optical properties in the atmosphere of Natal/Brazil measured a sun photometer of the AERONET. In: SP SCHOOL OF ADVANCED SCIENCE ON ATMOSPHERIC AEROSOLS, July 22 - August 2, 2019, São Paulo, SP. Abstract... São Paulo, SP: Instituto de Física - USP, 2019. p. 95-95.

    Abstract: The study of atmospheric aerosols contributes to the understanding of radiative forcing and global warming. In addition, aerosols may influence visibility, acid rain, human health and precipitation. Since 2016, Natal, capital of Rio Grande do Norte, Brazil, has a solar photometer (CIMEL) of the RIMA-AERONET network that can identify the presence of biomass burning aerosols and desert dust from Africa. For this identification, it is aimed to characterize the optical properties of these aerosols present in the atmosphere of Natal (RN). The data available by AERONET, at level 1.5, Version 3, provide information on some microphysical characteristics such as Optical Aerosol Depth (AOD), Ångström coefficient ( ), Single Scattering Albedo (SSA), Asymmetry Factor (g), Complex Refractive Index (N), Volume Size Distribution (VSD) and Precipitable Water. The data collection period was from August 2017 to August 2018. Aerosols were classified based on global climatologies and their optical properties were described. Observations were compared with daily measurements from satellites and the local LIDAR over the course of a day for a case study. In addition, backward trajectories were modeled with the HYSPLIT model to verify the predominant origin of the air masses. Aerosols present in the atmospheric column of Natal showed monthly means of AOD in the range of 0.10 to 0.15 with peak of 40%, monthly means of between 0.6 and 0.8 with peak above 30%, bimodal DTV with dominant coarse mode, SSA about 0.8, real part around 1.5, imaginary part raging from 0.0125 to 0.0437 and g above 0.74. The Precipitable Water accompanied the increase of the precipitation for the months of December, January, February and March. The classification identified mixed aerosols (60.40%), marine aerosols (30.69%) and mineral dust (8.91%). The backward trajectories showed that in 51% of the cases the continental aerosols origined from the Africa.

Nesta primeira etapa de funcionamento do RI, a coleta das publicações é realizada periodicamente pela equipe da Biblioteca do IPEN, extraindo os dados das bases internacionais tais como a Web of Science, Scopus, INIS, SciElo além de verificar o Currículo Lattes. O RI-IPEN apresenta também um aspecto inovador no seu funcionamento. Por meio de metadados específicos ele está vinculado ao sistema de gerenciamento das atividades do Plano Diretor anual do IPEN (SIGEPI). Com o objetivo de fornecer dados numéricos para a elaboração dos indicadores da Produção Cientifica Institucional, disponibiliza uma tabela estatística registrando em tempo real a inserção de novos itens. Foi criado um metadado que contém um número único para cada integrante da comunidade científica do IPEN. Esse metadado se transformou em um filtro que ao ser acionado apresenta todos os trabalhos de um determinado autor independente das variáveis na forma de citação do seu nome.
