Abstract:
A simple and rapid microwave-assisted extraction (MAE) technique was developed for the extraction of rutin fromLespedeza virgata(Thunb.) DC. The influence of four extraction variables on extraction of rutin was discussed. The optimum extraction conditions found were 75% aqueous ethanol, solvent volume to sample weight ratio at 90 : 1, extracting temperature at75°C, and extraction time for 15 min. A comparison was made among MAE, classical maceration, and ultrasonic-assisted extraction (UAE). Yields were determined by high-performance capillary electrophoresis (HPCE). The whole analysis process was completed in ten minutes. The needful volumes of sample and buffer are very little. Compared with maceration and ultrasonic extraction, MAE is a rapid method with higher yield and less solvent consumption.

Abstract:
A review of recent results concerning the DC characterization of FD- and Double Gate SOI MOSFET’s and FinFETs in modern CMOS technologies is given. By proper extraction techniques, distinction between the different interaction mechanisms is done. Parameter extraction conducted at room and low temperature clearly indicates that the mobility is directly impacted by shrinking the gate length in sub 100nm architectures.

During its evolutionary process, plants have developed biosynthetic pathways by which they produce and accumulate a wide variety of secondary compounds that receive this name because they are not directly involved in the primary processes of plant growth and development. Many of these secondary compounds are responsible for chemical protection of plants against pathogens, herbivores, competing plants, ultraviolet radiation and other environmental stresses. The production of secondary metabolites can vary quantitatively and qualitatively between individuals of the same species, between plants of different species, between organs, between stages of plant development and are under influences of environmental factors. Studies of the biological effects of these compounds represent an important tool for the development of more specific and natural pesticides that are less harmful to the environment, as well as drugs and natural preservatives for food. Myrcia splendens (Sw.) DC. is a tree species found in the Brazilian cerrado and there are few published papers dealing with this species and its secondary metabolites to act as potential natural pesticides, antioxidant and antifungal. The methodology for the extraction of secondary metabolites can determine the composition of extracts and influence the activity of them. In this sense, in the first chapter of this work investigations were carried out on the phytotoxic potential of extracts of M. splendens young leaves from two different extraction methodologies. The 2C extract had the highest overall phytotoxic activity, showing promise in the search phytotoxic substances. In the second chapter, we investigate the phytotoxic potential of extracts and fractions of mature leaves of M. splendens from the two extraction methods carried out and was identified one of the secondary metabolites possibly associated with the phytotoxicity of the most active fractions. 2B fraction had the highest total inhibitory activity and so was fractionated, resulting in 14 fractions, which were also tested in wheat coleoptile. The FM8 and FM9 fractions, which had inhibitory activity and sufficient income, were subjected to HPLC for isolation of major compound. Identification by NMR spectra revealed that the major compound is miricitrin (myricetin-3-O-rhamnoside). In the last chapter, the extracts of mature leaves of M. splendens were tested for their antioxidant potential based on their ability to react with the free radical DPPH (2,2-diphenyl-1-picrylhidrazila) and antifungal potential using the plant pathogenic fungus Alternaria alternata as the target species. Most of the extracts showed a strong antioxidant activity, especially those iv! ! extracted with more polar solvents. On the other hand, only one of the extracts (2B) showed inhibitory activity on mycelial growth of the phytopathogenic fungus tested.
Ao longo do seu processo evolutivo, as plantas desenvolveram rotas biossintéticas pelas quais produzem e acumulam uma imensa variedade de compostos secundários, que recebem este nome por não estarem diretamente envolvidos nos processos primários de crescimento e desenvolvimento vegetal. Muitos desses compostos secundários são responsáveis pela defesa química das plantas contra patógenos, herbívoros, plantas competidoras, radiação ultravioleta e outros estresses ambientais. A produção de metabólitos secundários pode variar quantitativa e qualitativamente entre indivíduos de uma mesma espécie, entre plantas de espécies diferentes, entre órgãos, entre estágios do desenvolvimento vegetal e sobre influências de fatores ambientais. Os estudos realizados sobre os efeitos biológicos destes compostos representam uma importante ferramenta para o desenvolvimento de agroquímicos naturais mais específicos e menos prejudiciais ao ambiente, bem como de medicamentos e conservantes naturais para a indústria alimentícia. Myrcia splendens (Sw.) DC. é uma especie arbórea encontrada no cerrado brasileiro e existem poucos os trabalhos publicados que tratam de investigações do potencial desta espécie e de seus metabólitos secundários para atuarem como pesticidas naturais, antioxidantes e antifúngicos. A metodologia empregada para a extração de metabólitos secundários pode determinar a constituição e rendimento dos extratos e influenciar a atividade dos mesmos. Nesse sentido, no primeiro capítulo deste trabalho foram realizadas investigações sobre o potencial fitotóxico de extratos de folhas jovens de M. splendens oriundos de duas metodologias de extração diferentes. O extrato 2C teve a maior atividade fitotóxica geral, se mostrando promissor na busca de substâncias fitotóxicas. No segundo capítulo, foi investigado o potencial fitotóxico de extratos e frações de folhas maduras de M. splendens das duas metodologias de extração realizadas e foi identificado um dos metabólitos secundários possivelmente associado à fitotoxicidade das frações mais ativas. A fração 2B apresentou a maior atividade inibitória total e por isso foi fracionada, resultando em 14 frações, que também foram testadas em coleóptilos de trigo. As frações FM8 e FM9, que possuíam atividade inibitória e rendimento suficiente, foram submetidas a CLAE para isolamento do composto majoritário. A identificação foi feita por espectros de RMN e revelou que o composto majoritário é a miricitrina (miricetina-3-O-ramnosídeo). No último capítulo, os extratos de folhas maduras de M. splendens foram testadas quanto ao seu potencial antioxidante baseado habilidade de reagir com o radical livre DPPH (2,2-difenil-1-picrilhidrazila) e antifúngico usando como espécie-alvo o fungo fitopatogênico Alternaria ii! ! alternata. A maior parte dos extratos apresentaram atividade antioxidante muito forte, especialmente aqueles extraídos com solventes mais polares. Por outro lado, apenas um dos extratos (2B) apresentou atividade inibitória no crescimento micelial do fitopatógeno testado.

Abstract:
O araçá é um fruto, pertencente à espécie Psidium grandifolium Mart. ex DC, nativo da mata atlântica brasileira pouco caracterizado pela literatura ciêntífica. Esta pesquisa visou estudar o rendimento de extração e avaliar as atividades antioxidante e antimicrobiana do óleo essencial de araçá obtido por extração com dióxido de carbono supercrítico (SFE) e dos diferentes extratos obtidos por extração com etanol pressurizado (PLE) seguindo um delineamento composto central rotacional com temperatura e tempo estático como variáveis independentes estudadas. Avaliou-se também o perfil de voláteis do óleo essencial, o teor de compostos fenólicos totais dos extratos etanólicos e as alterações causadas na matriz vegetal por diferentes processos de extração. Com a SFE conseguiu-se extrair toda a fração lipídica do fruto (2,33% ± 0,04.10-2%), a análise dos compostos voláteis do óleo essencial obtido permitiu inferir que este possui diversos compostos com potencial bioativo tais como E-cariofileno (17.56%), α-humuleno (16,26%) e β-sesquifelandreno (14.27%); porém este óleo essencial não apresentou atividade antioxidante relevante. O extrato etanólico com maior rendimento (17, 49%) foi obtido a 74 °C por 6 min, mesma condição em que obteve-se a maior atividade antioxidante (EC50 = 6,37 mg/mL), porém o maior teor de compostos fenólicos totais (136,95 mg EGA/100 g de massa seca) foi obtido quando aplicou-se 60°C por 9 min. Em relação à atividade antimicrobiana, tanto os extratos obtidos por PLE quanto por SFE apresentaram atividade contra cepas de P. aeruginosa, S. aureus e B. cereus, somente extratos etanólicos apresentaram atividade contra cepas de L. monocytogenes e nenhum dos extratos apresentaram atividade contra cepas de B. subtilis, E. coli e Salmonella. Em ambos os extratos foi possível identificar compostos com potencial aplicação farmacológica. O estudo de processos de extração que envolvam inovação tecnológica na obtenção extratos com atividade biológica visa contribuir com o extrativismo consciente ou estimular o plantio em maior escala de mais um fruto tropical empregado na medicina popular brasileira.
The araçá is a fruit, belonging to the species Psidium grandifolium Mart. ex DC, native of the Brazilian Atlantic Forest, is not largely characterized by the scientific literature. This research work aimed to study the extraction yield and to evaluate the antioxidant and antimicrobial activities of the araçá essential oil obtained by supercritical carbon dioxide extraction (SFE) and the different extracts obtained by pressurized ethanol extraction (PLE) following a central composite design with temperature and static time as independent variables studied. It was also evaluated the volatile profile of the essential oil, the content of total phenolic compounds of the ethanolic extracts and the changes caused in the vegetal matrix by different extraction processes. SFE was able to extract the whole lipid fraction of the fruit (2.33% ± 0.04.10-2%), the analysis of the volatile compounds of the essential oil obtained allowed to infer that it has several compounds with bioactive potential such as E-caryophyllene (17.56%), α-humulene (16.26%) and β-sesquipelandene (14.27%); but this essential oil had no relevant antioxidant activity. The highest ethanolic extract (17, 49%) was obtained at 74 °C for 6 min, the same condition in which the highest antioxidant activity was obtained (EC50 = 6.37 mg/mL), but the higher content of total phenolics contente (136.95 mg EGA / 100 g dry mass) was obtained when 60 °C was applied for 9 min. In relation to the antimicrobial activity, both extracts obtained by PLE and SFE showed activity against P. aeruginosa, S. aureus and B. cereus strains, only ethanolic extracts showed activity against L. monocytogenes strains and none of the extracts presented activity against B. subtilis, E. coli and Salmonella strains. In both extracts it was possible to identify compounds with potential pharmacological application. The study of extraction processes that involve technological innovation in obtaining extracts with biological activity aims to contribute to the conscious extraction or stimulate the larger scale cultivation of another tropical fruit used in Brazilian popular medicine.

Abstract:
Atmospheric-pressure plasmas have a wide variety of potential industrial applications. They are used in extractive metallurgy; metal recovery; novel nanomaterial synthesis; refractory and wear-resistant coatings deposition; chemical synthesis; energy conversion; industrial, medical, and nuclear waste destruction; engine combustion enhancement; and exhaust gas pollutants clean up. Atmospheric plasmas are produced by applying DC or AC high voltage between two electrodes designed as cylindrical in shape for jets and planar for the dielectric barrier discharge systems. This review presents an overview of the use of atmospheric-pressure plasma devices and industrial processes carried out in several of these areas.

Abstract:
Abstract This paper presents design, analysis, manufacturing, and prototyping of an electric pollen extractor. The design project is based on a request from the Washington State Department of Natural Resources (DNR) to build a machine for extracting pollen from tree catkins. The machine designed at a low cost can shake off pollen from catkins cleaner and faster than other devices. The extractor can shake the pollen and clean the seeds faster by assembling a 6-volt DC gearbox motor, a drive wheel to stabilize the rotation of the extractor, and a vibrator to help shaking the pollen during the filtration process. The design idea is modeled in Autodesk Inventor and safety-factor-based design calculations are carried out, mechatronic circuits are designed and further CFD and FEA simulations are performed in Ansys to verify the validity of the design. The rotational speed of the extractor is selected based on the required motion for particles. After completion of the preliminary analysis, the design changes are passed through another round of testing. The first round of testing produced a positive change, eliminating some material, and lowering cost. Second round showed promising results with speeding up extraction time. Final design, prototype and successful testing results of the extractor is presented in the paper with concluding remarks and future work.
