Abstract: This article presents a Co phase segregation strategy for creating stable Co cluster catalytic sites on TiO2, enabling selective CO2 hydrogenation to CO. Through oxidative calcination, pre-synthesized Co-doped brookite TiO2 nanorods transform into a mixed TiO2 phase, leading to the phase segregation of Co species. The resulting Co clusters, stabilized by strong Co-TiO2 interactions during reductive CO2 hydrogenation, effectively suppress the formation of larger nanoparticles. The undercoordinated sites of these clusters promote a high CO production rate with near-unit selectivity, contrasting with Co nanoparticles, which favor CH4 formation under identical conditions. In-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis indicates that the weakened CO adsorption on Co clusters is key to their enhanced CO selectivity, highlighting this method as a promising approach for efficient CO2 utilization.

No Brasil, as políticas públicas voltadas para as habitações em assentamentos da reforma agrária são efetivadas pelo fornecimento de crédito às famílias dos agricultores familiares, aplicados na construção e reforma. Mesmo com a obrigatoriedade de se ter assistência técnica especializada, evidenciam-se moradias com problemas relacionados ao dimensionamento, distribuição, acabamento e qualidade construtiva. O objetivo do estudo é analisar o impacto do acesso ao Crédito Habitacional no grau de consolidação das moradias em assentamentos da reforma agrária em Mato Grosso, Brasil. A metodologia consiste em uma etapa de diagnóstico do perfil do agricultor familiar e da moradia, em uma amostra de 11.205 lotes e, na avaliação do grau de consolidação das moradias, obtido por meio de inspeção visual em imagens de 3.069 lotes. Os resultados evidenciam que o grau de consolidação da moradia e o acesso à linhas de crédito para habitação estão diretamente relacionados: 35% dos respondentes dos lotes que declararam ter acessado linhas de crédito para a construção, tem suas moradias avaliadas com Grau Alto de consolidação e 61% dos assentados em moradias com Grau Baixo de consolidação declararam não ter acessado linha de crédito. Todavia, destacam-se os 45% das moradias com baixo grau de consolidação e que acessaram linhas de crédito, porém não finalizaram a construção da habitação. Percebe-se que o acesso à linha de crédito sem a devida assitênvia técnica e planejamento do projeto e construção não garante a condição de habitabilidade das moradias.

Introdução: O câncer de pulmão é uma das causas de mortalidade relacionadas ao câncer no mundo. O tipo mais frequente é o de não pequenas células. O tratamento cirúrgico é indicado nos estágios iniciais. Objetivo: Analisar a importância do tratamento cirúrgico nos pacientes com câncer de pulmão de não pequenas células. Metodologia: Trata-se de uma revisão integrativa dos últimos 5 anos, do período de 2020 a 2025, utilizando as bases de dados Latino–Americana e do Caribe em Ciências da Saúde (LILACS), Medline e Coleciona SUS. Os descritores que foram utilizados: "carcinoma" "pulmão" "tratamento" "cirurgico". Foram encontrados 39 artigos, sendo eles submetidos aos critérios de seleção. Além disso, foi utilizado um documento de pneumologia prática. Os critérios de inclusão foram artigos em inglês, portugues e espanhol que se relacionavam à proposta estudada e que foram disponibilizados na íntegra. Resultados e Discussão: A cirurgia é o tratamento padronizado para esse tipo de câncer. Quanto mais inicial o câncer, mais utilizado é o tratamento cirúrgico. A cirurgia minimamente invasiva (CMI) está cada vez mais utilizada, por apresentarem menores chances de complicação, dor pós-operatória, internação hospitalar, além de melhorar a qualidade de vida, quando se comparada a cirurgias abertas como a toracotomia. A cirurgia em pacientes idosos também é indicada a depender das particularidades do paciente. Procedimentos cirúrgicos como mediastinoscopia cirúrgica pode ser utilizada no estadiamento das doenças e logo, auxiliar na escolha da terapêutica. Conclusão: Nessa perspectiva, evidencia-se a importância do tratamento cirúrgico para melhora do prognóstico do paciente nos estágios iniciais.

Published: January 2025

Do milho é extraído o amido, conhecido como amido de milho (Zea Mays). É um pó fino, branco, inodoro, insípido e produz ligeira crepitação quando comprimido com os dedos. O amido e uma substância de reserva em plantas, é formado de amilose e amilopectina. Tem uma grande aplicação na indústria em geral, principalmente na indústria de papel e celulose. O amido oxidado surgiu da necessidade específica da indústria que não podia ser atendida como o uso do amido “in natura”. O presente trabalho objetivou-se em avaliar a viscosidade durante o processo de reação de amidos de reprocesso e não reprocessados quanto a dosagem de químicos em especial NaClO. Após condução do processo de oxidação dos amidos de milho em 4 tanques com 9,5% de sólidos padronizados, verificou-se pequena variação no teor de proteína, a qual retarda a reação de oxidação dos amidos, os parâmetros de percentuais de soda e cloro livre se mantiveram dentro dos parâmtetros respectivamente de, 4 a 6% de soda e 11 a 13% de cloro livre. A menor viscosidade determinada em viscosímetro RVA determinada foi de 189 cP e a menor temperatura de empastamento foi 74,35ºC, com menor tendência a retrogradação. O controle das condições de oxidação, como teor proteico, concentração de hipoclorito de sódio, temperatura e pH, é crucial para alcançar as modificações desejadas nas propriedades dos amidos. As variações nas viscosidades das amostras e suas tendências à retrogradação fornecem informações valiosas para a aplicação industrial de amidos modificados.
