Green Synthesis of Titanium Oxide Nanoparticles Using Natural Extracts

引用

Journal of Materials Science and Chemical Engineering 2023年第2期11卷 29-40页

作者： Maribel Santiago Daniela Rivera Agustín torres Chemical Engineering department Tecnológico Nacional de México Atitalaquia Campus Atitalaquia México Basic Sciences department Tecnológico Nacional de México Atitalaquia Campus Atitalaquia México

Green synthesis is an alternative method for obtaining nanoparticles for environmentally friendly purposes. The present work describes the synthesis and characterization of titanium oxide nanoparticles, starting from three natural sources: orange peel, hibiscus rosa sinensis and Aloe vera. Titanium (IV) tetrabutoxide in ethanol solution was used as precursor. The methodology used was based on the sol-gel technique, through which TiO2 nanoparticles were obtained in the anatase phase. The characterization of the nanoparticles was carried out by means of x-ray diffraction (XRD), scanning electron microscopy (SEM) and infrared spectrophotometry (FTIR), which allowed the identification of a good degree of purity and crystallinity of the samples obtained.

Nexus of Climate Change and USA Mid-South Rice (<i>Oryza sativa</i>L.) Production

引用

Journal of Geoscience and Environment Protection 2020年第12期8卷 211-231页

作者： Michael Aide Christian torres de Guzman department of Agriculture Southeast Missouri State University Cape Girardeau MO USA University of Arkansas Fayetteville AR USA

Climate change is manifesting across the USA Mid-South and is impacting agricultural productivity, including the production of rice. This manuscript is a review of pertinent global literature concerning the effect of increasing temperature and carbon dioxide concentrations involving: 1) rice growth and development with an emphasis on spikelet sterility, 2) water availability for irrigation with the specter of aquifer overdraft and emerging water management technologies intended to improve water use efficiency, 3) the soil-plant continuum related to greenhouse gas emission and research avenues supporting agronomic practices that limit these emissions, and 4) region wide assessment of the economic and agronomic indicators to infer changes in the agricultural infrastructure and markets. Based on the global literature review and specific circumstances for USA Mid-South rice production, explicit proposals to mitigate and alleviate climate change are proposed. Key climate change mitigation proposals include: 1) support irrigation technologies that limit water usage and reduce methane emissions, 2) support soil carbon enhancement and newly emerging soil health agronomic practices, 3) achieve a greater usage of remote sensing activities to detect, in real time, field stresses, 4) support rice breeding activities that benefit furrow irrigation and provide heat tolerance, and 5) coordinate a rice region wide consensus to achieve farm gate activities that address climate change.

Two nanostructured A1-Cu-Fe alloys, A164Cu24Fe12 and A162.5Cu25.2Fe12.3, have been studied. Icosahedral quasicrystalline （ψ） A164CH24FeI2 and crystalline cubic （ β） ***25.2Fe12.3 cylindrical ingots were first produced using normal casting techniques. High-energy mechanical milling was then conducted to obtain β icosahedral and β intermetallic nanostructured powders. Electrochemical impedance spectroscopy, linear polarization resistance, and potentiodynamic polarization were used to investigate the electrochemical corrosion characteristics of the powders in solutions with different pH values. Current density （icorr）, polarization resistance （Rp）, and impedance modulus （121） were determined. The results showed that regardless of pH value, increasing the solution temperature enhanced the corrosion resistance of the both phases. However, the electrochemical behavior of the phase indicated that its stability depends on the submerged exposure time in neutral and alkaline environments. This behavior was related to the type of corrosion products present on the surfaces of the particles along with the diffusion and charge-transfer mechanisms of the corrosion process.

Variational Calculus With Conformable Fractional derivatives

IEEE/CAA Journal of Automatica Sinica 2017年第2期4卷 340-352页

作者： Matheus J.Lazo delfim F.M.torres Instituto de Matemática Estatística e Física-FURG Center for Research and development in Mathematics and Applications (CIDMA) Department of MathematicsUniversity of Aveiro

Invariant conditions for conformable fractional problems of the calculus of variations under the presence of external forces in the dynamics are studied. depending on the type of transformations considered, different necessary conditions of invariance are obtained. As particular cases, we prove fractional versions of Noether's symmetry theorem. Invariant conditions for fractional optimal control problems, using the Hamiltonian formalism, are also investigated. As an example of potential application in Physics, we show that with conformable derivatives it is possible to formulate an Action Principle for particles under frictional forces that is far simpler than the one obtained with classical fractional derivatives.

Constrained Fractional Variational Problems of Variable Order

引用

IEEE/CAA Journal of Automatica Sinica 2017年第1期4卷 80-88页

作者： Dina Tavares Ricardo Almeida delfim F.M.torres department of Mathematics Polytechnic Institute of Leiria department of Mathematics University of Aveiro

Isoperimetric problems consist in minimizing or maximizing a cost functional subject to an integral *** this work, we present two fractional isoperimetric problems where the Lagrangian depends on a combined Caputo derivative of variable fractional order and we present a new variational problem subject to a holonomic constraint. We establish necessary optimality conditions in order to determine the minimizers of the fractional problems. The terminal point in the cost integral,as well as the terminal state, are considered to be free, and we obtain corresponding natural boundary conditions.

Immediate–Early(IE) gene regulation of cytomegalovirus:IE1-and pp71-mediated viral strategies against cellular defenses

引用

Virologica Sinica 2014年第6期29卷 343-352页

作者： Lilith torres Qiyi Tang department of Microbiology Ponce Health Sciences UniversityPonce Research InstitutePoncePR 00716USA

Three crucial hurdles hinder studies on human cytomegalovirus(HCMV): strict species specificity, differences between in vivo and in vitro infection, and the complexity of gene regulation. Ever since the sequencing of the whole genome was first accomplished, functional studies on individual genes have been the mainstream in the CMV field. Gene regulation has therefore been elucidated in a more detailed fashion. However, viral gene regulation is largely controlled by both cellular and viral components. In other words, viral gene expression is determined by the virus–host interaction. Generally, cells respond to viral infection in a defensive pattern; at the same time, viruses try to counteract the cellular defense or else hide in the host(latency). Viruses evolve effective strategies against cellular defense in order to achieve replicative success. Whether or not they are successful, cellular defenses remain in the whole viral replication cycle: entry, immediate–early(IE) gene expression, early gene expression, DNA replication, late gene expression, and viral egress. Many viral strategies against cellular defense, and which occur in the immediate–early time of viral infection, have been documented. In this review, we will summarize the documented biological functions of IE1 and pp71 proteins, especially with regard to how they counteract cellular intrinsic defenses.
