 The synthesis of mesoporous silica nanoparticles using non-surfactant agents is gaining popularity owing to the easier purification and lower toxicity of this method compared to traditional surfactant-based ones. The potential of mesoporous silica nanoparticles as advanced nanocarriers for health-related applications is increasingly recognized. Quercetin, a potent free-radical scavenging antioxidant that relies heavily on the intracellular supply of reduced glutathione, has garnered significant interest in the scientific community. In spite of recent progress, the mechanisms underlying the development of the porous framework have largely gone unexplored. The primary aim of this study is to explore the feasibility of utilizing quercetin as a template for the synthesis of mesoporous silica nanoparticles, circumventing the need for conventional This research investigates the impact of the chemical structure and properties of polyphenols, specifically quercetin, on their templating potential. The study reveals the arrangement of quercetin, which acts as a model for the development of mesoporous silica nanoparticles, forming a supramolecular structure that facilitates silica binding. The composition of this supramolecular framework leads to unconventional and variable pore structures. The scanning electron microscopy, transmission electron microscopy, Fourier-transform infrared spectroscopy, x-ray diffraction analysis, energy-dispersive X-ray spectroscopy, and Brunauer–Emmett–Teller analysis were used to characterize the quercetin-templated mesoporous silica nanoparticles and provide detailed insights into their morphology. The results from the viability test and antiviral assays demonstrated that quercetin-templated mesoporous silica nanoparticles are non-toxic and possess inhibitory and antiviral properties that are comparable to those of Oseltamivir, which served as a positive control. Quercetin served as a non-surfactant, neutral template in an ammonia and ethanol mixture, resulting in approximately spherical particles with monodisperse diameters of about 180 nanometers. These nanoparticles of mesoporous silica showed a concentration-dependent efficacy in inhibiting pathogenic microorganisms. In x-ray diffraction pattern for Mesoporous silica nanoparticles, a number of Bragg's reflections referring to the (111), (200), and (220) sets of lattice planes were detected, which can be described by the fundamental face center cubic structure of mesoporous silica nanostructures. Because of the smaller particle diameter impact and incomplete internal structure of the nanostructures, the intense peak at 2θ= 24 degrees demonstrated the silica peak, which reflected crystalline nature. According to calculations based on the Brunauer–Emmett–Teller method, the specific surface area of Quercetin-templated mesoporous silica nanoparticles was determined to be 55.227 cubic meters. Furthermore, the Barrett-Joyner-Halenda analysis provided measurements of the pore size at 24.312 nm and the pore volume at 0.336 square centimeters per gram, respectively. The study results outcomes demonstrated that quercetin forms a macromolecular scaffold that functions as a template for the formation of mesoporous silica nanoparticles. The irregular pore structure observed is attributed to the unique characteristics of quercetin. Using small-angle X-ray scattering, detailed information was obtained regarding the constituents and the porous nature of the resulting mesoporous silica nanoparticles. This study reveals innovative insights into the mechanisms by which the macromolecular structure of the template governs the dimensions of particles and the process of pore formation. The role of quercetin in the morphogenetic development of mesoporous silica nanoparticles has been thoroughly investigated. In addition, quercetin-templated mesoporous silica nanoparticles exhibited significant antioxidant properties, akin to butylated hydroxytoluene, and showed great potential for various clinical applications.

The reason for the lack of scientific researches in the field of positioning of natural areas and of course the necessity of combining these two areas to improve the level of positioning of natural areas is the need for a scientific method that can reanalyze and then compare and criticize and then evaluated the best results from the combination of fields in the studies. The purpose of this research was to evaluate the characteristics of the accumulated knowledge in the field of placemaking in terms of form, methodology and content.

Meta-analysis method was one of the tools needed to combine the tools needed to inform scientific decisions and policy-making, and on the other hand, it was a research study that systematically combined or integrated single-case results. It was used independently, using statistical methods to calculate a scientific work. The articles reviewed in this research were identified from the scientific database of Semantic Scholar in the period from 2018 to 2022. After reviewing and considering the quality of the output from the content point of view, 31 articles were reviewed and evaluated

There were more articles in the field of physical and human. The concept of placemaking based on the continuation of the value of natural areas referred to the preservation and sustainable exploitation of natural resources, biodiversity, and balance in ecosystems. Maintaining environmental balance, the economic value of these resources for income generation and employment, the social value of these areas for recreation and rest, and improving the quality of urban life and its environmental value were very valuable for preserving the environment of other creatures and protecting the natural environment.

There was a strong significant relationship between subject classification and theoretical approach. Place-making in nature has also a significant focus on the human-centered field, natural areas, sustainability and social health.

In the last three decades, especially in the last few years, the Supreme Leader has addressed the officials of the Islamic Republic of Iran in many meetings and statements and tried to explain the expectations and characteristics of the country's officials in order to achieve the desired responsibility. To depict the progress and excellence of the country, in this regard, perhaps the most important and comprehensive document is the statement of the second step of the Islamic Revolution. The aim of this study is to extract the components of responsibility in the system c. AA is based on the idea of the Supreme Leader and is formed using the data-based research method. The statistical population is dedicated to the full text of the second step of the Islamic Revolution of Iran and the sample size includes parts of the statement in which the Supreme Leader recommends or demands the officials or the youth in order to be held accountable. The method of data collection, library and research tools is filing. 254 attributes (data) were extracted for accountability. The results of three-stage open, axial and selective coding led to the extraction of 63 concepts, 27 components and 4 dimensions, respectively. Findings show that in order to be responsible at the level of the Islamic Revolution, one must focus on the four basic components of "individual needs of officials", "responsibility demands of officials", "individual needs of youth" and "responsibility demands of Youth" was focused. Also, the Supreme Leader's view in delegating responsibility is to emphasize the use of the youth and a function of the degree of adherence to religious, revolutionary and national rituals and values, moving on the basis of central justice and striving to ensure the security of the people and the country.

In the study and research of a literary text, the accuracy and authenticity of the text is more important and thought-provoking than anything else. Forouzanfar, Mojtaba Minavi, Shafiee Kadkani and Tawfiq Sobhani have already done valuable research on the correction and authenticity of the manuscripts of the Supreme Court. The Great Divan of Forouzanfar has already been more reliable in terms of correction than other works; However, as Minavi and Shafi'i Kadkani have pointed out, Forouzanfar's corrected Divan-e Kabir has some problems in terms of method and correction, the re-correction of which is a requirement of the research field.

This article was a descriptive-analytical study.

During the re-correction of Divan-e Kabir, the author encountered several lyric poems that differed from the lyric poems of printed divans in terms of vertical structure and number of bits; Even in some cases a considerable number of bits of printed divans; Among them was Forouzanfar's corrected court. The author considers these forms due to the corrected neglect of a stylistic feature of Rumi's sonnets. Therefore, in this study, by examining and analyzing phonetic stylistics, a unique stylistic feature has been introduced in a considerable number of sonnets, which ignoring this stylistic feature causes the verses to be split and far away, and in some cases some of the verses are removed.

The author's claim is that a number of lyric poems of Divan-e Kabir have been divided into authentic versions regardless of their specific style and manner of writing, and their semantic and structural entanglement has been lost. Therefore, first of all, these sonnets have been studied from the point of view of etymology and the result of studying the etymology of these sonnets is mentioned in the following article entitled: Then the two sonnets are brought together and finally in the study of the stylistics of these sonnets, the phonetic and typological layer of the sonnets and to some extent the coherence of the verses are studied. Then it is concluded that due to stylistic, typographical, structural and semantic reasons, the separation of these sonnets in the existing printed divans from Shams sonnets is incorrect and the juxtaposition of these verses helps to better understand the poem. In addition, some verses of the same sonnets have been omitted from the Divan of corrected by Master Forouzanfar during the correction mentioned in this article, verses whose authenticity is also confirmed by a valid manuscript.

Sanāyī’s Sīr al-Ibād Ila al-Ma’ād and Attār’s Musībat Nāmih are among the most important spiritual travelogues. There are similarities and differences between these two works. The differences are rooted in Sanāyī’s life and thought and the impact of unspiritual poems upon him. Indeed, Sanāyī is the poet of Taqhīq genre of poetry and Sīr al-Ibād is not completely mystical either. Additionally, Sanāyī is a pioneer in this domain, therefore, in the course of time, mystical language and thought have developed and have reached the acme of their growth in Attār’s travel account. In this article a general view of spiritual journey and its motivations and challenges are presented by providing an overview of similarities and differences between these two works. The differences are: 1. Structural differences, 2. Dual symbolism, 3. Different spaces. The similarities are: 1.Stages of creation, 2.Complaining about the world, 3.Return to the origin, 4.The wayfarer and the old sage, 5.The style of conversation, 6.The destination of the journey. The review of the similarities between spiritual journeys represents the general specifications of such works and puts them forth as motifs in mystical literature.
