    Due to its unique structural, physical properties (viz: higher mobility, electrical and thermal conductivity, higher mechanical strength, optical transmittance etc.) and chemical properties like easy functionalization and dispersion etc. the interest towards Graphene and its compounds going on increasing day to day. Here we are reporting the synthesis of Graphene using an efficient and simple method under microwave irradiation. Natural graphite and expected graphene were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Raman spectroscopy. In microwave irradiated expansion, high quality graphene was prepared. . This method is facile, inexpensive, and produces usable results. Extensive characterizations showed that the as-prepared materials consisted of creased, few-layer thick and electronically conductive graphitic sheets

    This research aims to examine how semiotic resources might be used to improve educational attainment, particularly for students in rural India. The fields of education, information, and communication have all benefited greatly from the new forms assumed by technology. Some groups of people continue to live on the periphery, oblivious to advances in literacy and technology, even while the rest of the globe rapidly modernizes. Children in rural communities are disadvantaged economically, socially, and academically. Their mental health is impacted by this. The quality of education has improved steadily in metropolitan areas, making it possible for more and more young people to benefit from it and mold their personalities in a positive direction. Teaching kids is much more than just helping them memorize facts and ace tests. They need this so they can plan for future. These youngsters may be taught utilizing a variety of semiotic tools to ensure that they fully grasp the language and the ideas being presented to them. Language, body language, and facial expressions are all examples of semiotic resources that may be used in conversation. This has far-reaching implications for how we educate the next generation. This research illustrates how these semiotic resources might be included into educational settings to improve the English language teaching proces

    Installations from Privilege to Survival: Emergence and Evolution of Dalit Voice on Instagram Accounts

    Growth of New Media has paved way for abundant possibility to articulate marginal voices. It is the emergence of social networking services that aids all the subaltern expressions to visualize their concerns on divergent virtual platforms. Visibility is the only path through which they can present their own underprivileged problems of discrimination and sense of identity. Ten years have passed since Instagram released its initial operations as a photo and video sharing space, and now the service witnesses a gradual shift of content creations. The proposed research paper traces the evolution of Instagram from a content-based perspective, arguing that the service has become a realm of survival as far as some communities are concerned drastically moving away from the privileged shutterbugs. It has the efficiency to advocate Dalit voice through multiple interactions. The paper attempts to analyse the Instagram accounts of Dalit Desk and The Blue Club foregrounding how the issues of caste atrocities in India are being mediated without the support of conventional media. The intervention of Instagram is perceived of two types in a structural approach; the first type being informative and persuasive for the common users where the second type seems to be academic and intellectual aiming to create potential exchanges on Dalit discourses. The former method makes use of the strategy of posting images directly which are related to segregation meanwhile the latter depends on a series of academic interactions in video format. Though the approaches are structurally different, they thematically intersect at a single point of representation. Considering the advancement of New Media as an alternative stream for the oppressed, the paper interprets distinctive installations in the form of real-life photos, short videos, posters, and long interactive videos as instances of rendering unheard inputs
