Abstract

Self-assembled nanostructures obtained from various functional π-conjugated organic molecules have been able to draw substantial interest due to their inherent optical properties, which are imperative for developing optoelectronic devices, multiple-color-emitting devices with color-tunable displays, and optical sensors. These π-conjugated molecules have proven their potential employment in various organic electronic applications. Therefore, the stimuli-responsive fabrication of these π-conjugated systems into a well-ordered assembly is extremely crucial to tuning their inherent optical properties for improved performance in organic electronic applications.

To this end, herein, we have designed and synthesized a functional π-conjugated molecule (TP) having phenanthrol [9,10-d] imidazole with terpyridine substitution at the 2 position and its corresponding metal complexes (TPZn and (TP)2Zn). By varying the polarity of the self-assembly medium, TP, TPZn, and (TP)2Zn are fabricated into well-ordered superstructures with morphological individualities. However, this medium polarity-induced self-assembly can tune the inherent optical properties of TP, TPZn, and (TP)2Zn and generate multiple fluorescence colors.

Particularly, this property makes them useful for organic electronic applications, which require adjustable luminescence output. More importantly, in a 10% aqueous-THF medium, TPZn exhibited H-type aggregation-induced white light emission and behaved as a single-component white light emitter. The experimentally obtained results of the solvent polarity-induced variation in optical properties as well as self-assembly patterns were further confirmed by theoretical investigation using density functional theory calculations. Furthermore, we investigated the I− V characteristics, both vertical and horizontal, using ITO and glass surfaces coated with TP, TPZn, and (TP)2Zn, respectively, and displayed maximum current density for the TPZn-coated surface with the order of measured current density TPZn > TP > (TP)2Zn.

This observed order of current density measurements was also supported by a direct band gap calculation associated with the frontier molecular orbitals using the Tauc plot. Hence, solvent polarity-induced self-assembly behavior with adjustable luminescence output and superior I−V characteristics of TPZn make it an exceptional candidate for organic electronic applications and electronic device fabrication.

Research Explanation

Our investigation is based on the electron transport characteristics of molecules (voltage vs. current), which allows us to ascertain the molecule’s conductive capacities. The Janis probe station, which has four gold tips total is the primary instrument utilized in this investigation. To investigate the properties of electron transport, two gold tips were used: one in contact with an aluminum electrode and the other with an ITO surface. The current measurements for a given voltage of given molecules have been studied using a source measuring unit.

Application

• Our research study can be applicable to predict the good electron and hole transport layers for the Organic Light Emitting Diode (OLED) application.
• Organic field effect transistor (OFET) applications.

Join us in celebrating their insightful contributions to the literary discourse, reflecting SRM AP’s commitment to advancing knowledge and fostering academic excellence.

Abstract

Premiered as a television web series on Amazon Prime Video on 8th March 2019, Made in Heaven (2019) simultaneously unmasks the hypocrisies and lies of the big fat Indian weddings and breaks the taboo of homosexuality. In consecutive nine episodes, the plots and the subplots are beaded together to initiate a sensory sensitization towards the hypocrisy of marriages and insensitive homophobia. Carefully analyzing postulates from theorists this short article attempts to decode the trouble, trauma, and pain encoded in messy lifestyles, marriages, and relationships characterizing and wielding the lives as well as the sexuality of the characters in the web series

Explanation in Layperson’s Terms

The research revolves around the concept of marriage in Indian society as well as homosexuality in the Indian Hindi web series Made in Heaven (2019). The research shows how the various episodes of the web series showcase different aspects of marriage and the actual reality behind the pomp and pleasure of high-profile weddings within society. On the other hand sexuality and sexual desire are often hidden and do not get proper channelization in a person’s life. The desire thus remains suppressed and results in crisis in many forms. There are other intertwined concerns such as the dowry system, social disparity, impotency, virginity, and sexual molestations which weave a meta-narrative on the popular medium and raise consciousness regarding how people should react to those hazards and behave accordingly.

Practical Implementation and Social Implications of the Research

The research involves practical aspects such as the dowry system, social disparity, impotency, virginity, and sexual molestations which are part of our social lives. Many people have to face such things in their day-to-day lives. This research brings out such realities of society while analyzing the mental condition and psychology behind these. Moreover, this research also shows marriage is an important decision in a person’s life, it should be made in terms of love and respect, not based upon money and social status. The research visits practical examples and revisits the laws to substantiate the arguments. Popular media such as web series is not just a form of entertainment, but it can be a medium for building awareness.

Dr Bikku, Assistant Professor, Department of Liberal Arts has presented a paper titled “Mobile Pastoralism and Conservation in the 21st Century: A Case Study from India” at the NIAS Conference on Belonging & Mobility, held at the Netherlands Institute for Advanced Study (NIAS), Amsterdam, Netherlands on October 18-20, 2023 (online).

Congratulations to Dr Bikku for this remarkable achievement. SRM AP immense pride in the success of its faculty and scholars and applauds their unwavering commitment to scientific excellence and societal impact!

Abstract

The study focuses on the struggle of nomadic pastoralists to continue their traditional occupation of raising livestock at different landscapes in the face of the shifting political ecology in India. Pastoralism is a traditional subsistence livelihood pattern that involves raising domestic animals in different pastures. For pastoralists to use continually shifting resources in a variety of ecological landscapes, mobility is an effective strategy. However, the current conservation approach has colonial roots and reinforces biodiversity conservation by establishing and enforcing protected areas in several countries around the globe. Scientific conservationists and states have often seen pastoralism responsible for environmental degradation and wildlife decline through over-grazing and resource competition, respectively. As a result, the customary rights of the various pastoralist groups have been denied inside and outside the protected areas.

The paper investigates the current global conflicts between pastoralism and conservation. It also emphasises the changing dimensions of mobile pastoralism and conservation policies in India. By challenging the conservationists’ and the state’s preconceived notions about pastoralism, the Raika mobile pastoralists of Rajasthan, India, provide sustainable pastoralism and nature conservation through evidence of the coexistence of pastoralism and multispecies.

The combat against HIV, the virus responsible for AIDS has witnessed consistent advancements and studies put forward by researchers in various fields. To identify a more intelligent and effective approach to combat HIV-1 and enhance the understanding of the workings of its treatments, Dr Koyel Chakravarty, Assistant Professor, Department of Mathematics has published a paper titled “Mathematical modelling of HIV-1 transcription inhibition: a comparative study between optimal control and impulsive approach” in the Q2 journal, Journal of Computational and Applied Mathematics.

Abstract

By adopting a proactive strategy, this study facilitates the interaction with human immunodeficiency virus type I (HIV-1), successfully navigating its sequential fusion stages. This approach enables efficient infiltration of the virus into a target CD4+T helper cell within the host organism, initiating the virus’s replication cycle. As a retrovirus, HIV-1 orchestrates the conversion of its single-stranded viral RNA genome into a more stable double-stranded DNA structure. The newly formed DNA integrates with the host cell’s genetic material, and the pro-viral DNA transforms into functional messenger RNA (mRNA) with the assistance of the host enzyme RNA polymerase II (Pol II).

The ongoing research focuses on constructing a meticulous mathematical framework using a system of nonlinear differential equations. The investigation aims to assess the impact of a Tat inhibitor on suppressing the transcriptional activity of HIV-1, treating it as an optimal control problem. The study also evaluates the Tat inhibitor’s efficacy as a potential therapeutic intervention for HIV-1 infection. Employing a one-dimensional impulsive differential equation model to determine the mathematically derived maximum concentration of the elongating complex (P2), the research considers the crucial aspect of optimal timing between successive dosages. A comparative analysis contrasts the effects of continuous dosing with impulse dosing of the Tat inhibitor, using numerical analysis to evaluate outcomes. The findings underscore the superior effectiveness of impulsive dosing over continuous dosing in inhibiting HIV-1 transcription. Visual representations of the model’s parameter sensitivities enhance understanding of the intricate physiological and biochemical processes within the system.

Dr Sayantan Thakur, Assistant Professor in the Department of Literature & Languages have published his research paper, ‘Vaishnava Philosophy and the Poetic Aesthetics: An Analysis of Jayadeva’s Gita Govindam‘ in Tattva: Journal of Philosophy, an esteemed EBSCO-indexed and UGC-CARE Listed Journal. Dr Thakur’s work embodies the spirit of academic rigor and philosophical inquiry. Join us in traversing the landscapes of wisdom, where intellect meets aesthetics, and knowledge transcends boundaries. Explore the rich tapestry of ideas that define SRM University-AP‘s commitment to intellectual excellence.

Abstract

Literature finds the best expression when literary aesthetics and philosophy run side by side. The former offers the external charm, while the latter inculcates the more profound implication with the aim of providing it with a superior stature and permanence. Jayadeva’s Gitagovindam, being a colossal work in the field of Vaishnava literature, does contain the brilliant juxtaposition of both. This article attempts to show how Jayadeva’s Gitagovindam, a colossal work in the field of Vaishnava literature, does contain the brilliant juxtaposition of both. On the one hand, like a typical lyrical poem, its melodic nature does have a soothing effect and on the other, the use of philosophy instils in it a greater depth and seriousness to uplift itself as a book of devotion and religious inspiration. Moreover, the importance of this Holy Scripture lies in the fact that it not only played a significant role in paving the way to form a new sect in the Vaishnava religion, known as ‘Gaudiya Vaishnavism’, but also showed the later Vaishnava lyricists the art of portraying in words the amorous love of Lord Krishna and Radha with compassion and tears.

Practical implementation and social implications of the research

Cultural Preservation: Understanding and analysing ancient texts like the Gitagovindam helps in preserving cultural and religious heritage. This research can contribute to the preservation and understanding of Vaishnava philosophy and its cultural significance.
Literary Understanding: Analysis of the text can provide insights into the interplay between philosophy and aesthetics in literature. It can be used as a tool for students, scholars, and enthusiasts to comprehend how profound thoughts are conveyed through art and literature.
Religious Studies: It will be valuable for religious scholars and practitioners, shedding light on the philosophical underpinnings of Vaishnavism. It can deepen the understanding of the religious sentiments associated with the worship of Lord Krishna.
Artistic Inspiration: By examining the poetic aesthetics the research might inspire contemporary artists, poets, and musicians in exploring similar thematic elements in their creations. It could lead to the creation of new artistic works that incorporate similar philosophical depth.
Community Understanding: Studies like mine can also bridge gaps in understanding between different communities by shedding light on the beliefs and values encapsulated in ancient texts. This understanding might foster better cultural appreciation and harmony.
Interdisciplinary Insights: The analysis might encourage interdisciplinary studies by merging literary analysis with philosophy, offering new avenues for exploration and collaboration between these fields.

Dr Soumyajyoti Biswas, Assistant Professor in the Department of Physics, along with his Doctoral Scholar, Mr Soumyaditya Das, have presented groundbreaking findings through their research work titled “Critical Scaling through Gini Index”. The research paper was featured in the prestigious Physical Review Letters, which has an impact factor of 9.161.

Abstract

In the systems showing critical behaviour, various response functions have a singularity at the critical point. Therefore, as the driving field is tuned toward its critical value, the response functions change drastically, typically diverging with universal critical exponents. In this Letter, we quantify the inequality of response functions with measures traditionally used in economics, namely by constructing a Lorenz curve and calculating the corresponding Gini index. The scaling of such a response function, when written in terms of the Gini index, shows singularity at a point that is at least as universal as the corresponding critical exponent. The critical scaling, therefore, becomes a single parameter fit, which is a considerable simplification from the usual form where the critical point and critical exponents are independent. We also show that another measure of inequality, the Kolkata index, crosses the Gini index at a point just prior to the critical point. Therefore, monitoring these two inequality indices for a system where the critical point is not known can produce a precursory signal for imminent criticality. This could be useful in many systems, including condensed matter, bio- and geophysics to atmospheric physics. The generality and numerical validity of the calculations are shown with the Monte Carlo simulations of the two-dimensional Ising model, site percolation on the square lattice, and the fibre bundle model of fracture.

Fig.1: Shows the crossing point of the Gini index and the Kolkata index prior to critical point for three different models (from left Ising model in 2d, site percolation in 2d and fiber bundle model of fracture) form both side of critical point.

Collaborations and Future Plans

This work essentially builds a framework for indicating imminent critical points for any system. Therefore, in situations where such knowledge is vital, for example, in the fracture of solids, the method is going to be highly useful in forecasting the failure point. We are in the process of working with our collaborators at the University of Barcelona to experimentally verifying our methods for the compressive failure of porous samples. This is a significant first step towards opening new pathways in forecasting fracture points in disordered materials that could have an impact on laboratory-scale fractures to large constructions and eventually to earthquakes.

We wish the teacher-student duo many more fulfilling and enriching research endeavours in future!
