Stock market forecasting is one of the most interesting research areas for many professionals and researchers. Economic conditions, investor sentiment, current events, future guidance, and a variety of other factors have an impact on the stock market. Since the stock market changes swiftly from time to time, it might be tough for a user or investor to keep up with the shifting trend. Combining sentiment analysis with a machine learning model, a solution to this problem has been introduced. Sentiment analysis is a text mining procedure that has one of the most important uses in analysing user reviews and evaluating the overall sentiment of a piece of text. The purpose of this research work is to create a machine learning model that takes recent tweets from the Twitter API and categorises each message as positive, bad, or neutral. Later, the impact of the person who wrote the tweet is also considered while predicting the trend. The parameters such as the total number of followers, the emotion of each comment on each post of selected stock, the number of likes and retweets are considered. An overview of the selected stock’s potential will be given to the user as the output.
This research will be useful for businessmen and people with enthusiasm for the stock market. The research will provide insights and intelligence to help make profitable decisions. False positives during sentiment analysis is a major concern in this domain. The team is focused on improving the existing approaches with better methods to identify false positives.
The Department of Economics of SRM University-AP, Andhra Pradesh, conducted a Panel Discussion on February 09, 2022, for the much needed and relevant in-depth analysis of the Union Budget proposed by the Finance Minister in the parliament on February 01, 2022.
Professor Bandi Kamaiah was the moderator of the event, and Dr Anandarao Suvvari, the faculty coordinator of the Department of Economics in the University, organised this discussion, inviting four eminent public finance economists of India, Prof N R Bhanu Murthy, Vice-Chancellor, BASE University, Bengaluru; Prof K R Shanmugam, Director, Madras School of Economics, Chennai; Prof K Gayathri, Professor, Institute for Social and Economic Change (ISEC), Bengaluru; Dr Shri Hari Naidu, Economist, National Institute of Public Finance and Policy (NIPFP), New Delhi. The co-convenors of the event were Dr Ghanshyam Pandey, Dr Manzoor Hassan Malik, Dr Kamal Sai Erra, Dr Hari Venkatesh from the Department of Economics SRM-AP.
The discussion started with a brief overview and essence of the Union budget by Dr Anandarao Suvvari, followed by Prof Bandi Kamaiah. Then first panellist Prof N R Bhanu Murthy, who our Indian Finance Minister also quoted, spoke about how the current budget is a continuation of the previous budget and emphasised more on the capital expenditure, which is the route to growth. He highlighted that the government should bring efficiency in public expenditure and expressed that the public policymakers side-lined the public debt number to GDP ratio at both central and state levels. An issue identified by Prof Murthy was bringing in many commodities under the customs tariff line and how doing this will have a negative impact on the exports. Further, he mentioned the ignorance towards the health and education sectors by a reduction in the allocation of expenditure for the same.
The second panellist Prof K R Shanmugam, gave a very detailed look at the budget, sector by sector, pointing out the benefits and the concerns related to each of them. He gave us a brief look at how the Indian economy has been doing for the past few years and gave an analysis taking this into consideration and stated that the budget had provided necessary fiscal stimuli through an increase in capital expenditure for the revival of the economy.
The third panellist Prof K Gayathri highlighted the philosophy of policy implications of budget and the need for a continuous process for analysing it. She also focused on the need for scientificity for estimates and the need for a sustainable approach for the budget. She pointed out that the current budget was future-looking in line with the vision for India 100 and that it put thorough emphasis on capacity building inclusive development by involving all stakeholders and modern infrastructure while expressing concern over effective implementation of policies.
The final panellist, Dr Shri Hari Naidu, discussed the revenue side of the budget thoroughly while focusing on the new taxation regime, other and legitimising crypto assets and digital Indian currency. In addition to this, Dr Naidu commented on the budget that the tax GDP ratio has been stagnant for the past two decades also, it has not been addressed in the budget, and despite the fact that there were a lot of tax reforms, the tax bases needed to be expanded.
After individual reviews by the panellists, questions posed by the students and the co-convenors were answered, followed by an interactive and engaging discussion among panellists, moderator, convenor and co-convenors on various issues spanning from the way of analysing the budget, trade-offs between debt and capital expenditure, debt sustainability, control mechanisms, the process of allocation, outcome evaluation or impact of the budget and the need for reality and effectiveness of planned budget on the ground level.
The session, after a thorough discussion on the union budget, was concluded by a vote of thanks proposed by Asst. Prof. Dr Hari Venkatesh to the esteemed panellists, moderator, convenor, co-convenors and all the people who made this session successful for contributing their precious time and valued efforts.

Dr Nimai Mishra, Assistant Professor, Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group comprising of students pursuing PhD under his supervision, Ms VG Vasavi Dutt, Mr Syed Akhil, Mr Rahul Singh, and Mr Manoj Paalabathuni have published a research article titled “High-Quality CsPbX3 (X = Cl, Br, or I) Perovskite Nanocrystals Using Ascorbic Acid Post-Treatment: Implications for Light-Emitting Applications” in the Journal “ACS Applied Nano Materials” (published by The American Chemical Society) having an impact factor of ~5.1.
Cesium lead halide perovskite nanocrystals (CsPbX3 PNCs) have been the flourishing area of research in the field of photovoltaic and optoelectronic applications because of their excellent optical and electronic properties. However, they suffer from low stability and deterioration of photoluminescence (PL) properties post-synthesis. One of the ways to minimize the surface defects in the surface treatment with suitable ligands is to achieve the PNCs with superior PL properties for light-emitting applications.
In this article, Dr Mishra’s research group addressed the issue of stability in PNCs. We demonstrate to achieve high photoluminescence and stability of CsPbX3 PNCs by incorporating ascorbic acid via post-treatment as a new capping ligand that is abundantly available. Upon addition of ascorbic acid as surface passivation ligand into the oleic acid/oleylamine system to get near-unity photoluminescence quantum yield (PLQY) of CsPbBr3, CsPb(Br/I)3, and for CsPbI3 perovskite NCs. Maintaining stability has become the hotspot of research in this field. Hence, as-a-proof of concept, the stability studies of PNCs in ambient conditions, under continuous UV irradiation, and PL with temperature variations are put forth here. The stability enhancement with post-treatment of ascorbic acid is highly reproducible as we tested for four batches of samples.
Despite the significant advancements of PNCs, there is a challenge afflicting the stability of CsPbI3 PNCs. They are thermodynamically unstable and undergo a non-perovskite phase (δ-phase) transition at room temperature. Many efforts have been reported in the stabilization of iodide perovskite NCs by critically passivating PNCs and applying them for optoelectronics and photovoltaics. On the other hand, mixed halide perovskites like CsPbBrI2 which are relatively stable than CsPbI3 PNCs are a better choice for device applications. But, photo-induced halide segregation is unavoidable which in turn again limit their usage in practical applications. In this manuscript, we demonstrated that the ultra-stable iodide-based PNCs can be achieved by simple and facile surface treatment with ascorbic acid.
The PL intensity of untreated and ascorbic acid-treated PNCs is recorded for 42 days since the date of synthesis. The measurements are carried out for 4 different batches of samples to ensure reproducibility. It is found that the PL intensity is deteriorating rapidly for untreated PNCs while the PL intensity is largely maintained for ascorbic acid treated PNCs. Nearly ̴72% of the initial PL intensity is maintained even after 42 days for the ascorbic acid-treated CsPbBr3 PNCs while the PL intensity is dropped to 24% for untreated PNCs. Ascorbic acid treated CsPbBrI2 PNCs exhibited exceptional ambient stability where ̴69% of the initial PL intensity is maintained after 42 days while the PL of untreated CsPbBrI2 PNCs is degraded rapidly within 2 weeks from the date of synthesis. Moreover, the PL stability of CsPbI3 PNCs is high for ascorbic acid-treated samples even after 55 days while the PL has deteriorated within 4 days for untreated CsPbI3 PNCs. The PL of untreated CsPbI3 PNCs is completely lost in the first 4 hours of UV illumination while ̴ 76.7% remnant PL is observed for ascorbic acid-treated CsPbI3 PNCs. We believe the stabilization of CsPbX3 PNCs of different halide compositions via simple surface treatment with ascorbic acid could form a basis for futuristic light-emitting applications.

Mr Chandra S Bhatt, a PhD Scholar (CSIR-JRF) working under the guidance of Dr Anil K Suresh, Associate Professor, Department of Biological Sciences, has won the Best Oral Presentation Award at the International Conference on “Novel Materials and Technologies for Energy Applications,” organised by BITS Pilani-Hyderabad, on February 18-19, 2022. Prof Ashutosh Sharma, Former DST Secretary & Institute Chair Professor, IIT Kanpur, was the Chief Guest of the Conference.
Mr Bhatt’s project aims to develop the best out of waste, which is practically demonstrated by synthesising gold nanostructured eggshell-based supported catalyst. Besides this novel strategy, the megacatalyst is implemented in the real-time degradations of organic and sewage dyes that are harmful to the environment and hydrogenation of nitroarenes at gram-scale (precursors for various pharmaceutical ingredients). Our rationale, naturally created, stable, reusable, hand-removable, resilient catalyst developed from left-over food waste trounces the majority of the existing challenges while utilising nano-based catalysts for heterogeneous catalysis.
With this innovation, Mr Bhatt aims to demonstrate pilot-scale (100-1000 litre) batch catalytic reactions for real-time textile sewage dye detoxification and gram scale hydrogenation of pharma-precursor for the production of acetaminophen, as a step of validation for immediate technology transfer and commercialisation for both environmental remediation and active pharmaceutical ingredients (API’s).
