Sri Sathya Sai Institute of Higher Learning Celebrates its 40th Annual Convocation
Puttaparthi, 22 November 2021:
Sri Sathya Sai Institute of Higher Learning (SSSIHL) (Deemed to be University) held its 40th Annual Convocation in the Poornachandra Auditorium, Prasanthi Nilayam, Andhra Pradesh in the Divine Presence on 22 November 2021 at 9:10 a.m.
The grand ceremony saw the Honourable Chancellor, Sri K Chakravarthi, IAS (Retd.), admit candidates to their degrees.
SSSIHL was honoured to have the Chief Justice of India, Hon’ble Mr. Justice N. V. Ramana, as the chief guest for the event.
Born in an agricultural family in the Krishna District of Andhra Pradesh, Justice N.V Ramana enrolled as an Advocate in 1983 and practiced in the High Court of Andhra Pradesh, Central and Andhra Pradesh Administrative Tribunals, and the Supreme Court of India in Civil, Criminal, Constitutional, Labour, Service, and Election matters. He has specialized in Constitutional, Criminal, Service, and Inter-State River laws. Before being Elevated as a Judge, Supreme Court of India on 17.02.2014, he held several prominent positions including the Chief Justice of the Delhi High Court, Acting Chief Justice of Andhra Pradesh High Court, and a permanent Judge of the Andhra Pradesh High Court, in addition to the role of the Additional Advocate General of Andhra Pradesh. Justice Ramana was appointed as the 48th Chief Justice of India by the President of India on 6 April 2021. He took Oath on 24 April 2021.
The event began at 9:10 a.m. when the Chief Guest along with the Chancellor, Vice-Chancellor, Registrar, Controller of Examinations, Members of the Sri Sathya Sai Institute of Higher Learning Trust, the Board of Management, Academic Council, Deans, HoDs and other distinguished delegates, entered the Poornachandra Auditorium in Prasanthi Nilayam with the Registrar of the University carrying the ceremonial mace.
Following the invocatory Veda chanting from Taittriya Upanishad, the Vice-Chancellor, Prof. (Dr.) C B Sanjeevi prayed to the Revered Founder Chancellor to declare the convocation open. The Convocation was then declared open in the Divine voice of Bhagawan Sri Sathya Sai Baba.
Speaking on the occasion, the Vice- Chancellor gave a glimpse into the high-quality research for societal benefit done leveraging the world-class Central Research Instruments Facility (CRIF) and the Central Research Laboratory (CRL) at SSSIHL. He said it was a proud moment for SSSIHL, when the Indian Council of Medical Research (ICMR), approved the ‘SAIC-19 AgKit’ Rapid Antigen Test Kit for COVID-19 in February 2021, that was developed by SSSIHL, making us the only academic institution to have received the approval in that category. Patented in the name of SSSIHL, the ‘SAIC-19 AgKit’ is now aiming for US-FDA approval, he added. On the Innovation side, he said SSSIHL is pursuing over 30 projects with ‘Technology Readiness Level’ of 5 or more, in (a) Healthcare, (b) critical Public goods & services, (c) Food & Nutrition, (d) Cyber Security applications and (e) Insurance.
The Vice-Chancellor then highlighted various international collaborative research projects with bilateral funding opportunities under Indo-Swedish, Indo-Italian, Indo-Australian, Indo-Canadian, and Indo-US programs. He also reported two such recent collaborations, one with Uppsala University in Sweden and the other with Macquarie University, Australia and University of Maryland Baltimore County, USA. He then went on to congratulate the faculty and students for the various academic achievements won by them for their work in their respective field of study.
He concluded by fondly remembering the Revered Founder Chancellor Bhagawan Sri Sathya Sai Baba’s prophetic statement “The seed has been planted; it will sprout and spread, heavy with fruits, providing shade, security and sustenance to all”, from His Discourse during the inauguration of the College Building of the Sri Sathya Sai Institute of Higher Learning, Anantapur Campus 50 year ago, praying that He continues to guide us to take His noble Mission to greater heights as envisioned by Him.
The convocation oath was then administered by the Vice-Chancellor, after which the Gold Medallists of the Institute were awarded by the Chief Justice of India, Hon’ble Justice N V Ramana. In addition to Gold Medallists, the doctoral research scholars were conferred their Ph.D. degrees by the Chancellor and given special mementos blessed by Founder Chancellor Bhagawan Sri Sathya Sai Baba.
The Chief Justice of India, Hon’ble Justice N V Ramana in his Convocation address to the students, said education is much more than academic learning, and that true education helps imbibe the moral values and virtues of humility, discipline, selflessness, compassion, tolerance, forgiveness, and mutual respect. And that it helps elevate our character and broaden our thinking, enabling us to take the right decision when faced with complex challenges in life. Students of SSSIHL are fortunate to have Baba’s philosophy enshrined at the centre of their curriculum which believes that the ‘End of Education is Character’.
SSSIHL he said was built around the concept of a modern Gurukula, where cutting edge modern education is being offered along with the essence of Indian Culture, values, and lifestyle is inculcated in the students ensuring all-round development, mental fortitude, and a sense of social responsibility, which he said was, unfortunately lacking in the modern education being offered today.
Exhorting students to look beyond their own needs, he emphasized on their responsibility towards enriching society, by propagating knowledge and empowering people and communities around them to usher in a progressive world free of conflicts and violence. He concluded by reminding the students of their pledge where they promised to support the cause of sound learning, humanity, morality, and spirituality and urged them to uphold their oath in life.
The graduates were then blessed with the Divine Benediction by our Revered Founder Chancellor, Bhagawan Sri Sathya Sai Baba Baba who addressed the students as ‘Emancipators and Patrons of education’. Baba then spoke on how true education can prepare a student for life, and not merely to earn a living. Likewise, the true meaning of ‘Educare’ imparted to students at SSSIHL He said was ‘to bring out that which is latent or hidden in us’ and asked the students to try to bring out the ‘Divine feelings’ hidden within and make it the second wheel of the chariot of life, the first being worldly education.
The event concluded with the National Anthem and Mangala Aarati.
As part of the 40th convocation, a Drama entitled “Wind Beneath My Wings” will also be streamed on the Prasanthi Mandir Live channel of YouTube, at 7pm later this evening. The Drama entitled- Wind Beneath My Wings is a story of a day in the life of a tiny bird that is all set to take its first leap of faith for a graceful flight unto a wonderful realization

Innovative Engineering of Sorets on Photonic Crystal to Augment Sensing Technologies
Dr. Sai Sathish Ramamurthy (STAR Lab, SSSIHL) in a trilateral collaboration with Dr. Chandramouli Subramaniam (Nanostructured Material Lab, IIT-Bombay) and Dr. Shivakiran Bhaktha (Photonic Systems Laboratory, IIT-Kharagpur) has published a new paper in Nanophotonics (Walter de Gruyter publication) demonstrating unusual ‘photoplasmonic’ effects (as they call it in the article) with the use of gold nano-assembly termed ‘sorets’ and Nd2O3 nanorods. The unavoidable losses in the gold nanoparticles are overcome with these functional metasurfaces in photonic crystal-coupled emission (PCCE) platform developed by the team in the year 2020, thereby demonstrating outstanding performance of the subject platform for several sensor applications.
Identifying the Issue
- Sensors are widely used in industrial processes, monitoring community well-being, homeland safety, criminalistics, environmental health supervision and point-of-care diagnostics
- Nanomaterials made of metals (generally called plasmonic materials) are throughout-the-world used in the evolution of sensor technology systematization. However, their accurate potential is beleaguered by inevitable inherent Ohmic losses that encumber the functional performance of any sensing platform
- Therefore, there is constant need for novel synthetic routes and advanced material platforms for global market sensor industries, using nanochemistry-based novel methods
Objective of the Research
- Ascertaining the ground elemental causes which leads to unproductive Ohmic losses in terms of basic physico-chemical aspects of the individual nano-constructs
- Discovering a frugal & viable technological solution to abate/preclude the Ohmic losses and recuperate the performance of gold nanomaterials, consequently demonstrating a translational approach to offer sensor-based industries with materials with grander efficiencies
- Refining the overall sensitivity and specificity of photoplasmonic sensor platform using cut-rate metal-dielectrics in comparison with cost intensive and hazardous nano-sensor techniques
Who should read this?
Anyone in industry, working directly or indirectly on advanced sensor technologies or sensing related know-hows including, security, reconnaissance, specialist (intensive) care units, environmental safety monitoring mechanisms, therapeutic technologies and disease diagnostics. Further this article will be extremely useful to researchers currently faced with the problem of ‘Losses’ in metamaterials dependent on plasmonic nanoparticles.
“Photoplasmonics”– A blossoming, rapid & realistic solution for the snags in biosensor technologies
- The novel nano-engineering strategies for diverse applications in optics and nano-bioengineering domains are discussed in this work
- In spite of copious electron densities of ≈ 5.9 × 1022 cm−3, excellent biocompatibility, structural tunability and utility in numerous biosensors, so far the quenching phenomenon in gold nanoparticles has remained an unescapable caveat
- Although sharp-edged nanostars and decorated nanohybrids have been explored in the past, the enhancement factor has been modest at 200-fold. The PCCE platform developed in this work with the use of gold sorets and high refractive index Nd2O3 ‘Huygens sources’ demonstrated unprecedented >1500-fold enhancement factor
Key Features and Benefits
- Use of judicious hybrid metal nano-assembly – dielectric nanorods assemblage.
- Experimental demonstration of suppressed quenching and >1500-fold PCCE enhancement.
- The multifold ‘gap-based antenna’ and ‘lightning-rod’ effects generated by the nano-assemblies and nanorods that sustain multitudinous hotspots catering to excellent sensitivity of PCCE platform
- The proposed hybrid methodology is useful in disease diagnostics for monitoring early stages of the disease and also aid in the fabrication of smart sensor chips for use in Point-of-Care (POC) devices
Impact
- The collective and coherent coupling between localized Mie and delocalized Bragg plasmons (of sorets), dielectric plasmons (of Nd2O3), highly confined & intense Bloch surface waves (of PCCE platform) aided in realization of dequenched, as well as amplified > 1500-fold enhancements at the photoplasmonic nanocavity interface, thereby addressing the quenching predicament
- The PCCE platform is expected to find immediate deployment for real-time monitoring of health and hazardous in environment. This study presents itself as a milestone to explore a plethora of exciting disruptive nano-engineering with the aid of different permutations and combinations of nanomaterials of different geometry and number, chosen from the Periodic Table. We anticipate the crucial role of machine learning and data science pertaining to materials properties in this regard.
- The proposed technology is a jumping-off point for sensor-based industrial establishments or market seeking such devices with augmented sensitivity. The high sensitivity aids in early disease diagnostics, ecological safety and bio-nano-engineering and related applications
- The rapid, cost-effective and simple plasmon mixing strategy used in the photoplasmonic platform with advanced nano-engineering are of immense benefit for low- and middle-income countries, in resource-limited settings and bottom of the pyramid.
