- Bioinspired GO/Au nanocomposite synthesis November 28, 2022
Nanocomposites are the heterogeneous materials that are produced by the mixtures of polymers with inorganic solids that are multi-phased with two or three dimensions of less than 100 nanometers (nm). Nanocomposites offer advanced technologies in enhancing several industrial sectors like automobile, construction, electronics and electrical, food packaging, and technology transfer, yet its sustainable and environment-friendly nature provides a great deal for mankind. Dr Imran Uddin, Post Doctoral fellow, Department of Physics, has published a paper titled “Bioinspired GO/Au nanocomposite synthesis: Characteristics and use as a high-performance dielectric material in nanoelectronics” in the South African Journal of Botany, having an impact factor of 3.11. The paper demonstrated that GO-based materials are better constituents for nanocomposite synthesis and facilitate in enhancing the performance of electrical devices and energy storage systems.
A bioinspired method was used to synthesise a graphene oxide (GO) based noble metal (Au) nanocomposite (GO/Au nanocomposite) using chemically exfoliated graphene oxide as the base matrix and gold (Au) nanoparticles. GO’s structural properties and morphology and the GO/Au nanocomposite were determined using XRD, TEM, SEM, EDAX, FTIR, and TGA analysis. LCR analysis was used to characterise the electrical characteristics of GO dielectric features as a function of frequency. The dielectric permittivity and electrical conductivity of GO were very frequency-driven. The results demonstrated that GO has direct current and Correlated Barrier Hopping conductivity processes in the low and high-frequency bands. The dielectric constant of the GO/Au nanocomposite shows that the bioinspired approach includes organic macromolecules capable of modest GO reduction and so modifying the C/O ratio, resulting in an enhancement in the matrix’s dielectric characteristics. This work shows that GO-based materials can be used to scale up high-performance electronic devices, as well as electrical and energy storage systems.
Explanation of the research in layperson’s terms
Energy consumption has increased multifold over the past few years. With increased consumption, the need for energy production and storage has become a pressing priority in the current generation. Dr Imran Uddin’s work aims to propose an idea to synthesise a mixture of two energy-storing materials (gold and carbon) at room temperature. Keeping in view the mentioned aim, he has used plant seeds to create this energy-storing mixture, also known as dielectric material in scientific terms. Through various analyses, he has noticed that this material is able to store electric energy at a lower frequency than the parent material. The superiority of this material comes into play in that when it expires, it can be easily disposed of without creating pollution, which goes hand in hand with the ultimate aim to develop sustainable energy-storing devices.
Dr Imran Uddin has mentioned the practical implication of the groundbreaking research. Capacitors are electronic devices that store electric energy in the form of charges. When a capacitor is linked to a charging circuit, it can store electric energy and release that stored energy when attached to an external circuit (like cars, fans, nuclear weapons, etc.), allowing it to be used as a temporary battery. Moreover, the synthetic GO/Au nanocomposite has the potential to be used as a capacitor material in biomedical applications (defibrillators, blood gas analyzers, pacemakers, biomedicines, etc.), as well as other fields where non-toxicity is essential.
The future prospects of Dr Imran Uddin’s research view an ambitious plan to manufacture more materials at room temperature using the green synthesis root. He also intends to investigate the electrochemical characteristics of environmentally benign materials in the field of electrochemical energy storage, such as supercapacitors and batteries.

- Novel antenna-duplexer for off-body communication November 28, 2022
With the recent advancements in modern wireless body area network (WBAN) communication, the demand for compact low-profile wireless computing devices has witnessed a vast increase. Consequently, the antennas which play a critical role in this network are developed with different polarization in distinct frequency bands so as to maintain better reliability of communication links. Dr Divya Chaturvedi, Assistant Professor, Department of Electronics and Communication Engineering, has published a paper titled, “A Dual-Band Dual-Polarized SIW Cavity-Backed Antenna-Duplexer for Off-body Communication” as first author in the Q1 Journal AEJ – Alexandria Engineering Journal having an impact factor of 6.77. The paper discusses the self-duplexing antennas, offering two channels for concurrent transmission and reception, leading to a simple and compact transceiver.
A novel dual-band, dual-polarized antenna-duplexer scheme is intended to be used for WLAN 802.11a and ISM band applications using Substrate Integrated Waveguide (SIW) Technology. The antenna consists of two planar SIW cavities of different dimensions where a smaller sized diamond- shaped cavity is inserted inside the larger rectangular cavity to share the common aperture area. The diamond-ring shaped slots are etched in each cavity for radiation. The larger diamond ring slot is excited with a microstrip feedline to operate at 5.2 GHz while the smaller slot is excited with a coaxial probe to operate at 5.8 GHz. The antenna produces linear polarization at 5.2 GHz (5.1–5.3 GHz) due to the merging of TE 110 and TE 120 cavity modes while circular polarization around 5.8 GHz due to orthogonally excited TM100 and TM010 modes (5.68–5.95 GHz). The slots are excited in an orthogonal fashion to maintain a better decoupling between the ports (i.e. –23 dB). The performance of the antenna has been verified in free space as well as in the vicinity of the human body. The antenna offers the gain of 6.2 dBi /6.6 dBi in free space and 5.8 dBi / 6.4 dBi on-body at lower-/ higher frequency-bands, respectively. Also, the specific absorption rate (SAR) is obtained < 0.245 W/Kg for 0.5 W input power averaged over 10 mW/g mass of the tissue. The proposed design is a low-profile, compact single-layered design, which is a suitable option for off-body communication.
Explanation of the research in layperson’s terms
- This antenna can operate in dual radio frequency bands at 5.2 GHz and 5.8 GHz respectively.
- The antenna can be used in the medical instrument to make it wire-free.
- The antenna is compact in size, thus can be accommodated in a small space.
- The antenna can operate simultaneously at both the frequency bands, thus at the same time it can help in forming links with another on-body antenna and makes the link with Wi-Fi.
- The antenna is validated in terms of Specific absorption rate, hence it is safe to use on the human body.
The paper further expounds on the social implication of this innovative research. Dr Chaturvedi explains that the antenna, being dual-band and dual-polarized, can function as a transceiver circuit. Due to different polarization, it can operate in both the frequency bands simultaneously without affecting the performance. In the first frequency band at 5.2 GHz, it can link with Wi-Fi and in the second frequency band at 5.8 GHz, it is able to communicate with antennas placed in other medical instruments which are used in the vicinity of the human body.

- Classification of brain tumours using fine tuned ensemble of ViTs November 11, 2022
Primary brain tumours make up less than 2% of cancers and statistically occur in around 250,000 people a year globally. Medical resonance imaging (MRI) plays a pivotal role in the diagnosis of brain tumours and advanced imaging techniques can precisely detect brain tumours. On this note, Dr Sudhakar Tummala, Assistant Professor, Department of Electronics and Computer Engineering, has published a paper titled, “Classification of Brain Tumour from Magnetic Resonance Imaging using Vision Transformers Ensembling” in the journal Current Oncology having an impact factor of 3.1. The paper highlights the pioneering breakthrough made in the development of vision transformers (ViT) in enhancing MRI for efficient classification of brain tumours, thus reducing the burden on radiologists.
Abstract of the paper
The automated classification of brain tumours plays an important role in supporting radiologists in decision making. Recently, vision transformer (ViT)-based deep neural network architectures have gained attention in the computer vision research domain owing to the tremendous success of transformer models in natural language processing. Hence, in this study, the ability of an ensemble of standard ViT models for the diagnosis of brain tumours from T1-weighted (T1w) magnetic resonance imaging (MRI) is investigated. Pretrained and fine tuned ViT models (B/16, B/32, L/16, and L/32) on ImageNet were adopted for the classification task. A brain tumour dataset from figshare, consisting of 3064 T1w contrast-enhanced (CE) MRI slices with meningiomas, gliomas, and pituitary tumours, was used for the cross-validation and testing of the ensemble ViT model’s ability to perform a three-class classification task. The best individual model was L/32, with an overall test accuracy of 98.2% at 384 × 384 resolution. The ensemble of all four ViT models demonstrated an overall testing accuracy of 98.7% at the same resolution, outperforming individual model’s ability at both resolutions and their ensemble at 224 × 224 resolution. In conclusion, an ensemble of ViT models could be deployed for the computer-aided diagnosis of brain tumours based on T1w CE MRI, leading to radiologist relief.
A brief summary of the research in layperson’s terms
Brain tumours (BTs) are characterised by the abnormal growth of neural and glial cells. BTs causes several medical conditions, including the loss of sensation, hearing and vision problems, headaches, nausea, and seizures. There exist several types of brain tumours, and the most prevalent cases include meningiomas (originate from the membrane surrounding the brain), which are non-cancerous; gliomas (start from glial cells and the spinal cord); and glioblastomas (grow from the brain), which are cancerous. Sometimes, cancer can spread from other parts of the body, which is called brain metastasis. A pituitary tumour is another type of brain tumour that develops in the pituitary gland in the brain, and this gland primarily regulates other glands in the body. Magnetic resonance imaging (MRI) is a versatile imaging method that enables one to noninvasively visualise inside the body, and is in extensive use in the field of neuroimaging.
There exist several structural MRI protocols to visualise inside the brain, but the prime modalities include T1-weighted (T1w), T2-weighted, and T1w contrast-enhanced (CE) MRI. BTs appear with altered pixel intensity contrasts in structural MRI images compared with neighbouring normal tissues, enabling clinical radiologists to diagnose them. Several previous studies have attempted to automatically classify brain tumours using MRI images, starting with traditional machine learning classifiers, such as support vector machines (SVMs), k-nearest-neighbour (kNN), and Random Forest, from hand-crafted features of MRI slices. With the rise of convolutional neural network (CNN) deep learning model architectures since 2012, in addition to emerging advanced computational resources, such as GPUs and TPUs, during the past decade, several methods have been proposed for the classification of brain tumours based on the finetuning of the existing state-of-the-art CNN models, such as AlexNet, VGG16, ResNets, Inception, DenseNets, and Xception, which had already been found to be successful for various computer vision tasks.
Despite the tremendous success of CNNs, they generally have inductive biases, i.e., the translation equivariance of the local receptive field. Due to these inductive biases, CNN models have issues when learning long-range information; moreover, data augmentation is generally required for CNNs to improve their performance due to their dependency on local pixel variations during learning.Therefore, in this work, the ability of pretrained and fine tuned ViT models, both individually and in an ensemble manner, is evaluated for the classification of meningiomas, gliomas, and pituitary tumours from T1w CE MRI at both 224 × 224 and 384 × 384 image resolutions.
Dr Sudhakar Tummala has mentioned the social implications of the research by expounding that the computer-aided diagnosis of brain tumours from T1w CE MRI using an ensemble of fine tuned ViT models can be an alternative to manual diagnoses, thereby reducing the burden on clinical radiologists. He also explains the future prospects of his research, which is to add explainability to the ensemble model predictions and to develop methods for precise contouring of tumour boundaries.

- The finale of the 88th Annual Meeting of Indian Academy of Sciences at SRM University- AP November 7, 2022
The three-day-long 88th Annual Meeting of the Indian Academy of Sciences came to an end at SRM University- AP on November 06, 2022. On the final day of the Meeting, Dr Swapan K Ghosh, University of Mumbai, chaired the first set of Lectures by Fellows/Associates Dr Prabhat Mandal, SN Bose National Centre for Basic Sciences, Kolkata; Dr Jitendra K Bera, IIT, Kanpur and Dr P Sreenivas, University of Hyderabad, were the speakers.
Dr Pranab Mandal spoke on the topic “A new paradigm for understanding solids”. He briefly discussed the conventional electronic states, which have been realised in the band theory of solids. The theoretical foundation and experimental realisation of topological electronic states in several condensed matter systems were also covered in the lecture.
“Water as a reactant in organometallic catalysis” was the topic presented by Dr Jitendra K Bera. The talk focused on the hydration of nitriles and alkynes, olefin oxygenation, alcohol oxidation to acid, and oxidative deamination of primary amines using water.
The last speaker of the session was Dr P Sreenivas, and he dealt with the topic “An advanced Ensemble Kalman Filter based ocean-atmospheric coupled data assimilation system and its impact in enhancing the Indian monsoon predictions”. He elaborated on how the new system incorporates theoretically advanced features of flow-dependency and ensemble-based analysis, and the predictions using the new system simulate the large-scale monsoon features and convection canters well and improves Indian Summer-monsoon-rainfall prediction skill with a gain of one month lead time.
Dr A Jayaraman, Bangalore University, Bengaluru, was the Chairperson to the lectures by Dr Suchana Taral, Pondicherry University, Puducherry; Dr Gobardhan Das, JNU, New Delhi and Dr Sneha Sagarkar, SP Pune University.
Dr Suchana Taral’s talk was on “Source-to-sink pathway of the Himalayan sediments: New evidence from the eastern Himalayan foreland”. In the lecture, she proposed a new model for the evolution of the eastern foreland basin, taking into account the hierarchical stratigraphic response to eustatic and tectonic forcing.
“Mycobacterium Tuberculosis programs mesenchymal stem cells to establish dormancy and persistence” was the topic presented by Dr Gobardhan Das. He explained that Tuberculosis treatment displays a biphasic bacterial clearance, in which the majority of bacteria clear within the first month of treatment, but residual bacteria remain nonresponsive to treatment and eventually may become resistant. Then he proceeded to show that Mycobacterium Tuberculosis was taken up by mesenchymal stem cells (MSCs), where it established dormancy and became highly nonresponsive to isoniazid, a major constituent of directly observed treatment short course (DOTS).
Dr Sneha Sagarkar talked about “Reward memory recall: Role of Glutamatergic Neurotransmission in the dentate gyrus”. She explained why the reward association process is critical for memory-guided decision-making that deteriorates mental illnesses such as binge eating disorders (BED), drug addiction, and schizophrenia.
