Better Kinetics with MXene-based Electrocatalysts in Fuel Cells
A cutting-edge research paper on MXene-based electrocatalysts for fuel cells has been published by Dr Lakhveer Singh of the Department of Environmental Sciences. In the journal of Advanced Materials Interfaces, Impact factor 6.14, his paper, titled “Recent Advances on MXene-Based Electrocatalysts toward Oxygen Reduction Reaction: A Focused Review”, has been published in collaboration with Dr S. G. Peera and Dr. T. G. Lee from the Department of Environmental Science and Engineering Keimyung University Daegu 42602, Republic of Korea.
Oxygen reduction reaction (ORR) takes place in the fuel cells. Improving the kinetics of the reaction would be a major step in improving the efficiency of the fuel cells. Extensive studies have been done to find cathode catalysts that are both highly active and also maintain stability in a corrosive environment. Recent research has been leaning towards 2D materials owing to the larger surface area they provide for catalyst dispersion. MXene-based catalysts have become popular due to their impressive electrical conductivity as well as their thermal and chemical stability.
A summary of Dr Singh’s paper:
MXene, a novel transition metal carbide and/or nitride based two-dimensional material has been gaining a considerable interest in the field of energy storage and conversion, due to their unique layered structure, electronic properties, and surface chemistry, that are beneficial for various electrochemical reactions. Most of the MXenes research done so far is in the field of supercapacitors, batteries, overall water splitting, and other catalytic applications. The research done on fuel cell cathodic oxygen reduction reaction (ORR) is scarce. There is a need for intensive review on Mxenes. Uniquely, this review article describes the ORR catalysis of MXene based catalysts both in theoretical and experimental view.
In future they plan to work on investigations on theoretical and computational screening to elucidate the ORR mechanism, stability, and strategies for improving the electrocatalytic activity of MXene catalysts; these studies can serve as a guide for experimentalists, especially for selecting optimal catalyst compositions.

Impact of Surface Chemistry on the Excited State Interactions of CsPbBr3
Dr Nimai Mishra, Assistant Professor, Department of Chemistry, SRM University-AP along with his team comprising of his PhD scholars Mr. Syed Akhil, Ms. V.G.Vasavi Dutt, and Mr Rahul Singh have published a research article titled “Surface-State-Mediated Interfacial Hole Transfer Dynamics Between CsPbBr3 Perovskite Nanocrystals and Phenothiazine Redox Couple” in The Journal of Physical Chemistry-C, published by The American Chemical Society with an impact factor of ~4.126.
Dr Mishra’s research interests lie in Semiconductor nanocrystals, Core/shell branched structures, Nanowires, Perovskite nanocrystals and Optoelectronic device fabrication. He studied the role of surface chemistry for improving excited state hole transfer from CsPbBr3 nanocrystals to an acceptor, potentially applicable for photocatalytic applications.
About the research:
Recently, caesium lead bromide (CsPbBr3) perovskite nanocrystals (PNCs) gained enormous attention for designing photocatalytic reactions because of their photocatalytic properties. But the surface chemistry of nanocrystals is often ignored which dictate the excited state interactions of these semiconductor nanocrystals with the charge shuttling redox-active molecules. In this work, we have explored the impact of CsPbBr3 perovskite nanocrystals with the three different surface chemistries on the excited state interactions with the standard hole acceptor phenothiazine molecule. From the steady PL-lifetime decay measurements we have calculated the photoinduced hole transfer (PHT). In the amine-free PNCs case, PHT is 6 times higher than the conventional amine capped ligands. Using the lifetime fast component (1) rate constants, we have calculated the hole transfer constant (kht) which is 3.942 × 108 s-1 and it is 4 times higher in amine-free ligands when compared with conventional amine ligands system.
According to Dr Nimai Mishra, the most important contribution of this research is that these results highlight the impact of surface chemistry on the excited state interactions of CsPbBr3 PNCs and conclude amine-free PNCs could be an ideal candidate for photocatalytic reactions.

Securing Online Payments made through Wearable Devices
Smart devices and Internet of Things (IoT) are growing in importance every day and so do our security concerns about using them for our financial transactions. As we carry the world with us through wearable technology, Dr Sriramulu Bojjagani, Assistant Professor, Department of Computer Science Engineering works towards making wearable devices more secure.
With a thriving interest in Cyber Security, Formal Verification Methods and Vulnerability Analysis and Penetration Testing, Dr Bojjagani has recently published his paper on “A Secure IoT-based Micro-payment Protocol for Wearable Devices” in Peer-to-Peer Networking and Applications (PPNA), Springer.DOI: 10.1007/s12083-021-01242-y
Abstract:
Wearable devices are one of the parts of the essential cost of goods sold (COGS) in the wheel of the Internet of things (IoT), contributing towards a potential impact in the finance and banking sectors. There is a need for lightweight cryptography mechanisms for IoT devices because these are resource constraints. This paper introduces a novel approach to an IoT-based micro-payment protocol in a wearable device’s environment. This payment model uses “elliptic curve integrated encryption scheme (ECIES)” for encryption and decryption of the communicating messages between various entities. The proposed protocol allows the customer to buy the goods using a wearable device and send the mobile application’s confidential payment information. The application creates a secure session between the customer, banks, and merchant. The static security analysis and informal security methods indicate that the proposed protocol is withstanding the various security vulnerabilities involved in mobile payments. For logical verification of the correctness of security properties using the formal way of “Burrows-Abadi-Needham (BAN)” logic confirms the proposed protocol’s accuracy. The practical simulation and validation using the Scyther and Tamarin tool ensure the absence of security attacks in our scheme. Finally, the performance analysis based on cryptography features and computational overhead of related approaches specify that the proposed micro-payment protocol for wearable devices is secure and efficient.
Architecture for wearable devices:
The architecture for wearable devices is shown in Fig. 1. It consists of six types of entities, such as Issuer bank (IB), acquirer bank (AB), payment gateway (PG), a certification authority (CA), mobile terminal, and wearable sensing devices. The person using various wearable devices such as a smartwatch, smart wristband, smart glass, etc. In the architecture, a wearable device is connected to the mobile terminal through NFC. An app is running on a mobile device. Wearable devices are resource constraints because they have limited computing capabilities regarding battery, display, storage, and processing compared to a mobile terminal (smartphone). Hence, NFC is used to pair the wearable device and mobile terminal for transmitting public messages. Before conducting any transaction with the merchant, the customer and merchant should register their mobile numbers with the bank.
Fig. 1. Architecture for wearable devices
The customer can place an order with the merchant using the following steps and the complete messages flow in the proposed protocol is shown shown in the Figure.
● The customer places an order for an item through a wearable device.
● The request is transferred to the mobile app. The mobile app verifies the user authentication.
● After a successful authentication request, the app forwarded the request to the issuing bank for payment verification.
● The customer also sends a payment request for a deduction of the amount from his/her issuing bank.
● Once the bank validates the customer data in terms of sufficient funds available and user’s integrity. The issuing bank routes the transaction to the payment gateway through a secure network.
● In this step, the payment gateway verified the customer payment order and transferred it to the acquiring bank.
● If all the verifications are successful, then the transaction amount is then debited from the issuing bank and credited to the merchants’ acquiring bank.
Application demonstration:
As we know, most wearable devices run the Android operating system. The proposed framework developed as an Android application package (APK) file run in an Android wearable emulator, but we have operated in the Samsung Galaxy Note-2 device due to limits of the screen device and lack of environment. First, it needs to install the APK file and start running the app. Before running the app, some points need to be considered, such as the following:
● The company voice gateway provided for the service of an SMS gateway connected to Xeon server and assigned us a shortcode 56677.
● The payment gateway switch is used to communicate with the customer and merchant bank accounts.
● Two mobile numbers are registered with the banks and telecom operations, and it is used for SMS service.
● The deployed decryption web application on the Xeon server.
● HTTPS connection is used between voice gateway and Xeon server established Indian financial network (INFINET) link between server and bank.
We have not mentioned all the screenshots for the app from starting the login and authentication phase, but the protocol requires the essential information only shown in the screenshot. We didn’t mention the banks considered for implementing the micro-payment protocol for security and reputation reasons.
The proposed protocol action is as follows:
Step 1: The customer x runs a wearable application to enter Wearable-id, mobile number, pin and amount and sends an encrypted message to the Xeon server via short-code 56677. To encrypt the message, the customer may choose any one of the ECC curves as shown in Fig. 2.
Step 2: The SMS gateway receives the encrypted SMS, which is delivered to the server
Step 3: The server receives the encrypted SMS and executes the decryption application. Next, the user runs decryption activity and selects the P-224 private key. After decryption, the message is shown in Fig. 3.
Step 4: After the message is decrypted, the user presses the “Next” button to communicate with the payment gateway.
Step 5: Now, the merchant fills in the remaining fields of merchant UPI-id, mobile number, and purpose of payment and then selects any payment gateway as shown in Fig. 4.
Fig. 4: The merchant enters the details and sends to any payment server
Dr Bojjagani’s research will further refine the parameters of security in IoT enabling wearable devices to become smarter and safer.
- To make the proposed protocols more secure can add biometric-based authentication can be added.
- The future directions of the proposed framework fit only for micro-payments. In future, we have upgraded to credit card/debit card payments to enhance the proposed framework for macro-payments.
