Eu3+ doped YVO4 nano phosphors were synthesized by adopting a simple Co-Precipitation Method (CPM). In order to compare and evaluate this method's potentiality, we prepared the same phosphor by using a conventional Solid State Reaction method (SSR). X-Ray Diffraction (XRD) profile confirms the tetragonal nature of Eu3+ doped YVO4 nano phosphors. The efficiency of the prepared phosphors was analyzed by means of its emission spectral profiles. We also observed a rich red emission from the prepared phosphors under a Ultra-Violet (UV) source. Such luminescent powders are expected to be applied as red phosphors in display device applications. In addition, Scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Fourier-Transform IR spectroscopy (FTIR), and Raman Spectrum were also used to characterize the synthesized phosphor.

Proton-Conducting Polymer Wrapped Cathode Catalyst for Enhancing Triple-Phase Boundaries in Proton Exchange Membrane Fuel Cells

Meenakshi Seshadhri Garapati, Divya Nechiyil, Sebastien Joulie, Revathi R. Bacsa, Ramaprabhu Sundara, Wolfgang Bacsa

Summary: The study focuses on improving the performance and durability of proton exchange membrane fuel cells (PEMFCs) by synthesizing different weight percentages of proton-conducting poly(vinylphosphonic acid) (PVPA) wrapped nitrogen and sulfur doped carbon nanotubes as catalyst support. The results show that the PVPA coating enhances the triple-phase boundary density and durability of the cathode catalyst, leading to increased activity and stable electrochemical performance. The systematic variation of PVPA weight percentage helps to find the optimal proton-conducting polymer content for achieving high performance PEMFCs.

Effect of Coordinated Solvent Molecules in Cu-MOF on Enzyme Free Sensing of Glucose and Lactate in Physiological pH

Anamika Ghosh, T. K. Sana Fathima, Sundara Ramaprabhu

Summary: Developing a nonenzymatic sweat sensor for selective determination of glucose and lactate holds great significance in clinical diagnostics. Metal-organic frameworks (MOFs) based on transition metals have gained attention for their tunable porosity and enhanced electrocatalytic activity. This study investigates the influence of solvent molecules on the structural and electrocatalytic properties of Copper-terephthalate (CuBDC) MOF and demonstrates its superior sensitivity in detecting glucose and lactate in a neutral medium. The proposed sensor shows good sensing performance in artificial sweat, making it suitable for practical and non-invasive sweat sensing applications.

Design and Performance Enhancement of Cobalt-Encapsulated Nitrogen-Doped Carbon Nanofiber Electrocatalyst through Ionic Liquid Modification for Efficient Oxygen Reduction

Sanjit Kumar Parida, Dipsikha Ganguly, Tulasi Barik, Rajendra Kumar Sharma, Sankarakumar Amirthapandian, Hrudananda Jena, Ramaprabhu Sundara

Summary: Designing platinum-group-metal-free (PGM-free) electrocatalysts with high activity and durability for the oxygen reduction reaction (ORR) in acidic environments is challenging. In this study, a Co-encapsulated nitrogen-doped carbon with nanofiber networks and its ionic liquid-modified interface showed efficient ORR activity in an acidic medium. The catalyst showed promising activity and durability comparable to Pt/C, with a half-wave potential of 0.71 V vs RHE and only 11 mV reduction in activity after 5000 cycles. It also retained 71% of its original current in a short-term durability test and exhibited superior performance among reported nonPGM catalysts.

Sandya Rani Mangishetti, M. Kamaraj, Ramaprabhu Sundara

Summary: A strategy for preparing electrode materials with high conductivity, high surface area, and hierarchical pore structure, along with nitrogen functional groups, to enhance the electrochemical performance of electrochemical capacitors is presented.

The addition of nitrogen-doped porous carbon further improves the electrochemical performance, with enhanced pseudocapacitance and overall supercapacitive performance. The developed electrode material shows high specific capacitance and energy density, making it a promising candidate for supercapacitor applications.

Rare-Earth Doped Configurational Entropy Stabilized High Entropy Spinel Oxide as an Efficient Anchoring/Catalyst Functional Interlayer for High-Performance Lithium-Sulfur Battery

Arindam Chatterjee, Dipsikha Ganguly, Ramaprabhu Sundara, Subramshu S. Bhattacharya

Summary: Lithium-sulfur batteries (LSBs) are promising energy storage devices due to low-cost sulfur-based cathode and high energy density. However, the shuttle effect of lithium polysulfide (LiPS) and slow redox kinetics of lithium sulfide (Li2S) formation hinder their commercial viability. In this study, a transition metal-rare earth high entropy oxide (TM-RE HEO) was designed as a polysulfide adsorbent and catalyst for redox reactions in Li-S batteries. The TM-RE HEO demonstrated enhanced discharge capacity, high rate capability, and long-term cycling stability. This work highlights the potential of high entropy oxide in developing efficient LSB technology.
