Hydroxyapatite (HAP)-loaded gelatin, a biopolymeric composite, has gained a lot of attention in biomedical applications like bone regeneration because it compensates for the low fracture stiffness and fragility of pure HAP. Furthermore, it improves bone injury tolerance by controlling the amorphous calcium phosphate deposition kinetics and microstructure. Doping metal ions in HAP and thereafter preparing gelatin/HAP composites may result in an increase in the desired property upgrades. Understanding the breakdown kinetics of gelatin/HAP composites offers the opportunity for the composites to be engineered for specific purposes. In the present work, gelatin/HAP composites with/without metal-ion doping were prepared and subjected to thermal degradation studies using thermogravimetric analysis under a nitrogen environment to understand their degradation kinetics.

Carbon Quantum Dots (CQDs) is a progressive type of zero-dimensional material, inherits the benefits of tiny molecules (e.g., fluorophores) and classic semiconductors (e.g., inorganic quantum dots), as well as new features. A novel attempt has been made in synthesizing photo luminescent CQDs using corn cob extract by adopting a hydrothermal approach. The synthesized CQDs were characterized to understand their chemical, structural, and morphological portrayals. The application of CQD as a deposition regulating additive in lithium metal anode batteries has been explored. Lithium/lithium (Li-Li) symmetric cells fabricated using CQD additive loaded with LiPF6 electrolyte displayed small overpotential and relatively good cycling stability when compared to the Li-Li cell without additive. Full cells (Li-NMC) fabricated using Li-NMC cathode, lithium metal anode, and CQD additive loaded electrolyte showed about 10% increment in specific discharge capacity in comparison to the coin cells fabricated using LiPF6 electrolyte, signifying the positive contribution in controlling the dendrite growth.
