“…The modern industrial societies are increasingly extravagant in the use of nano/micro materials for various advance applications. Advanced materials generally have superior properties to conventional materials available, thus they could simply outperform conventional materials in terms of their properties and applications [ 1 , 2 ]. Advanced materials have been extensively used in various high-tech industries, like medical, aerospace, automotive, power sector etc.…”

Bamboo fibers are utilized for the production of various structures, building materials, etc. and is of great significance all over the world especially in southeast Asia. In this study, the extraction of microcrystalline cellulose (MCC) was performed using bamboo fibers through acid hydrolysis and subsequently different characterizations were carried out using various advanced techniques. Fourier transform infrared (FTIR) spectroscopy analysis has indicated the removal of lignin from MCC extracted from bamboo pulp. Scanning Electron Microscopy (SEM) revealed rough surface and minor agglomeration of the MCC. Pure MCC, albeit with small quantities of impurities and residues, was obtained, as revealed by Energy Dispersive X-ray (EDX) analysis. X-ray diffraction (XRD) indicates the increase in crystallinity from 62.5% to 82.6%. Furthermore, the isolated MCC has slightly higher crystallinity compared to commercial available MCC (74%). The results of thermal gravimetric analysis (TGA) demonstrate better thermal stability of isolated MCC compared to its starting material (Bamboo fibers). Thus, the isolated MCC might be used as a reinforcing element for the production of green composites and it can also be utilized as a starting material for the production of crystalline nanocellulose in future.

“…[32][33][34] The macroscopic moduli are essential in crystal structures since they determine properties such as hardness, resistance to volume change under field stress, stiffness and resistance to distortion under shear stress. 35,36 We note that the calculated moduli increase with the decrease of cell volumes, suggesting that NiCO 3 possesses greater hardness and resistance to volume change under pressure (higher bulk modulus), stiffness (higher Young's modulus) and resistance to distortion under shear stress (higher shear modulus) over CoCO 3 and MnCO 3 , respectively.…”

We report first-principles calculations on the structural, thermodynamic, electronic, elastic and dynamic properties of transition metal carbonates, MCO3 (M= Mn, Co, Ni) at 0 K. These materials are projected to be excellent candidates as precursors for advanced cathode materials in rechargeable lithium-ion batteries which employ an NMC chemistry. We have employed the plane-wave pseudopotential method framed within the density functional theory (DFT) as embedded in the VASP code. The exchange-correlation functional of Perdew, Burke and Ernzerhof (PBE) was used. Moreover, the Hubbard U-correction in the rotationally invariant form was applied to improve the description of the strongly correlated 3d electrons of the transition metals. The structural cell parameters were calculated to 96 % agreement with the experimental data, warranting the robustness of the approach employed. All MCO3 crystal systems have negative enthalpies of formation, indicating thermodynamic stability leading to good cycling performance and safety. All the elastic constants for the considered transition metal carbonates satisfied the necessary stability conditions, indicating mechanical stability. Moreover, negative vibrations are not observed in the high symmetry directions of the Brillouin zone, suggesting dynamical stability.
