Abstract

Computational chemistry is one of the branches in chemistry that implies the finding of theoretical chemistry into efficient computer programming to monitor, calculate and examine the properties of molecules and solids, adopting these programs to real chemical problems. Intersection between virtual reality (VR) and computational chemistry would bring the strength and improve the weakness of the system for better chemistry field discovery among scholars that level up the educational development. Thus, introduction of VR as an educational medium will eventually add another new technical skill for good purpose mainly for processing data and information. This paper reviews the role of VR as a teaching device in computational chemistry courses. The innovation in teaching and learning helps students to collect more reliable and quality data on the chemical analysis that is not available from the experimental works. This will provide source and bridge for the students to easily collect and analyse data in comprehensive understanding especially deep explanation at atomic level. This teaching strategy also stimulate and attract the interest of the students to be more joyful and native in learning.

Abstract

This narrative review explores the integration of virtual reality (VR) as a transformative instructional medium in computational chemistry, focusing on how VR can address challenges such as limited 3D visualization and costly experimental setups. VR tools like iMD-VR and Nanome offer immersive interaction with 3D molecular structures, enhancing both conceptual understanding and practical skill development. By fostering engagement, critical thinking, and confidence among learners, VR makes complex chemical phenomena more accessible. However, infrastructure limitations and insufficient empirical data persist, especially in resource-constrained regions. Recent studies emphasize cloud-based solutions and collaborative VR labs to reduce costs and improve scalability. This review highlights VR’s potential to modernize chemistry education, calling for more rigorous research to validate its long-term impact on learning outcomes.

Abstract

Thermal and surface properties of LiFePO4/very-few-layer graphene (LiFePO4/VFLG) composite manufactured through the sol-gel route have been researched for lithium-ion battery cathode application. VFLG was acquired from a facile, cost-effective, and environmentally benign fluid dynamic shear exfoliation process. The composites were characterized through thermogravimetry analysis (TGA), differential scanning calorimetry (DSC), field-emission scanning electron microscopy (FESEM) interlinked with energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and Braneur-Emmett-Teller (BET) analysis. The TGA-DSC results showed that the integration of VFLG could enhance the thermal stability of the composite by inhibiting oxygen diffusion on the LiFePO4 surface. FESEM-EDX analysis, meanwhile, confirmed the homogeneously distributed VFLG in the composites. TEM results revealed that the average particle sizes of the composites decreased by about 21.2% compared to the bare LiFePO4. TEM and HRTEM results confirmed an intimate contact between VFLG intimately and LiFePO4 particles via plane-to-point contact, contributing to the control and reduction of particle size. Furthermore, physisorption via BET analysis revealed that incorporating VFLG provided a wider distribution of mesopores and increased pore diameter and pore volume by 128.7% and 656.3%, respectively, compared to sole LiFePO4. These significant improvements were related to the flexibility and ability of a thin layer of VFLG to limit the growth of LiFePO4 particles. This approach offers a promising strategy to enhance the thermal stability and surface properties of lithium-ion battery cathodes.
