The Effectiveness of Discovery-Based Virtual Laboratory Learning to Improve Student Science Process Skills
Autor: W. Nirmala, S. Darmawati
Publikováno v: Journal of Education Technology, Vol 5, Iss 1, Pp 103-112 (2021)
The inadequate condition of the laboratory, facilities, and infrastructure is the main obstacle to the lack of practicum activities. The purpose of this study was to examine the effectiveness of discovery-based virtual laboratory learning in improvin

Synthesis, growth, crystal structure, vibrational, DFT and HOMO, LUMO analysis on protonated molecule-4-aminopyridinium nicotinate
Autor: W. Nirmala, R. Santhakumari, S. Mugeshini, Ranjith Balu, Suresh Sagadevan, N. Rajeswari, R. Vasanthakumari
Publikováno v: Journal of Molecular Structure. 1239:130449
An organic crystal 4-aminopyridinium nicotinate (4APNA) single crystal has been grown by a slow evaporation method. The crystallinity and structural orientation of as-grown 4APNA compound was thoroughly studied using single-crystal X-ray diffraction

Autor: V. Ganesh, S. AlFaify, K. Deva Arun Kumar, D. Joseph Edison, Mohd. Shkir, W. Nirmala, S. Valanarasu
Publikováno v: Physica B: Condensed Matter. 523:31-38
Aluminium doped (i.e. 3 at%) zinc oxide (AZO) thin films were prepared by simple successive ionic layer adsorption and reaction (SILAR) method with different dipping cycles. The structural and surface morphology of AZO thin films were studied by usin
