The size of ZnO nanorods (NRs) plays an important role in tuning the external quantum efficiency (EQE) and quality of light generated by white light emitting diodes (LEDs).
لم يكن معروفاً حتى منتصف القرن التاسع عشر ميلادي إلى أي مدى تنطبق قوانين الفيزياء والكيمياء على المواد الحية إذ أن هذه القوانين صيغت للجوامد. وكان واضحا بالتأكيد أن هذه القوانين تُطبق على الأجسام…
In this study, the quantitative analysis of heavy elementals contents available in drinking water are studied using one step technique; laser induced breakdown spectroscopy (LIBS) technique.
