The X-ray diffraction revealed that there was formation of a pure crystalline phase, consisting only of anatase for all conditions of synthesis. Both temperature and reaction time proved to have a ...

Abstract: An anodic alumina oxide (AAO) film with nano-roughening is added on the top window layer of AlGaInP light-emitting diodes (LEDs) to improve the light extraction of the device. The AAO film ...

so it is necessary to add aluminum (sodium aluminate) to the synthesis mixture. Figure 1 shows XRD patterns of the coal ash from Siderópolis. The mineral analysis shows the presence of crystalline ...

Abstract: Aluminum-doped zinc oxide (AZO) thin films have been used in low cost transparent conductive oxide (TCO) applications. For flexible electronics, the devices are subjected to cyclic bending ...

Table 2. FTIR bands of the matrixes (PVA and PVA-CMC) and of the herbal extracts (dragon’s blood and sage). Amorphous and crystalline gels result in different rates of degradation (weight loss - WL) ...

Obesity has traditionally been thought of as a state of caloric imbalance, where the intake of calories exceeds the expenditure or ‘burning’ of calories. However, a more nuanced appreciation for the ...

But aluminum does oxidize, a process that’s similar to rust except that instead of iron combining with oxygen to make iron oxide (the chemical name for rust), aluminum combines with oxygen to ...
