Nanomaterials are characterized by their very small structures, typically ranging from 1 to 100 nanometers.
These materials are known for their distinctive optical, electrical, and mechanical properties that differ significantly from bulk materials.
One common method for creating nanomaterials is the sol-gel process, which involves the hydrolysis and subsequent condensation of metal alkoxides \( M(OR)_x \).
The reaction can be represented as follows: \[ M(OR)_x + x H_2O \rightarrow M(OH)_x + x ROH \]
When hydrogen peroxide is added to an acidified solution of KI, iodine (I2) is liberated. In this case, hydrogen peroxide acts as?
Explain the construction of a spherical wavefront by using Huygens' principle.
The slope of the tangent to the curve \( x = \sin\theta \) and \( y = \cos 2\theta \) at \( \theta = \frac{\pi}{6} \) is ___________.
