As another important type of SC electrode materials, transition metal compounds and composites have been widely investigated for SCs. RuO 2 was the first reported transition metal oxide for SCs.The maximum theoretical capacitance of RuO 2 is 1450 F g-1 with a 1 V voltage window, which is much larger than that of carbon materials. The material also has merits of good thermal stability, high.

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths.This spectral perspective was first noted in atomic spectroscopy.

By depositing gold nanoparticle arrays and PZT films on ITO substrates, and studying the photocurrent as well as the femtosecond transient absorbance in different configurations, we demonstrate an.

According to Joule’s well-known first law, application of electric field across a homogeneous solid should produce heat uniformly in proportion to the square of electrical current. Here we.
