No single answer to the question “What is light?” satisfies the manycontextsin which light is experienced, explored, and exploited. The physicist is interested in the physical properties of light, the artist in anaestheticappreciation of the visual world. Through the sense of sight, light is ...

The energy absorption performance of thin-walled structure is closely related not only to the material properties of the structure, but also to the geometric parameters such as the section shape and wall thickness of the structure. Alexander [4] put forward the theoretical model of axisymmetric ...

Binding several candles together will result in flickering of candle flames, which is generally described as a nonlinear oscillator. The impact on the frequency of the flame by several factors, such as the arrangement, the number and the asymmetry of the oscillators, is discussed. Experimental ...
Fenton-like system formed in a natural soil environment deemed to be significant in the aging process of biochar. Aged biochars have distinct physico-chemical and surface properties compared to non-aged biochar. The aged biochar proved to be useful soil amendment due to its improved elements conten...

We reported the temperature-dependent device characteristics of InGaN/GaN green flip-chip light-emitting diodes (large chip size of 1125×1125μm2) on patterned sapphire substrate. Through the experiments in the temperature range of 298–358K, optical, electrical, and spectral properties were measure...
