Development of a natural light reproduction system for maintaining the circadian rhythm
Indoor and Built Environment, 2020Circadian rhythm is linked to sleep, arousal and human health overall, affecting body temperature and heart rate. A 24-h natural-light cycle provides optimum lighting environment for humans.

The hybrid lighting system with natural light and LED for tunnel lighting
, 2020The traditional tunnel lighting has the problem of poor lighting environment and huge energy consumption. This study uses natural light and LED as the light source to design two different lenses.

Enhanced Chemiluminescence Induced by Natural Light-Driven MIL-100(Fe)/TiO2 for Dopamine Detection.
Analytical ChemistryLuminol-based chemiluminescence (CL) systems, as a powerful tool for bioanalysis, are limited owing to their weak CL intensity and self-decomposition of the classic oxidant H2O2.

ON Maxwell's theory, lines of electric force which are not anchored to charged particles travel at right angles to themselves with the velocity of light. A circular line of force travelling at right angles to its plane would fulfil this condition and would travel unchanged without loss of energy; it would thus possess one of the properties of the ...

Abstract This chapter reconstructs a hexaemeral theory of light from a combined reading of the sources. Through the causal interlink of fire and light, hexaemeral light is theorized as the purest kind of fire. The chapter explores the language and physical properties of fire that explain luminosity: the light ray, its liminal ...

A heterostructure membrane with natural-light photocatalytic activity
, 2020For the first time, a heterostructure was synthesized by bismuth oxychloride and Zn-Cr layered double hydroxide. A novel membrane photocatalyst was then obtained by dispersing the heterostructure in polyvinylidene fluoride.

AbstractSimulating natural light is an interesting subject in computer graphics. Using the principles of meteorology, we build a sphere cap light source model. Unlike existing illumination or light source models, we consider the effects of both the ratio of direct light to diffuse light and the position of the sun under different weather conditions. We
