essential to carry the light energy to travel. This is why the light energy can travel through space where there is no air, whereas it is not the same with sound waves, as they have to travel through solids, liquids or gas. Light energy is very swift and travels faster than anything el...
We demonstrated a novel InGaP integrated photonics platform for ultra-efficient, broadband second-order nonlinear optics, including time-energy entangled photon generation, transcending the current state of the art.

This definition emphasizes gender as a social construct, which changes over time, space and context. Hence, the gender dimensions of energy access and use vary across social, cultural, economic and political contexts. The objective of gender and energy policy research is an engendering energy ...
The science behind them is complex, but their benefits are simple: LEDs are smaller, brighter, and more flexible than incandescent bulbs, not to mention longer lasting and more energy-efficient. Plus, advances in microcomputing mean it’s now possible to attach tiny computerized controllers to LE...
John A.Dearien, inEncyclopedia of Energy, 2004 1Definition of Ultralight Rail Ultralight rail (ULR) is at the low end of the spectrum of weights of rail vehicles and is generally considered any vehicle with a loaded weight of less than 10,000 lbs and with a more personal type of operatio...
the locus of twist region would become the strongest actuation responsive point, and then, applying stimuli on the locus of the twist region might spread the torsional energy along with the twisted band, and further induce a continuous deformation, i.e., rotation of twist along with the ribbon...
The technological revolution of long-awaited energy-saving and vision-friendly displays represented by bistable display technology is coming. Here we discuss methods, challenges, and opportunities for implementing bistable displays in terms of molecular
