Space Survivable Polyimides with Excellent Optical Transparency and Self-Healing Properties Derived from Hyperbranched Polysiloxane
A novel space survivable polyimide with a variety of desirable properties such as excellent thermal stability, high optical transparency, good mechanical strength, satisfactory break elongation, and outstanding atomic oxygen (AO) erosion resistance has been prepared by first synthesizing hyperbranched polysiloxane (HBPSi) and second incorporating HBPSi into polyimide (PI) chains via copolyconden...

Probing polymer surfaces and interfaces using sum frequency generation vibrational spectroscopy- a powerful nonlinear optical technique
Sum frequency generation (SFG) vibrational spectroscopy has been proved to be a powerful technique which substantially impacts on many research areas in surface and interfacial sciences. This paper reviews the recent progress of applying this nonlinear optical technique in the studies of polymer surfaces and interfaces. The theoretical background of SFG is introduced first. Current...

Design of optical element combining Fresnel lens with microlens array for uniform light-emitting diode lighting
One kind of optical elements combining Fresnel lens with microlens array are designed simply for light-emitting-diode (LED) lighting based on Geometrical Optics and Non-imaging Optics. This design method imposes no restriction on the source intensity pattern. The designed element has compact construction and can produce multiple shapes of illumination distribution. Taking square lighting as an exa...

Lithium Salt Electride with an Excess Electron PairsA Class of Nonlinear Optical Molecules for Extraordinary First Hyperpolarizability
A new lithium salt electride with an excess electron pair is designed, for the first time, by means of doping
two sodium atoms into the lithium salt of pyridazine. For this series of electride molecules, the structures
with all real frequencies and the static first hyperpolarizability (0) are obtained at the second-order
Møller-Plesset theory (MP2). Pyridazine H4C4N2 becomes the lithium...
