to evaluate the effect of different light intensities on the degree of conversion (dc) of dual-cured resin cement at different depths of translucent fiber posts.thirty translucent fiber posts were randomly assigned into three (n=10) groups. they were cemented in the simulated canal spaces using duo-link dual-cured resin cement. the cement was light-cured under 600, 800 and 1100 mw/cm(2) light i...

Recyclability is an important aspect for heterogeneous photo-catalysts. Ease of recovery and stability of the photo-catalyst in terms of efficiency over the number of cycles are highly desired and in fact it is ideal if the efficiency is constant and it should not decrease marginally with each cycle. Presented here is a seminal observation in which the photocatalytic activity is shown to improv...

The fabrication of functional metamaterials with extreme feature resolution finds a host of applications such as the broad area of surface/light interaction. Nonplanar features of such structures can significantly enhance their performance and tunability, but their facile generation remains a challenge. Here, we show that carefully designed out-of-plane nanopillars made of metal-dielectric comp...

introduction: the human skin is an active medium from the optical point of view. therefore, the diagnostic and therapeutic techniques employing light are increasing. current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. studies have shown that biological tissues, and in particular skin, demonstrate polarization...

AM-6 with high intensity visible light absorption at 400-800 nm was synthesized via a hydrothermal route in the presence of F(-) ions. Structure characterization and DFT calculations indicate that the unusual optical properties originate from the connection of octahedral VO(6) wires with distorted tetrahedral VO(4) units, which are stabilized in the framework of AM-6.

We theoretically and experimentally demonstrate that carbon self-doping could induce intrinsic electronic and band structure change of g-C(3)N(4)via the formation of delocalized big π bonds to increase visible light absorption and electrical conductivity as well as surface area and thus enhance both photooxidation and photoreduction activities.

Polyclonal antibodies against kappa light chain are used to diagnose diseases producing free light chain. The kappa and lambda light chains are products of immunoglobulin synthesis and released into the circulation in minor amounts such as serum, cerebrospinal fluid, urine and synovial fluid in normal condition. The purpose of this study was the production and purification of polyclonal immunog...

To reveal the neural dynamics underlying biological motion processing, we introduced a novel golf-swing point-light motion (PLM) stimulus with an adaptation paradigm and measured event-related potentials (ERPs). In the adaptation phase, PLM and scrambled PLM (sPLM) stimuli were presented; a static point-lights stimulus was also presented as a control condition. In the subsequent test phase, PLM...

The 2003 International Prize for Biology was awarded to Shinya Inoue for his pioneering work in visualizing dynamic processes within living cells using the light microscope. He and his scientific descendants are now pushing light microscopy even further by developing new techniques such as imaging single molecules, visualizing processes in living animals, and correlating results from light and ...
