The performance and composition of cutsheet papers used in office printing applications are changing. Expanding markets in China and Asia, increasing worldwide demand, economic factors, and limitations on the availability of high-quality pulp have resulted in production of papers with more large-particle, abrasive filler content. Some of these papers manufactured in Asia and sold primarily in C...

The development of computational devices can provide computer-generated holograms (CGH) over 100 Giga-pixel easily. performance improvement the graphical processing unit makes calculations faster with a normal personal computer. In contrast, output device CGH is not reported much. Since fringe pattern, high resolution and fine pixel pitch are required for device. We have been developing direct ...

We report on manufacturing of a compact beam homogenizer module including two lens arrays and an aperture. Lens are fabricated by all laser-based technology employing precise femtosecond pulsed laser ablation CO2 polishing step. Each array is processed revealing high contour accuracy roughness 25 nm. The 8x8 designed to have square footprint generate quadratic Top-Hat profile focal length 10 mm...

In this work, a new and facile dry printing method was developed for the direct fabrication of superhydrophobic patterns based on silica nanoparticles. Mixtures of hydrophobic fumed silica nanoparticles and toner powder were printed on paper and polymer sheets using a commercial laser printer to produce the superhydrophobic patterns. The mixing ratio of the toner powder (for the laser printer) ...

Innovation in product development, technological breakthrough, and market entry plays a key role in firms’ competition, and the merits of innovation are quite obvious such as taking a first-mover advantage or earning lion’s share. However, innovation pays more and push firms dedicate more resources and commitments to it. Though it is a good strategy for firms to grow and profit, it isn’t an opt...

This paper presents the design of a multi-spacecraft system for the deflection of asteroids. Each spacecraft is equipped with a fibre laser and a solar concentrator. The laser induces the sublimation of a portion of the surface of the asteroid, and the resultant jet of gas and debris thrusts the asteroid off its natural course. The main idea is to have a formation of spacecraft flying in the pr...
