Completely bio-based poly(limonene carbonate) is a thermoplastic polymer, which can be synthesized by copolymerization of limonene oxide (derived from limonene, which is found in orange peel) and CO2. Poly(limonene carbonate) has one double bond per repeating unit that can be exploited for further chemical modifications. These chemical modifications allow the tuning of the properties of the ali...
This paper investigates thermal modelling of the selective laser sintering process for amorphcus polycarbonate powders. The aim is to develop a simulation for process accuracy and control which are key areas of developement for the new layer manufacturing rapid prototyping technologies. A state-of-the-art adaptive mesh 2 0 finite difference code is used simultaneously to consider heating and si...
Single-wall carbon nanotubes (SWNTs) are at the center of nanotechnology research. Their nonlinear optical behavior makes them promising for applications in ultrafast photonics. SWNTs are indeed good saturable absorbers, i.e., they are transparent to high-intensity light, with ultrafast recovery time. Saturable absorbers must always keep a delicate balance between the modulation depth and nonsa...
