Man-made structural colors, which originate from resonant interactions between visible light and manufactured nanostructures, are emerging as a solution for ink-free color printing. We show that non-iridescent structural colors can be conveniently produced by nanostructures made from high-index dielectric materials. Compared to plasmonic analogs, color surfaces with high-index dielectrics, such...
3D printing known as additive manufacturing (AM) has been applied for applications in different fields such as aerospace, automotive, biomedical, and energy industries. It is the fact that 3D printing has gained a very wide acceptance over the last decade. However, several significant hurdles prevent its wider adoption. One of the most important barriers is the quality of the printed parts. Cur...
Formation and Characterization of Inkjet-Printed Nanosilver Lines on Plasma-Treated Glass Substrates
In this study, we investigated geometrical characteristics of the inkjet-printed lines with non-zero receding contact angle (CA) on plasma-treated substrates in terms of various printing variables and analyzed the fluidic behavior and hydrodynamic instability involved in the line formation process. The printing variables included surface energy, droplet overlap ratio, printing frequency, a numb...
We report on inkjet printing of aqueous colloidal suspensions containing monodisperse silica and/or polystyrene nanosphere particles and a systematic study of the morphology of the deposits as a function of different parameters during inkjet printing and solvent evaporation. The colloidal suspensions act as a model ink for an understanding of layer formation processes and resulting morphologies...
3D printing and numerical analysis are combined to design a new class of architected materials that contain bistable beam elements and exhibit controlled trapping of elastic energy. The proposed energy-absorbing structures are reusable. Moreover, the mechanism of energy absorption stems solely from the structural geometry of the printed beam elements, and is therefore both material- and loading...
the aims of this study were to determine hippuric acid and toluene in urine samples, airborne toluene levels, health effects, and to describe any correlation between specimen samples. seventy-five printing workers exposed to toluene at work (exposed group), and 60 nonexposed people (control group) were studied. study participants were selected from same factories in the different positions. uri...
Abstract The energy transition is one of the main challenges our society and therefore a major driver for scientific community. To ensure smart to sustainable future scenario different technologies such as harvesting using solar cells or windmills chemical storage in batteries, super-capacitors hydrogen have be developed ultimately deployed. New fabrication approaches based on additive manufact...
Here, we report multilayer stacking of films of quantum dots (QDs) for the purpose of tailoring the energy band alignment between charge transport layers and light emitting layers of different color in quantum dot light-emitting diodes (QD LED) for maximum efficiency in full color operation. The performance of QD LEDs formed by transfer printing compares favorably to that of conventional device...
