Microstereolithography ~mSL! uses laser light to solidify UV-curable resin mixed with concentrated ceramic powders. During the mSL process, the light scattering from the particle suspension is found to significantly influence the fabrication resolution in both lateral and depth dimensions which are critical for the complex three-dimensional ~3D! microfabrication. In this work, we performed Mont...

We report the fabrication of broadband antireflective silicon (Si) nanostructures fabricated using spin-coated silver (Ag) nanoparticles as an etch mask followed by inductively coupled plasma (ICP) etching process. This fabrication technique is a simple, fast, cost-effective, and high-throughput method, making it highly suitable for mass production. Prior to the fabrication of Si nanostructures...

carbon nanotube, a new structure of carbon element, is composed of graphene sheets rolled into closed concentric cylinders with diameter of the order of nanometers and length of micrometers. liquid arc discharge was used for fabrication of carbon nanotubes, and subsequently a modified acid treatment method applied for purification stage. a statistical design of experimental (doe) (taguchi metho...

Collagen I hydrogels are commonly used to mimic the extracellular matrix (ECM) for tissue engineering applications. However, the ability to design collagen I hydrogels similar to the properties of physiological tissues has been elusive. This is primarily due to the lack of quantitative correlations between multiple fabrication parameters and resulting material properties. This study aims to ena...

Although the membrane process is recognized as a green technology and is considered as a key player in the process intensification movement, it is not widely known that the fabrication of membrane itself generates significant amount of waste. With the growing membrane market, more efforts must be placed on improving the sustainability of membrane fabrication such as replacing toxic organic solv...
