Stent Nanocoatings with Controlled Drug Release and Improved Biocompatibility

BACKGROUND Industrial biopharmaceutical cell culture necessitates an expensive and risky scale-up process to get production scale volumes in order to manufacture proteins and other biopharmaceutical products. Traditional stirred single-use bioreactor bags can only scale to a five-fold maximum, but scaling for production requires several thousand...

Laser Fabrication of Multi-principal Element Alloy Nanoparticles

BACKGROUND In the past decade, the development of multi-principal element alloys (MPEAs), a parent domain of high entropy alloys (HEAs), has created significant interest in the materials community, particularly as structural materials due to their superior mechanical and radiation-resistant properties. MPEAs consist of multiple principal elements...

Additive Manufacturing Using Ionized Particles

BACKGROUND Modern 3D printers can print intricate shapes at fine detail, but their low print speed enables them to only be used for prototyping or, at best, limited batch manufacturing. As an example, the fasted current metal printers can print a volume of about 60 cm³/hr. per nozzle or laser. This equivalent to about 8 grams/minute for a...

Fabrication of Large Area Gold-based Metalenses

BACKGROUND Surface plasmons (SP) and surface plasmon polaritons (SPP) are nonlinear 36 many-body excitations that couple light with the electron density of states of a material, in 37 particulars, metals. The nonlinear nature of SP and SPP can be used for frequency doubling of 38 light (second harmonic generation) and the formation of evanescent...

TFT-less IR-driven OLED Display

BACKGROUND TV screen sizes are getting bigger and bigger every year. However, manufacturers using organic light-emitting diode (OLED) technology face a big challenge in fabricating TV screens over 100 inches at reasonable cost. Unlike the OLED process which is compatible with low-cost, low-temperature, and large area processing methods including...

Textile repurposing and sustainable garment design

BACKGROUND Occupying nearly 5% of all landfill space, textile waste (e.g., clothing, footwear, accessories, carpets, towels, bedding, drapery) has continued to make a negative impact on our environment. A variety of textile recycling methods have been developed that convert discarded textile fibers into raw materials (e.g., yarn, fibers, polymer chips)....
