Iodine-Free Electrolyte for DyeSensitized Solar Cells
Dye-Sentitized Solar Cells (DSSCs) are an emerging low-cost third generation photovoltaic technology particularly suited for efficient light to-electricity conversion in indoors low-light environments. Electrolyte leakage due to the corrosive nature of iodine/iodide-containing electrolytes is currently the key issue preventing the technology’s productisation and wider deployment.
Rapid Prototype Manufacture of Polymeric Microfluidics inserts and Devices
The novel technology developed by the Microfluidic Group in UCD, funded by Enterprise Ireland allows the rapid manufacture of low-cost microfluidic inserts suitable for either small multiple prototype runs or for scale up polymer manufacture of 10,000+ parts using medical polymers, taking less than 1 hour for the manufacture and preparation of industrially viable inserts with features as low as 100 micron. A key issue for production of plastic microfluidics is fabrication of inverted microstructured tools. Mass production tools must be strong, durable, with the required feature size and aspect ratio, maintain a good demolding capability with a feasible draft angle, appropriate surface finish and a good cost/performance ratio. Normally technologies are slow (days) and/or expensive requiring the manufacture .
nanotechnology - manufacturing for nanoscale architectures
A method for the manufacture of patterned microparticles comprises immobilizing microparticles, including nanoparticles, to be patterned on a surface of a porous membrane, causing an inorganic or organic coating material which can bind to exposed surfaces of said microparticles, and which can permeate through the pores of said membrane, to flow relative to said immobilized microparticles, and removing the microparticles from the membrane following binding of said coating material. The method enables one to prepare a wide range of anisotropically-modified patterned microparticles, including microparticles patterned with nanoparticles or a biomolecular material such as DNA and protein. The patterned microparticles produced can be used in wide range of applications in health, information and communication, and sustainable environment such as shelter, clothing, energy, food, transport and security.
