RFID tag, NXP, 1994. RFID tag, Legic, early 90s. Is a collection of logic cells found in silicon chips. The collection is provided freely for the study, comparison, and reverse-engineering of silicon implementations. These libraries vary for different manufacturers and process generations. The Silicon Zoo wants to make as many as possible of these libraries available to researchers. The slides of a talk at The Last HOPE.

Silicor Materials Home Page Video. Silicor Materials is the leading manufacturer of high-quality solar silicon, currently powering more than 20 million solar PV cells for customers around the world. Our proprietary process yields solar silicon more cost-effectively than traditional methods, without compromising product performance. By optimizing solar silicon production, Silicor will significantly improve the economics of global PV manufacturing.

The induction period between initial silica exposure and development of radiographically detectable nodular silicosis is usually 10 years. Shorter induction periods are associated with heavy exposures, and acute silicosis may develop within 6 months to 2 years following massive silica exposure. When the small silica dust particles are breathed into the lungs, they can embed themselves deeply into the tiny alveolar sacs and ducts where oxygen and carbon dioxide gases .

Which usually occurs after ten or more years of exposure to crystalline silica at relatively low concentrations. Which results from exposure to high concentrations of crystalline silica and develops five to ten years after the initial exposure. Which occurs where exposure concentrations are the highest and can cause symptoms to develop within a few weeks to four or five years after the initial exposure.
