• Polymer Mediated Crystal Habit Modification
  Prevention of crystal growth and modification of crystal morphology in aqueous systems has received considerable attention recently due to changes in the water treatment industry instigated by economic and environmental pressures. Water costs, especially in the western United States, are forcing...
• Quartz Crystal Basics: From Raw Materials to Oscillators (.pdf)
  Loss (High Q): Quartz crystals. but it once again declined after the war ended. exhibit excellent aging hysteresis. In other. Working with natural quartz for electron-. words, the products' stable performance is. 54. High Frequency Electronics. High Frequency Design. CRYSTAL TUTORIAL. adjusted...
• Programmable Crystal Oscillators with Sub-ps Jitter and Multiple Frequency Capability
  frequencies,. quartz crystals transformed the LC-tuned radios of the day into vital communication. tools. With the war effort underway, the frequency control industry was experiencing. astounding growth. Indeed, the crystal industry lived hand-to-mouth due to material. shortages of quartz. Long...
• Mitigation of Tin Whiskers in VersaLogic Embedded Computing Products
  years. Tin whisker problems were resolved with the addition of lead to tin in solder in the late 1950's. The ecologically-driven effort to remove lead from electronic products has resulted in renewed interest in tin whisker growth. These tin whiskers can grow to a length that can cause electrical...
• Grasping Lyophilization Product and Process Parameters for Biopharma
  is governed by ice nucleation and crystal growth rates in supersaturated solutions. It is accompanied by freeze concentration of the solution, a process that may result in both crystalline or amorphous solids, or in mixtures. Materials Science. Correct identification of the physical and chemical...
• PAT and the Crystallization Toolkit
  and MSZW information allows suitable zones of operation to be identified. To encourage growth and minimize nucleation, crystallization should occur within the metastable zone. Seeding the process can help. Seeding can be a useful method for increasing crystal size and ensuring a robust process...
• MICRO: Facility Report
  are then melted in the quartz crucibles of the rows of crystal pullers in the factory. Then crystal growth and the pulling of the ingots takes place, followed by the sawing of the silicon rods, edge rounding of the newly sliced wafers, grinding and lapping, polishing, and cleaning. The process concludes...
• MICRO: Reality Check
  . The cost of thin-film-transistor liquid-crystal display (TFT-LCD) panels has been steadily dropping, and significant price reductions of LCDs have led to their explosive growth. For example, for LCD monitor sizes of 20 in. and smaller, the price per diagonal inch has dropped from about $100 before 2001...
• PAT and the Crystallization Toolkit
  crystals crystal growth. By manipulating the relative magnitude of these mechanisms, it is possible to design a robust crystallization with a desirable final product particle size. For example, if small crystals are desired to increase bioavailability, or to avoid a milling step, nucleation should...
• Controlling Crystallization through Modeling
  This quick, one-time registration gives you access to members-only site benefits. Controlling a product s crystal size distribution (CSD) is one of the key challenges in drug manufacturing. CSD control is critical to successful crystallizer operation and to product quality and purity, as CSD often...
