Riba equal quantities of the same kind of commodity ("like for like") — for example 100 kilograms of wheat for 100 kg of wheat — in a riba-free transaction called for by quoted ahadith. Or how "divine law" could prescribe that a jeweler — "who has spent his time and effort to convert gold into jewelry" and is taking gold as payment — not be compensated? M.A. Khan also notes that the authors of the IIIE blueprint have no objection to traders selling higher purity/quality commodity for cash and using the proceeds to buying more less purity/quality commodity, and wonders what
Ultra-high-purity steam for oxidation and annealing processes are commonly used to generate TCO layers and modify crystal structures via grain size or defect repair. The ability to deliver water vapor free from atmospheric contaminants is critical to film integrity. The ideal water vapor for industrial manufacturing processes is extremely pure, moderate in temperature and free of extra oxygen or water microdroplets. In addition, this water vapor is ideally delivered in a range of flow rates from sccm to slm, into vacuum or atmosphere pressure environments for days or weeks at a time. Purity is paramount in avoiding contamination. Purity can be achieved by blending pure gases
