In the present research influences of different combinations of five types of inoculants and four types of nodularizers on eutectic nucleation in ductile cast iron were studied. The alloys were kept at 1320°C for 0, 5, 10, 15 and 20 min under nitrogen atmosphere. Cooling curves and image analysis were used to characterize the influence of holding time and different combinations of inoculants an...
A dense and thick flake-like cathode structure was demonstrated to have a preferential crystallographic orientation for Li(+) migration and a better tolerance to cracking, both of which enable a reversible and stable capacity at moderate rates from 0.1 to 2 C.
The aim of this study was to understand the processability thirty pure cultivar oat batches and how physical properties groats flakes affect characteristics flake flour. This conducted by investigating relationship between chemical composition oats groats, flours produced industrial scale milling process. It clearly shown that behaved differently in process were interrelated. For example, separ...
A highly effective adsorbent comprised of the Graphene membrane was created using sonification method in this study. For all we know, resulting employed as an for transformer oil purification first time. The quality treated evaluated through several factors, such acid number TAN(mg KOH/g), color, breakdown voltage, and viscosity. results indicated that exceeded other commercial adsorbents terms...
مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
If possible, all surfaces painted with lead-based paint should be abated by replacement, encapsulation, or paint removal. Ordinary paint is never an appropriate encapsulant; it is only part of a temporary maintenance procedure. Encapsulation materials should be durable and, where possible, affixed with both fasteners and adhesive. Paintlike coatings should be used with caution. Only coatings an...
I t is due cause for wonder 1hat mole cules of water "know" how to frame the elaborate syrr.metries of a snow flake. There is no architect directing the assembly, and (he molecules themselves carry within them no template for the crystalline form.
