بعض المصانع عند تصنيع المطاحن يقوموا بحد تروسها بشكل أكثر من اللازم لكي يطول العمر الإفتراضي للترس، ولكن عند أول الاستعمالات قد يتأثر التحضير بسبب حدة الترس التي سيفقدها بشكل تدريجي وسريع في البداية فقط، فبعض شركات المطاحن تنصح في كتيب المطحنة بطحن كمية بن معينة للوصول إلى درجة ثبات حدة الترس حتى لا يتذبذب التحضير بالأخص لأصحاب المقاهي
ZnO nanoparticles synthesized using the sol gel technique with an average diameter of nm are used to fabricate a vacuum pressure sensor in the range of 1 mbar to 10 3 mbar low vacuum limit A drastic increase in the current of the drop casted ZnO on glass with 30 µm separated Au contacts defined by e beam lithography is sensor reveals a linear relationship in current
The ratios of ZnO and ZnS can be controlled by modulating the calcination time of ZnS C composite in air for 15 30 45 and 60 min and the finally obtained ZnO/ZnS heterostructures were denoted as ZnOS 15 ZnOS 30 ZnOS 45 and ZnOS 60 respectively As shown in Table S1 Supporting Information the content of ZnS in ZnOS n decreases with
