blue volatile

Atmospheric aerosol particle size distributions at a continental background site in Eastern Germany were examined for a one-year period. Particles were classified using a twin differential mobility particle sizer in a size range between 3 and 800 nm. As a novelty, every second measurement of this experiment involved the removal of volatile chemical compounds in a thermodenuder at 300C. This con...

nvm malloc: Memory Allocation for NVRAM

2015

David Schwalb Tim Berning Martin Faust Markus Dreseler Hasso Plattner

Non-volatile main memory (NVRAM) has the potential to fundamentally change the persistency of software. Applications can make their state persistent by directly placing data structures on NVRAM instead of volatile DRAM. However, the persistent nature of NVRAM requires significant changes for memory allocators that are now faced with the additional tasks of data recovery and failure-atomicity. I...

Volatile compounds of headspace gas in the Japanese fish sauce ishiru.

Journal: :Bioscience, biotechnology, and biochemistry 2002

Toshihide Michihata Toshihiro Yano Toshiki Enomoto

Volatile compounds from the headspace gas of ten brands of the Japanese fish sauce ishiru were analyzed by GC-MS with a thermal-desorption cold-trap system. Many volatile peaks were detected and 51 compounds were identified. The major volatile compounds in ishiru included aldehydes (such as 2-methylpropanal, 2-methylbutanal, 3-methylbutanal, and benzaldehyde), nitrogen-containing compounds (suc...

مطالعه مقایسه ای حذف eriochrom blue, brilliant blue , safranin-o از نمونه های آبی با استفاده از نانوذرات مغناطیسی اکسیدآهن

پایان نامه :وزارت علوم، تحقیقات و فناوری - دانشگاه پیام نور - دانشگاه پیام نور استان فارس - دانشکده علوم پایه 1392

زینب اورنگ, صدیقه کامران هکانی,

نانوذرات مغناطیسی اکسیدآهن برای جذب سطحی رنگ اریوکروم بلو، بریلیانت بلو و سافرانین-o از محلول آبی مورد استفاده قرار گرفت. اندازه میانگین و ریخت شناسی نانوذرات با استفاده از تکنیک های temو xrd مشخص شد. مطالعات جذب سطحی رنگ اریوکروم بلو، بریلیانت بلو و سافرانین- oتحت شرایط آزمایشی مختلف صورت گرفت. از قبیل میزان نانو ذره، غلظت رنگ،ph محلول، قدرت یونی و زمان تماس (زمان بهم خوردن). نتایج آزمایش نشان...
