Chemical Reactivities of Fibers

Collisions of ultracold 23Na87Rb molecules with controlled chemical reactivities

The collision of molecules at ultracold temperatures is of great importance to understand the chemical interactions at the quantum regime. Although much theoretical work has been devoted to this, experimental data are only sparsely available, mainly because of the difficulty in producing ground-state molecules at ultracold temperatures. We report here the creation of optically trapped samples o...

investigation of thermal comfort properties of woven sport fabric using blend of estabragh fibers

امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...

Chemical Sensing Using Microbent Optical Fibers

Introduction Microbend loss has always been an undesirable effect causing problems in fiber optic communication links. However, this phenomenon has been exploited profitably in fabricating a variety of fiber optic sensors [1-46] and in other applications such as development of mode strippers and mode scramblers [47], mode filters, phase shifters [48,49], signal processing [50] etc. The sensing ...

Chemical reactivities as a mirror of environmental transformations - method development and assessment of some selected organohalogens

The assement of chemical persistence is an important part of legislative protection of the environment and human health. Of the vast number of chemicals on the market today few have been properly assessed. The coordination between testing guidelines from different frameworks is limited and especially the methods for determination of biodegradation show poor reproducibility because of their high...
