Trace Analysis Methods for Actinides in Aqueous Systems.

Multiconfigurational quantum chemical methods for molecular systems containing actinides.

Recent advances in computational actinide chemistry are reported in this tutorial review. Muticonfigurational quantum chemical methods have been employed to study the gas phase spectroscopy of small actinide molecules. Examples of actinide compounds studied in solution are also presented. Finally the multiple bond in the diuranium molecule and other diactinide compounds is described.

Enrichment Methods in Trace Analysis

Enrichment methods are classified according to the type of sample for which they are to be used, and basic analytical principles are applied to develop criteria for choice of enrichment method and conditions to be used. The topic of 'enrichment' or 'preconcentration' of trace elements has assumed great importance not only in the field of high-purity materials but also in connection with polluti...

islanding detection methods for microgrids

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...

Trace Analysis of Phosphates in Small Aqueous Volumes

-The indirect determination of trace amounts of phosphate through estimation of the molybdenum in the phosphomolybdic acid complex has been improved. The lower limit of spectrophotomctric determination is about 0.I0 pg P.
