1.2.1 Hydrofluoric acid immersion The traditional method for preparing fluoride coating on magnesium and its alloys is to immerse the sample in an aqueous solution of hydrofluoric acid for a time period that can vary from a few minutes to days. It is generally assumed that the coating is forme...
As previously discussed, amines are usually used in the removal of acid gases such as CO2 and H2S. However, these compounds have a string of downsides (Table 4). For instance, the heat generated during the reaction between the amine solution and the acid gases is crucial because it can ...

Crystals of Exo10Rrp6 bound to poly(A)24 RNA were first washed by two rounds of transfer to 1 μl well solution, then dissolved in water and TBE-urea sample buffer, and analysed by 15% TBE-urea PAGE. A drop without crystals was run as a control. RNA was stained by Sybr Gold. ...
Electrochemical properties of half-cells Prior to the fabrication of full battery, the electrochemical properties of anode (i.e., PTO-electrode) and cathode (i.e., graphite felt-electrode) in the acid electrolyte containing Mn2+ were examined by the typical three-electrode tests, respectively. PT...
of a magnesium stearate-acetriptan adduct (AD1) involving stearic acid. To further evaluate if this potential interaction could cause drug instability, an additional experiment was performed in which several different mixtures of drug and excipients were prepared. Only the excipient types used in ...
solution to this problem, actual practice falls far short of this goal, and, as will be seen in Part-Il, many of the rules for predicting Lewis acid-base reactivity are still of the qualitative rule-of-thumb variety. Such ''soft’’ science tends to be both highly verbal and intuitive ...
Synthesis of phosphonic analogues of carnitine and γ-amino-β-hydroxybutyric acid Elżbieta J. Tadeusiak, in Bioorganic Chemistry, 2004 The starting material was phosphonic ester 7 obtained from epichlorohydrin 5 and dimethyl (trimethylsilyl)phosphite 6 according to Azuhata and Okamoto [24]. Ph...
6.04.4.1.1 Direct substitution by sulfinic acid anion Direct substitution in a wide variety of electrophiles with the use of sulfinic acid salts 104 and various reaction conditions has been extensively investigated for relatively long time and still is found to be an attractive synthetic method Ther...
