    Notes: [Auszug] 32P-labelled Grb2-fusion protein8 was used to screen an expression cDNA library constructed from a glial tumour. We focused on one novel 1.6-kilobase (kb) clone. Rescreening of libraries resulted in the isolation of a 4.2-kb transcript which contained a polyadenylation signal and poly(A) tract. ...

    Notes: [Auszug] The Dscam gene gives rise to thousands of diverse cell surface receptors thought to provide homophilic and heterophilic recognition specificity for neuronal wiring and immune responses. Mutually exclusive splicing allows for the generation of sequence variability in three immunoglobulin ...

    Notes: Abstract. The recrystallization kinetics of BF |lefbop| + |clobop||opnbop| 2 |clobop| ion-implanted silicon has been studied by means of spectroscopic ellipsometry. It has been found that the dielectric constant of the implanted layers depends on the energy dose and ion-beam current. The activation energy of the regrowth process increases with ion peak concentration becoming saturated for the largest implanted doses. In the largest-dose samples implanted at low current a significant decrease of the regrowth rate was detected when the recrystallization front crosses the peak of the impurity distribution.

    Notes: Abstract The adsorption of ethene and propene on titania and titania-supported rhodium has been studied, observing a continuous adsorption even after 24 h. The samples have been reduced at 623 or 773 K, but no difference was observed, whichever the reduction temperature or the presence of rhodium, on the amount of gas adsorbed per unit of surface area of the solid. A study of the polymerization has been done following the “equal reactivity hypothesis”, and it has been concluded that the role played by the rhodium particles is to facilitate adsorption of the gaseous molecule, that is then transfered to the surface of the support, where it polymerizes.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract During calcination of OCM catalyst precursors, Li...Cs spectacularly lower the amorphous silica → α-cristobalite phase transition temperature, shown here to be a critically important requirement for production of effective catalysts. Incorporation of W switches on OCM activity and newly discovered K/W and Rb/W formulations exhibit unsurpassed ethylene selectivity at high methane conversion. Addition of Mn significantly improves the performance of the former. An alkali-stabilised tungsten oxo species is thought to be the OCM active site.

    Description / Table of Contents: Abstract Твердые Li/MgO получены из MgO с помощью термического разложения Mg5(OH)2(CO3)4·4H2O или высаждением водных растворов нитрата магния с дальнейшим импрегнированием полученного осадка водными растворами карбоната или нитрата лития. Во всех случаях были получены непористые вещества. Удельная поверхностная площадь зависит от природы прекурсоров, а процесс MgO→Mg(OH)2→MgO является топотактическим.
    Notes: Abstract Li/MgO solids have been prepared from MgO, by thermal decomposition of Mg5(OH)2(CO3)4·4H2O or by precipitation from aqueous solutions of magnesium nitrate, and then impregnating the solid thus obtained with aqueous solutions of lithium carbonate or nitrate. Non-porous solids are obtained in all cases. Specific surface area development depends on the nature of the precursors, the MgO→Mg(OH)2→MgO process being topotactic.

    Description / Table of Contents: Abstract Описывают термическое разложение прекурсоров катализаторов Li/MgO, приготовленных их различных соединений Mg и Li. Помимо разложения LiNO3, а не Li2CO3, в обоих случаях наблюдается дегидратация и дегидроксилирование. Свойства твердых веществ коррелируют с плавлением и распределением LiNO3 или Li2CO3 на поверхности перед или после дегидроксилирования Mg(OH)2.
    Notes: Abstract The thermal decomposition of precursors of Li/MgO catalysts prepared from different Mg and Li compounds is reported. Dehydration and dehydroxylation is observed in both cases, in addition to decomposition of LiNO3, but not of Li2CO3. The properties of the solids are related to the melting and spreading of LiNO3 or Li2CO3 before or after Mg(OH)2 dehydroxylation.
