    Description / Table of Contents: Abstract При давлении до 100 бар исследован синтез аммиака на нитридах CeN, UN1, 70 и железном катализаторе CA-1. Кинетика реакции описывается уравнением Темкина-Пыжова. Энергия активации для всех образцов близка и составляет около 200 кДж/моль. Удельная каталитическая активность нитридов уступает железному катализаторы: 3–4 раза для урана и в 10 раз для церия.
    Notes: Abstract Ammonia synthesis on nitrides CeN, UN1.70 and iron catalyst CA-1 has been examined at pressures of up to 100 bar. Reaction kinetics is described by the Temkin-Pyzhev equation. Activation energy for all samples is similar and equals about 200 kJ/mol. Specific catalytic activity of nitrides is lower than that of the iron catalyst by a factor of 3–4 for uranium and 10 for cerium.

    Description / Table of Contents: Abstract Проведены измерения скоростей десорбции азота14N2 с поверхности нитридов в присутствии и отсутствии молекул15N2 в газовой фазе. Показано, что независимо от теплоты адсорбции и атомности поверхностных частиц адсорбция молекул15N2 не влияет на скорость десорбции14N2.
    Notes: Abstract The rates of14N2 desorption from the surfaces of nitrides have been measured in the presence and absence of15N2 in the gas phase. Whatever the adsorption heat and the form of surface species, the adsorption of15N2 molecules does not affect the rate of14N2 desorption.

    Description / Table of Contents: Abstract Измерена энергия активации Ea выхода кислорода из керамики YBa2Cu3O7-δ для значений δ от 0 до 0,2. Показано, что в интервале δ от 0,006 до 0,15–0,18 кислород достаточно однороден и характеризуется Ea=(36±3) ккал/моль. Изучены температурные зависимости низкополевого сигнала ЭПР этих керамик на частоте 9,3 КГц вблизи Tc.
    Notes: Abstract The activation energy Ea of oxygen evolution from the YBa2Cu3O7−/gs ceramics has been measured for σ ranging from 0 to 0.2. In the σ range from 0.15 to 0.18 oxygen is fairly homogeneous and its evolution is characterized by Ea=(36±3) kcal/mol. Temperature dependence of a low-field ESR signal of the ceramics have been studied at a frequency of 9.3 KHz nearby TC.
