TL;DR: In this article, the chemical state of fission Te released from ceramic fuels was studied by means of the thermochromatograph, and it was found that in inert atmosphere, the Te was released in the form of metal, but in the presence of oxygen, it readily reacted therewith to form TeO2.
Abstract: The chemical state of fission Te released from ceramic fuels was studied by means of the thermochromatograph. In inert atmosphere, the fission Te was found to be released in the form of metal, but in the presence of oxygen, it readily reacted therewith to form TeO2. The chemical state of I released from Te and TeO2 was also determined.

TL;DR: In this paper, the effect of high power (highvoltage) nanosecond pulses on the phase composition and chemical state of atoms of surface layers of sulfide minerals with different semiconductor properties (galenite, molybdenite, and sphalerite) is investigated by means of XPES.
Abstract: The effect of high-power (high-voltage) nanosecond pulses on the phase composition and chemical state of atoms of surface layers of sulfide minerals with different semiconductor properties (galenite, molybdenite, and sphalerite) is investigated by means of XPES. Common patterns and characteristic features of the structural phase transformations of sulfide surfaces under the pulsed energetic effect are the formation and growth of a surface layer by the nonstoichiometric sulfur-enriched sulfide phase and Zn and Mo oxides and hydroxides; the staged character of the transformation of sulfur atoms in the composition of galenite and sphalerite surface layers; and the stability of the chemical state of sulfur in the molybdenite composition and lead atoms in the galenite composition.

TL;DR: In this article, the trisbipyridyliron(II) cation and ferricyanide form a crystalline precipitate with the formula [Fe(bipy)3]3[Fe-(CN)6]2,1-3H2O] and were used to study the chemical effects of the 68Fe(n,γ)59Fe reaction.
Abstract: The trisbipyridyliron(II) cation and ferricyanide form a crystalline precipitate with the formula [Fe(bipy)3]3[Fe-(CN)6]2,1–3H2O. Samples of this complex, separately enriched with 58Fe in each complex ion, were used to study the chemical effects of the 68Fe(n,γ)59Fe reaction. The initial distribution of 59Fe-activity as well as the thermal annealing pattern are nearly the same for the two samples. This indicates that nearly all bonds to the recoiling 59Fe are broken, and that the ultimate chemical form of the 59Fe depends more upon the properties of the lattice than upon its original chemical state.

TL;DR: In this article, a modified borosilicate glass was synthesized by incorporating CaO, TiO2 and Al2O3 to the primary glass forming constituents and on melting the mixture at 1373-1473K/3h by melt quench method.
