Laser-ablated aluminum atoms react with dinitrogen on condensation at 10 K to form N3 radicals and the subject molecules, which are identified by nitrogen isotopic substitution, further reactions on annealing, and comparison with isotopic frequencies computed by density functional theory. The major AlN3 product is identified from three fundamentals...

... 80% of the GaN 3 product is formed from the N 3 radical reaction. 10 NAlN. The strong 656.9 cm 1 band also increased on annealing and decreased markedly on photolysis. This band showed a small 14 N 2 / 15 N 2 ratio 1.01782 and an approxi- mate 1:2:1 triplet pattern with 14 N 2 14 N 15 N 15 N 2 , which is characteristic of two equivalent N atoms Fig. 3 AlNAl. The 956.7 cm 1 band increases slightly on an- nealing but almost doubles on photolysis. The mixed isotopic spectra reveal a doublet absorption Fig. 2 for the vibration of a single nitrogen atom and a large 1.02683 nitrogen 14/15 isotopic ratio. In fact the 14/15 isotopic ratio for the harmonic antisymmetric vibration of a linear ...

Background and Motivation: Nitrogen content in tissues of Fagus crenata Blume is key for flowering and seed production. However, there is a lack of information on seasonal intra-plant nitrogen partitioning in this representative tree species typical of heavy snowfall regions in Japan. Therefore, the objective of this study was to elucidate Fagus cr...
Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different energetic requirements that might be reflected in their trophic ecology. We analyze bulk tissue and w...

Coordination of a strong σ-base has been shown to be an effective method for the stabilization of low valent main group element complexes. This general method was now used for the synthesis of the divalent germanium diazide. IPrGe(N3)21 represents the first neutral homoleptic germanium diazide that could be structurally characterized.
Research on materials at high temperatures under equilibrium as well as under kinetic conditions poses a high
challenge for any scientist. The investigations of the properties are limited either by the sample holding container or by
the instrumentation that should analyze the significant information. Thermodynamic investigation in equilibrium state
with the Knudsen effusion mass spectrometer (KEMS) and thermal analysis (DTA/TG/DSC) in quasi equilibrium state at
temperatures beyond 1000 °C are main and standard topics in our lab.
This article will introduce measurements on aluminum nitride (AlN) as a potential material for application in
microelectronics, electronic substrates, chip carriers where high thermal conductivity is essential, and light emitting
diodes (LED).
The current knowledge about azides of the heavier Group 13 elements is reviewed. Only neutral compounds of the general formula R3−xM(N3)x(D)y and MN3 (M=Al, Ga, In, Tl; R=organic or inorganic substituent; D=neutral donor; y=0–3) are taken into account. The syntheses of Group 13 azides of the formal oxidation number +III can either be achieved by salt metathesis, σ bond metathesis, or substitution reactions. The synthesis, structures, properties, and applications of mono-, di-, and triazides including inter- and intramolecular donor-stabilized compounds are discussed.
