Designing Novel Zn-Decorated Inorganic B12P12 Nanoclusters with Promising Electronic Properties: A Step Forward toward Efficient CO2 Sensing Materials

“…Similarly, Shakerzadeh et al investigated adsorption of phosgene gas on Al- and Ga-doped B 12 N 12 and B 16 N 16 nanoclusters . Decoration of metal is useful in order to enhance the effective role of these nanocages in NLO materials. , In addition, these nanocages exhibit a variety of applications such as field-effective transistors, storage devices, and magnetic nanoparticles …”

Preparation of Iron Fine Particles Coated with Boron Nitride Layers

“…20,21) Huo suggested that the FeB nanoparticles should be in a molten or quasi-liquid state at 1373 K, which is lower temperature than the melting point of the bulk FeB, so that N atoms from the atmosphere easily diffuse into the FeB ''catalyst'', and when they become supersaturated, BN is precipitated in a solid state. As Fe-B compounds were generated in the process of the reaction between B andFe 2 O 3 , 12) it is considered that BN in the sample I was generated through the decomposition of Fe-B compounds, following the VLS mechanism. In heating process, B powders probably reduced -Fe 2 O 3 nanoparticles to Fe, and excess B immediately react with the reduced Fe, resulting in a generation of FeB fine particles separated by a produced boron oxide.…”

“…The purpose of the present work is to understand the mechanism of BN formation by usingFe 2 O 3 or Fe nanoparticles as a catalyst. In our previous work, 12) the differential thermal analysis showed that BN was generated from B and -Fe 2 O 3 above 1473 K. In order to generate BN fully, the mixtures were annealed at 1573 K in the present work.…”

“…In our previous works, we have successfully fabricated Fe nanoparticles coated with BN layers by annealing a mixture of hematite (-Fe 2 O 3 ) nanoparticles and B powders at 1373 K in a nitrogen atmosphere. 12,13) In these methods, the metal nanoparticles behaved like a catalyst for BN formation.…”

Synthesis, magnetic and electrical properties of Fe-containing SiO2 nanocomposite

“…However, Fe particles in nano form have a high affinity for oxygen. Despite the reduction of their total magnetic moment, when dispersed in non-magnetic matrix or coating, several studies have been conducted to encapsulate these particles in silica [1,3], alumina [4], yittria [5,6], gold [7], carbon [8], boron nitride [9], and Fe 3 O 4 [10,11] in order to improve their stability, electrical and magnetic properties. Fe-silica nanocomposites are of particular interest because they have higher resistivity and this combined with the good magnetic properties of metallic Fe, makes them a good candidate for dielectric applications and could possibly be a good replacement material for ferrites.…”
