Commercial high-power and narrow linewidth mid-infrared lasers make it possible to efficiently separate the two stable isotopes of 11B and 10B using the method of selective laser assisted retarded condensation (SILARC). However, a significant issue t

1-(4-Fluorobenzoyl)-9H-carbazole (1) was synthesized, starting from 9H-carbazole and 4-fluorobenzonitrile, by Friedel–Crafts acylation, using boron trichloride to direct the substitution in 1-position. Single-crystal X-ray diffraction analysis unam

In this paper, we have discussed the synthesis of nanoscale silicoboron carbonitride (SiBCN) nanofibers by electrospinning of novel polyborosilazane precursor solutions, which were synthesized from boron trichloride, tris(dichloromethylsilylethyl)bor

Borazine rings act as a pivotal part in siliconboroncarbonitride ceramics (SiBCN) for high-temperature stability and great resistance to crystallization. A detailed investigation of the ring formation mechanism will guide the design and synthesis of
