In the title compound, C20H18BrN3O2, the central carbonyl group forms amine-N—H...O and hydroxy-O—H...O hydrogen bonds, which lead to two fused S(6) rings. The N-bound phenyl ring is coplanar with the five-membered ring to which it is attached [dihedral angle = 5.22 (18)°], but the dihedral angle [33.87 (17)°] between the terminal phenyl and bromobenzene rings indicates an overall twist in the molecule. In the crystal packing, molecules assemble into dimeric aggregates via C—H...π interactions.
This book titled Nanofiber Research - Reaching New Heights contains a number of latest research results on growth and developments on material fibers in nanoscale. It is a promising novel research area that has received a lot of interest in recent years. This book includes interesting reports on cutting-edge science and technology related to synthesis, morphology, control, self-assembly and prospective application of nanofibers. I hope that the book will lead to systematization of nanofiber science, creation of new nanofiber research field and further promotion of nanofiber technology. This potentially unique work offers various approaches on the implementation of nanofibers. As it is widely known, nanotechnology presents the control of matter at the nanoscale and nano-dimensions within few nanometers, whereas this exclusive phenomenon enables us to regulate and control novel applications with nanofibers. This book presents an overview of recent and current nanofibers fundamental, significant applications and implementation research worldwide. It examined the methods of nanofiber synthesis, types of fibers used and potential applications associated with nanofiber researches. It is an important booklet for research organizations, governmental research centers, academic libraries and R&D affianced in recent research and development of nanofibers.
The unique properties of bismuth subcarbonate nanomaterials provide benefits in remediation, pollution prevention, and efficient use of resources; however, the greatest contribution to green chemistry is likely to be the new manufacturing strategies available through nanoscience. Thus, the present overview mainly focuses on the synthesis of diverse bismuth subcarbonates nanostructures such as nanoparticles, nanotubes, nanoplates, nanosheets, hollow microspheres and microstructures resembles rose, sponge, flower and persimmon-like morphologies; and studied their photocatalytic activities to reveal the morphological features of the precursor. Moreover the wide characterizations of these materials using various spectroscopic and microscopic techniques; and the probable catalytic mechanism based on their diverse architectures were discussed.
