Azadihomocorannulene as a heptagon-embedded diradicaloid by Hamamoto, Yosuke, Wang, Weifan, Li, Yongxin, Ito, Shingo

“…The synthesis was achieved through a mechanochemical C(sp2)-H/C(sp3)-H coupling in the presence of sodium as a key reaction. Electron spin resonance studies revealed that the neutral azapentabenzodihomocorannulene adopts a singlet diradical (diradicaloid) ground state with a small singlet-triplet energy gap of 2.1 kcal/mol. …”

Magnetic levitation using neodymium magnets for vertical axis wind turbine (VAWT) II by Lai, Chunji

“…This project involved the design and fabrication of a test model vertical axis wind turbine, however as this experiment was carried out indoor without any wind condition, the author used a dc motor to simulate the wind required to spin the turbine. The advantage of this motor allows the author some control over the speed of the turbine. …”
