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. …”

Investigation on the braking characteristics of tractor-trailer on jackknifing by Gan, Zhilong

“…The results show that when the wheels remains in rolling motion, the brake input needs to be sufficient enough so as to inhibit the translational motion of the vehicle as well as work against the trailer swing motion or tractor spin-out. On the other hand, when the wheels are in sliding motion, the effective braking force exerted on the wheels is reduced and therefore increases the chance of jackknifing again. …”

Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging by Du, Wenya

“…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”
