Astley's Amphitheatre and the early circus in England, 1768-1830 by Kwint, M

“…<p>Founded in Lambeth in 1768 by the ex-cavalry sergeant Philip Astley (1742-1814), Astley's was one of the first entertainments to mix traditional acrobatic feats with the new trick-riding in a ring, thus founding the modern circus. As the leading example of the artform, the permanent Amphitheatre just south of Westminster Bridge went on to be immortalised by Dickens and parodied by Punch, before closure in 1893. …”

Evolved P450 mutants as general oxidation catalysts by Harwood, LA

“…Improvements to a previous synthetic route, two routes based on a C(sp²)–C(sp²) bond disconnection and a final route constructing the aryl ring via Robinson annulation will be discussed. New methodologies including an intramolecular Heck cross-coupling and a Lewis acid catalysed coupling of furfuryl alcohols with silyl enol ethers will be presented.…”

Organic donor-acceptor cocrystals for multiferroic applications by Wang, Zongrui, Zhang, Qichun

“…The cocrystallization strategy has provided an efficient route to fulfill room temperature magnetoelectricity in single phase owing to the long-range ordered π-π stacking (donor-acceptor assembled) network, long-lived excitons (with μs lifetime), spin orders (±1/2 s pin) and charge transfer (CT) dipoles in the assembled crystal lattice. …”

Expedient synthesis of heterocycles and methyl sulfonyl compounds via C-X BONDS (X = O, N, S) construction by Jiang, Yaojia

“…In chapter 3, we have described two methodologies to synthesize multi-substituted pyridines from rhodium-catalyzed nitrene reaction and DBU-mediated ring opening of 2-allyl-2H-azirines. In chapter 4, we have described a radical strategy promoted by copper, oxygen and HPO(OEt)2 for the difunctionalization of alkenes to synthesize β-keto methyl sulfones; meanwhile, we have also demonstrated that alkynes could be directly undergo methyl sulfonylation to afford (E)-vinyl methyl sulfones through modification of the reaction condition.…”

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). …”
