An oxygen generation core-shell structure uploading rose bengal has been fabricated by covalent assembly of catalase and alginate dialdehyde via Schiff's base. The composite can catalyze the decomposition of intracellular H2O2 to increase the concentration of O2, which effectively enhances the anticancer efficiency of photodynamic therapy in vitro.
The 1,3-distal cone-calix[4]arene dialdehyde 1 undergoes Cannizzaro disproportionation in the presence of strong base, but its 1,2-vicinal regioisomer 3 and the analogous monoaldehyde 2 are unreactive under the same conditions. The high intramolecular reactivity of the 1,3-distal regioisomer 1 is measured and discussed in terms of Effective Molarity (EM).
The pungent principle of myoga (Zingiber mioga Roscoe) was identified as (E)-8beta(17)-epoxylabd-12-ene-15,16-dial (miogadial) on the basis of its physical and spectroscopic properties (MS, NMR, IR, and UV). Galanal A and B, isolated as well as miogadial, had no hot taste. Reduced miogadial also was tasteless. The pungency of miogadial depended on the presence of alphabeta-unsaturated-1,4-diald...
Properties of propagation modes for a layered ZnO/XZ LiNbO3 surface acoustic wave sensor have been investigated both theoretically and experimentally. By calculating the effective permittivity function, it was shown that after the ZnO deposition two distinct propagation modes have been generated: a Rayleigh and a shear horizontal. A layer of InOx was deposited to provide a conductometric sensin...
