The repetitive discoloration kinetics of the azo-dye Methyl Orange (taken as a model organic compound) was followed under solar simulated radiation (90 mW/cm2) to assess the performance of the TiO2/Tedlar® composite photocatalyst. The influence of solution ...
The surface plasmon polariton-enhanced Raman spectra of size-selected C16, C18, and C20 clusters isolated in nitrogen matrices are presented along with the calculated vibrational frequencies for the ring and linear chain isomers. The Raman spectra, recorde ...
The investigation of H-1-H-1 spin-diffusion build-up curves using a rate matrix analysis approach shows that high-resolution magic angle spinning NMR of protons, applied to powdered organic compounds, provides a method to probe crystalline arrangements. Th ...
The surface plasmon polariton-enhanced Raman spectra of size-selected, matrix-isolated C14 neutral clusters are presented along with the calculated vibrational frequencies for the ring and linear chain isomers. The Raman spectra show resonance enhancement ...
Upon deprotonation using trimethylsilylmethylpotassium or butyllithium in the presence of potassium tert-butoxide, two allylic organopotassium species are generated from the (E)-isomeric caryophyllene and the (Z)-isomeric isocaryophyllene. Torsional equili ...
A novel application of vibrational sum frequency generation (VSFG) is developed to study the molecular properties of the surface of submicron particles in suspension. The Rayleigh-Gans-Debye scattering theory is extended to extract the local molecular resp ...
The synthesis of 46 derivatives of (2R,3R,4S)-2-(aminomethyl)pyrrolidine-3,4-diol is reported (Scheme I and Fig. 3), and their inhibitory activities toward alpha-mannosidases from jack bean (B) and almonds (A) are evaluated (Table). ne most-potent inhibito ...
Crystals of hexamethylenetetramine (HMT) with aliphatic dicarboxylic acids in 1:1 molar ratio exhibit different behaviour depending on the number n of carbons in the aliphatic chain. For n=8 and 10, incommensurate phases have been observed, while for n=9, ...
The emergence of antimicrobial resistance has led to an increase in research directed toward the engineering of novel polyketides. To date, less than 10 000 polyketide structures have been discovered exptl.; however, the theor. anal. of polyketide biosynth ...
Organic light emitting devices (OLED) are among the most promising future technologies for the manufacture of flat and inexpensive displays. Although OLEDs provide already much higher brightness as compared to liquid crystals devices (LCD), they have a maj ...
