Modeling the self-assembly of nano objects: applications to supramolecular organic monolayers adsorbed on metal surfaces. This work is expected to create a significant impact on the development of an orthogonally correlated spectroscopic tool in deciphering chemical insights and underlying reaction mechanism. Comparison between normal and SERS spectra of ATP isomers supports the fact that additional disulfide- or hydrogen-bonding interactions are established in para-ATP solid crystal, but neither of ortho- nor meta-isomers. The correlative measurement shows that ortho-substitute barely formed a self-assemble monolayer, relative to the para-isomer, which can form a close-packed self-assembled monolayer and perform a decent azo-coupling reaction. We distinguished the different self-assembling behavior of isomeric aminothiophenols (ATPs) on Ag dendrite by the correlation of surface-enhanced Raman spectroscopy and laser-induced desorption ionization mass spectrometry, demonstrating that steric effect impinged significantly upon surface molecular density and plasmon-driven catalytic reaction yield, which led to drastic variations in the resulting SERS spectra. 987-93.Correlated spectroscopic analysis can provide complementary chemical insights that are often unattainable by either approach used in isolation.

The shape and location of deformation bands estimated from the FEM simulations were well matched with the experimental observations.Ī. The finite element method (FEM) analysis based on real microstructures was also conducted to theoretically explain the enhanced elongation in terms of effective dendrite size. Since the wide and homogeneous deformation in this sheet beneficially worked for the tensile strength and elongation simultaneously, the optimum effective dendrite size (12.1 μm) and sheet thickness (3 mm) were determined for the Ti-based amorphous matrix composite. According to the observation of tensile deformation behavior of the 3-mm-thick composite sheet, many deformation bands were formed inside dendrites in several directions, and deformation bands met crossly each other to form widely deformed areas. pct of dendrites sized by 9 to 27 μm, and showed excellent tensile properties of yield strength of 1.3 GPa and elongation up to 6.5 pct. These composite sheets contained 72 to 75 vol. Five composite sheets having different thicknesses were fabricated by varying cooling rates after a vacuum arc melting of a Ti-based amorphous matrix composite fabricated by adding alloying elements of Ti, Zr, V, Ni, Al, and Be into a Ti-6Al-4V alloy. ![]()
