Surface-enhanced Raman spectroscopy of DNA bases [PDF]
, 1986 A Raman microprobe has been used to measure the surface-enhanced Raman spectra of adenine, guanine, cytosine and thymine. Comparison of the SERS spectrum with solution spectra shows that some line positions are not influenced by the adsorption process ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Algebraic model of bending vibrations of complex molecules
Chemical Physics Letters, 1993 Abstract We introduce an algebraic model of coupled anharmonic benders capable of describing the complete spectrum and intensities of bending vibrations of medium size and large polyatomic molecules. We apply this model to the calculation of CH bends in C6H6. The model appears to describe the data well.

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.
