RATIONALE Rapidly performing global proteomic screens is an important goal in the post-genomic era. Correlated matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and fluorescent imaging of photocleavable peptide-coded random bead-arrays was evaluated as a critical step in a new method for proteomic screening that combines many of the advantages of MS with fluorescence-base...
In this study, ANSYS finite element software is used to simulate the temperature and stress field in the laser powder deposition process. The model is used to determine the effect of the deposition pattern on the final stress distribution. Four deposition patterns are defined to cover the same area: long bead, short bead, spiral in, and spiral out. The results show that the deposition pattern s...
Polydispersity is inevitable in industrially produced polymers. Established theories of polymer dynamics and rheology, however, were mostly built on monodisperse linear Dynamics polydisperse polymers yet to be fully explored—specifically how chains different lengths affect the one another a mixture. This study explored bidisperse melts using molecular bead–spring chain model. Binary mixtures be...
In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...
The purpose of this study was to evaluate LC Bead LUMI™ (40-90µm and 70-150µm) in order to determine if their increased resistance to compression influences microsphere penetration and distribution compared to more compressible commercial microspheres. LC Bead LUMI™ 40-90µm and 70-150µm, LC BeadM1® 70-150µm, Embozene™ 40µm and Embozene™ 100µm size and distributions were measured using optical m...
Two coarse-grained models for polymer chains in dense glass-forming polymer melts are studied by computer simulation: the bond fluctuation model on a simple cubic lattice where a bond-length potential favors long bonds is treated by dynamic Monte Carlo methods, and a bead-spring model in the continuum with a Lennard-Jones potential between the beads is treated by Molecular Dynamics. While the d...
