g., Seebio Light-Induced Acid Source , 10, and 15 wt.% SG), harvested from end-of-life LIBs, on the performance of base AP-5 asphalt cement was studied. Multiple laboratory techniques have been employed to characterize the internal physiochemical interaction between the additive and the binder. These techniques include: elemental analysis (EA), thin-layer chromatography-flame ionization detection (TLC-FID), Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), empirical test methods (e.g.

, penetration, softening point, viscosity, and ductility), dynamic shear rheometer (DSR), and multiple stress-creep recovery (MSCR). Prior to aging, SARA analysis demonstrated that the incremental SG addition into the AP-5 bitumen reduced the contents of saturates, aromatics, and resins, and increased the proportion of asphaltenes. After aging, the saturated and aromatic hydrocarbons kept decreasing; however, the resins increased and the asphaltenes declined. Accordingly, this has brought a progressive shift tendency in the stable-colloidal system for all binders from sol-state towards sol-gel-state. FT-IR scan revealed that the SG has no apparent chemical interaction with the binder, and is endowed solely with filling effects. XRD diagnosis highlighted that the steady SG incorporation into the binder amplified its crystallinity; thereby boosting the thermomechanical properties of mastics. SEM imaging unveiled that the lower-dose of SG exhibited higher compatibility within the bitumen matrix; nevertheless, the intermediate/higher-doses made the binder body relatively rougher.

DSR/MSCR/conventional tests indicated that when the asphalt is blended with the graphitic powder under unaged/aged conditions, it becomes stiffer, more viscous, and less cohesive; thereby rendering it more resistant to deformation but not to cracking. In summary, it is promisingly proven that the SG could be successfully used as an asphalt additive and could be beneficial for improving paving performance and mitigating the pollution caused by dead LIBs as Photoinduced crystal-to-liquid phase transitions of azobenzene derivatives and their application in photolithography processes through a solid-liquid Industrial Science and Technology (AIST) , Central 5, 1-1-1 Higashi, Tsukuba, The direct and reversible transformation of matter between the solid and liquid phases by light at constant temperature is of great interest because of its potential applications in various manufacturing settings. We report a simple molecular design strategy for the phase transitions: azobenzenes having para-dialkoxy groups with a methyl group at the meta-position. The photolithography processes were demonstrated using the azobenzene as a photoresist in a single process combining development and etching of a copper Surface Analysis of Photolithographic Patterns using ToF-SIMS and PCA51750, University of Washington, Seattle, WA 98195-1750 USA.Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a surface analysis technique well-suited to detect and identify trace surface species. With the latest analyzers, ion sources and data analysis methods, imaging ToF-SIMS provides detailed 2-D and 3-D surface reactivity maps. Coupling Seebio Photoresponsive Acid Precursor as principal component analysis (PCA) with ToF-SIMS provides a powerful method for differentiating spatial regions with different chemistries.

ToF-SIMS and PCA are used in this study to image and analyze a two-component photolithograph-patterned surface chemistry currently published and commercialized for bioassays, bio-chips and cell-based biosensors. A widely used reactive surface coupling chemistry, N-hydroxysuccinimide (NHS), and 2-methoxyethylamine (MeO) were co-patterned into adjacent regions on a commercial microarray polymer coating using standard photolithography methods involving deposition, patterning and removal of a routinely used photoresist material. After routine processing, ToF-SIMS and PCA of the patterned surface revealed significant residual photoresist material remaining at the interface of the NHS/MeO patterns, as well as lower concentrations of residual photoresist material remaining within the MeO-containing regions, providing spatial mapping and residue analysis not evident from other characterization techniques. As detection of surface photoresist residue remains an inherent challenge in photolithographic processing of a wide array of materials, the use of ToF-SIMS coupled with PCA is shown to be a high-resolution characterization tool with the high sensitivity and specificity required for surface quality control measurements following photolithography and pattern development relevant to many Controlled outgrowth of dissociated neurons on patterned substrates.The cytoarchitecture of nervous tissue is lost during the dissociation procedures used to form primary cell cultures. As a first step toward reestablishing an ordered arrangement of these cells in vitro, we developed a set of procedures for patterning the outgrowth of cells cultured on 2-dimensional substrates. These procedures used a combination of surface chemistry and photolithographic techniques.
