The effect of the polydispersity polystyrenes on dispersion through silicas having different morphologies (fully porous, core-shell particles and monoliths) was investigated. heights equivalent to a theoretical plate (HETP) those columns were measured for small molecule (toluene) series sizes in non-adsorbing conditions. contributions total HETP including determined experimentally. longitudinal...

Petro-derived commodity thermoplastics are relatively inexpensive, lightweight, and non-biodegradable materials, which can be readily molded at high temperatures into a range of products. The manufacturing such thermoplastic resins products has increased dramatically over the last 70 years. plastics based on polyolefins, polystyrenes, polyesters occupy largest share (80%) world's plastic market...

Enhancing the maturation of human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) will facilitate their applications in disease modeling and drug discovery. Previous studies suggest that cell alignment could enhance hPSC-CM maturation; however, the robustness of this approach has not been well investigated. To this end, we examined if the anisotropic orientation of hPSC-CMs imposed by t...

Adding depletants to a colloidal suspension induces an attractive interparticle interaction that can be tuned to obtain desired structures or to probe phase behavior. When the depletant is not uniform in size, however, both the range and strength of the attraction become difficult to predict and hence control. We investigated the effects of depletant bidispersity on the non-equilibrium phase be...

The criterion for brittle fracture of entangled polymer liquids [Wagner et al., J. Rheol. 62, 221–223 (2018)] is extended by including the effects finite chain extensibility and concentration. Crack initiation follows from rupture primary C–C bonds, when strain energy entanglement segments reaches covalent bond. Thermal fluctuations will concentrate on one bond segments, leading to scission cha...
