This study extends Flory’s 1941 foundational work on three-dimensional step-growth polymerization (SGP) with trifunctional branching units. Flory laid the groundwork for understanding polymer size distribution back then, however, he did not fully explore the polydispersity and/or average degree of polymerization in A2 + A3 and A2 + A3 + B2 types of systems. As the demand for advanced three-dimensional

An extended SAXS quantitative model incorporating a diffuse interface was developed in this study to analyze the SAXS data of polyethylene and its copolymers with varying comonomer contents. The structural characterization was performed on one high-density polyethylene (HDPE) and three ethylene copolymers with similar molecular weights and distributions. Results showed that while copolymers have a

Mass cytometry is a powerful, high-throughput single-cell analysis technique that uses metal-tagged antibodies detected via inductively coupled plasma time-of-flight mass spectrometry. Current reagents use metal-chelating polymers (MCPs) for hard metal ions, but expanding to soft metal ions could significantly improve multiplexing. However, high nonspecific binding and poor water solubility have been

A fully automated robotic synthesizer for the screening of amphiphilic block copolymer (BCP) nanoparticle synthesis is presented. To reach this aim, BCP solutions are mixed in continuous flow with water, allowing for the automated variation of overall polymer concentration, mixing ratio of the water and organic solvent phase, and the overall flow rate of the system. Particle sizes are monitored online

Low-voltage organic field-effect transistors (OFETs) are of great significance for realizing low power-consumption electronics, where increasing the dielectric constant of gate dielectrics is an effective strategy to achieve low-voltage operation. Herein, a series of polyampholyte dielectrics with pendant phosphocholine zwitterionic groups are synthesized, and their applications in OFET devices are

PET has a wide range of applications in human life. To address the issues including low glass transition temperature, inadequate oxygen barrier properties, and slight brittleness that limit certain applications of PET, 1,4-cyclohexanedimethanol (CHDM) and isosorbide (IS) were incorporated into the PET main chains using a one-pot two-step method, resulting in the formation of PETGI copolymers. Dynamic
