Abstract: The present invention provides efficient processes for preparing brush polymers. In general, the process comprises three distinct reaction steps utilizing two separate catalysts. In the first step, the initiating compound comprising norbornene is contacted with a silane in the presence of a catalyst, thereby forming a silated intermediate. This silated intermediate is then contacted with a monomer in the presence of a catalyst via Group Transfer Polymerization (GTP). The resulting compound from GTP is contacted with a ring opening metathesis polymerization (ROMP) catalyst to prepare the brush polymer. Surprisingly, the brush polymers obtained from the above process are accessed in an efficient and rapid GTP methodology as compared to prior methods.

Abstract: Implementations described and claimed herein provide systems and methods for sampling particles from air. In one implementation, an inlet opening is defined in a proximal end of a cassette top, and the inlet opening has an inlet diameter. An internal surface extends along an airflow curve from the inlet opening to an internal cavity. A sampling substrate is formed by at least one grid attached to a filter. The sampling substrate is disposed in the internal cavity at an internal distance from the inlet opening. The inlet opening and the airflow curve of the internal surface generate an airflow of the air to the sampling substrate. The sampling substrate collects a set of the particles from the air, and the inlet diameter, the airflow, and the internal distance dictate a cutoff diameter of the set of particles collected from the air by the sampling substrate.

Abstract: The present document generally relates to additive manufacturing techniques for forming an article having a desired shape and other properties. More particularly, but not exclusively, in one embodiment a method for additive manufacturing an article includes adding a dispersant to an article forming material in the absence of binder to prepare a slurry or suspension including the material and the dispersant. The pH of the slurry may be adjusted to control the viscosity and/or coagulation rate of the slurry. The slurry may then be passed through an extrusion-based three-dimensional printing apparatus to form or print the article in a desired form or shape, and the article may thereafter be sintered. In one aspect, through control of the pH of the slurry, the viscosity and/or coagulation rate properties of the slurry may be tailored for use with different operating parameters of the extrusion-based three-dimensional printing apparatus.
