Hydrazine monopropellant reciprocating engine development [PDF]

open access: yes
A hydrazine fueled piston engine for providing 11.2 kW was developed to satisfy the need for an efficient power supply in the range from 3.7 to 74.6 kW where existing nonair-breathing power supplies such as fuel cells or turbines are inappropriate.

A Simplified Polymerization Model for Fluorinated Polymers: Average Microstructural Properties and Recipe Optimization

open access: yesPolymer Engineering &Science, EarlyView.
A model‐based strategy for the design of the emulsion polymerization recipe for a fluoroelastomer, namely Tecnoflon, is reported. This ensures target average microstructural properties like number‐average molecular weight, number of iodine end‐groups and number of bridges per chain can be obtained and preserved all along the reaction.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
