Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...
For my students I shall consider in detail distributions defined by the principal value and the finite part of divergent integrals. I shall also consider continuity properties of distributions defined by holomorphic functions.
Biomass-derived chemicals can offer unique chemical functionality relative to petroleum-derived building blocks. To this end, here we report that ?-ketoadipic acid (?KA), a C6 diacid with ?-ketone group, be used as performance-advantaged replacement for adipic in nylon-6,6 analog. Building on our previous efforts produce shikimate-derived products from carbohydrates, Pseudomonas putida KT2440 i...
[This retracts the article on p. 272 in vol. 6, PMID: 28299270.].
ZIF-8 films were successfully prepared on a flexible nylon substrate with a contra-diffusion synthesis method, and gas permeation experiments indicated that the films were continuous and compact.
