Comparative Studies on Photoelasticity of Elastomers and Plastomers

Rubber Chemistry and Technology, 1948
Abstract Transparent films of elastomers and plastomers were found to differ sufficiently in their photoelastic behavior to make stress double refraction a useful criterion of the prospective mechanical properties of a given material. The stress double refraction in such films is mostly an effect of deformation, of orientation, or of both ...

Plastomes of Betulaceae and phylogenetic implications

Journal of Systematics and Evolution, 2019
AbstractBetulaceae is a well‐defined family of Fagales, including six living genera and more than 160 modern species. Species of the family have high ecological and economic value for the abundant production of wood. However, phylogenetic relationships within Betulaceae have remained partly unresolved, likely due to the lack of a sufficient number of ...

Plastomes of Bryophytes, Lycophytes and Ferns

2012
We review current progress in our understanding of chloroplast genomes (plastomes) of liverworts, mosses, hornworts, lycophytes and monilophytes. We briefly cover some of the methods used to obtain complete nucleotide sequences of plastomes and we summarize the published sequences from the plant groups above. We explore some of the evolutionary changes

Mentallocane plastomer modification of polypropylenes

Polymer Engineering & Science, 2001
AbstractPlastomers are ethylene alpha‐olefin coplymers made from the single site metallocdene catalyst using a variety of polymerization processes. The key features are uniform intermolecular and intermolecular comonomer distribution, low extractables, comonomer dependent. meleting point, and low ashcontent. The uniform comonomer behavior.

Plastome Mutants of Higher Plants

2012
This chapter provides an overview of higher plant plastome mutants and their application in molecular biology, cytoplasmic genetics and biotechnology. Starting from an outline on plastid inheritance, the sources of mutants, methods of their maintenance and molecular approaches to identify the underlying genetic changes are presented.
