Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Scavenger Sodium Ions in Field Effect Transistors
Sodium ions which are present in polymers drift under applied fields. If
these ions are permitted to diffuse into field-effect transistors (FETs), the FETs
no longer function properly.
It is very difficult to obtain solution-cast polymers which do not have any
sodium contamination. It is therefore desirable to have a technique whereby the
sodium contamination in a polymer will not cause degradation of FETs.
Multidentate, macrocyclic materials, such as crown ethers and cryptands, can
complex alkali metals. By incorporating such materials into polymers which are
used with FETs, the ability of any sodium ions to migrate is reduced. These
materials can be incorporated into the polymer either as a separate entity or as
part of the polymer chain.
