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.

Method for Quantitative Determination of Organic Components in a
This method is a technique for determining the exact amount of plastici and
polymer in a ceramic mixture in the multilayer ceramic fabrication technology
without the need for extensive sample treatment.
In the multilayer ceramic technology, particularly that related to the
semiconductor packaging fabrication, understanding the performance
characteristics of the multilayer ceramic greensheet requires knowledge of its
composition at various times in the fabrication cycle. The ceramic mixture in the
fabrication cycle can exist as a slurry or as a greensheet at different
manufacturing states. Knowledge of the exact composition of the ceramic
mixture at these points in time is important. While analytic techniques for
separate analysis can be developed, they all require extensive sample treatment
to separate the inorganic phase from the organic.
In this method for determining the exact amount of an organic compound in a
mixture which includes other organic materials with or without inorganic materials (1) the sample is weighed, (2) the sample is heated to a temperature that
produces a vapor pressure of the organic compound to be measured for a time
sufficient to drive off the compound, (3) the remaining sample is weighed, (4) the
remaining sample is heated at a higher temperature to vaporize the second
remaining organic compound, (5) the sample is weighed, and (6) the weight
