Summary
This study introduces "chemical stripes," a tool visualizing historical chemical patent data. It helps assess past chemical use impacts and predict future trends, despite data limitations.
Area of Science:
- Chemistry
- Data Science
- Environmental Science
Background:
- Historical chemical usage data is vital for health and environmental impact assessments.
- Past monitoring data is often limited, hindering comprehensive analysis.
- Cheminformatics offers solutions for analyzing historical chemical information.
Purpose of the Study:
- To introduce and detail the "chemical stripes" tool for visualizing chemical patent and literature trends.
- To explore the utility of patent data in understanding historical chemical usage patterns.
- To assess the potential and limitations of data-driven methods for chemical trend analysis.
Main Methods:
- Developed an interactive, open-source tool called "chemical stripes."
- Utilized patent data from PubChem, focusing on origins, uses, and countries.
- Integrated cheminformatics, statistical analysis, and data visualization techniques.
Main Results:
- Visualized trends in chemical patents over time and across different geographic regions.
- Identified both opportunities and potential artifacts in patent data extraction.
- Demonstrated the value of integrated data analysis for historical chemical insights.
Conclusions:
- Chemical stripes provide valuable insights into the historical landscape of chemical patents.
- Data-driven cheminformatics methods, despite caveats, can illuminate past chemical usage.
- This approach can serve as an early warning system for future chemical trends and regulatory needs.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH...

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

The protons in unsubstituted alkanes are strongly shielded with chemical shifts below 1.8 ppm. Methine, methylene, and methyl protons appear at approximately 1.7, 1.2 and 0.7 ppm, while the proton signal from methane appears at 0.23 ppm. An electronegative substituent, such as chlorine, withdraws the electron density from the protons, increasing their chemical shift. Progressive substitution of the hydrogens in methane by chlorine shifts the proton signals increasingly downfield, to 3.05 ppm in...
