TRANSCRIPT
REDUCING GREEN HOUSE GAS EMISSIONS WITH A MORE EFFECTIVE CARBON CAPTURE METHODA comparison of the information from the article “Alkali Metal Nitrate-Promoted High-Capacity MgO Absorbents for Regenerable CO2 Capture at Moderate Temperatures” when presented in the original journal and when presented through a popular science website.

INTRO
Review of affect of Greenhouse Gases
Introduces idea of “trapping carbon dioxide”
Allusion to journal article
Doesn’t discuss reason why this is still important or current systems until content paragraph
Jumps right into the discussion of why carbon capture and storage (CCS) systems are still necessary
Quote amount of CO2
still being released Introduces the
downfalls of current systems
ScienceDaily Chemistry of Materials
PROBLEMS WITH CURRENT SYSTEMS
Two sentences summarize main problems with commonly used CCS systems.
“Some solid systems that aim to capture these emissons, such as zeolites, are sensitive to water in the gas streams.”
“…clays and metal oxides, have to be heated up to more than 900 degrees Fahrenheit…”
ScienceDaily
PROBLEMS WITH CURRENT SYSTEMS Explains more options
than just the two examples given by ScienceDaily specifically liquid and aqueous options
Goes in depth regarding the theoretical amounts of CO2 that is capable.
Highlights the compromise that materials that take less energy to work, store less but materials that store more, require more energy.
Chemisty of Materials
RESULTS
Dilutes results down to percentages and easy to compare numbers and sentences
Relates the better efficiency to what that means for Businesses
Showcases graphs and compares MgO without alkali metals to MgO with alkali metals
Lists the experimentally found results
Discusses trend lines and the rates of the CO2 absorbtion
ScienceDaily Chemistry of Materials
MISSING ASPECTS
Could include why MgO with alkali metals works better than just MgO
Discussion of the chemical reaction occurring in the experiment
How the change of temperature affected absorption (transition state from solid to liquid)
Could have included in discussion or last few sentences of conclusion, easy to understand percentages or direct comparisons to understand how much better this could potentially be
ScienceDaily
Chemistry of Materials
VOICE/VOCABULARY
Quotes the article often- includes authors names and from what University they are from
Describes the problems in easy to understand way and why it is a problem
Compares using percents and “2-10 times” instead of listing numbers
Lists experimental data
Uses chemical names Technical Language Assumes basic
chemistry knowledge and understanding of why CO2 is bad for environment
Alludes to equations
ScienceDaily Chemistry of Materials
FOCUSES OF WEBSITES
Summarizes articles for quick searches and links them in the summary for quick research
Posts multiple articles a day, all day.
Focuses on “Depth and Breadth” of information
“showcasing the top science news stories”
“publication of original on forefront, fundamental research … Both theoretical and experimental studies which focus on the preparation or understanding of materials with unusual or useful properties are relevant.”
