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

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.”
