Startup turns carbon dioxide into fuels - 1 views

  • Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.
  • Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.
  • Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.

  • Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.
  • The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.

PSA: Don't Let Salami and Google Images Get You In Hot Water -Edublogs - education blogs for teachers, students and institutions - 130 views

  • This is a true story.
  • Three years ago, an eleven-year-old blogger here on Edublogs wrote a post about his favorite lunch food – salami.
  • Our Edublogs support team just received a lengthy cease and desist letter from a large law firm that represents the photographer of the salami photo.
  • ...3 more annotations...
  • As part of his post, he used Google Images to find a quick photo of salami that he then uploaded to his blog.
  • What does this mean for teachers and students?
  • Using Google Images or copying a photo from most websites is much like plagiarism. Hopefully, by educating each other, we can avoid mistakes like this one and promote fair use of photos and other media on the web.
  •  
    Shared this with my students and we decided to create a class Diigo library of public domain images to help reduce everyone's legwork. It takes a little while longer to find pictures, but it's worth it.

Contextual Analysis- Uganda (Sarita Vengal) | International Field Program Seminar-Spring '11 - 11 views

  • Food and grocery stores definitely plays an important role in this community. There were also an unexpected amount of African art and music stores. I think diaspora communities like this have a lot of meeting and community aid establishments to help immigrants navigate the American system of living.
    • Fabiola Berdiel
       
      Very insightful contextual analysis
  • I honestly didn’t see too many advertisements outside of the West African diaspora context. The ads that I did see were not billboards or real advertisements. There were mostly posters or small signs showcasing the sales in each of the stores.
  • As a native New Yorker, who grew up in an Indian diaspora community, I felt like a lot of the sights resonated with my childhood.  And to make things even more familair, I lived in Niger for a few months and did feel a certain connection to the area.

Bloom's Taxonomy Blooms Digitally, Andrew Churches - 33 views

  • In the 1950's Benjamin Bloom developed his taxonomy of cognitive objectives, Bloom's Taxonomy. This categorized and ordered thinking skills and objectives. His taxonomy follows the thinking process. You can not understand a concept if you do not first remember it, similarly you can not apply knowledge and concepts if you do not understand them. It is a continuum from Lower Order Thinking Skills (LOTS) to Higher Order Thinking Skills (HOTS). Bloom labels each category with a gerund.
  • In the 1990's, a former student of Bloom, Lorin Anderson, revised Bloom's Taxonomy and published this- Bloom's Revised Taxonomy in 2001.Key to this is the use of verbs rather than nouns for each of the categories and a rearrangement of the sequence within the taxonomy. They are arranged below in increasing order, from low to high.

      I like that the revised version is ongoing. Eileen Tobin
  • Each of the categories or taxonomic elements has a number of key verbs associated with it Lower Order Thinking Skills (LOTS) Remembering - Recognising, listing, describing, identifying, retrieving, naming, locating, finding Understanding - Interpreting, Summarising, inferring, paraphrasing, classifying, comparing, explaining, exemplifying Applying - Implementing, carrying out, using, executing Analysing - Comparing, organising, deconstructing, Attributing, outlining, finding, structuring, integrating Evaluating - Checking, hypothesising, critiquing, Experimenting, judging, testing, Detecting, Monitoring Creating - designing, constructing, planning, producing, inventing, devising, making

Tom Wolfe, Author and Satirist of America, Dies at 88 | Time - 4 views

  • American maverick who insisted that the only way to tell a great story was to go out and report it.
  • journalism could offer the kinds of literary pleasure found in books.
  • Wolfe scorned the reluctance of American writers to confront social issues and warned that self-absorption and master’s programs would kill the novel. “So the doors close and the walls go up!” he wrote in his 1989 literary manifesto, “Stalking the Billion-Footed Beast.” He was astonished that no author of his generation had written a sweeping, 19th century style novel about contemporary New York City, and ended up writing one himself, “The Bonfire of the Vanities.”

  • “My contention is that status is on everybody’s mind all of the time, whether they’re conscious of it or not,”
  • “new journalism” combined the emotional impact of a novel, the analysis of the best essays, and the factual foundation of hard reporting. He mingled it all in an over-the-top style that made life itself seem like one spectacular headline.
  • pointed look at fund-raising for the Black Panther Party by Leonard Bernstein and other wealthy whites.
  • And no one more memorably captured the beauty-and-the-beast divide between the Beatles and the Rolling Stones: “The Beatles want to hold your hand,” he wrote, “but the Rolling Stones want to burn down your town!”
  • s a child, he did rewrites of the Authurian legends and penned biographies of his heroes.
  • unsuccessful pitching tryout with the New York Giants before
  • The Washington Post, where he won Washington Newspaper Guild awards in 1960 for his coverage of U.S.-Cuban affairs and a satiric account of that year’s Senate civil rights filibuster.
  • The next year, Wolfe was assigned to cover a “Hot Rod & Custom Car” show. He completed a story, the kind “any of the somnambulistic totem newspapers in America would have come up with.” But he knew there was a much richer, and longer story to tell, one about a thriving subculture that captured the post-World War II economic boom and the new freedom to “build monuments” to one’s own style. No newspaper could contain what Wolfe had in mind, so he turned to Esquire magazine, wrote up 49 pages and helped give birth to a new kind of reporter. “For the who-what-where-when-why of traditional journalism, he has substituted what he calls ‘the wowie!'” according to a 1965 Newsweek story.
  • “A Man in Full” turned Wolfe’s smirk to Atlanta society. His 2004 novel, “I Am Charlotte Simmons,” looked at life on a fictional elite college campus rife with drinking, status obsession and sex.
