  • Re: carbon signal missing in my C13 spectrum..

    Updated: 2012-02-04 09:05:36
    With the quarternary carbons (like an internal alkyne), you often need longer relaxation and delay times in order to excite and relaxe these carbons respectively. What kind of relaxation and delay times are you running?I sometimes have problems with my carbons vanishing inside the solvent residual carbon peaks (for CD3Cl). It might be worth a quick zoom-in on those peaks just to make sure nothing is hiding in there:D

  • Respecting liquid hydrocarbons as a natural wonder

    Updated: 2012-02-03 23:51:09
    I just had a conversation with a colleague who is somewhat mainstream in his/her thinking. The question came up as to what can’t we be energy independent.  What is taking so long with the electric cars and natural gas powered … everything? When can we break away from middle eastern petroleum? In the public sphere, [...]

  • Pinch Predicted in the Uranium Market

    Updated: 2012-02-03 18:16:16
    According to an article in Mineweb, the remaining cold war era uranium will be consumed in the next few years, leaving the nuclear industry with inadequate supply streams from mining.  Thomas Drolet of Drolet & Associates Energy Services, said that in 2010 mining produced 118 million pounds of uranium against a demand of 190 million pounds.

  • Return to fundamentals

    Updated: 2012-01-26 19:29:51
    As we labor away on our extractive metallurgy project, I continue to marvel at how even complex extraction schemes reduce to the application of fundamental chemistry and basic unit operations. It is crucial to have a comprehensive understanding of the composition of your ore and the fate of the components as they are exposed to [...]

  • Chemistry in its element – carbon monoxide

    Updated: 2012-01-25 17:04:39
    In this week’s Chemistry in its element podcast, Duncan McMillan breathes life into carbon monoxide: a silent killer whose calling card is the ironically healthy hue of its victims. But, as Duncan explains, these days canary-based CO detectors are a thing of the past and we’re even learning that CO can be helpful [...]

    Updated: 2012-01-24 03:14:17
    Thanks to Bill in Michigan for the link on how the US lost out on manufacturing the iPhone. The article is well worth the read. A few of us have been beating this drum for a while. Economics is not a theory of physics. It is entirely about choices people make. But to some, economics has become [...]

  • Vannoccio Biringuccio. Sixteenth Century Chronicler of Metallurgy.

    Updated: 2012-01-16 06:17:20
    By the early 16th century in Europe, metallurgy had become an established cottage industry in numerous locales. Artisans were sourcing copper, tin, zinc, antimony and iron ores for reduction, refinement and alloy production for cannon and bells among other products.  While there was no systematic science of chemistry in a form recognizable today, the necessity of constant proportions [...]

    Devon Energy has raised $900 million in cash from Sinopec Group for a stake in Devon shale gas plays. These gas projects include the Utica, Niobrara, and Tuscaloosa formations.  What is interesting is not so much that China has bought its way into the extraction of a resource that the USA has in some abundance.
