• 5-aminosalicylic acid

    Updated: 2012-06-30 22:12:26
    This drug is taken as an anti-inflammatory to manage some bowel diseases. The maximum dosage is around 4000mg/day, but if someone were to overdose with 8000mg/day for a week, which organ(s) would be affected by this? Would the skin be affected in any way? Also, would the damage be reversible?I would try to answer this question myself, but I don't know anything about this compound's method of action, or how it interacts with the body. Any help would be appreciated.

  • Re: Why is the ppm of stock solution different from ICP result?

    Updated: 2012-06-30 22:05:25
    That's the thing...I know that the solution should be 1000ppm based on what I did etc.But the ICP is giving me data that says my stock (1000 ppm) solution is really a 100 ppm solution... therein lies the problem. I must figure out the problem before proceeding.

    QuoteI made a stock solution of Re2O7 in DI water and adjusted the pH to 2 using sulfuric acid. The addition of 1.3g of the rhenium (VII) oxide to the 1L of water should have given me a solution that is 1000ppm Re.With data given above all is OK

  • Smokey Mountains of Colorado

    Updated: 2012-06-25 21:40:30
    Last evening the layers of mountain valleys to the west and north were filled with smoke from the High Park fire west of Ft Collins, Colorado. The valleys full of haze reminded me of the Smokey Mountains of Kentucky in the evening. The fire is 25 miles as the crow flies from my house. The prevailing winds have [...]

  • Microscopic Printing on Aldrich Chemical Labels

    Updated: 2012-06-22 00:37:12
    OK. I’m going to have to be the bad guy and take Aldrich (SAFC) to task on their labeling. I recently received a 100 mL bottle of 10.0 M BuLi in hexanes.  As I looked around for the concentration, I found it written in tiny print away from the name and part number which were written in [...]

  • ChemSpider Magic with LASSO

    Updated: 2012-06-21 01:25:17
    Of late I have been concerned with R&D information and various homebrew means of storing it and retrieving it. Institutionalizing R&D results into easily accessed knowledge can roll into a real hairball if you’re not careful. More on that another time. My adventures with CHETAH 9.0 have caused me to look deeply into SMILES strings and what [...]

  • Chemistry in its element – titanium dioxide

    From the Chemistry Reddit, a TedED animation by Aaron Sams describing 5 ways to increase the rate of a chemical reaction. I'm not following all the analogies, but it's still a pretty good teaching tool.

  • Glucose Fuel Cell for Medical Implants

    Updated: 2012-06-14 17:40:54
    Professor Rahul Sarpeshkar and colleagues at MIT have created an implantable fuel cell which relies on glucose as its fuel. The device could potentially be used as a power source for the computers needed to decode brain signals and manipulate prosthetic or perhaps paralyzed limbs. The article was published in PLos ONE. There are many [...]

  • Chemistry in its element – potassium nitrate

    Updated: 2012-06-14 11:49:45
    The saltpetre men of the 17th century could be described as the first biochemists. But they could also be described as a ‘rowdy and undesirable’ lot, hated and feared for the disruption and distress they caused in their search for their precious namesake. Lars Ohrstrom tells the story of potassium nitrate in this week’s Chemistry in its element [...]

  • CT Scans. Who is monitoring a patient’s radiation dose?

    Updated: 2012-06-13 14:05:38
    The matter of medical x-radiation dosing is surfacing again. I wrote a post about this in 2009. Let’s get to the core of the matter. Physicians need to take charge of this since only they have any real control. It’s a pretty goddamned simple concept. Doc’s who are calling for x-ray’s need to begin recording calculated [...]

I won’t repeat all of it, but a few good points stand out. Carroll began the talk by highlighting the differences [...]

    I hope folks out there had a chance to view the transit of Venus across the solar disk yesterday.  I was lucky enough to see it through a 6 inch refractor and a Coronado H-alpha solar telescope. It’s always fun to see celestial mechanics in operation. NASA has a video of the transit acrosst the [...]

  • Chemistry in its element – carbon tetrachloride

    Updated: 2012-06-06 14:02:22
    At its height, it was as an all-purpose cleaner, refrigerant and even fire extinguisher but we have since learned (the hard way) that it is dangerously toxic. Brian Clegg charts the downfall of carbon tetrachloride in this week’s Chemistry in its element podcast.

    Updated: 2012-06-04 06:24:48
    One of the fun things you can do with uranium is to turn big atoms into little atoms.  All natural heavy nuclei will undergo fission after a hard enough kick (for instance, protons accelerated to around 50 MeV will fission gold or bismuth), but to split uranium, all you need are some household-variety neutrons.  Offering [...]
