In the beginning, like attracts like to make a dimer. Nobel Prizes are a rich source of dimers. I counted twenty-three Nobel Lectures with dimers. The wealth in dimers can compound a case not only in biochemistry but also in organic chemistry. A new certainty sparkles here with a metal form, the beryllium dimer. 
A new study conducted by scientists in France concludes that the alluring eye makeup worn by ancient Egyptians also may have been used to help prevent or treat eye disease by doubling as an infection-fighter. The study appears in the January 15 issue of Analytical Chemistry.

The researchers note that thousands of years ago the ancient Egyptians used lead-based substances as cosmetics, including an ingredient in black eye makeup. Some Egyptians believed that this makeup also had a "magical" role in which the ancient gods Horus and Ra would protect wearers against several illnesses. Until now, however, modern scientists largely dismissed that possibility, knowing that lead-based substances can be quite toxic. 
Separation science has seen glamour and growth with ever-increasing demand for analysis ranging from environmental, toxicological to forensics. The list is endless and the genre is getting narrower for the graduates. Considering these points, eminent professors and research scientists have rolled out a wonderful interface for evolving pedagogy.      
separationsNOW marks and celebrates chromatography education through webinar series, " Year of Education in Separation Science."
It is fascinating and interesting interface to ask generic to advanced questions. I was intrigued by the idea and would love my graduate class to learn afresh. I would love to challenge the age-old universal method of teaching.
That's right, my love for the periodic table can now be extended to my phone! My sweet Palm Pre features the periodic table in its app catalog, with such data as:

  • Oxidation Status

  • Boiling Point

  • Melting Point

  • Electron Configuration

  • Electron Negativity

  • Atomic Radius

  • Atomic Volume

  • Specific Heat Capacity

  • Ionization Potential

  • Atomic Number

  • Symbol

  • Name

When Dmitri Mendeleev first published his table of elements in 1869 (picture), only 60 of these were known. One group in particular was absent, namely the inert gases.  Now you may have heard this song:

"All these gases are inert
  Helium, neon, argon.
I’ll sing this song until it hurts
  Krypton, xenon, radon." **
Scientists say they can now tell the condition of an old book by its odor. In a report published in Analytical Chemistry, a team of researchers describe development of a new test that can measure the degradation of old books and precious historical documents on the basis of their aroma. The non-destructive "sniff" test could help libraries and museums preserve a range of prized paper-based objects, some of which are degrading rapidly due to advancing age, the scientists say.

The new technique — an approach called "material degradomics" — analyzes the gases emitted by old books and documents without altering the documents themselves. The scientists used it to "sniff" 72 historical papers from the 19th and 20th centuries.
Did someone mention Elvis? This research made the cover of ACS's Journal of Physical Chemistry in color. 
All you need is a pic-a-nic basket and wine in Erlenmeyer flasks.

Sustainability stretches through greener chemistry. Imagine having a choice in designing environmentally friendly materials. This opportunity is presented in "Identifying the Molecular Origin of Global Warming" scheduled for the November 12's ACS Journal of Physical Chemistry. The approach taken by Partha Bera et al. seeks to explain how fundamental properties influence molecular absorption in the atmospheric window. What are the major factors that make some molecules more effective greenhouse gases (GHGs)?
