New Blue Chromophore
Mn3+ in Trigonal Bipyramidal Coordination
"The researchers were trying to make compounds with novel electronic properties, mixing manganese oxide, which is black, with other chemicals and heating them to high temperatures.
Then Mas Subramanian, a professor of material sciences, noticed that one of the samples that a graduate student had just taken out of the furnace was blue."
-New York Times: Kenneth Chang
"We show that trivalent manganese, Mn3+, imparts an intense blue color to oxides when it is introduced at dilution in trigonal bipyramidal coordination. Our optical measurements and first-principles density functional theory calculations indicate that the blue color results from an intense absorption in the red/green region. This absorption is due in turn to a symmetry-allowed optical transition between the valence-band maximum, composed of Mn 3dx2−y2,xy states strongly hybridized with O 2px,y states, and the narrow Mn 3dz2-based conduction-band minimum. We begin by demonstrating and explaining the effect using a well-defined prototype system: the hexagonal YMnO3−YInO3 solid solution. We then show that the behavior is a general feature of diluted Mn3+ in this coordination environment."

Good News
"A Long Island deli owner who held a robber at gunpoint, then let him go after giving him $40 and a loaf of bread, says he got an anonymous letter from the crook that included a $50 bill and a thank-you for saving him from a life of crime.
The mysterious writer apologized to his would-be victim, Mohammad Sohail, saying, 'First of all I would like to say I am sorry at the time I had [no] money no food on the table no job and nothing for my family.'
Similar to comments he made on his knees during the incident last May, he said he realized that trying to rob the store with a baseball bat 'was wrong but I had [no] choice. I needed to feed my family.'"

Figs! Alla 'Fallen Fruit'
"'Public Fruit' is the concept behind the Fallen Fruit, an activist art project which started as a mapping of all the public fruit in our neighborhood. We ask all of you to contribute your maps so they expand to cover the United States and then the world. We encourage everyone to harvest, plant and sample public fruit, which is what we call all fruit on or overhanging public spaces such as sidewalks, streets or parking lots."
A Property Called Strange
"'The neutron and proton I believe you have already met. In the next row you have the sigma particle, which can manifest with both positive and negative electric charge and also with no charge at all. It consequently appears as if it were three different particles. In the center of the pattern you have the lambda, which is a single particle with no charge. These are all strange particles,' he added.
'They all seem very strange to me, ' agreed Alice, as she came over to look at them more closely.
'No, no. Strangeness is simply a property possessed by certain particles and which happens to have been given the name of strangeness. Rather like electric charge, you know—except that it is totally different,' he added unhelpfully. 'The remaining two particles are both the Cascade. It comes in tow different charge states, so there are two of it,' he explained. 'it is double strange, of course.'
'Of course,' echoed poor Alice."

Holiday Shopping?
Curated by Glen Helfand and Rebecca Bollinger
A temporary art space is created in the Alameda Shopping Center.
Graduate Students from CCA create unique and unusual shopping experiences for mall-goers.
People dance... sculpt globes... trade a can of food for a porcelain sculpture of a can... draw zombies... and much much more!
