Chance Present

A bit more Glitz & Glitter.
Still flirting with Lady Luck?
Still deciphering the game?
Or are we stuck in a marriage of convenience & philandering with a
quick fix that has no future...

Chance History @ SFO

Gaming machines from the mechanical age.
The gears and levers of luck.
Let us try our hand.
Let us shape in wood & steel & paint that mechanism that throws
fortune our way, those channels by which our present is shaped and our
futures re-alligned.
Let us build, and in building, let us approach an understanding of the
play.

Like bonding with Like

This bottle was stuck in the grate but the orange of it really wanted
to be with the orange of the resting barricade. Now it is content, and
they are peaceful.

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."

Abstract Image



"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 3dx2y2,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."
