Pi in the Sky: Another Simple Trick

“The trick is growing up without growing old.” -- Casey Stengel (American Baseball Player and Manager, 1891-1975)
Searching for technical literature on pi complexation – an important key phrase in desulfurization research – can be tricky.  That’s because searching for “pi complexation” yields a different set of results than searching for “π complexation.”

To illustrate … when we search Google scholar for articles containing “pi complexation” in the title, the result is 52 hits …












 Desulfurization of transportation fuels by [pi]-complexation sorbents: Cu (I)-, Ni (II)-, and Zn (II)-zeolitesAJ Hernandez-Maldonado, FH Yang, G Qi… - Applied Catalysis B: …, 2005 - Elsevier
New π-complexation-based sorbents were studied for desulfurization of diesel, gasoline,
and jet fuels. The sorbents were obtained by ion exchanging faujasite type zeolites with
Cu+, Ni2+ or Zn2+ cations using different techniques, including liquid phase ion exchange ...

Perform the same search using “π complexation” and the result is 92 hits.

Desulfurization of liquid fuels by adsorption via π complexation with Cu (I)-Y and Ag-Y zeolitesAJ Hernández-Maldonado… - Industrial & engineering …, 2003 - ACS Publications
Fixed-bed adsorption using different π-complexation adsorbents for desulfurization of liquid
fuels was investigated. Cu (I)-Y (autoreduced Cu (II)-Y), Ag-Y, HY, and Na-Y zeolites were
used to separate low-concentration thiophene from mixtures including benzene and/or n- ...

So how do you search for “π“ (the symbol) vs. “pi” (the word)?

Here’s a simple trick








Open Word
Click the Insert tab
Click the Symbol icon
Locate and click the “π” symbol
Select the “π” symbol that appears in your Word document
Copy it to your clipboard
Go to your Google Scholar window and paste the “π” symbol into the search box
Add the word “complexation”

That’s it.  Simple, yet effective.  That’s the kind of tips and tricks we like to provide in the Desulfurization Blog (www.desulf.blogspot.com). Here’s another simple trickadd the Blog as a feed on your organization’s Web for a continuing stream of useful tips.
