Researchers in California report a key advance in efforts to use inkjet printing technology in the manufacture of a new generation of low cost, high-performance electronic circuits for flexible video displays and other products. Their study* describes development of a new method for producing straighter, uniform circuits using inkjet-printing.

In the report, Dan Soltman and Vivek Subramanian note that inkjet-printed circuits must be extremely smooth and straight. That difficult feat has been elusive because the drop-by-drop nature of inkjet-printing often leaves uneven printed features on surfaces, especially a circular pattern known as the "coffee ring" effect, they note.

The scientists describe a new way to optimize printing conditions to eliminate the coffee-ring effect and produce smooth, narrow lines with an even edge. The development demonstrates the feasibility of tuning and optimizing inkjet technology for microelectronic applications, they say.

*The article "Inkjet-Printed Line Morphologies and Temperature Control of the Coffee Ring Effect" is scheduled for the March 4 issue of ACS' Langmuir.

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
