A team of researchers has developed a groundbreaking one-step, crystal growth process for making ultra-thin layers of material with molecular-sized pores. Researchers demonstrated the use of the material, called zeolite nanosheets, by making ultra-selective membranes for chemical separations. These new membranes can separate individual molecules based on shape and size, which could improve the energy-efficiency of chemical separation methods used to make everything from fuels to chemicals and pharmaceuticals.

Bonding Chips Using InkJet Printers

A team of researchers at the University of Barcelona have demonstrated a new bonding technique for surface mounted devices that uses an inkjet printer with ink that incorporates silver nanoparticles. The technique, described this week in the Journal of Applied Physics, was developed in response to the industrial necessity for a fast, reliable and simple manufacturing process, and with an eye to reducing the environmental impact of the standard fabrication processes.
