Tech Front: Li-ion Battery Tech Leads to Hydrogen Production



Edited by Senior Editor Michael C. Anderson

8/1/2015

Developers of electric cars that used lithium-ion batteries are racing the champions of hydrogen-fueled vehicles to see which will succeed the greenhouse gas-producing gasoline-powered internal combustion engine. They’ve been racing in different directions—until now: Scientists at Stanford University have created a low-voltage, low-cost “water splitter” that uses a single catalyst to continuously produce both hydrogen and oxygen from water.

Tech Front: Big Fuel Cell Breakthrough is at the Nano Level



Edited by Advanced Manufacturing Media Staff

7/1/2015

A development in the real-time observation of fuel cell catalyst degradation could be the breakthrough that leads to the creation of more efficient and durable fuel cell stacks. Toyota Motor Corp. (Toyota City, Japan) and the the Japan Fine Ceramics Center (JFCC; Nagoya, Japan) have developed a new technique that allows monitoring of the behavior of nanometer-sized particles of platinum during chemical reactions in fuel cells. This allows the processes leading to reduced catalytic reactivity to be observed. Full Article

Laser Technologies Offer a Growing Array of Choices



Contributing Editor Bruce Morey

2015-05-01

Lasers first started making a significant impact for manufacturing in the early to mid 1970s. Since then, a number of advances, both evolutionary and revolutionary, have made lasers a common tool of choice for applications such as cutting, welding, drilling, brazing, and cladding. They are often easier to automate than many of their mechanical competitors. No moving part contacts the metal, so no tool wears out that needs replacement. Full Article

Tech Front: A New Way to Extract Hydrogen from Water



Edited by Senior Editors Patrick Waurzyniak and Ellen Kehoe

2015-05-01

Hydrogen is considered an important source of clean energy, and the cleanest way to produce hydrogen gas is to split water into hydrogen and oxygen. But scientists have struggled to develop cost-effective water-splitting techniques. Now, researchers at NC State University (Raleigh, NC) have created a technique using a new catalyst for converting methane and water into hydrogen and a fuel feedstock, called syngas, with the assistance of solar power.

Part of the Hole Story



Senior Editor Ellen Kehoe

2/26/2015

It couldn’t have been long after the first tools were hacked into shape that the first holes were made in some rock or tree. Fast forward many centuries and the first machine tool used by mechanically minded folks is likely a drill press. Everyone feels like an expert after making a perfect hole in something, but precision holemaking involves “many factors that must be considered regardless of how simple making holes might seem,” says the author of SME Technical Paper TP62PUB6.
