Journal Highlight
Machine learning is beginning to make a large impact in catalysis research, according to Bryan Goldsmith, Jacques Esterhuizen, and Jin-Xun Liu of the Univ. of Michigan, Christopher Bartel of the Univ. of Colorado Boulder, and Christopher Sutton of the Fritz Haber Institute of the Max Planck Society in their July AIChE Journal Perspective article, “Machine Learning for Heterogeneous Catalyst Design and Discovery.”

Catalyzing Commercialization: New System Freezes Food Faster at Lower Cost

July
2018
Catalyzing Commercialization
In the U.S., 70% of consumed food passes through a cold chain, an uninterrupted series of temperature-controlled storage and distribution activities. Globally, maintaining these cold chains consumes one-sixth of all electricity generated and produces 30 billion metric tons of CO2 per year. Traditional vapor-compression heat pumps have low efficiencies, use refrigerants with a high global warming impact, and are unable to provide dynamic cooling capacity. A new technology will dramatically change this picture by first complementing, and eventually replacing, vapor-compression cycles.

The ChE in Context
Nada Marie Anid
According to the U.S. Dept. of Energy’s (DOE) Advanced Manufacturing Office, manufacturing contributes almost $2.2 trillion per year to the U.S. gross domestic product and employs 9% of the nation’s workforce. For every dollar spent in manufacturing, $1.81 is added to the U.S. economy. Moreover, the manufacturing sector accounts for 30% of U.S. energy use and about 75% of all U.S. patents.
