Just One Word--Plastics

This is part of IEEE Spectrum's special R&D report: They Might Be Giants: Seeds of a Tech Turnaround.

Counting the number of plastic items around you is an exercise only a plastics industry executive could love. The material is ubiquitous--which is just what electronics manufacturers want their products to be when they talk of putting intelligence everywhere.

The word home evokes a sense of belonging and welcoming. IEEE aims to create a similar feeling by offering services for members at every stage of their career and by building a community among them.

IEEE President and CEO K.J. Ray Liu is committed to making IEEE the professional home for members. As he announced in his March column in The Institute, he’s doing that by “examining ways in which the organization could evolve to best meet the needs of all technical professionals in the years ahead.”

Home Heating With Hydrogen: Ill-Advised as it Sounds

Several studies reveal serious drawbacks

Hydrogen, if it comes from splitting water with renewable electricity, has its role as a climate-friendly energy source. It could help decarbonize challenging sectors like heavy industry, shipping, and aviation.

But hydrogen makes absolutely no sense for heating homes and buildings, according to a new review of several international studies. It is simply much too expensive and inefficient for that purpose, says Jan Rosenow, Europe director at the Regulatory Assistance Project, an energy think tank in Brussels, who authored the commentary published in the journal Joule.

Modeling Thermal Management Systems for Electronics

Learn how to model conjugate heat transfer in electronic devices with COMSOL Multiphysics

1 min read
Comsol

The ability to dissipate heat is one of the most important features of modern electronic devices and is usually a limiting factor in the miniaturization of these devices.

COMSOL Multiphysics includes functionality for heat transfer through conduction, convection, and radiation. Its ability to treat conjugate heat transfer, including laminar and turbulent flow as well as surface-to-surface radiation, has proven to be of great importance for the design and optimization of thermal management systems in electronics. Its multiphysics modeling capabilities also enable the study of thermoelectric effects as well as thermal–structural effects, such as thermal expansion.

In this webinar, we will demonstrate how to create models and apps for conjugate heat transfer in electronic devices. We will also give a general overview of the software’s capabilities for multiphysics modeling, including heat transfer as one of the modeled phenomena.
