Welcome to the sixth comic in the Boil's Laws comic strip series, brought to ChEnected by artist and chemical engineer Rich Byrnes.

This is an arbitrary list. The only criteria: inciting that giddy feeling when a technological object elegantly solves a problem, wrapped in beautiful design.

Daniel M. Kammen, the World Bank Group's Chief Technical Specialist for Renewable Energy and Energy Efficiency, speaks to ChEnected at the E3-2010 Conference.

Tax decisions can affect chemical engineers as they take their projects from the lab to the field. Learn more about how you can learn to make wise tax-related decisions that will please your boss and bolster your project's success.

Researchers, students, government officials, and nonprofit and business leaders from Minnesota and across the nation attended E3 2010, Tuesday, November 30 at the Saint Paul RiverCentre. This year’s conference focused on the intersection among innovative technologies and policies, environmental benefits, and emerging market opportunities in the renewable energy sector.

This month, CEP covers the topic of sustainability through eco-efficiency analysis and brings you a look at the subjects of chromatography for separating complex mixtures and heat integration for improved energy efficiency.

AiChE young professionals attending the 2010 Annual meeting in Salt Lake City took in a football (i.e., soccer) game in their free time.

Commercial aviation just reached an important milestone. Germany's Lufthansa Airlines has announced they will begin using a biofuel blend for regularly scheduled passenger service starting in April. This six-month trial on Hamburg to Frankfurt flights is part of a long-term study of a 50-50 biofuel blend on flight performance, maintenance and engine life. One caveat: only one of the two engines will use the blend; the other will still rely on pure jet fuel.

Why does your bo$$ talk about things like inventory control when he asks you about operating costs? Inventory is the aggregate of items that are either held for sale in the ordinary course of business, in the process of production for sale, or currently consumed in the production of goods or services to be available for sale in the future.

Before working for an upstream oil company, I was under the impression that chemical engineers working in oil and gas belonged in pipeline and downstream operations. For those of you not in the industry, most large, integrated oil companies consist of an upstream organization and a downstream organization. The former focuses on exploration and production and the latter refines crude petroleum into usable products (gasoline, lubricants, etc.).
