Improving the Physics of Grocery Store Display Cases to Save Energy

Designing grocery display cases has a lot in common with aeronautical engineering. Refrigerated display cases shoot jets of air across their front openings, creating an invisible shield that aims to keep cold air in and warm air out. Current technology does this with limited success. Engineers at the University of Washington and Kettering University have found that tweaking the physics can reduce energy by as much as 15 percent.

Technology Reduces Production Costs of Lithium-ion Cells

A development by engineers of Germany's Karlsruhe Institute of Technology (KIT) is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physicochemical effect that also provides water transport in trees. The new process increases the throughput of battery production and reduces investment costs.

Record-Breaking Solar Cells

Developed by Singapore's Nanyang Technological University (NTU) and A*STAR Institute of Microelectronics (IME), new thin-film silicon solar cells are designed to be made from cheaper, low-grade silicon. The nano-structured solar cells can produce a current of 34.3mA/cm2 – a world record for a silicon solar cell of its kind.

Novel Catalyst Helps Turn Carbon Dioxide Into Fuel

Artificial photosynthesis is the process of converting carbon dioxide gas into useful carbon-based chemicals - most notably fuel or other compounds usually derived from petroleum - as an alternative to extracting them from biomass. An Illinois research team has produced a catalyst that improves the process.
