Method for Doping Nanocrystals Could Up Efficiency of Solar Panels

A team of researchers have demonstrated how semiconductor nanocrystals can be doped in order to change their electronic properties and be used as conductors. This opens a world of possibilities for applications of small electronic and electro-optical devices, such as diodes and photodiodes, electric components in cellular phones, digital cameras, and solar panels.

Will 3D laptops catch on?

Last week, Toshiba unveiled a glasses-free 3D laptop, the Qosmio F750. The screen displays 2D and 3D simultaneously in separate windows. The display uses a lenticular lens sheet, capable of sending slightly different images to the left and right eye separately, thus giving the user a sense of image depth. The computer has a high-definition webcam that tracks a user's eyes and consequently shifts the image that is displayed. Some customers are excited for the expanded 3D capabilities, while others say that the technology is buggy and a three-dimensional feature is unnecessary. What do you think? Will 3D laptops catch on?

Will we avoid a mass marine extinction?

This week's Question: In a preliminary report from the International Programme on the State of the Ocean, a scientific panel concluded that ocean degeneration is happening much faster than previously predicted, and that the combination of factors currently distressing the marine environment is contributing to the exact conditions that have been associated with all major extinctions in the Earth's history: an increase of both hypoxia (low oxygen) and anoxia (lack of oxygen that creates "dead zones") in the oceans, warming, and acidification. The researchers warn that the combination of these factors will inevitably cause a mass marine extinction if swift action isn't taken to improve conditions. What do you think? Will we avoid a mass marine extinction?

Capturing and Using Waste Heat from Cars, Factories, and Power Plants

New technology is being developed at Oregon State University to capture and use the low-to-medium grade waste heat from automobiles, diesel generators, or factories and electrical utilities. The new systems should be able to use much of that waste heat either in cooling or the production of electricity.

Neutron Analysis Explains Dynamics Behind Thermoelectric Materials

Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory (ORNL) gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity.
