Harnessing the Power of Spinach

Vanderbilt University researches have developed a way to combine Photosystem 1 (PS1), the photosynthetic protein that converts light into electrochemical energy in spinach with silicon (the material used in solar cells), in a fashion that produces substantially more electrical current than has been reported by previous biohybrid solar cells.

Starting Point for Overcoming Barrier to Fusion Power

The accuracy of a new model for predicting the size of a key barrier to fusion power, which was developed by physicist Robert Goldston of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been confirmed. Goldston’s model predicts the width of what physicists call the “scrape-off layer” in tokamaks, the most widely used fusion facilities.

The Future of Iron-Air Batteries

A University of Southern California research team has developed a cheap, rechargeable battery that could be used to store energy at solar power plants for a rainy day. The air-breathing battery uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air — a process similar to rusting.

Magnetics Design: Specification, Performance & Economics

An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.

New Tech for Grid-Level Electrical Energy Storage

Electrical energy storage is the obstacle preventing more widespread use of renewable energy sources. Due to the unpredictable nature of wind and solar energy, the ability to store this energy when it is produced is essential for turning these resources into reliable sources of energy. The current U.S. energy grid system is used predominantly for distributing energy and allows little flexibility for storage of excess or a rapid dispersal on short notice. Drexel University researchers believe they have a solution.

Ultra-Sensitive Biosensor for Medical Diagnostics

This device may enable miniaturization and new point-of-care applications in doctors' offices. Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and “personalized medicine” tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors, said Muhammad A. Alam, a Purdue Uni versity professor of electrical and computer engineering.

Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries

Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.
