Nanotechnology allows the synthesis of nanoscale catalysts, which offer an efficient alternative for fuel cell applications. In this laboratory experiment, the student selects a cost-effective anode for fuel cells by comparing three different working electrodes. These are commercially available palladium (Pd) and glassy carbon (GC) electrodes, and…

Advocates an increase in the use of coal to alleviate the oil and gas shortage. Outlines present deterrents which limit the exploitation of coal, and discusses ways in which this energy source might be more effectively utilized. (JR)

Prospects for microbial technology are discussed including: (1) possible transfer of nitrogen-fixing ability directly from bacteria to plant; (2) increasing food needs met through single-cell proteins and fermentation; (3) microbial production of antibiotics; and (4) increased biogas production.
