Nanoscale zero-valent iron (NZVI) particles were investigated in inactivating gram-positive Bacillus subtilis var. niger and gram-negative Pseudomonas fluorescens bacteria, and the fungus Aspergillus versicolor. NZVI particles were synthesized using NaBH(4) and Fe(NO(3))(3).9H(2)O, and the microbial suspensions were subjected to the treatments of NZVI(More)
Formation of cirrus clouds depends on the availability of ice nuclei to begin condensation of atmospheric water vapor. Although it is known that only a small fraction of atmospheric aerosols are efficient ice nuclei, the critical ingredients that make those aerosols so effective have not been established. We have determined in situ the composition of the(More)
Are phased array antennas the future of atmospheric radar technol-ogy? This is a question many scientists and radar engineers ask today. The purpose of this article is to discuss some technical aspects and review progress in the development of phased array technology that can help us understand the current state of weather radar, the needs of the radar(More)
