During February 25-26, DoD will culminate its Black History Month observance with the outreach activities planned by AAMU, according to Clarence A. Johnson, principal director of DoD’s Office of Diversity Management and Equal Opportunity.
DoD's Theme for the month of February "Reaching Out to Youth: A Strategy for Excellence." Accordingly, all DoD organizations and agencies are being urged to conduct events and activities in observance of Black History Month. The two-day DoD observance will begin Wednesday, February 25, with a 10 a.m. technical assistance workshop in the Learning Resources Center auditorium designed to provide university administrators and students information on obtaining surplus equipment, contracts and grants.
The session will end at 5 p.m. The culminating event of the first day is a welcome and awards ceremony at 7 p.m. in the Ernest 20 L. Knight Reception Center .
The ceremony will host historically black college and university (HBCU) presidents and administrators; local government officials; and community members and organizations. It will also recognize military award recipients engaged in the global war on terrorism. This event is sponsored by Team Redstone. The DoD/HBCU Leadership Symposium has been scheduled for Thursday, February 26, from 8-11 a.m. in the Clyde Foster Multipurpose Room of the School of Business . Senior DoD officials and HBCU presidents will discuss critical minority representation issues.
Two concurrent sessions also will run from 9-11:30 a.m. on Thursday. A student exposition for middle and high school students will be held in the auditorium of the School of Engineering and Technology. The session will include presentations about opportunities for appointments at service academies, ROTC entry, and civilian careers. Students will also have a chance to tour exhibits. A similar college student career symposium will be held in the Dawson Building auditorium. Additional exhibits will be located in the Ernest L. Knight Reception Center on Wednesday and Thursday. The joint DoD-AAMU Black History Month observance will conclude with a luncheon in the Ernest L. Knight Reception Center at 12 noon for HBCU officials and students.

Study findings from Alabama A&M University broaden understanding of crystallography
Alabama A&M Univeristy is one of the leading research institutions in crystal growth. Below are published findings reported in the June 2008 edition of Vertical News:
2008 JUN 23 - (VerticalNews.com) -- According to recent research from the United States, "Cesium cerium bromide (CS2CeBr5) and potassium cerium bromide (K2CeBr5) are new scintillator materials for X-ray and gamma ray detector applications. Recently, halide scintillator materials such as Ce-doped lanthanum bromide have been proved to be very important materials for the same purpose."
"These materials are highly hygroscopic; a search for high-light-yield non-hygroscopic materials was highly desirable to advance the scintillator technology. In this paper, we are reporting the crystal growth of novel scintillator materials, CS2CeBr5 and K2CeBr5. Crystals were successfully grown from the melt using the vertical Bridgman-Stockbarger technique. In comparison with the high-performance LaBr3 or LaCl3 crystals, cerium-based alkali halide crystals, CS2CeBr5 and K2CeBr5, have similar scintillation properties, while being much less hygroscopic. Furthermore, cesium-based compounds will not suffer from the self-activity present in potassium and lanthanum compounds. However, the CS2CeBr5 crystals did not grow properly probably due to non-congruent melting or some phase transition during cooling," wrote R. Hawramia and colleagues, Alabama A&M University.
The researchers concluded: "Published by Elsevier B.V."
Hawramia and colleagues published their study in the Journal of Crystal Growth (New scintillator materials (K2CeBr5 and CS2CeBr5). Journal of Crystal Growth, 2008;310(7-9 Sp. Is):2099-2102).
For additional information, contact R. Hawramia, Alabama A&M University, Dept. of Physics, Normal, AL 35762, USA.
