The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

Angle of repose and angle of internal friction are two important macroscopic parameters in characterizing granular materials and reliable flow index in fluidization studies. This paper presents an experimental study to measure the angular properties, namely, angle of repose and angle of internal friction of lithium titanate (Li2TiO3) and silica particles. Lithium titanate is a primary contender for the solid breeder material for fusion reactors. Experimental results showed that the angle of repose of fine Li2TiO3 particles increases with increase in particle size, whereas the angle of internal friction decreases with increase in particle size. It was observed that the angle of repose varies in the range 31.7 to 35.62 deg, whereas angle of internal friction varies in the range 74.3 to 76.3 deg. A relationship between angle of repose and angle of internal friction for Li2TiO3 has been established. These results are useful to understand the flow characteristics of Li2TiO3 particles in a gas fluidized bed.
