The influence of Mo particle size on the catalytic activity and product selectivity of alkalized MoS2 nanocatalysts has been investigated. Nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. Three different techniques, including XRD, TEM, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

OBJECTIVE To develop a Web-based tool (PortionSize@warenessTool) and to evaluate its effectiveness in increasing awareness of reference serving sizes and factors that may contribute to overeating in response to large portion sizes. METHODS A randomized, controlled trial (intervention, n = 167; control, n = 143) was conducted. The authors measured awareness of reference serving size and overea...
