Nano-Zirconium Tungstate Reinforced Liquid Crystalline Thermosetting Composites with Near Zero Thermal Expansion

Autor: Michael R. Kessler, Yuzhan Li, Kristen Constant

One crucial factor limiting the performance of polymer matrix composites is their relatively high coefficient of thermal expansion (CTE), which impacts the dimensional stability of these materials. This report described the synthesis and characteriza

Tobacco use profiles by respiratory disorder status for adults in the wave 1-wave 4 population assessment of tobacco and health (PATH) study

Autor: Jamie Cordova, Ruth M. Pfeiffer, Kelvin Choi, Rachel Grana Mayne, Laura Baker, Jacqueline Bachand, Kristen Constantine, Sean Altekruse, Carolyn Reyes-Guzman

Publikováno v: Preventive Medicine Reports, Vol 30, Iss , Pp 102016- (2022)

Limited evidence exists on the association between electronic nicotine delivery systems (ENDS) and chronic respiratory disorders. This study examines the association of combustible tobacco and ENDS use with chronic respiratory disorders among US adul
