The establishment of a simple and effective method for determination of heavy metal ions has great significance due to the high hazard of heavy metal ions to public health and environments. Herein, we developed a facile way to synthesise a nanocomposite comprised of carbon nanotubes (CNTs) and metal-organic frameworks (MOFs), and explored its application in constructing an electrochemical (EC) sensor for detection of Cd2+ in aqueous solutions. The sensing surface was simply fabricated by casting...

Potential antecedents to having a sense of purpose in life remain understudied. As researchers begin contemplating purpose as a promising target of public health intervention, it is critical to identify its antecedents. Using prospective data from the Nurses’ Health Study II (2009–2016; N ranged from 3,905 to 4,189), this study evaluated a wide range of potential antecedents of purpose, including psychosocial well-being, psychological distress, employment characteristics, lifestyle, and physical health factors. In separate regression models,...
