Phase Change-Mediated Capture of Carbon Dioxide from Air with a Molecular Triamine Network Solid.

The efficient removal of CO from exhaust streams and even directly from air is necessary to forestall climate change, lending urgency to the search for new materials that can rapidly capture CO at high capacity. The recent discovery that diamine-appended metal-organic frameworks can exhibit cooperative CO uptake via the formation of ammonium carbamate chains begs the question of whether simple organic polyamine molecules could be designed to achieve a similar switch-like behavior with even higher separation capacities. Here, we present a solid molecular triamine, 1,3,5-tris(aminomethyl)benzene (TriH), that rapidly captures large quantities of CO upon exposure to humid air to form the porous, crystalline, ammonium carbamate network solid TriH(CO)·HO (TriHCO).

Digital food marketing (DFM) of unhealthy foods and beverages (high in saturated fats, sugar and salt) to children and young people influences brand recall, recognition, purchase intentions and attitudes, and increases consumption of unhealthy foods and beverages. Understanding children's and parents' awareness of, and attitudes toward, such marketing is crucial for developing health-promoting advocacy and policy solutions. This registered systematic scoping review synthesized literature on children's, young people's and parents' attitudes and awareness of DFM.

Importance: In 2013, the Trial to Assess Chelation Therapy (TACT) reported that in 1708 patients with stable coronary disease and prior myocardial infarction (MI), oral multivitamins and multiminerals (OMVMs), in a factorial design with edetate disodium (EDTA) chelation therapy, did not reduce cardiovascular events relative to placebo OMVMs, but active EDTA combined with active OMVMs was superior to placebo OMVM/placebo EDTA.
Objective: To compare OMVM vs placebo in terms of efficacy for reducing major adverse cardiovascular events in patients with diabetes and prior MI.
Design, Setting, And Participants: The TACT2 randomized, multicenter double-masked 2 × 2 factorial clinical trial took place across 88 sites in the US and Canada.
Direct Mass Measurements of Neutron-Rich Zinc and Gallium Isotopes: An Investigation of the Formation of the First r-Process Peak.

The prediction of isotopic abundances resulting from the rapid neutron capture process (r process) requires high-precision mass measurements. Using TITAN's on-line time-of-flight spectrometer, first time mass measurements are performed for ^{83}Zn and ^{86}Ga. These measurements reduced uncertainties, and are used to calculate isotopic abundances near the first r-process abundance peak using astrophysical conditions present during a binary neutron star (BNS) merger.
