Associations between rest-activity/light-exposure rhythm characteristics and depression in United States adults: A population-based study.

This cross-sectional study investigated the association between 24-hour rest-activity rhythm (RAR), light exposure rhythm (LER), and depression symptoms in American adults, using data from the National Health and Nutrition Examination Survey (2011-2014, N = 6852). RAR and LER characteristics were derived from a 24-hour activity recorder and analyzed using the extended cosine model, focusing on intradaily variability (IV), interdaily stability (IS), and relative amplitude (RA). Depression was assessed via the Patient Health Questionnaire-9 (PHQ-9).

The association between fat distribution and α1-acid glycoprotein levels among adult females in the United States.

Background: Visceral fat accumulation and obesity-induced chronic inflammation have been proposed as early markers for multiple disease states, especially in women. Nevertheless, the potential impact of fat distribution on α1-acid glycoprotein(AGP), a marker of inflammation, remains unclear. This research was conducted to investigate the relationships among obesity, fat distribution, and AGP levels.

Direct Regenerating Cathode Materials from Spent Lithium-Ion Batteries.

Recycling cathode materials from spent lithium-ion batteries (LIBs) is critical to a sustainable society as it will relief valuable but scarce recourse crises and reduce environment burdens simultaneously. Different from conventional hydrometallurgical and pyrometallurgical recycling methods, direct regeneration relies on non-destructive cathode-to-cathode mode, and therefore, more time and energy-saving along with an increased economic return and reduced CO footprint. This review retrospects the history of direct regeneration and discusses state-of-the-art development.

Perovskite-derived structure modulation in the iron sulfate family.

We report the first example of a perovskite sulfate [Na(HO)]Fe(SO). Further structure modulation, by dimensional reduction or ligand extension, has resulted in two related layered perovskite-like compounds NaFe(SO) and NaFe(SO)F. Taken together, these results open up a more general strategy for the future design of more complex perovskite-related materials.

Synthesis, Structure, and Electrochemical Properties of Some Cobalt Oxalates.

Transition-metal oxalates have wide applications in magnetics, photoemission, electrochemistry, etc. Herein, using hydrothermal reactions, five cobalt(II) oxalates, NaCo(CO)·2HO (), NaCo(CO)·8HO (), KLiCo(CO) (), LiCo(CO) (), and (NH)Co(CO)F () have been synthesized, and their structures are determined from single-crystal X-ray diffraction or Rietveld refinement of powder X-ray diffraction data. Notably, and are identified for the first time.

Mixed Polyanionic Compounds as Positive Electrodes for Low-Cost Electrochemical Energy Storage.

Low-cost electrochemical energy storage systems (EESSs) are urgently needed to promote the application of renewable energy sources such as wind and solar energy. In analogy to lithium-ion batteries, the cost of EESSs depends mainly on charge-carrier ions and redox centers in electrodes, and their performance is limited by positive electrodes. In this context, this Minireview evaluates several EESS candidates and summarizes the known mixed polyanionic compounds (MPCs)-a family with robust frameworks and large channels for ion storage and migration.
