Volcano-Shaped Relationship Between Interfacial K-HO Ratio and CO Reduction Activity in Tandem Electrocatalysts.

Modulating surface-active hydrogen (*H) supply represents a critical strategy to boost the electrocatalytic CO reduction reaction (ECRR), yet the mechanistic interplay between *H dynamics and catalytic behavior remains ambiguous. Herein, we construct tandem catalysts (M/NiNC, M = Fe, Co, Cu, or Mn) by coupling tetranuclear metal clusters (M) with single-atom Ni sites on N-doped carbon (NiNC) to regulate *H supply. Experimental and theoretical results reveal that the *H supply is governed by both thermodynamics and kinetic factors.

Stability of Self-Reported Same-Sex and Both-Sex Attraction from Adolescence to Young Adulthood.

This study examined how sexual attraction varied across age, gender of participant, and gender of romantic partner, from adolescence to early adulthood. Comparisons between same-sex and both-sex attracted individuals were of particular interest. Using the National Longitudinal Study of Adolescent Health (AddHealth), we examined the responses of participants who reported experiencing same-sex attractions or both-sex attractions at least once within four waves (n = 1889).

Overnight Custody Arrangements, Attachment, and Adjustment Among Very Young Children.

Large numbers of infants and toddlers have parents who live apart due to separation, divorce, or nonmarital/noncohabiting child-bearing, yet this important topic, especially the controversial issue of frequent overnights with nonresidential parents, is understudied. The authors analyzed data from the Fragile Families and Child Wellbeing Study, a longitudinal investigation of children born to primarily low-income, racial/ethnic minority parents that is representative of 20 U.S.

Accounting for the physical and mental health benefits of entry into marriage: a genetically informed study of selection and causation.

Married adults show better psychological adjustment and physical health than their separated/divorced or never-married counterparts. However, this apparent "marriage benefit" may be due to social selection, social causation, or both processes. Genetically informed research designs offer critical advantages for helping to disentangle selection from causation by controlling for measured and unmeasured genetic and shared environmental selection.
