Do Single‐Sex STEM Programs Have Merit? If So, for Whom, on What Measures?

Science Education, EarlyView.
ABSTRACT Single‐sex STEM programs—defined here as voluntary, gender‐segregated extracurricular or supplemental activities (e.g., summer camps, workshops, robotics clubs, internships, or citizen science initiatives)—have experienced heightened popularity and scrutiny amid efforts to increase diversity in STEM fields.

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Unraveling Interband Hot‐Electron Transfer in Hydrogenated Au@Cu2O/TiO2 Heterostructure Nanocrystals for Enhanced Hydrogen Evolution

Small, EarlyView.
Hydrogenated Au@Cu2O/TiO2 nanocrystals with oxygen‐vacancy‐engineered heterostructures enable efficient hot‐electron transfer. A Z‐scheme heterojunction forms between TiO2 and Cu2O, suppressing electron‐hole recombination and leading to a hydrogen evolution rate of 9.3 mmol g−1 h−1, with AQYs of 2.5% at 650 nm and 0.8 % at 800 nm, extending activity ...

The Interactional Pathways of Mass Killings: Toward a Novel Understanding of Rampage School Shootings

Symbolic Interaction, EarlyView.
Rampage school shootings, where students go to their own school to randomly kill classmates, teachers, friends, and strangers, are among the most drastic types of human behavior. While research increasingly points to interaction dynamics as being key for the emergence of crime and violence, scholars have not yet systematically studied interaction ...
