Child care providers, including family child care (FCC) providers, are viewed as trusted sources of information for the parents and families they serve, and their vaccine behavior has been shown to be associated with parent beliefs and behaviors. This study sought to describe the COVID-19 vaccine behaviors and attitudes among FCC providers in Delaware. An online survey was distributed to all licensed FCC providers ( = 541) in September 2021. Survey items were drawn from validated instruments and assessed vaccination status, attitudes, and confidence in their ability to discuss COVID-19 vaccines with families. In total, 168 responses were recorded (31% response rate); 69.8% of respondents were fully vaccinated against COVID-19. The majority indicated that they would require (11.4%) or recommend (42.1%) the vaccine for children in their care, once approved by the FDA. Providers reported high levels of confidence in their ability to discuss both the benefits and risks of COVID-19 vaccines. FCC providers should be considered key messengers for the families they serve and may be helpful liaisons with state and local vaccination efforts. Input from FCC providers could be used to develop vaccine messaging and materials that are clear, consistent, and culturally responsive to the families of the children in their care.

(FeCoNi)A high-entropy alloy (HEA) is a new material with a strength similar to that of commercial Q235 structural steel, and its elongation is nearly three times greater than that of Q235 steel. Studying the welding process of the (FeCoNi)Al HEA and Q235 steel is expected to further expand the application range of commercial Q235 structural steel and provide a foundation for the engineering application of the (FeCoNi)Al HEA. This study focuses on the dissimilar welded components of (FeCoNi)Al HEA and Q235 steel and analyzes the forming quality, microstructure, and mechanical properties of dissimilar welded samples under different currents.

The recent synthesis of goldene, a 2D atomic monolayer of gold, has opened new avenues in exploring novel materials. However, the question of when multilayer goldene transitions into bulk gold remains unresolved. This study used density functional theory calculations to address this fundamental question.

Materials usually fracture before reaching their ideal strength limits. Meanwhile, materials with high strength generally have poor ductility, and vice versa. For example, gold with the conventional face-centered cubic (FCC) phase is highly ductile while the yield strength (~10MPa) is significantly lower than its ideal theoretical limit.

The ability to finely tune the nuclearity of active metal sites is critical for designing highly selective catalysts, especially for hydrogenation processes. In this work, we developed a novel PdCu catalyst with an ordered body-centered cubic (BCC) structure, enabling precise control over Pd nuclearity to optimize selectivity. Using a facile polyol synthesis method, we modulated the Pd coordination environment, reducing the Pd-Pd coordination number from 3 (disordered face-centered cubic, FCC) to 0 (ordered BCC), thereby achieving full isolation of Pd by the surrounding Cu atoms.
