Objectives: Tobacco point-of-sale advertising, particularly in retailers surrounding schools, is associated with youth tobacco use and must be monitored. This study examines how the point-of-sale environment surrounding youth changed over time with regard to diverse tobacco products.
Methods: Each spring from 2015 to 2018, research staff visited the same tobacco retailers ( = 141) within a half-mile of New Jersey high schools. For cigarettes, cigars, electronic cigarettes, and smokeless tobacco, advertisement presence, volume, and share of advertising voice (SAV) were measured for both the exterior and interior of the store. Analyses examined changes over time by product, controlling for store type and poverty.
Results: Over time, exterior cigarette advertisements declined in presence (61% to 49%) and SAV (50% to 40%), whereas interior advertisements maintained stable presence, volume, and SAV. In contrast, cigar advertisements increased in presence (exterior 11% to 23%; interior 19% to 30%) and volume (exterior mean 0.2 to 0.5; interior 0.3 to 0.8). For electronic cigarettes, exterior and interior advertising presence, volume, and SAV decreased from 2015 to 2017 but increased in 2018. Smokeless tobacco advertising was infrequent and stayed consistent except in volume in the interior of stores (mean 0.2 to 0.3). When there were any differences by store type, chain convenience stores had the most exterior and interior advertising for all products.
Conclusions: The longitudinal changes observed for each product's advertising reflect national youth use rates of the corresponding products. The point-of-sale environment around schools may be influencing youth tobacco use and must be monitored and regulated.

The heat-induced natural egg yolk is a discontinuous object formed by the accumulation of yolk spheres. However, the reason why yolk spheres form individual microgels rather than continuous gels has not been elucidated. This study investigated the different gelation behaviors in the yolk sphere exterior (EYSE) and the yolk sphere interior (EYSI) by using 4D-DIA proteomics, electron microscopy, and multispectral techniques.

Copper-based catalysts demonstrate distinctive multicarbon product activity in the CO electroreduction reaction (CORR); however, their low selectivity presents significant challenges for practical applications. Herein, we have developed a multilevel porous spherical CuO structure, wherein the mesopores are enriched with catalytic active sites and effectively stabilize Cu, while the macropores facilitate the formation of a "gas-liquid-solid" three-phase interface, thereby creating a microenvironment with an increasing water concentration gradient from the interior to the exterior. Potential-driven phase engineering and protonation synergistically optimize the reaction pathway, facilitating a switch between CO and CH.

Core-shell structures demonstrate superior capability in customizing properties across multiple scales, offering valuable potential in catalysis, medicine, and performance materials. Integrating functional nanoparticles in a spatially controlled manner is particularly appealing for developing sophisticated architectures that support heterogeneous characteristics and tandem reactions. However, creating such complex structures with site-specific features remains challenging due to the dynamic microenvironment during the shell-forming process, which considerably impacts colloidal particle assembly.

2D materials feature large specific surface areas and abundant active sites, showing great potential in energy storage and conversion. However, the dense, stacked structure severely restricts its practical application. Inspired by the structure of bamboo in nature, hollow interior and porous exterior wall, hollow MXene aerogel fiber (HA-TiCT fiber) is proposed.

This study employs first-principles calculations to investigate the geometric and electronic properties of hydrogenated silicon nanotubes (SiNTs). SiNTs, particularly in their gear-like configuration, demonstrate unique semiconducting behavior; however, their relatively small intrinsic band gaps limit their applicability in fields requiring moderate band gaps. Significant changes in electronic properties are observed by hydrogenating SiNTs at various levels of adsorption-either full or partial-and different surface configurations (exterior, interior, or dual-sided).
