(Hymenoptera: Aphelinidae) is recorded here for the first time in Italy as a parasitoid of the whitefly (Hemiptera: Aleyrodidae), one of the most invasive alien pests of exotic species. originating from the Oriental region, has established a global presence. Monitoring of the whitefly and its parasitoids was conducted in the southern areas of Italy, providing crucial insights into their distribution and interactions.

To achieve the commercialization of two-dimensional (2D) semiconductors, the identification of an appropriate combination of 2D semiconductors and three-dimensional (3D) metals is crucial. Furthermore, understanding the van der Waals (vdW) interactions between these materials in thin-film semiconductor processes is essential. Optimizing these interactions requires precise control over the properties of the vdW interface through specific pre- or post-treatment methods.

Article Synopsis
- The study highlights the importance of controlling emerging structural and electronic phases in solid materials to enhance their functionality, particularly in catalytic applications.
- The research focuses on grain boundaries (GBs) within LaNiO (LNO), as they can be engineered to improve reactions for oxygen evolution.
- The findings reveal that the LNO (110)/(111) GB demonstrates superior performance in oxygen evolution due to its strong Ni-O covalency and optimal band structure, advancing our understanding of GBs in catalytic performance.
Isotope-dependent site occupation of hydrogen in epitaxial titanium hydride nanofilms.

Hydrogen, the smallest and lightest element, readily permeates a variety of materials and modulates their physical properties. Identification of the hydrogen lattice location and its amount in crystals is key to understanding and controlling the hydrogen-induced properties. Combining nuclear reaction analysis (NRA) with the ion channeling technique, we experimentally determined the locations of H and D in epitaxial nanofilms of titanium hydrides from the analysis of the two-dimensional angular mappings of NRA yields.

The "Sign-tracker/Goal-tracker" (ST/GT) is an animal model of individual differences in learning and motivational processes attributable to distinctive conditioned responses to environmental cues. While GT rats value the reward-predictive cue as a mere predictor, ST rats attribute it with incentive salience, engaging in aberrant reward-seeking behaviors that mirror those of impulse control disorders. Given its potential clinical value, the present study aimed to map such model onto humans and investigated resting state functional magnetic resonance imaging correlates of individuals categorized as more disposed to sign-tracking or goal-tracking behavior.
