The effects of ostracism on preschoolers' over-imitation behaviors.

Over-imitation represents an early developing behavior implicated in the emergence of learning, affective, and social competences. Adult over-imitation is heavily affected by contextual variables such as social ostracism, the experience of being ignored by others in a social context, an experience that threatens several psychological needs, inducing the urge to reaffiliate with a social group to restore the original state of well-being. Yet, the impact of social ostracism on over-imitation in children remains unclear.

Experimental and computational aspects of molecular frustrated Lewis pairs for CO hydrogenation: en route for heterogeneous systems?

Catalysis plays a crucial role in advancing sustainability. The unique reactivity of frustrated Lewis pairs (FLPs) is driving an ever-growing interest in the transition metal-free transformation of small molecules like CO into valuable products. In this area, there is a recent growing incentive to heterogenize molecular FLPs into porous solids, merging the benefits of homogeneous and heterogeneous catalysis - high activity, selectivity, and recyclability.

Infants' psychophysiological responses to eye contact with a human and with a humanoid robot.

Eye contact with a human and with a humanoid robot elicits attention- and affect-related psychophysiological responses. However, these responses have mostly been studied in adults, leaving their developmental origin poorly understood. In this study, 114 infants (6-8 months old) viewed direct and averted gaze directions of a live human and an embodied humanoid robot while their heart rate deceleration (attention orienting), skin conductance (affective arousal), and facial muscle activity (affective valence) were measured.

An anthropocene-framed transdisciplinary dialog at the chemistry-energy nexus.

At the energy-chemistry nexus, key molecules include carbon dioxide (CO), hydrogen (H), methane (CH), and ammonia (NH). The position of these four molecules and that of the more general family of synthetic macromolecular polymer blends (found in plastics) were cross-analyzed with the planetary boundary framework, and as part of five scientific policy roadmaps for the energy transition. According to the scenarios considered, the use of some of these molecular substances will be drastically modified in the coming years.
