Romantic passion represents one of the most fragile and elusive elements of relationship quality but one that is increasingly valued and tied to relationship and individual well-being. Selleck ALK inhibitor We provide the first examination of whether experiencing personal self-expansion-positive self-change and personal growth without a romantic partner-is a critical predictor of passion. Previous research has almost exclusively examined the consequences of couples' sharing novel experiences (i.e., relational self-expansion) on romantic relationships. Instead, the consequences of personal self-expansion for romantic relationships remain largely unexamined even though most positive self-growth may occur without a romantic partner (e.g., at work). We investigated the consequences of personal self-expansion for passion in three studies including two 21-day experience sampling studies of community couples and a study in a context likely to elicit heightened personal self-expansion during job relocation. Within-person increases in daily personal self-expansion were associated with greater passion through greater positive emotions (Studies 1 and 2). In contrast, high between-person levels of personal self-expansion were associated with lower passion through lower levels of intimacy, suggesting that individuals may drift apart from their partners with more chronic personal self-expansion (Studies 1, 2, and 3). That is, consistently growing outside of the relationship in ways that are not shared with a romantic partner may reduce feelings of closeness and connection, and ultimately passion. Results also suggest that chronic personal self-expansion may be a double-edged sword for individual well-being, simultaneously associated with lower passion, but greater fulfillment of competence needs. Results controlled for relational self-expansion and time together.

Seven studies (N = 4,213) document the sacrosanct nature of rituals Because group rituals symbolize sacred group values, even minor alterations to them provoke moral outrage and punishment. In Pilot Studies A and B, fraternity members who failed to complete initiation activities that were more ritualistic elicited relatively greater moral outrage and hazing from their fraternity brothers. Study 1 uses secular holiday rituals to explore the dimensions of ritual alteration-both physical and psychological-that elicit moral outrage. Study 2 suggests that altering a ritual elicits outrage even beyond the extent to which the ritual alteration is seen as violating descriptive and injunctive norms. In Study 3, group members who viewed male circumcision as more ritualistic (i.e., Jewish vs. Muslim participants) expressed greater moral outrage in response to a proposal to alter circumcision to make it safer. Study 4 uses the Pledge of Allegiance ritual to explore how the intentions of the person altering the ritual influence observers' moral outrage and punishment. Finally, in Study 5, even minor alterations elicited comparable levels of moral outrage to major alterations of the Jewish Passover ritual. Across both religious and secular rituals, the more ingroup members believed that rituals symbolize sacred group values, the more they protected their rituals-by punishing those who violated them.

The reaction is accomplished by irradiation with visible light in the absence of a photosensitizer and is suggested to proceed by excitation of a ternary electron donor-acceptor complex between the NHPI ester, Hantzsch ester, and a Ln(OTf)3.Monoelemental two-dimensional materials (borophene, silicene, etc.) are exciting candidates for electrodes in lithium-ion batteries because of their ultralight molar mass. However, these materials' lithium-ion binding mechanism can be complex as the inherited polymorphism may induce phase changes during the charge-discharge cycles. Here, we combine genetic-algorithm-based bottom-up and stochastic top-down structure searching techniques to conduct thermodynamic scrutiny of the lithiated compounds of 2D allotropes of four elements B, Al, Si, and P. Our first-principles-based high-throughput computations unveil polymorphism-driven lithium-ion binding process and other nonidealities (e.g., bond cleavage, adsorbent phase change, and electroplating), which lacks mention in earlier works. While monolayer B (2479 mAh/g), Al (993 mAh/g), and Si (954 mAh/g) have been demonstrated here as excellent candidates for Li-ion storage, P falls short of the expectation. Our well-designed computational framework, which always searches for lithiated structures at global minima, provides convincing thermodynamical insights and realistic reversible specific-capacity values. This will expectedly open up future experimental efforts to design monoelemental two-dimensional material-based anodes with specific polymorphic structures.The efficient nondestructive assessment of quality and homogeneity for two-dimensional (2D) MoS2 is critically important to advance their practical applications. Here, we presented a rapid and large-area assessment method for visually evaluating the quality and uniformity of chemical vapor deposition (CVD)-grown MoS2 monolayers simply with conventional optical microscopes. This was achieved through one-pot adsorbing abundant sulfur particles selectively onto as-grown poorer-quality MoS2 monolayers in a CVD system without any additional treatment. We further revealed that this favorable adsorption of sulfur particles on MoS2 originated from their intrinsic higher-density sulfur vacancies. Based on unadsorbed MoS2 monolayers, superior performance field effect transistors with a mobility of ∼49 cm2 V-1 s-1 were constructed. Importantly, the assessment approach was noninvasive due to the all-vapor-phase and moderate adsorption-desorption process. Our work offers a new route for the performance and yield optimization of devices by quality assessment of 2D semiconductors prior to device fabrication.
