Objective Despite the increasing scholarly attention toward self‐stigma among Asian breast cancer survivors, research is limited about the underlying psychological mechanisms by which self‐stigma may influence quality of life for this population. The present study investigated how self‐stigma is associated with quality of life among Chinese American breast cancer survivors by examining the serial mediating effects of concerns about breast cancer, self‐efficacy for coping with cancer, and depressive symptoms. Methods Chinese American breast cancer survivors (n = 112) completed a questionnaire packet assessing self‐stigma related to breast cancer, concerns about breast cancer, self‐efficacy for coping with cancer, depressive symptoms, and quality of life. Path analysis was conducted to test the hypothesized serial multiple mediation model. Results The hypothesized model was supported: self‐stigma was negatively associated with quality of life through concerns about breast cancer, self‐efficacy, and depressive symptoms. After the mediators were controlled for, the direct effect of self‐stigma on quality of life was no longer significant. Conclusions Our findings suggest that concerns about breast cancer, self‐efficacy for coping, and depressive symptoms are important pathways through which self‐stigma may influence quality of life among Chinese American breast cancer survivors. Healthcare practitioners should be aware of survivors' self‐stigma and make efforts to alleviate survivors' excessive cancer concerns, facilitate their self‐efficacy, and offer emotional support to improve quality of life for this population.

Designing unique nanostructures and components for catalysts can promote the deep catalytic degradation of volatile organic compounds into CO 2 . Herein, a pyrolysis strategy for MOFbased oxides (Mn 3 [Co(CN) 6 ] 2 •nH 2 O) was employed to successfully synthesize oxygen vacancy-enriched Mn−Co spinel oxides with hollow nanocube structures (denoted as MOF-CMO/400). Compared with CoMn 2 O 4 nanoparticles prepared by the traditional precipitation method, MOF-CMO/400 presented a T 90 of 209 °C for toluene catalytic oxidation, which was 38 °C lower than that of CoMn 2 O 4 nanoparticles (247 °C). Especially in a high-temperature region, MOF-CMO/400 nanocubes possessed a narrower temperature range to achieve 100% toluene conversion than CoMn 2 O 4 nanoparticles. The excellent catalytic activity of MOF-CMO/400 is mainly attributed to the three-dimensional hollow structure, more oxygen vacancy defects, longer Mn−O bonds, and abundant active oxygen species. Furthermore, MOF-CMO/400 nanocubes displayed good humidity resistance (above 5−10 vol % H 2 O). Therefore, the nanocatalyst with a distinctive structure and defects has great potential in industrial application for deep toluene oxidation.

Mn-based metal oxides have shown promising performance in catalytic oxidation of toluene since the mixed valences of Mn3+ and Mn4+ on the surface. Herein, a series of Co-Mn catalysts were...

Ti doping can improve the photoelectrochemical water splitting performance of hematite. However, the effect of doping on regulating small polaron hopping in the bulk and charge transfer properties on the solid–liquid interface is not fully understood. In this paper, we investigate the effects of titanium doping on hematite by decoupling a hematite homojunction structure into bulk and surface layers. We found that 3% Ti doping remarkably reduces the small polaron hopping (SPH) barrier, which leads to the high bulk charge transport, and 5% Ti doping significantly passivates the recombination of the surface states (r-SS) of hematite and promotes the conversion of the surface holes to long-lived reaction intermediates (i-SS) on the solid–liquid interface, which leads to the high surface charge transfer. Based on the above results, we report first an unconventional Ti-doped hematite homojunction design that is established with 3% Ti-doped hematite as the underlayer and 5% Ti-doped hematite as the surface layer. The homojunction exhibits a significantly enhanced photocurrent density (1.27 mA cm–2) compared to that of the typical type-II hematite structure at 1.5 VRHE. This work has well demonstrated a new homojunction design strategy for enhancing the photoelectrochemical water splitting.
