Dietary Intakes and Eating Behavior between Metabolically Healthy and Unhealthy Obesity Phenotypes in Asian Children and Adolescents.

Diet plays a critical role in the development of obesity and obesity-related morbidities. Our study aimed to evaluate the dietary food groups, nutrient intakes and eating behaviors of metabolically healthy and unhealthy obesity phenotypes in an Asian cohort of children and adolescents. Participants ( = 52) were asked to record their diet using a 3-day food diary and intakes were analyzed using a nutrient software.

Suppressing ion migration of CsPbBrInanocrystals by Nickel doping and the application in high-efficiency WLEDs.

All inorganic perovskite nanocrystals CsPbX(X = Cl, Br, I) are the great potential candidates for the application of high-performance light emitting diodes (LED) due to their high Photoluminescence Quantum Yield (PLQY), high defect tolerance, narrow full-width half-maximum and tunable wavelength of 410-700 nm. However, the application of red-emitting (630-650 nm) CsPbBrInanocrystals are perplexed by phase segregation due to the composition of mixed halides and the difference in halide ion mobility. Herein, we provide an effective strategy to suppressing the migration of Br/I ions through Nidoping via a facile Hot-Injection method and the PLQY was improved as well.

Highly efficient and blue-emitting CsPbBr quantum dots synthesized by two-step supersaturated recrystallization.

Highly efficient and blue-emitting CsPbBr quantum dots were successfully synthesized by two-step supersaturated recrystallization under ambient condition. This method could control the particle size within 2.8 nm, thus resulting in strong quantum confinement effect of the products.
