Nondestructive halide exchange via S2-like mechanism for efficient blue perovskite light-emitting diodes.
Nat Commun
December 2024
Macao Institute of Materials Science and Engineering (MIMSE), Faculty of Innovation Engineering, Macau University of Science and Technology, Taipa, Macao, China.
Article Synopsis
- Blue perovskite light-emitting diodes (PeLEDs) face challenges due to difficult production of high-quality mixed-halide perovskites with wide optical bandgaps, leading to high defect density.
- A new strategy for nondestructive in-situ halide exchange helps create high-quality blue perovskites with low trap density by using long alkyl chain chloride in chloroform post-treatment.
- This method improves efficiency in PeLEDs across the blue spectrum, achieving external quantum efficiencies of 23.6% (sky-blue), 20.9% (pure-blue), and 15.0% (deep-blue) emissions.
Incretin-Based Therapies and Lifestyle Interventions: The Evolving Role of Registered Dietitian Nutritionists in Obesity Care.
J Acad Nutr Diet
November 2024
Academy of Nutrition and Dietetics, Chicago, Illinois. Electronic address:
The emergence of incretin-based therapies, specifically glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and glucose-dependent insulinotropic polypeptide (GIP), as a new class of obesity medications, is dramatically changing obesity care. Use of these medications, known categorically as anti-obesity medications, as part of comprehensive obesity management is associated with significantly greater weight loss and health benefits than found with earlier-generation obesity medications. The outcomes reported from medication trials were often achieved in conjunction with lifestyle counseling sessions by a registered dietitian nutritionist (RDN) or other qualified health care professional.

Torque measurement is a key task in several mechanical and structural engineering applications. Most commercial torquemeters require the shaft to be interrupted to place the sensors between the two portions of the shaft where a torque has to be measured. Contactless torquemeters based on the inverse magnetostrictive effect represent an effective alternative to conventional ones.

Follicular lymphoma (FL) is the second most common type of lymphoma (20% of all non-Hodgkin lymphomas), derived from germinal centre (GC) B cells, and is characterised by its significant clinical, prognostic and biological heterogeneity, leading to complexity in management. Despite significant biological investigation and indisputable clinical progress since the advent of the immunotherapy era more than 20 years ago, much remains to be done to understand and cure this lymphoma. Today, FL is metaphorically a giant puzzle on the table with patches of sky, landscape and foliage clearly appearing.

Understanding the historical perception and value of teacher personalities reveals key educational priorities and societal expectations. This study analyzes the evolution of teachers' ascribed Big Five personality traits from 1800 to 2019, drawing on millions of English-language books. Word frequency analysis reveals that conscientiousness is the most frequently discussed trait, followed by agreeableness, openness, extraversion, and neuroticism.
