N-Doped Carbon Nanodots as Temperature Sensors and Fluorescent Probes for the Detection of Tinidazole in Milk.

In this study, nitrogen-doped carbon nanodots (N-CDs) with temperature and fluorescence sensing were prepared via hydrothermal method using L-lysine and ethylenediamine as precursors. The synthesized N-CDs exhibited spherical morphology with sizes ranging from 2.8 to 5.

Ultraelastic Lead Halide Perovskite Films via Direct Laser Patterning.

The precise patterning of elastic semiconductors holds encouraging prospects for unlocking functionalities and broadening the scope of optoelectronic applications. Here, perovskite films with notable elasticity capable of stretching over 250% are successfully fabricated by using a continuous-wave (CW) laser-patterning technique. Under CW laser irradiation, perovskite nanoparticles (NPs) undergo meticulous crystallization within the thermoplastic polyurethane (TPU) matrix, which yields the capability of an unparalleled stretch behavior.

Optimizing Yeast Homologous Recombination for Splicing Large Coronavirus Genome Fragments.

Reverse genetics is a useful tool for studying viruses and developing vaccines for coronaviruses. However, constructing and manipulating the coronavirus genome in can be time-consuming and challenging due to its large size and instability. Homologous recombination, a genetic manipulation mechanism found in organisms, is essential for DNA repair, gene recombination, and genetic engineering.

The Astragalus Membranaceus Herb Attenuates Leukemia by Inhibiting the FLI1 Oncogene and Enhancing Anti-Tumor Immunity.

Astragalus membranaceus (AM) herb is a component of traditional Chinese medicine used to treat various cancers. Herein, we demonstrate a strong anti-leukemic effect of AM injected (Ai) into the mouse model of erythroleukemia induced by Friend virus. Chemical analysis combined with mass spectrometry of AM/Ai identified the compounds Betulinic acid, Kaempferol, Hederagenin, and formononetin, all major mediators of leukemia inhibition in culture and in vivo.

A Study on the Mechanisms Influencing Older Adults' Willingness to Use Digital Displays in Museums from a Cognitive Age Perspective.

As older adults age, changes in their physiological, psychological, and cognitive functions often lead to inherent anxiety and fear regarding the use of digital technologies. Cognitive age, reflecting an older adult's mental perception of their chronological age, is a crucial moderating factor in shaping their willingness and behavior towards technology adoption. However, the mechanisms through which cognitive age impacts the behavior of older adults within the realm of digital technology utilization remain unclear.
