Facile fabrication of transparent and stretchable cellulose ionic gel paper for sustainable use in multifunctional sensors and optoelectronic devices.

Although transparent paper derived from cellulose has been successfully demonstrated as an inexpensive, renewable and biodegradable substrate used for flexible electronics, the inherently stiff characteristic and intrinsic poor conductivity of the cellulose paper inevitably hinders its application in stretchable electronic devices. Herein, we report a new avenue for construction of highly stretchable, transparent, and ionic conductive cellulose gel paper via glycerol inducing plasticizing and CaCl initiating chelating, a facile casting and drying strategy. The renewable carboxymethyl cellulose is employed for its intrinsically abundant carboxyl groups for crosslinking with Ca via ionic coordination bonds, benefiting the improvement of various performances.

The development of multicolor carbon dots and their applications in the field of anti-counterfeiting.

The diversity of photoluminescence emission of multicolor carbon dots (mCDs) greatly broadens their application field. Counterfeiting is a problem that has serious consequences for individuals and society. The fluorescent ink based on mCDs has been developed due to their low toxicity and good resistance to photobleaching in the field of anti-counterfeiting.

Advances in total antioxidant capacity detection based on nanozyme.

Nanozymes, a class of nanomaterials mimicking natural enzymatic functions, have gained significant attention due to their exceptional biocatalytic properties and wide-ranging applications in biosensing. The total antioxidant capacity (TAC) can serve as a crucial parameter for assessing food quality, guiding dietary choices, and monitoring health conditions. In recent years, various nanomaterials with peroxidase (POD)-like and oxidase (OXD)-like activity have been widely used for TAC determination.

Chlorination treatment actuated structural reconstitution and aggravated toxicity of molybdenum disulfide nanosheets to freshwater algae.

The extensive application of molybdenum disulfide (MoS) nanosheets in various fields involving in water treatment inevitably results in their release into wastewater treatment plants, and eventually into aquatic environments following disinfection. However, little is known about the transformations and toxicity evolution of MoS during chlorination. This study discovered that MoS is unstable to NaClO exposure, and more soluble ions are released under UV/NaClO co-treatment due to the generation of •OH and chlorine radicals.

Stress hyperglycemia ratio and 30-day mortality among critically ill patients with acute heart failure: analysis of the MIMIC-IV database.

Background: The association between the stress hyperglycemia ratio (SHR) and short-term prognosis of acute heart failure (AHF), particularly among those admitted to the intensive care unit (ICU), has not been elucidated. This study aimed to investigate the association between the SHR and adverse outcomes among critically ill patients with AHF and provide a reference for glycemic management range in these patients.

Methods: We extracted the clinical data of patients from the MIMIC-IV (v3.
