Understanding the Role of Irisin in Longevity and Aging: A Narrative Review.

Irisin is a protein resulting from a proteolytic cleavage of fibronectin type III domain-containing protein 5 (FND5). The ability of irisin to modulate adipocyte and control glucose metabolism in human metabolic diseases gave rise to the hypothesis that irisin could have a pivotal role in aging-related diseases. Although in animal models, increased levels of irisin have been positively associated with better health outcomes, in humans, its role remains controversial.

Computational modeling of the Nb -CO chemisorption process.

Context: The transition metal niobium (Nb) has attracted considerable attention from the scientific community due to its intriguing electronic properties and applications in catalysts suitable for chemical reactions. Thus, this work investigates the adsorption of the atmospheric polluting gas carbon monoxide (CO) by the niobium cluster (Nb ), to describe the reactive nature of Nb . This entire study was carried out by applying the Coupled-Cluster method and Density Functional Theory (through the HSE06 functional) and the def2-QZVP plus Def2-TZVP/C auxiliary basis set functions.

Unveiling the Role of Electronic, Vibrational, and Optical Features of the 1T' WSe Monolayer.

Understanding the optoelectronic profile and chemical stability of transition-metal dichalcogenides (TMDs) is crucial for advancing two-dimensional (2D) material applications, particularly in electronics, optoelectronics, and energy devices. Here, we investigate the structural, electronic, optical, and excitonic properties of the 1T' WSe monolayer. Phonon dispersion analysis confirmed the thermodynamic stability of this system.
