The urgent demand for efficient CO reduction technologies has driven enormous studies into the enhancement of advanced catalysts. Here, we investigate the electronic properties and CO adsorption properties of CuAg bimetallic clusters, particularly CuAg, CuAg, CuAg, and CuAg, using generalized gradient approximation (GGA)/density functional theory (DFT). Our results show that the atomic arrangement within these clusters drastically affects their stability, charge transfer, and catalytic performance.

Psoriasis is a common chronic inflammatory skin disorder that primarily affects the skin, nails, and joints. Beyond its cutaneous manifestations, psoriasis is associated with several systemic comorbidities. Various factors can trigger or exacerbate psoriasis, including stress, infections, medications, and vaccinations.

Here, we demonstrate that molecular-scale junctions that satisfy the conditions of these effects can manifest Seebeck coefficients whose sign fluctuates depending on the orientation of the molecule within the asymmetric junction in a complete theoretical investigation. Three anthracene-based compounds are investigated in three different scenarios, one of which displays a bithermoelectric behavior due to the presence of strong anchor groups, including and .

This research applies the density functional theory (DFT) coupled with the Hartree-Fock theory to meticulously examine the structural and electronic structures of Rh clusters on TiO (110) interfaces. Considering the photocatalytic capabilities of TiO and its inherent limitations in harnessing visible light, the potential for metals such as Rh clusters to act as co-catalysts is assessed.

In response to the vital requirement for renewable energy alternatives, this research delves into the complex interactions between ruthenium (Ru) clusters and rutile titanium dioxide (TiO) (110) interfaces, with the aim of enhancing photocatalytic water splitting processes to produce environmentally friendly hydrogen. As the world shifts away from traditional fossil fuels, this study utilizes the density functional theory (DFT) and the HSE06 hybrid functional to thoroughly assess the geometric and electronic properties of Ru clusters on rutile TiO (110) surfaces. Given TiO's renown role as a photocatalyst and its limitations in visible light absorption, this research investigates the potential of metals like Ru to serve as additional catalysts.

Addressing the urgent need for sustainable energy sources, this study investigates the intricate relationship between rhodium (Rh) nanoclusters and TiO rutile (110) surfaces, aiming to advance photocatalytic water splitting for green hydrogen production. Motivated by the imperative to transition from conventional fossil fuels, this study employs density functional theory (DFT) with DFT-D3 and HSE06 hybrid functionals to analyse the geometrical stabilities and electronic structures of Rh nanoclusters on TiO rutile (110). TiO, a prominent photocatalyst, faces challenges such as limited visible light absorption, leading researchers to explore noble metals like Rh as cocatalysts.

DRESS is an uncommon reaction; however, it is more prevalent than Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) and is left undiagnosed due to its atypical clinical presentation. So far, no standard criteria or investigational tool assists in early and accurate diagnosis.
