Multiobjective optimization of foamed concrete for sustainable construction using statistical and artificial intelligence approaches

Abstract Foamed concrete is lightweight and insulating, but its mix design is a headache. Strength, durability, and carbon footprint all fight each other. This review looks at how researchers have tried to optimize these trade-offs using methods like RSM, Taguchi, ANN, and geneti...

Technostress and trust in AI mediate the association between AI adoption and employee well-being

Artificial intelligence (AI) technology adoption alters organizational workplaces, automating tasks and processes, augmenting decision-making capabilities, and changing employees’ perceptions of work. While past research has demonstrated positive effects of AI on productivity and...

Cost-effective green synthesis and characterisation of arsenotungstate nanoparticles: enhanced sorption of Pb²+, antioxidant and photocatalytic properties with non-isothermal decomposition kinetics

Environmental context This work presents a synthesis of arsenotungstate nanoparticles and emphasises the significance of removing toxic pollutants in wastewater, as well as its applications for health and environmental benefits. Our study highlights the ecological and human healt...

Low‐Threshold Red Lasing in Diketopyrrolopyrrole‐Based Organic Semiconductor Films

ABSTRACT Achieving low‐lasing threshold organic semiconductor lasers (OSLs) in the red to deep‐red region remains challenging due to the intrinsic trade‐off between long‐wavelength emission and high optical gain. Extended π‐conjugation required for red‐shifted emission typically...

First-Principles Investigation into Structural and Optoelectronic Properties of Mixed Halide Perovskites CsPbBr3– y X y (X = I, Cl, F; y = 0, 1, 2, 3) Using GGA, mBJ, mBJ + SOC, and HSE Functionals

Abstract This study presents a comprehensive density functional theory investigation into the structural, electronic, and optical properties of inorganic halide perovskites with the general formula CsPbBr3–yXy (where X = I, Cl, F; and y = 0, 1, 2, 3). Using the Vienna Ab initio S...

Enhanced Room-TemperaturePhosphorescence from CarbonDots Embedded in a Robust SiO2 Matrix

Abstract Carbon dots (CDs) represent a rapidly advancing class of fluorescent nanomaterials. Due to the dominant nonradiative decay channels of the triplet excited state of CDs, these materials generally exhibit no observable phosphorescence (PH) or delayed fluorescence. Here, we...
