Quantum repeaters are essential for overcoming the exponential photon loss that limits entanglement generation over long distances in quantum networks. An absorption-emission-based quantum repeater exploits the fundamental light-matter interactions of a diamond nitrogen-vacancy (NV) center---photon absorption and phot…
Phase equilibrium problems are central to chemical engineering, underpinning tasks ranging from separation process design to the development of thermodynamic models. A particularly challenging computational task is the generation of phase envelopes: rigorously fitting thermodynamic models to real world data with well…
Anderson localization and the mobility edge (ME) have been extensively studied in isolated aperiodic systems. Conventional theory suggests that dephasing and decoherence should disrupt localization and facilitate transport. In this work, we investigate localization behaviors in a dimerized off-diagonal Aubry-Andre-Har…
Green synthesis has emerged as a sustainable alternative to conventional physical and chemical routes for the preparation of metal oxide nanoparticles, offering advantages such as environmental compatibility and reduced use of hazardous reagents. In the present study, cobalt oxide nanoparticles were synthesized using…
In this communication, we present the influence of Praseodymium (Pr) doping on structural and elastic properties of nickel ferrite nanoparticles investigated through X-ray diffraction and Fourier transform infrared studies. The samples of NiFe2-xPrxO4 (x = 0.0, 0.025, 0.050, 0.075, 0.1) nanoparticles were prepared usi…
Layered transition metal dichalcogenides are an important platform for two-dimensional materials, where the inevitable intrinsic defects provide new degrees of freedom for tuning their physical properties. Based on first-principles calculations, this work systematically investigates the formation energies, charge stat…
Large language models (LLMs) are increasingly used for scientific hypothesis generation. However, evaluating generated hypotheses remains a challenge for trustworthy AI-enabled scientific workflows. Existing approaches often use LLMs as judges or rely on semantic similarity, which can favor familiar ideas over novel o…
Despite of the extensive research on fiber reinforced and particulate filled polymers, the combined effect of bamboo dust in glass fiber and aluminum wire mesh reinforced multi-fiber hybrid composites has not been studied yet. In view this, the present introduces a novel multi-fiber polymer composite using micro-sized…
The present study investigates the influence of growth time on the physical properties of ZnO thin films grown by the hydrothermal method. Film fabrication is carried out via a two-step process involving the deposition of ZnO seed layers on glass substrates by spin coating, followed by hydrothermal growth. Post-deposi…
O tratamento térmico é amplamente utilizado na indústria automotiva para garantir propriedades mecânicas adequadas aos componentes submetidos a elevadas solicitações de carga e desgaste. Este estudo teve como objetivo avaliar a influência do tempo e da temperatura de revenimento no aço SAE 4122, visando reduzir o temp…
We develop an analytical theory for the dense packing of hard spheres in cylinders. Physically, our theory consists of a finite cylindrical masking of a close-packed three-dimensional solid and covers the entire range of cylinder aspect ratios, thus going beyond efforts that are focused on very tall cylinders in a nar…
ABSTRACT Anodic coating (~10–20 µm) was developed on AA2014 (Al‐Cu‐Mg) and AA6351(Al‐Mg‐Si) aluminum alloys for spacecraft applications (brackets, modules and metallic decks). The anodization was carried out in an electrolyte bath of sulfuric acid and a mixture of sulfuric acid and oxalic acid, for AA6351 and AA2014 a…
Light can induce both photothermal and nonthermal catalytic activity in plasmonic nanoparticles, but the extent, timescale, and efficacy of these two mechanisms remain unresolved. Here we introduce pump-pump photocatalysis, an adaptation of ultrafast excitation correlation spectroscopy in which incident laser pulses a…
Abstract Minimizing power consumption and improving long-term stability of bioelectronic devices are crucial for ensuring prolonged operation and reducing the risk of tissue damage. Organic electrochemical transistors (OECTs) have gained widespread attention in biosensing applications due to their high transconductanc…
We develop a thermomechanical framework for viable Horndeski scalar hair with spacelike scalar-field gradients. Adapting the $(1{+}1{+}2)$ formalism to the scalar configuration, we apply the effective imperfect-fluid decomposition to the model and derive general results governing its thermomechanical properties. Speci…
Background: The widespread use of ionizing radiation in medical and industrial applications has increased the demand for effective and lead-free radiation shielding materials. Rare earth doped glass systems have attracted attention due to their optical transparency and favorable attenuation properties. Objectives: Thi…
The structure of the material plays an important role in determining the electrical, magnetic, and electromagnetic properties of the material. Aluminium-doped M-type barium hexaferrite, BaFe11.5Al0.5O19 has been prepared using the sol-gel auto-combustion method and systematically studied to understand the structural a…
High-density, semiconducting aligned carbon nanotube arrays (A-CNTs) are essential for next-generation electronics. Dimension-limited self-alignment (DLSA) is a leading route to wafer-scale A-CNT fabrication, yet the instabilities that limit array quality remain poorly understood, hampering targeted process optimizati…
The emergence of clean energy around the globe has propelled the development of electric vehicles (EVs), which are considered to be environmentally sustainable means of transport compared to those run on fossil fuels. However, the utilization of rare earth elements (REE) containing permanent magnets in the EV traction…
Achieving high quantum yields in neat films of extended heteroacenes remains challenging because their large aromatic surfaces promote aggregation-caused quenching and non-radiative decay, while often limiting solubility and processability. Here we introduce proximal steric shielding to control solid-state emission in…
