This study documents the formation of optically anomalous biaxial apatite resulting from partial fluid-mediated metasomatic alteration of pegmatitic apatite containing a britholite component. The optical anomaly was identified using a refractometer. SEM and EDX data constrain alteration conditions to interaction with…
Superhydrophobic fabrics play a key role in sustainable industrial applications, including oil/water separation and self-cleaning materials. This study addresses the challenge of enhancing hydrophobicity while preserving fabric functionality by modifying its surface via dip-coating with poly(dimethylsiloxane) (PDMS) a…
This research focused on the mechanical properties of polyester composites reinforced with tamarind seed filler and Kusha mat. Four distinct composite samples were fabricated utilizing the compression molding technique, incorporating single and double-layer Kusha mats, while considering the inclusion or exclusion of t…
In this study, we used flexible and inexpensive diatomite/AgNPs strips and Layer-by-Layer (LbL) assembly to develop sandwich assays for the detection of cancer biomarkers of interest via Surface-enhanced Raman scattering (SERS). The modified SERS active strips were used to capture antigens of interest, incubate Raman…
The integration of machine learning (ML) into materials science offers a transformative pathway toward fully autonomous synthesis workflows. For precise thin-film deposition techniques like molecular beam epitaxy (MBE), this automation is critical to overcome the time-consuming, manual navigation of high-dimensional t…
Estimation of eddy-current losses in conducting non-laminated components of electrical devices requires expensive three-dimensional simulations. Various approximations are therefore used in practice to reduce the computational cost in the early design phase. We review some approaches and discuss their modelling assump…
The discovery of pressure-induced high temperature superconductivity in the bilayer nickelate La$_{3}$Ni$_{2}$O$_{7}$ has raised the question of how its spin-density-wave (SDW) state evolves toward the superconducting regime. Here, we report a systematic electronic Raman study of La$_{3}$Ni$_{2}$O$_{7}$ single crystal…
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…
