Ag doped Ba strontium hexaferrite AgBaSrFe12O19 were prepared using urea precursor by auto combustion method. Samples were characterised by using different measurement techniques. X-ray diffraction (XRD) confirmed the formation of M phase with an average crystallite size of 24–45 nm. Observed tensile strain leads to t…
ABSTRACT Real‐time process metrology and control have long been considered as effective measures in direct response to operational disruptions and sustainability appeals within the glass industry. However, common challenges such as insufficient granularity, complex interdependencies, and harsh operating environments p…
ABSTRACT Cloisite Na + (Na‐MMT), a hydrated aluminium silicate belonging to the class of montmorillonite, is a widely used nanomaterial which can improve various physical properties. In this study, NR latex was mixed with a dispersion of Na‐MMT at various concentrations (1, 2, 3, 5, 10, and 15 wt.%) and co‐coagulated…
In this work, we report the first growth of single crystals of the substitution series HoFe$_{1-x}$Al$_x$O$_3$ with aluminium concentrations up to $x=0.2$ and investigate the evolution of their spontaneous spin-reorientation transition (SRT). Among rare-earth orthoferrites, HoFeO$_3$ exhibits a distinctive sequence of…
We study the nonlinear stochastic Cahn-Hilliard equation per- turbed by additive colored noise. We show almost sure existence and regularity of solutions. We introduce spatial approximation by a standard finite element method and prove error estimates of optimal order on sets of probability arbitrarily close to 1. We…
We introduce Automatic Symbolic Regression (AutoSR), a fully automated system that instantiates Research-Space Symbolic Regression by searching persistent scientific investigations rather than isolated equations. Finite, noisy data often yield numerically competitive expressions that imply very different behavior outs…
In this study, calcium oxide was synthesized from waste eggshells and subsequently converted to calcium hydroxide via two distinct methods: hydrothermal (H) and bubble (B) techniques. The influence of synthesis parameters including hydration method, type of hydration agent (pure water or ethanol‐water mixture), temper…
Объектом исследования является техническое состояние наружных кирпичных стен зданий. Для решения задачи определения их общего технического состояния предложена модель, использующая гибридный подход, объединяющий интерпретируемость нечеткой логики и обучаемость нейронных сетей.Разработана нейро-нечеткая сеть с пятью сл…
Latent-space molecular generators often leave unclear whether distance in the latent space reflects meaningful chemical similarity and which regions can be reliably decoded. A Transformer-based SMILES generator, trained from scratch, shows through Monte Carlo sampled decoding that most latent points are not “dead” but…
ABSTRACT This study evaluated whether the incorporation of sodium diclofenac‐loaded microspheres into a calcium hydroxide paste enhances antibiofilm activity while maintaining physicochemical properties and biocompatibility. Calcium hydroxide paste, calcium hydroxide combined with sodium diclofenac, and calcium hydrox…
Van der Waals heterostructures (vdW HTSs) incorporating graphene (GE) have been an active area of research, both theoretical and experimental, due to their potential to yield devices with a wide variety of applications. In this paper, first-principles calculations are employed to investigate C$_{6}$N$_{6}$/GE, hg-C$_{…
We report structural and physical investigations on the biaxial smectic-A phase exhibited by a compound consisting of asymmetric bent-core molecules. Upon cooling from the isotropic phase, the compound exhibits the following phase sequence: Isotropic (403.9 K) $\rightarrow$ biaxial Smectic-A (359.8 K) $\rightarrow$ Cr…
Accurate estimation of the NOx storage amount is essential for optimizing rich-spike control and improving fuel consumption in NOx storage-reduction (NSR) catalysts. In practical applications, however, the estimation accuracy is often degraded by uncertainties in the state estimation model’s input variables. To addres…
ABSTRACT Sago bagasse, an abundant lignocellulosic by‐product with potential as a renewable source of nanocrystalline cellulose (NCC). This study aims to evaluate the effect of hydrolysis time (60 and 75 min) on the physicochemical properties of NCC prepared from Bogor‐variety sago waste, followed by ball milling as a…
Large language models (LLMs) are increasingly proposed as assistants for chemical process modeling, yet existing benchmarks grade them with LLM judges, which are lenient and not reproducible. We introduce PROBE, an executable benchmark that scores LLM-generated first-principles process models objectively, and report a…
Template-based computer-aided synthesis planning offers interpretability and explicit control over reaction application, but its behavior is strongly influenced by the training data and template-ranking policy used during search. This may limit chemists’ ability to apply a rare or project-specific transformation poorl…
Retrosynthesis of complex molecules requires many chemically plausible transformations to be integrated into a coherent synthetic route. Although computational methods have improved reaction prediction and route identification, systematically decomposing complex molecules and coordinating multiple retrosynthetic steps…
Two-dimensional (2D) magnetic materials provide a versatile platform for spintronic and quantum applications, but achieving stable ferromagnetism over a broad temperature range remains a major challenge. Here, we report the discovery of 2D ZrCl nanoplates with robust ferromagnetism persisting up to 400 K, demonstratin…
Scintillators are indispensable for the detection of X-rays, $γ$-rays, and energetic particles in applications ranging from medical imaging and security screening to high-energy physics. A major limitation of conventional scintillators is the inefficient extraction of scintillation photons caused by isotropic emission…
Abstract Overcoming the enthalpy–entropy compensation effect remains a formidable challenge in chemical upcycling of polyesters. Empirical catalyst designs typically maximize Lewis acidity, lowering activation enthalpy (Δ H ‡) for ester activation but triggering an entropic penalty (Δ S ‡) that retards kinetics. Here,…
