In recent years, CO2 conversion reactions such as CO2 reforming of CH4 and CO2 methanation have devoted significant attention on account of their advantages in utilizing greenhouse gases (CO2 and CH4). The development of an excellent catalyst with great properties is a crucial strategy in the catalytic reaction, as it could enhance the efficiency of reaction. Additionally, the tunable characteristics of support materials may influence the distribution of active metal sites, strength of metal-supporting interactions, and amount of oxygen vacancies. To improve metal dispersion on a support, the production of support materials with fibrous morphology and dendrimeric structures is becoming an exciting approach. This short review highlighted recent developments in the preparation of fibrous catalysts and their relation with the physical and chemical properties of catalyst. This article also discussed the governing factor of fibrous morphology in CO2 conversions. Owing to the fascinating physicochemical properties of fibrous catalyst, further research is needed to explore its potential in various applications. © 2021

This study aims to formulate raloxifene loaded lipid-polymeric hybrid nanoparticles (LPHNPs) and the comparison of their properties. Three LPHNPs, each with phosphatidylcholine-lipid (PCL) as bilayer-formingmembrane with three different polymers like sodium alginate, chitosan and poly(lactic-co-glycolic-acid) were prepared by nanoprecipitation, solvent injection and emulsion solvent evaporation, respectively. Results showed that the prepared formulations were spherical-shaped with a heterogeneity. Surface morphology was viewed using a scanning electron microscopy (SEM). A high entrapment efficiency (>70%) with a sustained and pH dependent drug release profile for 24 h was observed and evaluated using mathematical kinetic modelling. Fourier transform infrared spectroscopy was used to confirm successful entrapment of raloxifene after evaluating the interaction and compatibility of the excipients used. Whereas, differential scanning calorimetry and X-ray diffraction revealed the transformation of raloxifene into an amorphous form. In conclusion, these hybrid nanoparticles provide a promising approach for oral delivery of raloxifene. © 2020 Inderscience Enterprises Ltd.

This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics-Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs are employed to solve Nordgren’s equation, which governs fracture width evolution, by embedding physical laws into the neural network architecture. Using TensorFlow on Google Colab, the PINN training process incorporates Adam, L-BFGS, and Newton-CG optimizers, achieving an accuracy of 1.23x10−9 for fluid viscosity µ = 8.0 Pa.s, fracture height H = 2.0m, and leak-off coefficient CL = 1.0. However, this approach demands significant computational resources, with training times exceeding 1454 seconds and memory usage of 1136 MB in some cases. Conversely, the VQE framework leverages Qiskit on Qbraid to optimize the Hamiltonian representing the fracture system. With qubit-based ansatz circuits and classical optimizers (SPSA, COBYLA, and L-BFGS), VQE achieves rapid energy minimization, converging to approximately -0.583+0j in under 2 seconds with negligible memory requirements. Spatiotemporal fracture width predictions from VQE align well with expected trends but exhibit slight oscillations due to quantum noise. This comparative study highlights the trade-offs where PINNs excel in accuracy and physical adherence, while VQE offers unparalleled efficiency for rapid computations. The hybrid application of PINN precision and VQE speed provides a robust toolkit for optimizing hydrocarbon recovery. Future research will explore integrating these paradigms for scalable, high-fidelity simulations across complex geological settings. © 2025, CC BY.

The role of Gemini surfactant and SiO2/SnO/Ni2O3 nanoparticles as flow improver of Malaysian crude oil

引用

Journal of King Saud University - engineering Sciences 2022年第7期34卷 384-390页

作者： VijayaKumar, S.D. Zakaria, J. Ridzuan, N. Faculty of Chemical Process Engineering Technology Universiti Malaysia Pahang Lebuhraya Tun Razak Pahang Kuantan26300 Malaysia

The addition of surfactants and nanoparticles in minimizing wax deposition related problems such as flow assurance is considered an attractive alternative among other techniques but limited researches have been carried out in investigating the method. High viscosity crude oil needs to be treated with viscosity reducer to facilitate transportation and processing. In this study, the efficiency of the viscosity reducer, a Gemini surfactant 2,5,8,11 Tetramethyl 6 dodecyn-5,8 Diol Ethoxylate, three different nanoparticles: silicon dioxide (SiO2), tin oxide (SnO) and nickel (III) oxide (Ni2O3) and their novel blends at different range of concentration, temperature, shear rate and surfactant/nanoparticle loading ratio are assessed in order to study their influence on the viscosity of Malaysian crude oil using Brookfield DV-III viscometer. The separate use of Gemini surfactant and nanoparticles alone resulted in significant reduction in crude oil viscosity. The combined use of Gemini surfactant and nanoparticles showed better performance as compared to their corresponding individual use. The presence of surfactant improves the adsorption of nanoparticles by functionalizing their surfaces. Adsorption and adhesion of wax molecules onto the surface of nanoparticles and surfactants prevents them from aggregating. This results in increment in viscosity reduction. Overall, the viscosity of crude oil was reduced about 85–92% at 10 ℃ with the aid of Gemini surfactant and nanoparticles. The highest viscosity reduction obtained was 92.8% using the blend of Gemini surfactant and silicon dioxide. The findings of the study are expected to contribute to the crude oil industry in improving flow in production and transportation. © 2021 The Authors

This review provides a comprehensive overview of recent progress in Mo2Ti2C3Tx research, focusing on synthesis strategies, structural characteristics, and energy storage and conversion capabilities. The key aspects discussed include the intrinsic structural and electrochemical properties of the material, which contribute to its outstanding performance in supercapacitors, lithium-ion batteries, and electrocatalytic applications. Their high electrical conductivity, large surface area, and chemical stability underlie their efficiency in these applications. In addition, its thermoelectric potential, which is highlighted by its high Seebeck coefficient and power factor, makes it a promising energy-harvesting material. Despite these advantages, challenges remain in achieving scalable production, long-term operational stability, and comprehensive mechanistic understanding of interfacial processes and degradation pathways. Future research should prioritise hybrid architectures combining Mo2Ti2C3Tx with polymers, 2D materials, or metal oxides to intensify synergistic effects, as well as computational modelling to unravel the structure-property relationships. Addressing scalability through eco-friendly, high-yield synthesis routes is pivotal for the transition of laboratory-scale innovations into commercial applications. By summarising recent advancements and identifying critical research gaps, this review aims to facilitate further development and practical use of Mo2Ti2C3Tx MXene in next-generation energy technologies. © 2025

Influence of internal intermittency on drop breakage and coalescence in turbulent liquid-liquid dispersion 15

15th European Turbulence Conference, ETC 2015

作者： Podgórska, Wioletta Faculty of Chemical and Process Engineering Warsaw University of Technology Warsaw Poland

Break-up and coalescence of droplets in stirred dispersion is considered and the influence of highly intermittent nature of turbulence on scale-up is discussed. Droplet breakup occurs when disruptive stresses overcome the stabilizing ones. Three different situations are taken into account: (a) pure liquid-liquid system with dispersed phase of low viscosity in which the only disruptive stress is due to pressure fluctuations and stabilizing stress is due to interfacial tension, (b) pure system with dispersed phase of high viscosity in which viscous stress generated within the drop increases stabilizing effect, (c) system with surfactant and additional disruptive stress. In all cases internal intermittency causes faster breakage in larger scale when average energy dissipation rate in the tank is maintained. Additionally, for system (a) coalescence was taken into account. In this system drop interfaces are partially mobile and coalescence is faster in larger scale due to intermittency. © TU Delft.
