        <description><![CDATA[An eco-friendly strategy was developed for the preparation of silver and copper nanoparticles using Tecoma stans (TS) flower extract. The synthesized nanostructures exhibited predominantly spherical morphologies, with particle sizes of 9.8 nm and 3.6 nm for silver and copper, respectively. The X-ray diffraction (XRD) analysis confirmed the face-centered cubic (fcc) of the nanoparticles. The catalytic activity of prepared nanoparticles was assessed toward 4-nitrophenol (4-NP) reduction under the presence of NaBH4. Compared with sivler nanoparticles, the copper nano catalysts demonstrated excellent catalytic activity achieving rapid conversion of 4-NP to 4-aminophenol (4-AP) with 93.5% catalytic efficiency. Furthermore, the catalysts demonstrated good reusability, and retaining the conversion efficiency of 95% even after five reaction cycles. The environmentally friendly synthesis, high catalytic performance, and recyclability highlight the ability of Ag and Cu nanoparticles for diverse catalytic applications.]]></description>

        <description><![CDATA[Energy transition is a global transformation driven by greenhouse gas climate change in which fossil power production is replaced by fully renewable counterparts. Currently, the world has accomplished a small fraction of the energy transition. The main reason is that fossil energy sources are still abundant, cost-effective, portable, and easily implementable, while renewable sources are still technologically incipient, costly, cumbersome, portable, intermittent/seasonal, and land-intensive. Because the world cannot suddenly get rid of fossil power production, the compromise is to convert it into sustainable production by attaching carbon abatement processes (anti-carbon packages). Moreover, it is also conducive to migrating from carbon-intensive fossil power production to less carbon-intensive ones. This trend is perceptible as coal-fired plants are being replaced by natural gas combined cycles characterized by maximum thermodynamic yields and minimum carbon emitted per kWh among all fossil analogs. Thus, a conceivable next step of energy transition is to implement natural gas combined cycles with anti-carbon packages. This work compares three anti-carbon packages—post-combustion, oxy-combustion, and pre-combustion—attached to a typical natural gas combined cycle. A differential is the novel marginal abatement cost (MAC) adopted as an economic-environmental performance metric. It is shown that the post-combustion combined cycle requires the minimum investment (596.89 MMUSD) and attains the maximum net value (2,060.68 MMUSD) and minimum MAC (4.58 USD/tCO2), making it the best economic-environmental compromise. The oxy-combustion combined cycle attains the maximum investment (1,095.19MMUSD) and intermediary MAC (12.09 USD/tCO2) and net value (1,144.21 MMUSD) but offers the best social benefit per environmental harm (PowerExported/CO2Emitted= 51.63 MWh/tCO2). The pre-combustion combined cycle has a minimum net value (339.66 MMUSD) and a maximum MAC (28.17 USD/tCO2) and is likely the worst decarbonized combined cycle according to all metrics.]]></description>

        <description><![CDATA[This study investigates how alumina nanoparticles, gum Arabic, and the surfactant 2-ethyl-1-hexanol influence the surface tension of aqueous lithium bromide (LiBr) solutions. Since surface tension, governed by intermolecular attractive forces at the liquid–solid interface, plays a key role in the performance of heat and mass transfer binary fluids, composed of water and LiBr; understanding these effects is critical for optimizing thermal systems. Lithium bromide–based heat transfer fluids were prepared from 55 wt% aqueous LiBr solutions containing alumina nanoparticles (20 nm), gum Arabic as a dispersion stabilizer, and/or 2-ethyl-1-hexanol as a surfactant. Surface tension measurements were conducted over a temperature range of 293–373 K for different fluid compositions: base LiBr solution, LiBr with nanoparticles, LiBr with gum Arabic, and LiBr with both nanoparticles and gum Arabic, with and without surfactant. The base aqueous LiBr solution exhibited surface tension values from 90.6 mN/m at 293 K to 82.7 mN/m at 373 K. The addition of alumina nanoparticles increased the surface tension by an average of 2.5%, whereas gum Arabic decreased it by approximately 2.1%. The introduction of the surfactant 2-ethyl-1-hexanol, regardless of the presence of nanoparticles or gum Arabic, led to a substantial reduction in surface tension of 32%–35%.]]></description>

        <description><![CDATA[The detection of volatile organic compounds (VOCs), particularly acetone, is crucial for environmental monitoring and biomedical diagnostics. In this study, Mg-substituted PrFeO3 perovskite oxides (PrMgxFe1-xO3, x = 0.1, 0.2, 0.3) were synthesized via a sol-gel auto-combustion route using Fe and Mg precursors extracted from waste-derived materials, offering a sustainable and cost-effective synthesis pathway. Pristine PrFeO3 exhibited p-type semiconducting behavior; however, Mg incorporation induced a shift to n-type conduction, attributed to the generation of oxygen vacancies and Fe3+/Fe2+ charge compensation. Gas sensing measurements conducted between 60 °C and 210 °C identified 150 °C as the optimal operating temperature. The x = 0.3 composition demonstrated the highest response to acetone, with rapid response (33 s) and recovery (20 s) times. The sensor exhibited excellent repeatability at 50 ppm acetone, moderate selectivity toward ethanol, propanol, and DMF, and demonstrated good long-term stability. The VOC sensing performance is attributed to defect engineering via Mg substitution, increased oxygen vacancy concentration, and improved charge carrier dynamics. These results highlight the potential of waste-integrated perovskite sensors in advancing sustainable gas-sensing technologies.]]></description>

        <description><![CDATA[A review of the recent developments in the field of lasing with liquid crystals (LCs) is presented. After an introduction into the principle of lasing the different relevant liquid crystal phases to the field are introduced, namely, the nematic and chiral nematic phase, Blue Phases, twist grain boundary and ferroelectric liquid crystals. The classic examples of liquid crystal lasing are shortly discussed, together with a variety of possibilities for tuning the lasing wavelength, before the modern trends in LC lasing are discussed in detail. These are particularly random lasers, where the effects of nanoparticles, quantum dots and solitons are highlighted, as well as localized surface plasmon resonance. Other modern laser systems that have attracted recent interest, white lasers, whispering gallery mode lasers and those with biological materials, for example, cellulose nanocrystals, are also introduced and the latest developments outlined.]]></description>

        <description><![CDATA[Microemulsions (μEs) are particularly suitable systems for the efficient delivery of anticancer drugs due to their thermodynamic stability, structural flexibility, and patient-friendly chemotherapies. Moreover, μE formulations can efficiently encapsulate the anticancer drugs and deliver them to the desired location. Herein, three new Tween-60-based µE formulations were developed to enhance the dissolution profile of anticancer methotrexate (MTX). For this, μE formulations using an appropriate ratio of castor oil (∼9%), water (∼11%), and Tween-60 (∼40%) were used, while ethanol, 2-propanol, and 1-butanol were selected as co-surfactants for each formulation, respectively. Preliminarily, the phase compatibility of the μE ingredients, the average μE region, and the structural transformation in the microstructure of μE were delineated by mapping the pseudoternary phase diagram, as well as electrical conductivity, viscosity, and optical microscopic measurements. The size distribution profile of the as-formulated μEs analyzed by dynamic light scattering (DLS) revealed the fine monomodal assembly of MTX-μE nanodroplets (∼65 nm), which remained stable over a half year of storage. FTIR analysis showed good compatibility of MTX with μE ingredients with no apparent chemical interaction, while fluorescence measurements endorsed the acquisition of MTX in nonpolar microenvironments. Furthermore, an enhanced dissolution rate (>98% ± 1.5%, p ≤ 0.001) and superior bioavailability of the lyophilized non-aggregated methotrexate nanoparticles (MTX-NPs) were achieved, making them a suitable formulation for oral administration.]]></description>

        <description><![CDATA[Aqueous Zinc Ion Batteries (ZIBs), characterized by their high theoretical capacity, cost-effectiveness, and robust safety profile, stand out as one of the most promising contenders for the next-generation of electrochemical energy storage applications. Nevertheless, the commercialization of ZIBs encounters obstacles of unsatisfactory energy density and suboptimal cycling stability, which are related to the unstable interfaces of Zn anodes and cathodes. Herein, the research advances in Zn anodes and cathode materials and corresponding interface engineering in recent years are systematically reviewed. The rationalization of these research can guide further investigations in the design of cathode/anode materials in ZIBs.]]></description>

        <description><![CDATA[Nitrification converts ammonium (NH4+) to nitrate (NO3−) using metalloenzymes, the activity of which depends on iron (Fe), molybdenum (Mo), and copper (Cu) availability. Iron-organic carbon coprecipitates (or Fe-OC flocs) are key byproducts of wastewater treatment industry and natural components of soil that may affect nitrification by changing the bioavailability of these metals. Here, we used flocs of different chemistry (aromatic and aliphatic) and known Fe and C composition to investigate their effects on nitrification in soils along a soil C gradient. Both aromatic and aliphatic flocs reduced net nitrification, but the magnitude of their effect was more pronounced in soils with low C content as opposed to those with high C content. Within each soil, both flocs reduced net nitrification similarly. In the presence of flocs, the bioavailability of Mo (assessed by changes in the concentration of water-soluble Mo) was dramatically decreased in low C soils, possibly because Mo was incorporated into or adsorbed to flocs or their decomposition products. In contrast, Mo bioavailability in high C soils was decreased to a lesser extent by flocs, likely because organic matter limited floc adsorption capacity and released Mo through mineralization. The depletion of bioavailable Mo by flocs in agricultural soils has the potential to impede soil nitrification and extend the residence time of NH4+ and its availability to plants and microbes.]]></description>

        <description><![CDATA[Polycrystalline compounds of lanthanum strontium manganite (La1-xSrxMnO3, LSMO) are widely used in electronic storage devices due to their minimal losses and electronic charge transport properties. In this study, we investigated how varying substitutions of Sr2+ for values of x = 0.0, 0.1, and 0.2 affected the tuning of the optical band gap and dielectric losses in La1-xSrxMnO3 nanoparticles. Synthesized samples were structurally analyzed via X-ray diffraction. A rhombohedral R3¯c crystal structure was confirmed for all prepared samples; crystallite size ranging from 15 nm to 20 nm was estimated along with other lattice parameters. Polygonal or hexagonal-like morphology was revealed by field emission scanning electron microscopy, with a moderate size distribution of nanoparticles affected by thinner grain boundaries in doped LSMO. Energy dispersive spectroscopy was employed to confirm the elemental composition of each compound, and the infrared spectrum indicated bonding in the fingerprint region It was observed that there was a significant reduction in the optical band gap, which was measured using ultraviolet spectrometer absorption data. The band gap decreased from 4.34 eV to 4.11 eV. This reduction was found to be related to the difference in refractive index, which was calculated using both Moss and Herve–Vandamme relations. In parallel, frequency-dependent dielectric analysis revealed that frequency was proportional to the increase in Sr content, inversely affecting dielectric loss. Moreover, the AC conductivity of the prepared samples increased with the rise in Sr content, as described by Johnscher’s universal power law in the region of high frequency.]]></description>

        <description><![CDATA[Microemulsions (μEs) are more effective than conventional formulations for ophthalmic use due to their optical transparency, thermodynamic stability, structural flexibility and higher bioavailability. In addition, μE formulations can increase the water solubility of the drug and improve drug absorption in the eye. Herein, we report the development of three new biocompatible μE formulations containing an antihypertensive drug brinzolamide (BZD) and their evaluation for topical ocular administration. For this, Formulations A, B and C were optimized using an appropriate ratio of isopropyl myristate (IPM) as oil phase, water as aqueous phase and 2-propanol as co-surfactant, while Tween-80, Tween-20 and Tween-60 were selected as surfactant for each formulation, respectively. Preliminary, pseudoternary phase diagrams were delineated and then electrical conductivity and optical microscopy were used to establish optimal formulation for each μE to upheld the appropriate amount of BZD, i.e., 2.0 wt%, 2.0 wt%, and 1.0 wt% in formulation A, B and C, respectively. Dynamic light scattering demonstrated very fine monomodal assembly of BZD-μE nanodroplets (∼50 nm), while FTIR analysis showed effective encapsulation of BZD into hydrophobic microenvironment with no observable chemical interaction between BZD and μE excipients, which was further verified by the peak-to-peak concomitant measurement of fluorescence. Further, in-vitro release of BZD-μE showed enhanced and persistent topical ocular administration (>99%) within 10 h demonstrating the appropriate formulation for topical instillation.]]></description>

The scanning electron microscope was used to characterize the morphology of particles and the dispersed state of ferrofluid, energy-dispersive spectroscopy was used to study the chemical composition of particles, fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis were used to study the coated effect of PFPE-acids on particles, vibrating sample magnetometer was used to research the magnetization curves of ferrite particles, and the rheological property of the ferrite ferrofluids was studied by a rheometer. The results show that Zn2+, Mn2+/Zn2+, and Dy3+ ions were doped in the ferrite nanoparticles with a size less than 50 nm. The four kinds of ferrite nanoparticles have the characteristics of super-paramagnetic materials, and the M-T curves decrease with increasing temperature, while their decline rates are notably different. The ferrite particles are coated with PFPE acids chemically, and the ferrofluids have well dispersion stability. The rheological properties of the ferrite ferrofluids change with the variation of ion doping, magnetic field strength, temperature, etc. The magnetism and viscosity of ferrite ferrofluids are regularly affected by ion doping, and the results will have a great significance on basic research and related applications.]]></description>

        <description><![CDATA[Significance: Bio-nanofluids have achieved rapid attention due to their potential and vital role in various fields like biotechnology and energy, as well as in medicine such as in drug delivery, imaging, providing scaffolds for tissue engineering, and providing suitable environments for cell growth, as well as being used as coolants in various energy systems, wastewater treatment, and delivery of nutrients to plants.Objective: The present study proposes a novel mathematical model for the ternary hybrid cross bio-nanofluid model to analyse the behaviour of blood that passes through a stenosed artery under the influence of an inclined magnetic field. The model considers the effect of expanding/contracting cylinder, infinite shear rate viscosity, and bio-nanofluids.Methodology: The considered model of the problem is bounded in the form of governing equations such as PDEs. These PDEs are transformed into ODEs with the help of similarity transformations and then solved numerically with the help of the bvp4c method.Findings: The results show that the flow rate and velocity decrease as the inclination angle of the magnetic field increases. Additionally, research has found that the presence of nanoparticles in the bio-nanofluid has a significant impact on the velocity and flow rate. Therefore, the flow rate decreases, in general, as the stenosis becomes more severe.Advantages of the study: The results obtained from this study may provide insights into the behaviour of blood flow in stenosed arteries and may be useful in the design of medical devices and therapies for the treatment of cardiovascular diseases.]]></description>

        <description><![CDATA[The present study demonstrates a novel photoanode layer double hydroxide (LDH) for dye-sensitized solar cells (DSSCs). The search for a photoanode (PA) with low cost and high power conversion efficiency (PCE) has become one of the most significant challenges facing researchers. LDH has proven successful as a photocatalyst in various fields. In this paper, a novel Cd-V-LDH with a molar ratio of Cd:V = 1:1 was synthesized by the coprecipitation method and used as a novel PA in DSSCS. X-ray diffraction (XRD), Raman spectroscopy, Scanning electron microscopy (SEM), Fourier Transform infrared spectroscopy (FTIR), Nitrogen sorption analysis, UV–Vis absorption spectrum, Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) were used to examine the produced Cd-V-LDH. Cd-V-LDH as PA, Eosin Y (EY) as a photosensitizer, LiI-I2 as a liquid electrolyte, and g-C3N4 (GN) as a photocathode (PC) are the component of DSSCs. The series cells of DSSCs were assembled and the available variables have been studied to achieve the best performance under normal conditions. These variables, e.g., concentration and pH of EY, active area of PA, and different types of PC, e.g., graphene oxide (GO), commercial carbon (CC), and (GN). The open circuit voltage (VOC) and short circuit current density (JSC) for the Cd-V-LDH/EY/LiI-I2/GN system were observed to be 705 mV and 12.40 mA/cm2, and has a PCE of 5.4% comparable to Cd-V-LDH/EY/LiI-I2/GO and Cd-V-LDH/EY/LiI-I2/CC, which have PCEs of 4.9% and 3.8%, respectively, in the identical testing conditions.]]></description>

        <description><![CDATA[Depletion attraction is a common entropy force observed in colloidal systems. As a common phenomenon in colloidal and bacterial systems, studying the mechanism and application of depletion attraction is of great value for controlling the state of colloidal solutions, regulating the morphology of colloidal particles, disease treatment, and water pollution treatment. Based on the current research status, we briefly introduce the calculation and measurement methods of depletion attractions. And we review the application of depletion attractions in colloidal systems, and summarize the different phenomena and aggregation mechanisms caused by depletion attraction in active colloidal particle-bacterial systems. Understanding the specific role of depletion aggregation in colloidal and bacterial systems provides more possibilities for further exploring depletion aggregation mechanisms and utilizing depletion aggregation phenomena in nature.]]></description>

        <description><![CDATA[This study examines the effects of a porous media and thermal radiation on Casson-based nano liquid movement over a curved extending surface. The governing equations are simplified into a system of ODEs (ordinary differential equations) using the appropriate similarity variables. The numerical outcomes are obtained using the shooting method and Runge-Kutta Fehlbergs fourth-fifth order (RKF-45). An analysis is conducted to discuss the impact of significant nondimensional constraints on the thermal and velocity profiles. The findings show that the rise in curvature constraint will improve the velocity but diminish the temperature. The increased values of the modified Hartmann number raise the velocity, but a reverse trend is seen for increased porosity parameter values. Thermal radiation raises the temperature, while modified Hartmann numbers and the Casson factor lower the velocity but raise the thermal profile. Moreover, the existence of porous and solid fractions minimizes the surface drag force, and radiation and solid fraction components enhance the rate of thermal dispersion. The findings of this research may have potential applications in the design of heat exchangers used in cooling electronic devices like CPUs and GPUs, as well as microscale engines such as microturbines and micro-heat engines.]]></description>
