The mandarin peel is a valuable natural source of phenolic compounds known for their high antioxidant properties. Cloud point extraction (CPE) emerges as a groundbreaking technique for harvesting bioactives compounds. The optimal CPE conditions were 8.5 % (v/v) Triton X-114 at 30 °C with pH 4, and 7 % (w/v) salt concentration. At optimal CPE, 93.75 % phenolic compounds and 88.35 % flavonoids were recovered their respective yields of 16.85 mg gallic acid equivalent per gram and 2.45 mg quercetin equivalent per gram of mandarin peel. The micellar mandarin peel extract (MMPE) exhibited 47.05 % antioxidant activity. Further, MMPE was encapsulated in sodium alginate beads to improve its stability. The highest 74.05 % encapsulation efficiency was achieved using 2.5 % sodium alginate. The MMPE beads showed increased hardness due to rigid shell. Structural characterizations also explained more uniform and densely packed internal structure of MMPE beads compared to blank beads. Functional properties and thermal stability assessments showcased superior properties in MMPE beads. Release kinetics studies revealed that 60–70 % of polyphenols were liberated within 30 min under both aqueous and simulated gastric environments. CPE presents a promising avenue for converting mandarin peel waste into valuable bioactives with antioxidant properties.
柑橘皮是一种宝贵的天然酚类化合物来源,具有很高的抗氧化性。云点萃取(CPE)是获取生物活性化合物的突破性技术。CPE 的最佳条件为 8.5 %(v/v)的 Triton X-114,温度为 30 °C,pH 值为 4,盐浓度为 7 %(w/v)。在最佳 CPE 条件下,酚类化合物的回收率为 93.75%,黄酮类化合物的回收率为 88.35%,每克柑橘皮的产量分别为 16.85 毫克没食子酸当量和 2.45 毫克槲皮素当量。胶束柑皮提取物(MMPE)显示出 47.05% 的抗氧化活性。此外,为了提高稳定性,还将 MMPE 封装在海藻酸钠珠中。海藻酸钠含量为 2.5%,封装效率最高,达到 74.05%。由于外壳坚硬,MMPE 珠的硬度有所提高。结构表征还表明,与空白珠子相比,MMPE 珠子的内部结构更加均匀和致密。功能特性和热稳定性评估显示了 MMPE 珠的优异特性。释放动力学研究表明,在水环境和模拟胃环境下,60-70% 的多酚在 30 分钟内释放。CPE 为将柑皮废弃物转化为具有抗氧化特性的宝贵生物活性物质提供了一条前景广阔的途径。

Fruit processing by-products, especially peels are underused and mostly discarded as waste. The aim of this study was to assess the effect of ultrasonication (US) combined with carbonation (CUS) on the convective drying process of avocado peels at different temperatures, adding value to this waste. For this, the avocado peels were treated with dry ice for 15 min and subjected to US (400 W/10 min, 30 °C) before convective air drying (50–70 °C). The energy consumption, antioxidant capacity, water adsorption isotherms, rehydration rate, and dynamic rheology of dried avocado peels pretreated by CUS were compared with a control process (without pretreatment) and only US pretreatment. The combined treatment (CUS70) resulted in a 2.6-fold reduction in drying time and a 2.3-fold decrease in energy consumption, with CO2 preserving bioactive compounds and antioxidant capacity after the drying process. Differences were also observed in the rehydration capacity of the samples (CUS), with an increased water absorption capacity, along with a reduction in the viscoelastic properties of the peels. The results present new perspectives for the application of CUS in the food industry, paving the way for the development of creative, innovative, and simple approaches for the management and recycling of agri-food waste, with the potential to extend this knowledge to new food matrices.
水果加工的副产品,尤其是果皮,利用率很低,大多作为废物丢弃。本研究旨在评估在不同温度下超声波(US)结合碳酸化(CUS)对牛油果皮对流干燥过程的影响,从而增加这种废物的价值。为此,在对流空气干燥(50-70 °C)之前,先用干冰处理牛油果皮 15 分钟,然后进行超声波处理(400 瓦/10 分钟,30 °C)。将经 CUS 预处理的牛油果干皮的能耗、抗氧化能力、水吸附等温线、复水率和动态流变性与对照工艺(无预处理)和仅经 US 预处理的牛油果干皮进行了比较。综合处理(CUS70)使干燥时间缩短了 2.6 倍,能耗降低了 2.3 倍,干燥过程后二氧化碳保留了生物活性化合物和抗氧化能力。此外,还观察到样品(CUS)的再水化能力不同,吸水能力增加,果皮的粘弹性降低。这些结果为 CUS 在食品工业中的应用提供了新的视角,为开发具有创造性、创新性和简便性的农业食品废弃物管理和回收方法铺平了道路,并有可能将这些知识推广到新的食品基质中。

In droplet-based microfluidics, rapid mixing during droplet formation enhances reaction uniformity, eliminating the need for micromixers. In this research, we conducted a comprehensive study by first employing a series of two-dimensional (2D) numerical simulations, followed by experimental investigations using 3D-printed microfluidic chips. We compared the mixing efficiency, droplet diameter, and droplet eccentricity of three different types of droplet generators: T junction, cross junction, and asymmetric droplet generators with various angles. Regarding mixing efficiency, we observed that the asymmetric droplet generators outperformed the cross junction by 30 % but fell slightly short of the mixing efficiency achieved by the T junction (1 %). Additionally, while the mixing index in the asymmetric generators closely matched that of the T junction, these asymmetric generators produced smaller droplets by 72 %. Increasing the angle in asymmetric droplet generators resulted in enhanced mixing efficiencies and an increase in droplet diameters. The asymmetric junction with a 30° angle could achieve a mixing efficiency of up to 80 %. Additionally, an analysis of the dispersed phase flow rate revealed that higher flow rates lead to larger droplet sizes and reduced mixing efficiencies. The asymmetric droplet generators improve mixing efficiency facilitating rapid reagent mixing, all while maintaining a small droplet diameter.
在基于液滴的微流控技术中,液滴形成过程中的快速混合可提高反应的均匀性,从而无需使用微搅拌器。在这项研究中,我们首先进行了一系列二维(2D)数值模拟,然后利用三维打印微流控芯片进行了实验研究。我们比较了三种不同类型液滴发生器的混合效率、液滴直径和液滴偏心率:我们比较了三种不同类型的液滴发生器的混合效率、液滴直径和液滴偏心率:T 型结点、交叉结点和不同角度的不对称液滴发生器。在混合效率方面,我们观察到非对称液滴发生器的混合效率比交叉接合器高 30%,但与 T 型接合器的混合效率(1%)相比略有差距。此外,虽然非对称液滴发生器的混合指数与 T 型结点的混合指数非常接近,但这些非对称液滴发生器产生的液滴却比 T 型结点小 72%。增大非对称液滴发生器的角度可提高混合效率并增加液滴直径。角度为 30° 的不对称接合处的混合效率可达 80%。此外,对分散相流速的分析表明,流速越高,液滴尺寸越大,混合效率越低。不对称液滴发生器提高了混合效率,有利于快速混合试剂,同时保持较小的液滴直径。

This paper presents a novel gas-liquid separator characterized by its distinctive geometric design, capable of handling different volume fractions and mass flow rates. The separator's performance is comprehensively assessed across various gas volume fractions, bubble sizes, and mass flow rate fluctuations. The study reveals that variations in vapor volume fraction substantially affect both separation efficiency and pressure loss. An increase in vapor volume fraction from 0.1 to 0.5 leads to a 25% reduction in separation efficiency and a 3.3-fold decrease in pressure loss. In contrast, changes in mass flow rate exert a relatively minor influence on separation efficiency. Specifically, increasing the mass flow rate from 15 to 30 kg/s results in a mere 4% decrease in separation efficiency, whereas pressure loss increases by a factor of 3.2.
Additionally, a reduction in bubble size from 1000 µm to 200 µm causes a 33% increase in pressure loss and a 14% decrease in separation efficiency. The incorporation of a meshpad in this design promotes the formation of a forced vortex, thereby enhancing the separation process.
本文介绍了一种新型气液分离器,其独特的几何设计能够处理不同的体积分数和质量流量。本文全面评估了该分离器在不同气体体积分数、气泡大小和质量流量波动下的性能。研究表明,蒸汽体积分数的变化对分离效率和压力损失都有很大影响。蒸汽体积分数从 0.1 增加到 0.5 会导致分离效率降低 25%,压力损失减少 3.3 倍。相比之下,质量流量的变化对分离效率的影响相对较小。具体来说,质量流量从 15 千克/秒增加到 30 千克/秒,分离效率仅降低 4%,而压力损失却增加了 3.2 倍。此外,气泡尺寸从 1000 微米减小到 200 微米,会导致压力损失增加 33%,分离效率降低 14%。在这种设计中加入网垫可促进强制涡流的形成,从而增强分离过程。

The oxygen reduction reaction (ORR) is fundamental in numerous electrochemical energy conversion technologies, necessitating efficient catalysts to enhance reaction kinetics and reduce precious metal usage. This study focuses strategic clustering of Pt-Ni on Calcium Oxide/activated carbon (C/Ca) aerogels. Electrochemical analyses confirmed that incorporating Ni into Pt matrices significantly enhanced ORR activities with Pt25Ni75-C/Ca composition emerged as optimum. A positive shift in half-wave potential (905 mV vs. RHE) and impressive mass activity (72.50 Ag−1 at 85 V) highlight the potential of this composite as a highly effective and stable ORR catalyst. Pt-C/Ca demonstrated performance fluctuation, while Pt25Ni75-C/Ca showed remarkable stability after 40,000 cycles. Furthermore, C/Ca aerogels exhibited a significantly increased BET surface area, and the presence of Pt-Ni/pyridinic-N species on its surface C/Ca aerogel provided supplementary active sites that facilitated the adsorption and reduction of O2 during ORR.

In this paper, we propose a micromixer with the combination of a flow-focusing region and sawtooth structures, to study the mixing performance of electrokinetic (EK) flow under the impact of an alternating current (AC) electric field by means of numerical simulations. The Helmholtz-Smoluchowski theory is applied to approximate the electric double layer (EDL) effect. Focusing on the effects of sawtooth structures and AC electric field frequencies on mixing efficiency of electrokinetic micromixers, the concentration distributions and velocity distributions within micromixers have been studied. The numerical simulation results demonstrate that this micromixer has an excellent mixing performance for Newtonian solutions. Additionally, a proper sawtooth structure is conducive to enhancing the mixing efficiency of an electrokinetic micromixer, which is due to the generation of vortices at the junction edges. The presence of vortices leads to the enhancement of fluid disturbance and the enlarged contact area between fluids, contributing to a more complete mixing for electrokinetic flows. Moreover, it is found that as the AC electric frequency is reduced, the mixing efficiency is enhanced for such novel electrokinetic micromixer. The low electric frequency causes the velocity of electro-osmotic flow to decrease, promoting the molecular diffusion as the primary mixing mechanism, which improves the mixing efficiency.

本文提出了一种结合了流动聚焦区和锯齿结构的微搅拌器,通过数值模拟研究了交流电场影响下的电动(EK)流的混合性能。亥姆霍兹-斯莫卢霍夫斯基理论被用于近似电双层(EDL)效应。重点研究了锯齿结构和交流电场频率对电动微搅拌器混合效率的影响,以及微搅拌器内的浓度分布和速度分布。数值模拟结果表明,这种微搅拌器对牛顿溶液具有出色的混合性能。此外,适当的锯齿结构有利于提高电动微搅拌器的混合效率,这是由于在交界边缘产生了涡流。涡流的存在会增强流体扰动,扩大流体间的接触面积,从而使电动流的混合更加完全。此外,研究还发现,随着交流电频率的降低,这种新型电动微混合器的混合效率也会提高。低电频导致电渗流速度降低,促进分子扩散成为主要的混合机制,从而提高了混合效率。这项工作为锯齿结构在电动微搅拌器上的应用提供了重要启示,并为微流控技术中主动与被动技术的整合提供了重要参考。

Focusing on the effects of sawtooth structures and AC electric field frequencies on mixing efficiency of electrokinetic micromixers, the concentration distributions and velocity distributions within micromixers have been studied. The numerical simulation results demonstrate that this micromixer has an excellent mixing performance for Newtonian solutions. Additionally, a proper sawtooth structure is conducive to enhancing the mixing efficiency of an electrokinetic micromixer, which is due to the generation of vortices at the junction edges. The presence of vortices leads to the enhancement of fluid disturbance and the enlarged contact area between fluids, contributing to a more complete mixing for electrokinetic flows.

With the depletion of traditional fossil fuel and the increasingly severe problem of carbon emissions, the world urgently seeks alternative energy sources. Biodiesel, with its clean and renewable characteristics, has become an ideal alternative to fossil fuel. The “temperature difference driven heating-mechanical stirring-heterogeneous catalytic transesterification” process is supposed to be an ideal technology for biodiesel production, but there is a large resistance to heat and mass transfer in this way, which leads to slow catalytic reaction rate and low biodiesel yield. To solve this process, researchers have innovatively introduced external field-enhanced technologies such as microwave and ultrasound, aiming to enhance heat and mass transfer processes, optimize reaction conditions and significantly improve biodiesel yield. This article deeply analyzes the principles of heterogeneously catalyzed transesterification reaction enhanced by external fields and their positive effect on reaction kinetics and thermodynamics. Furthermore, the performance of external field-enhanced technologies is comprehensively analyzed in terms of techno-economic, environmental and bibliometric mapping. Finally, the future application of external field-enhanced technologies in biodiesel production is prospectively discussed.

随着传统化石燃料的枯竭和碳排放问题的日益严重,全世界都在迫切寻求替代能源。生物柴油以其清洁和可再生的特点,成为化石燃料的理想替代品。温差驱动加热-机械搅拌-均相催化酯交换 "工艺本应是生产生物柴油的理想技术,但这种方式存在较大的传热传质阻力,导致催化反应速度慢,生物柴油产量低。为解决这一工艺问题,研究人员创新性地引入了微波、超声等外场增强技术,旨在强化传热传质过程,优化反应条件,显著提高生物柴油收率。本文深入分析了外场增强异构催化酯交换反应的原理及其对反应动力学和热力学的积极影响。此外,还从技术经济、环境和文献图谱等方面全面分析了外场增强技术的性能。最后,对外部场增强技术在生物柴油生产中的未来应用进行了展望。

In recent years, the demand for phosphoric acid, a key raw material for lithium iron phosphate batteries, has surged. However, current phosphoric acid extraction equipment faces challenges such as low mass transfer efficiency and difficulty in phase separation, leading to reduced production efficiency, bulky equipment, and scaling issues. To address these problems, this study introduces a T-type central plug-in microreactor (TCPM) designed to enhance mass transfer efficiency and facilitate rapid phase separation. The extraction of phosphoric acid from the water phase to the organic phase (volume ratio of tributyl phosphate to kerosene is 4:1) was chosen as the experimental system. We investigated the effects of various parameters on liquid-liquid flow and mass transfer characteristics in the TCPM. Visualization techniques identified slug and parallel flow as the primary liquid-liquid flow patterns within the TCPM. Notably, the central plug-in promotes the formation of parallel flow, improving phase separation compared to conventional T-type microreactors. The volume mass transfer coefficient of the TCPM ranges from 0.023 to 0.074 s-1, and the optimal phosphoric acid extraction efficiency and volume mass transfer coefficient can reach up to 90.5% and 0.074 s-1, respectively, outperforming conventional T-type microreactors. Predictive model for extraction efficiency was developed, showing deviations within 10%. These findings demonstrate the TCPM's potential as an efficient phosphoric acid extraction device with rapid phase separation, holding significant promise for liquid-liquid extraction applications.

近年来,磷酸铁锂电池的关键原材料磷酸的需求激增。然而,目前的磷酸萃取设备面临着传质效率低、相分离困难等挑战,导致生产效率降低、设备笨重、扩展困难等问题。为解决这些问题,本研究引入了一种 T 型中央插入式微反应器(TCPM),旨在提高传质效率并促进快速相分离。实验系统选择了磷酸从水相萃取到有机相(磷酸三丁酯与煤油的体积比为 4:1)的过程。我们研究了各种参数对 TCPM 中液-液流动和传质特性的影响。可视化技术确定了 TCPM 中主要的液-液流动模式为蛞蝓流和平行流。值得注意的是,与传统的 T 型微反应器相比,中央插件促进了平行流的形成,改善了相分离。TCPM 的体积传质系数范围为 0.023 至 0.074 s-1,最佳磷酸萃取效率和体积传质系数分别高达 90.5% 和 0.074 s-1,优于传统的 T 型微反应器。建立的萃取效率预测模型显示,偏差在 10% 以内。这些研究结果表明,TCPM 具有作为快速相分离的高效磷酸萃取装置的潜力,在液-液萃取应用中大有可为。
