Abstract ：
We present a novel design of a ferroelectric fast reactive tuner (FE-FRT) capable of modulating megaVAR reactive power on a submicrosecond timescale. The high reactive power capability of our design extends the range of applications of reactive tuners to numerous applications. We present a detailed analytical model of the performance of a megawatt-class reactive power device and benchmark it against finite-element method eigenmode and frequency domain electromagnetic simulations. We introduce new features, including an annulus design for the ferroelectric capacitors and capacitive window coupling to the cavity. We consider thermal design issues and nonlinear effects in the ferroelectric. The model covers several configurations, allowing control of the frequency of superconducting and normal-conducting cavities in a variety of applications and frequencies. We calculate that the FE-FRT designed should be capable of handling around 0.45 MVAR of reactive power with around 3 kW of resistive losses, providing a frequency tuning range of 8 kHz in an example of 400 MHz cavity geometry.

Abstract ：
Efficient removal of iron and aluminum impurities is critical for the extraction of lithium and rubidium from zinnwaldite, a lithium-bearing mineral. In this study, solvent extraction using P507 was employed to remove iron and aluminum from zinnwaldite leaching solutions. However, stripping iron from the organic phase proved challenging due to the strong interaction between iron ions and the extractant. To address this, a novel reduction stripping method was developed using ascorbic acid (AA) as a reductant. This method exploits the reduction of Fe3+ to Fe2+ in the aqueous phase, weakening the binding between iron ions and the organic phase, thus enabling efficient stripping. The optimized process achieved over 99.99% removal of iron and aluminum impurities. Subsequently, rubidium was selectively extracted using t-BAMBP, with a total recovery rate of 88.53%. Scaling-up experiments confirmed the feasibility of the process for industrial applications, demonstrating high efficiency and reagent recyclability. This study offers a promising approach for the efficient extraction and separation of valuable metals from zinnwaldite, with potential for broader applications in metal processing.

Abstract ：
Lithium and its associated rubidium are regarded as the strategic metal resource, which have a wide use in many commercial products. Nowadays, the continuing growth in demand for Li resources, propelling the object of industrial exploitation will focus on low-grade, complex minerals composition and unwieldy ores. Zinnwaldite has received increasing attention as a potential lithium-containing resource in recent years. However, there are a lack of effective extraction processes for zinnwaldite. Hence, this paper proposes an effective method to extract metal cleanly and efficiently from zinnwaldite by using CaO and B2O3 2 O 3 as thermal activation additives and H2SO4 2 SO 4 as the leaching agent. The results showed that the destruction of Fe-O and Si-O-Si bonds led to increased extraction efficiency. The breathing vibrations of oxygen atoms symmetric in 4- and 3-membered rings and Si-O symmetric stretch could influence the Li separation from silica skeleton. Ultimately, the 91.32 % Li, 93.09% Rb, 81.14 % Fe, 95.00 % Al and 71.12 % K were recovered under the optimal conditions. Meanwhile, about 10 % F escaped into the air during thermal activation and the concentration of F in the leaching solution was lower than 2 mg/L. The use of B2O3 2 O 3 provides a valuable reference for the efficient and clean treatment of lepidolite using the salt roasting method.

Abstract ：
Minimizing the dosage of toxic SeO2 additive in electrolyte for electrochemical deposition of metal manganese without compromising the current efficiency has long been the desire for electrolytic manganese industry. Herein, by combinative usage of SeO2 and gluconic acid (GlcA) as the composite additives, 50 % of SeO2 dosage can be cut down while the current efficiency can be increased from 67 % to 90 % at the same time, realizing the energy consumption being reduced by 23 % at the optimized concentration of 1.84 g/L GlcA. The electrochemical tests and electrode surface characterizations as well as density functional theory calculations jointly imply that the addition of GlcA can greatly increase the diffusion coefficient of Mn2+ from 1.5 × 10−6 cm2/s to 5.6 × 10−5 cm2/s, accelerating the approaching of Mn2+ towards the electrode surface by decreasing the diffusion barrier energy from 17.93 kJ/mol to 11.51 kJ/mol. On the electrode surface, the SeO32− is responsible for facilitating the electrochemical deposition of metal Mn by forming the MnSe intermediate while GlcA is in charge of restraining the activation of H2O molecule for inhibiting H2 generation, synergistically contributing to the efficient production of electrolytic metal manganese. The results can provide new insights for the environmentally friendly and high-efficiency upgrading of manganese industry. © 2024 Elsevier Ltd

Abstract ：
Electrolytic manganese is an important metal material that is widely employed in batteries, electronics, steel, and other fields. However, there are many issues regarding the production process of electrolytic manganese, such as low current efficiency, high-content toxic SeO2 additives in the electrolyte, and difficulty in controlling the product morphology. These issues not only impact the production efficiency and quality of electrolytic manganese but also result in severe environmental pollution. To address these issues, a MnSO4-(NH4)2SO4 electrolyte system was prepared based on the electrolytic manganese industry standard. The effects of polyacrylic acid, glycine, ethylenediaminetetraacetic acid (EDTA), and gluconic acid were explored as auxiliary additives under neutral electrolysis conditions to lower the SeO2 content, which is a highly toxic main additive. The effects of the different additives on the metal manganese morphology, crystal structure, and cathodic electrochemical polarization behavior were examined by field-emission scanning electron microscopy, X-ray diffraction, and constant current cathodic polarization curve tests. The findings reveal that the main orientation of the metal manganese crystal form deposited by the four auxiliary additives is the (330) crystal plane, and all of them can promote the formation of α-Mn, enhance the electrolysis efficiency, and lower the energy consumption. In particular, the optimized amount of polyacrylic acid of 0.08 g·L−1 contributes to an energy consumption of 5735.34 kW·h·t−1. Correspondingly, the addition of 10 g·L−1 glycine is the most favorable amount, leading to an energy consumption of 5518.56 kW·h·t−1. For EDTA, the lowest energy consumption of 5168.26 kW·h·t−1 is measured at an added amount of 0.5 g·L−1. Note that among the four investigated candidates, gluconic acid is the most favorable auxiliary additive, contributing to the increased cathode current density and reduced cathodic polarization as well as denser metal manganese products. Moreover, gluconic acid addition can lower the concentration of toxic SeO2 from 0.03-0.06 to 0.015 g·L−1, significantly increase the cathode current density, reduce the cathodic polarization, and result in a more dense and smooth product morphology, with the current efficiency being increased from approximately 70% to 89.73% and energy consumption being reduced from 6500 to 4990.58 kW·h·t−1 at the same time. Gluconic acid, as the auxiliary additive, not only contributes to the best electrolysis indexes for electrolytic manganese but also facilitates the formation of metal manganese with the most desirable crystal structure. This work offers novel insights into the environmentally friendly production and cheap electrodeposition of metal manganese for the electrolytic manganese industry. © 2024 Science Press.

Abstract ：
电解锰行业面临电效低、SeO_2添加剂剧毒且沉积产物形貌难控制等问题.为了提高电流效率以降低能耗、改善锰电沉积形貌及降低添加剂SeO_2的使用量，本文根据电解锰行业标准，配制MnSO_4–(NH_4)_2SO_4电解液体系，通过添加聚丙烯酸、甘氨酸、乙二胺四乙酸(EDTA)、葡萄糖酸等分别作辅助添加剂，探究其对锰沉积的影响以降低剧毒性主添加剂SeO_2的用量.采用场发射扫描电子显微镜(SEM)、X射线衍射分析(XRD)、恒电流阴极极化曲线测试方法 (LSV)等表征手段，研究金属锰沉积形貌、晶体结构、阴极电化学极化行为与添加剂之间的关系.结果表明：四种添加剂均可以促进α-Mn的形成，且最优晶型取向为(330)晶面，其中葡萄糖酸最适宜作为辅助添加剂.当以葡萄糖酸为辅助添加剂，质量浓度为1.84 g·L~(-1)时，阴极电流密度明显提高，降低了阴极极化，产品形貌更加致密光滑.最优条件下，SeO_2的质量浓度可由工业上常规用量0.03～0.06 g?L~(-1)降低至0.015 g?L~(-1)，电流效率可由70%提高至89.73%，能耗由6500 kW·h·t~(-1)降至4990.58 kW·h·t~(-1).研究结果有望为电解锰行业绿色生产和高效电沉积提供借鉴，有助于推动电解锰行业的可持续发展.

Abstract ：
Surface engineering of both morphology and composition is appealing strategy for further boosting the hydrogen evolution reaction (HER) performances of commercial bulk nickel electrode in alkaline media. However, modified surface structure with long-term stability is still in desperate need, especially at industrial-scale current density. Herein, by grafting the commercial nickel electrode with well-aligned nickel-rhenium (Ni–Re) alloy particles, the electrode surface turns to be highly hydrophilic, thus propelling the detachment of hydrogen (H2) bubbles from the electrode surface. In addition, the synergy within the dual Ni–Re atom optimizes the electronic structure of electrode surface, lowering the energy barriers for water dissociation. Resultantly, the NiRe-modified nickel bulk electrode shows fascinating HER performance in both activity and long-term stability, namely overpotential of 191 mV@100 mA cm−2, stable operation for 2000 h at 200 mA cm−2 in H-type cell, and steady running for >1000 h at 1000 mA cm−2 using the configuration of Ni||Ni-60 %Re in the membrane electrode assembly, outperforming that of the benchmark Pt/C catalysts. The results can provide new insights for the tradeoff between activity and cost towards high-performance alkaline water electrolysis. © 2024 Elsevier B.V.
