Profiting from the co-sensitization of AgInS₂ and CuInS₂ on paper-based ZnO, the dual NIR-response cascade sensitization structure of AgInS₂/CuInS₂/ZnO exhibited a wide light response range and high charge separation efficiency, giving a “switch on” state of co-sensitization effect with markedly high photocurrent response. The “switch off” state of the co-sensitization effect was made by RecJf exonuclease-assisted target recycling-induced conformation change of THMS, which caused the detachment of AgInS₂ quantum dots from the aptasensing interface, leading to a significantly decreased photocurrent signal. Accordingly, the constant <i>I</i>₁ of PWE₁ and varying <i>I</i>₂ of PWE₂ were collected based on the incubation of constant concentration of DEHP on PWE₁ and various concentrations of DEHP on PWE₂. The ultrasensitive detection of DEHP was realized by calculating the ratio of <i>I</i>₂/<i>I</i>₁. This work brought new insights into the establishment of a high-performance paper-based ratiometric PEC aptasensing platform for highly sensitive quantification of DEHP.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"9 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complex forms of occurrence of vanadium in black shale, particularly its incorporation into aluminosilicate mica via isomorphism, render it tightly bound and challenging to extract. Against the backdrop of green metallurgy and the “Double Carbon” initiative, methodologies such as the new roasting process, the whole hydrometallurgical process, and biological leaching have been developed, with their mechanisms thoroughly examined. This review examines the mechanisms of each process, highlighting that enhanced vanadium leaching is primarily achieved by disrupting the covalent bonds in vanadium-containing mica or by oxidizing lower-valence vanadium. However, the leaching mechanism of autotrophic microorganisms for black shale remains unclear. Drawing from various studies, a mechanism involving the cooperative action of iron-oxidizing and sulfur-oxidizing bacteria in the leaching of black shale is proposed. A comparative analysis of these enhancement processes reveals that microbial technology offers benefits such as environmental sustainability, low carbon footprint, minimal pollution, and scalability, marking it a promising area for research and application. However, the technological processes and mechanisms underlying microbial leaching of black shale require further elucidation. Future studies should focus on developing highly efficient leaching bacteria, exploring the synergistic effects between microorganisms and examining the mechanisms of biological leaching to provide technical and theoretical foundations for efficient and eco-friendly microbial extraction of vanadium from black shale.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"41 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is observed that the Nb/TiNb nanocomposite possesses a high yield strength of ~ 640 MPa, significantly exceeding that of the conventional single-phase β-type Ti alloys. Further experimental results indicate that as plastic deformation commenced in the TiNb matrix of Nb/TiNb nanocomposite, load transfer from the soft TiNb matrix into the reinforced Nb nanowires occurred, allowing for a high load-bearing stress contribution and a significant strength enhancement of Nb/TiNb nanocomposite. Meanwhile, the embedded Nb nanowires can effectively impede the propagation of dislocation in TiNb matrix, further strengthening the present nanocomposite.

This paper proposes an efficient strategy to address these critical issues for realizing long-life and high-capacity aqueous zinc-ion hybrid supercapacitors (ZHSCs) by incorporating low-concentration (0.05 mol·L⁻¹) redox RbI electrolyte additives. Specifically, rubidium cations have the ability to influence the negative Zn electrode surface via an electrostatic shielding mechanism, effectively protecting the electrode and minimizing undesired side reactions. In an aqueous solution, iodide anions actively solvate Zn²⁺ ions by stabilizing and modulating the solvation shell surrounding Zn²⁺. Moreover, the presence of iodide ions promotes the uniform deposition of Zn²⁺ species by selective adsorption onto the electrode surface. The synergistic effect of the electrostatic shielding and halogen ions enables the realization of aqueous symmetric Zn||Zn cells with a substantial cycle life of more than 2000 h. Additionally, when applied to commercial activated carbon (AC), the proposed strategy facilitates the development of aqueous ZHSCs, exhibiting high specific capacitances (148.8 F·g⁻¹ at 4 A·g⁻¹) and ultra-long cycling stability.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"43 10","pages":"5060 - 5069"},"PeriodicalIF":9.6,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141718736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate how various pre-tension strains (0%, 4% and 6%) influence the torsional properties, deformation and fracture mechanism of the Ti–5Al–5Mo–5V–3Cr–1Zr (Ti-55531) alloy with the bimodal microstructure. The results indicate that increasing the pre-tension strain gradually decreases the torsional strength of specimens. However, their torsional ductility initially increases (from 0 to 4% pre-tension strain) and then decreases (from 4 to 6% pre-tension strain). This can be attributed to the significant influence of different pre-tension strains on the deformation mechanism of each phase in the alloy. Under pure torsion loading, the primary α (α_p) phase mainly undergoes the {0002} basal slip for deformation. However, at a pre-tension strain of 4%, the torsional deformation mechanism of α_p transforms into crossing reaction between the {<span>(10overline{1 }0)</span>} prismatic slips. As the pre-tension strain further increases to 6%, {<span>(10overline{1 }1)</span>} pyramidal slips were further activated. Moreover, with an increase in pre-tension strain, there is a significant rise multiple slips probability within the α_p during torsional deformation. On contrary, for the secondary α (α_s) phase, the probability of {<span>(10overline{1 }1)</span>}_α twins formation during torsional deformation firstly rises and then reduces. These findings indicate that α phase, particularly α_p, plays a crucial role in accommodating deformation. This discovery offers valuable insights for further adjustments and optimizations of material microstructure and properties. Additionally, modifying external load can alter the stress state of components and enhance their fracture resistance during service, thereby broadening their range of applications and improving material reliability.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"29 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high specific surface of Zn powders leads to severe side reactions such as hydrogen evolution and corrosion, thus limiting their widespread use. Here, this work develops a novel CuO@Zn powder anode with a synergy effect of surface wrapping and compositing. Zn powders are uniformly wrapped by small CuO particles due to the strong adsorption between Zn and CuO. The wrapped CuO particles build a good conductive framework to inhibit the structural collapse of the Zn powder caused by corrosion and non-uniform deposition. Meanwhile, CuO can also be used as a seed to guide the uniform deposition of Zn ions through its strong binding energy with Zn. As a result, the CuO@Zn anode can maintain a long cyclic life of 900 h at current density of 1 mA·cm⁻² and capacity of 1 mAh·cm⁻², as well as contribute to an excellent capacity retention of 92% after 800 cycles for CuO@Zn||NH₄V₄O₁₀ full cell. Even at high current density of 5 A·g⁻¹, the full cell exhibits a specific capacity of more than 200 mAh·g⁻¹ after 800 cycles, with a good capacity retention of 89%.
