Zinc-ion batteries (ZIB) present great potential in energy storage due to low cost and high safety. However, the poor stability, dendrite growth, and narrow electrochemical window limit their practical application. Herein, we develop a new eutectic electrolyte consisting of ethylene glycol (EG) and ZnCl 2 for dendrite-free and long-lifespan ZIBs. The EG molecules participate in the Zn 2+ solvation via coordination and hydrogen-bond interactions. Optimizing the ZnCl 2 /EG molar ratio (1 : 4) can strengthen intermolecular interactions to form [ZnCl(EG)] + and [ZnCl(EG) 2 ] + cations. The dissociation–reduction of these complex cations enables the formation of a Cl-rich organic–inorganic hybrid solid electrolyte interphase film on a Zn anode, realizing highly reversible Zn plating/stripping with long-term stability of ≈3200 h. Furthermore, the polyaniline||Zn cell manifests decent cycling performance with ≈78 % capacity retention after 10 000 cycles, and the assembled pouch cell demonstrates high safety and stable capacity. This work opens an avenue for developing eutectic electrolytes for high-safety and practical ZIBs.

There is great interest in adsorptive separation of light olefins from alkanes with the same carbon number. However, previous investigations mainly focused on binary olefin/alkane mixtures or always produced mixed olefin from multiple components. Adsorptive separation of single-component olefins from mixtures containing multiple olefins is of practical importance but still a big challenge in industry. Present work provides an approach to the successive separation of C3H6 and C2H4 from a mixture of C2H4/C2H6/C3H6/C3H8 using tandem twin fixed beds filled with two well-regulated zeolites LTA. The adsorbents of Ni-5A and Ag/Cd-4A were post-synthesized via low transition-metal doping into zeolites LTA and employed to separate the C3H6 and C2H4 from the quaternary mixture. The Ni-5A attains a C3H6 uptake of 2.25 mmol/g and a C3H6/C2H4 Henry selectivity of 10.4, while the Ag/Cd-4A exhibits a C2H4 adsorption capacity of 3 mmol/g and a C2H4/C2H6 Henry selectivity of 1015.5. Furthermore, the molecule sieving of C2H4 is mainly determined by the micropore size of adsorbent, and the selective adsorption of C3H6 over C2H4 is largely attributed to the strong guest – host interactions with the metal sites. In addition, both the Ag/Cd-4A and Ni-5A adsorption beds can be well desorbed via CO2 purging. The DFT calculations reveal the molecular deformation of C2H4 and C3H6 during passing through the 8MR of Ag/Cd-4A and the competitive adsorption affinity of Ni-5A towards C3H6. The present process of tandem fixed beds coupled with well-regulated zeolite adsorbents provide an efficient strategy for the adsorptive separation of the mixtures of olefins and alkanes. © 2023 Elsevier B.V.

Persistent organic pollutants (POPs) pose significant environmental and health risks due to their stability, toxicity, and propensity for bioaccumulation. Traditional treatment methods often fall short in effectively degrading these pollutants, facing challenges such as high costs, low efficiency, and particularly inadequate mineralization rates. In this study, we employ Rhodamine B (RhB) to sensitize BiOCl, thereby significantly broadening its spectral absorption range. The RhB-sensitized BiOCl demonstrates remarkable photocatalytic activity under both visible light and natural sunlight, achieving rapid degradation and high mineralization of Bisphenol A (BPA). BPA degradation experiments were conducted under natural light across various seasons (from March to October), at different times of the day (from sunrise to sunset), and under diverse weather conditions (sunny, cloudy and rainy). The results confirmed the significant capability and universality of RhB-sensitized BiOCl in rapidly degrading BPA at varying concentrations under natural light conditions. The primary reactive oxygen species (ROS) involved in BPA degradation along with potential degradation pathways were identified under both visible light and real sunlight. Additionally, RhB-sensitized BiOCl exhibits high degradation efficiency for other POPs such as phenol, 4-chlorophenol, and 2,4-dichlorophenol, thus showcasing broad applicability in treating wastewater contaminated with POPs. This study indicates that dye-sensitized BiOCl offers a viable, sustainable, and efficient solution for the remediation of POPs under natural light conditions.

The development of systems for the deterministic transfer of two-dimensional (2D) materials have undoubtedly contributed to a great advance in the 2D materials research. In fact, they have made it possible to fabricate van der Waals heterostructures and 2D materials-based devices with complex architectures. Nonetheless, as far as we know, the amount of papers in the literature providing enough details to reproduce these systems by other research groups is very scarce in the literature. Moreover, these systems typically require the use of expensive optical and mechanical components hampering their applicability in research groups with low budget. Here we demonstrate how a deterministic placement system for 2D materials set up with full capabilities can be implemented under 900 € which can be easily implemented in low budget labs and educational labs.

Scale-up hydrogen production from natural seawater presents a promising avenue to address the escalating depletion of fossil fuel resources. However, direct seawater splitting (DSS) remains a formidable challenge, primarily due to the deficiency of efficient, stable, and cost-effective catalysts for the oxygen evolution reaction (OER). In this paper, we demonstrate the fabrication of a self-supported heterostructured nanoarray electrocatalyst, namely, NiTe/Ni 2 P, which exhibits exceptional performance and durability in the OER in alkaline seawater conditions. Remarkably, this innovative catalyst displays an overpotential of merely 312 mV to achieve a current density of 100 mA cm −2 . Moreover, the overall seawater splitting (OSS) process can be achieved at a cell voltage of 1.68 V while maintaining a high faradic efficiency (FE) of nearly 100 % for the OER, alongside exceptional stability exceeding 100 h of continuous testing. We have validated the presence of heterostructures and strong interactions between NiTe and Ni 2 P, as well as the Cl - repelling capability resulting from the incorporation of P, which induces a more negatively charged surface. These aforementioned factors are posited as the fundamental drivers behind the catalyst's extraordinary performance and steadfastness in the OER during DSS. Moreover, this strategic approach harbors tremendous potential for the systematic development of catalysts exhibiting exceptional OER performance within the realm of DSS.

A newly-developed high-pressure die-cast Al-1.5Fe-1Ni alloy with high thermal conductivity: Design, microstructure, and properties

In this study, a novel high-pressure die-cast Al-1.5Fe-1Ni alloy with high thermal conductivity was designed, and the relationship between its microstructure and properties was discussed. Firstly, based on the effect of alloying elements on the electrical resistivity of aluminum and phase diagrams, we designed Al-1.5Fe- x Ni ( x  = 0, 0.5, 1, and 1.5) ternary alloys and investigated the effect of Ni content on the microstructure and thermal conductivity. The phase in the Al-1.5Fe- x Ni alloy ( x  = 0.5, 1, and 1.5) transforms to the Al 9 NiFe phase at room temperature because of the solid transformation from Al 13 (Fe, Ni) 4 to Al 9 NiFe. When the Ni content is below 1 wt.%, the alloy has a hypoeutectic composition. When the Ni content increases to 1.5 wt.%, needle-like primary phases are formed. The eutectic of the Al-1.5Fe- x Ni alloy consists of a fibrous inner eutectic phase and a lamellar outer eutectic phase. The morphological transition of the eutectic Al 9 NiFe phase is attributed to the element Ni enrichment in the remaining liquid. Based on the property’s evolution, an Al-1.5Fe-1Ni die-cast alloy was prepared. The microstructure of the die-cast Al-1.5Fe-1Ni alloy from surface to center is heterogeneous, and the skin layers exhibit different patterns. The formation of these skin layers depends on the cooling rate. The die-cast alloy exhibits a high thermal conductivity of over 190 W m −1 K −1 and an elongation of over 15%. A new thermal conductivity model for die-cast alloys based on the microstructural characteristics reveals the crucially harmful effect of solute concentration in the matrix on the thermal conductivity of die-cast Al-1.5Fe-1Ni alloy. The skin layer has a minimal effect on thermal conductivity. Primary α-Al grains with low solute concentrations promote alloy deformation, leading to quite high elongation. The study will provide new insights into the microstructure evolution and the relationship between microstructure and properties of Al-Fe-

The development of high-accuracy technologies to distinguish the quite tiny concentration change of tumor markers between negative and positive is of vital significance for early screening and diagnosis of cancers, but is still a great challenge for the conventional biosensors because of their “gradual” detection mode. Herein, a unique “leap-type” responsive lanthanide MOF-based biosensor (designated as Tb-CeMOF-X) with defect-mediated redox-/photo-activities is developed for precisely identifying acid phosphatase (ACP), an early pathological marker of prostate cancer (PCa) in serum. The engineered Tb-CeMOF-X probe achieves a bursting switch-on luminescence at the critical concentration of ACP (9 U ⋅ L −1 ), while keeping silent below this threshold, undergoing a qualitative signal change from “zero” to “one” between negative and positive indicators and thus significantly improving the identification precision. Significantly, such “leap-type” response performance can be further edited and amplified by rational defect engineering in the crystal structure to improve the accessibility of active centers, consequently maximizing the detection sensitivity toward ACP in the complex biological media. This study proposes the first paradigm for the development of “leap-type” biosensors with ultra-sensitive differentiation capability between negative and positive, and provides a potentially valuable tool for early and accurate screening of PCa.

Na superionic conductor (NASICON) structured cathode materials with robust structural stability and large Na + diffusion channels have aroused great interest in sodium-ion batteries (SIBs). However, most of NASICON-type cathode materials exhibit redox reaction of no more than three electrons per formula, which strictly limits capacity and energy density. Herein, a series of NASICON-type Na 3+ x MnTi 1− x V x (PO 4 ) 3 cathode materials are designed, which demonstrate not only a multi-electron reaction but also high voltage platform. With five redox couples from V 5+/4+ (≈4.1 V), Mn 4+/3+ (≈4.0 V), Mn 3+/2+ (≈3.6 V), V 4+/3+ (≈3.4 V), and Ti 4+/3+ (≈2.1 V), the optimized material, Na 3.2 MnTi 0.8 V 0.2 (PO 4 ) 3 , realizes a reversible 3.2-electron redox reaction, enabling a high discharge capacity (172.5 mAh g −1 ) and an ultrahigh energy density (527.2 Wh kg −1 ). This work sheds light on the rational construction of NASICON-type cathode materials with multi-electron redox reaction for high-energy SIBs.
