Summary: This study demonstrates the sensitive and selective detection of ethylenediamine (EDA) using a rationally designed polyoxometalate-viologen complex. The complex shows a proportional response to EDA concentrations through chromic intensity or Raman signals, with a low detection limit of 0.1 ppb. It also exhibits high selectivity in the presence of other interfering compounds. The highly sensitive and selective response is attributed to the presence of viologen in the crystal lattice, which facilitates electron transfer to the polyoxometalate. This work introduces a novel concept for the design of highly sensitive and dual response polyoxometalate-based sensors.

Summary: In aqueous Zn-ion batteries (AZBs), the use of Zn metal as an anode has advantages of high energy density, inherent safety, and low cost. However, direct contact between electrolytes and Zn metal leads to corrosion and dendrite growth, compromising the calendar life and Coulombic efficiency (CE) of AZBs. A novel hydrophobic-zincophilic bifunctional layer (HZBL-Zn) is introduced on the Zn surface to provide hydrophobic and uniform pathways for zinc ions.

Summary: The trajectory of a chaotic dynamical system is sensitive to the initial condition, while its statistics normally do not have sensitive dependence on small disturbances. Such a kind of chaos is called normal-chaos. Recently, a new concept named ultra-chaos has been proposed for the first time. Unlike normal-chaos, the small disturbances lead to large deviation even in statistics for ultra-chaos.

Summary: The electrodialysis (ED) technology for waste acids recovery is popular due to its low cost, high efficiency, and lack of pollution. Anion exchange membranes (AEMs) play a significant role in determining the acid recovery efficiency of ED. This study investigates the impact of different side group structures on the performance of AEMs. The research demonstrates that modifying the microphase separation structure with strong hydrophobic side groups improves fixed charge density, prevents proton leakage, and enhances counterion transport, resulting in better acid recovery performance.

Summary: This study presents a highly active and durable Co/N co-doped carbon catalyst prepared by pyrolyzing a Co-doped zeolitic-imidazolate framework-8 (ZIF-8). The catalyst showed excellent oxygen reduction reaction performance and only experienced a small decrease in half-wave potential after 5,000 accelerated stress test cycles in an acidic solution. It also demonstrated satisfactory cathodic catalytic performance in a hydrogen/oxygen single proton exchange membrane (PEM) fuel cell and a Zn-air battery, achieving high power densities. X-ray absorption spectroscopy and high-angle annular dark field-scanning transmission electron microscopy analyses revealed that the Co in the catalyst existed as single atoms coordinated with N, forming Co-N moieties and leading to high catalytic performance.

Summary: Membrane electrode assemblies (MEAs) for proton exchange membrane fuel cell (PEMFC) applications need to endure fuel starvation caused by blockage in the flow field. Recent research has shown that the thickness/structure of the anode layer has a significant impact on anode durability. This study focuses on understanding the mechanism behind this improvement and evaluates the effects of anode layer thickness and spatial distribution of Ir within the anode layer. It is found that thin layers or placing Ir near the gas diffusion layer (GDL) interface result in the longest reversal time.

Summary: In this study, a simple method for fabricating a high-performance composite catalyst consisting of Pt-Co intermetallic nanoparticles (IMNs) and Co, N co-doped carbon (Co-N-C) is proposed. The composite catalyst exhibits excellent activity and stability towards oxygen reduction reactions (ORR) and methanol oxidation reactions (MOR), delivering outstanding mass activities of 1.96 and 2.92 A mg(Pt)(-1) respectively, due to the synergistic effect of Pt-Co IMNs and Co-N-C film. This research may offer a promising strategy to enhance the electrocatalytic performance of Pt-based catalysts.

Summary: In this paper, the authors use the forced Duffing equation to illustrate that the famous small denominator problems can be completely avoided by using a non-perturbative approach based on the homotopy analysis method (HAM) called the method of directly defining inverse mapping (MDDiM). This method provides a way to define the inverse operator of an undetermined linear operator, effectively avoiding small denominators and obtaining convergent series of multiple limit-cycles. The HAM-based MDDiM has broader applications in mathematics and can be used to tackle many open problems related to small denominators.

The cathode also exhibited significantly enhanced ORR activity, achieving a maximum power density of 0.72 W cm-2.

Summary: We report a high-performance catalyst consisting of ordered PtCoNi ternary nanoparticles anchored on N, Co, and Ni co-doped dodecahedral mesoporous carbon (DMC). The catalyst exhibits enhanced electrocatalytic activity towards oxygen reduction reaction due to the formation of PtCoNi intermetallic compounds and the dual active centers of Co-N and Ni-N coordination. The optimized sample Pt3Co0.7Ni0.3/DMC demonstrates excellent performance with mass activity and specific activity 7.33 and 6.19 times higher than commercial Pt/C, respectively. This study provides critical insights into constructing efficient catalysts using a ternary intermetallic strategy and synergetic effect between active components and support.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
