Liquid metals such as gallium and its alloys can be printed on various substrates to form electronic circuits. However, up to now there are still few methods for the direct writing of liquid metals on common printed paper. Here, a novel conductive material prepared by adding metal powder to a gallium alloy is introduced. The proposed material exhibits low liquidity, excellent plasticity, significantly enhanced adhesivity to paper substrates, which guarantee the stable and flexible electrical connection. The oxide film wrapping the nickel powder forms a skeleton for additional oxidation products, resulting in superior adhesion to paper. In addition, several paper flexible electronic applications are showcased to demonstrate the practical value and reparability of this material. This work paves the way for the design of a facile method of preparing paper electronics.

Polymer materials, commonly used and susceptible to damage from external forces and environmental factors, now have a new intelligent self-healing variant inspired by living organisms. This material self-repairs via dynamic covalent bonds and noncovalent interactions, mitigating microdamage risks and enhancing longevity. The self-healing polyurethane urea based on disulfide bonds was prepared by reacting a prepolymer synthesized from lipoic acid (TA), triethylenetramine (TETA), and polytetrahydrofuran (PTMEG) with isocyanate. Subsequently, nickel powder modified with amino groups on the surface was prepared by the hydrolysis of tetraethyl orthosilicate (TEOS) and modification with 3-aminopropyltriethoxysilane (APTES), and it was used as a magnetic and conductive filler added to the polyurethane urea to create magnetic self-healing polyurethane urea composites (MPUU-MNi). The material self-repaired at 40◦C for 12 h after damage, with a self-healing efficiency of 73%. The initial ultimate stress of MPUU-MNi-10 was 8.08 MPa, and after repair, the ultimate stress of MPUU-MNi-10 recovered to 5.89 MPa. It possesses good magnetic properties, mechanical properties, self-healing performance, and magnetic driving performance. Engineers can acquire knowledge about the most recent developments in electromagnetic shielding, which they can creatively integrate into their projects. Delving into cutting-edge materials and production methods could result in significant product innovation, enhancing their company's market edge.

The escalating issue of electromagnetic microwave pollution necessitates the development of high-efficiency absorbing materials. Composite materials featuring multiple loss mechanisms have emerged as the primary approach for creating effective electromagnetic wave absorbers. Among these, metal sulfides are promising candidates due to their unique properties and controllable microstructures. However, the wave absorption capabilities of single metal sulfides are inherently limited. To enhance their electromagnetic absorption properties, strategies such as morphological regulation and the doping of foreign materials have proven effective. In this study, we reacted nickel powder and iron powder with tin disulfide to synthesize binary metal sulfides. These sulfides were subsequently combined with graphite through ball milling to create a wave-absorbing material characterized by both dielectric and magnetic losses. The formation of suitable heterogeneous interfaces, diverse compositions, and abundant defects enables effective impedance matching and promotes multiple dielectric polarization, thereby synergistically enhancing electromagnetic wave (EMW) absorption capacity. Leveraging these advantages, the Fe-Sn-S binary metal sulfide demonstrates an effective absorption band at 4.46 GHz, achieving a minimum reflection loss ( RL min ) of −64.48 dB. This research paves the way for new composite materials designed for improved sulfide-based electromagnetic wave absorption.

The utilization of fly ash (FA) and the treatment of electromagnetic pollution have become important contents of current environmental management. A new type of electromagnetic waves absorption material was obtained by using fly ash magnetic beads (FAB), nickel powders (Ni) and polyaniline (PANI) in this study. A novel core–shell PANI@FAB/Ni composite was successfully prepared by interfacial polymerization of PANI on the surfaces of FAB and Ni. The structure, composition, morphology, magnetic property and electromagnetic parameters of composites were investigated in detail. Due to the synergistic effect of several different loss mechanisms, which improved attenuation capacity and impedance matching, the optimal reflection loss of PANI@FAB/Ni at 5.52 GHz was −67.07 dB (thickness of 5.48 mm). Meanwhile, the effective absorption bandwidth of PANI@FAB/Ni is 4.24 GHz with a thin matching thickness of 1.98 mm. This novel electromagnetic waves absorption material made of FAB has potential commercial prospects.

Single electron transfer living radical polymerization of methyl methacrylate catalyzed by the in situ prepared Cu(0) at ambient temperature was first examined using various metallic powders, including Zn(0), Ni(0), Mg(0), and Fe(0). Importantly, the polymerization initiated with Ni(0)/EBiB/CuBr 2 /PMDETA system exhibited optimal living/controlled nature and generated polymers with polydispersity index as low as 1.04 for 75.27% conversion and controlled molecular weights close to theoretical ones. A wide of range of Cu(II) salts were also investigated as catalyst sources instead of CuBr 2 . The recycling of Ni(0) was very convenient due to its magnetic property, which enables its extensive application. © 2013 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2013

Although cobalt nitride (CoN)-based nanomaterials have been widely designed as advanced oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR) catalysts, the continuous consumption of lithium-ion batteries (LIBs) has led to a high price of cobalt metal. Therefore, in the future, recycling valuable Co elements from spent devices and boosting their service efficiency will inevitably promote the utilization of Co-based materials in water splitting and zinc-air batteries (ZABs). Herein, we realize the Co recycling from spent LIBs by a simple hydrometallurgy method. Under the assistance of hexamethylenetetramine and polystyrene spheres, after the hydrothermal and pyrolysis treatment in the NH 3 atmosphere, the as-reclaimed cobalt oxalates were successfully transformed into novel three-dimensional (3D) CoN nanoflowers (denoted as CoN NFs). Benefiting from the unique 3D flower-like architectures, intrinsic high conductivity, large surface area, uniformly dispersed CoN nanoparticles, and the synergistic effect between Co 3 N and CoO phases, the 3D flower-like CoN NFs exhibited excellent OER catalytic activity. The performance was much better than commercial RuO 2 in the 1.0 M KOH solution. Furthermore, the CoN NFs-based water splitting cell needed a voltage of 1.608 V to achieve the current density of 10 mA cm −2 , which is even 16 mV smaller than that of Pt/C||RuO 2 benchmark (1.624 V). Meanwhile, the CoN NFs-derived ZAB exhibited a high peak power density of 107.3 mW cm −2 (vs. 103.2 mW cm −2 of Pt/C-RuO 2 -based ZAB) and a low charge–discharge voltage gap (0.93 V vs. 1.43 V of Pt/C-RuO 2 -based ZAB). Due to the excellent structural and elemental stabilities, the corresponding water splitting cell and ZAB had outstanding durability. This work successfully explored an advanced industrial chain from recycling Co metal in spent devices to designing the high-efficiency HER/OER/ORR electrocatalysts for advanced water splitting devices and ZABs. This will further promote the value-added utilization of valuable Co metal in various energy storage or conversion devices.

Molten-salt electrorefining (MSE) is currently the primary method for purifying many elements, offering promise for the sustainable upcycling of spent metals in the future. However, the conventional constant-current electrolysis protocol inevitably leads to deterioration of the microenvironment near the electrode, leading to reaction runaway and process inefficiency. In this work, we comprehensively studied for the first time the effect of constant- and pulse-electrolysis protocols on environmental evolution in electrode–electrolyte interfaces during the MSE of Ti, using a computer model. The results showed that compared to constant electrolysis, pulse-electrolysis protocols could effectively regulate the interfacial microenvironment and improve the electrorefining efficiency. Furthermore, a correlation between interfacial reconstruction and pulse parameters was established, indicating that the duty ratio was the key factor in inhibiting the deterioration of the interfacial microenvironment. To further verify the simulation results, the real-time morphological evolution of the electrodes during electrolysis was monitored by a novel in situ X-ray computed tomography (CT) technology under pulse-electrolysis protocols. The experimental results indicated that the pulse-electrolysis protocols enhanced the interfacial microenvironment and promoted electrolysis efficiency. Collectively, this work demonstrated that MSE could be effectively advanced by rationally designing the pulse-electrolysis protocols, facilitating its large-scale application in industry.

The development of highly efficient and stable electrocatalysts is crucial for the practical application of water splitting in renewable energy production. The Ni-Fe Phosphate electrocatalyst was synthesized through a simple and scalable electrodeposition method. This study presents a comprehensive investigation into the surface reconstruction engineering of an amorphous Ni-Fe phosphate electrocatalyst for enhancing its performance in alkaline water splitting. The reconstructed electrocatalyst exhibits significantly improved activity in alkaline water splitting. As expected, a low cell voltage of 1.86V was used to drive water splitting at 300 mA cm −2 , while the electrodes maintained high stability during 180 h continuous full water splitting at 70 mA cm −2 . This work provides insights into the mechanisms underlying the enhanced performance of the reconstructed Ni-Fe Phosphate based electrocatalyst and offers a promising approach for the design of advanced electrocatalysts for water splitting.

While high-entropy alloys, high-entropy oxides, and high-entropy hydroxides, are advanced as a novel frontier in electrocatalytic oxygen evolution, their inherent activity deficiency poses a major challenge. To achieve the unlimited goal to tailor the structure–activity relationship in multicomponent systems, entropy-driven composition engineering presents substantial potential, by fabricating high-entropy anion-regulated transition metal compounds as sophisticated oxygen evolution reaction electrocatalysts. Herein, a versatile 2D high-entropy metal phosphorus trisulfide is developed as a promising and adjustable platform. Leveraging the multiple electron couplings and d–p orbital hybridizations induced by the cocktail effect, the exceptional oxygen evolution catalytic activity is disclosed upon van der Waals material (MnFeCoNiZn)PS 3 , exhibiting an impressively low overpotential of 240 mV at a current density of 10 mA cm −2 , a minimal Tafel slope of 32 mV dec −1 , and negligible degradation under varying current densities for over 96 h. Density functional theory calculations further offer insights into the correlation between orbital hybridization and catalytic performance within high-entropy systems, underscoring the contribution of active phosphorus centers on the substrate to performance enhancements. Moreover, by achieving electron redistribution to optimize the electron coordination environment, this work presents an effective strategy for advanced catalysts in energy-related applications.

Developing a cost-effective and environmentally friendly process for the production of valuable chemicals from abundant herbal biomass receives great attentions in recent years. Herein, taking advantage of the “lignin first” strategy, corn straw is converted to valuable chemicals including lignin monomers, furfural and 5-methoxymethylfurfural via a two steps process. The key of this research lies in the development of a green and low-cost catalytic process utilizing magnetic Raney Ni catalyst and high boiling point ethylene glycol. The utilization of neat ethylene glycol as the sole slovent under atmospheric conditions obviates the need for additional additives, thereby facilitating the entire process to be conducted in glass flasks and rendering it highly convenient for scaling up. In the initial step, depolymerization of corn straw lignin resulted in a monomer yield of 18.1 wt%. Subsequently, in a dimethyl carbonate system, the carbohydrate component underwent complete conversion in a one-pot process, yielding furfural and 5-methoxymethylfurfural as the primary products with an impressive yield of 47.7 %.

In this study, we screened out the dominant spoilage microorganisms during the cold storage of morels, prepared composite paper with a targeted selection of antimicrobial active substances, applied the composite paper to morels for cold storage and preservation, and investigated the changes of physicochemical indexes, flavor-presenting nucleotides and enzyme activities throughout the process of storage, and evaluated the freshness preservation effect. The pathogenic microorganisms during the natural spoilage of Morels were isolated and purified at 4 °C. The dominant spoilage microorganisms obtained were: bacterium B1 ( Lelliia amnigena ), fungi F2 ( Paecilomyces penicillatus ) and F3 ( Mucor hiemalis ). Inhibition experiments were carried out by selecting various active antimicrobial agents—lemon essential oil, clove essential oil and nisin (NI)—against the dominant spoilage microorganisms B1, F2 and F3. Comparing the inhibitory effects, NI was selected as an inhibitor for the dominant spoilage microorganisms following comprehensive consideration. The antimicrobial system (NI/C-CNC) was prepared by incorporating NI into carboxylated cellulose nanocrystals (C-CNC), and it exhibited a strong blocking effect on ultraviolet rays, which became more pronounced with the increase of NI addition. The composite paper NI-C was prepared using the NI/C-CNC antimicrobial system and absorbent paper (100 % virgin wood pulp), which showed better mechanical properties and reduced water vapor transmission rate (WVP). NI-C composite paper was applied to the preservation of morels, which effectively inhibited the dominant pathogenic bacteria. The flavor 5′-nucleotides were effectively protected, and it significantly slowed down the change in hardness during storage of morels. It also inhibited lipid peroxidation, as evidenced by the accumulation of malondialdehyde (MAD) content and reactive oxygen species (ROS), and had a positive effect on the control of enzyme activity. NI-C antimicrobial composite paper has good application prospects in the field of packaging of morels.
