The appropriate multi-component strategies and ingenious microstructure design remain challenging for the development of multifunctional and high-performance electromagnetic wave absorbing materials. Here, magnetic Ni nanoparticles-anchored reduced graphene oxide (RGO)/Ti 3 C 2 T x MXene hybrids were successfully assembled on melamine foam (MF) via electrostatic self-assembly and hydrazine vapor reduction processes, achieving high-performance electromagnetic wave absorption and multifunctionality . Interestingly, the RGO/MXene/Ni-MF achieves high-performance microwave absorption with a minimum reflection loss value of − 61.3 dB and a maximum width effective absorption bandwidth (EAB) of 7.04 GHz. The superior electromagnetic wave absorption stems from a 3D dielectric/magnetic network with satisfactory impedance matching, dielectric/magnetic losses, interface/dipole polarization and multiple reflection scattering. Furthermore, the RGO/MXene/Ni-MF also revealed outstanding hydrophobicity , thermal insulation , infrared shielding and incombustibility. This work opens up novel prospects for developing lightweight, multifunctional microwave absorbers for practical applications.

Bioaerosol infections containing pathogenic viruses and bacteria have resulted in significant economic losses and posed a serious threat to public health, as evidenced by outbreaks of coronavirus disease and avian influenza. Consequently, the sampling and screening of bioaerosols are crucial for the prevention of bioaerosol-borne diseases. In this study, an ultrasensitive biosensor based on zeolitic imidazolate framework-8-melamine foam (ZIF-8-MF) was innovatively developed for the specific capture and in situ detection of bioaerosols. The bacterial bioaerosols were collected by a wet cyclone into phosphate-buffered saline (PBS) buffer at a high collection rate, achieving a satisfactory collection efficiency of ∼80% within 10 min. The target bacteria collected in the PBS buffer were specifically captured and effectively concentrated using immune ZIF-8-MF. The gold@platinum nanozymes (GPNs) were employed to specifically label the captured target bacteria and efficiently amplify the biological signal. And the resulting colorimetric signal was analyzed via a self-developed smartphone application (App). This biosensor demonstrated the capability to detect bioaerosols containing Salmonella typhimurium in the range of 1.6 × 102–1.6 × 105 CFU/m3 within 1.5 h, with a detection limit as low as 100 CFU/m3. Compared with other bioaerosol detection methods, the biosensor offered advantages such as high collection rate, specific capture, efficient concentration, and in situ detection, positioning it as a highly promising and practical tool for the monitoring of bioaerosols containing diverse pathogenic bacteria.

In recent years, oil spills and organic pollution have caused severe damage to the ecological environment. Therefore, the treatment of oily wastewater has become a serious challenge. Here, with the help of melamine foams as a substrate, MXene nano-rough structures were built, and cetyltrimethoxysilane was grafted onto their surfaces to create an oil-absorbing material that is both user-friendly and effective at oil-water separation. Due to the nano structures of MXene were constructed and the long-chain silanes were modified on the foam surface, the material became superhydrophobic. In addition to being able to selectively absorb oils from an oil/water mixture (including emulsified oils) up to 111 times its weight, the modified foam was found to have a water contact angle of 157 which could selectively absorb oil but not water. Furthermore, it demonstrated sustained hydrophobicity and lipophilicity after experiencing strong acid/alkali or prolonged high-temperature treatment, allowing for various scenarios where oil-water separation can be used in severe settings without compromising performance.

Phase change materials (PCMs) demonstrate significant advantages in thermal energy storage and management systems due to their high enthalpy and almost constant phase transition temperatures. However, challenges such as inherent low thermal conductivity, flammability and leakage have limited their broad application. To address these issues, a biomimetic structural phase change composite (PEG/MF/PR) inspired by tomato was developed. This composite employed a melamine foam (MF) skeleton impregnated with phenolic resin (PR) followed by curing, which vacuum-adsorbed polyethylene glycol (PEG). In this biomimetic design, the MF functioned as columellar and vascular bundles, providing skeletal support; and the cured PR corresponded to flesh, enhancing mechanical strength of skeletal scaffold while providing abundant binding sites, thereby enabling the efficient encapsulation of PEG analogous to gelatinous substance. The obtained skeletal scaffold demonstrated a high PEG adsorption rate consistently above 84.5 wt%, along with superior leakage-proof feature. The PEG/MF/PR achieved an exceptional heat enthalpy of 159.2 J/g with a relative enthalpy efficiency of 97.1%, and exhibited outstanding thermal storage stability after undergoing 100 heating-cooling cycles. Thermal conductivity of PEG/MF/PR was approximately 0.1789 W·m −1 ·K −1 , representing a 41.4% enhancement compared to that of PEG/MF. More importantly, photothermal conversion capability of PEG/MF/PR was significantly enhanced due to the conjugated structures formed during PR curing and color darkening. The inherent flammability and dripping tendency of PEG upon exposure to flame were successfully mitigated by flame-retardant skeletal scaffold. Thus, the developed phase change composite provides great potential in waste-heat recovery and thermal management.

Phase change materials (PCMs) absorb and release energy from the environment effectively during the phase change process, leading to their widespread use in the field of thermal energy storage. However, the development of PCMs has been limited by issues such as poor thermal conductivity and light absorption. We therefore designed a silver-plated melamine foam (MF) framework and synthesized a phenolamine aggregate coating on the MF through a redox reaction, enhancing the bonding with silver nanoparticles and resulting in fully silver-plated MF. Meanwhile, hydroxylated carbon nanotubes (HCNTs) were added to the framework as a filler. This modification improved the conductivity of the corresponding polyethylene glycol (PEG)-based composite PCMs from 0.33 (pure PEG) to 0.82 W m⁻¹ K⁻¹ due to the construction of a multilevel thermal conduction channel. Additionally, a high photothermal conversion efficiency of 92.4 % was achieved through the combined effect of the local resonance absorption of the silver and the molecular thermal vibration of the HCNTs. These advances provide a new strategy for optimizing the performance of PCMs, with potential applications in energy storage and thermal management.

Phase change material (PCM) based passive cooling techniques are attractive candidates for thermal management of lithium-ion batteries due to the merits of low energy consumption and low cost. However, the commonly used solid-liquid PCMs suffer from leakage and poor thermal conductivity , limiting their wide applications. Herein, we report a novel composite PCM (CPCM) with melamine foam (MF) as the supporting matric, lauric acid as the PCM, and aluminum nitride (AlN) as the thermal conductivity enhancer. The CPCM presents a good anti-leakage feature, and AlN increases the thermal conductivity of the CPCM by 54.17% with a mass fraction of 15%. As a result, the CPCM with 15% AlN shows the best thermal management performance that the maximum battery surface temperature and the temperature difference can be decreased by 24.96% and 83.97% at a 3 C discharging rate compared to those without CPCM. Further, the maximum battery surface temperature is within 47.74 °C, and the temperature difference is no more than 0.34 °C under the cycling discharge-charge tests. The findings of the present work open up new opportunities to develop high-performance and reliable CPCMs for the thermal control of lithium-ion batteries, especially at high discharging rates.

Phase change materials (PCMs) can effectively absorb and release energy from the environment during the phase transition process. However, liquid phase leakage and poor energy storage occur easily at the same stage. Considering the good adhesion of polydopamine (PDA) and the high solar absorption properties of PDA and MXene , a new supporting material was prepared in this work by combining melamine foam (MF) and MXene under the action of PDA, which was used to encapsulate polyethylene glycol (PEG) to prepare a composite PCM (CPCM). Then, we experimentally studied the thermal properties of this new material. The results show that the proposed PEG/MPMF CPCM (PEG@MPMF) exhibits good heat storage properties, and the melting enthalpy reaches 186.2 J/g, which is 99.5% of that of pure PEG. The light absorption of PEG@MPMF is improved by the conjugate action of PDA and MXene. Additionally, this CPCM maintains excellent shape stability and reusability after 100 thermal cycles. Therefore, the PEG@MPMF shows great advantages in terms of heat storage and thermal management.

Endogenous glycopeptides are significantly important in diverse pathological and physiological systems, but their direct analysis is severely hampered by their low abundance and presence of interfering species in biological fluids. In this study, we synthesized the amine-functionalized titanium metal-organic framework (NH 2 -MIL-125(Ti)) by a simple hydrothermal method, characterized and used for glycopeptides enrichment. The designed separation media is highly hydrophilic and stable which is suitable for hydrophilic interaction chromatography (HILIC). To make the process smooth, simple, reliable, and robust, NH 2 -MIL-125(Ti) crystals were packed in pipette-tip using hydrophilic melamine foam, as supporting frit. Free amine groups, present in the structure imparted hydrophilicity and a unique pattern of porosity, contributing to the size exclusion effect that excluded the large-sized proteins up to 1:700 peptide to protein ratio. The prepared MOF particles possessed regular porosity, high surface area, good hydrophilicity, and offered an in-tip flow-based set-up enhanced the enrichment performance for N -linked glycopeptides. The affinity material showed a detection limit of 1 fmol.µL −1 and selectivity up to 1:1000 (HRP digest to BSA digest). Moreover, repeatability and reusability were evaluated up to five rounds of enrichment using the same affinity tip, and scanning electron microscopic images revealed no structural changes in the MOF crystals. Finally, the MOF packed in pipette tip was applied to selectively capture the N- linked endogenous glycopeptides from a healthy saliva sample and 64 unique endogenous glycopeptides were identified. These results demonstrated the excellent potential of NH 2 -MIL-125(Ti) based affinity tip for glycopeptides which can be used to enrich trace glycopeptide biomarkers from the biological fluids.

The construction of hydrophobic porous adsorption materials, which are cost-effective, green, stable, and efficient, are urgently demanded for the large-scale and effective oily wastewater treatment. Herein, a facile and low-cost two-step fabrication strategy of hydrophobic melamine foam (MF) was demonstrated, including cellulose acetate (CA) decoration and siloxane modification. Cellulose acetate initially assembled on the skeleton of MF with the aid of hydrogen bond formation between the hydroxyl groups of CA and imimo groups of MF. At an optimal concentration of CA, the as-prepared composite foam (CA/MF) exhibited good hydrophobicity. To further improve the oil/water selectivity, the above foam was enhanced by chemical vapor deposition (CVD) of methyltrimethoxysilane (MTMS). The successful silicification reaction between CA/MF and MTMS decreased the surface energy and improved the surface topological structure, leading to excellent hydrophobicity (water contact angle of 147.4°) and superoliophilicty. Such hydrophobized cellulose acetate/melamine foam (H-CA/MF) presented low density, favorable porosity (97.78%), and distinguished pore volume (88.66 mL/g), leading to a high oil adsorption capacity of up to 56.6 g/g. Due to the excellent mechanical elasticity of H-CA/MF, the oil absorption and recovery can be achieved easily by a simple manual adsorption-squeezing method and lab-made pump-assisted separation device with satisfactory recyclability. Moreover, H-CA/MF displayed marvelous stability and environmental adaptability in different harsh environment, further enlarging its practical application scenarios. Along with the green and cost-effective preparation process, the present study provides a facile strategy to fabricate hydrophobized melamine-based foam, which is of great significance for scalable and efficient oil/water separation.

The use of nano-catalysts to reduce nitroaromatic compounds is a promising wastewater treatment strategy. In this study, melamine foam (MF) is employed as the substrate, and sheet-like bismuth oxide iodide (BiOI) was grown on its surface through a cross-impregnation process involving Bi(NO3)3 and KI solution. As a catalyst, bismuth oxide iodide/melamine foam composite (BiOI/MF) exhibits remarkable catalytic activity and excellent durability in the treatment of continuous flow 4-nitrophenol (4-NP) solutions. The loading capacity of BiOI on a 2 × 2 × 2 cm3 MF substrate is notably low at just 0.13 g, yet it can completely reduce 50 mL 4-NP solution (0.37 mmol L−1) within 32 minutes. After six consecutive cycles, the catalyst maintained a conversion efficiency of over 90%, with the total treatment amount for 4-NP reaching 1.49 × 10−2 mmol. Furthermore, BiOI/MF also exhibited high catalytic reduction activity towards other organic pollutants, such as methylene blue and methyl orange solutions. In this study, we propose an efficient and cost-effective composite catalyst that offers technical guidance for the practical treatment of wastewater and sewage.

Interfacial solar vaporization has emerged as a promising technology for freshwater generation, attracting significant attention in recent years. Hydrogels, with their inherent hydrophilicity and low enthalpy of evaporation, are considered ideal materials for interfacial solar-driven evaporation. However, their practical deployment remains hindered by complex fabrication processes and high costs. Herein, we report the development of facile, low-cost hydrogel/melamine foam composite evaporators (HMFs) that enable highly efficient and stable interfacial solar vaporization. The HMFs were fabricated by spray-coating the carbon black-infused hydrogel onto the upper surface of the MF. Under 1.0 sun, HMFs achieved an evaporation rate of 2.51 kg·m⁻ 2 ·h⁻ 1 with an evaporation efficiency of 89.5 %. Notably, the HMF exhibited robust stability and durability under harsh environmental conditions, maintaining its structural integrity and steady evaporation performance even after 30 days of continuous outdoor operation. Furthermore, the spent HMFs can be recycled, and the SA-CB hydrogel would not cause pollution even if left in the environment. These findings establish HMFs as a highly competitive candidate for scalable and sustainable solar-driven freshwater production.
