A large number of toxic, flammable, and volatile organic solvents are used in the organic tape-casting process, which have significant adverse effects on both the natural environment and human health. This study reports an aqueous polymer–ceramic slurry suitable for tape casting using water as the solvent instead of traditional organic solvents. The effects of chemical additives (dispersant, binder, plasticizer, and defoamer) on the viscosity, stability, and bubble content of the water-based alumina ceramic slurry used for aqueous tape casting were investigated. The results showed that when the dispersant (ammonium polyacrylate) (PAA-NH 4 ) and defoaming agent (M15-01) contents were 1.5 and 0.1 wt%, respectively, and the ratio of binder (polyvinyl alcohol) (PVA) to plasticizer (glycerol) was 0.6, the surface of the green tape obtained by aqueous tape casting was the smoothest and flattest. Moreover, the alumina ceramic substrate of a size of 100 mm × 100 mm obtained by cutting and sintering the green tape exhibited dielectric constant, thermal conductivity, and breaking tenacity of 9.73, 23.16 W m −1 K −1 , and 4.34 MPa m 1/2 , respectively, making it an ideal candidate for high-power integrated circuits. This study not only addresses the environmental and health concerns associated with organic solvents but also presents a promising solution for developing advanced aqueous polymer–ceramic slurries.

Supercapacitors are essential to future energy systems, enabling efficient energy storage and management. Transition metal oxides are pivotal in advancing supercapacitor performance due to their redox activity and conductivity. Here, we synthesize a multi-element transition metal oxide composite (NiO-(NiFeCo)O) via a one-step hydrothermal method, forming self-assembled 3D rough nanorod networks. This architecture enhances ion transport, provides abundant active sites, and delivers a specific capacitance of 1414.54 F g −1 at 1 A g −1 , with 98.35 % capacitance retention after 3000 cycles. We further developed an asymmetric supercapacitor (ASC) using NiO-(NiFeCo)O as the positive electrode and rGO self-assembled on SiO 2 as the negative electrode. The ASC achieved a remarkable energy density of 66.0 Wh·kg −1 at 800 W kg −1 , alongside 88.46 % capacitance retention after 11,000 cycles. This design balances high energy/power density with exceptional stability, addressing critical challenges in next-generation energy storage. Our findings highlight the potential of NiO-(NiFeCo)O//SiO 2 /rGO ASCs for scalable, sustainable applications in advanced energy systems.

Understanding the interaction between laser beams and liquid droplets has significant implications for applications in microfluidics and optical manipulation. Laser beams have previously been reported to act as tractor beams to pull microscopic particles toward the light source or serve as a heating source when directed from above to induce lateral droplet motion via photothermal effects. However, it remains unknown whether a laser beam can move a droplet toward its source. In this study, we show that a laser beam can pull a dyed droplet on a superhydrophobic surface toward the light source through a sequence of photothermal effects. By directing a green laser beam near the bottom front of a dyed droplet, we observe that the droplet moves toward the light source in two distinct stages. Initially, the dyed droplet advances due to contact angle hysteresis and coalescence with condensation satellite droplets. Subsequently, the droplet motion is stimulated by iterative bubble bursting, coalescence, and relaxation, a combination of effects not reported earlier. We experimentally investigate this motion phenomenon and analyze the influence of laser power and focal point position on droplet motion, offering new insights into laser-induced droplet manipulation.

Hetero-interface engineering of biomass carbon foam offers great potential for the innovation of lightweight, broadband electromagnetic (EM) wave absorption and thermal insulation materials. In this work, micro/macro three-dimensional (3D) network biomass carbon foams decorated with elliptical and nanoparticle TiO 2 structures derived from eggplant were prepared through freeze-drying, carbonization, and heat treatment processes. The distinctive structure promotes impedance matching, along with the reflection and scattering of EM waves. Additionally, the elliptical and nanoparticle TiO 2 are evenly distributed on the surface of the layered carbon foam, forming numerous hetero-interfaces that strengthen the interfacial polarization. The results show that the QT-3 sample (at 900 °C) achieved a minimum reflection loss (RL min ) of −28.41 dB at a 3.1 mm thickness, along with a broad effective absorption bandwidth (EAB) of 6.5 GHz (from 11.5 to 18 GHz) at 2.0 mm, covering the entire Ku band. Furthermore, within the detection angle range of 0°–90°, the radar cross-section (RCS) is reduced by more than 10 dB m 2 . Furthermore, the infrared stealth performance has been validated: it maintains a surface color consistent with the surrounding environment. Moreover, the surface of the QT-3 sample leveled off at 31.1 °C (in 50 min) when heated on a 112 °C heating plate. Therefore, the cooperative relationship between TiO 2 and carbon foam achieves multifunctional performance, including excellent EM wave absorption, superior infrared stealth, and thermal insulation properties, paving the way for the application of advanced stealth materials in complex and harsh environments.

For the first time, the valorization of waste shells from the Siraitia grosvenorii industry involves their conversion into carbon dots (CDs) for the detection of deep eutectic solvents (DESs) concentrations through their fluorescence effect. The material composition of the fruit shells was first analyzed, revealing that lignin constitutes 29.8 % of their total mass. Then four types of DESs were prepared for the extraction of lignin from these shells; among them, choline chloride-lactic acid (ChCl-Lac) achieving the highest extraction rate of 92.49 %. The obtained lignin was characterized and subsequently used as a raw material to synthesize carbon dots possessing tunable fluorescent properties with a quantum yield of 5.73 %. Moreover, it was found that Fe 3 + could quench the fluorescence of the CDs, while the addition of certain DESs could restore the quenched fluorescence. The presence of DESs alone could also induce changes in fluorescence when interacting with the CDs. Based on this effect, a new system for the effective quantitation of the concentration of DESs in aqueous solutions using CDs was established, and DESs were used in several main steps and played multiple roles. This study provides not only a solution for the value-added utilization of solid waste from current fruit industry, but also a new approach for the concentration detection of DESs in aqueous solutions.

A label-free fiber-optic optofluidic biosensor integrated into microfluidic chip based on vernier effect is proposed for the specific and high-sensitivity detection of DNA molecules, which is made up of a Michelson interferometer (MI) and a Fabry Perot interferometer (FPI) in parallel. The MI is prepared by a single-hole dual-core micro-structured fiber (MOF) with a suspended core attached to the hole serving as the sensing arm, and used as the sensing element. A micropore is etched directly above the microchannel of MI as the fluid inlet by femtosecond laser processing, and integrated into the microfluidic chip for sample replacement. The detection volume is only nanoliters and the sample can be quickly replaced within seconds. The experimental findings indicate that the proposed optofluidic sensor shows a high refractive index (RI) sensitivity of −8791 nm/RIU and has an ultra-low detection limit of 7.45 × 10 −6 RIU within the range of 1.3328–1.3370. By immobilizing probe DNA (pDNA) molecules on the suspended core through surface functionalization, the optofluidic sensor enables label-free detection of 1 μM complementary DNA (cDNA) solution and shows excellent specificity. The proposed fiber optofluidic biosensor has great development prospects in ultra-low volume and high-sensitivity detection of biomolecules.

Photothermal synergistic catalysis significantly enhances the efficiency of photocatalytic CO2 reduction, offering a promising strategy for accelerated CO2 resource utilization. Herein, a series of CuxInyS photocatalysts were synthesized, exhibiting tunable band gap energy by varying the Cu/In/S atomic ratios for photothermocatalytic CO2 conversion to C2H4. The typical CuInS2 demonstrates a more negative conduction band, significantly enhancing electron reduction ability and facilitating the multi-electron reduction of CO2 to C2H4. Additionally, the high sulfur vacancy in CuInS2 generates additional active sites, enhances charge separation efficiency, and consequently improves catalytic activity. The generation rate of ethylene reaches 45.7 μmol·g-1·h-1 with the selectivity of 79.7%. This study provides a new avenue for producing ethylene in photothermal catalysis, as well as highlights the superiorities of CuInS2 catalyst.

Polycarbonate-acrylonitrile-butadiene-styrene (PC-ABS) has been treated with an aqueous solution of N -methylpyrrolidone (NMP) and ethanol (C 2 H 5 OH) under conditions that achieve a controlled level of polymer swelling. In addition, the micro-etching effect of alkaline potassium permanganate on PC-ABS was investigated using a low environmental impact binary micro-etching system. The effect of NaOH concentration, etching time, and temperature on surface roughness, morphology, wettability, and PC-ABS adhesion strength has been examined. The PC-ABS surface characteristics were analyzed using field emission scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform-infrared (FT-IR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The results have demonstrated that the surface morphology was altered after micro-etching, with an increase in surface roughness ( R a ) from 9.69 to 316 nm. In addition, the contact angle decreased from 92.2° to 30.1°, and the adhesion strength increased to 0.88 kN/m. The findings of this study have established an effective micro-etching process using alkaline potassium permanganate that enhances the wettability, surface roughness, and adhesion strength of the PC-ABS copolymer.

Freeze-drying is a promising method for drying gels, but it is considered incapable of preparing bulk inorganic oxide aerogels. Herein, using tert-butanol/water co-solvent as the freeze-drying solvent, large-size crack-free monolithic silica aerogels with different absolute ethyl alcohol to tetraethylorthosilicate molar ratios were successfully synthesized via a vacuum freeze-drying process. Superhydrophobicity was then obtained through an efficient chemical vapor deposition hydrophobic modification process. As the molar ratio increased from 8 to 16, the density, linear shrinkage, specific surface area (SSA), and mechanical properties decreased, while the thermal conductivity decreased first and then increased. The freeze-dried silica aerogels show the lowest density of 0.078 g/cm 3 , the lowest linear shrinkage of 4.6%, the highest SSA of 962 m 2 /g, the highest Young's modulus of 904.3 kPa, and a lowest thermal conductivity of 0.026 W/(m·K). Despite the formed fine ice crystals compressing the gel skeleton to some extent in the freeze-drying process, the developed mesoporous skeleton structure is basically preserved, which ensures excellent thermal insulation and mechanical performance. This study demonstrates that high-quality monolithic inorganic oxide aerogels can be effectively prepared by the freeze-drying method, which provides them with another efficient drying method independent of supercritical fluid drying and ambient pressure drying methods.

Photothermal superhydrophobic surfaces, as one of the most promising anti-icing strategies, often suffer from significant performance degradation, such as loss of hydrophobicity and lack of mechanical durability under actual icing conditions, as well as in special environments. Also, under mechanical loading, abrasion exposes the underlying material, which alters the wettability of the surface from hydrophobic to hydrophilic. Here, we prepared a robust photothermal superhydrophobic coating with excellent environmental durability. The amorphous coating acts as an armor structure to resist abrasion, preventing the inner photothermal superhydrophobic filler from being abraded by abrasives larger than the frame size. The results demonstrate excellent water resistance (WCA: 158.2°) and photothermal conversion (1 sun irradiation: surface temperature rises up to 76.6 °C), significant icing delay, and fast ice melting behavior. The anti/deicing behavior is derived from the stable superhydrophobic surface, the excellent photothermal conversion of GO, and the competitive effect of hydrogen bonding between the oxygen-containing functional groups at the edge of GO with water molecules, further improving the anti-icing performance. Furthermore, the reliability of the coating was verified by a comprehensive durability assessment, including resistance to abrasion, acid and alkaline environments, temperature, water impact, and corrosion. This work offers great potential for the fabrication of photothermal superhydrophobic surfaces that are low-cost, efficient, durable, and convenient for large-scale preparation.

Developing fast and convenient sensors for 2,6-dipicolinic acid (DPA) is of great importance for enhancing microbiological safety in food and healthcare, with significant implications for broader industrial applications. This work presents lanthanide metal-organic frameworks ([Ln(H 2 atiip) 2 (phen) 2 (H 2 O) 5 (MeOH)] n , Ln = Eu, Tb), named as CUST-865 and CUST-866. This is the first time that principal component analysis method is utilized to distinguish DPA. DPA molecules precisely replace the coordinated water molecules in the metal-organic framework, enabling the construction of an open ratiometric lanthanide fluorescent sensor. Furthermore, a novel “one-to-two” logic sensor with a single-input and dual-output configuration was developed. This system exhibits chameleon-like behavior, dynamically adapting its output signals in response to the input. Furthermore, smartphone platforms equipped with color recognizer applications enable detection of DPA. The detection limits for CUST-865 and CUST-866 were determined to be 0.19 μM and 1.15 μM in tap water, and 0.22 μM and 1.11 μM in milk powder.

S-scheme heterojunctions have garnered significant attention in the field of solar energy conversion, predominantly owing to their profound ability to facilitate charge carrier transfer and enhance photocatalytic activity. In this study, we introduce a novel hollow molybdenum dioxide containing oxygen vacancies@Nickel-Iron layered double hydroxide (MoO 2 -OV@NiFe-LDH) S-scheme heterostructure, designed to achieve effective charge separation and thereby enhance photothermal-photocatalytic performance. The photocatalytic hydrogen production efficiency under visible light is enhanced by a factor of 10.15 relative to pristine molybdenum dioxide (MoO 2 ). Additionally, the photocatalytic degradation efficiency for tetracycline is improved by 21.5 % compared to Nickel-Iron layered double hydroxide (NiFe-LDH). These enhancements are attributed to the S-scheme carrier transport pathways and a significant photothermal effect, as substantiated by diverse characterization tests and theoretical calculations. The S-scheme heterojunction promotes electron-hole separation, augments carrier transport, and enhances photo-oxidative reduction capabilities. This research presents an innovative approach for fabricating S-scheme heterojunctions with unique architectures that significantly improve photothermal and photocatalytic efficiencies.
