Current advancements in anti-icing coatings emphasize the integration of photothermal, electrothermal, and superhydrophobic features to significantly enhance de-icing efficiency. However, these multifaceted coatings often involve intricate preparation methods and costly materials, making them susceptible to damage and reduced durability. This research aims to overcome these challenges by combining active and passive anti-icing principles to achieve full-time efficient anti-icing. A novel strategy is devised to modify the wettability of epoxy resins by grafting a fluorinated oligomer using a curing agent bridging technique. By utilizing micron-sized Titanium Nitride (TiN) and nanosized Acetylene Black fillers within a fluorine-modified epoxy resin, applied through a simple spray technique, the resulting coating exhibits excellent photothermal, electrothermal, and superhydrophobic properties. Evaluations confirm the coating’s robust mechanical durability for extended operational use and its stabilized effectiveness in photothermal and electrothermal de-icing. Notably, this approach maintains electrical conductivity by eliminating the filler hydrophobic modification, also enhancing the mechanical performance of nanocarbon-based multifunctional anti-icing coatings. Moreover, it simplifies the manufacturing process, reduces cost of coating materials, and enables broad application across various substrate surfaces.

The decoration of noble-metal remains an effective and general strategy to rejuvenate “old” sensing materials for targeted gases. Herein, gold was loaded onto electrospun SnO 2 nanofibers by a simple impregnation route and the resulting hybrids were employed to detect nitric oxide (NO). XRD, TEM, XPS and elemental mapping corroborated that metallic Au clusters were successfully anchored on the fiber surface. Owing to the spill-over effect, these clusters supply additional active sites and chemisorbed oxygen. Gas-sensing measurements revealed that, even at a relatively low operating temperature, the Au-decorated SnO 2 nanofibers delivered a striking response of 37.3 toward 200 ppb NO, whereas negligible cross-responses were observed to typical interferents in exhaled breath. Moreover, the sensor exhibited excellent repeatability and long-term stability. These results demonstrate the remarkable potential of Au surface functionalization for boosting the NO-sensing performance of SnO 2 nanofibers.

Two-dimensional (2D) layered group-IV monochalcogenides with large surface-to-volume ratio and high surface activity make that their structural and optoelectronic properties are sensitive to air oxidation. Here, we report the utilization of oxidation-induced gradient doping to modulate electronic structures and optoelectronic properties of 2D group-IV monochalcogenides by using SnS nanoplates grown by physical vapor deposition as a model system. By a precise control of oxidation time and temperature, the structural transition from SnS to SnSO x could be driven by the layer-by-layer oxygen doping and intercalation. The resulting SnSO x with a graded narrowing bandgap exhibits the enhanced optical absorption and photocurrent, leading to the fabricated SnSO x photodetector with remarkable photoresponsivity and fast response speed (<64 μs) at a broadband spectrum range of 520–1550 nm. The peak responsivity (7294 A/W) and detectivity (9.54 × 10 9 Jones) of SnSO x device are at least two orders of magnitude larger than those of SnS photodetector. Moreover, its photodetection performance can be competed with state-of-the-art of 2D materials-based photodetectors. This work suggests that the air oxidation could be utilized as an efficient strategy to engineer the electronic and optical properties of SnS and other 2D group-IV monochalcogenides for the development of high-performance broadband photodetectors.

The poor wettability between the ceramic reinforcements and the metal matrix makes it difficult to realize the densification process of composites, which is severely detrimental to their mechanical properties. To improve the mechanical properties of Al matrix composites (AMCs) reinforced by β-Si3N4 whiskers (β-Si3N4w), we prepare TiN coating on the surface of β-Si3N4w via molten salt process, remarkably strengthening the interface bonding between Al matrix and β-Si3N4w. By optimizing the coating layer thickness, the bending strength of AMCs reinforced by TiN-coated β-Si3N4w reaches 439 MPa at 850°C, exhibiting remarkable enhancement relative to the composites without TiN coating (335MPa). Meanwhile, the interfacial test shows that TiN-coated β-Si3N4w is well bonded with the Al matrix, and no interfacial defects were detected. Moreover, the TiN coating with appropriate thickness can efficiently alleviate the agglomeration of β-Si3N4w, promote the densification of AMCs, and modify the Al/β-Si3N4w interface.

A novel method for sensitive determination of chloride anion at multilayer nano-silver modified indium-tin oxide (ITO) electrode has been developed. The multilayer films were fabricated via self-assembly/electrochemical-assembly methods, in which the 3-aminopropyltriethoxysilane (APTS) was used to modify ITO conducting glass, layer-by-layer (LBL) method was applied to prepare the multilayer films and poly (diallyldimethylammonium chloride) (PDDA) was employed as a bridging ligand. The resulting electrode (Ag/{PDDA/Ag} m /APTS/ITO) surface was characterized with SEM and UV–vis. The electrochemical behavior of Cl − at the Ag/{PDDA/Ag} m /APTS/ITO electrode was studied by cyclic voltammetry. The results indicated that the modified electrode exhibited substantial enhancement in electrochemical sensitivity for Cl − due to its large surface area and particular absorbability. The Ag/{PDDA/Ag} m /APTS/ITO electrode detected Cl − by voltammetry based on the oxidation of Ag/Cl − that generated from a specific reaction of chloride ions with nano-silver. After accumulation of 3 min for Cl − at Ag/{PDDA/Ag} m /APTS/ITO electrode, the peak height (Ag/Cl − ) increased linearly with the concentrations of Cl − in the range of 1.0 × 10 −8 –1.0 × 10 −6 mol L −1 . The detection limit was 5.2 × 10 −9 mol L −1 at 3 σ level. This modified electrode could be successfully applied in water samples with low cost and high sensitivity.

In situ Ti(C, N), ring phase, and multi-phase enhanced Ni204-based alloy coating were prepared by adding various Ti/C/TiN ratios particles. The effects of the reinforcement phase on the microstructure, microhardness , tribological property, and microstructure characteristics at the interface between the coating and substrate were investigated. The results show that the coatings with a 5:1 mass fraction ratio of TiN/C exhibits the highest microhardness , which is 3.78 times higher than that of the original Ni204 coating. While, the coating with 21:7:2 mass fraction ratio of TiN/Ti/C exhibits the lowest friction coefficient , which is 4.44 times smaller than that of the original Ni204 coating. The addition of Ti and C particles promotes the precipitation of ring phase and carbides , reduces ceramic agglomeration, alleviates the floating of ceramic particles, and improves the bonding strength of reinforcement phases. Owing to the good mutual solubility among Fe, Ni, and, Cr elements, the diffusion happened at the interface between the coating and substrate.

Porous tin-based films are electrodeposited on copper foils from a choline chloride/ethylene glycol based electrolyte containing SnCl 2 ·2H 2 O without any complexing agent or additive. Increasing the deposition time and voltage produces thicker films . The initially deposited Sn grains are relatively uniform with an average size of 200–300 nm and a kind of self-assembly distribution constructing an open and bicontinuous porous network. The architecture of these films possesses a double-layer structure, i.e. SnO 2 (superficial layer)/Sn–Cu alloy (bottom layer), which is revealed by X-ray diffractometer and X-ray photoelectron spectroscopy. The electrochemical performance of the porous tin-based films as anode for lithium-ion batteries is measured. Although the capacity fades gradually with repeated cycling, a reversible capacity of 300-350 mAh g −1 is maintained for more than 50 cycles, which suggests that the in situ formed Sn--Cu alloy could provide an interlocking interface between active materials and current collector. Therefore, the tin's shedding from the current collector can be restrained. Moreover, the inactive materials, such as the oxide in the superficial layer and the Cu in the bottom layer, could also act as buffers to relieve the induced volume expansion of Sn during the repeated lithiathion/delithiation process, thus giving the good cycle performances.

The urea oxidation reaction (UOR) has garnered significant attention as a promising alternative to the oxygen evolution reaction (OER) for water electrolysis, owing to its superior kinetic properties that enable enhanced hydrogen production efficiency. However, the practical deployment of UOR technology remains hindered by the persistent challenge of developing electrocatalysts that simultaneously achieve high activity, long-term operational stability, and cost-effectiveness. Herein, we report a facile, eco-friendly, one-step synthesis process to fabricate nickel–tin electrocatalyst (Ni–Sn) on Ni foam for catalyzing UOR via electrodeposition, using SnCl 2 ·2H 2 O and NiSO 4 ·6H 2 O as the Sn and Ni sources, respectively. Notably, the Ni–Sn electrocatalyst with a Ni/Sn ratio (90.39:8.61 at%) exhibits remarkable UOR activity, delivering a low potential of 1.493 V versus RHE to reach 10 mA·cm −2 , a small Tafel slope of 83.5 mV·dec −1 , and excellent stability with minimal decay after 100 h of continuous operation in alkaline urea electrolyte (1.0 M KOH + 0.33 M urea). The excellent activity of the Ni–Sn electrocatalyst for UOR benefits from the synergistic interaction between Ni and Sn, which modulates the electronic structure and accelerates charge transfer kinetics, thereby significantly enhancing reaction dynamics. Furthermore, the intrinsic superhydrophilicity of the Ni–Sn catalyst promotes efficient mass transport of reactants and products, contributing to its superior bifunctional catalytic performance for UOR.

The typical Haber technical process for industrial NH 3 production involves plenty of energy-consumption and large quantities of greenhouse gas emission . In contrast, electrochemical N 2 reduction proffers environment-friendly and energy-efficient avenues to synthesize NH 3 at mild conditions but demands efficient electrocatalysts for the N 2 reduction reaction (NRR). Herein we report for the first time that commercial indium-tin oxide glass (ITO/G) can be used as a catalyst electrode toward artificial N 2 fixation, as it demonstrates excellent selectivity at mild conditions. Such ITO/G delivers excellent NRR performance with a NH 3 yield of 1.06 × 10 −10 mol s −1 cm −2 and a faradaic efficiency of 6.17% at –0.40 V versus the reversible hydrogen electrode (RHE) in 0.5 M LiClO 4 . Furthermore, the ITO/G also possesses good electrochemical stability and durability. Finally, the possible reaction mechanism for the NRR on the ITO catalysts was explored using first-principles calculations.

Defect engineering provides a promising strategy for modulating the optoelectronic properties of metal halides for versatile photonic applications. However, precise control over defects in metal halides to achieve tunable photoluminescence remains a grand challenge. Herein, a simple yet precise defect engineering strategy based on synthesis-defect-luminescence modulation was proposed to develop Cs 2 SnCl 6 and Cs 2 SnCl 6 :Ln 3+ (Ln = Tb 3+ , Eu 3+ ) perovskite variants as tunable emitters via a combined computational-experimental approach. By controlling the ratio of tin vacancies (V Sn ) and chlorine vacancies (V Cl ), intrinsic Cs 2 SnCl 6 features a tunable emission color from blue to near-white and to yellow, along with a record-high yellow emission (photoluminescence quantum yield, PLQY: 28.76%) and anti-thermal quenching performance, which overcomes the limitation of inefficient and monochromatic emission in traditional Cs 2 SnCl 6 . Moreover, by facilitating more V Cl defects, Cs 2 SnCl 6 :Ln 3+ with stable Ln 3+ doping and remarkably enhanced Ln 3+ emission have been realized through charge-compensation effects. Furthermore, tunable emission from green to red could be realized via energy transfer (ET) from Tb 3+ to Eu 3+ . Finally, we explored potential applications in solid-state lighting and information anti-counterfeiting. Our study not only reveals the intrinsic relationship between defect formation and optical properties in metal halides, but also establishes a rational defect engineering pathway for tuning photophysical properties.

A kind of nanosized, spherical-like Sn-Ni alloy composite was synthesized by spray drying the ball-milled mixture of SnO 2 , NiO and Super P carbon to obtain the precursor, then the metal oxides were reduced by carbon at 900 °C for 2 hrs. The morphology of the sample shown by scanning electronic spectroscopy was spherical-like particle with a diameter below 200 nm. X-ray diffraction pattern shows that the sample contains the alloy phase of Ni 3 Sn 4 , Ni 2 Sn 2 and Ni 3 Sn, element phase of Ni and Sn, and compound phase SnO 2 . The charge/discharge test shows that the alloy shows a reversible capacity of 571.1mAh/g with capacity retention of 78.6% after 20 charge-discharge cycles. The improved performance was ascribed to the lower particle size, the higher contents of alloy phase, the binder styrene butadiene rubber to buffer the expansion of the alloy and the improved electric contact between active material and copper current collector.
