Regulating the artificial solid electrolyte interphase (SEI) and interfacial solvation structure of the electrolyte is crucial for developing rechargeable magnesium batteries (RMBs) with long cycling life, high current density tolerance, and fast ion transport capability operated under extreme environments, such as low temperatures. Herein, an effective strategy using oligomeric poly(3,4-dihydro-2H-pyran) (polyDHP) is proposed to modulate the interfacial solvation structure of RMBs, with the construction of an artificial SEI with rapid Mg-ion conductivity. The steric hindrance of polyDHP and its electrostatic interaction with Mg2+ reduce the solvent molecules in the first solvation shell, allowing polyDHP molecules to participate in coordination, thus lowering the desolvation energy barrier of Mg2+ and facilitating their deposition and stripping. Furthermore, due to the glass transition behavior, oligomeric polyDHP exhibits a more ordered structure with more continuous internal ion transport channels at −20 °C, therefore enabling stable RMB operation at lower temperatures for the first time. The corresponding Mg symmetric cells display a much lower overpotential (400 mV) and excellent cycling stability at both room temperature (over 5000 h at 5 mA cm–2 and 10 mA h cm–2) and a low temperature of −20 °C (over 1300 h at 3 mA cm–2 and 3 mA h cm–2). This strategy supports the stable cycling of CuS∥Mg full cells for over 200 cycles at −20 °C. This work reveals the importance of regulating the interfacial solvation structure, promoting the realistic applications of RMBs under extreme conditions.

Zinc-ion batteries, known for safety and efficiency, are a hotspot in electrochemical energy storage field. Nonetheless, the emergence of dendrites on zinc anodes during electrochemical cycles can lead to capacity attenuation and even failure, particularly under low temperatures. In this study, we develop a novel dendrite-free and low-temperature resistant Zn(ClO 4 ) 2 /Li 2 SO 4 /Dimethyl sulfoxide (DMSO) hybrid electrolyte by using DMSO as a hydrogen bond acceptor and solvation regulator. Our research demonstrates that, by reducing the desolvation energy barrier of the Zn 2+ solvation sheath and the nucleation overpotential of Zn deposition, DMSO effectively inhibits zinc dendrites and side reactions. Furthermore, DMSO disrupts hydrogen bonding between water molecules, preventing electrolyte freezing at low temperatures. As a result, at 0.5 mA cm −2 , the Zn||Zn symmetric device using this hybrid electrolyte exhibits consistent operation for over 4000 h even at -25 °C, featuring a minimal deposition/dissolution overpotential of approximately 0.045 mV. Additionally, at -20 °C, the Zn||Zn(ClO 4 ) 2 -Li 2 SO 4 -DMSO||LiFePO 4 battery demonstrates stable cycling for over 600 cycles at 0.6 C (1 C = 170 mA g − 1 ), delivering a capacity of 103 mA h g −1 .

The chromium-benzenedicarboxylate metal–organic framework (MOF), MIL-101(Cr), is one of the most well-investigated and widely used prototypical MOFs. Regarding its synthesis, the use of a toxic modulator (usually HF) and high reaction temperature (220 °C) are the main factors hindering its further expansion of production and utilization. In fact, high quality MIL-101(Cr) crystals can be prepared at a much lower temperature (160 °C) with spherical morphology via an additive-free approach. Compared to traditional octahedral MIL-101(Cr), the spherical MIL-101(Cr) possesses higher adsorption performance toward dye molecules, including methyl orange (MO) and rhodamine B (RB). The results suggest that toxic additives and high reaction temperatures are not essential in the synthesis of MIL-101(Cr), and the fabrication of spherical MIL-101(Cr) may offer a facile and effective pathway for the large-scale industrial application of MIL-101(Cr).

The combination of silicon carbide (SiC) ceramics and stereolithography technology has the potential to manufacture complex-shaped SiC components, thereby expanding application possibilities. However, the high sintering temperature and structural-performance anisotropy of three dimensional (3D)-printed SiC components have limited their practical use. Herein, a novel method is introduced to produce high-specific-strength SiC-based ceramics at a relatively low temperature of 1100 °C. To enhance ultra violet (UV) light penetration in the SiC slurry, a mixed SiC/SiO2 slurry (30% SiO2 and 70% SiC by volume) with a solid loading of up to 40% was prepared, improving printability. Additionally, a high methyl-phenyl-polysiloxane (PSO) solution content (75% of liquid resin weight) was incorporated to enable the low-temperature pyrolysis of SiC/SiO2/PSO ceramics. The resulting pyrolyzed SiC/SiO2/PSO lattice ceramic exhibited a high specific strength of 1.03 × 105 N·m/kg with a density of 1.75 g/cm3, outperforming other SiC-based lattice structures with similar porosity. The bending strength of SiC/SiO2/SiOC ceramics reached 95.49 ± 8.79 MPa, close to some of those prepared at temperatures of 1400 °C and above). Notably, the addition of the silicon carbide oxide (SiOC) phase to the SiC/SiO2 ceramics significantly reduces anisotropy, lowering the transverse and longitudinal compression strength ratios from 1.87 to 1.08, achieving 79% compensation in mechanical properties. This improvement is attributed to the cohesive force of SiOC shrinkage, promoting a uniform distribution of sintered components, resulting in a more robust and balanced material structure. This method offers valuable insight into the additive manufacturing (AM) of SiC-based ceramics at lower temperatures and provides new guidance for controlling anisotropy in 3D-printed ceramic parts.

The development of a highly efficient non-noble catalyst for rapid releasing of hydrogen from methanol/water at low temperature is urgent, but challenge. In this paper, the high content of graphited N-doped carbon encapsulated reducing state copper catalyst was fabricated for low-temperature aqueous reforming of methanol. The Cu@NGC-600 catalyst gives excellent hydrogen production rate of 46.15 μmol·g cat -1 ·s -1 at 190 °C, which is 4 times higher than the commercial 20 % Pt/C catalyst and 3 times higher than other reported Cu-based catalysts (such as the Cu@NC-200 catalyst). Characterization and DFT calculation results revealed that rich doping of graphite N and the synergistic effect of Cu–N strengthened the electron transfer between copper and the NC matrix, decrease the reduction temperature of catalyst, which enabled the Cu to maintain a highly reduced state of Cu 0 /Cu + during APRM for low temperature (150–190 °C) hydrogen production.

The ZnO–Al 2 O 3 –B 2 O 3 –SiO 2 (ZABS) glass powder was designed and innovatively employed to join AlN ceramics. The crystallization, thermal expansion and wettability behavior of the ZABS glass and glass-ceramic were investigated. The results shows that Zn 3 B 2 O 6 , ZnSiO 4 and Zn 4 B 6 O 13 were precipitated after heat treatments at different temperature, respectively, resulting in a variation in the coefficient of thermal expansion (CTE) of the ZABS glass ceramic. Then guided by the wetting behavior on the AlN ceramic substrate, the joining of the AlN ceramics by ZABS glass at various temperatures and holding times were conducted. Notably, Zn 3 B 2 O 6 was identified to be the primary product in the joints bonded at temperature of 700–800 °C due to the crystallization within the glass and no discernible reaction was observed between the substrate and the interlayer, while ZnSiO 4 was observed at the periphery of Zn 3 B 2 O 6 after 750 °C. Moreover, the crystalline phase Zn 3 B 2 O 6 gradually grew with the temperature and holding time increasing as the glassy phase gradually diminished, resulting in a reduction of the strength and reliability of the joints. The optimal flexural strength of the joints was 156 ± 11MPa at 700 °C for 30min. The reason for the high strength can be attributed to the interactions between the glass precipitated crystalline phase interlocking each other and the glass phase tightly bonded with the crystalline phase.

The directional rebound control of droplets is of great significance in many industrial applications, such as anti-icing, self-cleaning and microfluidics devices. Various strategies of droplets directional transport have been studied at room temperature and high temperature. However, it is still a challenge to control the rebound direction of droplets without external forces at low temperature and condensation conditions, where the droplets transit to Wenzel state. Herein, two kinds of graphene-based wrinkled superhydrophobic films with regular high-low structures (RSGF) and irregular spiral structures (ISGF) are prepared. The droplets on the films are still in the Cassie state by adjusting the size of the microstructure at low temperature. More importantly, the experimental and numerical simulation results reveal that the regularity of wrinkled structures can be used to adjust the distribution of viscous forces between film and droplets, which can control the direction of droplets rebound force. On the RSGF, the impacting droplets can retract symmetrically and rebound along the vertical direction; while on the ISGF, the droplets retract asymmetrically due to the irregular spiral microstructure and the rebound direction is shifted in the fixed direction.

In this paper, hole-free, carbon-based all-inorganic CsPbI 3 perovskite solar cells (PSCs) with the structure of F-doped SnO 2 (FTO)/ZnO/CsPbI 3 /C are fabricated at a low temperature for the first time. Excess CsBr is added into CsPbI 3 precursor solution to obtain stable black phase CsPbI 3 at a low temperature (120 °C). ZnO is prepared by a spin-coating method at 120 °C. And then the C electrode is prepared by a doctor-blade method at 120 °C. The effect of different layers of ZnO on the performance of solar cells is investigated. The champion power conversion efficiency (PCE) of the solar cell based on 3 layers of ZnO is 10.95%, with a short-circuit current ( J SC ) of 17.66 mA/cm 2 , an open-circuit voltage ( V OC ) of 0.91 V and a fill factor ( FF ) of 68%, which is the best performance for hole-free, carbon-based all-inorganic CsPbI 3 PSCs fabricated at a low temperature, compared with the other reported results. The encapsulated device remained 91% of the initial PCE after being stored in a glove box for 5 months. For further application in flexible solar cells, the solar cells with the structure of PET/Sn-doped In 2 O 3 (ITO)/ZnO/CsPbI 3 /C are fabricated under the best parameter conditions and the PCE of 8.70% is obtained.

In this study, an efficient green light-emitting CuInS 2 /ZnS core/shell quantum dots were synthesized using a low temperature (130 °C) hot injection methods combined with multi-layers ZnS coating strategy. S-OAm (S powder dissolved in oleylamine) was used as sulfur source instead of conventional dodecanethiol, which supplied high concentration of H 2 S at low temperature and led to explosive nucleation of CuInS 2 and hence high concentration small size of CIS cores. Meanwhile, this method could supply enough sulfur sources for the ZnS coating process , resulting in high quality ZnCuInS 2 alloyed interface and ZnS surface coating layers, which led to excellent lattice match between the CuInS 2 core and ZnS shells, and better surface passivation . As the consequence, a maximum photoluminescence quantum yields of ∼85% at peak wavelength of ∼530 nm has been achieved. Based on this, the light emitting diodes with a maximum luminance of 4450 cd m −2 , luminous efficiency of 3.52 cd A −1 and an external quantum efficiency of 1.44% has been obtained, which is the best result so far for the green emission light emitting diodes based on the CuInS 2 quantum dots.

SnO x films were prepared by sol-gel spin coating technology on glass substrates at low temperature. Through the optimization of the solution process, the quality of the film was effectively improved. And the effects of rotating speed, substrate pretreatment and precursor concentration and other parameters on the films were emphatically discussed. It is found that the formation of the impurity particles and holes can be reduced and the film roughness can be decreased by treating the substrate with plasma. Adding a low-speed spin coating process before high-speed spin coating can significantly reduce the roughness of film. The roughness of film decreases, and the edge shrinkage phenomenon of film is improved with the increasing spin-coating speed. The thickness of the film increases linearly with the solution concentration, but the high concentration of precursor is easy to lead to the cracks of films. Based on the optimized solution process, SnO x films with flat, smooth surface (Rq = 0.25 nm) and high transparency (visible light transmittance >90%) can be prepared at low temperature, which is expected to be used in devices based on transparent films.

In this paper, we systematically studied the effects of coronene as nucleation seeds for graphene synthesis at low temperatures by chemical vapor deposition. Naphthalene was used as a solid carbon source which is capable of producing graphene at temperatures down to 300 °C. The experimental results showed clear evidence that coronene seeds work as preferred nucleation sites, through which the nucleation density and graphene domain size could be modulated. The introduction of the seeds greatly improved the homogeneity of monolayer graphene by suppressing uncontrolled nucleation and multilayer growth of graphene domains. The obtained carrier mobility of graphene fabricated at 400 °C by the seed-assisted process reached ∼912 cm2 V−1 s−1, which is considerably higher than that of ∼300 cm2 V−1 s−1 measured on graphene prepared without seeding. Besides offering cost advantages for large scale application, the technique proposed in this study may find significant applications in graphene/copper hybrid interconnects and graphene based flexible electronics.

In this work, a methyl propionate (MP)/fluoroethylene carbonate (FEC)-based localized high concentration electrolyte with lithium difluoro(oxalato)borate (LiDFOB) as the additive is reported. The tuned solvation structure and the addition of LiDFOB enable fast desolvation process of Li + and good formation of cathode/electrolyte interphase. This optimized electrolyte shows good compatibility with both lithium cobaltate (LCO) cathode and lithium metal anode, enabling 4.5 V Li/LCO cell to cycle 300 cycles at 1C (180 mAh g −1 ) rate with 87.7 % capacity retention. Even at 10C high-rate cycling, around 75.0 % of initial capacity is also achieved. In addition, it possesses decent conductivity and viscosity at low temperature, demonstrating the great low-temperature performance. It enables the high-loading Li/LCO cell to deliver 136.9 mAh g −1 capacity at −70 °C, showing the great discharge performance and application potential at such low temperature. In addition, the cell with this electrolyte could even be cycled at −40 °C with 77.8 % capacity retention after 100 cycles. This work implements the high-voltage, high-rate and low-temperature functions of battery by choosing appropriate electrolyte component and tuning its formulation. This work provides an effective method for designing a multifunctional lithium battery electrolyte.
