Adhesives are crucial both in nature and in diversified artificial fields, and developing environment-friendly adhesives with economic procedures remains a great challenge. We report that folic acid-based coacervates can be a new category of excellent adhesives for all kinds of surfaces with long-lasting adhesiveness. Aided by the electrostatic interaction between the π–π stacked folic acid quartets and polycations, the resultant coacervates are able to interact with diversified substrates via a polyvalent hydrogen bond, coordination, and electrostatic interactions. The adhesivity to wood is superior to the strong commercial glues, but without releasing any toxic components. Upon evaporating water, the coacervate can be casted into a non-adhesive flexible self-supporting film, which restores the adhesive coacervate immediately on contacting water with original adhesive ability. In this way, the coacervate can be facilely tailored into a double-sided tape (DST), which is convenient for storage and application under ambient conditions. Given its excellent adhesive performance, release of nontoxic gases, and convenience in storage and application, the folic acid-based DST is very promising as a new adhesive material.

Nanoparticles with high surface energy and chemical activity have drawn substantial attention in petroleum industry. Recently, Janus nanoparticles exhibited tremendous potential in enhanced oil recovery (EOR) due to their asymmetric structures and properties. In this study, a series of amphiphilic pseudo-Janus@OTAB (PJ@C18) nanoparticles with different concentrations of stearyltrimethylammoium bromide (OTAB) were successfully fabricated. The structures and properties of PJ@C18 were characterized by Fourier transform infrared spectroscopy and ζ-potential measurements. Based on the emulsification experimental results, the interaction models and the self-assembly behavior between hydrophilic nanoparticles (SiO 2 @NH 2 ) and OTAB molecules at the oil/water interface were proposed, which was further confirmed via the measurements of the contact angle and dynamic interfacial tension. Interestingly, it was found that the change of pH value from 7.5 to 4.0 caused the type reversal of the PJ@C18-1000 stabilized Pickering emulsions. Furthermore, the PJ@C18-1000 stabilized Pickering emulsion system with excellent salt and temperature tolerances (10000 mg·L −1 , 90 °C) significantly improved the oil recovery in the single-tube (more than 17%) and double-tube (more than 25%) sand pack model flooding tests. The findings of this study could help to better understand the construction mechanism of pseudo-Janus silica/surfactant assembly and the potential application of PJ@C18-1000 stabilized Pickering emulsions for EOR.

TiO 2 spherical shells with both inner and outer surface modified by graphene have been successfully constructed through a stepwise loading method. This double-sided modification method greatly increases the contact area of the shell with graphene sheets, which is beneficial for graphene to separate more photoelectrons from both the inner and outer sides of the shell simultaneously. The results of photocatalytic reduction of CO 2 into CO indicate that the modification effects of inner and outer wall of TiO 2 shell by graphene seem to be relatively independent to each other. As a result, compared with the traditional single-sided modified samples, even these optimal ones, the loading of graphene on the other side of TiO 2 shell can still improve the photocatalytic reduction performance. Moreover, the optimal dosage of graphene on one side of shell surface is always maintained, without being affected by the graphene usage on the other side. This work indicates that the unique heterojunction obtained by graphene double-sided modification is advantageous to enhance the photocatalytic CO 2 reduction performance and expected to be extended to the construction of other photocatalysts.

Background In recent years, Supported catalytic packings (SCPs) with zeolite coating on metallic substrates have received extensive attention due to their satisfactory heat/mass transfer properties. Methods Herein, high-performance SCP with HZSM-5 coating was fabricated by secondary growth method with polydopamine (PDA)-assisted seeding, where PDA was used as a "double-sided adhesive" sandwiched between supports and seeds. The atom-economic reaction of cyclohexene and acetic acid for cyclohexyl acetate production was carried out to evaluate the catalytic performance of as-fabricated SCPs. Significant Findings Due to the strong adhesion of PDA, the uniform and high-coverage seeding layer was achieved under the optimized seeding conditions, then continuous HZSM-5 coating that possessed high crystallinity, rough surface, and intergranular voids was formed. Compared with SCP prepared by secondary growth method with the traditional dip coating seeding method, the catalytic activity and stable operation time of PDA-assisted SCP were increased by 50% and 57%, respectively. Furthermore, PDA-assisted seeding method is easy to conduct, indicating its great potential in practical applications.

Immobilizing the photocatalyst on solid substrates is considered a state-of-the-art technical requirement, which can address the separation problem for the reuse of nano photocatalytic materials. Graphite-like carbon nitride (g-C 3 N 4 ) shows excellent properties as an unconventional photocatalyst, but the surface with inert functional groups makes it difficult to produce strong adhesion to the substrate surface. Herein, nano g-C 3 N 4 was fixed on the transparent substrate with double-sided adhesive tape (DSAT), forming an uncomplicated and stable photocatalytic reaction platform for organic wastewater treatment. g-C 3 N 4 film is located at the outer bottom side of the platform, which can avoid the shading effect of sewage turbidity on the photocatalyst. Furthermore, the substrate and DSAT are transparent, thus the influence on the light absorption of g-C 3 N 4 can be negligible. The prepared g-C 3 N 4 film (520 nm) consists of one layer of the dispersed g-C 3 N 4 particles (590 nm). At low catalyst dosage (62.5 ppm), the absorption of g-C 3 N 4 film exceeds 90 % in 200–800 nm. The normalized photocatalytic degradation rate constant of the suspended g-C 3 N 4 and g-C 3 N 4 film are 0.280 h −1 and 0.423 h −1 for 80 mL Rhodamine B solution (10 mg/L), respectively. When the rotation speed increased from 0 RPM to 250 RPM, the rate constant could increase 3 times from 0.139 h −1 to 0.608 h −1 . Besides, the film's photocatalytic activity could be retained after 20 times of reuse, which shows the film has good recyclability. Compared with the suspended g-C 3 N 4 , the prepared film has obvious advantages in light absorption utilization, the photocatalytic performance and recovery.

While harvesting water from the atmosphere is considered as a promising technology to address the increasing issue of water scarcity, its wide applications are still limited by the difficulty in mass production of water harvesting materials. Here, an industrial-producible asymmetric wettability patterned fabric (AWPF) with high water harvesting capacity is developed using a continuous and low-cost weaving technology. Four textile patterns are developed for high-efficiency atmospheric water harvesting. The alternating patterned surface in AWPF is constructed with hydrophilic bumps and hydrophobic grooves using one set of green fluorine-free superhydrophobic polyester warp yarns and two sets of superhydrophobic polyester/hydrophilic viscose weft yarns. We optimized the water collection performance of the single-sided AWPF by spraying co-MBAA-DVB superhydrophobic material on the back of the AWPF to construct a wetting gradient, that is, double-sided AWPF. The double-sided AWPF shows a strong water harvesting capacity of 2840.2 mg·6h −1 ·cm −2 , which increased the water harvesting efficiency by 43.2 % compared with the unoptimized single-sided AWPF. To reduce the pressure drop, 6 mm wide the double-sided AWPF was designed, resulting in a water harvesting capacity that is 1.23 times higher than that of without cutting. This advanced industrialized weaving technology with an asymmetric fabric structure design holds great potential for substantial water harvesting.

To overcome the issues of difficult dispersion and recovery of powdered photocatalytic catalysts and secondary pollution, a double-sided adhesive loaded with TiO2/g-C3N4 photocatalytic material was prepared by a brushing method. The photocatalytic double-sided adhesive (PDSA) was analyzed by scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS), contact angle analysis, ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS) and fluorescence spectroscopy (PL). The degradation of Rhodamine B (RhB) was used to evaluate the photocatalytic performance of the PDSA. The best degradation of 96.96% after 2 h illumination and ultrasound treatment was achieved when the conditions were 10 mg L−1 RhB solution, 10 mL, 25 °C and pH = 7. Quenching agent experiments determined that ˙O2− and ˙OH were the main active species. The effect of impurity ions and soaking in acidic/alkaline solution on PDSA degradation was evaluated. After 5 cycles of degradation experiments, the degradation efficiency of PDSA was still up to 96.55%. This study provides a new solution for the loading of powdered photocatalysts.

Practical applications of lithium–sulfur batteries are simultaneously hindered by two serious problems occurring separately in both electrodes, namely, the shuttle effects of lithium polysulfides and the uncontrollable growth of lithium dendrites. Herein, to explore a facile integrated approach to tackle both problems as well as guarantee the efficient charge transfer, we used two-dimension hexagonal VS2 flakes as the building blocks to assemble nanotowers on the separators, forming a symmetrical double-side-modified polypropylene separator without blocking the membrane pores. Benefiting from the “sulfiphilic” and “lithiophilic” properties, high interfacial electronic conductivity, and the unique hexagonal tower-form nanostructure, the D-HVS@PP separator not only guarantees the effective suppression of the lithium polysulfide shuttle and the rapid ion/electron transfer but also realizes uniform and stable lithium nucleation and growth during cycling. Hence, just at the expense of an 11% increase in the separator weight (0.14 mg cm–2), the D-HVS@PP separator delivers an over 16 times higher initial areal capacity (8.3 mAh cm–2) than a conventional PP separator (0.5 mAh cm–2) under high sulfur-loading conditions (9.24 mg cm–2). Even when used under a low electrolyte/sulfur ratio of 4 mL g–1 and a practically relevant N/P ratio of 1.7, the D-HVS@PP separator still enabled stable cycling with a high cell-level gravimetric energy density. The potentials in broader applications (Li–S pouch battery and Li–LiFePO4 battery) and the promising commercial prospect (large-scale production and recyclability) of the developed separator are also demonstrated.

The scarcity of fresh water resources poses a significant challenge to humanity; therefore, it is necessary to advance the development of a sustainable and highly efficient evaporator. However, the light absorption capability of traditional evaporators is limited to only the top layer, and the single-sided absorption characteristics impose constraints on their efficiency. Herein, we propose a novel method for manufacturing double-sided light absorption evaporators, which mainly includes porous carbon/ceramic nanofilm and graphene upper and lower films as the light absorption layer of the photothermal conversion evaporator, and then the hydrophilic film interlayer transfers water upward. The transmission rate of seawater is affected by the tilt angle at which the evaporator is inserted; therefore, identifying the optimal working angle becomes crucial. Under conditions of inclination angle (15–75°), the evaporation rate of the evaporator with the optimum tilt angle reaches 3.15 kg m–2 h–1. The results of outdoor experiments demonstrate that the double-sided evaporator exhibits an evaporation rate 0.7 kg m–2 h–1 higher than that of the single-sided during noon hours. Furthermore, we simulate the evaporation efficiency of outdoor sunlight at different tilt angles through COMSOL. The design of the double-sided evaporator offers a novel pathway for the future development of high-performance solar-driven evaporators in large-scale applications.

Traditional materials with single electromagnetic interference (EMI) shielding performance have not satisfied the demand of rapidly developed information and communication technology, which spawns the development of novel materials with higher efficiency and more functionality. However, it is quite difficult to strike a good balance between EMI shielding performance and other functions, such as infrared stealth, which extremely limits the further application, especially in the special or extreme condition. Herein, a novel functional membrane with bifacial architecture was fabricated via the facile solution strategy, which was constructed by the in-situ generation and unidirectional growth Ag nanoparticles and selectively enrichment of Ti 3 C 2 T x sheets on upside and backside of the membrane, respectively. The composite membrane possessed the excellent antibacterial and EMI shielding performance, with the distinctive bifacial wettability and conductivity. Furthermore, the incorporation of Ti 3 C 2 T x effectively reduced the infrared emissivity and endowed the membrane with the infrared stealth performance, providing the novel strategy for constructing multi-functional materials with required structure, showing broad application prospects in the military field.

The Cu@Ag core-shell particles are the highly anticipated functional materials in electronic applications which are required to be high electrical conductivity, good thermal properties and low cost. However, it remains a challenge to obtain a completely and uniformly coated Ag shell in low silver content. During the coating process, it is essential to regulate the reduction of Ag + on the surface of Cu to ensure uniformly silver shell. We developed a strategy to prepare uniformly coated Cu@Ag particles by employing hydroxy acids as complexing agents with “double-sided adhesive” function. Compared to conventional complexing agents, the employed hydroxy acids can not only coordinate with Ag + but also complex with Cu due to the more carboxyl and hydroxyl groups which act like a “double-sided adhesive”, that can pull Ag + to the surface of Cu, and then accomplish the coating of Ag with replacement and reduction reaction. The impact of different types of hydroxy acids as complexing agents on the coating effect of silver-clad copper powder was investigated when the silver addition was 15 %. Results indicated that the obtained Cu@Ag particles with tannic acid as complexing agent show high coating quality layer with low surface sliver content (11.4 %). Moreover, the obtained Cu@Ag particles exhibit good dispersibility, promising thermal stability and low electrical resistivity (30 μΩ·cm).

Power generation and architectural beauty are equally important for designing efficient and esthetically appealing bifacial perovskite solar cells (PSCs). In this work, efficient and multicolored p-i-n-structured PSCs are achieved by taking advantage of a dielectric/metal/dielectric (DMD)-type (MoO3/Ni/Ag/MoO3) transparent counter electrode. The MoO3/Ni underlayer effectively promotes the formation of a continuous and conductive ultrathin Ag transparent film, especially the 1 nm Ni seed layer adjusts the interface energy level between perovskite/MoO3 and Ag, resulting in Ohmic contact of the electrode to promote charge extraction and collection. The upper MoO3 layer with varied thicknesses realizes a spectrally selective antireflection coating, enhancing the rear-side efficiency and forming vivid rear-side colors by optical tuning. As a result, colorful bifacial perovskite solar cells with 20.6% front-side efficiency and 57.6–74.4% bifacial factor are obtained together with colorful rear-side appearance. The bifacial PSCs exhibit good stability by protection from the upper MoO3 layer. This work highlights an effective electric and optic design of the top electrode for artistic bifacial PSCs.
