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.

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.

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.

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).

The carrier recombination loss induced by defects, imperfect contact and energy level barriers at the buried interface severely restricts the greater advancement of comprehensive performance of perovskite solar cells (PSCs). Herein, a versatile inorganic ammonium salt of diammonium hydrogen phosphate (DAP) is exploited as a “double-sided tape” modifier to be deposited at the TiO2/perovskite buried interface, which not only passivates the surface defects of TiO2 and perovskite layers and simultaneously bridges the two films via the chemical reactions of hydrogen phosphate anions and ammonium cations in DAP with TiO2 and CsPbBr3 perovskite, respectively, but also ameliorates the interface contact and energy level alignment. Moreover, a higher quality perovskite film with fewer grain boundaries and defects is tightly formed on the DAP modified TiO2 layer arising from its lower wettability. Consequently, a substantially improved charge transport and extraction and minimized charge recombination are achieved in DAP tailored all-inorganic hole transport layer-free CsPbBr3 PSCs, yielding a power conversion efficiency as high as 10.31% with an impressive open-circuit voltage of 1.621 V, which is highly increased compared to 7.58% for the control device. Furthermore, the optimized device free of encapsulation exhibits a superior long-term stability after exposure to an air atmosphere at 85 °C with 85% RH over 720 h.

Excess exposure to a high environmental level of nickel can cause serious harm to human health. Therefore, it is particularly necessary to develop a low-cost, fast and sensitive method for nickel assay. In this paper, novel counting-based microfluidic paper-based devices (μPADs) were prepared by hand drawing and yellow oily double-sided adhesive tape. The dissolved adhesive tape was used for the first time to make the hydrophobic “ink”. The marker filled with the “ink” drew the desirable layout on paper followed by a drying process. The μPADs were constituted of one circular sample introduction zone (diameter 4.5 mm) and four circular detection zones (diameter 3 mm). The adjoining detection zones were connected by a strip channel (1.2 mm × 2 mm). The fabrication conditions were optimized and the barriers created with the marker revealed good reproducibility. The analytical performance of the developed devices was investigated for nickel assay. The Ni2+ standard was added to the sample introduction zone, and subsequently moved into the detection zones containing dimethylglyoxime (DMG), where it reacted with Ni2+ and formed a reddish pink Ni–DMG complex. Through counting the number of colored dots, the developed μPADs realized the semi-quantitative analysis of nickel. More importantly, the fabrication of the developed counting-based μPADs only used a marker and adhesive tape, possessing the advantages of instrument-free simplicity and low cost. Our method has great potential for enabling μPADs to be easily implemented in laboratories or research centers with limited resources.

Matrix deposition plays a critical role in image quality of matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI). To improve the ionization efficiency and overcome the limitation of traditional matrix deposition methods in the face of difficult-to-sublimate or difficult-to-dissolve matrix, covalent organic frameworks (COFs) named COF-DhaTab was successfully synthesized and firstly used as matrix film. It was fabricated by imprinting of sieved COF-DhaTab powder on the surface of a double-sided adhesive tape. Outstanding reproducibility and uniformity of COF-DhaTab film were demonstrated by relative standard deviation (RSD) within 8.37% and 7.71% from dot-to-dot and plate-to-plate, respectively. With the introduction of double-sided adhesive tape, water contact angle (WCA) of COF-DhaTab film increased from 55° to 141°, resulting in significant suppression of analyte diffusion. Moreover, the intensity of potassium perfluorooctanic sulfonate (PFOS, C 8 F 17 SO 3 − , m/z 498.93) was 9.3 × 10 5 , more than six hundred times higher than that using DHB matrix. This enhancement was attributed to the rough surface and multiple branches of the synthesized COF-DhaTab. To verify the ability of COF-DhaTab film as substrate, the spatial distribution of PFOS in zebrafish, rat liver and kidney tissues was explored. Superior imaging capability was displayed with high-spatial resolution and reliable location distribution. These results not only demonstrate the outstanding ability of COF-DhaTab as matrix for MALDI-MS and MALDI-MSI, but also provide a facile approach for fabrication of novel matrix films for MALDI-MSI.
