In this work, we found that the high-performance polymer solar cells suffer from significant performance decay upon thermal annealing at 150 °C owing to the fast decay of VOC and FF. We demonstrated that the thermal annealing process leads to a severe chemical reaction of MoO3 with Al, forming an Al2O3 barrier layer at the MoO3/Al interface, which lowers the built-in potential (Vbi) of the cells and consequently reduces charge collection efficiency. Inserting a thin C60 interlayer between MoO3/Al slows the chemical reaction of MoO3 with Al, which ensures a high Vbi and charge collection efficiency for the annealed MoO3/C60/Al cells. Such a protection effect of the C60 layer in improving device performance against thermal annealing was also confirmed for cells with different polymer photoactive layers and metal electrodes, demonstrating the generality of the interfacial degradation of the cells and the protection effect of the C60 layer. Finally, we demonstrated that the inverted polymer solar cells with the C60-modified anode showed almost no performance decay upon high-temperature hot-press encapsulation, demonstrating excellent heat tolerance of this new device structure.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study prepared a hydrogen-free compound, BLG-102, with high nitrogen content (66.6%) using an energetic block design based on a long nitrogen chain (N6). BLG-102 has a high crystal density of 1.85 g·cm–3, with a measured crystal density of 1.82 g·cm–3. It also achieves zero oxygen balance (based on CO), excellent enthalpy of formation, and good conjugate planarity and aromaticity. BLG-102 demonstrates exceptional detonation performance with a high detonation velocity (VD = 9311 m·s–1) and detonation pressure (P = 38.5 GPa). These values are superior to the well-known energetic compound RDX (VD = 8991 m·s–1, P = 35.2 GPa), and are comparable to HMX (VD = 9144 m·s–1, P = 39.2 GPa). Nevertheless, BLG-102 exhibits slightly higher but acceptable sensitivity (IS = 5 J, FS = 54 N). BLG-102 demonstrates remarkable capabilities in laser initiation. Notably, a 10 mg charge of BLG-102 can effectively detonate 20 mg of RDX, producing a pore diameter of 11.44 mm in the lead plate (2 mm thick). The integrated design approach using the block design concept─combining nitro, azide, and long nitrogen chain structures with a 1,2,4-triazole framework─significantly enhances the energy performance of 1,2,4-triazole compounds. It breaks through the energy limit of already known 1,2,4-triazole-based compounds and provides a new idea for the design and synthesis of HEDMs with high performance.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"51 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The actuator demonstrates multistimuli responsiveness to organic solvents/vapors, thermal radiation, and infrared (IR) radiation in air, achieving bidirectional deformation under organic stimuli with a remarkable bending angle of 630° and a load capacity of 180 times its self-weight. In aqueous environments, the actuator exhibits minimal response to thermal and IR light stimuli but shows high selectivity and rapid response to specific organic pollutants, with a response time of just 1.77 s to dichloromethane. Leveraging these properties, we developed a series of functional actuators─including Miura origami, airfoil, and artificial muscle configurations─demonstrating their capability to replicate complex movements. Moreover, a water lily-inspired multienvironmental actuator was designed to effectively shield against underwater temperature fluctuations, IR light, and nontarget organic solvent interference, showing its cross-insensitivity and potential for real-time environmental monitoring applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"46 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, an anti-swelling and self-healing hydrogel is prepared by grafting poly(acrylic acid) with hydrophobic lauryl methacrylate, as well as constructing a second network and multiple molecular interactions (abbreviated as PALCF). The introduced hydrophobic long alkyl chains and the increased cross-linking density of the hydrogel result in a swelling ratio of only 0.04% after immersion in water for 15 days. Due to abundant metal coordination and hydrogen bonds, the PALCF hydrogel exhibits a high tensile stress of 0.60 MPa and a self-healing efficiency reaching 96.0% after self-healing at 60 °C for 2 min. Based on the piezoresistive effect, the PALCF hydrogel is directly used as an underwater strain sensor with a high sensitivity (GF = 2.24) to control underwater vehicles for rescue implementation. Furthermore, two self-powered triboelectric nanogenerator sensors with contact and non-contact models are constructed based on PALCF hydrogels for underwater communication, capable of sending out SOS messages and drowning alarms in emergency. The proposed underwater sensors with drowning warning and rescuing functions have the potential for use in drowning prevention, human–machine interfaces, and underwater communication system.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"6 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important catalyst for oxygen electrocatalyst is an atomically dispersed iron atom embedded in the nitrogen-doped carbon (Fe-NC) material. However, the unsuitable binding energy between the center Fe atom and the reaction intermediate leads to the sluggish oxygen electrocatalyst reaction rate. The regulation of the electron structure of the Fe atom by adjusting the coordinate structure is one effective solution. Here, we prose the substitution of nitrogen atom by sulfur atom, who has weak electronegativity and can donor electron to Fe atom, so the d-band center of Fe atom is elevated. Thus, the Fe-NS active site facilitates the fast *OOH adsorption and the *OH desorption, compared with counterpart Fe-N active site. As a result, the oxygen electrocatalyst reaction kinetics is accelerated. The Fe-NSC catalyst has good compatibility and performance in aqueous rechargeable Zn–air batteries, affording stable charge/discharge process for 1000 h/3000 cycles with a high voltage tolerance (0.74–0.96 V voltage gap) under 10 mA cm–2.

Although optical manipulation provides precise particle control, its application is often limited by high energy requirements and intricate setups. In this study, we present an opto-chemical-electronic tweezer (OCET), a novel particle manipulation strategy that addresses these limitations. The OCET system utilizes a photocatalytic TiO2/Pt film irradiated with perpendicular UV light. An electric field is then generated parallel to the film at the boundary of the patterned UV light, directed from the illuminated region to the dark region. The consequent electrophoresis and electroosmosis work in tandem to move inert colloidal particles (e.g., SiO2 microspheres) at ∼1 μm/s and trap them a few μm inside the illuminated region along the boundary of the light pattern. By dynamically modulating light patterns, the OCET system achieves directional particle transport and reconfigurable colloidal assembly into arbitrary patterns. The OCET system holds promise for applications in optofluidics, micro/nanorobotics, and biomedical systems, setting the stage for further advancements in optical manipulation technologies.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"63 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ordered structures formed by block copolymer self-assembly can provide an orientation matrix for nonspherical nanoparticles. Based on self-consistent field theory, this study investigates the orientation effects of monaxially symmetric cylindrical nanoparticles in the lamellar phases formed by block copolymers. Using cylindrical and pore-containing ring nanoparticles as models for nonspherical particles, we successfully describe the particles’ anisotropy and nonconvex surface properties. Numerical results show that the orientation effect of the lamellar ordered structure exhibits a nontrivial dependence on the geometric and topological properties of nonspherical particles. In addition to interfacial tension effects, the orientation mechanism of small-sized nanoparticles mainly arises from the stretching effect of the polymer, manifested in two main effects: (1) the particle deforms the polymer chain, reducing its conformational entropy, thus tending to align in a specific orientation; (2) the orientation field at the polymer chain ends is discontinuous, and the nanoparticles can embed and adopt a specific orientation. For nonconvex nanoparticles, the geometric size of the pore structure adjusts the polymer’s free volume, influencing the orientation effect. This study not only deepens the understanding of the orientation mechanism in block copolymer-mediated nanoparticle self-assembly, but also provides potential theoretical insights for the design and application of energy catalysis, biomedical materials, and functional nanostructures.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"24 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we address this issue by developing a hydroxyl-induced anti-aggregation strategy by introducing a suitable amount of hydroxypropyl cellulose (HPC) into the solution of PDINN, and a careful balance is achieved between the film-forming quality and the aggregation of the material. Taking two commercially available active layer systems, PM6/Y6 and D18/L8-BO, as examples, the introduction of HPC significantly increases the JSC and FF values of the devices. Therefore, power conversion efficiency risen from 17.38% to 18.25% for the PM6/Y6 system and from 18.45% to 19.73% for the D18/L8-BO system, and it was proved that the thickness tolerance of the HPC hybrid interface was improved significantly.
