文摘Post-earthquake rescue missions are full of challenges due to the unstable structure of ruins and successive aftershocks.Most of the current rescue robots lack the ability to interact with environments,leading to low rescue efficiency.The multimodal electronic skin(e-skin)proposed not only reproduces the pressure,temperature,and humidity sensing capabilities of natural skin but also develops sensing functions beyond it—perceiving object proximity and NO2 gas.Its multilayer stacked structure based on Ecoflex and organohydrogel endows the e-skin with mechanical properties similar to natural skin.Rescue robots integrated with multimodal e-skin and artificial intelligence(AI)algorithms show strong environmental perception capabilities and can accurately distinguish objects and identify human limbs through grasping,laying the foundation for automated post-earthquake rescue.Besides,the combination of e-skin and NO2 wireless alarm circuits allows robots to sense toxic gases in the environment in real time,thereby adopting appropriate measures to protect trapped people from the toxic environment.Multimodal e-skin powered by AI algorithms and hardware circuits exhibits powerful environmental perception and information processing capabilities,which,as an interface for interaction with the physical world,dramatically expands intelligent robots’application scenarios.

文摘Au is considered as one of the most promising catalysts for nitrogen reduction reaction(NRR),however maximizing the activity utilization rate of Au and understanding the synergistic effects between Au and carriers pose ongoing challenges.Herein,we systematically explore the synergistic catalytic effect of incorporating Au with boron clusters for accelerating NRR kinetics.An in-situ abinitio strategy is employed to construct B-doped Au nanoparticles(2-6 nm in diameter)loaded on BO_(x) substrates(AuBO_(x)),in which B not only modulates the surface electronic structure of Au but also forms strong coupling interactions to stabilize the nanoparticles.The electrochemical results show that Au-BO_(x) possesses excellent NRR activity(NH_(3) yield of 48.52μg h^(-1)mg_(cat)^(-1),Faraday efficiency of 56.18%),and exhibits high stability and reproducibility throughout the electrocatalytic NRR process.Theoretical calculations reveal that the introduction of B induces the formation of both Au dangling bond and Au-B coupling bond.which considerably facilitates the hydrogenation of~*N_(2)^(-)~*NH_(3).The present work provides a new avenue for the preparation of metal-boron materials achieved by one-step reduction and doping process,utilizing boron clusters as reducing and stabilizing agents.

文摘As the high calibre candidate of lightweight and flexible solar cells,polymer solar cells(PSCs)have made tremendous progress in recent years.However,the active photovoltaic materials in PSCs are mainly synthesized by metal-mediated coupling reaction requiring harsh reaction conditions,multiple-step synthesis,and cumbersome purification,which is not cost-efficient and may bring toxicity concerns.It is not favorable to the production of photovoltaic polymers and PSC devices on a large scale,and therefore unsuitable for the PSCs industrialization.Direct arylation coupling reaction via aromatic C―H bonds activation enables the synthesis of conjugated polymers under mild conditions and simultaneously reduces synthetic steps,difficulty,and toxic reaction byproducts.This review provides an overview of the history of preparing representative photovoltaic polymers utilized in PSCs through direct arylation reactions and discusses the activity and selectivity of C―H bonds in typical building blocks under different reaction conditions.Especially,the impact of direct arylation condition on defect formation and photovoltaic performance of the photovoltaic polymers is addressed and compared with conventional Stille coupling methods.

文摘The interfacial contacts between the electron transporting layers(ETLs)and the photoactive layers are crucial to device performance and stability for OSCs with inverted architecture.Herein,atomic layer deposition(ALD)fabricated ultrathin Al_(2)O_(3)layers are applied to modify the ETLs/active blends(PM6:BTP-BO-4F)interfaces of OSCs,thus improving device performance.The ALD-Al_(2)O_(3)thin layers on ZnO significantly improved its surface morphology,which led to the decreased work function of ZnO and reduced recombination losses in devices.The simultaneous increase in open-circuit voltage(V_(OC)),short-circuit current density(J_(SC))and fill factor(FF)were achieved for the OSCs incorporated with ALD-Al_(2)O_(3)interlayers of a certain thickness,which produced a maximum PCE of 16.61%.Moreover,the ALD-Al_(2)O_(3)interlayers had significantly enhanced device stability by suppressing degradation of the photoactive layers induced by the photocatalytic activity of ZnO and passivating surface defects of ZnO that may play the role of active sites for the adsorption of oxygen and moisture.

文摘Improving the optoelectronic behavior and stress-deformation stability of conjugated materials is crucial for the realization of their potential applications in flexible optoelectronics.To tune the emission behavior and mechanical property of molecular crystals simultaneously via supramolecular salt strategy is rarely reported,which is very important to improve their photophysical behavior and softness for the fabrication of flexible light-emitting device.Herein,supramolecular salt approach has been successfully applied to synthesize two elastic organic fluorescent crystals(CMOH-Py-Cl and CMOH-Py-Br)derived from non-emissive and brittle pyridine-substituted coumarin derivative(CMOH-Py).Their elastic properties can be attributed to the prevalent presence of numerous weak interactions introduced by halogen atoms,which are beneficial to the absorption and release of mechanical energy.Furthermore,density functional theory(DFT)calculations demonstrated a narrowing of the HOMO-LUMO energy gaps from CMOH-Py to CMOH-Py-Cl/CMOH-Py-Br via supramolecular salt approach.Finally,the application of flexible crystal materials in the field of optical waveguides has been investigated.The transformation of crystals in terms of photophysical and mechanical properties,achieved by the supramolecular salt approach,offers novel insights into the design and construction of flexible crystalline materials,providing a new path for the development of next-generation smart materials.

文摘Metal halide perovskites,owing to their remarkable optoelectronic properties and broad application prospects,have emerged as a research hotspot in materials science and photovoltaics.In addressing challenges related to energy loss,photoelectric conversion efficiency,and operational stability in perovskite solar cells(PSCs),various strategies have been proposed,such as improving perovskite crystallization,developing tandem architectures,and advancing interfacial engineering.However,the specific impact of these approaches on internal energy transfer and conversion mechanisms within PSCs remains insufficiently understood.This review systematically examines the relationship between energy and perovskite materials throughout the photon absorption to charge carrier transport process,with particular focus on key strategies for minimizing energy losses and their underlying influence on energy-level alignment-especially in the electron transport layer and hole transport layer.It summarizes optimal absorption conditions and contributing factors during energy transfer,alongside representative case studies of high-performing systems.By elucidating these mechanisms,this work offers valuable theoretical insights for optimizing energy-level alignment,reducing energy dissipation,and guiding experimental design in PSCs research.

文摘Perovskite solar cells(PSCs)have attracted considerable interest due to their excellent optoelectronic properties.However,while single-junction PSCs have achieved remarkable efficiencies,factors such as a limited range of developed perovskite materials and immature fabrication processes have constrained their commercialization.Achieving the development of perovskite materials and the preparation of highperformance devices at low cost is a key challenge for the commercialization of PSCs.To address this challenge,machine learning(ML)has been widely applied in the field of PSCs.This paper briefly introduces the basic workflow of ML,providing a foundational understanding for further research on its applications in the PSCs domain.Subsequently,the paper systematically reviews the relevant applications of ML in the PSCs field.Finally,it summarizes the key factors that need to be considered for ML-empowered PSCs and highlights the future directions that should be continuously monitored for development.

文摘Poor wettability of poly(triarylamine)(PTAA)surfaces and insufficient control over residual PbI_(2) clusters remain critical bottlenecks limiting the performance of PTAA-based p-i-n perovskite solar cells(PSCs).Herein,we introduce an effective interface engineering strategy through the incorporation of the ionic liquid 1-butyl-3-methylimidazolium acetate(BMIMAc).Owing to its strong affinity for the perovskite precursor solvent(N,N-dimethylformamide,DMF),BMIMAc significantly enhances PTAA wettability,promoting the formation of uniform and defect-passivated perovskite films.In addition,BMIMAc modulates the energy level alignment of PTAA,facilitating more efficient hole extraction and transport across the interface.More importantly,BMIMAc interacts with PbI_(2) to decelerate perovskite crystallization kinetics,enabling a more complete conversion of PbI_(2) into the perovskite phase.This synergistic regulation yields perovskite films with enlarged grain sizes,reduced trap densities,and suppressed nonradiative recombination losses.Benefiting from these advances,the optimized PTAA-based p-i-n PSCs achieve a record-high power conversion efficiency of 25.10%with significantly enhanced operational stability.
