Photosynthetic Energy conversion for high-energy chemicals generation is one of the most viable solutions in the quest for sustainable energy towards carbon neutrality.Microalgae are fascinating photosynthetic organisms,which can directly convert solar energy into chemical energy and electrical energy.However,microalgal photosynthetic energy has not yet been applied on a large scale due to the limitation of their own characteristics.Researchers have been inspired to couple microalgae with synthetic materials via biomimetic assembly and the resulting microalgae-material hybrids have become more robust and even perform new functions.In the past decade,great progress has been made in microalgae-material hybrids,such as photosynthetic carbon dioxide fixation,photosynthetic hydrogen production,photo electrochemical Energy conversion and even biochemical Energy conversion for biomedical therapy.The microalgae-material hybrid offers opportunities to promote artificially enhanced photosynthesis research and synchronously inspires investigation of biotic-abiotic interface manipulation.This review summarizes current construction methods of microalgae-material hybrids and highlights their implication in energy and health.Moreover,we discuss the current problems and future challenges for microalgae-material hybrids and the outlook for their development and applications.This review will provide inspiration for the rational design of the microalgae-based semi-natural biohybrid and further promote the disciplinary fusion of material science and biological science.

Cancer therapies based on Energy conversion,such as photothermal therapy(PTT,light-to-thermal Energy conversion)and photodynamic therapy(PDT,light-to-chemical Energy conversion)have attracted extensive attention in preclinical research.However,the PTT-related hyperthermia damage to surrounding tissues and shallow penetration of PDT-applied light prevent further advanced clinical practices.Here,we developed a thermoelectric therapy(TET)based on thermoelectric materials constructed p-n heterojunction(SrTiO_(3)/Cu_(2)Se nanoplates)on the principle of light-thermal-electricity-chemical Energy conversion.Upon irradiation and natural cooling-induced the temperature gradient(35-45℃),a self-build-in electric field was constructed and thereby facilitated charges separation in bulk SrTiO_(3)and Cu_(2)Se.Importantly,the contact between SrTiO_(3)(n type)and Cu_(2)Se(p type)constructed another interfacial electric field,further guiding the separated charges to re-locate onto the surfaces of SrTiO_(3)and Cu_(2)Se.The formation of two electric fields minimized probability of charges recombination.Of note,high-performance superoxide radicals and hydroxyl radicals’generation from O_(2)and H_(2)O under catalyzation by separated electrons and holes,led to intracellular ROS burst and cancer cells apoptosis without apparent damage to surrounding tissues.Construction of bulk and interfacial electric fields in heterojunction for improving charges separation and transfer is also expected to provide a robust strategy for diverse applications.

Nano Research 2024年第3期17卷 1655-1665页

Currently,as the electromagnetic(EM)environment becomes increasingly complex,single-function EM materials can hardly resist the increasing electromagnetic interference(EMI),and there is an urgent need to develop multifunctional EM materials.In this work,multifunctional WSe_(2)/Co_(3)C was prepared by simple hydrothermal methods.Its dielectric performance and EM response were investigated.Efficient absorption,shielding performance,and Energy conversion devices were customized.By tailoring the loading content,WSe_(2)/Co_(3)C can switch between EM absorption and EMI shielding.The maximum shielding effectiveness(SE)of WSe_(2)/Co_(3)C reached 36 dB,and high reflection loss(RL)of-60.28 dB and wide effective absorption bandwidth(EAB)of 6.16 GHz can be obtained at low thickness.The multiple EM attenuation mechanisms brought by the combination of two-dimensional(2D)WSe_(2) and magnetic Co_(3)C are considered to be the main reason for the enhanced EM attenuation ability.The WSe_(2)/Co_(3)C composite provides a viable candidate for developing multifunctional EM materials in 2–18 GHz.

Metal-organic frameworks(MOFs),a well-known coordination network involving potential voids,have attracted attention for Energy conversion and storage.As far as is known,MOFs are not only believed to be crystalline.Emerging amorphous MOFs(aMOFs)are starting as supplementary to crystalline MOF(cMOF)in various electrochemical energy fields owing to intrinsic superiorities over crystalline states,greater ease of processing,and distinct physical and chemical properties.aMOFs retain the basic skeletons and connectivity of building units but without any long-range order.Such structural features over long range possess the isotropy without grain boundaries,resulting in fast ions flux and uniform distribution.Simultaneously,distinct shortrange characteristics provide diverse pore confined environment and abundant active sites,and thus accelerate mass transport and charge transfer during electrochemical reactions.Deep understandings and controllable design of aMOF may broaden the opportunities for both scientific researches beyond crystalline materials and practical applications.To date,comprehensive reviews about aMOFs in the fields of Energy conversion and storage remain woefully underrepresented.Herein,we summarize the roadmap of aMOF from the development,structural design,opportunity,application,bottleneck,and perspective.In-depth structure-activity relationships with aMOF chemistry are highlighted in the typical electrochemical Energy conversion like water oxidation and energy storage,including supercapacitor and battery.The combination of disordered nature at long range and short range,alongside the dynamic structural changes,is promising to reinforce cognition of aMOF domains with MOF versatility,shedding light on the design for efficient electrochemical energy applications via amorphization.

Two-dimensional(2D)mesoporous materials(2DMMs),defined as 2D nanosheets with randomly dispersed or orderly aligned mesopores of 2–50 nm,can synergistically combine the fascinating merits of 2D materials and mesoporous mate-rials,while overcoming their intrinsic shortcomings,e.g.,easy self-stacking of 2D materials and long ion transport paths in bulk mesoporous materials.These unique features enable fast ion diffusion,large specific surface area,and enriched adsorption/reaction sites,thus offering a promising solution for designing high-performance electrode/catalyst materials for next-generation energy storage and conversion devices(ESCDs).Herein,we review recent advances of state-of-the-art 2DMMs for high-efficiency ESCDs,focusing on two different configurations of in-plane mesoporous nanosheets and sandwich-like mesoporous heterostructures.Firstly,a brief introduction is given to highlighting the structural advantages(e.g.,tailored chemical composition,sheet configuration,and mesopore geometry)and key roles(e.g.,active materials and functional additives)of 2DMMs for high-performance ESCDs.Secondly,the chemical synthesis strategies of 2DMMs are summarized,including template-free,2D-template,mesopore-template,and 2D mesopore dual-template methods.Thirdly,the wide applications of 2DMMs in advanced supercapacitors,rechargeable batteries,and electrocatalysis are discussed,enlightening their intrinsic structure–property relationships.Finally,the future challenges and perspectives of 2DMMs in energy-related fields are presented.

The effect of the guide field on Energy conversion during collisionless magnetic reconnection

Magnetic reconnection is well known as an efficient mechanism for transferring magnetic energy into plasma energy.However,how the Energy conversion and partition between different species is influenced by the shear angle of the reconnecting magnetic component(i.e.,the guide field strength)is not well understood.Using 2.5-dimensional particle-in-cell simulations,we investigated the Energy conversion in reconnection with different guide fields.We found that the overall Energy conversion first decreases steeply and then increases slowly when the guide field increases fromB_(g)=0 toB_(g)=4.The increase in Energy conversion in the large guide field regime is due to the electron energy gain through the perpendicular channelJ_(⊥)·E_(⊥).The overall Energy conversion is predominantly contributed byJ_(⊥)·E_(⊥) rather thanJ||E||.We further find that Energy conversion mainly occurs within the reconnection front and the flux pileup region.However,the contribution from the fore reconnection front becomes important in large guide field regimes(3energy gain.

Flexible wearable ultraviolet(UV)shielding,monitoring and warning devices have important applications in civil and mili-tary fields.However,most flexible wearable UV devices show unsatisfactory performance due to their poor stability and easy failure at large strains.Herein,inspired by tree rings,we engineered a hierarchical composite nanofibrous helix with an alternately stacked Archimedes spiral structure via a cost-effective strategy.Based on a photo-electricity-acoustic Energy conversion system,we fabricated an all-in-one device exhibiting strain-insensitive UV protection at 0–500%strain for UV shielding as well as strain-sensitive UV monitoring at 500–1500%strain for UV early warning.Compared with previously reported common nanofibrous membrane devices,the as-prepared composite nanofibrous helix shows great advantages in terms of stability and UV protection,especially at large strains.Furthermore,the helix demonstrates multiple functions of wear resistance,antibacterial properties,biodegradation and knittability.This versatile strategy holds great promise for wearable electronics and multifunctional devices.
