    412-416页
    查看更多>>摘要：The development of large-scale cell cultivation and non-invasive cell harvesting is highly desired in various fields,including biological regeneration and pharmaceutical research.When using traditional microcarriers for cell culture,trypsinization is often necessary during cell collection,leading to par-tial cells damage.In this work,we developed a thermoresponsive glass microcarrier modified with poly(γ-propargyl-ʟ-glutamate)(PPLG)and poly(N-isopropylacrylamide)(PNIPAM).We utilized these mi-crocarriers for three-dimensional cell culture and enzyme-free cell harvesting,and the results indicated that the prepared microcarriers exhibited excellent non-invasive cell culture performance.

    查看更多>>摘要：Developing efficient and long wavelength sensitive unimolecular photoinitiators(PIs)is still facing a great challenge.In this work,a series of thioxanthone-based N-hydroxyphthalimide esters(TX-NHPIEs)were synthesized by installing NHPIEs along the TX backbone and characterized.The investigated TX-NHPIEs have a 60 nm redshift and demonstrate sterling initiating efficiency for free radical photopolymeriza-tion(FRP)under LED@450 nm light irradiation compared with the commercialized isopropylthioxanthone(ITX).Real-time 1Hnuclear magnetic resonance(1H NMR),electron spin resonance(ESR),decarboxylation and gas chromatograph-mass spectrometer(GC-MS)experiments and density functional theory(DFT)re-veal that TX-NHPIEs can generate one alkyl radical and one N-centered iminyl radical,which can initiate FRP directly and indirectly,respectively.In other words,TX-NHPIEs absorb one photon and can generate two active radicals,which break through the limitations of common PIs.TX-NHPIE-Cpe demonstrates the highest initiating efficiency,and its application in coatings and 3D printing was also studied,indicating TX-NHPIEs have broad potential applications in photopolymerization processes.

    Efficient photocatalytic biomass-alcohol conversion with simultaneous hydrogen evolution over ultrathin 2D NiS/Ni-CdS photocatalyst

    Zongyi HuangCheng GuoQuanxing ZhengHongliang Lu...
    422-427页
    查看更多>>摘要：The photocatalytic conversion of biomass into high-value chemicals,coupled with simultaneous hydro-gen(H2)evolution,leveraging the electrons and holes generated by solar energy,holds great promise for addressing energy demands.In this study,we constructed a dual functional photocatalytic system formed by NiS loaded on Ni doped two-dimensional(2D)CdS nanosheet(NiS/Ni-CdSNS)heterostructure for visible-light-driven H2 evolution and ethanol oxidation to acetaldehyde.Remarkably,the 2D NiS/Ni-CdSNS exhibited significant activity and selectivity in both photocatalytic H2 evolution and ethanol oxi-dation,achieving yields of 7.98mmol g-1 h-1 for H2 and 7.33mmol g-1 h-1 for acetaldehyde.The hetero-geneous interface of the composite facilitated efficient charge separation,while NiS provided abundant sites for proton reduction,thereby promoting the overall dual-functional photocatalytic activity.Density functional theory calculations further reveal that both Ni doping and NiS loading can reduce the reac-tion energy barrier of ethanol oxidation of free radicals,and NiS/Ni-CdSNS composite materials exhibit stronger ethanol C-H activation ability to generate key intermediate·CH(OH)CH3 on the surface.This work serves as a valuable guide for the rational design of efficient dual functional photocatalytic systems that combine H2 evolution with the selective conversion of organic compounds into high-value chemicals.

    Exceptional activity of amino-modified rGO-immobilized PdAu nanoclusters for visible light-promoted dehydrogenation of formic acid

    428-432页
    查看更多>>摘要：Formic acid(FA),which is obtainable through CO2 hydrogenation with green hydrogen or biomass con-version,has been used as a prospective liquid organic hydrogen carrier(LOHC)because of the abundant advantages of renewability,wide availability,stability,and high volumetric capacity(53g H2/L).The de-velopment of highly efficient catalytic systems to achieve enhanced catalytic activity is attractive but still challenging.Herein,ultrafine and highly dispersed PdAu nanoclusters(NCs)anchored on amino-modified reduced graphene oxide(ArGO)were successfully synthesized via a facile impregnation-reduction method and applied as a catalyst toward formic acid dehydrogenation(FAD).Benefiting from the promoting ef-fect of amino groups,the strain and ligand effect in the alloy,and the Mott-Schottky effect between PdAu NCs and ArGO,the resultant PdAu/ArGO affords an ultrahigh activity under visible light irradiation with an exceptional turnover frequency value of 10,699.5h-1 at 298 K without any additives,more than 2.6 times improvement than that under dark,which is the highest among all reported catalysts under the same conditions.This study provides a green and convenient strategy for developing more efficient and sustainable FAD catalysts and promotes the effective utilization of FA as a prospective renewable LOHC.

    Wettability-driven synergistic resistance of scale and oil on robust superamphiphobic coating

    Yixuan WangJiexin LiZhihao ShangChengcheng Feng...
    433-438页
    查看更多>>摘要：Disgusting deposits(e.g.,scale and crude oil)in daily life and industrial production are always serious problems,posing great threats to the safety and economic development.However,most of developed coatings can only conquer one part of these deposits such as superhydrophobic coatings possess anti-scaling capacity but would adhere crude oil.To integrate scale resistance with oil repellence,we herein report a robust superamphiphobic(SAB)coating simultaneously reducing pollution of scale and oil for extended period of time(two weeks with over 98% reduction).Compared with single role of superhy-drophobic and amphiphilic surfaces,the SAB coating can not only inhibit interfacial nucleation of scale but also reduce the adhesion of formed scale and polluted oil.The durability of the SAB coating is eval-uated via mechanical tests(sandpaper abrasion,tape stripping and sand falling)and chemical corrosion(corrosive liquid immersing),revealed by sustainable high contact angles and low contact angle hysteresis of water and oil.The universality of this strategy can be further confirmed by adding different particles like kaolin,Al2O3,and SiO2,resisting multiple types of scale(i.e.,CaSO4,BaSO4 and MgCO3)and oil(i.e.,glycerol,glycol,and mineral oil).Therefore,this study provides an ideal avenue for resisting scale and oil,which may be used for conquering the complexity of application environments(e.g.,oil production and transportation).

    439-444页
    查看更多>>摘要：Two-dimensional(2D)mesoporous pseudocapacitive polymer/graphene heterostructures combine the ad-vanced merits of 2D materials and mesoporous materials,possessing unique nanosheet structure,large specific surface area(SSA),abundant oxygen/nitrogen-containing groups,desirable electrical conductivity and admirable electrochemical redox activity,and hold great potential for constructing high-performance planar micro-supercapacitors(MSCs).Herein,we demonstrate the interfacial assembly of 2D mesoporous polydopamine/graphene(mPDG)heterostructures with well-defined mesopore structure(12nm)and ad-justable thickness(7.5-14.1nm)for planar high-energy pseudocapacitive MSCs.Attributed to medium thickness,exposed mesopore of 12nm and large SSA of 108 m2/g,the mPDG with 10.8nm thickness reveals prominent mass capacitance of 419 F/g and impressive cycling stability with ∼96% capacitance retention after 5000 cycles.Furthermore,the symmetric mPDG-based MSCs with"water-in-salt"gel elec-trolyte present wide voltage window of 1.6 V,superior volumetric energy density of 11.5 mWh/cm3,out-standing flexibility and self-integration ability.Therefore,this work offers a new platform of controllably synthesizing 2D mesoporous heterostructures for high-performance MSCs.

    Molecular crowding electrolytes for stabilizing Zn metal anode in rechargeable aqueous batteries

    Li LinSong-Lin TianZhen-Yu HuYu Zhang...
    445-451页
    查看更多>>摘要：A solid electrolyte interphase(SEI)with a robust mechanical property and a high ionic conductivity is imperative for high-performance zinc metal batteries.However,it is difficult to form such a SEI directly from an electrolyte.In this work,a molecular crowding effect is based on the introduction of Zn(OTF)2 and Zn(ClO4)2 to 2mol/L ZnSO4 electrolytes.Simulations and experiments indicate that the Zn(OTF)2 and Zn(ClO4)2 not only create a molecularly crowded electrolyte environment to promote the interaction of Zn2+and OTF-,but also participate in the reduction to construct a robust and high ionic-conductive SEI,thus promoting metal zinc deposition to the(002)crystal surface.With this molecular crowding elec-trolyte,a high current density of 1 mA/cm2 can be obtained by assembling symmetric batteries with Zn as the anode for over 1000h.And in a temperature environment of-10℃,a current density of 1mA/cm2 can be obtained by assembling symmetric batteries with Zn for over 200h.Zn//Bi2S3/VS4@C cells achieve a CE rate of up to 99.81％ over 1000 cycles.Hence,the utilization of a molecular crowding electrolyte is deemed a highly effective approach to fabricating a sophisticated SEI for a zinc anode.

    Re-evaluating the nano-sized inorganic protective layer on Cu current collector for anode free lithium metal batteries

    Shuo ZhangHaitao LiaoZhi-Qun LiuChong Yan...
    452-455页
    查看更多>>摘要：Anode free lithium metal batteries(AF-LMBs)have conspicuous advantages both in energy density and the compatibility of battery manufacturing process.However,the limited cycle life of AF-LMBs is a crucial factor hindering its practical application.Fluorinated or nitride artificial inorganic solid electrolyte interphase(SEI)has been found as an effective method to prolong the lifespan of AF-LMBs.Herein,by investigating the impact of nano-sized inorganic gradient layers(LiF or Li3N)on initial Li deposition behavior,we notice that the Li+ diffusion barrier and the deposition morphology are highly depended on the thickness of inorganic layers.Thicker protective layers cause larger overpotential as well as more aggregated Li+ distribution.This study reveals that the ideal SEI should be synthesized thin and uniformly enough and uncontrollable artificial SEI can cause damage to the lifespan of AF-LMBs.

    查看更多>>摘要：Constructing composited electrode material is considered to be an efficient strategy to improve their elec-trochemical performance.It can accelerate the charge transfer speed of ions and enhance the conductivity of electrode.Meanwhile,the formation of the hybrid structure can largely avoid the aggregation of two dimensional materials and increase the electrochemical active area of the electrode.In this work,we synthesize NiMoSSe electrode materials on nickel foam by a facile hydrothermal avenue.The prepared composite shows a specific capacitance of 1035 C/g at 1 A/g due to the synergistic effect between MoS2 and MoSe2 phases.In addition,the devices are assembled with NiMoSSe samples,which offers an energy density of 82.71 Wh/kg at a power density of 2700 W/kg.

    Dual-functional POM@IL complex modulate hole transport layer properties and interfacial charge dynamics for highly efficient and stable perovskite solar cells

    Boyuan HuJian ZhangYulin YangYayu Dong...
    461-464页
    查看更多>>摘要：The severe interfacial charge recombination as well as the stability issues brought by the Li-TFSI still hinder the commercialization of high-performance perovskite solar cells(PSCs).Here,a polyoxometalates(POMs)-based complex,POM@ionic liquid(IL),is synthesized and applied as an effective additive that si-multaneously enhances the performance and stability of PSCs.The interactions between POM@IL complex and Li-TFSI inhibit the aggregation of Li-TFSI.The synergistic oxidation of POM@IL complex and Li-TFSI towards 2,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene(Spiro-OMeTAD)effectively enhances the electrical properties of hole transport layer film and the photovoltaic performances of PSCs.The champion device modified with the POM@IL complex yields an excellent power conversion efficiency(PCE)of 22.73% .Moreover,the incorporation of POM@IL improves the humidity stability of PSCs.After storing under high humidity conditions(25℃,60% RH)for 1200 h,the POM@IL modified device retained a remarkable 81.2% of its initial PCE.This work provides new insight into constructing POMs-based ma-terials for high-performance photovoltaic devices.
