    查看更多>>摘要：Ligament cryopreservation enables a prolonged shelf life of allogeneic ligament grafts,which is funda-mentally important to ligament reconstruction.However,conventional cryopreservation techniques fail to eliminate the damage caused by ice crystal growth and the toxicity of cryopreservation agents(CPAs).Here,we report a novel CPA vitrification formulation primarily composed of betaine for ligament cryopreservation.Comprehensive optimization was conducted on the methods for vitrification and rewarming,as well as the loading and unloading conditions,based on the critical cooling rate(CCR),critical warming rate(CWR),and permeation properties of the CPA.Using biomechanical and histological level tests,we demonstrate the superior performance of our method in ligament cryopreservation.After 30 days of vitrification cryopreservation,parameters such as the Young's modulus,tensile stress,denaturation temperature,and glycosaminoglycans content of the ligament remained essentially un-changed.This work pioneers the application of ice-free cryopreservation for ligament and holds great potential for improving the long-term storage of ligament,providing valuable insights for future cryo-preservation technique development.

    19-25页
    查看更多>>摘要：The key factor in photothermal therapy lies in the selection of photothermal agents.Traditional pho-tothermal agents generally have problems such as poor photothermal stability and low photothermal conversion efficiency.Herein,we have designed and synthesized an isoindigo(IID)dye.We used iso-indigo as the molecular center and introduced common triphenylamine and methoxy groups as rotors.In order to improve the photothermal stability and tumor targeting ability,we encapsulated IID into nanoparticles.As a result,the nanoparticles exhibited high photothermal stability and photothermal conversion efficiency(67％)upon 635 nm laser irradiation.Thus,the nanoparticles demonstrated a significant inhibitory effect on live tumors in photothermal therapy guided by photoacoustic imaging and provided a viable strategy to overcome the treatment challenges.

    查看更多>>摘要：Acetic acid and furfural are known as prevalent inhibitors deriving from pretreatment during lignocel-lulosic ethanol production.They negatively impact cell growth,glucose uptake and ethanol biosynthesis of Saccharomyces cerevisiae strains.Development of industrial S.cerevisiae strains with high tolerance towards these inhibitors is thus critical for efficient lignocellulosic ethanol production.In this study,the acetic acid or furfural tolerance of different S.cerevisiae strains could be significantly enhanced after adaptive evolution via serial cultivation for 40 generations under stress conditions.The acetic acid-based adaptive strain SPSC01-TA9 produced 30.5 g·L-1 ethanol with a yield of 0.46 g·g-1 in the presence of 9 g·L-1 acetic acid,while the acetic acid/furfural-based adaptive strain SPSC01-TAF94 produced more ethanol of 36.2 g·L-1 with increased yield up to 0.49 g·g-1 in the presence of both 9 g·L-1 acetic acid and 4 g·L-1 furfural.Significant improvements were also observed during non-detoxified corn stover hy-drolysate culture by SPSC01-TAF94,which achieved ethanol production and yield of 29.1 g·L-1 and 0.49 g g-1,respectively,the growth and fermentation efficiency of acetic acid/furfural-based adaptive strain in hydrolysate was 95％higher than those of wildtype strains,indicating the acetic acid-and furfural-based adaptive evolution strategy could be an effective approach for improving lignocellulosic ethanol production.The adapted strains developed in this study with enhanced tolerance against acetic acid and furfural could be potentially contribute to economically feasible and sustainable lignocellulosic biorefinery.

    Modeling solubility of oxaprozin and irbesartan in biorelevant complex solutions based on a combination of pH-dependent and micellar solubilization models

    34-43页
    查看更多>>摘要：Biological solubility is one of the important basic parameters in the development process of poorly soluble drugs,but the current measurement methods are mainly based on a large number of experi-ments,which are time-consuming and cost-intensive.There is still a lack of effective theoretical models to accurately describe and predict the biological solubility of drugs to reduce costs.Therefore,in this study,osaprazole and irbesartan were selected as model drugs,and their solubility in solutions con-taining surfactants and biorelevant media was measured experimentally.By calculating the parameters of each component using the perturbed-chain statistical associating fluid theory(PC-SAFT)model,combined with pH-dependent and micellar solubilization models,the thermodynamic phase behavior of the two drugs was successfully modeled,and the predicted results were in good agreement with the experimental values.These results demonstrate that the model combination used provides important basic parameters and theoretical guidance for the development and screening of poorly soluble drugs and related formulations.

    44-52页
    查看更多>>摘要：With the development of hydrogen energy,palladium-based membranes have been widely used in hydrogen separation and purification.However,the poor chemical stability of palladium composite membranes limits their commercial applications.In this study,a zeolite-palladium composite membrane with a sandwich-like structure was obtained by using a TS-1 zeolite film grown on the surface of palladium membrane.The membrane microstructure was characterized by SEM and EDX The effects of the TS-1 film on the hydrogen permeability and stability of palladium composite membrane were investigated in details.Benefited from the protection of the TS-1 zeolite film,the stability of palladium composite membrane was enhanced.The results indicate that the TS-1-Pd composite membrane was stable after eight cycles of the temperature exchange cycles between 773 K and 623 K.Especially,the loss of hydrogen permeance for TS-1-Pd composite membrane was much smaller than that of the pure palladium membrane when the membrane was tested in the presence of C3H6 atmosphere.It indicated that the TS-1-Pd composite membrane had better chemical stability in comparison with pure palladium membrane,owing to its sandwich-like structure.This work provides an efficient way for the deposition of zeolite film on palladium membrane to enhance the membrane stability.

    查看更多>>摘要：Developing multifunctional spiropyran dyes is of particular importance in diverse applications.In the present study,we synthesized two 2,1,3-benzothiadiazole-conjugated spiropyrans(BT-SP-NO2 and BT-SP-NMe2)with distinct substituents.These donor-acceptor-structured spiropyrans exhibited typical twisted intramolecular charge transfer features and strong emissions in low-polarity solvents with fluorescence quantum yields(QYs)of up to 90.7％.Like traditional spiropyrans,the electron-acceptor-substituted BT-SP-NO2 exhibited excellent photochromic behavior under multiple alternating UV-Vis irradiation,while the electron-donor-substituted BT-SP-NMe2 was an acidochromic dye.In addition,the substituent groups distinctly affected the packing modes of these spiropyrans in the solid state.BT-SP-NMe2 showed a much stronger solid-state emission(QY of 59.0％)than BT-SP-NO2.Moreover,these two dyes were utilized as biocompatible probes for the specific light-up imaging of lipid droplets.

    Regulating the oxidation state of Pd to enhance the selective hydrogenation for 5-hydroxymethylfurfural

    Xin LiYue MaXuning WangJianguo Wu...
    60-68页
    查看更多>>摘要：The highly selective hydrogenation of 5-hydroxymethylfurfural to 2,5-dihydroxymethylfuran is an impor-tant reaction in the field of biomass hydrogenation,because it is a bridge between biomass resources and chemical industry.Here,we precisely constructed carbon nitride supported Pd-based catalysts by a simple impregnation-reduction method.By changing the reduction temperature,catalysts with different oxidation state could be precisely constructed.Moreover,the important correlation between the ratio of Pd0/Pd2+and catalytic activity is revealed during the selective hydrogenation of HMF.The Pd/g-C3N4-300 catalyst with a Pd0/Pd2+ratio of 3/2 showed the highest catalytic activity,which could get 96.9％5-hydroxymethylfurfural conversion and 90.3％2,5-dihydroxymethylfuran selectivity.Further density functional theory calculation revealed that the synergistic effect between Pd0 and Pd2+in Pd/g-C3N4-300 system could boost the adsorption of the substrate and the dissociation of hydrogen.In this work,we highlight the important correlation between metal oxidation state and catalytic activity,which provides valuable insights for the rational design of precious metal catalysts for hydrogenation reactions.

    69-73页
    查看更多>>摘要：Preferential orientation control of metal-organic framework(MOF)films is advantageous for maxi-mizing pore uniformity and minimizing grain-boundary defects.Nonetheless,the preparation of MOF films with both in-plane and out-of-plane orientations remains a grand challenge.In this study,we reported the preparation of three-dimensionally oriented MIL-96 layers through combining morphology control of MIL-96 seeds with addition of polyvinylpyrrolidone surfactants and arachidonic acids.The three-dimensionally oriented MIL-96 film was readily obtained through in-plane epitaxial growth.It is anticipated that the aforementioned protocol can be effective for obtaining diverse MOF films with a three-dimensionally oriented organization.

    74-84页
    查看更多>>摘要：Spinning disk reactor(SDR)has emerged as a novel process intensification photocatalytic reactor,and it has higher mass transfer efficiency and photon utilization for the degradation of toxic organic pollutants by advanced oxidation processes(AOPs).In this study,ZnO-TiO2 nanocomposites were prepared by sol-gel method,and coated on the disk of SDR by impregnation-pull-drying-calcination method.The per-formance of catalyst was characterized by X-ray diffraction,scanning electron microscope,X-ray photoelectron spectroscopy,photoluminescence and ultraviolet-visible diffuse reflectance spectroscopy.Photocatalytic ozonation in SDR was used to remove phenol,and various factors on degradation effect were studied in detail.The results showed that the rate of degradation and mineralization reached 100％and 83.4％under UV light irradiation after 50 min,compared with photocatalysis and ozonation,the removal rate increased by 69.3％and 34.7％,and mineralization rate increased by 56.7％and 62.9％,which indicated that the coupling of photocatalysis and ozonation had a synergistic effect.The radical capture experiments demonstrated that the active species such as photogenerated holes(h+),hydroxyl radicals(OH),superoxide radical(·O2-)were responsible for phenol degradation,and OH played a leading role in the degradation process,while h+and·O2-played a non-leading role.
