All‑Covalent Organic Framework Nanofilms Assembled Lithium‑Ion Capacitor to Solve the Imbalanced Charge Storage Kinetics

Free-standing covalent organic framework(COFs)nanofilms exhibit a remarkable ability to rapidly intercalate/de-intercalate Li^(+) in lithium-ion batteries,while simultaneously exposing affluent active sites in supercapacitors.The development of these nanofilms offers a promising solution to address the persistent challenge of imbalanced charge storage kinetics between battery-type anode and capacitor-type cathode in lithium-ion capacitors(LICs).Herein,for the first time,custom-made COFBTMB-TP and COFTAPB-BPY nanofilms are synthesized as the anode and cathode,respectively,for an all-COF nanofilm-structured LIC.The COFBTMB-TP nanofilm with strong electronegative–CF3 groups enables tuning the partial electron cloud density for Li^(+) migration to ensure the rapid anode kinetic process.The thickness-regulated cathodic COFTAPB-BPY nanofilm can fit the anodic COF nanofilm in the capacity.Due to the aligned 1D channel,2D aromatic skeleton and accessible active sites of COF nanofilms,the whole COFTAPB-BPY//COFBTMB-TP LIC demonstrates a high energy density of 318 mWh cm^(−3) at a high-power density of 6 W cm^(−3),excellent rate capability,good cycle stability with the capacity retention rate of 77%after 5000-cycle.The COFTAPB-BPY//COFBTMB-TP LIC represents a new benchmark for currently reported film-type LICs and even film-type supercapacitors.After being comprehensively explored via ex situ XPS,7Li solid-state NMR analyses,and DFT calculation,it is found that the COFBTMB-TP nanofilm facilitates the reversible conversion of semi-ionic to ionic C–F bonds during lithium storage.COFBTMB-TP exhibits a strong interaction with Li^(+) due to the C–F,C=O,and C–N bonds,facilitating Li^(+) desolation and absorption from the electrolyte.This work addresses the challenge of imbalanced charge storage kinetics and capacity between the anode and cathode and also pave the way for future miniaturized and wearable LIC devices.

Hydrocarbon gas huff-n-puff optimization of multiple horizontal wells with complex fracture networks in the M unconventional reservoir

The oil production of the multi-fractured horizontal wells(MFHWs) declines quickly in unconventional oil reservoirs due to the fast depletion of natural energy. Gas injection has been acknowledged as an effective method to improve oil recovery factor from unconventional oil reservoirs. Hydrocarbon gas huff-n-puff becomes preferable when the CO_(2) source is limited. However, the impact of complex fracture networks and well interference on the EOR performance of multiple MFHWs is still unclear. The optimal gas huff-n-puff parameters are significant for enhancing oil recovery. This work aims to optimize the hydrocarbon gas injection and production parameters for multiple MFHWs with complex fracture networks in unconventional oil reservoirs. Firstly, the numerical model based on unstructured grids is developed to characterize the complex fracture networks and capture the dynamic fracture features.Secondly, the PVT phase behavior simulation was carried out to provide the fluid model for numerical simulation. Thirdly, the optimal parameters for hydrocarbon gas huff-n-puff were obtained. Finally, the dominant factors of hydrocarbon gas huff-n-puff under complex fracture networks are obtained by fuzzy mathematical method. Results reveal that the current pressure of hydrocarbon gas injection can achieve miscible displacement. The optimal injection and production parameters are obtained by single-factor analysis to analyze the effect of individual parameter. Gas injection time is the dominant factor of hydrocarbon gas huff-n-puff in unconventional oil reservoirs with complex fracture networks. This work can offer engineers guidance for hydrocarbon gas huff-n-puff of multiple MFHWs considering the complex fracture networks.

Effect of Mn content on microstructure and properties of AlCrCuFeMnx high-entropy alloy

AlCrCuFeMnx(x=0,0.5,1,1.5,and 2)high-entropy alloys were prepared using the vacuum arc melting technology.The microstructure and mechanical properties of AlCrCuFeMnxwere analyzed and tested by XRD,SEM,TEM,nanoindentation,and electronic universal testing.The results indicate that the AlCrCuFeMnxhigh-entropy alloy exhibits a dendritic structure,consisting of dendrites with a BCC structure,interdendrite regions with an FCC structure,and precipitates with an ordered BCC structure that form within the dendrite.Manganese(Mn)has a strong affinity for dendritic,interdendritic,and precipitate structures,allowing it to easily enter these areas.With an increase in Mn content,the size of the precipitated nanoparticles in the dendritic region initially increases and then decreases.Similarly,the area fraction initially decreases and then increases.Additionally,the alloy’s strength and wear resistance decrease,while its plasticity increases.The Al Cr Cu Fe Mn1.5alloy boasts excellent mechanical properties,including a hardness of 360 HV and a wear rate of 2.4×10^(-5)mm^(3)·N^(-1)·mm^(-1).It also exhibits impressive yield strength,compressive strength,and deformation rates of 960 MPa,1,700 MPa,and 27.5%,respectively.

Unlocking epigenetics for precision treatment of Ewing’s sarcoma

Ewing’s sarcoma(EWS)is a highly aggressive malignant bone tumor primarily affecting adolescents and young adults.Despite the efficacy of chemoradiotherapy in some cases,the cure rate for patients with metastatic and recurrent disease remains low.Therefore,there is an urgent need for innovative therapeutic approaches to address the challenges associated with EWS treatment.Epigenetic regulation,a crucial factor in physiological processes,plays a significant role in controlling cell proliferation,maintaining gene integrity,and regulating transcription.Recent studies highlight the importance of abnormal epigenetic regulation in the initiation and progression of EWS.A comprehensive understanding of the intricate interactions between EWS and aberrant epigenetic regulation is essential for advancing clinical drug development.This review aims to provide a comprehensive overview of both epigenetic targets implicated in EWS,integrating various therapeutic modalities to offer innovative perspectives for the clinical diagnosis and treatment of EWS.

Interferon-gamma regulates the progression of neuroblastoma cells through interferon-regulatory factor-1

Objective:This study aimed to elucidate the influence of IFN-gamma(IFN-γ)in neuroblastoma(NB)cells and reveal its potential underlying molecular mechanism.Methods:The Cell Counting Kit-8,Transwell apparatus,and flow cytometry were employed to assess cellular viability,migratory capacity,invasive potential,and apoptotic rates,respectively.RNA-seq combined with bioinformatics analysis revealed differentially expressed genes(DEGs)and their possible biological functions.Protein levels were determined by western blot analysis.Results:IFN-γtreatment resulted in diminished cell viability,mitigated migratory and invasive capabilities,and augmented apoptotic activity in the SK-N-BE(2)cell line,whereas it exhibited the opposite effect in SH-SY5Y cells.Furthermore,interferon regulatory factor 1(IRF-1)was the common DEG in both IFN-γ-treated SK-N-BE(2)and SH-SY5Y cells.Additionally,we found that it was underexpressed in NB tissues.The depletion of IRF-1 promoted the progression of both SK-N-BE(2)and SH-SY5Y cells.Moreover,IRF-1 knockdown effectively counteracted the effects of IFN-γon SK-N-BE(2)cells,while exacerbating them in SH-SY5Y cells.Conclusion:This study verified that IFN-γexerted a distinct role in both N-Myc-and non-N-Myc-amplified NB cells,partially by mediating the expression of IRF-1,suggesting that it may serve as a potent agent for treating patients with NB.

A review of the development of asphalt foaming technology

To comprehensively assess the current state-of-art in asphalt foaming technology, the following four key aspectshave been reviewed systematically: foaming principles, test methods, evaluation indicators, and influencing factors.Key findings reveal that asphalt foaming was primarily driven by the vaporization of water, with deteriorationprocesses including bubble collapse and liquid film drainage. However, the current understanding of asphaltfoaming principles remains limited, primarily due to difficulties in capturing and precisely measuring its microscopic behaviors during asphalt foaming process. Volume changes provided an intuitive means to evaluate theexpansion capacity of asphalt and its foaming stability. Bubble evolution characteristics of foamed asphalt offeredpromising insights into its foaming performance. Traditional ruler and stopwatch-based assessments were beingsuperseded by automated techniques like laser and ultrasonic ranging. Nevertheless, the current measuringequipment still lacks the capability to comprehensively evaluate the foaming effect of asphalt across various dimensions. Asphalt temperature and foaming water consumption significantly affected asphalt foaming performance, and the inclusion of foaming agents typically led to a notable increase in the half life of foamed asphalt.However, the interaction between foaming agents and asphalt, as well as the underlying mechanisms affecting thefoaming effect, are still unclear and require further exploration. Future research should primarily focus on thecorrelation between asphalt foaming effect and mixture performance, aiming to guide the practical engineeringapplication of foamed asphalt mixtures and enlarge the advantages of such low-emission and sustainable mixtures.

Natural regulatory T cells and bifunctional regulatory T cells:potential targets of traditional Chinese medicine in treating colitis-associated colon cancer

Colon cancer(CRC)is one of the most common malignancies globally,ranking third in terms of new cancer cases and second as a cause of cancer deaths[1].In recent 30 years,the incidence and mortality rates of CRC in China have been increasing,gradually exceeding the global levels[2].Due to the fact that most CRC patients are diagnosed at the advanced stage,the treatment of this disease is challenging and often ineffective.Therefore,prevention and early diagnosis of CRC are crucial.

Objective:To investigate the effects of Jiangan Xiaozhi Formula(JGXZ)on oxidative stress and inflammatory factors in patients with non-alcoholic fatty liver disease(NAFLD).Methods:Between September 2022 and December 2023,our hospital admitted a total of 58 patients with NAFLD.These patients were split into two groups at random:one for experimentation and the other for control.There were 27 patients in the experimental group at the end,compared to 26 in the control group,reasonable exercise,weight management,lipid regulation,and oral polyene phosphatidylcholine capsules(PPC).The experimental group received JGXZ in addition to the above treatments for 12 consecutive weeks.Changes in Traditional Chinese Medicine(TCM)syndrome scores,blood lipids,liver function indicators,the levels of oxidative stress markers,such as malondialdehyde(MDA),glutathione peroxidase(GSH-Px),and superoxide dismutase(SOD),as well as serum inflammatory factors,such as interleukin-6(IL-6),interleukin-8(IL-8),and tumor necrosis factor-α(TNF-α),were measured both before and after treatment.Results:After treatment,both groups showed significant reductions in TCM syndrome scores(P<0.05)and improvements in blood lipids,liver function indicators,inflammatory factors,and oxidative stress markers(P<0.05).Improvements were noticeably better in the experimental group than in the control group.(P<0.05).Conclusion:JGXZ can significantly improve clinical symptoms,regulate blood lipids,and protect liver function in patients with NAFLD.Its mechanism may be related to inhibiting inflammatory responses and regulating the balance of the oxidation-antioxidation system.

From rectangle to parallelogram:an area-weighted method to make time-space diagrams incorporate traffic waves

A time-space(TS)traffic diagram is one of the most important tools for traffic visualization and analysis.Recently,it has been empirically shown that using parallelogram cells to construct a TS diagram outperforms using rectangular cells due to its incorporation of traffic wave speed.However,it is not realistic to immediately change the fundamental method of TS diagram construction that has been well embedded in various systems.To quickly make the existing TS diagram incorporate traffic wave speed and exhibit more realistic traffic patterns,the paper proposes an area-weighted transformation method that directly transforms rectangular-cell-based TS(rTS)diagrams into parallelogram-cell-based TS(pTS)diagrams,avoiding tracing back the raw data of speed to make the transformation.Two five-hour trajectory datasets from Japanese highway segments are used to demonstrate the effectiveness of the proposed methods.The travel time-based comparison involves assessing the disparities between actual travel times and those computed using rTS diagrams,as well as travel times derived directly from pTS diagrams based on rTS diagrams.The results show that travel times calculated from pTS diagrams converted from rTS diagrams are closer to the actual values,especially in congested conditions,demonstrating superior performance in parallelogram representation.The proposed transformation method has promising prospects for practical applications,making the widely-existing TS diagrams show more realistic traffic patterns.

Modulating the crosstalk between macrophage and Th17: potential mechanism of natural products on acute lung injury

Sepsis is a life-threatening multiple organ dysfunction syndrome caused by the imbalance of the immune response to infection,featuring complex and variable conditions,and is one of the leading causes of mortality in ICU patients.Lung injury is a common organ damage observed in sepsis patients.Macrophages and Th17 cells,as crucial components of innate and adaptive immunity,play pivotal roles in the development of sepsis-induced acute lung injury(ALI).This review summarizes the alterations and mechanisms of macrophages and Th17 cells in sepsis-induced ALI.By focusing on the“cross-talk”between macrophages and Th17 cells,this review aims to provide a solid theoretical foundation for further exploring the therapeutic targets of traditional Chinese medicine formulas in the treatment of sepsis complicated with ALI,thereby offering insights and guidance for the clinical application of traditional Chinese medicine in managing sepsis-associated ALI.

Changes of mitochondrial dynamics during the progression of non-alcoholic fatty liver disease: a review

Non-alcoholic fatty liver disease(NAFLD)is a chronic liver disease closely related to metabolic disorders that pose a serious threat to human health.Currently,no specific drugs are available for treating the aetiology of NAFLD in clinical practice.Mitochondria have various biological functions inside the cell.Studies have found that mitochondrial fission and fusion are closely related to NAFLD.Therefore,identifying therapeutic targets for NAFLD through mitochondrial fission and fusion is crucial.Particularly in the field of traditional Chinese medicine,good therapeutic effects have been achieved in the treatment of NAFLD by protecting mitochondrial fusion and fission.Therefore,this article reviews the relationship between mitochondrial dynamics and NAFLD as well as the treatment of NAFLD through the regulation of mitochondrial fission and fusion with traditional Chinese medicine to provide a reference for the clinical application of traditional Chinese medicine in regulating mitochondrial fission and fusion functions to treat NAFLD.

The relationship between ferroptosis and non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease(NAFLD)is a kind of metabolic disorder characterized by excessive fat deposition in the liver and ranging from simple steatosis(simple NAFLD)to nonalcoholic steatohepatitis(NASH),cirrhosis,and hepatocellular carcinoma[1].It has recently been increasing annually;for example,it was recently estimated to have a global prevalence of 32.4%,which seriously threatens human health[2].Thus,the discovery of new therapeutic targets is of great importance because there is no specified drug for the treatment of NAFLD.On the other hand,the pathogenesis of NAFLD is complicated and still unclear.Recent studies have proposed ferroptosis as related to the disease progressions of NAFLD.Preliminary evidence indicated that ferroptosis in hepatocytes and hepatic macrophages could induce NASH and that complex regulatory mechanisms were involved.In the future,inhibition of ferroptosis may hopefully become an emerging target in treating NAFLD.
