PEO-based all-solid-state electrolytes are extensively utilized and researched owing to their exceptional safety,low-mass-density,and cost-effectiveness.However,the low oxidation potential of PEO makes the interface problem with the high-voltage cathode extremely severe.In this work,the impedance of PEO-based all-solid-state batteries with high-voltage cathode(NCM811)was studied at different potentials.The Nyquist plots displayed a gyrate arc at low-frequencies for NCM811/PEO interface.Based on the kinetic modeling,it was deduced that there is a decomposition reaction of PEO-matrix in addition to de-embedded reaction of NCM811,and the PEO intermediate product(dehydra-PEO)adsorbed on the electrode surface leading to low-frequency inductive arcs.Furthermore,the distribution of relaxation time shows the dehydra-PEO results in the kinetic tardiness of the charge transfer process in the temporal dimension.Hence,an artificial interface layer(CEI_(x))was modified on the surface of NCM811 to regulate the potential of cathode/electrolyte interface to prevent the high-voltage deterioration of PEO.NCM/CEI_(x)/PEO batteries exhibit capacity retentions of 96.0%,84.6%,and 76.8%after undergoing 100 cycles at cut-off voltages of 4.1,4.2,and 4.3 V,respectively.Therefore,here the failure mechanism of high-voltage PEO electrolyte is investigated by EIS and a proposed solving strategy is presented. 展开更多

Background:Baoyuan decoction is used clinically as an adjuvant treatment for lung cancer.However,the underlying mechanism remains unclear.Therefore,this study aimed to explore the mechanism of action of Baoyuan decoction in lung cancer treatment using network pharmacology and molecular docking technology.Methods:The Traditional Chinese Medicines Systems Pharmacology Database and Analysis Platform and SwissTargetPrediction databases were used to screen the active ingredients of Baoyuan decoction and their relevant targets.Lung cancer-related targets were obtained from the GeneCards,Online Mendelian Inheritance in Man,and DrugBank databases.Protein-protein interaction network of the common targets was constructed using the STRING database and analyzed using Cytoscape software 3.10.1.Furthermore,Gene Ontology enrichment,Kyoto Encyclopedia of Genes and Genomes pathway analyses and visualization of common genes were performed using the R software.Finally,molecular docking of the selected key ingredients and targets was performed,and the results were verified using AutoDock Vina software.Results:We identified 142 potential active ingredients,3624 potential lung cancer-related targets,and 341 common drug targets.A total of 72 core targets were identified,of which AKT1,TP53,interleukin-6,epithelial growth factor receptor,and signal transducer and activator of transcription 3 were key.A total of 4116 items were obtained via Gene Ontology enrichment analyses.Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses revealed 189 related signaling pathways,including the PI3K-Akt,AGE-RAGE signaling pathways in diabetic complications,FOXO,and TH signaling pathways,which are involved in cell proliferation,autophagy,metastasis,invasion,radiation resistance,and chemotherapy resistance in the lung cancer microenvironment.The molecular docking results suggested that the key ingredients had a strong affinity for key targets.Conclusion:This study demonstrates that Baoyuan decoction plays a key therapeutic role in a complex manner involving multiple ingredients,targets,and pathways in lung cancer.Our findings are anticipated to provide new ideas for follow-up experimental research and clinical application. 展开更多

The penetration behavior of topical substances in the skin not only relates to the transdermal delivery efficiency but also involves the safety and therapeutic effect of topical products,such as sunscreen and hair growth products.Researchers have tried to illustrate the transdermal process with diversified theories and technologies.Directly observing the distribution of topical substances on skin by characteristic imaging is the most convincing approach.Unfortunately,fluorescence labeling imaging,which is commonly used in biochemical research,is limited for transdermal research for most topical substances with a molecular mass less than 500 Da.Label-free imaging technologies possess the advantages of not requiring any macromolecular dyes,no tissue destruction and an extensive substance detection capability,which has enabled rapid development of such technologies in recent years and their introduction to biological tissue analysis,such as skin samples.Through the specific identification of topical substances and endogenous tissue components,label-free imaging technologies can provide abundant tissue distribution information,enrich theoretical and practical guidance for transdermal drug delivery systems.In this review,we expound the mechanisms and applications of the most popular label-free imaging technologies in transdermal research at present,compare their advantages and disadvantages,and forecast development prospects. 展开更多

Combined with the experimental results from the large tunnel of the ChongqingResearch Institute,the mechanism of gas and coal dust explosion was studied.Someconcepts about gas and coal dust explosion were introduced such as the form conditionand influential factors.Gas and coal dust explosion propagation was researched and thelifting process of coal dust was simulated.When an explosion occurred due to great mixtureof gas and air,the maximum explosion pressure appeared in the neighborhood of theexplosion source point.Before it propagated to the tunnel of the deposited coal dust,themaximum explosion pressure appeared to be in declining trend.Part of the energy waslost in the process of raising the deposited coal dust through a shock wave,so the maximumexplosion pressure was smallest on the foreside of the deposited coal dust sector.On the deposited coal dust sector,the explosion pressure rapidly increased and droppedoff after achieving the largest peak value.Because of coal dust participation in the explosion,the flame velocity rose rapidly on the deposited coal dust and achieved a basic stablevalue;coal dust was ignited to explode by initial laminar flame,and the laminar flametransformed into turbulent flame.The turbulence transformed the flame fold into a funnelshape and the shock wave interacted with the flame,so the combustion rate rose and thepressure wave was further enhanced.The regeneration mechanism between the flamecombustion rate and the aerodynamic flowing structure achieved the final critical state forforming the detonation. 展开更多

Objective:To investigate the active compounds,key targets and molecular mechanism of Qizhu Yuling Decoction in the treatment of esophageal carcinoma based on network pharmacology.Methods:The active compounds of Qizhu Yuling Decoction with anti-esophageal cancer activity were screened by TCMSP and literature search,and the drug targets were searched by DrugBank and predicted by SwissTargetPrediction.The esophageal cancer-related genes were obtained from GeneCards,OMIM,DrugBank,TTD,DisGeNET,and the intersection network was selected to obtain candidate genes.The"herb-compound-target-disease"network was constructed with Cytoscape,the PPI network was constructed in STRING and core network modules were screened.Gene ontology and KEGG enrichment analysis was performed by using Metascape,and the"pathway-gene"network was constructed to further screen key targets.Results:A total of 47 active compounds(19 Astragalus,4 Zedoary turmeric,11 Atractylodes macrocephala,9 Curcuma longa,5 Clematis root,and 5 Salvia chinensis),297 candidate genes,2413 GO and 119 KEGG pathways were obtained.Conclusion:The active compounds of Qizhu Yuling Decoction in the treatment of esophageal cancer are quercetin,kaempferol,glycine and ursolic acid.The potential targets are AKT1,MAPK1,MAPK3,PIK3R1 and RELA.GO involves oxidative stress,cell cycle,apoptosis and cell death,and KEGG involves typical cancer pathways,MAPK,NF-κB and PI3K-Akt signaling pathways.This study reveals the molecular biological mechanism of Qizhu Yuling Decoction in the treatment of esophageal cancer,and speculates that the function of potential targets focuses on the interaction of multiple signaling pathways,which can antagonize the proliferation,invasion,metastasis and recurrence of esophageal cancer and improve the prognosis of patients.This study provides new evidence for subsequent new drug development,clinical application and experimental study. 展开更多

It is charac-terized by two nuclear columns which distinguish it from uninuclcus-type vorlex structure. The vortical sur-faces of the structure are commonly s-shaped and reversed s-shaped and subordinately of clliptic andhyperbolic shape. and sometimes turbine-like surfaces are observed. On the basis of field structural studies. a mechanical model of rotation around a binuclear column ofcrustal materials is presented in the paper. Burgers viscoelastic solutions of the stress field and deformationfield of this structural type have been obtained using the principle and method of rheology. and simulation ex-periments have been performed. The results of the theoretical calculation and experiments indicate that theproposed mechanical model is applicable. 展开更多

In this paper,research of aftershock mechanisms is reviewed,including heterogeneity of medium and stress,mechanical loading,fluid intrusion and stress corrosion,and ratestate dependence.Previous studies have indicated that the heterogeneity of media and stress is the basic premise of aftershocks generated.From the point view of mechanics,transient creep and afterslip can explain the decay of aftershocks in a short time after a mainshock and the relaxation of stress tends to interpret the characteristics of long-term aftershocks.Fluid intrusion and stress corrosion control the evolution process of the aftershocks under certain conditions.The interaction between the faults perturbed by the mainshock always exists during the aftershock activities.All kinds of models and the theories want to comply with the two basic power-law relationships---the G-R law and Omori law to some extent. 展开更多

A new kind of cutting movement trajectory is gi ven whose actual cutting efficiency is near to 100%. It can reduce the energy w earing greatly, and the surface quality of the product is improved to the utmost extent. The design mechanism of the optimal cutting movement trajectory system structure is analyzed incisively. At the same time, the principle of the complex movement of horizontal movement and swing is researched. The optimal design scheme of th e cutting movement trajectory system structure is set up. The choice method to g et the superior value of the movement system structure is found. The mathematics function formula is established which exhibits the relationship between the par ameter of the complex movement structure and that of the system movement structu re. By the formula, the precision value of the offset can be figured out. The r ule is adapted to different types of energy-saving stone-sawing machines. The complex movement structure of horizontal movement and swing is designed to f ulfill the cutting movement. It can make the saw frame move up with the hanging pod deviating from the vertical direction. At the same time, the saw frame have a down-movement. Then the sum of the two movements is near to zero, and the saw blade and the stone can keep in touch during the whole horizontal cutting. The result is that the actual cutting efficiency is 100%. Also, when the hanging pod moves to the limited position, the saw frame can keep the original inertia, and continue to swing up. It makes the back-cutting have high energy-storing. The optimal design of the eccentricity balance wheel is done. The mathematics fo rmula for expressing the movement system structure is deduced. The calculation m ethod and formula is set up which is used to get the value of important componen ts such as offset. The choice method and formula of elasticity distortion coeffi cient is set up when the saw frame moves smoothly. It is concluded that the offs et is the key dimension to actualize the optimal cutting movement trajectory. The resolving of the technical problems discussed above offers a theoretic and technical basis for optimal design of energy-saving stone-sawing machines. 展开更多

An accumulation of previous work has established organoids as good preclinical models of human tumors,facilitating translation from basic research to clinical practice.They are changing the paradigm of preclinical cancer research because they can recapitulate the heterogeneity and pathophysiology of human cancers and more closely approximate the complex tissue environment and structure found in clinical tumors than in vitro cell lines and animal models.However,the potential applications of cancer organoids remain to be comprehensively summarized.In the review,we firstly describe what is currently known about cancer organoid culture and then discuss in depth the basic mechanisms,including tumorigenesis and tumor metastasis,and describe recent advances in patient-derived tumor organoids(PDOs)for drug screening and immunological studies.Finally,the present challenges faced by organoid technology in clinical practice and its prospects are discussed.This review highlights that organoids may offer a novel therapeutic strategy for cancer research. 展开更多

The electrocatalytic sulfur reduction reaction(SRR)and sulfur evolution reaction(SER),two fundamental multistep conversion processes in lithium–sulfur batteries(LSBs),are root-cause solutions to overcome sluggish redox kinetics and the polysulfide shuttling effect.Metal–organic framework(MOF)electrocatalysts have emerged as good platforms for catalyzing SRR and SER,but their catalytic performance is challenged by poor electrical conductivity and limited chemical stability.Functionalized MOFs and their hybrids may be beneficial for stabilizing and improving the desired catalytic properties to achieve high-performance LSBs.This review provides a detailed overview of engineering principles for improving the activity,selectivity,and stability of MOFrelated electrocatalysts via composition modulation and nanostructure design as well as hybrid assembly.It presents and discusses the various advances achieved by using in situ characterization techniques,simulations,and theoretical calculations to reveal the dynamic evolution of MOF-related electrocatalysts,enabling an in-depth understanding of the catalysis mechanism at the molecular/atomic level.Lastly,prospects and possible research directions for MOF-related sulfur electrocatalysts are proposed. 展开更多
