An approach combining the plasma nitriding with lubrication additive is proposed to improve the durability of the antifriction bearing.The nitrided layer on GCr15 steel is prepared in a plasma nitriding furnace.Its surface morphologies,phase structure,and hardness are analyzed by means of scanning electron microscope(…
Cohesive zone models are versatile and effective tools for computational simulation of various separation phenomena in materials. We welcome papers that present theory and applications of cohesive zone models at any length and time scales, from atomistic and molecular to microstructural and phenomenological models. Th…
To improve accuracy of calculating the static contact angle of hydrophilic materials,we proposed a static contact angle algorithm considering globule volume and hydrophobicity.The globule edge curve was generated by the Young-Laplace equation,in the meantime,noise was superimposed to the curve to simulate the error of…
Dichlorophenylphosphine was synthesized from benzene and phosphorous trichloride with Zn/HZSM-5 as catalyst in the vapor phase through a fixed-bed reactor.Factors,like zinc content,molar ratio of raw materials,reaction temperature and time were investigated.The results showed when using the catalyst of Zn/HZSM-5 with…
Plain velvet fabric considered as a high-grade face fabric is easy to be lodged after the fabric is used, affecting fabric’sappearance. Combined the features of knitted velvet fabric with woven high-pile fabric, this paper presents the method to produceno-lodging-pile plain velvet fabric by woving technology with key…
The self-organization and nano-segregation of small functional molecules are useful tools for designing and preparing new functional supramolecular materials.Assembly directed by hydrogen bonding is widely used to prepare supramolecular materials.As an electronic acceptor,triazine is a useful tecton for formation of H…
The process of untwisted yarn and untwisted fabric,as well as the note of production were introduced.Some kinds of performance of seven different fabrics were tested and analyzed,the analysis showed that the untwisted fabric product had the characteristics of fluffy and soft feeling,godd water absorbability and water…
This paper aims to study the stress relaxation properties of thin wood composites based on the theory of cantilever-beam bending.According to the stress relaxation tests,we found that this detection method was feasible.From the stress graph and test data of stress relaxation properties,it was found that the attenuatio…
This paper carries out a study on the preparation of polyvinylamine(PVAm) by method of Hofmann degradation.The material ratio,reaction temperature,addition mode and other reaction conditions which affect amination degree were discussed,and the recycle of the mixed solution containing alcohol and base was studied.The r…
In this paper,a flexible thioether ligand 3,4-bis(2-pyrimidinesulfanylmethyl) thiophene(L) has been prepared.On the basis of the self-assembly of AgClO4 and L,the(4,4)network coordination polymer,[Ag(L)ClO4]n.nH2O(1) has been synthesized and characterized by X-ray crystallography and IR.Single-crystal X-ray diffractio…
Cobaltosic oxide(Co3O4) was prepared by solvent-thermal method,then polyaniline(PANI)-Co3O4 composite was prepared by chemical in-situ polymerization using manganese dioxide(MnO2) as oxidant.The product was analyzed by SEM,XRD,cyclic voltammetry and galvanostatic charge-discharge tests.Co3O4 was cubic crystal,covered…
The super-hydrophobic films on Zinc(Zn) substrate were fabricated by a simple two-step process.Firstly,nano-structured film was created to roughen Zn surface by solution oxidation process in the presence of N,N,-dimethylformamide(DMF).Resultant roughened Zn surface was then overcoated with stearic acid to achieve supe…
The fracture behavior of PE-HD/wollastonite/POE-g-MAH composites in the mixed mode region was studied using the essential work of fracture(EWF) method.The applicability of EWF method and the stress state of the samples were verified.Linear regression was used on the experimental data to obtain the EWF parameters.With…
The Ru-doping La0.7Ca0.2Ba0.1Mn1-xRuxO3(x=0~0.06) polycrystalline samples have been prepared by solid state reaction method.The influence of Ru-doping on the structure,transport properties and magnetoresistance have been investigated.X-ray diffraction indicated that all the samples are of simple cubic perovskite struc…
The proper height iron-core were combined by single core,which were prepared by the low width homemade amorphous alloy ribbons.And then they were incised by line incise.The lancing morphology,structure of the amorphous alloy core were examined,and magnetic properties of cores before and after incised at the power freq…
ATP-binding cassette(ABC)transporters are important selective elements of the blood-brain barrier.They both protect the central nervous system from entry of neurotoxicants and limit the access of therapeutic drugs to the brain parenchyma.Recent studies highlighted the multiple signaling pathways through which the expr…
By using the ZnO with the purity of 99.9% and the mass fraction of 98%,the ceramic target of 2% Al2O3 as the sputtering target material,the Al2O3-dopping ZnO film was prepared on the glass substrate pre-deposited ZnO and Al2O3 by the magnetic sputtering method.The effect of two different ZnO and Al2O3 buffer layers on…
