Here we report the development of Poly Urethane (PU)/ graphene oxide composite used as the scaffold of anterior cruciate ligament tissue engineering. The influences of the GO on the composite were studied by FTIR, SEM and XRD. The Youngs modulus of the composite is 30.6 MPa compared to that of PU`s 6.8 MPa. The GO ind…
The competitive precipitation behavior between T1 and σ phases in Al-Cu-Li alloy was studied by hardness test, XRD and TEM observation. The hardness test results show that the changing curves are related to the densities of vacancies and dislocations, and competitive precipitation between age hardening precipitates. T…
Porous titanium dioxide (TiO2) nanostructure has been successfully synthesized by a modified solgel method using non-ionic triblock copolymer pluronic F-127 as surfactant template and titanylsulfate (TiOSO4) solution as the inorganic precursor derived from the sulfuric process of Bangka-Indonesia ilmenite ore. The res…
For electric magnetic system which contains permanent magnet, its calculation results often has a low level accuracy when using equivalent circuit method .The calculation method of permanent magnet leakage permeance is the key point and needs to be improved. The leakage permeance calculation formulas of bar type perma…
In this work, the effect of isothermal heat treatments on microstructure evolution and mechanical properties after welding by induction of A37 pipeline steel have been studied by scanning electron microscopy, hardness measurements, and tensile tests. Microstructural evolution in welded joint was identified after isoth…
Metronomic chemotherapy supports the idea that long-term administration of chemotherapeutics could be effective against numerous cancers. On page 230, Alessandro Grattoni and colleagues present constant and sustained release of ultrastable drug-loaded liposomes from an implantable nanochannel delivery system over 18 d…
Ferromagnetic resonance in planar arrays of iron nanowires (NW) covered with a layer of MgO is studied as a function of aging time. Planar arrays of iron NW are grown on stepped vicinal surfaces of oxidized Si (111) substrates by low-angle molecular beam epitaxy. The ferromagnetic resonance measurements reveal a perpe…
In order to solve the problem that the big loss of no-load and the fast rise of temperature when employ the conventional silicon steel metal transformer (SSMT) in the electric heating system, we choose the amorphous metal transformer (AMMT). In this paper, firstly, we give a brief introduction of the amorphous alloy m…
As one of the quenched and tempered steels, 40Cr steel is often used to manufacture the shaft in heavy-duty trucks. To adjust the working environment of the heavy-duty machines, 40Cr steel should have high impact property. In this study, different tempering cooling mediums were treated as critical influence on improvi…
ZnO films were deposited on Si (100) substrates by using a two-step growth process. In the first step, ZnO nanorods were grown by using the hydrothermal method at 140 °C for 5 min. In the second step, a ZnO amorphous layer was deposited on the ZnO nanorods by spin-coating. After completion of the growth process, the f…
The wafer carrier is made of PP, PC, PE resin which have excellent heat and chemical resistance and electrical properties. However, particle generation has become a problem due to static electricity generated in the carrier. Some conductive material such as carbon black (CB) and carbon fiber (CF) are added for the pur…
A physical model of magnetron sputtering process was built, the distribution of MgO film thickness on the substrate was deduced, and the data were analyzed by using the Matlab. nanosized MgO thin film was prepared on Si substrate by magnetron sputtering. SGC-10 was used to measure the thickness of MgO thin film. The r…
Pure anatase, pure rutile and the mixed TiO2 crystals with different amounts of rutile and anatase were prepared by a hydrothermal method using Ti (OBu)4 as starting material. The effect of anions on crystal phase and morphology of TiO2 synthesized by the hydrothermal method was investigated, and the relevant mechanis…
The radiation shielding abilities of functional particles (Sm2O3, Er2O3, WO3and Bi2O3) were simulated and proved to have a stronger absorption region and a weaker absorption region respectively. Four kinds of functional particles/epoxy radiation shielding composites used for low energy γ/Xray were designed based on th…
Porous silicon (PSi) was fabricated by using electrochemical anodic etching method. Then acid treatment and cathode reduction treatment were employed to improve the luminescence properties and stability of PSi material. Photoluminescence (PL) measurements and scanning electron microscope (SEM) were used to observe the…
단일 노즐을 이용하는 CO₂ 포집용 분무탑의 기본적 특성을 실험적으로 구하였다. 다양한 조건 - 주입 기체 유량 및 농도, 주입 흡수제 유량 및 농도 등 - 에서 얻어진 포집성능을 포집효율 뿐만 아니라 재생에너지의 주요 결정요인인 CO₂ 포화도 측면에서 검토하였다. 다양한 조건들에서의 포집효율 변화는 흡수제(NH₃)와 CO₂ 의 상대적 유량비만의 단조증가함수로 잘 표현되었다. 포집후의 흡수제의 CO₂ 포화도 또한 NH₃/CO₂ 유량비만의 함수로 잘 정리가 되었으나, 포집효율과는 다르게 단조감소함수를 보였으며, 특히 CO₂ 포화도와 포집효율과의 상관관계를 보면 기존의…
The optimization problem for finding the global minimum energy structure is one of the main problems of protein structure prediction and is known to be an NP-hard problem in computational molecular biology. The low-energy conformational search problem in the hydrophobic-hydrophilic-neutral (BLN) off-lattice model is s…

The flowing stress of a highstrength steel before unloading is different with the yield stress of the same sample extended in air after unloading and charging with hydrogen. The difference is the hydrogeninduced additive stress, which can help the external stress to enhance the plastic deformation. The hydrogeninduced…
