Tertiary treatment of municipal wastewater is necessary to reduce its scaling potential for using as makeup water of circulating cooling systems. In this study the corrosivity and the factors affecting corrosion of municipal wastewater tertiary-treated by nanofiltration membrane process were assessed by weight-loss me…
Nanocrystalline magnets (SmCo5)94(Cr3C2)6 were prepared using melt-spinning and their magnetic behaviors were investigated by studying their structures and magnetic properties. The alloys prepared using rapid solidification consisted of SmCo5 matrix phase, MgCu2-type SmCo2 secondary phase, and small traces of Sm2Co7 p…
The traditional method of preparing 0.5 wt.% nano Pd/C catalysts used for pure terephthalic acid(PTA) refining is the precipitate-reduction method, and this paper proposed the sol-gel method, in which the palladium colloid was firstly prepared, and followed by the load process onto the activated carbon. The activity a…
High pure zinc with trace titanium of various contents was prepared by the method of master alloy preparation, and electrochemical characteristic difference in seawater was discussed. The result reveals that there is a minimum of self corrosion current density at 0.04% titanium content in high pure zinc in seawater of…
Rhombohedral bismuth ferrite (BiFeO3) powders were hydrothermally synthesized by using C6H8BiNO7 and Fe (NO3)·5H2O as precursors, KOH as a mineralizer and poly sodium-p-styrenesulfonate (PSS) as an additive. The phase formation and morphology of the as-prepared powders were characterized by X-ray diffraction,raman spe…
Tetragonal (123) phases of compositions Ca 0.7 Na 0.3 Ba 2 Cu 2 WO 8 , CaBa 1.7 Na 0.3 Cu 2 WO 8 , and CaBa 1.7 K 0.3 Cu 2 WO 8 , where tungsten occurs in Cu(1) positions and Cu 3+ is in Cu(2) positions, were prepared from CaWO 4 , BaCuO 2 , and sodium and potassium nitrates at 1073 K in an oxygen flow. These phases c…
Aluminum ester grafted polypropylene copolymer (PP-g-DL411) compatibilizer and PP-g-DL411/GF/PP composites are prepared by melting cross blend. FTIR results show that DL411 grafts on PP molecular chains and leads to a new PP-g-DL411 copolymer. SEM reveals that PP-g-DL411 can effectively improve the interface compatibi…
The hysteretic behavioral features of magnetization and resistance upon remagnetization in quasistatic (up to 9 T) and pulse (up to 14 T) magnetic fields have been investigated. The relaxation processes of magnetization and resistance after the effect of a 9 T magnetic field have also been studied. A mechanism of the…
Metallic oxide ZnO short-nanorod of 33-83 nm in diameters and length up to 0.3um.with biological compatibility are environmentally fabricated by organic solvent-assisted annealing pro- cess. The sample was characterized by X-ray diffraction, field-emission scanning electron microscopy (FE-SEM), high-resolution transmi…
Although the research on the safety of the nanomaterials has made some progress, there are still some problems, such as: lacking the knowledge of the entire life cycle of nanomaterials----the production, the application and the transformation; more research on the safety of the nanomaterials which enter the body throu…
The coefficient of extinction of electromagnetic waves of the microwave range due to their scattering from clusters suspended in an amorphous medium and responsible for turbidity is calculated. Turbidity resembles the case when butter clusters transform water into milk. In the case under investigation, the clusters ar…
Frozen food is popular with more and more customers nowadays, it's consumption is growing rapidly.The packaging of the frozen food usually uses paperboard. Frozen food may suffer temperature fluctuations in the process of storage, transportation and sales, which cause the paperboard sop up , the strength come down and…

The effect of severe plastic deformation at ambient temperature on microstructures and mechanical properties of aluminum alloy 2519 was investigated by means of tensile test, micro-hardness test, optical microscopy and scanning electron microscopy. The results showed that tensile strength of as-queched 2519 alloy was…
The principle and technical characteristics of flue gas simultaneous removal of SO2 and NOx technology are expounded. The application and research progresses about this field are introduced. Besides that, the major research directions of flue gas ammonia combined desulphurization and denitration technology are prospec…
Tube hydroforming is a technology that utilizes hydraulic pressure to form a tube into desired shapes inside die cavities. Due to its advantages, such as weight reduction, increased strength, improved quality, and reduced tooling cost, single-layered tube hydroforming is widely used in industry. However in some specia…
In recent years, electrospinning has received much attention to prepare porous tubular scaffold due to electrospun nanofibers mat, which can mimic the structure characteristics of the extracellular matrix (ECM). In the present paper, silk fibroin (SF) tubular scaffolds with small-diameter were prepared by electrospinn…
The development of highly sensitive, selective, reliable, low power and compact sensing devices to detect gas is of major importance for terrestrial and space applications. The gas response to different gases and chemicals is related to a great extent to the surface state and morphology of the materials. Zinc oxide (Z…
Self-assembled face-centered cubic FePt nanoparticles were embedded into the oxide capping layer using the atomic layer deposition technology. The eect of the oxide-matrix layer on the structure, mono-dispersibility, and magnetic properties of the FePt/oxide composite thin lms was investigated. Experimental results su…
Subwavelength nanohole arrays have been thoroughly studied for years. However, investigations on nanoholes with defects are seldom reported. Here, we study the optical properties of nanohole arrays with different defects which are fabricated by focused ion beam lithography. Finite difference time domain simulations ar…
