Authors: Zhao Dong Jiao , Chen Yan Hong , Tu Chen Di , Xuan Yao Fang , Xi Feng Na
Published: January 2012

A general methodology to prepare reagentless biosensor was developed based on self-assembly and electrodeposition. Redox active inorganic multilayers consisting of copper hexacyanoferrate (CuHCF) multilayers were formed by successive self-assembly. A simple and controllable electrodeposition approach was established for one-step fabrication of chitosan-enzyme layer on CuHCF modified electrode. Horseradish peroxidase was selected as the model enzyme. With CuHCF as the electroactive mediator, the developed reagentless biosensor exhibited a fast amperometric response for the determination of hydrogen peroxide (H2O2). The linear response ranged from 1.4 × 10-5 to 2.0 × 10-4 M with a detection limit of 1.2 × 10-6 M. The biosensor exhibited high reproducibility and long-time storage stability. The proposed methodology could serve as a versatile platform for fabrication of electrochemical biosensors.

Authors: Yu San Chuan , Chen Zhi Wen , Liu Mei Hong , Zhao Jing Wei
Published: January 2012

In view of the water shortage, the increasingly severe regulations as well as the release thresholds, it is becoming increasingly necessary to reuse the textile effluents. This work concerned the treatment of textile plant effluent after conventional biological processing by membrane technology for water reuse. Desal5 DK nanofiltration (NF) membrane and BW30 reverse osmosis (RO) membrane were investigated in this study in terms of COD and color removal, salinity reduction as well as permeate flux through cross-flow permeation tests. The results showed that the Desal5 DK nanofiltration membrane exhibited higher stabilized water permeability and flux decline than the reverse osmosis membrane because of its higher porosity and tendency towards fouling. The BW30 reverse osmosis membrane reduced salinity to a great extent than the Desal5 DK nanofiltration membrane. While the nanofiltration membrane exhibited better COD removal efficiency compared to the RO membrane, possibly due to its sieving removal mechanism. The treated water with good enough quality could be recycled back into the process, thereby offering economical benefits by reducing the water consumption and wastewater treatment cost.

Authors: Nashed B. S. , Rice J.M. , Kim Yong K.
Published: January 2012

The bending toughness, strength retention, resistance to damage and bending stiffness of glass fiber mat, laminar composites under high strain rate impact loading conditions was studied. One of the main disadvantages of laminar composite materials is their poor interlaminar shear strength. Recent work has demonstrated a method of Z-direction reinforcement of these composites using electrostatic flocking techniques improve delamination resistance and fracture toughness without degrading the composites tensile strength or other in-plane properties when loaded quasi-statically. The Z-direction reinforcement is accomplished by electrostatically flocking short fibers perpendicular to and between the composite ply layers. In this study, composite samples were prepared using the flocking method in two fabrication modes by the; so-called Z-Axis wet and Z-Axis dry procedures. In this work, Z-direction reinforced composite panels (including a non reinforced control) that were previously projectile impact damaged were tested using established mechanical testing procedures. Damage areas were quantified and compared using image processing techniques. Three point bending tests were also conducted on these projectile impact damaged panels to determine and compare their bending toughness, strength retention and modulus. The results show that Z-Axis reinforcement by the flocking technique improves the overall mechanical strength and stiffness properties of glass fiber mat laminar composites. For example, Z-Axis reinforced projectile damaged and not damaged glass fiber mat composite laminates are found to have flexural strengths 9% to 15% higher and a flexural modulus (stiffness) 22% to 26% higher than comparable (not Z-Axis flock reinforced) glass fiber mat samples.

Wet-on-Wet Padding for Energy Conservation
Authors: Yang Yi Qi
Published: January 2012

We report a reconstitution method which could provide consistent shade depth and add-on in wet-on-wet pad/batch dyeing and finishing. Textile wet processing involves many steps of wetting and drying. Eliminating some of them by the wet-on-wet process could save energy. For a continuous process, due to the fast fabric movement, a wet fabric also could enhance chemical penetration for the improvement of properties and savings on auxiliary chemicals. One common problem associated with wet-on-wet process is that after padding several hundred yards of yarns/fabrics, chemical add-on is considerably decreased, resulting in the decreased shade depth or performance of the finished goods. This phenomenon is the result of water interchange in the chemical pad. Once the water interchange rate is obtained, quality of wet-on-wet finished materials could be controlled.

Authors: Ying Zheng
Published: January 2012

To estimate the pose of large aircraft component in pose adjustment quickly and accurately, a real-time estimation method based on Unscented Kalman filter (UKF) is proposed. Firstly, in the process of the aircraft component adjustment, a rough value of aircraft component’s pose is acquired by using forward kinematic model and the displacement of positioners on real time. Then, position of a measuring point fixed on aircraft component is obtained by a laser tracker. At last, UKF is employed to integrate the previous rough value and the measuring point position for evaluating the accurate pose of aircraft component. Numerical simulation results show that the presented method is achieved easily, calculated fast and high accurate.

Piezoelectric actuator is being widely used in precision positioning technology for its high resolution of displacement, high stiffness and fast frequency response. However, its hysteresis nonlinearity limited its control accuracy. The key way to eliminate this limitation is to describe the nonlinearity. Aiming at the inaccuracy of Preisach model, the characteristic of piezoelectric actuator was introduced, and its static hysteresis were studied by experiment. Then bilinear interpolation was introduced to calculate the Preisach model prediction which was not located in the experiment table, and a bilinear interpolation Preisach hybrid model was proposed. The experiment results revealed the proposed Preisach hybrid model to be an accurate one.

Published: January 2012

We describe a technique for the registration of three dimensional (3D) knee bone surface points from MR image data sets. This technique is grounded on a mathematical theory – Lipschitz optimization. Based on this theory, we propose a global search algorithm that simultaneously determines the transformation and point correspondences. Compared with the other three registration approaches (ICP, EM-ICP, and genetic algorithms), the new proposed method achieved the highest registration accuracy on animal data.

Published: January 2012

Based on the modified Maxwell-Wagner model, the molecular dynamics method is applied to simulate the three-dimensional structural changes of the electrorheological (ER) fluids in an electric field and a poiseuille flow field. And it is analyzed that the structure-force dynamic coupling is characterized significantly by capture effect. The simulation results show that: when the electric field is applied, a chain network will capture the upstream particles in the flow field causing the local electric field force changed. Eventually a body-centered tetrahedron (BCT) is formed, and the structure-force dynamic coupling characterizes significantly. For an ER fluids in a electric field, there exist a threshold of pressure gradient. Its significance of structure-force dynamic coupling is related to electric field intensity, pressure gradient or flow velocity.
