Influence of nanodispersed refractory compounds on structure and mechanical properties of heat-resistant alloys K403 and K4169 was investigated. Powders of chemical compounds TiN, TiCN, Y2O3 and their mixtures were used as the modifying agents. The results show that the modifying leads to general improvement of grain and carbide structure of heat-resistant alloys in casts. The grain average size in the cast decreased by 2-3 times, the carbide grains size decreased from 40-60 μm to 10-20 μm. This leads to significant improvement of the life at breaking load and LCF properties of the cast.

Calibration is of great significance in the development of automatic micromanipulation systems. This paper presents a novel vision based procedure for three dimensional (3D) calibration of micromanipulators. Two major issues in the proposed calibration approach - vision system calibration and manipulator kinematic calibration - are discussed in details in this paper. Verification and evaluation experiments are conducted using a 3D micromanipulator in a microrobotic fiber characterization platform. The results demonstrate that the proposed calibration approach is able to reduce the pose error below 5 micrometers.

Printing techniques develop rapidly especially in the areas of electronics and biotechnology in these decades. In this paper, first we describe the use of electrohydrodynamics for jet printing the lines with the sub-micrometer resolution. It also presents the complex pattern printed by electrohydrodynamics jet printing with the same resolution combined with the automatic control technology. In the second part, we research on the parameters which affect the width of the printed lines by a series of experiments. Such experiments focus on the effect of voltage and distance between the tip of the nozzle and the substrate, in addition, concentration of the printed solution and the inner diameter of the nozzle are also considered.

A new concept of Atomic Force Microscope (AFM) oscillating probes using electrostatic excitation and piezo-resistive detection is presented. The probe is characterized by electrical methods in a vacuum chamber and by mechanical methods in air. The frequency-mixing measurement technique is developed to reduce the parasitic signal level. These probes resonant in the 1MHz range and the quality factor is measured about 53,000 in vacuum and 3,000 in air. The ring probe is mounted onto a commercial AFM set-up and the surface topography of PMMA sample (2 μm square) is obtained. The force resolution deduced from the measurements is about 10 pN/Hz0.5.

Micro- and nanoscale structures on a material surface formed by femotosecond laser processing have greatly changed its optical characteristics. In this work, the coloring of Al surface has been realized with scanning focused femtosecond laser beam on the Al surface. We further apply femtosecond laser filamentation to form micro- and nano-structures on a spherical Al surface, resulting in a black appearance of the spherical Al. This work opens ways to fabricate strong light-trapping micro- and nano-structure on a non-planar surface without the complexity of a 4-axis sample control.

A decoupled piezo-driven compliant mechanism has been designed and manufactured to track 2-DOF trajectories. Although it features decoupled characteristics, the small cross axis coupling can result in poor tracking performance in 2-DOF trajectories. For such structures, the damping ratio is so small that the modal vibrations are likely to be excited, which greatly degrade its positioning accuracy. In this paper, an H∞ controller is designed to make the closed-loop system match a well-damped second order system. The H∞ controller effectively suppresses the modal vibrations and further reduces the cross axis coupling motions. Experimental results show that the mechanism's tracking performance in 2-DOF trajectories is significantly improved.

A molecular structural mechanics model, based on a link between molecular and solid mechanics, was built to evaluate mechanical properties of graphene nanoribbons (GNRs). This model can describe the true state of GNRs more realistically comparing to other simulation methods because of considering the structure and properties of the carbon-carbon bonds. GNRs with different edge types, such as armchair and zigzag types, were simulated under a uniaxial load by using the proposed model. The Young's moduli of GNRs were obtained. Then the influence of edge type and size of GNRs on Young's modulus was also investigated. The results show that GNRs have a similar Young's modulus to carbon nanotubes, which is in good agreement with the previous studies, indicating that the proposed molecular structural mechanics model can be used to predicate the mechanical properties of GNRs.

We electrothermally determined the internal electrical resistivity of a single carbon nanocoil (CNC) which was assembled on the AFM tip. A heat-transfer modeling which considered the Joule's heat was employed to extract the electrical resistivity. The current and resistance of the loop circuits were applied in the calculation in which the thermal measurement was not required. During the electrical measurement, the overall resistance of the heating loop depended on the current variation and decreased abruptly at the beginning of the measurement. It was suggested that the contact resistances between the CNC and metal electrodes were eliminated due to the shortened difference of the work functions between the two materials. The developed electrothermal model agreed well with the experiment at steady state and gave the CNC resistivity of 1.64*10-4~8.81*10-4 Ω-m. This result confirmed the amorphous phase of the synthesized CNC.
