Nanofluidic devices have many potential applications in biomedical field. One of the technical barriers of nanofluidics is to drive nanofluids in nanochannels with super-high hydraulic resistance (MPa scale) and super-small volume (fL scale). Electric field driving method (eg. electroosmotic flow) is commonly used in nanofluidics, since the conventional pumps applied in microfluidics are limited by their low pressure and low control precision. However, the electric field driving method is not suitable for all kinds of the nanofluids, which could affect the biochemical reactions, and lead to electrolytic reactions. We have developed a new type of high pressure nanofluidic micro-pump based on electrolysis. The pump system consists of electrolytic chamber, pressure sensor, control circuit, electrolytic electrodes and sample chamber that connects to nanofluidic chip. In our nanofluidic micro-pump system, high pressure gas generated from the electrolytic chamber pushes the liquid sample into the nanochannel, and the driving pressure to the fluidic sample can stably reach to 20MPa. Our high pressure micro-pump is suitable for both microfluidic and nanofluidic applications due to its very high output pressure, high control precision, fast response and wide output range.

A novel high natural frequency microgripper with symmetric compliance structure is reported in this paper, which is actuated by a piezoelectric actuator (PZT). Two lever mechanisms are utilized to amplify the output displacement of the PZT to achieve a large jaw desired output displacement. The symmetric lever mechanism and the jaws are designed separately and then the microgripper is constructed by assembling the two parts together. So different kinds of objects can be manipulated through designing different jaws, which broaden the application of the microgripper. The analytical model has been established based on pseudo-rigid-body (PRB) modeling method and matrix-based compliance modeling (MCM) method. According to the established model, the performance of the microgripper including amplification ratio, input stiffness and natural frequency are analyzed. Finite element analysis (FEA) is carried out to investigate the performance and validate the theoretical models for further optimum design of the microgripper.

Micro-EDM is a non-contact machining method. There is a certain discharge gap between the tool electrode and the workpiece during machining. The size and consistency of the discharge gap have great influences on the machining precision of the micro hole machining, which seriously affects the machining precision of the titanium alloy micropore. In this paper, through the different peak current, peak voltage, pulse width, pulse interval and other parameters of the blind hole processing test, the effects of various factors on the discharge gap. Thus, the size of the tool electrode can be adjusted to compensate for the effect of the discharge gap on the dimensional accuracy.

Cobalt metal-organic framework (Co-MOF) has been synthesized using a hydrothermal method and applied as Co-MOF modified electrode in supercapacitors. Multiple techniques like scanning electron microscope, transmission electron microscope, X-ray diffraction and Brunauer-Emmett-Teller analyzer were employed to investigate Co-MOF structure and textual characteristics. Co-MOF has high specific surface area due to the hollow structure with mesopore voids. The electrochemical behavior of the as-prepared Co-MOF was analyzed by cyclic voltammetry, galvanostatic charge-discharge tests and electrochemical impedance spectroscopy. The results exhibit good capacitive behavior of Co-MOF because the high specific surface area and numerus mesopore voids promote the transportation of electrolyte ions, which shows good capacitive stability as a supercapacitor electrode.

Recent progress in the study of new functional materials, such as Ti(NiCu) intermetallic with shape memory effect (SME), opens up exciting possibilities for the design reconfigurable micro- and nano-structures and for operating mechanical nanotools controlled by external fields or heat. This report gives an overview of physical effects, in particular, solid state phase transitions and accompanying phenomena in alloys and composites exhibiting SME. The limitations pertaining to the minimum size of the nanomechanical devices exhibiting shape memory effect that arise due to the solid state phase transitions are now under discussion and have not been completely understood yet. The modern nanotechnologies allow designing of the mechanical micro- and nanotools, such as nanotweezers, nanopinchers etc., with an active layer thickness of about several tenths of nm, and whose overall size is below 1 μm. The nanotools with SME can be controlled by heating as well as by magnetic field activation in ferromagnetic alloys exhibiting SME, such as Ni2MnGa. 3D nanomanipulation is demonstrated by composite nanotweezers with SME in different nanoobjects, such as CNTs, nanowires, nanowhiskers, bionanoobjects, DNA, etc. In these devices, the surface interactions and Casimir and van der Waals forces affect the process of nanomanipulation. The prospects of nanorobotics and manufacturing on nanoscale adapting the principle of mechanical bottom-up nanoassembly are discussed. In addition, nanoscale measurements can take advantage of 3D mechanical nanomanipulation, including transportation of analytes to nanosensors, elasticity measurements by nanotools with calibrated force, etc.

In this paper, we present a graphene-based metamaterial absorber, which is comprised of three layers with a meta-dielectric-graphene structure. Numerical simulations demonstrate that two high absorptivity of 99.9% at 6.62THz and 98.9 % at 9.36THz are produced, respectively in terahertz band, and the resonance amplitude and frequency of the absorber can be controlled flexibly by changing the Fermi level of graphene, and when the relaxation time of graphene changes, the absorption intensity of the metamaterial absorber can be individually controlled. In addition, we show the thickness of the intermediate dielectric layer of the proposed absorber affects the absorptivity, which is conducive to determine the initial processing parameters of the absorber. The study demonstrates that the graphene-based metamaterial absorber proposed in this paper has a simple structure and is easy to fabricate, moreover, it is very convenient to achieve the flexible tuning of metamaterial absorbers by biased voltages or chemical dopings, and it provides an important guide for designing dual-band absorbers with high absorptivity.

The shape of transition structure has significantly influence on the mechanics properties of dragonfly wing structure. In this paper, four bionic models with three different transition structures were designed by comparing and analyzing samples of dragonfly wings. The simulation results of the four bionic models by ANSYS were analyzed and compared, which provided a design basis for the bionic thin solid membrane.

Inorganic particles have been widely used as fillers for stiffness enhancement of polymers. In this paper, the filler particle size is fixed, and relationship between filler fraction and elastic modulus has been studied in Al(OH)3/polyethylene composites. By measuring the elastic moduli of composite samples with different filler content, the highest value of elastic modulus is found around 40% filler weight fraction. In distance-dependent elastic modulus analysis the peak elastic modulus of PE is obtained at a distance of 430 nm to filler center, which corresponds with body-centred cubic packing type. Our research may be helpful in improving mechanical property of polymer materials.

This study is devoted to the creation and characterization of nano-electronic devices fabricated from bundles of functionalized carbon nanotubes as well as multilayer graphene. The fabrication technique focuses on nanointegration utilizing a nano-tweezer created from memory metal. The devices envisioned include crossed junction as well as fine network structures that can be manipulated using nano-probes. As the carbon nanotubes have been functionalized with nanoscale magnetic molecules, such devices are interesting for novel spintronic applications. In addition, the fabrication of multi-layered graphene structures is demonstrated, these devices are particularly interesting for investigating the effect of local deformations which can be induced through the manipulation process.

In this paper, SiCp/2024Al composites was drilled by electrical discharge machining (EDM) to investigate the effect of different electrode cross-section shapes on material removal rate (MRR). The material removal mechanism (MRM) at different discharge energy were also analyzed by changing the electrical parameters. It is found that the MRR of EDM with tube electrode is 5 times greater than that of with cylinder electrode. Electro-erosion debris filled in the discharge gap makes the tool electrode retreat frequently, greatly reducing the MRR. The MRM includes thermal spalling, melting/vaporization and oxidation. The MRM varies with different discharge energy. Thermal spalling is the main MRM at low discharge energy, while melting/evaporation occupies a dominant position in MRM at high discharge energy. Either low or high discharge energy, oxidation always occurs.
