Nowadays the treatment way of circulating cooling water is mainly confined in the scale removal direction and effect is limited, but in scale inhibition direction few reports. To solve this problem, the study proposed a new technology of high-frequency electric field-colloid-electric adsorption. Simulation circulating water was treated by the self-made electrolytic system in high frequency DC electric field, obtained the optimum conditions by adjusting different electrochemical parameters, and analysed the mechanism of the process. The result suggests that this process has excellent scale inhibition, it reflected the good descaling effect by soften and peel the aging scale, it also can effectively change the crystal morphology, it is convenient, efficient and environment friendly.

Time Projection

We present a new technology for the shaping of the electric field in Time Projection Chambers (TPCs) using a carbon-loaded polyimide foil. This technology allows for the minimisation of passive material near the active volume of the TPC and, thus, is capable to reduce background events originating from radioactive decays or scattering on the material itself. Furthermore, the high and continuous electric resistivity of the foil limits the power dissipation per unit area and minimizes the risks of damages in the case of an electric field breakdown. Replacing the conventional field cage with a resistive plastic film structure called “shell” decreases the number of components within the TPC and, therefore, reduces the potential points of failure when operating the detector. A prototype liquid argon (LAr) TPC with such a resistive shell and with a cathode made of the same material was successfully tested for long-term operation with electric field values up to 1.6 k V cm − 1 . The experiment shows that it is feasible to successfully produce and shape the electric field in liquefied noble-gas detectors with this new technology.

Electric field enhanced molecular delivery for cancer research and treatment is a new technology that has demonstrated its effectiveness in clinical trials using bleomycin or cisplatin (Heller, R., Gilbert, R., Jaroszeski, M. J. Clinical applications of electrocemotherapy. Advanced Drug Delivery Reviews 35, 119–129 (1999)), as chemotherapeutic agents. The technology is being investigated in research applications for applicability as a method to enhance gene expression in a target tumor. Success is predicated on an appropriate effective electric field mediated delivery protocol that triggers significant appropriate gene expression duration and levels. An electric field mediated delivery protocol includes a set of conditions associated with the electric field, the electroporation signature, as well as parameters associated with the plasmid and the electric field applicator. Manipulation of the electrical parameters within the electroporation signature generates different gene expression levels in liver hepatocellular carcinomas. Statistically significant gene expression levels were obtained that differed by an order of magnitude when two different electric field strength and duration conditions were employed.

Enhanced Yield

A new technology, compression-assisted aggregation, is developed to enhance the strength of electrorheological (ER) fluids. The yield shear stress of ER fluids depends on the fluid microstructure. The unassisted electric-field induced ER structure mainly consists of single chains, whose weak points are at their ends. This new technology produces a structure consisting of robust thick columns with strong ends. As the weak points of the original ER structure are greatly enforced, the new structure makes ER fluids super-strong: At a moderate electric field and moderate pressure the yield shear stress of ER fluids at 35% volume fraction exceeds 100 kPa, well above any requirement for major industrial applications.

A new technology of the electric-field manipulation by dielectric particles in dielectric liquids and drops has been developed in the last decades. To simulate electromechanics of microparticles in a weaklyconducting dielectric drop the Taylor's leaky-dielectric model is extended. To achieve this electric-potential distribution inside and outside a weakly-conducting dielectric sphere embedded in a weakly-conducting dielectric in an electric field is determined taking into account the interfacial current. The conventional definition of the total, bulk plus surface, conductance of the sphere is detailed allowing for its dependence on the angular distribution of the external electric field. Technology of microparticles moving over the interface of the drop is based on the application of electrohydrodynamic (EHD) drag and dielectrophoretic (DEP) forces. The surface conductivities of the drop and individual microparticles can have a significant influence on the surface charge and thereby on the DEP and EHD drag forces. Thus, we show that recent explanation of manipulation by microparticles trapped at the interface of a silicone-oil drop immersed in castor oil is misleading. Taking into account the surface conductivity of the microparticles, we find that EHD drag and DEP forces are of the same direction but not opposite at zero or low frequencies as stated previously. Due to the reversal of the DEP force with the field frequency the motion of microparticles turns back. Surface conductivity of the drop can also explain experiments in which the prolate deformation persists after liquids of the drop and ambient medium are interchanged.

A new technology of initiative protection for lightning stroke based on electric field cancellation theory is presented in this paper. The real time lightning detection system and the active protection equipment are adopted. By using this new method, the protection technology of direct lightning stroke can be changed from little current triggering to weakening the electric field near the weapon system, and the down leader of charged thundercloud can be repulsed by the artificial opposed field. So the lightning discharge condition in this protection region can be destructed, and the lightning hazard to the protected equipment is eliminated radically. It effectively reduces the electromagnetic radiation, ground potential reaction and step voltage caused by the high current along conducting wire in the conventional lightning rod protection technology.

Most microelectronics devices and circuits operate faster, consume less power, execute more functions and cost less per circuit function when the feature-sizes internal to the devices and circuits are made smaller. This is part of the stimulus for the Very High-Speed Integrated Circuits (VHSIC) program. There is also a need for smaller, more sensitive sensors in a wide range of disciplines that includes electrochemistry, neurophysiology and ultra-high pressure solid state research. There is often fundamental new science (and sometimes new technology) to be revealed (and used) when a basic parameter such as size is extended to new dimensions, as is evident at the two extremes of smallness and largeness, high energy particle physics and cosmology, respectively. However, there is also a very important intermediate domain of size that spans from the diameter of a small cluster of atoms up to near one micrometer which may also have just as profound effects on society as “big” physics.
