Inkjet printing, known as digital writing technique, can directly deposit functional materials to form pattern onto substrate. This paper provides an overview of inkjet printing technologies for flexible electronics. Firstly, we highlight materials challenges in implementing flexible devices into practical application, especially for inkjet printing process. Then the micro/nano-patterning technologies of inkjet printing are discussed, including conventional inkjet printing techniques and electrohydrodynamic printing techniques. Thirdly, the related equipments on inkjet printing are shown. Finally, challenges for its future development are also discussed. The main purpose of the work is to condense the basic knowledge and highlight the challenges associated with the burgeoning and exciting field of inkjet printing for flexible electronics.flexible electronics, nanomanufacturing, organic thin film transistor, micro/nano-patterning, inkjet printing, electrohydynamics, roll-to-roll Citation: Overview of flexible electronics technologyFlexible electronics, also known as printable/organic electronics, represent a technology for building electronic circuits by depositing electronic devices onto flexible substrates. Realization of flexible electronics with performance equal to conventional microelectronics built on brittle semiconductor wafers, but in high mobilities, optical transparency, light-weight, stretchable/bendable formats and easy to print rapidly over large areas would enable many new applications [1-4] not satisfied by a traditional rigid electronics. The applications vary from medicine and biology to energy technology and space science [1,2], such as flexible display [4,5], thin film solar cell [6,7], large area sensors and actuators [8,9], shown in Figure 1. These applications are based on thin film transistors (TFTs) which have strong materials and processes contents. Flexible electronics *Corresponding authors (have open boundaries that move with its development and applications and is a highly interdisciplinary field. As a result, there are considerable opportunities for innovation and basic scientific research into new types of electronic materials, processes and equipments.The flexibility, a critical issue in flexible electronics, is one of the most important differences from traditional microelectronics. Polymer organics and inorganic materials are the two kind of materials adopted in flexible electronics. The polymer organics are generally believed to be well suited for these applications and naturally compatible with polymeric substrates. However, the electrical properties is not ideal when devices are fabricated with polymer organics. This leads to interest in the possibility of inorganic based flexible electronics [10]. It is a challenge to design a bendable and stretchable electronics based on inorganic materials due to their small fracture strain. The most basic realization is thin films of the inorganics are adopted as semiconductors, conductors and/or insulators on substrates to mini-

“…Adding 1.4% of CaO (or 1.9% of Ca(OH) 2 ) to the residue however, improved these inconveniences but it would significantly change the leaching characteristics of the residue. Jaworek et al (2006) developed a multi-nozzle electrospray system as a source for charged droplet for cleaning a gas mixed with fine particles, like cigarette smoke that comprised particles in the submicron range. When the droplets were electrically charged, the removal efficiency of fine particles from the gas stream was shown to be significantly increased as compared to uncharged sprays.…”

Industrialization tends to be accompanied by growing population and increasing awareness on environmental problems, making the use of pollution control equipment imperative. However, the air pollution is a complex phenomenon, as the pollutants distributed in the air are molecularly more random than in other media (soil and water). The control of air pollution, therefore, often becomes a more energy intensive process, leading to increased CO 2 emissions. Further, air pollution comprises particulate and gaseous pollutions requiring different control philosophies. When the control of both particulate and gaseous pollutants is required in a single step, the selection of equipment is further complicated. This article outlines how such complications could be avoided by developing an understanding on the criteria of selecting air pollution control devices. The advantages and disadvantages of all generic control devices are critically appraised for the better understanding by both the designers and users. Emission trading, bubble policy, and the recommendations of the World Bank Guidelines for controlling particulates, SO 2 , and NO X pollution are highlighted. The recent research on the development of air pollution control devices are appraised critically. Finally, the criteria on selecting equipment for controlling particulate-laden-gaseous pollution in a single step are critically elucidated with few case studies.
