Electrospinning is a cheap and stable technique that allows the fabrication of continuous and uniform fibers, either organic or inorganic, with diameters ranging from tens of nanometers to several micrometers for mass production [5−7]. Moreover, highly ordered aligned nanowire array (NWA) can also be easily achieved on various substrates based on modified electrospinning, which is greatly beneficial to the following applications of NWs in various fields shown in Fig. 1. In this review, we provide a concise retrospection on the assembling methods and primarily highlight the electrospinning method and corresponding applications of NWA including electrodes, field effect transistors (FET), piezoelectric sensor, gas sensor, and photodetectors. We also give comments and prospection in the ABSTRACT Alignment of NWs (NWs) is the core issue for integrating NWs into nanodevices in future. This review made a concise retrospect on reported assembling methods and mainly emphasized on the electrospinning method and its developments, as well as the following applications of the aligned nanowire array (NWA) in electronics and optoelectronics. First, we classified reported assembling methods into three categories: "grow then place", "place then grow" and "grow and place" (electrospinning method). Then, we focused on the electrospinning method and its modified method including field assisted method, rotating collector assisted method and near-field assisted methods, as well as their merits and defects, respectively. Next, we illustrated the applications of the NWs arrays fabricated by electrospinning in field effect transistors (FET), gas sensors, piezoelectric sensors and photodetectors. Finally, we made a short conclusion and prospection on electrospinning method. As an easy and cheap nanowire fabrication and alignment method, electrospinning has a bright future in one-dimensional materials based electronics and optoelectronics.

“…As the world is shifting from electrical equipment to electronic devices due to the energy crisis, it is leading to a reduction in electrical power consumption, resulting in micro and nano powered electronic circuits [5][6][7]. Numerous researchers have focused on the usage of PEHs as self-powered sources over the storage of electric voltage in batteries because of the voltage drop [8,9].…”

A Review on Mechanisms for Piezoelectric-Based Energy Harvesters

From last few decades, piezoelectric materials have played a vital role as a mechanism of energy harvesting, as they have the tendency to absorb energy from the environment and transform it to electrical energy that can be used to drive electronic devices directly or indirectly. The power of electronic circuits has been cut down to nano or micro watts, which leads towards the development of self-designed piezoelectric transducers that can overcome power generation problems and can be self-powered. Moreover, piezoelectric energy harvesters (PEHs) can reduce the need for batteries, resulting in optimization of the weight of structures. These mechanisms are of great interest for many researchers, as piezoelectric transducers are capable of generating electric voltage in response to thermal, electrical, mechanical and electromagnetic input. In this review paper, Fluid Structure Interaction-based, human-based, and vibration-based energy harvesting mechanisms were studied. Moreover, qualitative and quantitative analysis of existing PEH mechanisms has been carried out.

“…However, the drawback of these methods is that they only transfer the non-biodegradable matter into sludge, giving rise to a new type of pollution, which needs further treatment [10][11]. Among various oxide semiconductor photocatalysts, TiO 2 photocatalyst is found to be a more efficient catalyst for photocatalytic degradation of pollutants due to faster electron transfer to molecular oxygen [12]. Apart from that, TiO 2 is the most suitable catalyst for widespread environmental application because of its biological and chemical inertness, strong oxidizing power, non-toxicity and longterm stability against photo and chemical corrosion [13][14].…”

Abstract. Titanium dioxide (TiO2) nanotubes have successfully been synthesized by using one step approach of hydrothermal method. Commercial TiO 2 (anatase) powder was used as precursor to synthesize the TiO2 nanotubes. The TiO 2 nanotubes were synthesized at 120 o C/20 hrs in an alkaline solution of NaOH. The photocatalytic study of the as-synthesized samples was conducted by analyzing the degradation of Rhodamine B (Rh B) dye under UV light irradiation. Rh B is a toxic dye which is commonly used in textile industry. It is the one of the most common pollutants in the effluents and highly soluble in water. A comparison study was carried out in order to investigate the photocatalytic activity between the synthesized TiO 2 nanotubes and the commercial TiO2 nanoparticles. Results show that the TiO 2 nanotubes exhibits better photocatalytic activity in the degradation of Rh B as compared to the TiO2 nanoparticles.
