“…<1 00) orientation and 1-5 Q cm resistivity. They were mechanically lapped on both sides and then textured in a solution of NaOH:IPA:H 2 0 at 85°C for Etching duration (s) For measurement of refractive index and thickness, the PS layers were created for etching durations of 20-480 s on Cz wafers chemically polished in a 1: 5: 1 solution of HF, HN0 3 and CH 3 COOH. The measurements of refractive index nps and thickness d of the PS layers were done at 630 nm using ellipsometry.…”

“…Formation of the PS layers and all the measurements on them have been carried out at 25°C. For measurements of refractive index and thickness the PS layers were formed on wafers chemically polished in a mixture of HF, HN0 3 and CH 3 COOH taken in ratio of 1:5: 1 by volume. The measurements of refractive index and thickness were done with an ellipsometer a Gaertner model L117 using a He-Ne laser (632.8 nm) as the light source.…”

“…The ALISTORE European Network of Excellence on Advanced Lithium Energy Storage Systems is aiming to increase the power output of rechargeable lithium batteries from the present 200 to 300 Wh/kg by using nanostructured electrode materials [32][33][34][35]. Electron production per electrode atom has been increased from 0.6 to 2 with nanostructured lithium cobalt oxide, formed in situ during the first charge cycle so no free nanoparticles are generated.…”

The potential positive and negative effects of nanotechnology on the environment are discussed. Advances in nanotechnology may be able to provide more sensitive detection systems for air and water quality monitoring, allowing the simultaneous measurement of multiple parameters and real time response capability. Metal oxide nanocatalysts are being developed for the prevention of pollution due to industrial emissions and the photocatalytic properties of titanium dioxide nanoparticles can be exploited to create self-cleaning surfaces that reduce existing pollution. However, while nanotechnology might provide solutions for certain environmental problems, relatively little is known at present about the environmental impact of nanoparticles, though in some cases chemical composition, size and shape have been shown to contribute to toxicological effects. Nanotechnology can assist resource saving through the use of lightweight, high strength materials based on carbon nanotubes and metal oxide frameworks as hydrogen storage materials. Other energy related applications include nanostructured electrode materials for improving the performance of lithium ion batteries and nanoporous silicon and titanium dioxide in advanced photovoltaic cells. It is important to develop an efficient strategy for the recycling and recovery of nanomaterials and methods are needed to assess whether the potential benefits of nanotechnology outweigh the risks. Life cycle analysis will be a useful tool for assessing the true environmental impacts. r

In this minreview, we summarize recent progress in the synthesis, properties and applications of a new type of one-dimensional nanostructures -single crystalline porous silicon nanowires. The growth of porous silicon nanowires starting from both p-and n-type Si wafers with a variety of dopant concentrations can be achieved through either one-step or two-step reactions. The mechanistic studies indicate the dopant concentration of Si wafers, oxidizer concentration, etching time and temperature can affect the morphology of the as-etched silicon nanowires. The porous silicon nanowires are both optically and electronically active and have been explored for potential applications in diverse areas including photocatalysis, lithium ion battery, gas sensor and drug delivery.
