It is has long been known that the grain size of a material has a substantial effect on its mechanical strength, through the well-established Hall-Petch relationship. In the past decade or so, there has been a resurgence of interest in this topic resulting from the ability to create metals with grain sizes in the deep sub-micron to nano-crystalline scale via a variety of processing techniques. In these materials, it has been conjectured that it may no longer be possible to deform individual grains via simple unit dislocation processes, and other mechanisms may be required to achieve plastic flow.

Nano-size objects are smaller than the wavelength of light and because of this they cannot be viewed with a light microscope.  Special tools are needed to see nanoscale objects, one of which is the scanning electron microscope. This activity will have students explore the types of images that can obtained using an SEM.

This tutorial presents a broad overview of the basic physical principles of techniques used in scanning electron microscopy (SEM), as well as their application to understanding processing/structure/property relationships in nanostructured materials. Special emphasis is placed on the capabilities (existing and planned) in the microscopy labs of the Birck Nanotechnology Center at Purdue University.

“Nanomaterials,” is an interdisciplinary introduction to processing, structure, and properties of materials at the nanometer length scale. The course will cover recent breakthroughs and assess the impact of this burgeoning field. Specific nanofabrication topics include epitaxy, beam lithographies, self- assembly, biocatalytic synthesis, atom optics, and scanning probe lithography. The unique size- dependent properties (mechanical, thermal, chemical, optical, electronic, and magnetic) that result from nanoscale structure will be explored in the context of technological applications including computation, magnetic storage, sensors, and actuators.

5 Amazing Festivals in Goa

A grant welcome to this party is announced every year. People love this festival as it’s very exciting. It is World’s Biggest “WINE FESTIVAL” held in India. Many love being thereafter or before experiencing sea water sports activities. Though it started in 2005, it is glamorously celebrated with wines, haute cuisine, and restaurants, hoteliers, wineries, and lifestyle brands that are all under one roof. The Grape Stomping is yet another exciting and is celebrated from traditional days, a source of many delights and fun for the visitors. scuba diving in goa

Top Goa Beaches Spots

Goa beaches are principally categorized into two areas north and south Goa beaches, keeping in mind the geographical locality. North Goa beaches include beaches such as Candolim beach, Sinquerim beach, Baga beach, Bambolim beach, Arambol beach, Vagator beach etc where as South Goa beaches include beaches such as Agonda beach, Benaulim beach, Palolem beach, Movor and Cavelossim beach. It is believed that North Goa beaches are hot and happening with a cosmopolitan crowd thronging the beaches whereas South Goa beaches are peaceful and silent and are considered to be a perfect place for a great vacation.
