aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

The street garment vendors are playing a significant role in the fields of the economic development through protecting resources (garment products) from such a position where they are treated as wastes; very much less valued products and creating the opportunity for self-employment. This study aimed at showing the economic contribution and the impact of the street vendors to the local community...

Introduction: Lichen dominated cryptoendolithic communities from the Dry Valleys of Antarctica have been the subject of much research over recent years owing to their potential as analogues of Martian lifeforms. This is primarily owing to the stress tolerant nature of the microorganisms, remarkable adaptive achievements and the similarities between the Antarctic Dry Valley ecosystems and condit...

This study introduced a method based on magnetic field assisted finishing mechanism for micromachining the inner surfaces of Aluminum tubes. In this approach, using the alternating magnetic field of an AC electromotor, abrasive particles were formed as Magnetic Rods (Magnetic Clusters) and surface micromachining was carried out by the dynamic particular pattern made by an alternating magnetic f...

Alteration of iron sulfides on the lunar surface by space weathering is poorly understood. We examined features in mature soil grains using scanning electron microscopy (SEM) and transmission (TEM). SEM observations reveal that have vesicular textures whiskers their surfaces. Iron observed TEM are troilite NC-pyrrhotite. The space-weathered rim characterized crystallographic misorientations dis...

iron oxide minerals in soils provide valuable insights into pedogenic processes. a wealth of such information has been obtained by rock magnetic investigations on temperate soils but similar studies on tropical soils are rare. here, we report rock magnetic data on pristine soil profiles and surficial soils from five catchments in the tropical southern india and throw light on the pedogenic pro...
