A bill to consolidate and amend the law relating to the scientific development and regulation of mines and minerals under the control of the Union. URL:[http://pib.nic.in/archieve/others/2011/sep/d2011093002.pdf].

The good and effective management of a new technology is fundamental for its success not only among the scientific and technical community, but especially for its entry and expansion in the market. There are many examples of new product or process technologies that, notwithstanding the...

A rapid and simple route to synthesize highly conductive graphene-based nanosheets for use as a flexible counter electrode in dye-sensitized solar cells is presented. The flexible counter electrode is free of transparent conductive oxide layer, i.e., TCO-free. A clean graphene with high quality...

Titanium and titanium alloys are widely used in many fields due to some of their characteristics such as light density, high strength, and excellent corrosion resistance. However, poor mechanical performances limit their practical applications. Laser gas nitriding is a promising method used to...

Currently, hydrogen may be stored as a compressed gas or as cryogenic liquid. Neither method appears to be practical for many applications in which hydrogen use would otherwise be attractive. For example, gaseous storage of stationary fuel is not feasible because of the large volume or weight of...

Surface oxidation of Ti was carried out using KrF excimer laser in the presence of O2. Different colors were obtained by varying the number of laser pulses at the fixed laser fluence. X-ray photoelectron spectroscopy shows that the outmost surface is composed of TiO2 and the inner layer consists...

In conjunction with TIMET at Waunarlwydd (Swansea, UK) a model has been developed that will optimise the scheduling of various blooms to their eight furnaces so as to minimise the time taken to roll these blooms into the finished mill products. This production scheduling model requires reliable...

Bi2Te3 has attracted attention due to its potential applications in the microfabrication of integrated thermoelectric devices. It is also interesting to study the metallization process of this compound. Metallic nanostructures were deposited by means of an electron gun evaporator in ultra high...

Unternehmenskonzentrationen im Weltbergbau warfen die Frage auf, ob die bisher problemlose Rohstoffversorgung der deutschen Wirtschaft über die Weltmärkte und ohne wesentliche eigene Rohstoffengagements im Ausland gefährdet werden könnte. In der Studie werden die Märkte von zehn...
