ELECTROLESS DEPOSITION OF SUPERCONDUCTING MAGNESIUM DIBORIDETHIN FILMS ON VARIOUS SUBSTRATES

can be varied from perfectly isotropic to exactly straight. Also positive or negative tapering is po~s ib le .~ Various ways of fabricating channels in silicon are The basic approach for disyussed. Some new channels are presented: the constructing channels in GPSIC's and the LPCVD covered channels. Also some silicon is almost always attention is paid to the problem of making connections as depi...

Bioprospecting, defined as the systematic search for valuable, molecules, genes and organisms in nature, has the potential to offer island countries a means to use biodiversity without disrupting nature; to add value to their natural resources; to ensure that such resources are protected and used in a sustainable manner; and to build the necessary skills to apply biotechnology in improving qual...

This study focuses on the manufacture of carbon nanotubes using the arc discharge method. Several independent variables were changed, such as the current (80 and 100 A), an atmosphere of open air or argon and the catalyst (no catalyst, Fe or a mixture of Fe/Co,Ni). Only one set of parameters yielded MWNTs, involving Fe as the catalyst and an open air atmosphere. I. INTRODUCTION There has been i...

Do we need an international regime on access to genetic resources and benefit sharing (ABS) ? The Seventh Conference of the Parties (COP) of the Convention on Biological Diversity (CBD, 2003) to be held in February 2004 will probably give a political answer to this question. However, we would hope there is time for further legal, technical and economic analysis of this proposal before a definit...

Outstanding among the global environmental issues that have emerged since the 1980s is the issue of the rapid loss of biodiversity. This is an issue that is urgent from the ecological standpoint and strategic from the economic, political and social standpoints. With the Convention on Biological Diversity (CBD, 1992) a new global framework was introduced, together with a new international code o...
