The present disclosure provides for thick fins on the surface of coils or tubes in a steam cracking furnace. The fins have a thickness at their base from ¼ to ¾ of the radius of the furnace tube. The fins have grooves or protuberances on not less than about 10% of a major surface. The fins help increase the radiant heat taken up by the tube from the walls and combustion gases in the furnace.

A metal gasket bellows seal includes a first ply comprised of a first material having a first yield strength. The metal gasket bellows seal also includes a second ply positioned adjacent to the first ply and comprised of a second material having a second yield strength that is less than the first yield strength.

The present invention relates to novel gold-platinum based bi-metallic nanocrystal suspensions that have nanocrystal surfaces that are substantially free from organic or other impurities or films associated with typical chemical reductants/stabilizers and/or raw materials used in nanoparticle formation processes. Specifically, the surfaces are “clean” relative to the surfaces of metal-based nanoparticles made using chemical reduction (and other) processes that require organic (or other) reductants and/or surfactants to grow (and/or suspend) metal nanoparticles from metal ions in a solution.

The invention includes novel electrochemical manufacturing apparatuses and techniques for making the bi-metallic nanocrystal suspensions. The techniques do not require the use or presence of chlorine ions/atoms and/or chlorides or chlorine-based materials for the manufacturing process/final suspension. The invention further includes pharmaceutical compositions thereof and the use of the bi-metallic nanocrystals or suspensions or colloids thereof for the treatment or prevention of diseases or conditions for which metal-based therapy is already known, including, for example, for cancerous diseases or conditions.
