AbstractRecent developments show encouraging results for the use of DNA as a construction material for nanometer‐sized objects. Today, however, DNA‐based molecular nanoarchitectures are constructed with mainly unmodified or at best end‐modified oligonucleotides, thus shifting the development of functionalized DNA structures into the limelight.

A base metal alloy for ceramo-metal restorations
The Journal of Prosthetic Dentistry, 1980Research of the existing scientific literature and examination of multiple porcelain/metal samples indicate that Ni/Cr is not only compatible with veneering porcelain but, indeed, can probably be the basis for superior ceramo-metal restorations.

Misch metal based metallic glasses
Journal of Alloys and Compounds, 2008Abstract In this paper, a glass-forming range of metallic glasses based on Ce-rich misch metal (Mm) was pinpointed in Mm-Al-Co composition map by melt spinning. The thermal analysis indicated that the wide supercooled liquid region (above 60 K) can be found out in a large composition range in Mm-Al-Co system.

The base metals copper, lead, nickel and zinc provide a range of crucial functions in modern technology, products and infrastructure. While mineral resources are effectively non-renewable and arguably finite, ongoing growth in production rates raises important questions about the long-term sustainability of base metals mining.

Metallizations of InP based on transition metals
Physica Scripta, 1994Single element Ni and Cr metallizations to low doped n- and InP have been investigated to clarify how they affect electrical performance of advanced multilayer metallizations for ohmic contact and Schottky diode applications. It was found that the Ni and Cr contacts to n-InP show unstable ohmic behaviour at all annealing temperatures (300-500 °C), and ...

Metallic plastics based on misch metals
Journal of Non-Crystalline Solids, 2006We report a family of metallic plastics (MPs) based on misch metals with extremely low glass transition temperature Tg, similar to that of typical polymers such as polyvinyl chloride. In near boiling water, these MPs show superplasticity and can be shaped and imprinted with complex micro- or nano-patterns.

Metal‐Based Diversity for Crystalline Metal‐Fullerene Frameworks
Chemistry – A European Journal, 2017AbstractFour different three‐dimensional metal–fullerene frameworks were synthesized through polymerization of two C60‐derived dodecaacids with varying alkyl spacers in the presence of Ca2+, Cu2+ or Cd2+ ions. Structural analysis of the frameworks was performed by single‐crystal X‐ray diffraction and porosity of the materials was investigated by ...

Metal–salophen-based receptors for anions
Chemical Society Reviews, 2010In this critical review the use of metal-salophen complexes as anion receptors is discussed with an emphasis on the supramolecular control of selectivity derived by the presence of additional interaction sites on the ligand skeleton. Some examples of application in sensing are also reported (112 references).

Organic or metal bases for dentures
The Journal of Prosthetic Dentistry, 1967Abstract Research findings indicate that all denture resins exhibit dimensional changes during processing. Such warpage is likely to be damaging to the tissues that support removable dentures. Therefore, the scientific method requires the use of discrimination when organic (acrylic) resin complete denture bases are used.
