Researchers in Japan have successfully synthesized tungsten oxide nanotubes by a simple hydrothermal method. These nanotubes are composed of aggregates of crystallites and have a nanoporous structure with fine, nanometer-scale pores on their walls. This structure provides the nanotubes with a large specific surface area, enabling high photocatalytic activity.
The ninth edition of the Trends in Nanotechnology Conference (September 1-5, 2008) held in Oviedo, Spain, presented a broad range of current research in Nanoscience and Nanotechnology as well as related policies (European Commission, etc.) or other kind of initiatives (iNANO, CIC nanoGUNE, GDR-E, etc.).
Scientists in Spain have managed, by means of a numerical technique known as Transmission Line Matrix (TLM) Modelling method, to hide an object or make it invisible in a certain frequency, inside an electromagnetic simulator.
Researchers in Japan have revealed important information about why the threshold of gas pressure required for the structural transformation of flexible, three-dimensional molecular networks known as porous coordination polymers (PCPs) varies for different gases.
In a quest to push the limits of intensity to achieve extreme light-matter interactions in large molecules, a team of researchers from RIKEN?s Advanced Science Institute in Wako, the SPring-8 Center in Harima, and the University of Tokyo, has demonstrated the ionisation and consequently the dissociation of nitrogen molecules using a free-electron laser.
An unusual molecule once thought to be too strained to exist has been transformed into another contorted compound by RIKEN chemists, testing the limits of how far carbon-based molecules can be distorted by combining them with metal atoms.
Scientists have developed nanometer-sized 'cargo ships' that can sail throughout the body via the bloodstream without immediate detection from the body's immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected.
A team from Stevens Institute of Technology has been awarded a grant from the National Science Foundation for the project 'MRI: Acquisition of an Inductively Coupled Plasma Etching System for Nano/Micro Device Fabrication.'
It is the aim of this workshop to stimulate discussions and understanding of the general mechanisms and structural features behind self-assembled nanowire growth within the wide range of materials systems.
As we have written here before, the utter nonsense of claiming that nanotechnology products will be a 'trillion dollar market' has become a self-perpetuating claim that is eagerly adopted by politicians to push industrial policies, subsidies and investments.
