Contouring measurement methods are important for high quality, high speed and productivity machining in order to achieve the high precision required. Among the most commonly used methods, no measuring techniques have been available with nanometer resolution except for the grating encoder measurement system.

Researchers in Israel demonstrated a new technique for creating polymer microlenses. While current processes employed for manufacturing large microlens arrays are not compatible with the need to place single microlenses in very precise, strategic locations (such as an intersection of two nanochannels, for example) the Israeli group's method is specifically designed to do so. They deposit small drops of monomer solution with a nanopipette, mounted as an AFM probe (nano fountain pen, or NFP), and subsequently polymerize them, to yield microlenses. Their technique could ultimately lead to nano-biochips with integrated polymer optics.

Carbon onions, which are made of concentric graphene spherical shells, are a potential solid lubricant similar to Tungstenite (WS2) nanoparticles having an onion-like structure. In addition, carbon onion nanoparticles are expected to have good prospects for other applications, such as the reinforcement of composite materials, magnetic storage media and wear-resistant materials.

Lithography is a critical enabling technology for manufacturing nanoscale devices and structures. Suppose nanolithography tools cost just a few thousand dollars a piece instead of a few million dollars. These cheap tools would wide open the fields of nanotechnology to practically every university and industry researcher interested in the field.

Researchers in Canada used the electroless deposition process for self-assembling Palladium nanostructures, such as wires, from nanoparticles on a rough stainless steel substrate. This discovery holds a lot of potential for various engineering applications because the deposition process and the preparation of the substrate are simple and inexpensive.

Building reliable interconnections between carbon nanotubes (CNTs) and external electrical and mechanical systems is an essential prerequisite to exploring the potential of CNTs in various domains. The formation of a stable and low-resistance ohmic contact between CNTs and electrodes contributes to speeding up the development of applications with CNTs in nanoelectronic devices with small size, fast speed and low power dissipation.
