Bonding chips using inkjet printers

Mar 14 11:43am Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
Today in electronics there are two main approaches to building circuits: the rigid one (silicon circuits) and the new, more appealing, flexible one based on paper and polymeric substrates that can be combined with 3-D printing. To date, chips are used to reach the reliable and high electrical performance needed for sophisticated specialized functions. However, for higher complexity systems such as computers or mobile phones, the chips must be bonded together. A team of Spanish researchers at the University of Barcelona have demonstrated a new bonding technique for such chips, called SMD or surface mounted devices, that uses an inkjet printer with ink that incorporates silver nanoparticles.

Two-dimensional MXene materials get their close-up

Mar 14 10:02am Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
Researchers have long sought electrically conductive materials for economical energy-storage devices. Two-dimensional (2-D) ceramics called MXenes are contenders. Unlike most 2-D ceramics, MXenes have inherently good conductivity because they are molecular sheets made from the carbides and nitrides of transition metals like titanium.

Nanoscale logic machines go beyond binary computing

Mar 14 9:30am Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
(Phys.org)—Scientists have built tiny logic machines out of single atoms that operate completely differently than conventional logic devices do. Instead of relying on the binary switching paradigm like that used by transistors in today's computers, the new nanoscale logic machines physically simulate the problems and take advantage of the inherent randomness that governs the behavior of physical systems at the nanoscale—randomness that is usually considered a drawback.

Guiding light with geometric phase

Mar 14 3:58am Nanowerk Nanotechnology News
Researchers demonstrate a novel mechansim for the realization of an optical waveguide. This opens the possibility to realize a waveguide without any modulation of the refractive index. The optical delay necessary for the beam confinement is not achieved by a local modulation of the speed of light, but through an exotic effect called 'geometric phase'. Geometric phase is a temporal delay associated with changes in the propagation of light polarization, the latter corresponding roughly to the oscillation direction of the electromagnetic field.

Researchers develop new method to program nanoparticle organization in polymer thin films

Mar 13 5:26pm Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
Controlling the organization of nanoparticles into patterns in ultrathin polymer films can be accomplished with entropy instead of chemistry, according to a discovery by Dr. Alamgir Karim, UA's Goodyear Tire and Rubber Company Professor of Polymer Engineering, and his student Dr. Ren Zhang. Polymer thin films are used in a variety of technological applications, for example paints, lubricants, and adhesives. Karim and Zhang have developed an original method—soft-confinement pattern-induced nanoparticle segregation (SCPINS)—to fabricate polymer nanocomposite thin films with well-controlled nanoparticle organization on a submicron scale. This new method uniquely controls the organization of any kind of nanoparticles into patterns in those films, which may be useful for applications involving sensors, nanowire circuitry or diffraction gratings, with proper subsequent processing steps lik...

The secrets of vibration-enhanced conductivity in graphene

Mar 8 10:30am Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
Graphene, the one-atom-thick material made of carbon atoms, still holds some unexplained qualities, which are important in connection with electronic applications where high-conductivity matters, ranging from smart materials that collectively respond to external stimuli in a coherent, tunable fashion, to light-induced, all-optical networks. Materials like graphene can exhibit a particular type of large-amplitude, stable vibrational modes that are localised, referred to as Discrete Breathers (DBs). The secret to enhancing conductivity by creating DBs lies in creating the external constraints to make atoms within the material oscillate perpendicular to the direction of the graphene sheet. Simulations-based models describing what happens at the atomic level are not straightforward, making it necessary to determine the initial conditions leading to the emergence of DBs. In a new paper publis...
