Three-dimensional direction-dependent force measurement at the subatomic scale
Osaka University and collaborators have developed a new atomic force microscopy (AFM) technique that can measure the three-dimensional force fields of atoms. In their technique, the precisely controlled tip of a mechanical arm is moved over a material surface at two different frequencies to provide information about the material surface in both vertical and parallel directions. This AFM technique will expand understanding of the structure and physical properties of material surfaces at the subatomic scale.

Scientists print nanoscale imaging probe onto tip of optical fiber
A team of researchers has developed a way to print a nanoscale imaging probe onto the tip of a glass fiber as thin as a human hair, accelerating the production of the promising new device from several per month to several per day. The high-throughput fabrication technique opens the door for the widespread adoption of this and other nano-optical structures, which squeeze and manipulate light in ways that are unachievable by conventional optics.

NIST physicists find a way to control charged molecules -- with quantum logic
National Institute of Standards and Technology (NIST) physicists have solved the seemingly intractable puzzle of how to control the quantum properties of individual charged molecules, or molecular ions. The solution is to use the same kind of 'quantum logic' that drives an experimental NIST atomic clock.

Exploring the conversion of heat to electricity in single molecules
Researchers at Osaka University investigated the influence of the geometry of single-molecule devices on their ability to produce electricity from heat. They fabricated devices consisting of a single molecule bridging gold electrodes and measured device electrical conductance and thermovoltage simultaneously. The devices with thiol-gold contacts displayed the highest thermovoltage when the gold-thiol bond was stretched, revealing that the thermoelectric performance of single-molecule devices can be modulated through geometry control.

New nanotechnology application for difficult-to-treat cancers
A new treatment combining shock waves with nanoparticles can successfully treat tumors that are difficult to target using conventional chemotherapy. This is the first time this combined therapy has been tested in live animals. The findings of this pre-clinical study, published in the journal Endocrine-Related Cancer, could lead to the development of more effective therapies for treating life-threatening cancers in the future.

'Hot' electrons don't mind the gap
Rice University scientists discover that 'hot' electrons can create a photovoltage about a thousand times larger than ordinary temperature differences in nanoscale gaps in gold wires. This finding opens a path for plasmonic tunneling-based photodetectors for sensors, solar cells and electronics.

Chemically tailored graphene
Graphene is considered as one of the most promising new materials. However, the systematic insertion of chemically bound atoms and molecules to control its properties is still a major challenge. Now, for the first time, scientists of the Friedrich-Alexander-Universität Erlangen-Nürnberg, the University of Vienna, the Freie Universität Berlin and the University Yachay Tech in Ecuador succeeded in precisely verifying the spectral fingerprint of such compounds in both theory and experiment.

Getting better drugs to market, more quickly
Getting better drugs to market faster, and at a fraction of the cost, is a step closer thanks to technology for speeding up the testing process, which is being developed by a Swansea University spin-out company, Moleculomics. They have been developing computer-generated models for protein structures in the human body. Using high-performance computing technology, they can run mathematical simulations to determine how these proteins interact with chemical compounds they are exposed to in real-life conditions.
