Directly visualizing hydrogen bonds

Using a newly developed, ultrafast femtosecond infrared light source, chemists have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules - the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.

Thermoelectric nanomaterials for future green tech devices

Thermoelectric devices, which convert heat to electricity and vice versa, can harness that wasted heat, and possibly provide the green tech energy efficiency that's needed for a sustainable future. A new study shows how porous substances can act as thermoelectric materials - pointing the way for engineering the use of such materials in thermoelectric devices of the future.

Novel method for growing high-quality oxide thin films on a glass substrate

Researchers succeeded in growing thin film crystals consisting of highly oriented crystal grains, which were as large as a few micrometers or more, by coating a glass substrate with oxide sheets of about one nanometer in thickness, called oxide nanosheets, and using these nanocrystals as seed crystals in solid phase crystallization.

Science journalists pen Copenhagen Declaration on nanotechnology

The science debate of the European Science Journalists EUSJA revealed many severe misunderstandings and a profound lack of knowledge about nanotechnology, two decades after the topic first emerged. More detailed information and more dialogue is necessary, in particular a broader array of inclusive, participative and collaborative formats, above all in the early phases of research.

A Swiss cross made of 20 atoms

The manipulation of atoms has reached a new level: Physicists were able to place 20 single atoms on a fully insulated surface at room temperature to form the smallest 'Swiss cross', thus taking a big step towards next generation atomic-scale storage devices.

Researchers find nanoscale revolution biomotors in many bacteria and viruses

Researchers reported the discovery of a new class of biomotor, unique in that it uses a 'revolution without rotation' mechanism. Rotation is the turning of an object around its own axle, as the Earth does every 24 hours. Revolution is the turning of an object around a second object, as the Earth does around the sun.

The world's first photonic router

Scientists have demonstrated for the first time a photonic router - a quantum device based on a single atom that enables routing of single photons by single photons. This achievement is another step toward overcoming the difficulties in building quantum computers.

Using light to modulate the properties of a copper-based superconductor

Researchers used a technique based on applying short flashes of light to observe and analyse the features of a superconductor at high critical temperature, a material with major prospects for technological applications. In addition to providing an explanation for the peculiar behaviour of the material, the study also opens to the possibility of controlling its characteristics by means of laser pulses.

Nanotechnology fabrication - from stronger Kevlar to better biology

Place two large, sturdy logs in a streambed, and they will help guide the water in a par­tic­ular direc­tion. But imagine if the water started mim­ic­king the rigidity of the logs in addi­tion to flowing along them. That's essen­tially what hap­pens in a directed assembly method devel­oped by a researcher at Northeastern University.
