Tracking major sources of energy loss in compact fusion facilities

Analysis of energy loss in low-aspect ratio tokamaks opens a new chapter in the development of predictions of transport in such facilities.

Plot twist: Straightening single-molecule conductors improves their performance

Researchers have synthesized nanowires made of a single molecule of oligothiophene up to 10 nanometers in length. By forcing the molecular chain to adopt a planar conformation, they were able to significantly enhance its electrical conductivity. The findings have many potential applications for consumer electronics, especially OLED TVs and smartphone screens.

Using a selective light absorber to build a photothermal catalysis system

Researchers at Hebei University in China and Hakkaido University in Japan have recently used a selective light absorber to construct a photothermal system that can generate temperatures up to 288°C under weak solar irradiation (1 kW m-2). This system, presented in Nature Communications, achieved a temperature three times higher than that generated by traditional phototermal catalysis systems.

Direct atom-resolved imaging of magnetic materials

In conventional electron microscopes, performing atomic-resolution observations of magnetic materials is particularly difficult because high magnetic fields are inevitably exerted on samples inside the magnetic objective lens. Newly developed magnetic objective-lens system provides a magnetic-field-free environment at the sample position. This enables direct, atom-resolved imaging of magnetic materials such as silicon steels. This novel electron microscope is expected to be extensively used for the research and development of advanced magnetic materials.

Tiny light box opens new doors into the nanoworld

Researchers have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery opens up new possibilities in the world of nanophotonics.

Light-powered nano-organisms consume carbon dioxide, create eco-friendly plastics and fuels

Researchers have developed nanobio-hybrid organisms capable of using airborne carbon dioxide and nitrogen to produce a variety of plastics and fuels, a promising first step toward low-cost carbon sequestration and eco-friendly manufacturing for chemicals.

Changes in pressure, more so than temperature, strongly influence how quickly liquids turn to gas

It's a process so fundamental to everyday life—in everything from your morning coffeemaker to the huge power plant that provides its electricity—that it's often taken for granted: the way a liquid boils away from a hot surface.

A bubbly new way to detect the magnetic fields of nanometer-scale particles

The method provides manufacturers with a practical way to measure and improve their control of the properties of magnetic nanoparticles for a host of medical and environmental applications.

A new candidate for dark matter and a way to detect it

Two theoretical physicists at the University of California, Davis have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference in Granada, Spain and it has been submitted for publication.

Researchers 'stretch' the ability of 2D materials to change technology

Two-dimensional (2D) materials -- as thin as a single layer of atoms -- have intrigued scientists with their flexibility, elasticity, and unique electronic properties. Now, researchers have combined 2D materials with oxide materials in a new way, using a transistor-scale device platform, to fully explore the capabilities of these changeable 2D materials to transform electronics, optics, computing and a host of other technologies.
