Pure metal nanowires (NWs) are nanomaterials with distinctive properties that make them useful for various applications. However, their utilization in modern electronics has been limited by the lack of a mass-production method. Researchers have now succeeded in the mass growth of aluminum NWs. The underlying growth process could in principle be extended to other metals

Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For comparison, Earth is approximately 26,000 light-years from the center.) Astronomers have directed NASA's James Webb Space

When cars, planes, ships or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced. A research group is now presenting an advance in so-called massless energy storage -- a structural battery that could halve the weight of a laptop, make

Physicists have created the first two-dimensional version of the Bose glass, a novel phase of matter that challenges statistical mechanics. Physicists from the Cavendish Laboratory in Cambridge have created the first two-dimensional version of the Bose glass, a novel phase of matter that challenges statistical mechanics. The details of the study have been published in

Researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal 'metasheet' but, with a jolt of electricity, morph into preprogrammed 3D shapes and crawl. Cornell University researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal "metasheet" but, with

Astronomers have achieved a major breakthrough in solar physics by successfully producing detailed maps of the Sun's coronal magnetic fields. This milestone promises to enhance our understanding of the Sun's atmosphere and how its changing conditions lead to impacts on Earth's technology-dependent society. The corona, or the Sun's outer atmosphere, greatly influences solar winds and

Researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient -- it still functions even after being pierced several times and then stretched 2,000 times. One

Researchers have succeeded in combining two major research fields in photonics by creating a nano-object with unique optical qualities. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices. Researchers at Chalmers University of Technology

Water polluted with heavy metals can pose a threat when consumed by humans and aquatic life. Sugar-derived polymers from plants remove these metals but often require other substances to adjust their stability or solubility in water. Now, researchers report a sugar-like polymer that traps heavy metals within insoluble clumps for easy removal. In proof-of-concept tests

For the design of reliable power grounding systems for critical electrical infrastructure, soil resistivity investigation is crucial. However, soil resistivity depends on various geotechnical properties, necessitating the need for robust assessment methods. In a new study, researchers conducted a comprehensive investigation into the behavior and relationships between soil resistivity and key geotechnical parameters and developed

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged antimatter positron. It is naturally very short-lived, but researchers have now successfully cooled and slowed down samples of positronium using carefully tuned lasers. They hope this

A research team developed a microbial strain that efficiently produces aromatic polyester using systems metabolic engineering. Among various eco-friendly polymers, polyhydroxyalkanoates (PHA) stand out for their excellent biodegradability and biocompatibility. They decompose naturally in soil and marine environments and are used in applications such as food packaging and medical products. However, natural PHA produced to
