Phys.org / Radiative cooling: Protecting ice from melting under sunlight, from iced food to glaciers
Ice plays a significant role in many aspects of life, ranging from food preservation to ice sports and ecosystems, thereby providing incentive to protect ice from melting under sunlight. Fundamentally, ice melts under sunlight ...
Phys.org / Switching plasmonic nanogaps between classical and quantum regimes
Quantum plasmonics is the study of quantum properties of light and its interaction with matter at the nanoscale. While intriguing, they are difficult to regulate on account of the lack of proper surface spaces to reversibly ...
Tech Xplore / Toward idealized thermal stratification in a novel phase change emulsion storage tank
Materials Scientists have shown how phase change materials can improve the energy density in thermal energy storage, although with limits relative to low charging/discharging speeds. In a new report now published in Elsevier's ...
Medical Xpress / Tailoring collagen-based biomedical materials
Collagen is a building block that can be hierarchically assembled into diverse morphological structures that are dynamically adaptive in response to external cues. Materials scientists have limited capabilities of guiding ...
Phys.org / Atomically crafted quantum magnets and their anomalous excitations
Quantum magnets can be studied using high-resolution spectroscopic studies to access magnetodynamic quantities including energy barriers, magnetic interactions, and lifetime of excited states. In a new report now published ...
Medical Xpress / Bone tissue engineering: Divalent metal cations stimulate new bone formation
The concept of new bone formation via divalent cations is widely reported although the underlying mechanism of the process remains unclear. In a new report now published in Nature Communications, Wei Qiao and a team of scientists ...
Phys.org / Bright, noniridescent structural colors from clay mineral nanosheets
In a new report now published on Science Advances, Paulo H. Michels-Brito, and a team of researchers in physics, inorganic chemistry, and physical chemistry in Germany and Norway, showed how bright non-iridescence structural ...
Phys.org / Garnet petrochronology: Revealing the lifetime and dynamics of magma at Somma-Vesuvius
Somma-Vesuvius is an iconic active volcano, with historic and archaeological records of hazardous eruptions. Geologists have conducted petrologic studies (microscopic studies of rocks) of eruptive products to provide insights ...
Phys.org / Superelasticity of a photoactuating chiral crystal
Superelasticity is an elastic response to an applied external force that occurs via phase transformation. The resulting actuation of the materials is an elastic response to external stimuli, including light and heat. While ...
Phys.org / Twin-field quantum key distribution (QKD) across an 830-km fibre
By using quantum key distribution (QKD), quantum cryptographers can share information via theoretic secure keys between remote peers through physics-based protocols. The laws of quantum physics dictate that photons carrying ...
Medical Xpress / Tissue engineered vascular grafts transform into autologous neovessels with biomimetic function
Tissue engineered vascular grafts (TEVGs) can advance surgical management of infants and children who require congenital heart surgery, by creating functional vascular conduits with growth capacity. In a new report now published ...
Medical Xpress / Enthesis strength, toughness, and stiffness: Comparing tendon insertions with varying bony attachment geometries
While tendons of the body differ dramatically in their function, mechanics, and the range of motion, they all connect to bone via an enthesis—a specialized interface that integrates tendon into bone. Effective force transfer ...
Tech Xplore / All-in-one flexible supercapacitor with ultra-stable performance under extreme load
Fiber-type solid-state supercapacitors can provide a stable power supply for next-generation wearable and flexible electronics. Typically, high charge storage and superior mechanical properties can be integrated into a single ...
Phys.org / Rainwater-driven microbial fuel cells for power generation in remote areas
In a new report now published on Royal Society Open Science, Mohammed Taha Amen and a team of scientists in bio-nanosystem engineering, chemical engineering and microbiology at the Chonbuk National University of South Korea, ...
Phys.org / Visualizing intracellular nanostructures of living cells using nanoendoscopy-AFM
Atomic force microscopy (AFM) offers a method for label-free imaging of nanoscale biomolecular dynamics to solve biological questions that cannot be addressed via other bioimaging methods including fluorescence and scanning ...
