Composites That Self-Heal at Low Temperatures
The researchers obtained a healing efficiency of over 100% in a glass fiber-reinforced laminate at temperatures of -60° Celsius.
"Phase Separation" in Oxides Could Produce a Multifunctional Chip
The ORNL proof-of-principle experiment shows that phase-separated materials could be a way beyond the “one-chip-fits-all” approach.
Oxybenzone Damages Reefs
Researchers have found oxybenzone concentrations in some Hawaiian waters at more than 30 times the level considered safe for corals.
Asphalt-Based Carbon-Capture Technology Advances
A new form of asphalt can sequester 154% of its weight in carbon dioxide at high pressures that are common at gas wellheads.
U.S. Navy Developing High-Tech Bandage
The bandage will be lightweight, keep the wound fresh and maintain tissue condition for up to 72 hours.
Nutrient Pollution Is Changing Sounds in the Sea
The demise of biological sounds is likely to have negative impacts on the replenishment of fish populations.
Nanomaterial Shields Devices from Interference
A several-atoms-thick titanium carbide film can be effective at blocking and containing electromagnetic interference and can be applied easily as a coating by spraying it onto any surface.
Etching Process Bonds Metals to Almost Any Surface
Through the etching process, a 3D structure with tiny hooks is created.
Aerosol Emissions Driven by Consumption
Because aerosols emitted through industrial production or fossil fuel burning typically remain in the atmosphere for short periods, their influence on climate is strongest where they are emitted.
A More Accurate Test for Lead Paint
The new test consists of a vial that holds paint thinner and a sprinkling of certain salts that, when combined with the right concentration of lead, form a gel.
Improved Thin-Film Microelectronics
The team demonstrated room-temperature deposition of silicon and gallium nitride—linchpin elements in many advanced microelectronics.
Alternative Nuclear Detection Material
Researchers have developed hexagonal boron nitride semiconductors to detect the neutron signals that help identify the presence of nuclear materials.
Stretchy Micro-Supercapacitors Could Power Soft Robots
Supercapacitors have remained rigid and are thus a poor fit for soft materials that need to be able to elongate.
Spider Silk Used to Create Microscope Superlens
Superlenses offer the potential to allow viewing beyond current magnification limits.
Anode Boosts Charge Capacity of Batteries
In addition to tripling the charge capacity offered by graphite, the silicon-tin nanocomposite is extremely stable over many charge-discharge cycles, essentially extending its useful life.
Polymer Solar Cells One Step Closer to Mass Production
Using a mock-up of a roll-to-roll processing method, the researchers produced polymer-based solar cells with a power conversion efficiency of over 9.5%, just shy of the commercial target of 10%.
Timber-Concrete Composite Safe for Construction
While timber-concrete systems have been in use in Europe since the 1990s, they are only now being looked at in the U.S.
Biosensor Allows for Early Detection of Prostate Cancer
The biosensor's high sensitivity makes it capable of early detection of the molecules that are produced by the cancer that pass into the bloodstream.
Transparent Wood Provides Lighting and Insulation
Transparent wood provides better thermal insulation and lets in nearly as much light as glass, while eliminating glare and providing uniform and consistent indoor illumination.
Oil Well Fissures Plugged with Bacteria
Typically, well leaks are repaired using cement. But sealing small fissures is difficult because of cement's high viscosity.
