Flexible optical design method for superconducting nanowire single-photon detectors
This research paves a way for realizing a high detection efficiency with an ultralow noise.
Nanofiber coating prevents infections of prosthetic joints
In a proof-of-concept study with mice, scientists show that a novel coating they made with antibiotic-releasing nanofibers has the potential to better prevent at least some serious bacterial infections related to total joint replacement surgery.
Hybrid nanostructures hold hydrogen well
Scientists say boron nitride-graphene hybrid may be right for next-gen green cars.
Researchers are upgrading an element by stretching it
In a project, researchers are exploring if there is a way to fine-tune germanium's physical properties, and thus improve its optoelectronic characteristics (how well it interfaces between electronics and light).
Disrupting the research process: changing materials science with robotics, AI and autonomy
The AFRL Materials and Manufacturing Directorate's Autonomous Research System, or ARES, can design, conduct and evaluate experimental data without human intervention, revolutionizing the materials research process as it is today.
Measuring the forces of biology
Biology, at the nitty-gritty level of motor proteins, DNA, and microtubules, takes its cue from physics. While much is known about the biological components that form the mitotic spindle, researchers are only beginning to explore the physical forces between those components.
Nano-decoy lures human Influenza A virus to Its doom
To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells. So researchers created the perfect decoy: A carefully constructed spherical nanoparticle coated in sialic acid lures the influenza A virus to its doom. When misted into the lungs, the nanoparticle traps influenza A, holding it until the virus self-destructs.
The quantum sniffer dog
A laser and detector in one: a microscopic sensor has been developed by researchers, which can be used to identify different gases simultaneously.
Quantum-dot solar windows evolve with 'doctor-blade' spreading
A research team demonstrates an important step in taking quantum dot, solar-powered windows from the laboratory to the construction site.
How to peel a bug: Engineering fast and effective antimicrobial killers
Scientists have engineered a new way to kill bacteria, and subsequently visualised in real time how the bacteria under attack were stripped of their protective membranes and died. These findings could provide a physical basis for designing more-effective antibiotics.
Talking speckles
The amount of light, passing through an opaque layer, can be enhanced using smart techniques. At the same time, the amount of reflected light diminishes, researchers now show. It's as if light speckles have a conversation of their own.
New tri-layer structure increases energy density in lithium batteries
Novel technique may lead to longer battery life in portable electronics and electrical vehicles.
New materials with photonic crystals that filter radiation
Researchers have proposed various designs of materials of a photonic crystal type that can be used to filter radiation. Specifically, the focus has been to develop a coating comprising dielectric spheres which if applied to a window, for example, would prevent the outside heat entering in the summer and the indoor heat from escaping in winter.
