Method Shrinks Objects to the Nanoscale

Existing techniques for creating nano-structures are limited in what they can accomplish. Etching patterns onto a surface with light can produce 2D nano-structures but doesn’t work for 3D structures....

Anyone who skis, wears glasses, uses a camera, or drives a car is familiar with the problem: Coming into a humid environment from the cold causes eyewear, camera lenses, or windshields to...

A Northwestern University research team has developed tiny optical elements from metal nanoparticles and a polymer that one day could replace traditional refractive...

A new 3D printed device turns snowfall into electricity.

Fast-response, stiffness-tunable (FRST) soft actuators — or movable machine elements — were developed that could be used in soft robots.

Researchers, drawing inspiration from bacteria, have designed smart, bio-compatible microrobots that are highly flexible. Because these devices are able to swim through fluids and modify their shape...

Keck Telescopes Get a Motion Control Upgrade

In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea mountain summit has no nearby ranges to roil the upper...

Texas A&M professor Jaime Grunlan and his team are developing a new flame-retardant coating using renewable, nontoxic materials readily found in nature that...

NASA Langley Research Center has developed new methods for fabricating hollow nanoparticles using dendrimer molecules. Dendrimers are used as templates to control the size, stability, and solubility...

A heat-rejecting film was developed that could be applied to a building’s windows to reflect up to 70 percent of the Sun’s incoming heat. The film remains highly transparent...

Titanium is as strong as steel but about twice as light. These properties depend on the way a metal’s atoms are stacked but random defects that arise in the...

Intentionally “squashing”colloidal quantum dots during chemical synthesis creates dots capable of stable, “blink-free” light emission that is fully comparable...

Devices that convert AC electromagnetic waves into DC electricity are known as “rectennas.” MIT Researchers have demonstrated a new kind of rectenna, that uses a flexible...

Researchers from Drexel University say that adding MXene to silicon anodes could extend the life of Li-ion batteries by as much as five times. It’s...

Additive Manufacturing Using Infrared and X-Ray Imaging

Additive manufacturing is poised to liven the pace and scale of manufacturing. Deploying a range of techniques that use 3-D models to print objects layer by layer, it can generate a...

The diagnosis of diseases based in internal organs often relies on biopsy samples collected from affected regions. But collecting such samples is highly error-prone due to the...

Researchers have developed an imaging technique that uses a tiny, super sharp needle to nudge a single nanoparticle into different orientations and capture 2-D images to help...

To keep up with Moore's Law — an observation made in the 1960s that the number of transistors on an integrated circuit doubles about every two years — researchers...

Lightweighting design is an extensively explored and utilized concept in many industries, especially in aerospace applications, and is associated with the green aviation concept. The...

Titanium is as strong as steel but about twice as light. These properties depend on the way a metal's atoms are stacked, but random defects that arise in the...

Nanoscale Pillars Act as Memory Foam

A customizable nanomaterial was developed that combines metallic strength with a foam-like ability to compress and spring back. The material can store and release mechanical energy on the nanoscale, and...

Graphene may play a greater role in tomorrow electronics, thanks to an achievement from the Technical University of Denmark.

The quest to develop microelectronic devices with increasingly smaller size, which underpins the progress of the global semiconductor industry...

Ultrasensitive Chip-Based Sensors

An optical whispering gallery mode resonator was developed that can spin light around the circumference of a tiny sphere millions of times, creating an ultrasensitive, microchip-based sensor for multiple applications.

Existing nanosensor technologies depend on an external power source (typically a battery) to operate. Chemical and biological sensors based on nanowire or nanotube technologies exhibit...

Film Blocks Electromagnetic Interference

Electromagnetic interference (EMI) can harm smartphones, tablets, chips, drones, wearables, aircraft, and human health. EMI is increasing with the explosive proliferation of devices that generate it. A technique was developed to produce relatively low-cost EMI-blocking composite films.
