Ultrashort optical pulses are becoming more and more relevant in a number of applications including distance measurement, molecular fingerprinting and ultrafast sampling....

In biology, there are many examples where light induces movement or change — think of flowers and leaves turning toward sunlight. Magnetic elastomeric composites were developed that move in different...

Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with...

3D printing allows for the efficient manufacture of complex geometries. A very promising method is direct laser writing in which a computer-controlled focused laser beam acts as a pen and produces the...

The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface...

It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...

The Create the Future Design Contest was launched in 2002 to help stimulate and reward engineering innovation. In the past 16 years, the annual contest has drawn more than 13,000 product...

Cellphones, laptops, tablets, and many other electronics rely on their internal metallic circuits to process information at high speed. Current metal fabrication techniques...

A new method increases the service life of concrete structures by reducing the infiltration rates of deleterious ions. The key is a nano-sized additive that slows down penetration of...

Colloids — insoluble particles or molecules anywhere from a billionth to a millionth of a meter across — are so small they can stay suspended indefinitely in a liquid or even in air. Robots about...

Current density is the amount of electrical current per cross-sectional area at a given point. As transistors in integrated circuits become smaller and smaller, they need higher and higher...

Fabricated using inexpensive and widely available organic pigments used in printing inks and cosmetics, an artificial retina was developed that consists of tiny pixels like a digital camera sensor on...

INVISIBLE GLASS

Brookhaven National Laboratory’s Center for Functional Nanomaterials (CFN) has developed a method for creating surface nanotextures that effectively...

DON’T MELT. MELD.™

The MELD™ technology enables additive manufacturing (AM) of metals. This patented process is unique because there is...

AEROGELS FROM ENVIRONMENTAL WASTES FOR NOVEL ENGINEERING APPLICATIONS

Associate Prof. Hai Minh Duong and Prof. Nhan Phan-Thien, National University of...

A technique that enables on-demand control of composite behavior could enable a variety of new capabilities for future rotorcraft design, performance, and maintenance. The focus of the research was on...

When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....

Photons, or units of light, are faster than electrons and could, therefore, process information faster from smaller chip structures. A switch was designed that bypasses a...

A device and method have been developed to conduct compression and tensile tests on soft materials such as flocculated sediments, biopolymers, biological materials, and food stuffs. The device...

The measurement of mechanical behavior in very small samples whose dimensions are on the order of microns and below can offer advantages over conventional macroscopic testing in many instances. Motivations for investigating...

To further develop semiconductor technology, the field of molecular electronics is seeking to manufacture circuit components from individual molecules instead of silicon. Because of...
