Carbon foams can be readily made by thermal decomposition of organic material such as sucrose under vacuum at high temperatures. Foams created this way typically consist of cells of glassy carbon separated by very thin (<50 nm) carbon membranes. When they cool down to room temperature, these membranes often break and buckle due to thermal stresses, giving rise to the structure in the image.

The first image shows the reconstruction of a schmidingerothrix salinarum cell. The microbe was milled with a Helios 650 NanoLab FIB. An image was taken from each slice. With the help of the software Amira over 500 images were aligned and the different elements of the cell were assigned different colors. The cell’s outer membrane is shown in red, the cell nuclei are green and purple, the alveolar sheets are turquoise and bacteria inside the cell are yellow with a vacuole in blue.

The image represents actually a big defect (in a cutting tool) in which a cast iron shaving has solidified during the machining of a motor block work piece.
During metal cutting, cracks are generated at the cutting edge of the insert tool due to the severe thermo-mechanical loading. Besides, high temperature causes the melt of metal chips, which have in this case taken the shape of the big crack after solidification.

Using supercomputers and data mining, a team led by engineers at UC San Diego has discovered and developed a new phosphor to make LEDs with excellent color quality. Under UV light, the phosphor emits either green-yellow or blue light depending on the chemical activator that is mixed in.
Researchers published the new phosphor on Feb. 19 in the journal Joule.

Colloidal gold nanoparticles have been used for centuries by artists due to the vibrant colors produced by their interaction with visible light. More recently, these unique optical-electronics properties have been researched and utilized in high technology applications such as organic photovoltaics, sensory probes, therapeutic agents, drug delivery in biological and medical applications, electronic conductors and catalysis. The optical and electronic properties of gold nanoparticles are tunable by changing the size, shape, surface chemistry, or aggregation state.

An electrochemical cell made with a 3-D printer for studies using high-energy X-rays. This would take five to six months longer to make in aluminum, be cost-prohibitive and difficult to machine in a mix of metal and nonconductive material. The polymer-based sample holder can maintain a flow of electrodes, temperature and charge in the chamber while the holder is angle in the beam to gather different scattering patterns. Scientists working with the Advanced Photon Source at Argonne National Laboratory can conduct studies remotely by sending in these filled sample holders. The black tape represents a glassy carbon electrode. The amber film prevents X-ray scattering and serves as a window to isolate the sample environment. May 2014.

Phones and computers have come a long way since the 1950s - so that a smartphone in your pocket is far more powerful than the 1953 30-ton behemoth called ENIAC.
The magic technology that makes this possible is the silicon transistor. But we can't keep up this pace of shrinking them forever - as they get smaller, transistors get less efficient and start to leak power as heat. Sooner or later the reign of transistors has to end.
Argonne scientists are hard at work on basic research on a number of technologies that could lead to the next transistor. Read more »

A paramount issue impacting the performance, safety, and life extension of current light-water reactors is the environment-induced cracking of metallic structural components. Understanding their structure and chemistry, as well as how they react to various aqueous environments, is important to determining their real-world behavior. Metallography is one of the tools in determining microstructure. Using a light etching technique, the crystallographic orientation of the metal can easily be observed. This scanning electron microscopy image taken in backscatter mode illustrates how crystallographic pits are formed on the metal surface when exposed to acid. Imagery provided by PNNL researcher Matthew Olszta. Other contributors are Robert Seffens, Clyde Chamberlin, Mychailo Toloczko and Stephen Bruemmer. Image colored by PNNL graphic designer Jeff London.
