This is a 3D volume reconstruction of a forest of carbon nanotubes (CNT) embedded in epoxy, visualized using Amira. The TEM sample was prepared by focusing ion beam milling in a FEI Helios FIB and imaged in a Titan TEM using TIA's tomography suite. The tilt series was reconstructed using the SIRT algorithm on Inspect 3D. The reconstruction was then processed in an in-house software to identify CNT bundles and color them based on their size. This bundling information in key to understanding the network properties as well the axial mechanical properties of these composites.

This breathtaking flower-like structure actually marks the end of a polymer-aluminium oxide nanocomposite coating as it is the first sign of corrosion. The coating wasn't developed further as the "blooms of death" always came back and ultimately the whole coating failed already within 7 days.

Biochar is a highly porous carbon-rich material produced by pyrolysis of biomass. The SEM image shows micropores in a wood-derived biochar sample. Due to its unique properties such as high porosity, large surface area, and presence of negatively charged organic functional groups, biochar is used as adsorbent for the removal of various contaminants in soil and wastewater. Biochar is a simple yet powerful tool for soil and waste management, energy production, and C-sequestration to mitigate climate change.

Alginic acid is a heteropolysaccharide composed of D-mannuronic and L-guluronic acids. In nature it can be obtained from organisms as diverse as brown seaweed and bacteria. It is non-toxic, has a high molecular weight and a high viscosity. Due to its physico-chemical characteristics, it has been widely used as a phase stabilizer in food and beverages, as well as in the pharmaceutical industry. Another very important area of application is environmental protection: alginate gels are used as adsorbents for the removal of heavy metals such as cadmium, zinc, lead, chromium and mercury from wastewater. In the micrograph, Zinc crystals are observed that have been adsorbed on the surface of an alginate gel after being subjected to a process of wastewater treatment.

Aerators should be regularly kept cleaned or replaced.
The mesh in the aerator can collect lead debris, and then leach this toxic metal into the water passing through it.
Aerators cap the ends of most drinking-water faucets. In some cases, they’re used to conserve water by reducing a faucet’s maximum flow rate; in others their primary function is to concentrate the flow of water so that it delivers more pressure and cleaning power. But these little metal cages also collect debris. Including lead. And unless you’re regularly cleaning out those aerators, you might be developing a toxic mini gravel field through which your drinking water must pass before reaching your glass or coffee pot.
Indeed, one lead poisoning case in North Carolina involved a child (see link below):

Platinum can be deposited with electron beam lithography and a gas injection system. We also use a pattern generator to create and structure large areas. Here we patterned the Koch snowflake, which is designed by using only triangles in different sizes. Starting with a first large equilateral triangle then three triangles with only one third of its length are attached in the middle of each side of the first one. This was repeated several times. For demonstration the Christmas card was done with this procedure to show our users the capability of the system.

Carbon fiber or carbon fibre (alternatively CF, graphite fiber or graphite fibre) is a material consisting of fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms.
To produce carbon fiber, the carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fiber as the crystal alignment gives the fiber high strength-to-volume ratio (making it strong for its size). Several thousand carbon fibers are bundled together to form a tow, which may be used by itself or woven into a fabric.

It is an aberration corrected TEM image acquired from a multi-walled carbon nanotube filled with iron nanowire. This image is acquired by Dr. Mert Kurttepeli and Dr. Nadja Tarakina with an FEI Titan microscope operated at 120 kV equipped with an image correcter, a probe correcter and a monochromator. The image itself enables us to understand the interaction between the iron nanowire with the carbon nanotube and to see if there is any direct link between those two.
