Engineers have created a new way to remove contaminants from storm water, potentially addressing the needs of water-stressed communities that are searching for ways to tap the abundant and yet underused source of fresh drinking water. The mineral-coated sand reacts with and destroys organic pollutants, providing a way to help purify storm water percolating into underground aquifers, creating a safe and local reservoir of drinking water for parched communities.

With threats of sea level rise, storm surge and other natural disasters, researchers are turning to nature to protect humans from nature. Using bioinspired materials that mimic mangrove trees, they are creating mangrove-like structures that can be used for erosion control, coastal protection, and habitat reconstruction. Structures like seawalls are expensive to build, raise environmental concerns, and obstruct the natural landscape. The prototype they have developed is scalable, smaller, simpler to use and cost effective.

Previously, researchers could only print this material, known as graphene, in 2D sheets or basic structures. But engineers have now 3-D printed graphene objects at a resolution an order of magnitude greater than ever before printed, which unlocks the ability to theoretically create any size or shape of graphene.

After an earthquake, hurricane, tornado or other natural hazard, it's considered a win if no one gets hurt and buildings stay standing. But an even bigger victory is possible: keeping those structures operational. This outcome could become more likely with improved standards and codes for the construction of residential and commercial buildings, according to a new report.

A team has found a way to prove the provenance of 3-D printed parts by embedding QR (Quick Response) codes in an innovative way for unique device identification. The researchers describe converting QR codes into 3-D features so that that they neither compromise the part's integrity nor announce themselves to counterfeiters who have the means to reverse engineer the part.

Researchers constructed integrated gene logic-chips called 'gene nanochips.' These self-contained nanochips can switch genes on or off according to the environment, where photo-reprogramming of the logic operation by UV irradiation is possible. Moreover, the researchers completed proof-of-concept experiments using artificial cells that produced the diagnostics and reactants (the desired RNA and protein) in a confined nanochip, suggesting the potential of autonomous nanochips in future medical prevention and care.

A team of researchers have developed a device that diffuses potent disinfectants for airborne delivery. The device works on a range of disinfectants that have never been atomized before, such as Triethylene glycol, or TEG. The team used the device to atomize disinfectants onto environmental surfaces contaminated with bacteria and showed that it eliminated 100 percent of bacteria that commonly cause hospital-acquired infections.
