3D-press seems not quite so surprising trend in the construction industry nowadays. It becomes a very important part in modern architecture, but it is difficult to assume and, what the extent of this “expansion” can achieve. It seems that the construction of the “fast” boxes low-rise buildings in Asia is unlikely to be limited to the case. A potential step forward was made a team of researchers UCA Berkeley headed by Associate Professor of Architectural Planning Ronald Reelem, who recently created a stand-alone pavilion called “Flower» (Bloom), to demonstrate the accuracy of the new cement powder based on the method of 3D-printed building.

We previously we reported on several 3D-printing architecture projects, including Castle Andrew Rudenko and impressive project Winsun, consisting of 10 buildings built in less than 24 hours.

However, the method that offered specialists Berkeley team is different from them, and instead displace wet cement, their technique involves printing out of thin layers of special dry cement powder, each then sprayed with water to result could be obtained fortified structure.

“Nowadays, there are some people who are experimenting with printing 3D-architecture, but only some of them are looking at 3D printing based on cement and related materials, with noteworthy. Even those who do prefer to displace the wet cement through a nozzle to produce a coarse structure, “says Reel, who is also a member of the authors’ conceptual project Cool Bricks.

The University of North Carolina (NC State) synthesized material for future plasmonic devices responsive to radiation in the middle infrared range. He was the first known materials provides effective work in this part of the spectrum, which opens up for him numerous applications ranging from high-performance computers, to solar and biomedical equipment.

The interaction of light with a new material based on the effect of the plasmon resonance. When light is incident on the interface between the conductor and the insulator, the electrons begin to oscillate in a conductor. The result is an intense electric field penetrating into the dielectric, which can be used for various applications.

The resonant frequency of the incident light is determined by the characteristics of the conductive material. Metals having a high density of electrons respond to short-wavelength ultraviolet range. Traditional semiconductors with lower density than the metal electrons have a resonance frequency corresponding to the far infrared spectrum. But the gap between the two wavelengths is still empty: scientists could not find materials with an efficient plasmon resonance in the mid-IR range.

NC State research team synthesized the desired material doped cadmium oxide rare earth elements dysprosium.

“Usually, when the doping material mobility of electrons is reduced. But in this case, we found the opposite effect – increase in the number of dysprosium this critical characteristics increase, “- noted in an article published on February 16 in the journal Nature Materials. Technically, the experiment showed that reducing the amount of doping dysprosium oxygen vacancies in the crystal CdO. These defects strongly scatter electrons and reduce their flexibility.

There are at least three practical reasons that make such a material is demanded in industry and science. Firstly, it allows to transform a part of solar electricity, typically leaving a loss. Secondly, will create more advanced technology molecular sensors for biology and medicine. And thirdly, to help develop a more rapid and effective device optoelectronics.
