Natural nanotechnologies
Some of the processes occurring in the environment and associated with migration of nanoparticles of metals can be considered as the natural nanotechnologies. Their detailed study will contribute to the future development of the industrial technologies, which are especially important for scarce and precious metals. As a priority it should highlight the problems of development of objects with nano gold. The discovery in Russia of a number of major gold deposits with so-called refractory ores requires significant improvement in the technology of their development. Presumably, some of the gold in them is represented by nanometer-sized forms of occurrence. One of directions of solving this problem is the study of natural processes of nano gold concentration. It turned out that it is directly connected with the problem of “new” gold origin.

Removing BPA from water through catalysts efficiently
Chemists have developed an approach that quickly and cheaply removes more than 99 percent of bisphenol A (BPA) from water. BPA, a ubiquitous and dangerous chemical used in the manufacturing of many plastics, is found in water sources around the world. Concerns over BPA’s health effects prompted manufacturers to start making BPA-free products like baby bottles and water bottles starting in 2010. Ironically, many BPA replacements also have similar toxicity to BPA itself.

A creation of current research: Bio-compatible ion current battery
ENGINEERS in the US have developed a new form of battery which works on the basis of flowing ions, rather than flowing electrons, the same kind of electrical energy used by living organisms. In a conventional battery, ions move from one end of the battery to the other, with the current moving as a flow of electrons. In the new battery, this is reversed, with the electrons moving from one end of the battery to the other and the current moving as a flow of ions. This is the same type of signal that powers muscles, nerves and regulates the rhythm of the heart. The electron current in a conventional battery requires ‘patching’ into the ionic current in living organisms, but this is very difficult due to the much higher voltage of an electron current. Being able to directly connect ion current battery devices into living systems could have a wide range of applications.

Chemical route towards electronic devices in grapheme
The ‘wonder material’ graphene has many interesting characteristics, and researchers around the world are looking for new ways to utilize them. Graphene itself does not have the characteristics needed to switch electrical currents on and off and smart solutions must be found for this particular problem. “We can make graphene structures with atomic precision. The electronic properties of graphene can be controlled by synthesizing it into very narrow strips (graphene nano ribbons). Previous research has shown that the ribbon’s electronic characteristics are dependent on its atomic width. A ribbon that is five atoms wide behaves similarly to a metallic wire with extremely good conduction characteristics, but adding two atoms makes the ribbon a semiconductor.
