Biopolymers obtained by Russian researchers with the help of hydrogen bacteria, are compatible with tissues of the organism and are autodestractive after a while. That makes such biopolymers indispensable for medical articles.
Polymers of microbe origin, or biopolymers, have recently drawn increasing attention of a great variety of specialists. These polymers have two important advantages. Firstly, they get destroyed in the environment and thus solve the contamination problem. Secondly, they are biocompatible, and consequently, they are not rejected by the organism when applied for medical purposes. The Krasnoyarsk and Moscow researchers from the Institute of Biophysics (Siberian Branch, Russian Academy of Sciences) and ??? “Biokhimmash” supported by the International Science and Technology Center are developing technology of biopolymer production and manufacturing of medical articles from them.
These are polymers of oxyderivative fatty acids, the so-called polyhydroxyalkanoates (PHAs). Some microorganism, for example hydrogen bacteria that get vital energy via oxidizing hydrogen, are able to synthesize PHAs. PHAs have a lot of advantages - their physicochemical characteristics, for example, thermoplasticity, is the same as that of polypropylene and polyethylene, and on top of that they possess antioxidant and optical properties and piezoelectric effect. Besides, like any biopolymers, they are compatible with tissues of organism and get destroyed in the environment. That is why they are promising for use in medicine (surgical and disposable materials), pharmacology (prolongation of drug action), food industry (packing and antioxidant materials), agriculture (seed obducers, destructible films).

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
