    The setup allows you to apply aseptic, antibacterial, and antiviral structures of nanomaterials (silver, copper, etc.) by vacuum-plasma spraying. The unit is delivered together with a patented and technology process. The user receives a machine for innovative textile materials production.

          The scope is very wide: from hygienic and antiviral masks to special innovative clothes and protective suits, air filters etc.

​

Technological process 

     

         The technological process is based on a patented technology for applying silver (and other metals) onto a textile surface. PVD methods of atomization of the material make it possible to achieve very small sizes of silver particles (5-20 nm), high particle concentrations and, as a result, a significant increase in the activity of metals (bactericidal, antiviral and fungicidal effects).

       At the same time, vacuum-plasma technology allows you to save the original properties of textiles:

- avoidance of changes in its structural composition (which is not available for chemical methods of silver deposition);

- avoid overheating of textiles during processing due to the use of “cold” plasma (textile temperature does not exceed 80 C);

- high stability of silver nanoparticles in the structure of textiles.

​

         Moreover, chemical processing methods for fabrics with silver are not eco-frendly, in contrast to the proposed vacuum-plasma approach.

​

Key characteristics

• The substance of functional nanosilver> 1 mg / l

• Silver nanoparticle size - 1-10 nm

​

​

A unique project Silver-mask.ru was implemented on the prototype of the installation that was made by our team.

​

Production time: 6-12 months.

Competitive advantages of innovative aseptic textiles:

• Protection against bacterial transfer;

• Permanent antimicrobial effect;

• Reducing the risk of contact infection;

• Prevention of unpleasant odors caused by bacteria;

• Health safety (lack of metal salts, formaldehyde, arsenic);

• Lack of allergic reactions;

• Resistant to sterilization.

A device for the precise positioning of x-ray optical elements

Трасфокатор

          The main feature of this solution is a positioning of standard x-ray optical elements (12 mm in diameter and up to 3 mm thick) with high precision (better than 5 μm) in the x-ray beam.

​

          The device is intended for instrumental focusing and control of the parameters the x-ray flux in the synchrotron radiation channels, laboratory analytical and measuring systems of non-destructive measurements of complex structures and objects.

​

          The most interesting feature of the system is the ability of x-ray lens individual insertion in arbitrary order (e.g. 1, 5 and 64 or 1,2,3,4 lens might be inserted, the order is user-defined)

​

           Also, a clear advantage is the compact size of the device and the high accuracy of lenses positioning.

Key parameters for 64-lenses device:

  1. Compactness (dimensions up to 420 x 350 x 350 mm (LxWxH))

  2. Light weight (with vacuum chamber - less than 40 kg)

  3. Vacuum compatible version - HV, UHV (on request)

  4. High repeatability of lens positioning in the beam (+/- 2.5 μm)

  5. Ability to individually inserting one lens per cycle into the x-ray beam in the given order

  6. Possibility of a step change in the focal length of the optical system

  7. Minimal working distance (from first lens to sample - less than 50 mm).

  8. System for any number of x-ray optics elements (from 10 pcs.)
