System for assembling and encapsulating of monolithic UHF chips Technology of low-temperature co-sintering ceramics (LTCC) is a high-technology inexpensive solution for assembling and encapsulating of monolithic UHF chips. Materials used at creation of such devices have to meet the requirements to low UHF losses: high strength and linear size tolerances, competitive prices. The article considers the Ferro A6 material system for the LTCC technology. The main physical and electrical characteristics are presented, comparison of different metallization systems (gold, silver, mixed) is given.

Systems for air purification in microelectronic production Different gases and chemical compounds are often used in technological processes of microelectronic production. The major part of these substances are aggressive and toxic, therefore their release into the atmosphere after treatment is forbidden. The issue of purification of the air used in the course of production is becoming a serious engineering problem requiring specific solutions and equipment.

Mechanical properties of carbon composite materials Carbon-fiber composites are the most promising materials for application in friction discs of aviation and car brake systems. Due to high strength and wear-resistance, enhanced thermal stability and other characteristics, these materials are actively replacing friction polymers and cermets used before.
The work presents results of investigation of the relief and local mechanical properties of carbon-carbon composite materials using the scanning nano hardness meter.

Microbicides with nanostructured polymer surface Аccording to estimates by the World Health Organization, at the end of 2008 there were about 33.4 million people with human immunodeficiency virus. The same year about 2.7 million people became newly infected, and 2 million people including 280 000 children died from acquired immunodeficiency syndrome (AIDS). The work presents a method of protection from viral infections with the help of nanomaterials-based microbicides, as altering nanostructures` characteristics, we can provide to materials new properties differing from the properties of the bulk material. The possibility of creation of microbicides using polymer nanostructured surface and nanoscaled carbon film is considered. Heterocycled derivatives of fullerene C60 are used as an additional possibility of controlling surface properties. It should be noted that the presented results have both scientific and social significance. It is shown that nanostructured polymers can be used to create microbicides, agents that can reduce the risk of HIV disease.

Clarifying antireflection nanocomposite coating Metal-dielectric heterogeneous composites possess optical characteristics vastly different from those usually found in natural materials. In a nanocomposite material with silver nanoparticles the small refractive index n<1.3 can be observed at low absorption, which allows to apply single-layer coatings on its basis to reduce reflection from light glasses, polycarbonate, PMMA and other optical materials with refractive index less than 1.7. In this article the design and calculated optical characteristics of such a coating are presented.

Useful model is really useful The article is intended for patent experts and designers. The title is such, because it is very important not only to set up a problem, but also to show ways of its solution. It is also necessary to reduce a gap between an patent expert and designer.
