1. Scientists were making the first observations and size measure- ments of nanoparticles during the first half of the 20-th century. We asso- ciate those observations with the name of Zsigmondy who made detailed studies of some nanomaterials with sizes down to 10 nm and less. He had used ultramicroscope that employed a dark field method for seeing par- ticles with sizes much less than light wavelength before new microscopes appeared. Scientists widely applied some traditional techniques for first generation passive nanomaterials. 2. The Nobel Committee awarded the American scientists the Nobel Prize for developing and implementing molecular beam epitaxy (MBE) as a research tool. Due to MBE scien- tists lay down automatically-precise layers of atoms and, in the process, build up complex structures. 3. Creating devices smaller than 100 nano- metres opens many doors for the development of new ways to capture, store and transfer energy. People have already begun the search of ways utilizing nanotechnology for the development of consumer products.

Dear Ann,

    Thank you for your letter. I 'm happy to receive it!

    You want to know what kind or music I listen to. I'd like to tell you that music is my hobby and I'm fond of pop music. I have got a wonderful collection of CDs at home. Besides, my preferences depend on my mood.

Sometimes I like to listen to romantic and calm music. Other day I prefer energetic dance music. As for my favourite singer, he's Dima Bilan. His songs are so wonderful! You're interested in my parents' attitude towards my music preferences. They share my interests and we often discuss songs or music video.

    Write back soon!    

    Best wishes,

    Elina

I think the Motherland is one of the greatest values in our life. We do not choose which country to be born in, but our moral duty is to love and protect it in order to inherit our children.

Firstly, the Homeland is not just the country in which you were born, but also the spiritual heritage of the people: language, culture, mentality, traditions and customs. In each family that is consciously related to these values, folk songs are played, holidays are celebrated and a folk spirit reigns. People strive to get to know their country, visiting not only famous places to see the sights, but also every corner of it.
