Volume 20 presents the latest Russian and Ukrainian research on the three principal crystallization methods: vapor, solution, and melt. Divided into three sections, chapters focus on heterostructure formation, growth from solutions, and the preparation of a homogeneous material during melt crystallization. Topics include the manifestation of macrodefects connected with the generation of twins in HgCdTe films, mechanisms that limit the accumulation of an impurity in front of a growth step, and a new method for preparing untwinned single crystals of certain high-temperature 1-2-3 superconductors.

"Every year when the deep cold of winter sets in, unbeknownst to humanity, dangerous visitors arrive from another world. Disguised as humans, the Nafikh move among us in secret, hungry for tastes of this existence. Their fickle, often-violent needs must be accommodated at all times, and the price of keeping them satisfied is paid most heavily by servs. Created by the Nafikh to attend their every whim, servs are physically indistinguishable from humans but for the Source, the painful, white-hot energy that both animates and enslaves them....Lucy is a serv who arrived as a baby and by chance was adopted by humans. She's an outcast among outcasts, struggling to find a place where she truly belongs....But when the body of a serv child turns up and Lucy is implicated in the gruesome death, the worlds she's tried so hard to keep separate collide. Hounded by the police, turned upon by the servs who once held her dear, she must protect her family and the life she's made for herself." --

L'analogie évoque plus souvent les figures de style ou les formes prélogiques de la pensée que la rigueur déductive du discours scientifique. L'ambiguïté dont elle est porteuse renvoie à la polysémie de la langue naturelle, et à une subjectivité dont la science cherche à se démarquer, tant elle aspire à constituer un langage universel. Pourtant, l'analogie intervient souvent dans les travaux de science, où elle "donne à voir" certains résultats théoriques sans recourir à une formalisation trop spécialisée.
