Abstract

A criterion for estimating the homogeneity of materials for refractive X-ray optics from small-angle X-ray scattering data is proposed. A material of new type—nanoberyllium—is considered. A number of samples of beryllium materials, including commercial products, have been analyzed. The X-ray homogeneity of the materials is determined, as well as the influence of technological processes.

Abstract

Based on a global spatial mathematical model of the global carbon cycle in the biosphere, the change in environmental parameters caused by carbon dioxide emissions from fossil fuel combustion, deforestation, and erosion in African countries are calculated. The impact of deforestation and soil erosion due to inappropriate land use on climate change for African countries is calculated up to 2060.

5. Synthesis and properties of conjugates involving liposomes, a linear polymer, and the micelle of a polylactide-poly(ethylene glycol) block copolymer

Abstract

Multiliposome biodegradable conjugates have been obtained via electrostatic binding of a liposome-polylysine complex with micelles formed from a polylactide-poly(ethylene glycol) di- or triblock copolymer. It has been shown that the integrity of liposomes in conjugates is retained. Of special interest is a conjugate based on a polylactide-poly(ethylene glycol) diblock copolymer that exhibits stability in a physiological solution with 0.15 mol/L NaCl, but degrades in the presence of proteolytic enzymes. This fact allows the suggestion that the conjugate will be eliminated from the body after its transport function is completed. The results may be used to create biodegradable liposome containers for drug encapsulation and delivery.
