ИЗУЧЕНИЕ СЕМЕННОЙ ПРОДУКТИВНОСТИ СОРТОВ ГОРОХА ОТЕЧЕСТВЕННОЙ И ИНОСТРАННОЙ СЕЛЕКЦИИ В УСЛОВИЯХ ЮГО-ЗАПАДА ЦЧР

The results of the study of vegetable pea collection of domestic and foreign breeding are shown. The biological characteristics and seed productivity of 23 varieties of vegetable pea in conditionof the southwest of Central Russia were studied. The varieties were selected based on the time of ripening. The cv. «Premium» is very early,ripening variety which showed the industrial ripeness at39 days and biological ripeness at 45 days. The cv. «Maksdon» has a higher seed productivity (2,54 t per ha).Приведены результаты изучения коллекции гороха овощного отечественной и иностранной селекции. Изучены биологические особенности и семенная продуктивность 23 сортов гороха овощного в условиях ЦЧР. Выделены сорта по группам спелости урожайности семян. Ультра ранним является сорт Премиум, у которого техническая спелость наступила на 39 сутки и биологическая на 45 сутки. По семенной продуктивности лучшие показатели у сорта Максдон – 2,54 т/га

Sonochemical Preparation and Subsequent Fixation of Oxygen-Free Graphene Sheets at N,N-Dimethyloctylamine-Aqua Boundary

In this study, the syntheses of oxygen-free graphene sheets and the method of its fixation at an oil-aqua interface were presented. The graphene sheets were prepared by exfoliation of synthetic graphite powder in an aqua-organic medium under ultrasound irradiation. N,N-Dimethyloctylamine- (DMOA-) aqua emulsion was used as the liquid medium, and pH was equal to 3. The obtained graphene nanosuspension was fractionated by sedimentation and decanted according to the weight. The graphene nanoparticle fractions, differing in configuration and number of layers, have been characterized using transmission electron microscopy (TEM), electron diffraction, HRTEM, Raman spectroscopy, and electron energy loss spectroscopy (EELS). It was found that using a DMOA-aqua mixture as the liquid medium in ultrasonic treatment of synthetic graphite leads to the formation of oxygen-free 1-2-layer graphene sheets attached to the DMOA-aqua interface. The proposed method differs from known ones by using a small amount of more environmentally friendly organic substances. It allows to obtain large quantities of oxygen-free graphene, and finally unconverted graphite can be directed for reuse. The proposed method allows to obtain both 2D graphene sheets with micron linear dimensions and 3D packages with a high content of defects. Both these species are in demand in areas related to the development of new materials with unique electrophysical properties
