A polyethylenimine adjuvant modified by mannose, which may be used in the study of vaccine adjuvant, was prepared this paper. Its structure characterized infrared spectroscopy and its micromorphology observed transmission electron microscopy. series mannose-modified polyvinylimine were according to molar ratio primary amine groups between mannose polyvinylimine, their storage stability at 4°C. ...

هدف از پژوهش حاضر بررسی تشریحی-تکوینی اندام های رویشی با تأکید بر کرک های اپیدرمی برگ مرزه بختیاری بوده است. برگ ها در چهار مرحله نموی بر اساس ابعاد و در ساقه نیز در دو میانگره بر اساس مکان انتخاب شدند. مطالعات بافتی و میکرومورفولوژیک با استفاده از میکروسکوپ های نوری و الکترونی نگاره انجام گرفت. تغییرات تکوینی در هر سه سیستم بافتی در اندام های هوایی مرزه بختیاری اتفاق می افتد. در طی مراحل تکوین...

Paleosols include soils formed under climatic condition different from the present. Although such soils are widespread in central Iran region, adequate investigations of them are yet to be carried out. Micromorphology is one of the most important tools in plaeoclimatological studies. This investigation was carried out to study microscopic features of two paleosols from Isfahan province to recon...

Cuticular waxes of Viscum album subspecies and of V. cruciatum have been examined for their micromorphology and chemical composition. Wax crystalloids occur preferably as irregular platelets and rodlets, while deviant structures are found in small areas. Among the triterpenoids forming the wax layer, oleanolic acid is prevailing with some 80%. The quantitative composition of the long-chain alip...

In this work, needle-like and micro-spherical agglomerates of nanocrystalline hydroxyapatite (HA) were successfully assembled on the surface of graphene sheets with the aid of dopamine having two roles, as a template and a reductant for graphite oxide during the process of self-polymerization. The crystalline structure and micromorphology of HA can be conveniently regulated by controlling the m...

The aim of this study was to design a simple and reliable method for obtaining the detailed information about the average size, size distribution, and the surface morphology of particles with variation of the sample preparation of a polymer emulsion. In this work, the characteristic features of the particles of rosin size with high viscosity were first described by scanning electron microscopy ...
