A Geographical Study of Soil Characteristic in Sugarcane Cultivation of Rahuri Tahsil of Ahmedngar District (MS)

Sugarcane requires more water compare to other crops within growth periods. Its requires more water in summer season due to increases in temperature. Its growth is found successfully where the annual rainfall received 1400 to 2500 mm. pH in water is high (more than 8.1) is found in 21.72 percent villages. These villages come under canal and other source of irrigation. Less than 7.5 pH is found in 44 percent villages in the study area. EC in soil is suggested that it’s sufficient range in 25.54 percent villages. Calcium is existing less than 1.5 per kg/hr. is not sufficient for sugarcane. It is found high proportion (more than 3.1 per kg/hr.) in 37 percent villages in study area. Magnesium covered high ratio in 28 villages and chlorides is found on high ratio in 67 percent villages, which is affected on sugarcane growth

pH Dependent Molecular Self-Assembly of Octaphosphonate Porphyrin of Nanoscale Dimensions: Nanosphere and Nanorod Aggregates

Self-assembled nanostructures of zwitterionic octaphosphanatoporphyrin 1, of either nanoparticles or nanorods, depending on small changes in the pH, is demonstrated based on the J-aggregates. Porphyrin 1 self-assembled into nanosphere aggregates with a diameter of about 70–80 nm in the pH range 5–7, and nanorod aggregates were observed at pH 8.5. Hydrogen bonding, π-π stacking and hydrophilic interactions play important roles in the formation of this nanostructure morphology. Nanostructures were characterized by UV/Vis absorbance, fluorescence, atomic force microscopy (AFM) and transmission electron microscopy (TEM). This interesting pH dependent self-assembly phenomenon could provide a basis for development of novel biomaterials

STUDY OF METHODS INVOLVING COMPARISON OF SOIL SPECIMEN SAMPLES

Soil characterization methods including chemical analysis, mineralogy, spectroscopic and microscopic analysis are reviewed here. Soil differentiates in itself horizontally as well as vertically place to place by their different parent origin. These properties of soil are used for comparisons of specimens in forensic perspectives. Diverse characteristic of soil like colour, texture, granular size, density. crystalline structure etc. are supposed for analysis in these comparative study of soil specimens

A one-dimensional superstructure from the self-assembly of Ag nanoparticles induced by Cu2+ ion coordination

The self-assembly of spherical silver nanoparticles with variable size and controlled organization using triglycine as an organic template is described. Triglycine and silver nitrate were used as the starting materials for the preparation of the spherical nanoparticles, and in the presence of copper cations, the particles further self-assembled into one dimensional nanostructures

Kanamycin A 6 '-pyrenylamide: a selective probe for heparin detection

We have synthesized a novel derivative of kanamycin A bearing a pyrenyl fluorophore which can be used for the specific recognition of heparin in EtOH:H 2O (1:3) through formation of a 2:1 complex
