Study experiments were conducted considering the temperature, time, and sample weight parameters in order to model dehydration by applying processes ulexite ores. Data obtained from of ore compared with TG analyzes. It was observed as result heat treatment that fastest water removal provided temperature range 150-250 °C it very low 400-750 °C. In design ANN method, 4 different models proposed s...
Boron nitride nanotubes (BNNTs), the structural analogues to carbon (CNTs), attracted considerable attention due their excellent properties. However, synthesis of BNNTs suffers from high-temperature requirement, which increases cost and adds complexity instruments (arc-discharge, plasma-assisted CVD, etc.), preventing further exploration use harmful chemicals (catalytic chemical vapor depositio...
Abstract: Soybean has shown increasing performance in terms of yield recent years. However, despite this growth, the lack quality control and knowledge about effects nutritional status plants compromised germination vigor a significant proportion seeds. The aim study was to evaluate physiological seeds root growth soybean cultivated with boron (B) sources different solubilities incorporated int...
The risk of resource depletion for future generations humanity is often cited as an important issue. choice impact categories and characterization models extraction in LCA no more precise than other models. This means that discussion needed on the use resources. In this article, potential Boron minerals (Colemanite, Ulexite, Tincal) are studied. These have a big role world Turkey; however, limi...
