A Helical Aggregation Derived from a Conjugated Polymer with a Cylinder-Like Conformation
The formation of a cylinder-like helical conformation induced by chloroform was observed from a conjugated polymer, which was prepared by Knoevenagel condensation using N-octyl-3, 6-diformylcarbazole and p-phenylene diacetonitrile as the monomers. CD spectra and specific rotatory power measurements

A New Production Method of Submicron Alumina Powders
This paper describes a method for producing submicron high-purity alumina. In this method amorphous basic aluminum sulfate (BAS) was prepared by homogeneous precipitation of aluminum bisulfite solution containing chitosan. This cationic polymeric compound was used as an electrosteric dispersant.

A Schiff Base Nickel Complex. A New Material as Modifier for Selective Electrodes
There has been a considerable effort in recent years towards the preparation of new materials containing polyfunctional units (ligands) able to bind metallic ions. These complexes are studied to test their potential in the development of chemically modified electrodes for use in pollutant detection.

Abrasive Grain Efficiency and Surface Roughness Under Wheel-Loading on Machining Magnesium Alloys
Wheel-loading is one of the prime factors that determine the grindability of the grinding wheel. It can lead to an increase in grinding forces and grinding temperature to a level which causes deterioration in the surface integrity of ground samples.

Amorphous Carbon Thin Films Prepared by Electron-Gun Evaporation
Physical properties of amorphous carbon (a-C) thin films prepared by electron-gun evaporation on glass substrates have been studied. The electron gun method is a simple alternative technique to prepare films of this material, in vacuum or in controlled atmospheres like N2, with important physical pr
