Research ArticleOpen accessIn the abstractNanocrystalline Zn0.9Mn0.1S Thin Film: Case StudiesMohammad Syuhaimi Ab-Rahman, Noor Azie Azura Mohd Arif, Abang Anuar Ehsan, Sahbudin ShaariProblem statement: The high quality of ZnS:Mn nanocrystals is important in nanotechnology industries. The perfect chemical procedure is significant to produce the best of nanocrystals. Hence, this research is concern on the good chemical method in processing manganese doped zinc sulphide nanocrystals. Approach: For the first step, Mn doped ZnS nanocrystals were synthesized by using sol gel spin coating method. … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 8,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Diffusion Coefficient using Reversed-Flow Gas Chromatography-A ReviewKhalisanni Khalid, Rashid Atta Khan, Sharifuddin Mohd. ZainProblem statement: Since the earliest publication on the technique, Reversed-Flow Gas Chromatography (RF-GC) has been used to determine physicochemical properties by measuring the value of one in the presence of another. The method is precise, accurate and simple compared to other conventional techniques. Approach: The experimental setup consists of a small modification of a commercial gas chromatograph, so that it … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,227 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,193 accessesView PDFCite
