Kehilangan bag di LCCT KLIA

Semalam, aku kehilangan bag semasa mendarat dari Alor Setar sampai ke LCCT KLIA . Tak tahu lar perkhidmatan air asia ni, nak kena complain perkhimatan perkhidmatan yang sungguh teruk tidak seperti yang digambarkan dalam iklan, atau dah nama tambang murah, kena faham-faham aje lar, nak murah kena terima lar perkhimatan yang murah.

natijahnya, aku terpaksalah berpakaian t-shirt ini selama satu hari untuk menghadiri satu presentation yang penting untuk tempat kerja aku, demi survivor INEE di UniMAP.

Semoga berjaya

Nanostructured Porous Aluminium Oxide Thin Films Formed in Mixed Solution of H3PO4 and CH3COOH

A porous anodic aluminium oxide thin film formed on aluminum was prepared in a mixed electrolyte of phosphoric acid and acetic acid solution. The growth and morphology of the film were investigated. During the anodizing process, the growth of anodic aluminium oxide thin film is strictly influenced by the anodizing temperature. The anodizing process was done by varying the anodizing temperature from 5 °C to 25 °C. The constant anodizing voltage was applied at 130 V and the anodizing was done in the solution of H₃PO4 and CH₃COOH (H₃PO₄:CH₃COOH). The results indicate that the growth of anodic aluminium oxide thin was greater in temperature of 15 °C. Morphology of the anodic aluminium oxide thin film was examined by scanning electron microscope (SEM). Result indicates that at 15 °C to 20 °C, larger pore diameter was obtained. This study was explored the effect of anodizing temperature to the formation of AAO thin film in the anodizing process.
