This paper reviews the applications of focused ion beam (FIB) sputtering for micro/nano fabrication. Basic principles of FIB were briefly discussed, and then empirical and fundamental models for sputtering yield, material removal rate, and surface roughness were presented and compared. The empirical models were more useful for application compared
Moulds growth in indoor environments has been of concern in the built environments,particularly in the hospital environment. Several studies have shown direct correlation between the exposure to moulds growth and copious adverse health effects. The Air-Conditioning systems in the hospital environments are tasked to provide comfortable environmental
Fiber and free-space practical decoy state quantum key distribution has been simulated for both BB84 and SARG04 protocols. The numerical simulation has shown that the fiber based QKD and free space QKD systems using the proposed method for BB84 are able to achieve both a higher secret key rate and greater secure distance than that of SARG04Eur. Phy
This paper discusses the comparison of micro machining process using conventional and micro wire electrical discharge machining (WEDM) for fabrication of miniaturized components. Seventeen toothed miniaturized spur gear of 3.5 and 1.2 mm outside diameter were fabricated by conventional and micro WEDM respectively. The process parameters for both co
Biodegradable poly(butylene succinate)/carbon nanotubes nanocomposites were prepared by melt mixing process and the influence of carbon nanotubes on the properties of the nanocomposites was investigated. Differential scanning calorimetry showed that crystallization temperature (Tc) increase with increasing carbon nanotube content. Improvement of te
This work investigated the influence of two FIB process parameters, (i) acceleration voltage, (ii) dwell time with respect to milled depth. The response variable was average surface roughness (Ra). Statistical models of responses were developed using Taguchi method of design of experiment. Signal to noise ratio were calculated and analyzed for all
The interpretation of the texts of the Qur’Én regarding the rights, role, and status of women is a challenge and much debatable subject. The Qur’Én is seen by almost all Muslims as the literal words of Allah (swt). The majority Muslim exegetes interpreted the verses of the Qur’Én by applying a method of literal reading. In modern context,
Aging causes a regression of physiological function. Complaints of declining memory are common with advancing age. Gingko extracted from leaves of Gingko biloba (maidenhair tree) has neuroprotective properties against memory dysfunction and neuronal death in Alzheimer's disease. The objective of this study was to determine the public awareness
