The concerns about disease-causing bacteria that can live on skin, reside on food, and invade the body are ever increasing. The common and immediate reaction to these ’germs’ is to increase the dose of antibiotics and other drugs. However, as more cases of multidrug-resistant bacteria are occurring, the search for new compounds that can target these pathogens becomes more urgent. One place thes...

The constituents of honey's volatile compounds depend on the nectar source and differ depending on the place of origin. To date, the volatile constituents of Tualang honey have never been investigated. The objective of this study was to analyze the volatile compounds in local Malaysian Tualang honey. A continuous extraction of Tualang honey using five organic solvents was carried out starting f...

1. evaluate the adsorbability of polar/ionic pesticides and ionic degradates on activated carbon, 2. determine polar/ionic pesticide and ionic degradate breakthrough behavior in granular activated carbon (GAC) adsorbers, 3. develop recommendations for drinking water utilities regarding GAC adsorber design and operation parameters, and 4. evaluate different adsorption test methods in relation to...

The hydrophobic-amphiphilic self-assembly approach has been employed to prepare molecular micro-capsules simply by cooling down an emulsion, in a hot polar solvent medium, of a melted compound having two very well-distinguished units, both with highly non-polar and hydrophobic characteristics. The resulting micro-capsules are very stable and robust both in suspension and under dry conditions. F...

An understanding of the gas/particle-phase partitioning of semivolatile compounds is critical in determining atmospheric aerosol formation processes and growth rates, which in turn affect global climate and human health. The Study of Organic Aerosol at Riverside 2005 campaign was performed to gain a better understanding of the factors responsible for aerosol formation and growth in Riverside, C...

Samarium doped BiFeO3 compounds having nano-size crystallites were prepared by the ethylene glycol assisted sol-gel synthesis method. X-ray diffraction and SEM measurements as well Raman spectroscopy FTIR experiments used to clarify an evolution of crystal structure on microscopic local scale levels in formula Bi1-xSmxFeO3, where 0 = x ≤ 1. Magnetization along with structural data determine a c...

Polar organisms have been found to develop unique defences against the extreme environment environment, leading to the biosynthesis of novel molecules with diverse bioactivities. This review covers the 219 novel natural products described since 2001, from the Arctic and the Antarctic microoganisms, lichen, moss and marine faunas. The structures of the new compounds and details of the source org...
