A method for detecting mercury (Hg) ions in an aqueous solution is described. The method includes contacting the aqueous solution with a chemosensor to form a mixture; and monitoring a change in a fluorescence emission profile of the chemosensor in the mixture to determine the presence or absence of Hgions in the aqueous solution. The chemosensor includes pyrene silica nanoparticles where at least one pyrene is bonded to a surface of a silica nanoparticle through an amide bond with a formula of, pyrene-C(&#x2550;O)NHR-silica nanoparticle, and where R is an alkyl chain.

Oil spill detection is crucial, both from an environmental perspective and the associated economic losses. Current optical oil sensing techniques, such as underwater microscopy and light scattering methods, mainly focus on detecting the properties of particles or organisms in water and often require costly equipment and sophisticated data processing. Recent studies on graphitic foam show its extraordinary pollutant absorbing properties, with high absorption weight ratios. Here we propose to produce a graphene foam based ultra-light material that changes its optical properties on absorbing oil species. The results demonstrate clear changes in optical transmission and scattering properties of graphene foam when exposed to various oils. The effective graphene foam sorbent can be easily integrated with optic fibers systems to detect the optical property variations and also to monitor oil presence/spillages remotely. Such sensors can also be used for underground oil exploration.

A simple one pot sol-gel method for the synthesis of bi-metal nanostructures is based on non-noble metals (Fe, Co and Sn) and titanium. The method involves the synthesis of mixed metal nanoscale composites using low cost precursors which allow for the synthesis of desired nanocomposite materials with self-scarifying titanium or silica supports. The procedure does not require any surfactant or any need for pH controlled step. Applicants' method involves the in-situ generation of precursors and their simultaneous entrapment in a gel. This simple one pot synthesis allows for the synthesis of homogenous size, shape and distribution of targeted nanostructures. Further, this method can be applied for the preparation of various nanocomposite materials using different choices of metals and self-scarifying supports. Applicants also show that Pd, the noble metal based nanocomposite is feasible.
