The mammalian olfactory system is highly complex, with more than 1000 non-specific binding receptors. The chemical diversity among these receptors yields differential responses resulting in a ‘fingerprint’ response pattern characteristic of a par

Two broad photoluminescence (PL) bands peaking near 502 and 725 nm are observed at room temperature in Ag-doped Li 2 B 4 O 7 crystals pre-irradiated at room temperature with X-rays. Their respective excitation bands peak near 297 and 325 nm. The requ
