Polyoxometalate Based Organic-Inorganice Nanocomposites
Eurasian Chemico-Technological Journal, 2004 The organic-inorganic nanocomposites were synthesized by sol-gel techniques. The constructed film renders photochromism, which can be tuned by choosing suitable polyoxometalates (POM). The molybdenum POMs show better photochromism than the tungsten POMs,

Reversible low-light induced photoswitching of crowned spiropyran-DO3A complexed with gadolinium(III) ions. [PDF]
, 2012 Photoswitchable spiropyran has been conjugated to the crowned ring system DO3A, which improves its solubility in dipolar and polar media and stabilizes the merocyanine isomer. Adding the lanthanide ion gadolinium(III) to the macrocyclic ring system leads

Influence of oxygen pressure on the fs laserinduced oxidation of molybdenum thin films [PDF]
, 2018 We present a study of femtosecond (1028 nm, 230 fs, 54.7 MHz) laser processing on molybdenum (Mo) thin films. Irradiations were done under ambient air as well as pure oxygen (O2) at various gauge pressures (4, 8, 12 and 16 psi). Our results indicate that
