White light, white heat: A soft-chemistry synthesis of GeO, based on the thermally induced dehydration of Ge(OH)2, enables its thermal disproportionation to give size-controlled germanium nanocrystals (ncGe), which exhibit a pronounced size-dependent photothermal effect, superior to that of silicon nanocrystals … Continue reading →

Chinese students from Ozin group, Chenxi Qian and Wei Sun (last-year recipient) were awarded highest honor by the Chinese government at the Chinese Consulate General Toronto. Geoff praised his students and gave a speech about his views on Chinese students … Continue reading →

Size separated lipophilic silicon nanoparticles that fluoresce from red to infrared are encapsulated into liposomes and delivered to cells. Specific particles are found to encapsulate better into the liposomes and thus enhance cellular uptake and toxicity when delivered to cancer … Continue reading →

This review article, published in Advanced Materials provides a comprehensive overview of pioneering research, present day activities and future directions aimed at enhancing the harvesting of sunlight, by exploiting the unique properties of slow photons in photonic crystal materials. The … Continue reading →

Geoff’s latest opinion editorial published in Advanced Science News argues the case for using electro-catalysis and heterogeneous catalysis to transform CO2 into fuels. The full article can be read on the Advanced Science News website.

CO2 is generally thought of as the primary contributor to climate change. Recently, however, the significance of CH4 as a greenhouse gas has been growing due to the emissions from shale-gas wells. Geoff’s latest opinion editorial published in Advanced Science … Continue reading →

Congratulations to Geoff for winning the WTN award in the energy category! Read more about it on the UofT News website.

In this work, published in the November 2016 issue of the Proceedings of the National Academy of Sciences, we investigate the role of oxygen vacancy and hydroxide defects on the electronic and photocatalytic properties of In2O3-x(OH)y nanocrystals that have been … Continue reading →

Professor Ozin has written numerous opinion editorials for Materials Views about hot button issues in nanochemistry. The 55 opinion editorials published so far have been organized by Geoff into a compendium of essays focusing on CO2. The full compendium of … Continue reading →

In our Advanced Energy Materials 2016 paper, we have successfully synthesized ultra-black TiO2-x nanoparticles for water evaporation by coating and superhydrophobization of them on a stainless steel mesh. Increase of x in TiO2-x resulted in a darker material leading to … Continue reading →
