Shende R.V., Puszynski J.A., South Dakota School of Mines & Technology, US

Globally increasing energy demands with reduced emission of greenhouse gases require the use of more sustainable energy sources. One of the technically viable sustainable energy technologies is based on the thermochemical water-splitting process utilizing redox [...]

Mesoporous TiO2 thin-film for Dye-Sensitized Solar Cell (DSSC) Applicationv

Vats A., Shende R., Swiatkiewicz J., Puszynski J., South Dakota School of Mines & Technology, US

The DSSC is a low-cost device as compared with the conventional ‘p-n’ junction devices. This device utilizes about 5 m thick film of TiO2 nanocrystals to form a ‘bulk’ junction with a large surface area [...]

Formation of Pyrophoric _-Fe Nanoparticles from Fe(II)-Oxalate

Shende R., Vats A., Doorenbos Z., Kapoor D., Puszynski J., South Dakota School of Mines & Technology, US

The formation of pyrophoric Fe-nanoparticles from Fe(II)-oxalate decomposition under H2 atmosphere was the main objective of this research. Iron oxalate was synthesized by controlled nucleation process involving addition of oxalic acid in the FeCl2.2H2O solution [...]

Nano-Reinforcement of Epoxy Adhesives with POSS

Chian W., Mallampalli C., Winter R.M., South Dakota School of Mines & Technology, US

ABSTRACT The reinforcement of epoxy adhesive with polyhedral-Oligomeric-SilSesquioxane (POSS) was studied. Shear performance of the nano-filled adhesive was evaluated as a function of filler content using the single-strap bonded joint configuration. It is found that [...]
