Chiral ceramic nanoparticles and peptide catalysis

Jiang S.; Chekini, M.; Qu, Z.-B.; Wang Y.; Yeltik A.; Liu, Y.; Kotlyar, A.; Zhang, T.; Li, B.; Demir, Hilmi Volkan; Kotov, N. A. (American Chemical Society, 2017)

The chirality of nanoparticles (NPs) and their assemblies has been investigated predominantly for noble metals and II-VI semiconductors. However, ceramic NPs represent the majority of nanoscale materials in nature. The ...

A complementary electrochromic device with highly improved performance based on brick-like hydrated tungsten trioxide film

Jiao, Z.; Wang, J.; Ke, L.; Sun, X. W.; Demir, Hilmi Volkan (American Scientific Publishers, 2012)

Uniform and well adhesive nanostructured hydrated tungsten trioxide (3WO 3•H 2O) films were grown on fluorine doped tin oxide (FTO) substrate via a facile and template-free crystal-seed-assisted hydrothermal method by ...

Gate bias characterization of CNT-TFT DNA sensors

Aktaş, Özgür; Töral, Taylan (IEEE, 2009-12)

This paper follows the approach in the works of Gui et al. (2007), that use the change in the current of carbon nanotube thin film transistors (CNT-TFT) with DNA attachment and DNA hybridization. The authors have studied ...

Noncontact lateral-force gradient measurement on Si(111)-7×7 surface with small-amplitude off-resonance atomic force microscopy

Atabak, M.; Ünverdi O.; Özer H.O.; Oral, A. (2009)

In this work, the authors report on a quantitative investigation of lateral-force gradient and lateral force between a tungsten tip and Si (111) - (7×7) surface using combined noncontact lateral-force microscopy and scanning ...

Sub-Angstrom oscillation amplitude non-contact atomic force microscopy for lateral force gradient measurement

Atabak, M.; Ünverdi O.; Özer H.O.; Oral, A. (2009)

We report the first results from novel sub-Angstrom oscillation amplitude non-contact atomic force microscopy developed for lateral force gradient measurements. Quantitative lateral force gradients between a tungsten tip ...
