Carbon supported nano-sized Pt-Pd and Pt-Co electrocatalysts for proton exchange membrane fuel cells

Kadirgan, F.; Kannan, A. M.; Atilan, T.; Beyhan, S.; Ozenler, S. S.; Suzer, S.; Yörür, A. (2009)

Nano-sized Pt-Pd/C and Pt-Co/C electrocatalysts have been synthesized and characterized by an alcohol-reduction process using ethylene glycol as the solvent and Vulcan XC-72R as the supporting material. While the Pt-Pd/C ...

Continuous mesoporous pd films by electrochemical deposition in nonionic micellar solution

Iqbal, M.; Li C.; Wood, K.; Jiang B.; Takei, T.; Dag, Ö.; Baba, D.; Nugraha, A. S.; Asahi, T.; Whitten, A. E.; Hossain, M. S. A.; Malgras, V.; Yamauchi, Y. (American Chemical Society, 2017)

Mesoporous metals that combine catalytic activity and high surface area can provide more opportunities for electrochemical applications. Various synthetic methods, including hard and soft templating, have been developed ...

FTIR spectroscopic study on nickel(II)-exchanged sulfated alumina: nature of the active sites in the catalytic oligomerization of ethene

Davydov, A. A.; Kantcheva, M.; Chepotko, M. L. (Springer, 2002)

The nature of the active sites in nickel(II)-exchanged sulfated alumina in the reaction of ethene oligomerization has been studied by means of FTIR spectroscopy of adsorbed CO. It has been established that isolated nickel(I) ...

In situ synthesis of biomolecule encapsulated gold-cross-linked poly(ethylene glycol) nanocomposite as biosensing platform: A model study

Odaci, D.; Kahveci, M.U.; Sahkulubey, E.L.; Ozdemir, C.; Uyar T.; Timur, S.; Yagci Y. (Elsevier BV, 2010)

In situ synthesis of poly(ethylene glycol) (PEG) hydrogels containing gold nanoparticles(AuNPs) and glucose oxidase (GOx) enzyme by photo-induced electron transfer process was reported here and applied in electrochemical ...

Oligomerization of ethylene in a slurry reactor using a nickel/sulfated alumina catalyst

Zhang, Q.; Kantcheva, M.; Dalla Lana, I. G. (American Chemical Society, 1997)

During the oligomerization of ethylene over heterogeneous catalysts, the production of α-olefins may be lowered because of an accompanying deactivation of catalyst resulting from strong adsorption of products, by isomerization ...

Sterilization of PMMA microfluidic chips by various techniques and investigation of material characteristics

Yavuz, C.; Oliaei, S. N. B.; Cetin, B.; Yesil-Celiktas, O. (Elsevier, 2016)

The sterilization of microfluidic chips is a vital step of the fabrication process prior to the customer use in biomedical applications. The aim of this study was to analyze the influence of different sterilization techniques ...

Transition-metal-ethylene complexes as high-capacity hydrogen-storage media

Durgun, E.; Ciraci, S.; Zhou, W.; Yildirim, T. (American Physical Society, 2006)

From first-principles calculations, we predict that a single ethylene molecule can form a stable complex with two transition metals (TM) such as Ti. The resulting TM-ethylene complex then absorbs up to ten hydrogen molecules, ...

Tuning the degree of oxidation and electron delocalization of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) with solid-electrolyte

Vempati S.; Ertas Y.; Celebioglu A.; Uyar T. (Elsevier, 2017-10)

We report on the effects of ionic interaction on the electronic structure of PEDOT:PSS where the oxidation state of PEDOT is an import aspect for various applications. Additional ionic interactions are introduced and ...
