The role of the oxidic support on the deactivation of Pt catalysts during the CO2 reforming of methane [PDF]

open access: yes, 1996
Pt supported on ¿-Al2O3, TiO2 and ZrO2 are active catalysts for the CO2 reforming of methane to synthesis gas. The stability of the catalysts increased in the order Pt/¿-A12O3 < Pt/TiO2 < Pt/ZrO2.

An investigation of the effects of total hip arthroplasty with femoral shortening in unilateral Crowe type-IV dysplastic hips on sagittal spinopelvic parameters

open access: yesMedicine Science, 2022
It has been reported that sagittal spinal alignment may become abnormal in patients with hip osteoarthritis. There is limited data in the literature on how spinopelvic parameters change after total hip arthroplasty (THA) with femoral shortening in ...

Dinuclear platinum(II) sulfide–thiolate complexes [Pt₂(μ-S)(μ-SR)(PPh₃)₄]⁺ containing fluorinated substituents and the identification of a SC₆F₅ π interaction in the crystal structure of [Pt₂(μ-S)(μ-SCH₂C₆F₅)(PPh₃)₄]BPh₄•2C₆H₆ [PDF]

open access: yes, 2011
Reactions of the platinum(II) sulfido complex [Pt₂(μ-S)₂(PPh₃)₄] with the alkyl iodides ICH₂CH₂(CF₂)nCF₃ (n = 3, 7) gives good yields of the monoalkylated products [Pt₂(μ-S){μ-SCH₂CH₂(CF₂)nCF₃}(PPh₃)₄]⁺, which were isolated as PF₆⁺or BPH₄⁻ salts, and ...

Optically driven silicon-based quantum gates with potential for high-temperature operation [PDF]

open access: yes, 2003
We propose a new approach to constructing gates for quantum information processing, exploiting the proper-ties of impurities in silicon. Quantum information, embodied in electron spins bound to deep donors, is coupled via optically induced electronic ...

Site-dependent charge transfer at the Pt(111)-ZnPc interface and the effect of iodine [PDF]

open access: yes, 2014
The electronic structure of ZnPc, from sub-monolayers to thick films, on bare and iodated Pt(111) is studied by means of X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS) and scanning tunneling microscopy (STM).

Pt, Co–Pt and Fe–Pt alloy nanoclusters encapsulated in virus capsids

open access: yesNanotechnology, 2016
Nanostructured Pt-based alloys show great promise, not only for catalysis but also in medical and magnetic applications. To extend the properties of this class of materials, we have developed a means of synthesizing Pt and Pt-based alloy nanoclusters in the capsid of a virus.
