Ultrathin (∼3 Å) zirconium oxide films were grown on a single-crystalline Pt3Zr(0001) substrate by oxidation in 1 × 10-7 mbar of O2 at 673 K, followed by annealing at temperatures up to 1023 K. The ZrO2 films are intended to serve as model supports for reforming catalysts and fuel cell anodes. The atomic and electronic structure and composition of the ZrO2 films were determined by synchrotron-b...

Electrochemical partial reforming of organics provides an alternative strategy to produce valuable organic compounds while generating H2 under mild conditions. In this work, highly selective electrochemical reforming of ethanol into ethyl acetate is successfully achieved by using ultrathin Co3O4 nanosheets with exposed (111) facets as an anode catalyst. Those nanosheets were synthesized by a on...

Ultrathin multilayers are important for electrical and optical devices, as well as for immunoassays, artificial organs, and for controlling surface properties. The construction of ultrathin multilayer films by electrostatic layer-by-layer deposition proved to be a popular and successful method to create films with a range of electrical, optical, and biological properties. Dendrimer nanocomposit...

Quantitative analysis of anatomical synaptic connectivity in microcircuits depends upon accurate three-dimensional (3D) reconstructions of synaptic ultrastructure using electron microscopy of serial ultrathin sections. Here we address two pitfalls in current methodology that lead to inaccurate reconstructions and compromise conclusions drawn from the data. The first pitfall is inaccurate determ...

Ultrathin, two-dimensional (2D) nanosheets of layered transition-metal chalcogenides are theoretically and technologically intriguing. However, it still remains a great challenge to synthesize ultrathin nanosheets because of the lack of an intrinsic driving force for the anisotropic growth of 2D superposed microstructures. Here we demonstrate, for the first time to our knowledge, the in situ sy...

Osteoblast differentiation can be modulated by variations in order of nanoscale topography. Biopolymers embedded with carbon nanotubes can cause various orders of roughness at the nanoscale and can be used to investigate the dynamics of extracellular matrix interaction with cells. In this study, clear relationship between the response of osteoblasts to integrin receptor activation, their phenot...

The aim of this study was to assess the clinical value of radial probe endobronchial ultrasound (RP-EBUS)-guided localization of solitary pulmonary nodules (SPNs) with the combination of ultrathin bronchoscopy and methylene blue prior to video-assisted thoracoscopic surgery (VATS). An ultrathin bronchoscope was used to localize the lesions under RP-EBUS guidance in 48 patients (18 men and 30 wo...

This paper describes an original method for forming a stable coating on polypropylene yarn. The use of this provides yarn with barrier antimicrobial properties, reducing its electrical resistance, increasing strength, and achieving extremely high chemical similar to that fluoropolymer yarns. is applied at the melt-spinning stage It based ultrathin, continuous, uniform surface each filaments. fo...

Ordered ultrathin films of tris(1,10-phenanthroline-4,7-diphenylsulfonate)ruthenium(ii) anions and cationic layered double hydroxide monolayers have been fabricated by the layer-by-layer assembly technique and show well-defined polarized red luminescence.
