We have synthesized and characterized four different stable phases of Na ordered Na x CoO 2 , for 0.65< x <0.8. Above 100 K they display similar Curie-Weiss susceptibilities as well as ferromagnetic q =0 spin fluctuations in the CoO 2 planes revealed by 23 Na NMR data. In all phases from 59 Co NMR data we display evid…

Both the ferroelectric and magnetic properties of polycrystalline BiFeO3 films fabricated by chemical solution deposition were enhanced by adding small amounts of cobalt. Addition of 3at.% cobalt to BiFeO3 films increased the remanent polarization from 49to72μC∕cm2 and decreased the electric coercive field from 0.54to…

We here report on the formation of well-ordered 2D gold nanostructures at the air/water interface. Spreading a mixture of alkanethiol-capped gold nanoparticles (AuNPs) and an amphiphilic poly(p-phenylene) on a water surface and compressing the mixture to a surface pressure of 40 mN/m lead to the formation of a network…

Abstract This article presents the results from a study of yarn‐to‐yarn (YY) and yarn‐to‐metal (YM) frictions conducted on ring, rotor, air‐jet, and open‐end friction (OE friction) spun yarns at different relative speeds and input tensions. The results indicate that the behavior of frictions for YY is different than t…

We investigate the kinetics of self-assembly by means of Brownian dynamics simulation based on a idealized fluid model (two ‘sticky’ spots on a sphere) in which the particles are known to form into dynamic polymer chains at equilibrium. To illustrate the slow evolution of the properties of these self-assembling fluids…

Modification and control of surface function on porous materials have been a very promising and appealing area of chemistry. In this paper, the reason as to why it is impossible to generate a strong basicity on silica and titania is explored in detail, and consequently, a new strategy was adopted to overcome this obst…
