چکیده

Our TEM observation revealed that in a carbon-Pt3Co system, amorphous carbon first crystallized into nanoclusters at step-edges on melting Pt3Co surfaces before merging into graphene layers through a kinetic restructuring via oriented-attachment, leading to the final formation of few-layered graphene nanostructures. The result obtained from density-functional theory calculations further suggested that Co atoms rather than Pt atoms acted as initial nucleation centers.

Study of Dynamic Solid-Liquid Interfacial Phenomena in Hypereutectic Al-Si Alloy Using in situ HRTEM

Solid-liquid interfaces are extensively encountered in materials processing and applications. The structure and properties of these interfaces affect solidification, wetting behavior, and crystalline growth mechanisms, including epitaxial growth. The exact structural and chemical nature of these interfaces has been historically difficult to study at high resolution due to the fact that one phas...

Concentration gradient induced morphology evolution of silica nanostructure growth on photoresist-derived carbon micropatterns

The evolution of silica nanostructure morphology induced by local Si vapor source concentration gradient has been investigated by a smart design of experiments. Silica nanostructure or their assemblies with different morphologies are obtained on photoresist-derived three-dimensional carbon microelectrode array. At a temperature of 1,000°C, rope-, feather-, and octopus-like nanowire assemblies c...

Direct observation of layered structures at ionic liquid/solid interfaces by using frequency-modulation atomic force microscopy.

Presence of inhomogeneous layered structures of ionic liquid (IL) molecules at IL/HOPG and IL/mica interfaces was directly detected and imaged by using frequency-modulation atomic force microscopy. High stability of the layered structures may disturb their interface applications to catalysis and electrochemistry.

Role of activated carbon from natural adsorbent for removal of textile dyes: effect of pH, kinetic and adsorbent mass

In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

Direct observation of liquid nucleus growth in homogeneous melting of colloidal crystals

The growth behaviour of liquid nucleus is crucial for crystal melting, but its kinetics is difficult to predict and remains challenging in experiment. Here we directly observed the growth of individual liquid nuclei in homogeneous melting of three-dimensional superheated colloidal crystals with single-particle dynamics by video microscopy. The growth rate of nucleus at weak superheating is well...
