Atomic force microscopy (AFM) has been used to study the hollow cavity formation mechanisms of the L-arginine phosphate monohydrate (LAP) crystals. Hollow cavities are formed through three modes. During 2D nucleation growth, initially formed 2D cavity prevents the growth around it layer-by-layer...

High-quality Nd:LuVO4 thin films have been grown on silica glass substrates by using a pulsed laser deposition technique. X-ray diffraction results show that the as-deposited Nd:LuVO4 film is basically oriented polycrystalline, and strong (200) peak was revealed. The waveguide property was...

Tunneling effect of graphite is studied by atomic force microscopy. The tunneling current in the gap between a conductive tip and a newly cleaved graphite surface at a given voltage keeps almost constant when the gap-distance varies within 1 μm, which cannot be explained by the commonly...

Morphology of the {100} cleavage faces of L-arginine phosphate monohydrate single crystal before and after its growth at 40°C at a supersaturation of 0.031 has been studied. Monolayer and multilayer steps are found on the original cleaved surfaces. The regrowth morphology varies in nature with...

Cr/SmCo5/Cr films were fabricated by a DC facing targets magnetron sputtering. The influences of sputtered Ar pressure and substrate temperature on their microstructure and magnetic properties were investigated. Magnetic measurements indicate that the optimal substrate temperature was 450°C,...

Dislocation growth and microcrystals are investigated on the {110} faces of MMTC crystals grown from aqueous solution. Growth of MMTC crystals occurs in elementary steps (~ 0.81 nm), introduced by both simple and complex dislocation sources. The bright particles with regular sizes and shapes are...

The discovery of the single-walled carbon nanotubes (SWCNTs) with a diameter of 0.4 nm has attracted extensive attentions. In this paper we report our attempt with two methods to directly observe these SWCNTs by AFM. The first one is to deposit the SWCNTs extracted from the zeolite matrix to a...

The processes of nickel electrodeposition on Pt/Si(100) substrate from an aqueous sulfate, Watts, and chloride solution have been studied using electrochemical techniques and atomic force microscopy (AFM). It was found that hydrogen evolution reaction (HER) was shifted more cathodically and the...

Lead-free Bi0.5(Na0.4K0.6)0.5TiO3 films have been synthesized by a chemical solution deposition method and deposited on p-Si(111) substrate by spin coating. Powder of the precursor solution heated at 650°C was studied by infrared scattering spectroscopy. The structural characteristics and...

Herein, we showed a different approach to directly single-molecule level visualization of the degradation of DNA in vitro tests using DNase I incubation based on high-resolution AFM imaging ex situ with fine relocation nanotechnology. A method of nanomanipulation termed as "modified dynamic...
