in the current paper,nanostructured nickel oxide (nio) were synthesized by co-precipitation method using nickel(ii) chloride hexahydrate (nicl2.6h2o) and sodium hydroxide (naoh) as starting material. structural, optical and magnetic properties of nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), atomic force microscope (afm), uv–vis absorption; fo...

we report on the synthesis, morphology, chemically and structurally of la2o3-co3o4-zro2 nanostructure. the la2o3-co3o4-zro2 nanostructure was synthesized by a method based on the co-precipitation. composite powders have been characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and bet (brunauer-emmett-teller). x-ray diffraction showed the formation of nano crystalline, l...

We review the use of scanning electron microscopy (SEM), atomic force microscopy (AFM) and force spectroscopy (FS) for probing the ultrastructure, chemistry, physical characteristics and motion of fungal cells. When first developed, SEM was used to image fixed/dehydrated/gold coated specimens, but here we describe more recent SEM developments as they apply to fungal cells. CryoSEM offers high r...

This special issue of Microscopy and Microanalysis contains 17 articles from a topical conference on microbeam characterization of nonconductive materials. The conference was held at the Department of Mining, Metals, and Materials Engineering of McGill University in Montreal on August 2–3, 2002, as the pre-meeting congress prior to the Microscopy & Microanalysis 2002 meeting in Quebec City, Can...

In the present work, we report a suitable approach for the preparation of BaTiO3 nanostructures via the hydrothermal condition using Dolapix ET85 as surfactant. The powders were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), field emission transmission electron microscopy (FETEM), selected area electron diffra...

We present a new micrometer-sized 3D calibration structure containing nanomarkers that serve as well distinguishable reference points for the calibration of various 3D micro-range measurement methods, e.g. scanning electron microscopy (SEM) and environmental SEM (ESEM). The 3D calibration object was fabricated using gas-assisted focused ion beam (FIB) metal deposition. This technique proved to ...

The typically distinctive and elaborate external structures and sculpturing of pollen grains have been widely used in the taxonomy and systematics of the flowering plants. The family Acanthaceae is a striking example, where the widely diverse external pollen grain morphology has proved useful in determining relationships between taxa. Detailed information for external pollen wall morphology has...

Introduction “Second best no more” was the title of an article written by David C. Joy for Nature Materials [1]. The article was for highlighting a breakthrough made by a team formed between Brookhaven National Laboratory (BNL, USA) and Hitachi High Technologies Corporation (HHT, Japan). Sub-angstrom secondary electron (SE) images were obtained on a Hitachi HD-2700, which is a combined scanning...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...
