We present an integrated light-electron microscope in which an inverted high-NA objective lens is positioned inside a scanning electron microscope (SEM). The SEM objective lens and the light objective lens have a common axis and focal plane, allowing high-resolution optical microscopy and scanning electron microscopy on the same area of a sample simultaneously. Components for light illumination...

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are widely used in material science, metallurgy sicence and life science researches. TEM is an imaging technique where a beam of electrons is focused onto a specimen causing an enlarged version to appear on a fluorescent screen or layer of photographic film. SEM is a technique of electron microscope to produce high re...

Internal and surface structures of asci and ascospores were studied by transmission electron microscopy (TEM) and by scanning electron microscopy (SEM) to establish the character and number of ascospores within the ascus of Metschnikowia krissii. Enzyme digestion with snail gut enzymes and SEM examination suggested the presence of a single ascospore enclosed in a thick sheath of epiplasmic mate...

The aim of this study was to investigate the effects of breading materials and two different frying oils on the fat up-take in the fish fillets during frying process. Breaded and non-breaded black pomfret (Parastromateus niger) fillets were fried in sunflower oil and palm olein. Fat content by Soxhelet method and scanning electron microscopy (SEM) was studied. Results from Soxhelet method showe...

A total sample preparation method utilizing one membrane filter for all or some of the measurements by phase contrast optical microscopy (PCM), optical microscopy (OM), dispersion staining polarized microscopy (DS/PLM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), was developed in order to evaluate airborne asbestos and other mineral fibers comprehensively, in...

The rationale of correlative light and electron microscopy (CLEM) is to collect data on different information levels--ideally from an identical area on the same sample--with the aim of combining datasets at different levels of resolution to achieve a more holistic view of the hierarchical structural organization of cells and tissues. Modern three-dimensional (3D) imaging techniques in light and...

the dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. cu and ni unites nanocatalyst powders sithcomposition of caned], and nife204 were synthesized by a sol-gel auto catalnic combustion process. themolar ratio between metal ions and urea was 11.2. the sob gel process was done at 8...

in the present study, pathogenicity of four native strains of entomopathogenic fungus; metarhizium anisopliae, was studied against adult stage of ixodes ricinus. for this purpose a total number of 180 adult ticks were examined in triplicate. thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. samples were incubated in separate pet...
