Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

Technical Review of Hydrothermal Formation of Calcium Copper Tetrasilicate Introduction Scanning electron microscopy (SEM) is used to obtain close-up images of samples with depth enabling high quality, 3D depictions on a microscopic level. It has been historically used to identify samples of interest such as bacterial biofilm, microtexture surfaces, and even cancer cells for diagnosis.[1, 2, 3] The first high magnification SEM was reported in a journal in 1938 by Ardenne after developing the…

3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…

diplococci, streptococci, staphylococci, diplobacillus, and streptobacillus. Fresh yoghurt – under 40x magnification Fresh yoghurt – under 100x magnification Results/Analysis A. Identification and function of different parts of the microscope: * Stage – is where the specimen is placed. * Clips – hold the specimen in place. * Lamp – produces the light. * Condenser – a lens that focuses and aligns the light from the lamp to the specimen. * Diaphragm – is located…

methylene and water).Wet mounts are used with a piece glass concave slide and a solid object for viewing it. A drop of water or other liquid substances is dropped onto the object and a cover slip is slid on top of the liquid. The tension of the surface of the water automatically will close the cover tight to the slide while still holding the object in place for accurate, focused viewing. Dry mounts are also used with a piece of a flat slide but only with a solid object instead of dropping liquid…

If the bacteria stains negative, the bacteria will not retain the purple/blue color, but rather have a pinkish/red color. From my result in Fig 1 below, under the microscope,the bacteria stain positive and retain a purple/blue color. Fig. 1.Gram-positive bacteria appeared purple/blue color under the microscope. A typically gram positive reaction exhibited by Staphylococcus aureus. These organisms characteristically retain the primary dye, usually crystal violet,and appear dark purple…

causing it to eat less. Some problems that I may have encountered while doing the experiment was making sure not to kill the Tetrahymena. In order to solve that problem the slide covers had to be put on very slow and gentle. Another problem that was encountered was the Tetrahymena moving too fast while looking into the microscope. Glutaraldehyde was put in the solution to stop the Tetrahymena from moving. A problem we faced was there not being enough Tetrahymena. In order to make sure we had…

Microscopic Examination Hypothesis: A compound microscope will reveal cellular level images through magnification. Abstract: The purpose of this lab is to acquaint nursing students to a real live laboratory setting and to introduce microscopic analysis. There were two objectives for this laboratory study: [1] Learn how to handle to microscope and familiarize its structural functions, and [2] examine real live specimens through microscopy. Introduction A microscope is a fundamental equipment…

Purpose Statement: The purpose of this experiment was to determine the Gram stain of the certain slant cultures we used in class, Escherichia coli and Staphylococcus aureus, under a microscope. Since it is the most important staining procedure in microbiology, it is used to distinguish between gram-positive and gram-negative organisms. The gram-positive cells stain purple, and the gram-negative stain a pinkish color. This staining is a differential stain that allows is used to identify the…

A. List the following parts of the microscope and describe the function of each 1. Eyepiece: x10 or x15 lenses used to look through to view objects within the viewing field 2. Eyepiece Tube: holds the eyepiece 3. Main Tube: moves vertically for focusing 4. Coarse Adjustment: Used for the initial focusing of the viewing field 5. Fine Adjustment knob: Used for the final focusing of the viewing field 6. Stage: holds the specimen or slide 7. Diaphragm: controls the volume…
