The Difference

The morphological surface change of untreated and treated fibers of the Mongolian goat cashmere was investigated by atomic force microscopy (AFM) at ambient conditions. The cuticle scale heights of the Mongolian goat cashmere fibers were measured by the AFM for the fibers before and after treatment. The experimental results showed that the difference between the fine structure of the cuticle and surface roughness of untreated and treated fibers. We found that the surface morphological change of the cashmere fibers was strongly degraded after the bleaching process.

Exhaustive Extraction

Bovine nasal cartilage was studied by electron microscopy before and after extraction with 4 M guanidinium chloride or 1.9 M CaCl2. These solvents removed matrix granules, basophilia, and 85% of the proteoglycan complex, measured as hexuronate. Simultaneously, many collagen fibrils were disaggregated into component microfibrils (approximately 40 A thick). In contrast to the above solvents, exhaustive extraction with 0.5 M guanidinium chloride removed 20% of the proteoglycan complex, and matrix granules were reduced in size but not in number. Extraction with 4 M CaCl2 removed only 10% of the proteoglycan complex, did not remove matrix granules, and caused the normal banding pattern of collagen to disappear. The banding was restored by further treatment with trypsin. Trypsin, before or after 4 M CaCl2, removed matrix granules and 90% of the proteoglycan complex. We conclude that matrix granules are an electron microscopic representation of the proteoglycan complex, and consist of more than one proteoglycan macromolecule. It would appear that 4 M guanidinium chloride and 1.9 M CaCl2, in addition to removing most of the proteoglycan complex, also disaggregate some of the collagen fibrils into their component microfibrils.

It has been shown that a single injection of 8.0 mg/kg of the cis (Pt(NH3)2cl2) in normal saline is effective in regressing solid Sarcoma-180 tumors in Swiss White mice, with no apparent irreversible damage to the host. Present investigations were undertaken to study the fine structure of Sarcoma-180 under experimental and control conditions. Platinum injections were made on day 10, (taking the tumor implant as day 0), and the animals were sacrificed at 2 day intervals for 12 days after the injections. The tissue from injected and uninjected animals was processed for electron microscopic studies.

AbstractX-ray Photo Emission Electron Microscopy (X-PEEM) and Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy were applied to study the properties of amorphous hard carbon overcoats on disks and sliders, and the properties of the lubricant. The modification of lubricants after performing thermal desorption studies was measured by NEXAFS, and the results are compared to thermal desorption data. The study of lubricant degradation in wear tracks is described. Sliders were investigated before and after wear test, and the modification of the slider coating as well as the transfer of lubricant to the slider was studied. The studies show that the lubricant is altered chemically during the wear. Fluorine is removed and carboxyl groups are formed.
