    Notes: Abstract Silicon was etched in an aqueous solution of sodium hydroxide under ir laser irradiation. Two types of lasers were used, a Nd:YAG laser with a wavelength of λ=1.06 μm and a CO2 laser with λ=10.6 μm. Small-size blind holes, through holes and reliefs were formed on a Si target, and even a special type of hole can be formed with help of a CO2 laser, namely a blind hole with a hillock in its center.

    Notes: Summary Paramylon is the β-1,3 glucan storage carbohydrate in the euglenoid algae. Mature paramylon granules are highly crystalline, fibrillar, and have a complex substructure. X-ray diffraction was used to demonstrate that mature paramylon granules are much more crystalline than immature granules. Freeze-etch electron microscopy showed that in mature granules, the microfibrils are organized in highly ordered arrays while the microfibrils of immature granules are less organized. The data suggest that the high crystallinity of paramylon is due to higher-order aggregates of microfibrils and the interaction of water with the microfibrils. The dissolution of paramylon was recorded by darkfield videomicroscopy. In a 0.5 N NaOH solution, paramylon dissociates in a regular manner into its constituent 4 nm microfibrils, and the central region of the granule is the last remaining refractile area during the dissolution process.
