Summit acid crater lakes and flank instability in composite volcanoes ...
Volcanic landslides, including flank and sector collapses, constitute a major hazard in many parts of the world. While composite volcanoes are innately unstable, the presence of a hydrothermal system maintained by a magmatic source at depth is recognized as a key factor increasing the risk of failure. This relates to the formation of hydrothermally altered rock masses within the core and upper ...

Recent Developments in Chitosan-Based Adsorbents - ProQuest
This effect of increasing tensile strength with increasing DD is usually attributed to an increase in crystallinity of the chitosan. Chitosan chains with higher DD have fewer acetyl side groups leading to a more efficient and regular packing of the polymer chains, which in turn, promotes crystallinity in the chitosan [77,85,86].

Therefore, thermal effects (e.g., melting or vaporizations) are clearly dominant for pulses with a length ranging from ms, up to even ns. Nonthermal effects arise for ps and fs laser pulses. The major advantage of ultrashort laser pulses (,1 ps) is its ability to perform clean and precise patterning (Heitz et al., 1994).

Silica helps create large flocs, and can be used with gelatin, but needs to be added first. These adjuvants will inactivate any enzymes that are present, so if enzymes are used then need to be added first. There are also some plant protein adjuvants which can be used instead of gelatin (which is animal-derived) for vegan-friendly wines.

They observed that the intensity of XRD decreases as the degree of crystallinity decreases and amorphous nature increases [42]. Thus, the incorporation of NPs with low content results in an improvement for the intermolecular interaction between the PLA chains. Thus, the degree of crystallinity for PLA/FeHA (90/10 wt.%) sample is increased.
