Li et al. explored novel amphiphilic oleoyl-carboxymethyl chitosan self-assanbled nanoparticles [147]. Morris et al., investigated the effect of prolonged storage at different temperatures on the particle size distribution of tripolyphosphate (TPP) -chitosan nanoparticles and it was observed that fabricated nanoparticles showed uniform particle size distribution [129]. In one study, novel MPEG-chitosan diblock copolymer and self-assembly of nanoparticles were explored [148]. In another study self-assembled nanoparticles of 6-0-cholesterol-modified chitosan for drug delivery were fabricated [149]. These nanoparticles were reported for their improved delivery.

A considerable viscosity increase in copolymers of tributylstannyl methacrylate with methyl methacrylate, butyl acrylate and styrene upon prolongated storage has been observed and special agents to eliminate this effect have been proposed 108). It is likely that the destruction of intermolecular coordination complexes formed by involvement of tin and carbonyl groups in comonomer units takes place in this case. 

A powerful explosion which occurred dining distillation of a 10-year-old sample of the alcohol was attributed to presence of peroxy compounds formed by autoxidation, possibly involving 2-butanone as an effective photochemical sensitiser [1], After a later explosion, it was found that the sample being distilled contained 12% of peroxide [2], A further incident involved a 12-year old sample which exploded at the end of distillation, and which also contained a high level of peroxide. Several other stock alcohols were found to contain much lower levels of peroxide than the 2-butanol, and recommendations on clean-up or disposal, depending on the level of peroxide, are made [3], A further report of an explosion at the end of laboratory distillation confirms the potential for peroxide formation on prolonged storage of 2-butanol [4],...

The effects of storage on lipids depend on potato variety (Mondy et al., 1963). Tuber storage at 4°C resulted in an initial small increase in total fatty acid content (Dobson et al., 2004). Prolonged storage resulted in a fall to the initial values detected close to harvest. The content...
