1. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. LÄS MER
2. Dissolution rates of mineral nitrogen fertilisers : effects of moisture and precipitation
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and EnvironmentSammanfattning : Hygroscopicity and deliquescence refer to the ability of a solid to absorb air moisture in which it dissolves and have long been recognised as properties having negative impacts on the product quality of explosives, pharmaceuticals, and fertilisers. Contrastingly, this thesis reconsiders and reappraises the hygroscopic effects of common mineral fertilisers, proposing hygroscopicity to beneficially enable quick dissolution under humid air conditions in absence of precipitation.

3. Finger-jointing of acetylated Scots pine using a conventional MUF resin
Master-uppsats, KTH/ByggnadsmaterialSammanfattning : Acetylation of wood is a modification technique that chemically alters the wood substance and enhances several properties of wood. The basic principle is to impregnate wood with acetic anhydride to react and replace OH-groups with acetyl groups in the wood cell wall. LÄS MER
