11. Utilizing Biopolymers in 3D Tumor Modeling and Tumor Diagnosis
Abstract : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.

14. Water-Induced Charge Transport in Microcrystalline Cellulose
Abstract : Microcrystalline cellulose (MCC) is the most frequently used excipient for direct compaction of tablets within the pharmaceutical industry. It has earlier been indicated that the interactions between the hydration shell – surrounding the drug molecules in an MCC tablet – and the cellulose regulate the speed of the drug release process.

15. Antimicrobial materials from cellulose using environmentally friendly techniques
Abstract : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.
