    The Comfort Dimension: a Review of Perception in Clothing
    (Journal of sensory studies, 2013) Kamalha, Edwin; Zeng, Yongchun; Mwasiagi, Josphat I.; Kyatuheire, Salome
    For a clothing system, comfort is a fundamental necessity. In this paper, basic definitions and elements of clothing comfort and the general research trends were reviewed. In particular, understanding comfort of textile materials, its relevance to clothing choice and some assessment methods have been discussed. The impact of fabric and clothing attributes on clothing comfort was explored. Psychological, physical and physiological perceptions of clothing comfort were reviewed, including subjective and objective modes of assessment. A thorough discussion of handle comfort was presented, including assessment methods. Statistical presentations from selected comfort studies were also reviewed. Other sensory comfort properties particularly acoustic and appearance were also mentioned. From the aforementioned reviews, it was noted that the main focus for most researchers has been on sensorial and thermal comfort.

    FTIR and WAXD Study of Regenerated Silk Fibroin
    (Advanced Materials Research, 2013) Kamalha, Edwin; Zheng, Yuansheng; Zeng, Yongchun; Fredrick, Mutua N.
    In this study, regenerated Bombyx Mori (B. Mori ) silk fibroin from two aqueous solvents was analyzed for structural deviations. Results from Fourier transform infrared spectroscopy (FTIR) and Wide angle x-ray diffraction (WAXD) implied great alteration in the secondary structure, crystallinity and molecular weight due to the regeneration process.

    Nanotechnology and Carbon Nanotubes; A Review of Potential in Drug Delivery
    (Macromolecular Research, 2012) Kamalha, Edwin; Shi, Xiangyang; Mwasiagi, Josphat I.; Zeng, Yongchun
    The need for affordable health care costs and the quest for better modes of treatment have increased research in novel drug delivery techniques. Efficient drug delivery systems (DDS) are judged on their ability to perform controlled and targeted drug delivery. Several nanomaterials such as carbon nanotubes (CNTs) are widely being investigated for biomedical use due to their unique properties, as well as several functional groups and incorporated targeting molecules. This review looked at nanotechnology as an emerging field in drug delivery. Several studies and findings with regards to the current functionalization of CNTs for drug delivery were explored. The conclusion reviewed the key notes.
