Reflective materials enhance ‘Fuji’ apple color [PDF]

open access: yesCalifornia Agriculture, 1996
Red color development is an important factor for consumer acceptance of California "Fuji" apples. Several attempts to improve red color development, including delaying harvest, have been unsuccessful in warm production areas. In California, late harvest has been associated with physiological problems such as skin cracking and internal browning. A study

Novel materials to enhance keratoprosthesis integration [PDF]

open access: yesBritish Journal of Ophthalmology, 2000
The successful integration of keratoprostheses (KPros) within the cornea depends in part on peripheral host keratocyte adhesion to anchor the implant in place and prevent epithelial downgrowth. The following study incorporated different acrylate co-monomers with poly(hydroxyethyl methacrylate) (p(HEMA)) and measured the suitability of these materials ...

Low-Frequency Noise Behavior of AlGaN/GaN HEMTs with Different Al Compositions

open access: yesCrystals, 2020
AlxGa1−xN/GaN heterostructures with two kinds of Al composition were grown by metal organic chemical vapor deposition (MOCVD) on sapphire substrates. The Al compositions in the AlGaN barrier layer were confirmed to be 13% and 28% using high resolution X ...
