Solar Cell Made Using Graphene

“…If it is made starting with a suspension of nonfunctionalized flakes (5), the resulting material is porous and extremely fragile and can float in air like a feather. However, the same paper made of graphene oxide is dense, stiff and strong (6,32). In the latter case, the functional groups bind individual sheets together, which results in a microscopic structure not dissimilar to that of nacre known for its strength.…”

“…This is often led by analogies with carbon nanotubes that continue to serve as a guide in searching for new applications. For example, graphene powder is considered to be excellent filler for composite materials (6). Reports have also been made on graphene-based supercapacitors, batteries and field emitters, but it is too early to say whether graphene is able to compete with the other materials, including nanotubes.…”

Stasis Dermatitis in a Patient With Noonan's Syndrome

“…In spite of the high morbidity of varix and stasis dermatitis in Caucasians, these conditions rarely occur in the Japanese. In the records at the Department of Dermatology at Tohoku Ilnizersity, Saito et al (8)f()undonly 9 cases of varix, one of stasis dermatitis, and 5 of ulcus cruris among 16,553 outpatients over 5 years. All of these cases were well over 21 years of age.…”
