Effects of post-lithography cleaning on the yield and performance of CVD graphene-based devices [PDF]
Beilstein Journal of Nanotechnology, 2019 The large-scale production of high-quality and clean graphene devices, aiming at technological applications, has been a great challenge over the last decade. This is due to the high affinity of graphene with polymers that are usually applied in standard lithography processes and that, inevitably, modify the electrical proprieties of graphene.

Estimation of Clean-wool Yield from Small Samples
Nihon Chikusan Gakkaiho, 1958 1. 緬羊の全フリース洗毛歩留を小試料から推定する目的で,1954年から1956年までに北海道農業試験場畜産部で飼育していた緬羊39頭(雌38,雄1)がら試料を得た。2. 肩-肋-背-尻の4部位から採取した汚毛小試料20g,10g,5gの各洗毛歩留について分散分析した結果,これらの重量間には有意差は認められなかつたが,部位間には有意差が認められた。すなわち肩•肋の2部位で,背部との間に有意差が認められた。3. 小試料について,石油エーテルの方法とマルセル石鹸を使用する洗毛方法との間には,洗毛歩留の有意差小試料による全フリース洗毛歩留の推定法は認められなかつた。4.
