In this study we used atom transfer radical polymerization to graft poly(N-isopropylacrylamide) (PNIPAAm) onto flat Si substrates. We then applied very large-scale integration and reactive ion etching sequentially to generate 200-nm-scale hole arrays of tethered PNIPAAm as two-dimensional periodic concave gratings (2DPCGs) on the Si surfaces. The hole array(More)
Root length and root length density of Lespedeza bicolor, Amorpha fruticosa, and Sea buckthorn were investigated in a country highway-TongSan highway (Tongjiang to Sanya) in Heilongjiang Province, China. The root lengths were divided into five root orders according to Pregizter sequence classification method. Results show that sea buckthorn roots are(More)
Temperature is the most sensitive environment factor for the blooming period of apple. Temperatures at different levels were measured by automatic micro-climatic gradient system in the blooming periods from 2011 to 2014, in two Fuji apple orchards with two different tree ages and structures [small canopy open center shape (SMCOCS) and freedom spindle shape(More)
