One of the most undesirable properties concrete is that cracks due to many reasons including shrinkage and applied loads. Normal has tendency seal these on its own utilizing un-hydrated cement particles deposited fine particles. This a very limited success deal with live expanding cracks. study helps by using Ultra-High Absorbent Polymer (UHAP). polymer absorbs large quantity water form gel-lik...
Root growth and development of maize (Zea mays L.) is an important process in determining grain yield. The effects combined fulvic acid (FA, potassium humate as FA source) super absorbent polymer (SAP) uses on root yield were studied. A 2Ã3 factorial field experiment was applied by combining two SAP doses (0, 45 kg ha-1) three rates 1, 2 g L-1) over yr. Super to upper 20 cm soil layer at sowin...
Photoinduced intramolecular charge separation (CS) in a polar polymer glass, cyanoethylated pullulan (CN-PUL), was studied below the glass transition temperature (Tg=395 K). A series of three carbazole (Cz: donor)-cyclohexane (S: spacer)-acceptor (A: acceptor) molecules (Cz-S-A) was used as intramolecular donor-acceptor dyads. The photoinduced CS rate was evaluated by the fluorescence decay mea...
