GROWTH OF PURPLE CABBAGE (Brassica oleracea L. var. capitate f. rubra) ON THE ADMINISTRATION OF POLYETHYLENE GLYCOL 6000 (PEG 6000)

Jurnal Ilmiah Biologi Eksperimen dan Keanekaragaman Hayati (J-BEKH), 2021
Purple cabbage plants require an adequate supply of water in the process of growing. So that if there is a lack of water it can result in stressful conditions then the growth of purple cabbage is disrupted and can even cause death. The purpose of this study was to determine the tolerance limits of purple cabbage to PEG 6000, and to determine the effect

Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl
